DevSecOps integrates security teams and security tools directly into the software development lifecycle, leveraging DevOps automation, and efficiency to ensure that applications are tested for security during each build cycle. This promotes safety and consistency and helps to ensure that security is prioritized no lower than other quality metrics or features. But how to be Agile?
DevOps and Security
Build Security In
A central concept when building security is “shift left”, or the idea that we integrate security testing earlier within the Software Development Lifecycle (SDLC) — whose phases are typically listed from left to right, such as design, development, testing, preparation, and production. Fundamentally, we shift more resources away from production on the extreme right and put more into design, testing and development phases
Automation delivers speed, consistency, and efficiency to all players of the process. It also means it’s easier to roll back in the event of mistakes. Automation helps people get their jobs done with less hands-on work, but as automation software does the same things every time, consistency is the most conspicuous benefit.
Automation benefits other facets of software production, including reporting, metrics, quality assurance, and release management, but security testing benefits are what we are focused on in this research.
The Secure Software Development Lifecycle (S-SDLC) describes how security fits into different stages of the software development lifecycle.
Define and Architect
Reference Security Architectures
Reference security architectures exist for a variety of applications and services, including web applications, data processing applications, application identification, and access management services, streaming/event processing, messaging, and more.
OWASP Top Ten vulnerabilities may need to be mitigated by code or support for products, mapping individual threats to a specific security audit for all web applications.
Monitoring and Metrics
You need to think about what data you want to collect and build it into your CI: CD and production environments to measure how your scripts and tests performed. This means that you need to involve developers and IT staff in collecting data.
Security Design Principles
This includes, for example, temporary instances to improve patch and reduce attacker persistence, unmodified services needed to remove attack surface, configuration management, cloud deployment templates, auto-fix, task separation, development and locking quality assurance personnel out of production sources and so on.
Secure the Deployment Pipeline
The need for secure source code management, build servers, and deployment pipelines are growing. Because CI / CD pipelines offer an automatic production path, you need at least tighter access controls for these systems – especially for building servers and codes.
Because CI / CD pipelines offer an automatic production path, you need at least tighter access controls for these systems – especially for building servers and codes. Many devices provide good security through digital fingerprinting, 2FA, biometric security features, etc.
Threat modeling is often done in the design stages by developers, but can even test small code snippets.
There is a great deal of work to get environments fully automated — on servers, network configuration, applications, and so on — but it makes future efforts faster and more consistent. Most teams update their scripts to apply patches, updating settings, and build scripts for different environments.
Secure Code Repositories
Many firms keep local copies of approved libraries and make it easy to get access to these resources. Then they use a combination of composition analysis tools and scripts before code is deployed into production to ensure developers are using approved versions. This helps reduce the use of vulnerable open source.
Security in the Scrum
Their focus on smaller, focused, quickly demonstrable tasks aligns nicely. See more
Unit and functional tests not only define safety requirements but also enforce them. Most development teams use this “test-driven development” model, where the goal is to ensure functionality while avoiding unwanted results. To do this, the code is created along with the tests.
Interactive Application Security Testing
Interactive Application Security Testing (IAST) is where you analyze your application’s code, usually with a scanning tool designed for the purpose, for security vulnerabilities before you launch code into production. There are several deployment models for IAST, including desktop IDE plug-ins, tools run prior to source code commits, and embedded into QA tools.
Parallelize Security Testing
It is advisable to break down more complex applications into smaller services. It also speeds up the scanning process. Rewriting and reconfiguring test environments will greatly increase efficiency and help CI to deploy quickly.
Manual vs. Automated Deployment
Many companies execute many deployment actions through scripts but launch the scripts manually when Operations and Development resources are available to monitor the push fully. For some organizations, it is not a problem to issue fully automated updates, even several times a day.
Deployment and Rollback
The most powerful is called Blue-Green or Red-Black deployment. In these cases, the old and the new code run side by side, each on its own server. If there is an error in the new code, the system will automatically revert to the old code version. Canary testing is when a small subset of each section is directed toward the new code – if an error occurs (the canary dies), the j code is revoked. Once the new code has been corrected, the whole process will restart.
Production Security Tests
Most of the larger companies use penetration testers, and most of them use “Red Teams” to test application runtime security for errors.
Automated Runtime Security
RASP is an application security technology that embeds into an application or application runtime environment, examining requests at the application layer to detect attacks and misuse in real-time. RASP can monitor and execute protection for each attack type at several points within the application. This allows the web application request to be “played” until it becomes clear that the request was actually malicious before being blocked.
There are two standards we can call the best known: The Open Web Application Security Project (OWASP) Top Ten and the SANS Common Weakness Enumeration Top 25. Still, other lists of threats and common weaknesses are available, typically focused on specific subtopics such as CSA’s top threats to cloud computing or application security measurement.
Learn how to be agile
The goal of DevOps is fast, faster, fastest: small iterative changes that offer quick feedback. You can use manual code review or fuzz testing, of course, you need to know in which part of the process this can be used and where it is worth it.
