Attack Surface Analysis

Every business domain represents multiple attack vectors:

The Asymmetric Risk Problem

Investment required:

• Domain cost: $10-50/year
• Basic security: Minimal time investment
• Enterprise security: $500-5,000/year

Potential losses:

• Revenue loss: $100,000-1M+/day
• Recovery costs: $50,000-500,000+
• Brand damage: Immeasurable
• Legal liability: Potentially unlimited

The math is clear: Comprehensive domain security provides exponential ROI compared to potential losses.

Regulatory and Compliance Requirements

Industry regulations increasingly address domain security:

GDPR considerations:

• Contact information accuracy
• Privacy protection for registrant data
• Data breach notification requirements
• Third-party processor agreements

SOC 2 compliance:

• Access control documentation
• Change management procedures

• Incident response capabilities

Industry-specific regulations:

• Financial services: FFIEC, GLBA
• Healthcare: HIPAA (if PHI accessed via domain)
• Payment processing: PCI DSS
• Public companies: SOX controls

The Business Impact of Domain Compromise

Financial Consequences

Direct costs:

• Legal fees: $50,000-$500,000+ for domain recovery litigation
• UDRP filing: $1,500-$4,000 per domain
• Registry lock fees: Additional security measures post-incident
• Ransom payments: Attackers may demand payment (not recommended)

• Regulatory fines and penalties
• Loss of certifications or accreditations

Compliance violations:

• GDPR fines: Up to €20M or 4% of global revenue
• HIPAA penalties: $100-$50,000 per violation
• PCI DSS: Fines and loss of payment processing
• Industry-specific sanctions

Common Domain Security Threats

Sophisticated Phishing Campaigns

Modern phishing targeting businesses is highly sophisticated:

Spear phishing characteristics:

• Personalized messages using employee names and roles
• References to actual projects or initiatives
• Sent during business hours for legitimacy
• Use company-specific terminology and jargon
• Fake "urgent" requests from executives

Example attack flow:

1. Attacker researches company on LinkedIn, identifies IT admin
2. Crafts email appearing to be from CEO: "Please review this urgent domain renewal"
3. Links to fake registrar login page (godaddy-security-verify.com)
4. Admin enters credentials on fake site
5. Attacker immediately logs into real account using stolen credentials
6. Disables 2FA (if possible) and changes primary email
7. Initiates domain transfer to offshore registrar

Business-specific tactics:

• Fake invoice payments requiring "verification"
• Domain renewal scams with inflated prices
• Transfer authorization requests appearing official
• Registry notices about policy compliance
• SSL certificate expiration warnings

Business Email Compromise (BEC)

BEC attacks specifically target domain-based email:

Attack pattern:

1. Compromise domain registrar account
2. Change MX records to attacker's mail server
3. Intercept all company email without detection
4. Read sensitive communications for weeks
5. Execute wire transfer fraud or data theft
6. Restore original MX records to cover tracks

Financial impact examples:

• FBI reported $43 billion in BEC losses (2016-2021)
• Average loss per incident: $130,000
• Some attacks exceed $1 million
• Many incidents never publicly reported

Social Engineering Against Support Staff

Attackers exploit registrar support procedures:

Common tactics:

• Identity theft: Use publicly available WHOIS data to impersonate registrant
• Fake documentation: Submit forged identification documents
• Urgency creation: Claim emergency situations requiring immediate action
• Authority exploitation: Pose as lawyers, executives, or government officials
• Support shopping: Try multiple support agents until finding one who's lenient

Real-world example: Attacker calls registrar support claiming to be company CFO. References correct company details obtained from LinkedIn and corporate website. Claims email is compromised and needs emergency email address change. Support agent, wanting to help, makes change without proper verification. Attacker now controls account.

Insider Threats

Employees pose unique risks:

Malicious insiders:

• Disgruntled employee transferring domains before departure
• IT admin holding domains "hostage" during dispute
• Competitor-paid insider sabotaging business
• Former employee using credentials never revoked

Negligent insiders:

• Employee falling for phishing despite training
• Sharing credentials with unauthorized parties
• Using weak passwords or password reuse
• Clicking malicious links on company devices
• Storing credentials in insecure locations

Statistical reality:

• 34% of security incidents involve insiders
• Average insider attack costs $11.45 million
• Takes average 85 days to contain insider threat
• 76% of insider incidents are financially motivated

Supply Chain Attacks

Third-party risks affecting domain security:

Vendor access risks:

• Marketing agency with registrar access for DNS management
• Web developer maintaining nameserver control
• IT contractor with administrative credentials
• Previous agency never had access revoked

Compromised vendors:

• Vendor's credentials stolen in separate breach
• Vendor employee maliciously abuses access
• Vendor company acquired, access policies change
• Vendor subcontracts to unknown third party

DNS Hijacking and Cache Poisoning

Technical attacks on DNS infrastructure:

DNS hijacking scenarios:

• Compromise registrar account, change nameservers
• Compromise DNS hosting provider account
• Intercept DNSSEC validation
• BGP hijacking redirecting DNS queries
• Registrar infrastructure compromise

Cache poisoning:

• Inject fake DNS records into resolver caches
• Redirect traffic to malicious servers
• Harvest credentials from fake login pages
• Serve malware from fake download sites

Domain Transfer Fraud

Unauthorized domain transfers remain prevalent:

Transfer fraud process:

1. Gain access to registrar account (any method)
2. Disable transfer lock if possible
3. Request authorization code
4. Initiate transfer to different registrar
5. Approve transfer from compromised email
6. Transfer completes in 5-7 days
7. Transfer domain again to offshore registrar
8. Make recovery extremely difficult

Why transfers are targeted:

• Transfers can be automated and scaled
• Multiple transfers complicate recovery
• International transfers create jurisdiction issues
• Some registrars have weak reversal procedures

Essential Security Controls

Two-Factor Authentication (2FA)

2FA is the single most important security control:

Implementation requirements:

• Enable on all registrar accounts without exception
• Use authenticator apps (not SMS) for primary accounts
• Hardware security keys for highest-value domains
• Backup authentication methods documented and secured
• Regular testing to ensure 2FA remains functional

Authenticator method ranking:

Hardware key advantages for businesses:

• Resistant to phishing (domain-bound authentication)
• No device dependency (works anywhere)
• Can't be intercepted remotely
• Supports multiple accounts
• Long lifespan (5+ years)

Recommended hardware keys:

• YubiKey 5 Series: Industry standard, $45-70
• Google Titan Security Key: Budget-friendly, $30-50
• Nitrokey FIDO2: Open-source option, $30-50

Business 2FA policies:

Required Security Policy:
- 2FA mandatory for all domain management accounts
- Hardware keys required for administrator accounts
- Backup 2FA method stored in secure company vault
- 2FA bypass prohibited under any circumstances
- Quarterly audit of 2FA compliance
- Immediate 2FA reset if device compromised

Domain Locking

Multiple layers of locking protect against unauthorized transfers:

Registrar lock (Client Lock):

• Status code: clientTransferProhibited
• Protection: Prevents transfer between registrars
• Management: Self-service through registrar dashboard
• Cost: Usually free with registration
• Recommendation: Enable for ALL business domains

Registry lock (Server Lock):

• Status code: serverTransferProhibited, serverUpdateProhibited, serverDeleteProhibited
• Protection: Highest level of protection against all changes
• Management: Manual verification required for any changes
• Cost: $100-$1,500/year per domain depending on registrar
• Recommendation: Enable for critical business domains

Registry lock benefits:

• Changes require phone verification with pre-authorized contact
• Multi-step authentication before any modification
• Prevents nameserver changes without verification
• Blocks unauthorized registrant contact updates
• Some registrars offer 24-hour delay on all changes
• Creates paper trail of all modification attempts

When to use registry lock:

Cost-benefit analysis:

• Registry lock: $100-$1,500/year
• Domain theft recovery: $50,000-$500,000+
• Business downtime: $100,000-$1M+/day
• ROI: Pays for itself if prevents even 1% chance of theft

Password Security Architecture

Business password security requires systematic approach:

Password requirements:

• Minimum 20 characters (25+ recommended)
• Unique for every service (absolutely no reuse)
• Generated randomly (not human-created)
• Stored in enterprise password manager
• Rotated annually or on-demand if breach suspected

Enterprise password manager selection:

Password manager requirements:

• End-to-end encryption (zero-knowledge)
• Role-based access control
• Secure sharing between team members
• Audit logs of all access
• 2FA on password manager itself
• Offline access capability
• Emergency access procedures
• SOC 2 Type II certification

Credential isolation strategy:

Domain Security Vault Structure:
├── Domain Registrar Accounts
│   ├── Primary Registrar (Admin access)
│   ├── Secondary Registrar (Admin access)
│   └── Legacy Registrar (Read-only)
├── DNS Management
│   ├── Primary DNS Provider
│   └── Secondary DNS Provider
├── Domain Monitoring Services
└── Related Services
    ├── SSL Certificate Management
    ├── CDN Provider
    └── Email Service Provider

DNSSEC Implementation

DNSSEC prevents DNS spoofing and cache poisoning:

What DNSSEC provides:

• Cryptographic authentication of DNS responses
• Protection against DNS cache poisoning
• Verification that DNS records haven't been tampered with
• Chain of trust from root to your domain

Implementation requirements:

1. Enable at registrar: Activate DNSSEC in domain settings
2. Configure DNS host: Add DS records at DNS provider
3. Publish DNSKEY: Create and publish public key records
4. Sign zone: Generate RRSIG records for all DNS records
5. Monitor validation: Ensure DNSSEC remains valid

DNSSEC for businesses:

• E-commerce: Critical (prevents payment redirection)
• Financial services: Essential (regulatory may require)
• SaaS applications: Highly recommended
• Information websites: Recommended
• Internal domains: Consider for high-security environments

Maintenance requirements:

• Key rotation every 6-12 months
• Monitor for validation failures
• Update DS records at registrar when keys rotate
• Test DNSSEC configuration quarterly

Email Authentication

Protect domain reputation and prevent spoofing:

SPF (Sender Policy Framework):

v=spf1 include:_spf.google.com include:spf.protection.outlook.com -all

• Lists authorized email servers for your domain
• Prevents spammers from forging your domain
• Required for email deliverability

DKIM (DomainKeys Identified Mail):

• Cryptographically signs outgoing email
• Proves email originated from your domain
• Essential for email security

DMARC (Domain-based Message Authentication):

v=DMARC1; p=reject; rua=mailto:[email protected]; pct=100

• Enforces SPF and DKIM policies
• Specifies what happens to failing emails
• Provides reporting on email authentication

Business email security policy:

Phase 1 (Week 1-2): Audit
- Inventory all email sending sources
- Document current SPF/DKIM setup
- Establish DMARC in monitor mode (p=none)

Phase 2 (Week 3-6): Monitor
- Collect DMARC reports
- Identify legitimate vs. fraudulent senders
- Update SPF records for all legitimate sources

Phase 3 (Week 7-8): Enforce
- Set DMARC to quarantine (p=quarantine)
- Monitor rejection reports
- Address any false positives

Phase 4 (Week 9+): Full Protection
- Set DMARC to reject (p=reject)
- Ongoing monitoring and maintenance
- Quarterly email authentication audits

Contact Information Management

Accurate contact info is critical for security:

Registrant contact strategy:

• Use company role email ([email protected]) not personal
• Ensure email is actively monitored 24/7
• Multiple team members have access to contact email
• Physical address should be accurate (may need for disputes)
• Phone number should reach security team

Admin contact separation:

• Different from registrant contact (separation of duties)
• Reaches different team members
• Independently secure email account
• Direct line to technical team

Avoiding WHOIS privacy pitfalls:

• Privacy protection hides your info but not from registrar
• Privacy service becomes single point of failure
• Some registrars use shared privacy contacts
• Consider public info for primary domain (builds trust)
• Use privacy for supplementary domains

Enterprise Access Management

Role-Based Access Control (RBAC)

Define clear access levels and permissions:

Access tier structure:

Principle of least privilege:

• Grant minimum access required for job function
• Time-limited access for contractors and consultants
• Regular access reviews (quarterly minimum)
• Automatic access revocation after 90 days of inactivity
• Elevation process for temporary additional access

Access request workflow:

Access Request Process:
1. Employee submits formal request (ticket system)
2. Manager approves business justification
3. Security reviews access level appropriateness
4. Administrator provisions access with time limit
5. Access documented in audit log
6. User acknowledges responsibilities
7. Quarterly review confirms access still needed

Multi-Person Authorization

Critical operations require multiple approvers:

Two-person rule for:

• Domain transfers between registrars
• Registrant contact information changes
• Nameserver modifications (production domains)
• Disabling security features (locks, 2FA)
• Domain deletions
• Authorization code generation

Implementation methods:

Method 1: Separate credentials:

• Two different admin accounts required
• Each admin has unique credentials
• Both must log in and approve
• Audit log shows both approvers

Method 2: Approval workflow:

• First admin initiates action
• System notifies second admin
• Second admin reviews and approves
• Action executes only after approval
• Timeout cancels if not approved within 24 hours

Method 3: Registrar features:

• Some enterprise registrars support native workflows
• Registry lock inherently requires multi-step approval
• Custom approval processes via registrar API

Business justification:

• Prevents rogue insider from single-handedly causing damage
• Requires collusion for malicious activity (much less likely)
• Creates accountability and paper trail
• Satisfies SOC 2 and other compliance requirements

Separation of Duties

Distribute domain control across teams:

Organizational structure:

Why separation matters:

• Prevents single point of failure
• Reduces insider threat risk
• Creates checks and balances
• Improves incident detection
• Satisfies compliance requirements
• Enables business continuity

Practical implementation:

Change Control Example:
Scenario: Changing nameservers for production domain

Step 1: DNS team identifies need for change
Step 2: Submit change request with business justification
Step 3: Domain management team reviews request
Step 4: Security team verifies change doesn't introduce risk
Step 5: Manager approves change in workflow system
Step 6: DNS team executes change during maintenance window
Step 7: Monitoring confirms successful propagation
Step 8: Change documented in audit log

Employee Onboarding/Offboarding

Systematic access lifecycle management:

Onboarding checklist:

• Document business need for domain access
• Determine appropriate access level (RBAC tier)
• Manager approval for access request
• Security training completion verified
• Unique credentials created (no sharing)
• 2FA enabled before granting access
• Access documented in central registry
• Time-limited access if contractor/temp
• User signs acknowledgment of responsibilities

Offboarding checklist:

• HR notifies IT of termination/departure date
• Access revoked immediately upon departure
• Audit recent activity for suspicious behavior
• Change passwords on any shared credentials (shouldn't exist, but check)
• Review and rotate any API keys employee had access to
• Update contact information if employee was primary contact
• Document offboarding in audit log
• Confirm access revocation in registrar dashboard

Immediate revocation scenarios:

• Termination for cause
• Security incident involving employee
• Lost or stolen device with credentials
• Employee reports account compromise
• Contractor engagement ends

Critical timing:

• Planned departure: Revoke end of last day
• Termination: Revoke before notification
• Security incident: Revoke immediately (within 1 hour)

Shared Credential Elimination

Eliminate shared passwords entirely:

Why shared credentials are dangerous:

• No accountability (can't trace who did what)
• Can't revoke access for one person without affecting all
• Increased exposure (more people know password)
• Change management nightmare
• Fails compliance audits
• Enables insider threats

Migration strategy:

Shared Credential Elimination Project:

Phase 1: Audit
- Identify all shared credentials
- Document who has access to each
- Assess business justification for each shared credential

Phase 2: Replace
- Create individual accounts where possible
- For services without multi-user support, use access management tools
- Document new individual credential assignments

Phase 3: Communicate
- Notify all users of new individual credentials
- Explain security rationale
- Set deadline for transition

Phase 4: Deprecate
- Change all shared passwords on deadline
- Archive shared credentials securely
- Monitor for failed login attempts (people using old shared password)

Phase 5: Prevent
- Policy prohibiting shared credentials
- Regular audits to detect new shared credentials
- Technical controls to enforce individual accounts

Multi-Domain Portfolio Security

Domain Inventory Management

Maintain comprehensive domain inventory:

Inventory requirements:

Inventory tools:

Spreadsheet approach (small portfolios):

Domain_Inventory_2025.xlsx
├── Active Domains (in-use)
├── Parked Domains (defensive registrations)
├── Expired Domains (renewal decisions needed)
├── Transferred Domains (historical records)
└── Monitoring Status (security check summary)

Database approach (large portfolios):

• Custom internal tool
• Commercial domain management platform
• API integration with registrars
• Automated status checks
• Alert generation

Inventory audit schedule:

• Weekly: Expiration date review
• Monthly: Lock status verification
• Quarterly: Full inventory reconciliation
• Annually: Purpose review and optimization

Portfolio Risk Assessment

Prioritize security by domain criticality:

Criticality classification:

Critical (Tier 1):

• Primary business domain (company.com)
• Customer-facing applications
• Email domain for company
• E-commerce checkout domain
• Payment processing endpoints
• Critical subdomains (app.company.com)

Important (Tier 2):

• Regional variations (company.co.uk)
• Product-specific domains
• Marketing campaign domains
• Blog and content domains
• Partner-facing portals

Standard (Tier 3):

• Defensive registrations
• Alternate TLD versions
• Typosquatting protection domains
• Future project domains
• Test and development domains

Low (Tier 4):

• Expired domains (under observation)
• Legacy domains (no longer in use)
• Speculative registrations

Security requirements by tier:

Registrar Consolidation Strategy

Centralize for improved security management:

Benefits of consolidation:

• Single security posture to maintain
• Simplified 2FA and access management
• Easier monitoring and alerting
• Bulk management operations
• Better pricing through volume
• Single relationship for support
• Unified audit logs

Consolidation approach:

Portfolio Consolidation Project:

Phase 1: Assessment (Week 1-2)
- Inventory all domains across all registrars
- Document current registrar fees
- Identify domains under registry lock
- Note transfer restrictions (60-day rule)
- Calculate total consolidation cost

Phase 2: Registrar Selection (Week 3-4)
- Evaluate enterprise registrar options
- Compare security features
- Negotiate volume pricing
- Verify 2FA and access control capabilities
- Select primary and backup registrar

Phase 3: Preparation (Week 5-6)
- Unlock domains at current registrars
- Obtain authorization codes
- Verify contact information current
- Disable auto-renewal at old registrars
- Prepare DNS records for verification

Phase 4: Migration (Week 7-10)
- Transfer in batches (by tier)
- Start with non-critical domains
- Verify successful transfers
- Re-enable locks immediately
- Update monitoring systems

Phase 5: Validation (Week 11-12)
- Confirm all domains transferred
- Verify all security settings enabled
- Update inventory with new registrar
- Close accounts at old registrars
- Document new procedures

When to use multiple registrars:

• Very large portfolios (500+ domains)
• Geographic requirements (ccTLD restrictions)
• Risk diversification (registrar compromise)
• Service-specific needs (one registrar better for DNS, another for support)

Multi-registrar strategy:

• Primary registrar: 80% of portfolio
• Secondary registrar: 15% of portfolio
• Specialized registrars: 5% (ccTLDs, special cases)
• Never more than 3 registrars if possible

Defensive Registration Strategy

Protect brand through strategic registrations:

Defensive domains to register:

Common misspellings:

• Typos (gooogle.com for google.com)
• Character swaps (googel.com)
• Double letters (googlr.com)
• Adjacent keyboard keys (googke.com)

Alternate TLDs:

• .net (if you have .com)
• .org (non-profit confusion)
• .io (tech alternatives)
• Country codes where you operate

Hyphenated versions:

• your-company.com
• yourcom-pany.com

Common additions:

• yourcompanyinc.com
• yourcompanyltd.com
• yourcompanyusa.com
• theyourcompany.com

Cost-benefit analysis:

• Average defensive domain: $15/year
• Cybersquatting recovery: $1,500-$10,000
• Brand confusion damage: Difficult to quantify
• Customer loss from typos: Measurable opportunity cost

Defensive domain budget:

• Startup: 5-10 defensive domains ($75-150/year)
• SMB: 20-50 defensive domains ($300-750/year)
• Mid-market: 50-100 defensive domains ($750-1,500/year)
• Enterprise: 100+ defensive domains ($1,500+/year)

Security Monitoring and Alerting

Continuous Monitoring Requirements

Automated monitoring detects issues before they escalate:

Critical monitoring points:

Monitoring implementation options:

Option 1: DomainDetails Pro

• Daily WHOIS/RDAP monitoring
• Nameserver change detection
• Status code tracking
• Email alerts on changes
• Portfolio dashboard

Option 2: Custom monitoring script

# Pseudo-code for domain monitoring
import whois
import dns.resolver
from datetime import datetime

def monitor_domain(domain):
    # Check WHOIS data
    current_whois = whois.query(domain)
    previous_whois = load_previous_whois(domain)

    if current_whois != previous_whois:
        alert("WHOIS change detected", domain, current_whois)

    # Check nameservers
    current_ns = dns.resolver.resolve(domain, 'NS')
    previous_ns = load_previous_ns(domain)

    if current_ns != previous_ns:
        alert("Nameserver change detected", domain, current_ns)

    # Check status codes
    if 'clientTransferProhibited' not in current_whois.status:
        alert("Transfer lock disabled!", domain)

    # Store current state for next check
    save_current_state(domain, current_whois, current_ns)

# Run for all domains every 6 hours
for domain in portfolio:
    monitor_domain(domain)

Option 3: Enterprise monitoring platform

• Integrate with existing SIEM
• Custom alerting rules
• Correlation with other security events
• Centralized dashboard
• Compliance reporting

Alert Escalation Procedures

Ensure alerts reach right people at right time:

Alert severity classification:

Critical (P1):

• Domain transfer initiated
• Registrar lock disabled
• Nameservers changed
• Contact email changed
• Multiple failed login attempts

Response SLA: 15 minutes Notification: Page on-call engineer + security team + manager

High (P2):

• WHOIS contact data changed
• Authorization code requested
• Unusual login location
• Expiration date changed unexpectedly

Response SLA: 1 hour Notification: Email + Slack + SMS to security team

Medium (P3):

• Single failed login attempt
• Account accessed from new location (but successful auth)
• Domain approaching expiration (30 days)

Response SLA: 4 hours Notification: Email + Slack to security team

Low (P4):

• DNS record changed (expected)
• Routine configuration update
• Scheduled maintenance notification

Response SLA: 24 hours Notification: Email to relevant team

Escalation path:

Alert → On-call Engineer (15 min) → Security Lead (30 min) →
CISO (1 hour) → CTO (2 hours) → CEO (4 hours)

On-call rotation:

• 24/7 coverage for critical alerts
• Primary and backup on-call assignments
• Weekly rotation (Monday to Monday)
• Compensation for on-call duty
• Clear handoff procedures

False Positive Management

Reduce alert fatigue while maintaining security:

Common false positive sources:

• Legitimate DNS record updates
• Scheduled maintenance by IT team
• Auto-renewal processes
• Expected transfers between registrars
• Registrar system updates

False positive reduction strategies:

1. Maintenance windows:

• Declare maintenance window in advance
• Suppress alerts during maintenance window
• Require maintenance approval workflow
• Document all expected changes

2. Change authorization system:

• Log all planned changes before execution
• Compare alerts against authorized changes
• Auto-acknowledge alerts for authorized changes
• Flag unauthorized changes prominently

3. Tuning alert thresholds:

• Review false positive rate monthly
• Adjust sensitivity based on historical data
• Different thresholds for different domain tiers
• Balance security vs. operational overhead

4. Alert aggregation:

• Combine related alerts into single notification
• Suppress duplicate alerts within time window
• Daily digest for low-priority items
• Immediate notification for unique alerts

False positive review process:

Monthly Alert Review:
1. Calculate false positive rate by alert type
2. Identify top 3 false positive generators
3. Analyze root cause of false positives
4. Implement tuning to reduce false positives
5. Document changes and measure improvement
6. Repeat next month

Vendor and Third-Party Risk

Third-Party Access Management

Control vendor access to domain infrastructure:

Vendor access principles:

• Grant least privilege access
• Time-limited access only
• Audit vendor activity regularly
• Require vendor security attestations
• Include security terms in contracts
• Maintain vendor inventory

Common third-party scenarios:

Marketing agency managing DNS:

• Grant DNS management access only (not full registrar)
• Use separate DNS account with limited permissions
• Review changes weekly
• Revoke immediately when contract ends

Web development firm:

• Provide DNS records via documentation
• They configure on their hosting
• No direct registrar access
• Developer makes requests, we execute

IT managed service provider:

• Full access may be necessary
• Require MSP to use dedicated account
• 2FA mandatory
• Quarterly access review
• Activity logging and review

Domain broker or consultant:

• Never provide direct registrar access
• Act as liaison between broker and registrar
• Verify all proposed changes before execution
• Document all communications

Vendor onboarding checklist:

• Business justification documented
• Security assessment completed
• Contract includes security requirements
• Access level defined (least privilege)
• Time-limited access specified
• Vendor acknowledges security policy
• Vendor contact information collected
• Access granted and documented
• Manager notified of new vendor access

Vendor offboarding checklist:

• Contract end date identified in advance
• Access revocation scheduled
• Final deliverables received
• Access revoked on end date
• Credentials rotated if shared
• Vendor removed from access list
• Offboarding documented in audit log

Vendor Security Assessment

Evaluate third-party security before granting access:

Vendor security questionnaire:

1. Company information

   • How long in business?
   • Number of employees with domain access
   • Previous security incidents?

2. Security controls

   • Do you require 2FA for employees?
   • How are credentials stored?
   • Do you use password managers?
   • What is your password policy?

3. Access management

   • How many people will access our domains?
   • Do you use role-based access control?
   • How quickly can you revoke access?

4. Incident response

   • Do you have incident response procedures?
   • How do you notify clients of breaches?
   • What is your SLA for incident response?

5. Compliance

   • Any relevant certifications (SOC 2, ISO 27001)?
   • Do you undergo security audits?
   • Can you provide attestation reports?

Risk rating system:

API Key and Integration Security

Secure programmatic access:

API key management:

• Generate separate API key for each integration
• Use most restrictive permissions possible
• Rotate keys every 90 days
• Never commit keys to source control
• Store keys in secure secrets management system
• Monitor API usage for anomalies

API security best practices:

1. Key rotation schedule:

API Key Rotation Process:
Day 1: Generate new API key with same permissions
Day 2: Update application to use new key
Day 3: Verify application working with new key
Day 4: Revoke old API key
Day 5: Document rotation in audit log

2. Usage monitoring:

• Track API calls by key
• Alert on unusual volume
• Alert on unauthorized endpoints
• Geographic anomaly detection
• Failed authentication tracking

3. Key compromise response:

API Key Compromise Response:
1. Revoke compromised key immediately (within 15 minutes)
2. Generate new key with different value
3. Update legitimate applications
4. Audit recent API activity
5. Investigate compromise source
6. Document incident
7. Implement additional controls

• Ready to promote secondary to primary if needed
• Example: primary at Cloudflare, secondary at Namecheap

Secondary DNS provider:

• Configure hidden primary/secondary DNS architecture
• Automatic failover if primary DNS unavailable
• Regular synchronization verification
• Different provider than primary (avoid common mode failure)

DNS record backups:

• Automated daily DNS zone backups
• Store in secure, separate location
• Test restoration quarterly
• Maintain historic versions (30+ days)

Documentation backups:

• Domain inventory stored in multiple locations
• Credentials in password manager with backup
• Recovery procedures printed and stored securely
• Regular review to ensure current

Succession Planning

Prevent single points of failure:

Bus factor analysis: "What happens if our domain administrator is hit by a bus?"

Mitigation strategies:

• Document all procedures (assume reader has no prior knowledge)
• Cross-train multiple employees
• Maintain current documentation
• Regular knowledge transfer sessions
• Backup contacts for all critical functions

Knowledge transfer program:

Domain Management Succession:

Primary Administrator: [Name]
Backup Administrator: [Name]
Emergency Contact: [Name]

Quarterly Knowledge Transfer:
- Primary trains backup on recent changes
- Backup performs audit under supervision
- Both review and update documentation
- Test backup's ability to execute procedures

Annual Full Handoff Simulation:
- Primary takes week off
- Backup performs all routine tasks

Frequently Asked Questions

How much should a business budget for domain security?

Budget depends on portfolio size and criticality. Minimum: $500-1,000/year for small business (2FA, monitoring, registry lock on primary domain). Mid-market: $5,000-15,000/year (enterprise registrar, comprehensive monitoring, multiple registry locks). Enterprise: $25,000-100,000+/year (dedicated support, advanced security, full portfolio management). Remember, a single domain theft can cost $100,000-$1M+ in recovery and lost revenue—security spending is insurance that pays for itself many times over.

What's the biggest security mistake businesses make?

Not enabling two-factor authentication. 2FA prevents 99% of automated attacks and most manual attacks. Even businesses that understand domain importance often skip 2FA, thinking their password is "strong enough." It's not. The second biggest mistake is treating domain management as an afterthought—no documentation, no monitoring, no policies. Treat domains like the critical business assets they are.

Should we use the same registrar for all domains?

Generally yes, for portfolio management efficiency and security consistency. Consolidation simplifies access control, monitoring, and security policy enforcement. However, very large enterprises (500+ domains) sometimes use 2-3 registrars for risk diversification. The key is never to use more than 3 registrars total—beyond that, management overhead outweighs any benefits.

How do we handle domain security for acquired companies?

Domain acquisition should be part of M&A due diligence. Immediately upon acquisition: audit all domains, transfer to your registrar (or preferred M&A registrar), enable all security controls, integrate into monitoring, update contact information, verify no pending disputes or legal issues. Many acquirers discover domain issues post-acquisition when it's much harder to resolve. Make domain transfer part of day-one integration activities.

What's the ROI of registry lock?

Registry lock costs $100-1,500/year per domain but prevents unauthorized transfers even if your registrar account is fully compromised. Compare this to domain theft recovery costs ($50,000-500,000+) and business disruption costs (potentially millions). For any domain generating more than $10,000/year in value (revenue, brand equity, customer access), registry lock ROI is clear. For your primary business domain, registry lock should be non-negotiable.

How many people should have domain admin access?

Minimum two (primary and backup), maximum five. More than five creates too much exposure and makes access management difficult. Use role-based access to give people appropriate permissions without full admin access. For large organizations, consider: 2 admins (can do everything), 3-5 managers (can modify but not transfer), unlimited viewers (read-only). Regularly audit who has what access.

What happens if our domain administrator leaves the company?

This is why documentation and backup access are critical. Before they leave: knowledge transfer to backup admin, update all shared documentation, verify backup admin has working credentials and 2FA. Upon departure: immediately revoke their access, rotate any shared credentials (there shouldn't be any, but verify), review recent activity for suspicious actions, update contact information if they were primary contact. Have backup admin perform full audit to ensure nothing overlooked.

Should we self-host DNS or use a provider?

Use a reputable DNS provider (Cloudflare, Route 53, NS1, Dyn) unless you have dedicated DNS expertise. Self-hosted DNS requires: redundant infrastructure, DDoS protection, 24/7 monitoring, security patching, high availability design. Most businesses don't have this expertise in-house. Major DNS providers offer better uptime, security, and performance than most self-hosted solutions. Focus your team on your core business, not DNS infrastructure.

How do we handle domain security across multiple countries?

Challenge with country-code TLDs (ccTLDs): each has different registrars, rules, and security features. Strategy: centralize management through a registrar with ccTLD support (MarkMonitor, CSC, GoDaddy), implement consistent security policies across all TLDs (2FA, monitoring, documentation), document unique requirements for each ccTLD, establish local contacts for regions where your IT team isn't fluent in language/culture. Some ccTLDs have mandatory local presence requirements—work with registrar to ensure compliance.

What insurance covers domain theft?

Standard business insurance usually doesn't cover domain theft. Cyber liability insurance sometimes does—check your policy specifically. Coverage varies: some policies cover recovery costs, some cover business interruption, few cover ransom payments (and paying ransom not recommended anyway). Even with insurance, prevention is far better than dealing with claims process during crisis. Don't rely on insurance as primary protection—use it as backup after implementing strong security controls.

Key Takeaways

• Domain security is business continuity—a compromised domain can halt all operations instantly, making domain security as critical as physical security

• Two-factor authentication is non-negotiable—enable on all registrar accounts without exception; it prevents 99% of account compromises

• Layer security controls—combine 2FA, domain locks, registry locks, monitoring, and access controls for defense-in-depth strategy

• Human factors are the weakest link—invest in employee training, security awareness, and phishing resistance; most breaches exploit people, not technology

• Access management prevents insider threats—implement role-based access, separation of duties, and immediate offboarding to minimize risk

• Monitoring enables rapid response—automated monitoring detects unauthorized changes before they escalate into full compromise

• Incident response planning is essential—documented procedures, clear roles, and regular testing ensure effective response when seconds count

• Document everything—comprehensive documentation enables recovery, satisfies compliance, and prevents single points of failure

• Third-party risk requires management—vendors with domain access extend your attack surface; assess, control, and audit vendor security

• Prevention is exponentially cheaper than recovery—comprehensive domain security costs thousands; recovery from compromise costs hundreds of thousands to millions
