DevSecOps is a term that describes the blending of security and DevOps. It uses a concept called ‘security in layers in the DevOps world,’ which ensures each layer has a control and prevents something terrible from happening. Using this approach, you can think less about your security and focus more on developing your business.
Sites like sonraisecurity.com/who-we-serve/devsecops/ help to explore the concept better. Each layer is independent of the other, and each layer or level checks for different security concerns. If one fails or is breached, it never means that your whole system is getting compromised. In this manner, the system manages and secures your system seamlessly. What DevSecOps does is take this a step further by automating many of these tasks.
What Are the Security Levels in Your DevOps Structure?
There are five layers to a security strategy. Each one is responsible for different tasks. Yet, they all work together to keep your system secure.
The first layer contains the following:
- Application Security – The team takes care of your software development life cycle (SDLC). This layer will test your application from start to finish for vulnerabilities.
- Infrastructure Security – The team is responsible for your network, intrusion detection, and virtual private networks (VPNs).
- Platform Security – The team makes sure your OS and hardware are up-to-date and secure.
- Operations Security – The team responsible for your firewalls, user management, and access controls.
- Third-Party Security – Issues like user management, cloud provider access, and licensing fall under this category. The team will ensure these standards (and more) are followed when dealing with third parties.
- Compliance – The people who make sure you’re doing the right thing for regulatory purposes.
While every layer is essential, the second and third layers are critical. The second layer is where your data is stored, and the third layer is where your applications run. The fourth layer is vital for maintaining your systems once they’re in place. The fifth layer deals with any issues that come up outside of your central system.
How Does DevSecOps Fit into This Framework?
According to an IBM report, remote work during COVID-19 increased data breach costs in the United States by $137,000. DevSecOps is a way to automate many of the security breaches in the following ways:
- Automated Scanning – It will test your applications for vulnerabilities as they’re being developed. It allows your team to focus on growing your business instead of worrying about security.
- Automated Provisioning – It will make sure your systems are set up securely and that the correct security patches are applied.
- Automated Testing – It will make sure your systems are tested for vulnerabilities regularly.
- Automated Pen Testing – It is similar to automated testing, but it is a much more high-level and robust method.
- Continuous Monitoring – Once the security system is in place, you can regularly monitor it to ensure no security breaches or vulnerabilities need fixing.
- Continuous Integration – Proactive measures like this will ensure your systems are always up-to-date with the latest security patches.
- Automated Remediation – If a vulnerability is found, DevSecOps can automatically correct it.
- Configuration Management – It ensures that all of your systems are configured the same way and that there’s no inconsistency regarding security.
These are just some of the ways how DevSecOps can help your business. Using these tools, you can develop your applications and leave the security to the experts. It will make your systems much easier to manage and much more secure.
How Can You Get Started with DevSecOps?
The best way to get started with DevSecOps is to begin with your developers. Ensure that your developers know about security and that they are not writing insecure code by accident. Many of the tools used for DevSecOps are already part of the development process. For example, many companies use Slack to collaborate on projects and GitHub to store code.
Since these are already in place for your developers, setting up security alerts that catch vulnerabilities or issues before they become problems is easy. For example, you can create a Slack channel for each project and send a security alert to that channel whenever a vulnerability is discovered. The team will then have an opportunity to resolve or mitigate that issue before it becomes a problem.
It gives them early notice about the vulnerability and feeds into your DevOps process because you are allowing the team to resolve these problems quickly. If they become a recurring issue, it is easy to identify whether your developers correctly address the problem.
Thus, DevSecOps is a great way to automate many of the security measures you already have in place for your DevOps process. By integrating security into your development workflow, you can reduce the amount of work your team has to do and ensure that your systems are secure from the beginning.
