Threat Model Analysis for nationalsecurityagency/skills-service

Threat: Weak Skills-Service Authentication

  • Description: Attacker might use brute-force attacks, dictionary attacks, or exploit known vulnerabilities in outdated authentication mechanisms used by skills-service to gain unauthorized access to skills data.
    • Impact: Unauthorized access to sensitive skills data, potential data breaches, manipulation of skills information, account takeover.
    • Affected Component: Skills-Service Authentication Module
    • Risk Severity: High
    • Mitigation Strategies:
      • Enforce strong password policies within skills-service if it manages users.
      • Implement multi-factor authentication for skills-service access if applicable.
      • Regularly review and update authentication mechanisms to follow security best practices.
      • Integrate with a robust and secure identity provider if possible.

Threat: Skills-Service Authorization Bypass

  • Description: Attacker might exploit flaws in the skills-service API authorization logic to access or modify skills data without proper permissions. This could involve manipulating API requests, exploiting IDOR vulnerabilities, or privilege escalation.
    • Impact: Unauthorized data access, modification, or deletion. Potential for data corruption and unauthorized actions within the skills management system.
    • Affected Component: Skills-Service API Authorization Logic, API Endpoints
    • Risk Severity: High
    • Mitigation Strategies:
      • Implement robust and granular role-based access control (RBAC) within skills-service.
      • Thoroughly test API endpoints for authorization vulnerabilities using penetration testing and code review.
      • Validate user permissions on every API request and resource access.
      • Follow the principle of least privilege when designing authorization rules.

Threat: Insecure Skills-Service Session Management

  • Description: Attacker might exploit session management vulnerabilities like session fixation or hijacking to gain unauthorized access to a legitimate user's session within skills-service. This could be achieved through network sniffing, cross-site scripting (XSS) if present, or session token manipulation.
    • Impact: Account takeover, unauthorized actions performed under a legitimate user's session, data breaches.
    • Affected Component: Skills-Service Session Management Module
    • Risk Severity: High
    • Mitigation Strategies:
      • Use strong, cryptographically secure session tokens.
      • Implement HTTP-only and Secure flags for session cookies.
      • Implement session timeouts and automatic logout after inactivity.
      • Protect against session fixation and hijacking attacks.
      • Consider using short-lived access tokens instead of long-lived session cookies.

Threat: Skills-Service API Injection Vulnerabilities

  • Description: Attacker might inject malicious code (e.g., SQL, NoSQL, command injection) into skills-service API parameters. This could allow them to execute arbitrary commands on the server, access or modify the database, or bypass security controls.
    • Impact: Data breaches, data modification or deletion, potential for remote code execution on the skills-service server, complete system compromise.
    • Affected Component: Skills-Service API Endpoints, Data Processing Logic
    • Risk Severity: Critical
    • Mitigation Strategies:
      • Implement strict input validation and sanitization on all API endpoints.
      • Use parameterized queries or prepared statements to prevent SQL injection.
      • Avoid dynamic query construction.
      • Follow secure coding practices to prevent other injection vulnerabilities (e.g., command injection, LDAP injection).
      • Use a Web Application Firewall (WAF) to detect and block injection attempts.

Threat: Insecure Skills-Service Data Storage

  • Description: Attacker who gains access to the skills-service database or storage system (e.g., through compromised credentials, infrastructure vulnerability) could access sensitive skills data if it is not properly secured. This includes plaintext storage or weak encryption.
    • Impact: Data breaches, exposure of sensitive information, compliance violations.
    • Affected Component: Skills-Service Database, Data Storage Layer
    • Risk Severity: High
    • Mitigation Strategies:
      • Encrypt sensitive data at rest using strong encryption algorithms.
      • Implement robust access controls to the database and storage systems.
      • Regularly audit database security configurations.
      • Consider data masking or tokenization for sensitive data where appropriate.

Threat: Vulnerable Skills-Service Dependencies

  • Description: Attacker might exploit known vulnerabilities in third-party libraries and dependencies used by skills-service. This could be done by targeting publicly known vulnerabilities or discovering zero-day vulnerabilities.
    • Impact: Compromise of skills-service, leading to data breaches, denial of service, or other security issues, depending on the vulnerability.
    • Affected Component: Skills-Service Dependencies, Third-Party Libraries
    • Risk Severity: High
    • Mitigation Strategies:
      • Regularly scan skills-service dependencies for known vulnerabilities using Software Composition Analysis (SCA) tools.
      • Keep dependencies updated to the latest secure versions.
      • Monitor security advisories related to the dependencies used by skills-service.
      • Implement a process for patching vulnerabilities in dependencies promptly.

Threat: Skills-Service Supply Chain Attack

  • Description: Attacker might compromise the skills-service project itself or its dependencies through a supply chain attack. This could involve injecting malicious code into the codebase or build pipeline, which would then be distributed to users of skills-service.
    • Impact: Compromise of your application through backdoors or malicious functionality introduced via the skills-service supply chain, widespread impact if the compromised component is widely used.
    • Affected Component: Skills-Service Codebase, Build Pipeline, Distribution Channels
    • Risk Severity: High to Critical
    • Mitigation Strategies:
      • Use trusted sources for obtaining skills-service and its dependencies (e.g., official repositories).
      • Verify the integrity of downloaded packages using checksums or digital signatures.
      • Implement security scanning and monitoring of the skills-service codebase and its dependencies.
      • Consider using dependency pinning to control dependency versions and reduce the risk of unexpected changes.

Threat: Skills-Service API Endpoint Vulnerabilities (General)

  • Description: Attacker might exploit various API endpoint vulnerabilities beyond injection, such as improper error handling leading to information disclosure, insecure API design (e.g., mass assignment), or lack of rate limiting.
    • Impact: Information leakage, denial of service, or exploitation of API logic flaws, potentially leading to unauthorized actions or data manipulation.
    • Affected Component: Skills-Service API Endpoints, API Design
    • Risk Severity: High
    • Mitigation Strategies:
      • Conduct thorough API security testing, including fuzzing, penetration testing, and code review.
      • Implement proper error handling that avoids revealing sensitive information.
      • Follow secure API design principles (e.g., input validation, output encoding, rate limiting).
      • Use API security best practices and frameworks.

Threat: Insecure Skills-Service Deployment Configuration

  • Description: Attacker might exploit insecure deployment configurations of skills-service, such as exposed management interfaces, default credentials, running with excessive privileges, or insecure network configurations, to gain unauthorized access to the server or the application.
    • Impact: Unauthorized access to the skills-service infrastructure, potential for system compromise, data breaches, denial of service.
    • Affected Component: Skills-Service Deployment Environment, Infrastructure Configuration
    • Risk Severity: High
    • Mitigation Strategies:
      • Follow secure deployment practices for skills-service.
      • Harden the operating system and infrastructure where skills-service is deployed.
      • Change default credentials for all services and accounts.
      • Disable unnecessary services and ports.
      • Implement network segmentation and firewalls to restrict access to skills-service.
      • Regularly audit deployment configurations for security vulnerabilities.
