DevSecOps is a set of processes that allows operational aspects of organization to be integrated within DevOps. For a long time, development (Dev) business units and operations (Ops) business units aim to build software efficiently and more speed. However, as more cyberattacks and data leaks occur, it has become clear that security (Sec) should be built into the development lifecycle from the start rather than come in at the end as an enhancement. The goal of DevSecOps is to make security an integral and automatic component throughout every phase of the software development lifecycle (SDLC) so that speed does not come at the cost of application security.

The value in DevSecOps is how seamlessly development, security, and operation in to one process. This strategy helps lower risk, improve regulatory adherence, and address security issues at the core of the engineering process instead of at the end where teams tend to separate security from engineering.

What is DevSecOps?
DevSecOps elaborates on the approach of DevOps by incorporating the security requirements in the development life cycle. It brings in security practices and tools in every stage of the software development, which involves reuse of the previously developed code in the CI/CD pipeline.

Core Components of DevSecOps:
What makes DevSecOps different from other methodologies is the fact that security isn’t tacked on at the end of the development pipeline but is considered in each CI/CD stage of the DevSecOps pipeline. This way, security is embedded within the software from the earliest and throughout the software’s lifecycle.

Testing: Embedded in the CI/CD framework are the automated security testing tools so as to be able to identify vulnerabilities during the early stages of development. This encompassed static code, dynamic, and IAST testing.
Scanning: In line with this, develops consists of scanning for security flaws in code, dependencies, or containers with the help of automation scanners. Such scans are typically inserted within the CI/CD pipeline and performed continuously, providing developers with constant feedback.
DevSecOps is not about just throwing in additional security tools into a DevOps process that already exists. It’s a culture of everyone in development, operations, and security taking responsibility for security.

Why Shift from DevOps to DevSecOps?
The move from DevOps to DevSecOps is necessitated by the need to close the loopholes that DevOps practices tend to leave. In order to foster speed as one of its core values, DevOps practice has too much deterioration in the area of security. This means that it is very likely that such issues will be dealt with towards the end of the development cycle or worse, the end-user.

Security Gaps in Traditional DevOps:

Security at the Ending Phase: Traditional DevOps tends to deal with security at the last stage of developing an application. Consequently, it is more reactive than preventive. This kind of practice has an impact on the cost and occurrences of delays when the risk is more uncovered at a late stage.

No Cooperation: DevOps best-attempted chronology consists of obtaining and providing accurate information about the model, where the security teams are rather concerned with maintaining and managing the risk. This division is likely to risk security in software depending upon the contributions from different teams.

Check Security Manually: As a DME approach, any document has to go through a manual style of security which can be difficult and can have delays. Instead of doing security checks manually for example as in traditional DME, DevSecOps approach helps eliminate human errors through automation of the checks.

Transitioning to a DevSecOps paradigm helps organizations progress to integrate security to the application development lifecycle in such a manner that the security risks are attended to in the earliest possible time and that security is not overlooked throughout the entire life cycle. and that security is not overlooked across the entire life cycle.

Benefits of DevSecOps
DevSecOps implements new strategies and processes that accelerate the advancement of organizations. These include:

Increased security: Security controls are embedded into every aspect and phase of SDLC as practiced in DevSecOps, thereby ensuring security issues are dealt with in advance proactively instead of reactively.

Reduced development time: Checking for security controls takes away a lot of manual work hence speeding up the development process. Now people can provide secure code without taking too much time.

More Accessibility: DevSecOps makes it easier for companies to adhere to regulations by enforcing security controls and providing a means of checking compliance.

Effective communication: DevSecOps promotes communication between dev, operations, and security teams, thereby eliminating the attitude that security is the responsibility of the security team only.

Lower Expenses: Fixing security threats in the early stages of system development is less costly than fixing them after the system has been deployed.

How to Transition to DevSecOps
Moving to a DevSecOps model is not only a matter of implementing a new tool, due process has to be applied: new culture, new tools and new procedures. Below shows the way of making this transition:

Culture Shift: Foster a culture in which security is everybody’s business. Foster cross-collaboration and communication between development, operations and security domains.

Automation: Integrate security procedures into the CI/CD process. Make use of static and dynamic application security testing and vulnerability management tools.

Training: Train developers and operation teams in the areas of secure coding, threat modeling, and various security tools available.

Spying: Establish an adaptive intrusion detection system that provides the capability for active response through timely detection of any potential security breaches. Includes the application of performance management, infrastructure management and monitoring of active users.

Gradual Implementation: Ensure that security is part of the process by enhancing the current DevOps practice and later extending it across the software development life cycle.

Transitioning to a DevSecOps posture is not something that can happen overnight; it requires change in terms of mindset as well as tools and workflows.

Tools for DevSecOps
DevSecOps uses several tools to weave security into CI/CD processes. Some of these tools are:

Static Application Security Testing (SAST): Tools such as SonarQube and Checkmarx share a common feature - they examine source code for security vulnerabilities before it is compiled.

Dynamic Application Security Testing: Tools such as OWASP ZAP and Burp Suite are used to verify security in running applications.

Software Composition Analysis (Envelopment Security Testing): Its tools include Snyk and WhiteSource used for searching any known vulnerabilities in open source libraries which are used as dependencies.

Container Security: Tools such as Aqua Security and Twistlock detect and validate invasion of security level of the applications built within containers.

Continuous Integration Tools: CI systems such as Jenkins, GitLab CI/CD and CircleCI may be set up for running security automation tests during the build-deploy pipeline.

These tools assist at every level of the CI/CD pipeline for security purpose making it assess and make risk mitigation at all times.

Challenges and Solutions
With all its benefits, implementing DevSecOps is not without difficulties, though such challenges can be mitigated with some foresight:

Resistance to Change: Teams may resist adopting new processes and tools. Solution: Advocate for the advantages of implementing DevSecOps to the teams and train them on how it enhances security and efficiency in development.

Integration Complexity:: Security tools deployment on a CI/CD pipeline is often a nightmare. Solution: Only include the critical defects that need to be addressed first, and progressively include the rest in a dedicated DevSecOps process.

Skill Gaps: The personnel engaged in the development and operations may not be accustomed to security aspects. Solution: Allocate budgetary resources towards re-training the team to fortify security creativity within the team.

By anticipating these difficulties and dealing with them beforehand, an organization is able to transition to the DevSecOps more smoothly.

Conclusion
DevSecOps extends the capabilities of DevOps by introducing the notion of security during software development cycles. However, with the adoption of the DevSecOps, firms will increase their protection and decrease their expenditure while ensuring efficient cooperation of different organizational units. Moving from DevOps to DevSecOps culture requires as much change in organizational culture, as well as obtaining appropriate tools and ongoing improvements. Given the current increase in the demand for secure, trustworthy and legal applications, organizations must begin the DevSecOps journey now.
