DevSecOps is the answer to integrating these various challenges into a coherent and effective approach to software delivery. It is a new method that helps identify security issues early in the development process rather than after a product is released.
DevSecOps can reduce the costs associated with fixing security flaws, by building security into every stage of the development process, from the requirement stage onwards.
Privacy and security principles should be integral to any company’s culture via DevSecOps best practices, and they should be endorsed at board level. Security must be part of the application development process. DevSecOps makes everyone responsible for security.
-
Cost reduction
achieved by detecting and fixing security issues during the development phases which also increases the speed of delivery
-
Immutable infrastructure
which allows companies to tear down infrastructure while managing an attack vector identified by scanning. If a node is compromised, it won’t remain compromised for long, as it will be torn down and rebuilt with new credentials. Zero defects in the code is the ideal to aim for, although zero variations are the minimum requirement.
-
Threat hunting
which can avoid bad publicity, and therefore can potentially increase brand value. It is obviously easier to sell a secure product.
-
Speed of recovery
which is enhanced in the case of a security incident by utilizing templates and pet/cattle methodology.

Lastly...
Immutable infrastructure improves overall security by reducing vulnerabilities, reduces insecure defaults, and increasing code coverage and automation. It also encourages companies to move to the cloud instead of using depreciating and increasingly vulnerable hardware.
