In our dynamic world, the field of software development continues to evolve and grow to align with modern technologies and demands. Enterprises consistently provide new functionality and updates to ensure customer satisfaction. This rapid evolution process is known as DevOps. However, as we run faster, we face new threats. When security is not considered at the initial stage, the door to vulnerabilities and data leaks can easily open.
The concept of DevSecOps aims at integrating security into every phase of the software development lifecycle. Consequently, the continuous monitoring of security is carried out during development. In this blog, we will discuss the fundamentals of DevOps security and provide some easy tips to ensure that your application stays protected.
1. What does “Shift Left” mean, and what makes it essential?
Previously, security was a sort of final test for an automobile before its shipment to dealerships. If a defect was detected during the test, then the whole assembly line had to stop.
The phrase "Shift Left" stands for implementing security practices during the early phases of product development.
What advantages does this strategy offer?
- It is cost-efficient: Resolving an issue related to security at the stage of code writing saves companies a lot of money compared to correcting the problem once the program is operational
- It increases efficiency: When developers incorporate security into their workflow, last-minute issues do not delay product deployment.
- It yields more secure code: Developers become proficient in writing secure code as early as possible, which positively impacts the overall system's safety.
2. Using Automation for Early Detection of Issues:
The best feature of DevOps, which allows us to automate everything, can be used for detecting security problems early on. Automation allows us to set up tests that run every time the code is changed. We do not have to have a human expert reviewing every single line of code manually anymore.
There are three types of automated testing:
- Static Tests (SAST): The name implies that these tests are going to be executed when your code is not running yet. It is more like a spell checker, but for security bugs. Commonly, it detects such issues as forgotten passwords, bad encryption, and so on.
- Dynamic Tests (DAST): These are tests that work by executing the program. They simulate attacks from hackers and try to break your app in order to detect the vulnerabilities.
- Dependency Scanning: As almost any program requires some third-party libraries in order to work, these tools will help you understand if those libraries have any existing security flaws
3. Securing your Software Supply Chain:
Software development isn't always about your own source code. You use a group of tools, servers, and code libraries when developing an application and that makes up your Software Supply Chain.
Similar to how food businesses must know the exact components of their products to ensure that they are all safe, software businesses also need to be aware of everything inside their application. In fact, one solution is creating a Software Bill of Materials (SBOM) to list down all of the components in detail to allow for easy identification of security flaws.
4. Managing Secrets and Identities:
In the world of software development, "secrets" include passwords, API keys, and private tokens. If an attacker gets access to your secrets, then the attacker will gain full control over your systems.
Secret management best practices:
- Do not hide passwords in your source code: This is the biggest mistake. Putting passwords in your code means that everyone with access to the source code knows your password.
- Use a digital safe: Use tools referred to as "Secret Management" which store your secrets in a digital safe. The code asks for the password only when needed.
- Control who can do what: Limit permissions for both users and automation to the minimum required for a task.
5. Security Is a Team Sport: Creating the Right Culture:
Security is less about the technology itself than about the culture and mindset. You cannot entrust the role of the "Security Person," and everyone, from developers to managers and testers, must think about security.
How to develop a security culture:
- Education: Provide developers with straightforward education about avoiding basic security traps.
- Security Champions: Choose Security Champions for each development team. These experts will help other members of the team and keep security high among everybody's priorities.
- No-Blame Reviews: If a security violation occurs, do not search for someone to blame. The main thing is to fix the system so that the same error will not occur again.
6. Watching Over Your Software (Monitoring):
The security measures should not stop when the product is released. Continuous Monitoring and Observability are needed to control how the software behaves in the real-world environment.
Through monitoring, any irregularities may become apparent – e.g., a sudden increase in login attempts or unauthorized access attempts to certain parts of the system. The quicker you spot these problems, the faster you'll manage to address them before they turn out to be too damaging.
DevSecOps security measures may seem difficult to comprehend and perform initially, but in reality, they're quite intuitive. You do not have to be a security specialist to ensure the protection of your project. Just follow the principles of shifting left, automation, and collaboration to obtain both speed and safety.
