Mitigation Strategies Analysis for dalance/procs

Mitigation Strategy: Principle of Least Privilege for Process Information Access

Description:

  1. Identify the absolute minimum process information fields required for each application feature.
  2. Modify code to retrieve only these necessary fields from procs, avoiding indiscriminate data fetching.
  3. Conduct code reviews to ensure adherence to least privilege and prevent unnecessary process data access.
  4. Periodically audit data access patterns to confirm ongoing compliance. List of Threats Mitigated:
  • Information Disclosure (High Severity) Impact: Significantly Reduces Information Disclosure risk. Currently Implemented: Partially implemented (frontend filtering). Missing Implementation: Backend service needs modification to fetch only required fields directly from procs.

Mitigation Strategy: Data Sanitization and Filtering of Process Information

Description:

  1. Identify sensitive process information fields (e.g., command-line arguments, environment variables).
  2. Implement sanitization functions (redaction, truncation, whitelisting/blacklisting) for these fields.
  3. Apply sanitization before displaying, logging, or transmitting process information.
  4. Thoroughly test sanitization functions for effectiveness and functionality. List of Threats Mitigated:
  • Information Disclosure (High Severity) Impact: Moderately Reduces Information Disclosure risk. Currently Implemented: Partially implemented (basic frontend sanitization of command-line arguments). Missing Implementation: Comprehensive sanitization in backend, applied to environment variables, file paths, and logs.

Mitigation Strategy: Rate Limiting Process Information Queries

Description:

  1. Identify application endpoints/features using procs for process information retrieval.
  2. Define appropriate rate limits based on usage and system capacity.
  3. Implement rate limiting mechanisms (token bucket, leaky bucket) for these endpoints.
  4. Implement error handling for rate-limited requests with informative error messages.
  5. Monitor rate limiting effectiveness and adjust limits as needed. List of Threats Mitigated:
  • Denial of Service (DoS) (Medium Severity) Impact: Moderately Reduces Denial of Service risk. Currently Implemented: Not implemented. Missing Implementation: Rate limiting middleware for API endpoints retrieving process information.

Mitigation Strategy: Resource Limits for Process Information Retrieval

Description:

  1. Set timeouts for all procs library calls to prevent indefinite blocking.
  2. Limit query depth/scope for recursive process scanning to prevent resource exhaustion.
  3. Monitor system resource usage during process information retrieval.
  4. Optimize code for efficient process information retrieval, avoiding redundancy. List of Threats Mitigated:
  • Denial of Service (DoS) (Medium Severity) Impact: Moderately Reduces Denial of Service risk. Currently Implemented: Basic network request timeouts, but not specific procs timeouts. Missing Implementation: Specific timeouts for procs calls, optimization of retrieval code, and scope limits for process tree traversal if used.

Mitigation Strategy: Asynchronous Operations for Process Information Retrieval

Description:

  1. Identify synchronous procs library calls blocking the main application thread.
  2. Refactor code to use asynchronous patterns (async/await) for procs calls.
  3. Ensure non-blocking execution of process information retrieval.
  4. Thoroughly test asynchronous implementation for functionality and responsiveness. List of Threats Mitigated:
  • Denial of Service (DoS) (Low Severity)
  • Performance Degradation (Medium Severity) Impact: Minimally Reduces DoS risk, Significantly Improves Performance and Responsiveness. Currently Implemented: Synchronous process information retrieval. Missing Implementation: Asynchronous refactoring of backend code for procs calls.

Mitigation Strategy: Regularly Update procs Dependency

Description:

  1. Use dependency management tools (cargo) to manage procs dependency.
  2. Regularly monitor for updates to procs on its repository or security advisories.
  3. Consider automated dependency update tools.
  4. Test application thoroughly after updating procs for compatibility and regressions. List of Threats Mitigated:
  • Vulnerabilities in procs (Variable Severity)
  • Supply Chain Attacks (Variable Severity) Impact: Significantly Reduces risks from procs vulnerabilities and supply chain attacks. Currently Implemented: Dependencies managed by cargo, but updates not regular. Missing Implementation: Regular dependency update process, CI/CD integration for update checks.

Mitigation Strategy: Dependency Vulnerability Scanning

Description:

  1. Choose a dependency vulnerability scanning tool (cargo audit).
  2. Integrate scanning tool into CI/CD pipeline.
  3. Automate dependency vulnerability scans on each build/commit.
  4. Set up vulnerability reporting with severity levels and remediation advice.
  5. Establish a process for promptly addressing reported vulnerabilities. List of Threats Mitigated:
  • Vulnerabilities in procs and Dependencies (Variable Severity)
  • Zero-Day Exploits (Low Severity - early detection) Impact: Significantly Reduces risks from vulnerabilities in procs and dependencies. Currently Implemented: Not implemented. Missing Implementation: Integration of cargo audit into CI/CD, vulnerability alert system, and remediation workflow.

Mitigation Strategy: Code Review and Security Audits of procs Usage

Description:

  1. Incorporate security-focused code reviews, emphasizing secure procs usage.
  2. Train developers and reviewers on procs-specific security risks.
  3. Conduct regular security audits, reviewing procs usage and mitigation effectiveness.
  4. Consider external security experts for penetration testing and audits. List of Threats Mitigated:
  • All Threats (Variable Severity)
  • Implementation Flaws (Variable Severity) Impact: Moderately to Significantly Reduces all identified threats. Currently Implemented: Code reviews, but no explicit focus on procs security. Missing Implementation: Enhanced code review process with procs security focus, regular security audits and penetration testing.
