Securing DevOps environments for Zero Trust

Securing DevOps environments is no longer a choice for developers. Hackers are shifting left so you must implement Zero Trust principles that include verify explicitly, use least privilege access, and assume breach in DevOps environments.

This article describes best practices for securing your DevOps environments with a Zero Trust approach for preventing hackers from compromising developer boxes, infecting release pipelines with malicious scripts, and gaining access to production data via test environments.

Our Securing Enterprise DevOps Environments eBook features the following visualization of the developer, DevOps platform, and application environments along with the potential security threats for each.

Notice in the above diagram how connections between environments and to external integrations expand the threat landscape. These connections can increase opportunities for hackers to compromise the system.

Bad actors are stretching across the enterprise to compromise DevOps environments, gain access, and unlock new dangers. Attacks go beyond the typical breadth of cyber security breaches to inject malicious code, assume powerful developer identities, and steal production code.

As companies transition to ubiquitous, work-from-anywhere scenarios, they must strengthen device security. Cyber security offices may lack consistent understanding of where and how developers secure and build code. Attackers take advantage of these weaknesses with remote connection hacks and developer identity thefts.

DevOps tools are key entry points for hackers, from pipeline automation to code validation and code repositories. If bad actors infect code before it reaches production systems, in most cases, it can pass through cyber security checkpoints. To prevent compromise, ensure that your development teams are engaged with peer reviews, security checks with IDE security plugins, secure coding standards, and branch review.

Cyber security teams aim to prevent attackers from sieging production environments. However, environments have widened to include supply chain tools and products. Breach of third-party open-source tools can heighten global cyber security risks.
