An effective DevSecOps strategy involves three key components: Secure-by-design, defence-in-depth, and shift-left security.
Secure-by-design is a cybersecurity approach that allows businesses to automate data security controls and build security into IT processes from the outset.
It focuses on stopping a breach rather than one happening, then fixing it. Secure-by-design looks to continually manage, monitor, and maintain security risks.
The cloud makes it easier for developers to accomplish security-by-design. Originating from a military strategy, defence-in-depth is a layered security architecture that provides defence measures, in case a vulnerability is exploited or a control fails.
The idea is to delay a cyber attack rather than defeat it. Defence-in-depth utilizes physical, technical, and administrative security controls.
The secure-by-design concept forces shift-left security, meaning IT security is implemented at the earliest design stages, reducing the costs associated with exposing potential security issues further down the line.
The sooner a threat is diagnosed, the cheaper it is to remove and secure it.
