Continuous Integration/Continuous Delivery (CI/CD) environments are the bedrock for organizations seeking to streamline software development and deployment. However, as the adoption of CI/CD environments escalates, the call for robust security measures to defend against potential threats is becoming louder. In this light, the National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) have launched a comprehensive guide on Defending CI/CD Environments, offering key insights and guidance for securing these environments.
Key Threats to CI/CD
Insecure code
In the realm of CI/CD, insecure code signifies code containing vulnerabilities or weaknesses that can be exploited by threat actors. Such code can include poorly written segments, code that bypasses secure coding standards, or code not adequately scrutinized for security vulnerabilities. These loopholes can trigger a plethora of security problems, including data breaches, system compromise, and unauthorized exposure of sensitive information.
Poisoned pipeline execution
Poisoned pipeline execution embodies a threat scenario where an attacker injects malicious code into the pipeline, subsequently executed during the build or deployment process. This infiltration can lead to the rollout of compromised software or the exfiltration of sensitive data, causing extensive damage if not promptly tackled.
Insufficient pipeline access controls
Insufficient pipeline access controls pose a security threat when the necessary safeguards restricting pipeline access are missing. This loophole could allow unauthorized modification or deletion of pipeline components, jeopardizing the pipeline's integrity and the developed software's security.
Exposure of secrets
Exposure of secrets refers to the risk of sensitive information, such as passwords, API keys, and credentials being accessed by unauthorized individuals. This could occur due to insecure storage or transmission of secrets or lack of adequate access controls.
Cybersecurity Best-Practices for Protecting CI/CD
Integrate Security Scanning and Vulnerability Management into the CI/CD Pipeline
To safeguard your CI/CD pipeline, incorporate automated security testing tools to scan code for vulnerabilities during the build process. However, simply detecting vulnerabilities is not enough. Implement a robust vulnerability management mechanism, which includes proper tracking, remediation, and validation of fixes.
