DevOps is the collection of cultural theory, processes, and resources that improve the potential of an enterprise to produce high-speed technologies and services; this helps the organization by accelerated growth and development of goods at faster rates than any organization using typical software development process and infrastructure. This pace allows businesses to provide better quality which helps them to compete effectively in the market.
The combination or hybrid of Security practices and DevOps is referred to as DevSecOps, which mainly emphasizes the particular part of the DevOps for development and delivery channel. The standard notion of DevSecOps emphasizes the development of applications and tries to test the integrity and performance of the system as quickly as possible in the design process.
If we consider the DevSecOps more open, it could be a completely new mindset of practices that spread beyond the particular interpretation of DevSecOps as security automation. The DevSecOps could be a culture of techniques that enhance the development process and its Security and the overall business results of an organization.
The main question that now arises here is how we can measure the Security and how can CISO/Leadership use DevSecOps to enhance it. Security metrics can be used to determine how the cybersecurity program of a company meets targets and guarantees compliance. These benchmarks provide insights into what works in the cybersecurity environment to strengthen the procedures and fill any loopholes.
01
There are four principles from which we can measure security
The first one is to consider the security metrics at the organizational level rather than the team level. The main objective of DevSecOps is to help the organization achieve its goals rather than just a team.
The second one is to consider measuring the outcomes rather than the output of a process. For example, if a team is running tests to reduce cyber attacks in an organization, then rather than counting the number of tests performed or the number of hours spent to run these tests, consider how much it has helped reduce the chance of getting attacked
The third one is to increase the potential of the entire organization to detect and respond to any malicious activity rather than relying on some static figures indicating maturity in some specific area of protection
The fourth is always to consider the bigger picture, meaning that you don't need to analyze each component's Security. But look at it as a part of a bigger picture and enhance the Security overall.

Some of the security metrics that a CISO should consider include :
Deployment Metrics which indicates production and deployment stability of the system
Lead Time metrics suggest the ability of an organization to accept the change and behave accordingly
Mean Time Repair Metrics which demonstrates the ability of a system to get back on its feet after an attack
03
Some vital security metrics needs consideration from the board, which are :
Time to Detection is the time the system takes to detect the first incident; for example, during a system update, a threat appears in the system, but the actual time to discover that threat so that company takes mitigating actions, is called the Time to Detection. It is one of the most crucial security metrics for every organization.
Time to Remediation is the second most significant metric after Time to Detection. It is the time taken by the team or security engineers to eliminate the threat of any kind or problem from the system. From Detection to eradication will be considered time to Remediation.
Visibility is also one of the crucial metrics considered by the board. It means how much access to the logs of the environments currently in use by the organization you have and how well you analyze them. For example, if you have live environments in your system, how much visibility of the logs and data you have in your hand, is it any less than the other environments currently in use, and the tradeoffs. If you don't have sufficient access to the data logs, it may affect the system's threat detection and response capabilities.
It is increasingly becoming important for the regulators and boards to demonstrate measurable compliance to the prominent industry standards such as NIST and accumulated security view of all cloud usage.
