- Effective DevOps ensures rapid and frequent development cycles (sometimes weeks or days), but outdated security practices can undo even the most efficient DevOps initiatives. Now, in the collaborative framework of DevOps, security is a shared responsibility integrated from end to end.

Sep 7, 2023 · All of the above is why it’s critical to operationalize DevSecOps — the idea that cloud security is a shared responsibility between developers, security teams, and operations teams — across your organization.
Jul 12, 2024 · Security Engineer: In the DevOps world, security is not an afterthought. Security engineers work hand-in-hand with developers to integrate security measures into the development process. They implement security best practices, conduct vulnerability assessments, and respond to security incidents.

Security is a key part of DevOps. But how does a team know if a system is secure? Is it really possible to deliver a completely secure service?
Unfortunately, the answer is no. DevSecOps is a continuous and ongoing effort that requires the attention of everyone in both development and IT operations. While the job is never truly done, the practices that teams employ to prevent and handle breaches can help produce systems that are as secure and resilient as possible.
Teams that don't have a formal DevSecOps strategy are encouraged to begin planning as soon as possible. At first there may be resistance from team members who don't fully appreciate the threats that exist. Others may not feel that the team is equipped to face the problem and that any special investment would be a wasteful distraction from shipping features. However, it's necessary to begin the conversation to build consensus as to the nature of the risks, how the team can mitigate them, and whether the team needs resources they don't currently have.
Expect skeptics to bring some common arguments, such as:
•How real is the threat? Teams often don't appreciate the potential value of the services and data they're charged with protecting.
•Our team is good, right? A security discussion may be perceived as doubt in the team's ability to build a secure system.
•I don't think that's possible. This is a common argument from junior engineers. Those with experience usually know better.
•We've never been breached. But how do you know? How would you know?
Security strategy components
There are many techniques that can be applied in the quest for more secure systems. Every team should already have at least some practices in place for preventing breaches. Writing secure code has become more of a default, and there are many free and commercial tools to aid in static analysis and other security testing features. However, many teams lack a strategy that assumes system breaches are inevitable. Assuming that you've been breached can be hard to admit, especially when having difficult conversations with management, but that assumption can help you answer questions about security on your own time. You don't want to figure it all out during a real security emergency. Common questions to think through include: •How will you detect an attack? •How will you respond if there is an attack or penetration? •How will you recover from an attack, such as when data has been leaked or tampered with?
Key DevSecOps practices
There are several common DevSecOps practices that apply to virtually any team. First, focus on improving mean time to detection and mean time to recovery. These metrics indicate how long it takes to detect a breach and how long it takes to recover, respectively. They can be tracked through ongoing live site testing of security response plans. When evaluating potential policies, improving these metrics should be an important consideration. Practice defense in depth. When a breach happens, attackers can get access to internal networks and everything inside them. While it would be ideal to stop attackers before it gets that far, a policy of assuming breaches drives teams to minimize exposure from an attacker who has already gotten in. Finally, perform periodic post-breach assessments of your practices and environments. After a breach has been resolved, your team should evaluate the performance of the policies, as well as their own adherence to them. Policies are most effective when teams actually follow them. Every breach, whether real or practiced, should be seen as an opportunity to improve.
There are too many threats to enumerate them all. Some security holes are due to issues in dependencies like operating systems and libraries, so keeping them up-to-date is critical. Others are due to bugs in system code that require careful analysis to find and fix. Poor secret management is the cause of many breaches, as is social engineering. It'...
A common practice at Microsoft is to engage in war game exercises. These are security testing events where two teams are tasked with testing the security and policies of a system.
The red team takes on the role of an attacker. They attempt to model real-world attacks in order to find gaps in security. If they can exploit any, they also demonstrate the potential impact of their breaches.

DevSecOps introduces security to the DevOps practice by integrating security assessments throughout the CI/CD process. It makes security a shared responsibility among all team members who are involved in building the software.
Security engineers are responsible for integrating security and best practices into the DevOps pipeline. Additionally, they collaborate with development and operations teams to conduct security assessments, vulnerability scans, and compliance checks.
The DevSecOps framework includes continuous integration, continuous delivery, and continuous security. It is a method by which security, operations, and security teams work together and share the responsibility for quickly delivering quality software, while reducing security vulnerabilities.
