Introduction to Secure Software Development Life Cycle

The software development life cycle has seen many modifications and adjustments since it gained prominence in the 1970s. The developing needs of the end-users combined with the evolving nature of challenges — most notably in terms of security — have led to the formation of different software development approaches and methodologies over time. One of these approaches is the Secure Software Development Life Cycle (SSDLC).

SSDLC came into being as a response to the rising security challenges facing application security. Incidents involving data breaches, privacy violations and other cyberthreats are all too familiar in the present day, and any software development model not designed with security at the forefront will only result in financial and reputational losses for development firms.

There is a need and tangible benefits to having an SSDLC philosophy and application of a security-driven approach through each developmental phase of an SDLC.

But to fully understand and appreciate the importance of SSDLC, let us first look into the classical SDLC approaches.

What is the Software Development Life Cycle?

The Software Development Life Cycle (SDLC) is a systematic yet standardized approach to developing software applications. SDLC borrows elements heavily from general project management life cycle approaches, as
