Complete SSDLC Guide: Best Practices for SDLC Security and Vulnerability Management

A health tech startup recently launched a new web application and scheduled a penetration test with Mand Consulting Group. The test reveals several vulnerabilities, including an SQL injection flaw and weak access controls. All the findings were uploaded to their WatchDog Security dashboard, allowing centralization. By addressing these issues immediately, the startup enhances its security and strengthens its compliance with industry regulations.

1. What are the 5 phases of the security life cycle?

The SSDLC comprises five key phases: Planning, Design, Implementation, Testing, and Maintenance. Each phase incorporates security practices to identify and mitigate vulnerabilities throughout the development process.

2. What is the difference between SDLC and Agile security?

In Agile, security is integrated continuously, with frequent updates and iterative reviews, whereas traditional SDLC often addresses security at specific stages. Agile’s flexibility allows for ongoing security assessments, making it more adaptable to emerging threats.

3. What are the 5 D’s of SDLC?

The 5 D’s typically refer to Define, Design, Develop, Deploy, and Defend. These steps emphasize the need for security considerations from the initial concept through to deployment and ongoing protection. While they do a great job of providing a generalized concept, OWASP’s SwSec 5D Framework is significantly better as it is tied to OWASP’s broader security principles and best practices, offering more industry-recognized guidance.

4. Why do we need secure SDLC?

Integrating security into the SDLC helps prevent vulnerabilities from being introduced during development, reducing the risk of breaches, protecting data, and ensuring compliance with regulations such as SOC 2,ISO 27001, CyberSecure Canada, HIPPAand more.

5. How can you include threat modelling within your SSDLC?

Threat modelling can be integrated during the design phase to identify potential threats and vulnerabilities early on. This proactive approach allows for tailored security controls to be implemented throughout the development process.

Failing to implement security in SDLC phases can lead to undetected vulnerabilities, which increase the likelihood of successful attacks, data breaches, and significant financial and reputational damage.
