How hardening servers with DevSecOps and security as code

Ensure that servers are secure in production is crucial for reliable infrastructure. DevSecOps shift this concern to the left in the pipeline to improve teams' communication and awareness of security issues. However, hardening servers is a task far from trivial, and a tool like Operous can help.

What is DevSecOps?

DevSecOps imply the integration of security in a current DevOps software delivery flow. However, it does not mean that the concern with an application or server security will occur only in a pre-release or, even worse, only after the software is in production. DevSecOps encourages developers and sysadmins to move security from the right to the left (analysis and development phases) of their delivery flow or pipeline.

What is hardening?

All the software security ambit is broad, and DevSecOps is not a security tool that can easily plug in your pipeline to solve all issues. However, hardening servers can be the right start to improve and reach a reliable infrastructure. Hardening will reduce the surface of vulnerabilities by spotlighting elevated privileges, known vulnerabilities, and weak credentials.

How infrastructure and security as code can help?

With security as a code approach, developers can include security checks for hardening servers directly into the current development workflow. This code will be versioned and integrated into a pipeline to ensure security compliance in servers where the application is running. The security as a code will lead to a resilient history and documentation about the best practices developers are applying.

How assess security problems on servers and start hardening?

To help hardening servers, CIS Benchmarks have a great collection of best-practice security configurations, but configure and check for multiples servers continuously is a burdensome task.

Operous come in handy to be easily plugged in pipelines assessing servers continuously during integrations and deployments with already created test suits for software like Docker and Nginx and bring freedom to teams build and manage their test suits.
