With the expansion of the DevOps and DevSecOps models, the concept of "shifting left" in the software development life cycle (SDLC) has become popular. Shifting key operational and security actions earlier in the cycle allows detecting vulnerabilities as early as possible. This has significant value, as the later a vulnerability is discovered, the harder and more costly it is to remediate.
To embrace this, organizations need to integrate security checks and vulnerability detection into every step of the SDLC, rather than thinking of them as gates. Shifting left is about making security more developer-centric and providing security feedback while they are coding.
Why Move Security to Development? Shift-left security is key to delivering quality software at speed. Instead of running security audits at the end of the SDLC, shift-left makes security an integral part of everyone's job: developers, operations, and application security or threat response teams.
Security tasks should be automated and integrated within the development and deployment pipeline. Automated scans must happen at each incremental change at the exact moment they are written so that:
Vulnerabilities are not discovered late in the development cycle.
Developers and operations are quickly notified whenever potential vulnerabilities are committed, enabling them to quickly detect and correct security issues within their daily work.
Developers can rapidly learn from their errors and apply best practices concerning code hygiene.
By better integrating application security objectives into daily work, teams can achieve higher levels of software delivery performance and build more secure applications. This helps build accountability among non-security team members.
Developers may be concerned that security scans will add extra work and slow ..
