Secure SDLC practices in Cybersecurity - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does SDLC stand for in software development?

SDLC stands for Software Development Life Cycle. It is a process used to design, develop, and test high-quality software systematically.

Why is security important in the SDLC?

Security in SDLC ensures that software is protected from threats and vulnerabilities from the start, reducing risks and costs of fixing issues later.

Name two key practices in Secure SDLC.

Two key practices are: 1) Conducting threat modeling early to identify risks, and 2) Performing regular security testing throughout development.

What is threat modeling in Secure SDLC?

Threat modeling is a process to identify potential security threats and design ways to prevent or reduce their impact before coding begins.

beginner

How does Secure SDLC help reduce costs?

By finding and fixing security issues early in the development process, Secure SDLC reduces expensive fixes after software release and protects against breaches.

What is the main goal of Secure SDLC?

A To build software with security integrated from the start

B To speed up software delivery ignoring security

C To test software only after release

D To outsource security to third parties

Secure SDLC aims to integrate security into every phase of software development to prevent vulnerabilities early.

Which phase in SDLC is best to perform threat modeling?

A After deployment

B During coding only

C During requirements and design

D After testing

Threat modeling is most effective during requirements and design to identify risks before coding starts.

What type of testing is important in Secure SDLC?

A Security testing

B Only performance testing

C No testing needed

D Usability testing only

Security testing helps find vulnerabilities and verify protections throughout development.

Which practice helps reduce security risks in software development?

A Ignoring security requirements

B Regular code reviews with security focus

C Skipping documentation

D Delaying security fixes until after release

Regular security-focused code reviews help catch issues early and improve software safety.

What is a benefit of integrating security early in SDLC?

A More vulnerabilities in production

B Higher cost to fix issues later

C Longer time to market without benefits

D Reduced risk of security breaches

Early security integration reduces risks and helps prevent breaches in the final product.

Explain the main steps involved in Secure SDLC and why each is important.

Think about how security fits into each phase of software development.

Describe how Secure SDLC helps organizations save money and protect users.

Consider the impact of security issues found late versus early.
