Introduction: Fundamentals of Security Process with DevOps

Security in DevOps, has become an integral part of modern software development processes. Traditional security approaches were integrated at the end of the development cycle, so identifying and fixing potential security vulnerabilities could be time-consuming and costly. DevOps aims to solve this problem by integrating security processes into development and operations processes. Thanks to this integration, vulnerabilities can be detected and fixed early, thus increasing the overall security of the software.

The DevOps philosophy is based on agility, collaboration, and automation. Integrating security into this philosophy is not only a necessity, but also a competitive advantage. A secure DevOps environment supports continuous integration (CI) and continuous deployment (CD) processes, allowing software to be released faster and more securely. Automating security testing in these processes minimizes human errors and ensures that security standards are continuously applied.

• Early detection of security vulnerabilities
• Faster and safer software distribution
• Reduced risk and cost
• Improved compatibility
• Increased collaboration and transparency

A secure DevOps approach requires development, operations, and security teams to work collaboratively. This collaboration ensures that security requirements are considered from the beginning of the software development process. By automating security testing and analysis, teams can continuously assess the security of code. Additionally, security training and awareness programs increase security awareness among all team members and help them be more prepared for potential threats.

Security in DevOps, is not just a set of tools and techniques. It is also a culture and an approach. Placing security at the heart of the development process ensures that software is safer, more reliable, and released faster. This increases the competitiveness of businesses and allows them to better serve their customers.
