Most organizations are implementing an integrated software development system to accelerate business growth. One such approach is using a DevSecOps model.
The DevOps model is a system of software development that focuses on collaboration between developers and IT professionals as the most efficient way to produce high-quality applications.
In this approach, those who develop software work closely with configured servers. To understand what DevSecOps is, it’s necessary to know how it relates to the DevOps model.
What Is DevSecOps?
DevSecOps involves an approach to software development that combines elements of the Agile model, which favors iterative learning over planning, with elements of the DevOps approach, which emphasizes collaboration between teams of developers and IT professionals.
This method aims to create an environment where security is integrated into the software development process rather than added as an afterthought.
Why Is It Important?
As more and more organizations adopt DevOps to improve their software’s velocity, quality, and reliability, it becomes increasingly important to ensure that security is also part of that equation.
By integrating security into the DevOps process, organizations can avoid the delays and disruptions that often occur when security issues are discovered late in the development cycle.
How Does It Work?
DevSecOps works on the principle that security should be integrated into the software development process, not added as an afterthought.
Using DevSecOps, you can create an environment where security is a part of the entire development cycle from the beginning.
In the DevSecOps model, responsibility for security is shared between developers and IT professionals. Developers are responsible for inserting secure coding practices into their code as part of the initial build. At the same time, the IT professionals must put policies and procedures in place to ensure that all team members carry out the security best practices.
While the overall responsibility may lie with the IT department, developers are responsible for adhering to the policies and procedures that have been put in place.
A collaborative environment is essential because it ensures greater security – both before products are released and after deployment, when patches are applied.
Developers need to know what constitutes “best practices” to build their code accordingly. At the same time, IT professionals are responsible for organizing the flow of information between developers, testers, and operations to ensure that all stakeholders are aware of security issues.
Best Practices To Deploy And Strengthen DevSecOps Model
In 2020, 350 cyberattacks were reported, including phishing, fraudulent websites, and direct attacks on organizations.
While there isn’t a standard model for DevSecOps, the following best practices might yield better results,
Ensure that All Stakeholders Are Aware of Security Procedures, Policies, and Expectations
Developers need to know what constitutes “best practices” to include them in their code. At the same time, IT professionals must create policies and procedures to ensure that everyone on the team follows those best practices.
Conduct Frequent Audits of the Software Development Process
In DevSecOps, audits serve as a tool for identifying gaps in security and potential areas where the software development process can be streamlined. These audits should focus on third-party components and code and documentation to ensure that it meets or exceeds security requirements.
Apply Patches Within 48 Hours of Release Whenever Possible
The traditional software development process can often take weeks or months to apply patches after a product is released.
With DevSecOps, however, that time frame is reduced to hours or days, which minimizes the window of opportunity for attackers.
Use Automated Scanning Tools to Identify Vulnerabilities
Automated scanning tools can play an essential role in the DevSecOps process by identifying vulnerabilities in code that may not be discovered through manual testing.
Companies should use automated scanning in conjunction with manual testing to ensure the most comprehensive coverage.
Implement a “Shift-Left” Strategy
In a “shift-left” strategy, security is integrated into the software development process early.
It might include using automated scanning tools to identify code vulnerabilities, establish policies and procedures for secure coding practices, and conduct security audits.
Use a “Continuous Delivery” Model
When using a continuous delivery model, code is checked in and tested multiple times as it moves through the development cycle. It helps identify potential security issues early in the process and allows for more time to address them.
Establish a Culture of Security
For the DevSecOps model to work, everyone on the project must be committed to security. It means reinforcing a culture of security through training, awareness programs, and incentives for doing so diligently.
Implement a Bug Bounty Program
When a vulnerability is discovered externally by a third party rather than internally, it can be addressed faster if a bug bounty program is in place.
A bug bounty program offers financial rewards for reporting vulnerabilities to the organization.
Use a Security-First Approach
In a security-first approach, security is considered a top priority, and the needs of the business are secondary.
It can be done by implementing security measures such as firewalls and intrusion detection systems for the network, continuous monitoring of data and networks, and segregating critical data.
By following these best practices, organizations can improve their DevSecOps process and protect their software from potential attacks.
