DevSecOps stands for Development, Security, Operations, and the goal of this development approach is to integrate security into every stage of the software development and operations lifecycle, rather than consigning it to the Testing phase of the software development lifecycle (SDLC).
The DevSecOps movement is coming to prominence due to the growing costs of vulnerabilities in production software. In 2021, the number of newly discovered vulnerabilities increased over the previous year, and 2022 is on track to beat 2021’s numbers. These vulnerabilities can be exploited to breach sensitive data, infect systems with malware, or achieve other malicious goals.
The later that a vulnerability is detected in the SDLC, the greater the cost to the organization. Some estimates put the cost of fixing a vulnerability in production as 100x higher than if the same potential vulnerability was identified and addressed in the Requirements stage of the SDLC.
DevSecOps is designed to reduce these costs and risks. By “shifting security left” or integrating security earlier into the SDLC, companies can reduce the cost of remediation. Additionally, identifying vulnerabilities before they reach production reduces the probability of expensive, damaging security incidents.
DevOps practices are designed to speed and streamline development processes through collaboration and automation. By creating a tighter integration between development and operations teams, shortening development cycles, and automating where possible, DevOps provides significant benefits compared to traditional development methodologies.
DevSecOps differs from DevOps in that it brings the security team into this collaboration earlier in the SDLC. In the past, security was largely relegated to the Testing phase of the SDLC, when development was largely complete and the cost of fixing problems was high. Integrating security from the start reduces the cost of remediating vulnerabilities and improves the chances that security is integrated, rather than “bolted on”.
Implementing DevSecOps requires implementing very different processes and philosophies than traditional development methodologies. Some best practices that can help to improve the success of a DevSecOps program include:
Adopting the mindsets and philosophies of DevSecOps is an important step towards shifting security left. However, a DevSecOps program is only effective if developers and security personnel have access to the right tools.
Some of the key tools that can dramatically improve the effectiveness of a DevSecOps program include:
Simply having these tools is not enough. Organizations also need to integrate these solutions into their automated CI/CD pipelines, train developers on their use, and ensure that processes are regularly audited to ensure that they are both effective and secure against modern threats.
Culture is essential to the success of a DevSecOps program. One of the main reasons why security is often relegated to the Testing stage of the SDLC is that manual security processes can slow down development processes. For development teams where an on-time release is the top priority, security can be seen as a burden and a roadblock to success.
The first step in building a successful DevSecOps culture is getting the development and operations teams on board. Properly implemented, security can be an enabler to DevOps success, not an inhibitor. By eliminating vulnerabilities early in their lifecycles, DevSecOps reduces the time and costs associated with fixing them.
An effective DevSecOps program has security champions in each team and in management. This approach ensures that each team has the resources that it needs to do its job, and management support empowers the security champions to fulfill their role.
DevSecOps with CloudGuard
Implementing DevSecOps can improve the quality and security of an organization’s applications. Building security into code from the start reduces the cost of fixing potential issues and ensures that security is integrated into the design rather than bolted on at the end.
An effective DevSecOps program is one where the team is empowered and has the tools that they need to effectively build security into their processes. Check Point CloudGuard provides the capabilities that development teams need to implement DevSecOps in the cloud, including:
Access to the right tools is essential to the success of a DevSecOps program. Learn more about what to look for in this buyer’s guide to cloud DevSecOps solutions. Then, learn how CloudGuard can improve your cloud DevSecOps processes by signing up for a free demo today.
