Historically, security was an add-on that is integrated at the last stage of development in most software applications in today’s world. Nevertheless, due to the increasing wave of DevSecOps, this paradigm will shift significantly. In this article, we compare implementing DevSecOps with traditional security measures to know more about the functionality of DevSecOps points of interest, and the burdens of this new methodology. 

We'll also explore the benefits and challenges of implementing DevSecOps in modern software development environments.

What we are observing today in the software industry is a transition in how security is being incorporated into the software development life cycle. 

DevSecOps basically stands for Development, Security, and Operations and implies a cultural and technological approach that is targeted at integrating security at all stages of SDLC. 

This approach also differs radically from the approach of other security measures, which are often implemented independently of development teams. 

Implementing DevSecOps: Current State

Adoption and Market Penetration

The aspects covering the DevSecOps practice have been on the rise over the past few years. It was established in a 2022 Gartner survey that a third of organizations had incorporated DevSecOps into their practices, compared to a quarter in 2020. 

This growth is highlighting awareness of security integration in the context of SDLC practices. 

Also, currently, DevSecOps has about 20-50% market coverage, which only grows, meaning it has become more accepted as a standard for developing software. 

Implementing DevSecOps is becoming increasingly crucial for organizations looking to stay competitive and secure in the rapidly evolving software development landscape.

The need to adapt more contemporary ways of security cannot be overemphasized since Gartner predicts that 80% of the firms that fail to incorporate such strategies will suffer a decline in operational efficiency and coping capacity in the area of cyber threats by the end of 2023. 

This statistic wakes up organizations that are still stuck with traditional security models. 

Key Differences and Benefits

Typically, one of the critical distinctions that can be observed in the case of DevSecOps compared to traditional security solutions can be identified in the presence of security built into the development process from start to finish. 

DevSecOps practices the act of incorporating security into the development process, more specifically, shifting these considerations to the beginning of the SDLC, better known as, shifting left. 

With this approach, security risks are mitigated at an earlier stage hence making a huge difference from the usual process where most securities are checked at the phase of the SDLC known as testing. 

Implementing DevSecOps offers numerous advantages over traditional security approaches, including improved collaboration, faster vulnerability detection, and enhanced overall security posture.

DevSecOps is characterized by the methods used, particularly the automation and efficiency of the processes in place. 

DevSecOps means reaching the intended results in terms of security checks through the enhanced focus on automation, which enables continuous checks and, therefore, the possibility to detect vulnerabilities faster. 

This in turn translates to increased revamped cycles for great timetables to market as opposed to traditional security strategies that involve manual checkups that are normally slow and involve human error. 

A major advantage of DevSecOps also concerns the precision of the security testing. 

According to Cisco, it was established that the majority of the security notifications received were fake alarms, 77% of them to be precise, this just goes to show that there needed to be more accurate testing approaches. 

False positives are avoided by integrating an effective testing methodology in DevSecOps, while on the other hand, false negatives are also prevented while going for a broad automated testing process. 

This increase in accuracy not only reduces the time spent on performing such assessments but also enables the security teams to concentrate directly on valid risks and not pray on nonexistent threats. 

Cultural Shift and Collaboration

Undoubtedly, one of the key advantages of implementing DevSecOps is the change in organizational culture compared to traditional security methods. 

DevSecOps is a practice where all the stakeholders, especially the development, operation, and security departments, embrace security as a common practice. 

This approach shares contrast to norms practiced as security becomes a process that is usually separated from the rest of the organization, reducing communication and enhancing the vulnerability time it takes to address them. 

When security principles are adopted into the development process, then the end products that are developed are quality products and are reliable. It helps to create fewer conflicts during code review, improving the general user experience and helping to achieve the same goal. 

When security is everyone's concern, then organizations will help in developing a more secure software environment. 

Challenges and Considerations

The ways that DevSecOps is beneficial are numerous, however, it is indispensable to state that DevSecOps is not a full replacement for classical security approaches. 

It is also common for organizations to integrate DevSecOps with conventional SOC as a blended strategy in order to deliver the above outcomes. Indeed, the usage of both approaches offers a broad security profile by taking all the advantages of the two methodologies. 

The first of these essential shifts is the issue of skillset, which remains one of the major issues as organizations transform to DevSecOps. 

An organization’s teams must acquire new knowledge and skill sets regarding cybersecurity, which can be challenging for some teams. 

This challenge hits the importance of training and continuing education that will make a way for all members in the team to be in a position to contribute or support the security of the developed software. 

The Future of Software Security

When turning to the future, one can conclude that DevSecOps is a major step forward in the process of integration of security measures within the SDLC application of security activities during system development and the development of trust among business teams makes it possible for firms to operate effectively with strong security systems. 

The statistics speak for themselves: DevSecOps is already found in the market with a market coverage level of 20-50% and while the adoption has risen by 9% within just two years, DevSecOps can be said to be faster turning into the rule than the exception. 

Any organization that is slow to adapt is one step behind competitively as well as insecure, and in today’s fast-moving market that is a serious problem. 

But shifting to DevSecOps isn’t so smooth. It implies a reorientation of thinking, working activity, and competencies. This implies that organizations have to make sure they are willing to invest time and pay for training, tools, and change management to make full use of such an approach. 

Lastly, it is important to note that though conventional security strategies have been effective for a long time, the evolving threats’ levels and frequency require a more holistic and preventive strategy. 

DevSecOps is presented as a fruitful approach that integrates security into the rapid tempo of software delivery. 

For many organizations in the future, the pertinent issue will not be about when or if to embark on DevSecOps, but how soon or how fast they can adopt this revolutionary approach for the viability and security of their software in a highly technological world.
