ZeroTrustKerberosLink Vulnerability Management Plan

Overview

ZeroTrustKerberosLink implements a comprehensive vulnerability management program to identify, classify, remediate, and prevent security vulnerabilities. This document outlines our structured approach to security testing, vulnerability management, and remediation processes that support our security hardening initiatives.

Security Testing Framework

Testing Methodology

Our security testing framework follows a multi-layered approach:

  1. Automated Security Scanning
  2. Static Application Security Testing (SAST)
  3. Dynamic Application Security Testing (DAST)
  4. Software Composition Analysis (SCA)
  5. Container security scanning
  6. Infrastructure-as-Code scanning

  7. Manual Security Testing

  8. Code reviews with security focus
  9. Architecture reviews
  10. Threat modeling sessions
  11. Manual penetration testing

  12. Continuous Security Validation

  13. CI/CD pipeline integration
  14. Pre-commit and pre-merge security hooks
  15. Automated security regression testing

Testing Frequency

Test Type Frequency Scope
SAST Every commit All code changes
DAST Weekly Production-equivalent environment
SCA Daily All dependencies
Penetration Testing Quarterly Full application
Red Team Exercise Annually Full system and infrastructure

Vulnerability Classification

Severity Levels

ZeroTrustKerberosLink uses the following severity classification based on the Common Vulnerability Scoring System (CVSS):

Severity CVSS Score Description
Critical 9.0 - 10.0 Vulnerabilities that can be easily exploited and result in system compromise without requiring user interaction
High 7.0 - 8.9 Vulnerabilities that can be exploited to compromise sensitive data or system integrity
Medium 4.0 - 6.9 Vulnerabilities that may be more difficult to exploit but could still lead to some compromise of the system
Low 0.1 - 3.9 Vulnerabilities that are extremely difficult to exploit and provide minimal access or information disclosure

Impact Assessment

Each vulnerability is assessed based on:

  1. Exploitability: How easily can the vulnerability be exploited?
  2. Affected Components: Which system components are impacted?
  3. Data Sensitivity: Does the vulnerability expose sensitive data?
  4. Authentication Bypass: Does the vulnerability bypass authentication controls?
  5. Business Impact: What is the potential business impact if exploited?

Remediation Process

Remediation Timelines

Severity Remediation Timeline Notification Timeline
Critical 24 hours Immediate
High 7 days 24 hours
Medium 30 days 7 days
Low 90 days 30 days

Remediation Workflow

  1. Identification: Vulnerability is identified through testing or reporting
  2. Validation: Security team validates the vulnerability
  3. Classification: Vulnerability is classified by severity and impact
  4. Assignment: Vulnerability is assigned to the appropriate team
  5. Remediation: Fix is developed and tested
  6. Verification: Security team verifies the fix
  7. Deployment: Fix is deployed to production
  8. Documentation: Vulnerability and fix are documented

Exception Process

In cases where vulnerabilities cannot be remediated within the standard timeline:

  1. Exception Request: Team requests an exception with justification
  2. Risk Assessment: Security team assesses the risk of delayed remediation
  3. Mitigation Plan: Temporary mitigations are implemented
  4. Approval: Exception is approved or denied by security leadership
  5. Documentation: Exception is documented with expiration date
  6. Tracking: Exception is tracked and reviewed regularly

Vulnerability Disclosure

Responsible Disclosure Policy

ZeroTrustKerberosLink maintains a responsible disclosure policy that:

  1. Provides a secure method for reporting vulnerabilities
  2. Acknowledges receipt within 24 hours
  3. Provides regular updates on remediation progress
  4. Recognizes security researchers who responsibly disclose issues
  5. Does not pursue legal action against good-faith security research

Customer Notification

Severity Customer Notification Approach
Critical Immediate notification with mitigation guidance
High Notification within 72 hours of validation
Medium Notification with next release notes
Low Listed in security portal

Penetration Testing Methodology

  1. Reconnaissance: Gathering information about the target
  2. Scanning: Identifying potential vulnerabilities
  3. Vulnerability Analysis: Determining exploitability
  4. Exploitation: Attempting to exploit vulnerabilities
  5. Post-Exploitation: Determining impact of successful exploits
  6. Reporting: Documenting findings and recommendations

Security Monitoring and Reporting
