Event: denial_of_service_tools

Quick Explanation

The denial_of_service_tools recipe identifies the execution of Denial-of-Service (DoS) tools. In the context of a CI/CD pipeline, code changes that trigger this detection may indicate the introduction of DoS capabilities, posing risks of service disruption and legal issues.

  1. Description: Denial-of-Service (DoS) tools
  2. Category: Impact
  3. Method: Network Denial of Service
  4. Importance: Critical

Analysis of the Event

This detection event is triggered by the execution of various Denial-of-Service (DoS) attack tools, which are typically used to overwhelm a system or network with traffic, rendering it inaccessible to legitimate users. This detection is crucial as it indicates an attempt to disrupt services, potentially causing significant business impact.

The detection mechanism is execution-based, monitoring for the execution of specific files associated with known DoS tools. These tools span multiple categories, including application layer attacks, transport layer attacks, reflection/amplification attacks, botnets, other DDoS methods, and fragmentation-based attacks.

The critical importance level assigned to this event underscores the significant threat posed by DoS attacks. Successful execution could lead to service disruption and potential data loss or corruption.

Implications for the CI/CD Pipeline

If a pull request introduces code changes that trigger this detection event, it suggests a possible attempt to incorporate DoS attack capabilities into the application being developed. If such code changes are merged and deployed in a production environment, they could be exploited to launch DoS attacks against internal systems or even third-party systems if the application interacts with external networks.

This could lead to severe consequences, including service disruption, reputational damage due to non-compliance with cybersecurity best practices, and potential legal implications if third-party systems are affected.

  1. Review Pull Requests: Thoroughly review any code changes related to file executions.
  2. Check Dependencies: Investigate any dependencies or libraries that might be associated with known DoS tools.
  3. Examine Network Patterns: Analyze any new network communication patterns introduced by the pull request.
  4. Consult Developers: Discuss with the developer who submitted the pull request to clarify the need for these changes.
  5. Conduct Risk Assessment: If the changes are necessary, perform a comprehensive risk assessment and implement additional monitoring to detect potential abuse.
  6. Reject Unnecessary Changes: If the changes are not necessary or cannot be justified, reject the pull request and advise the developer to remove any code related to DoS tools.
