What is meant by the 'attack surface'? [ Ans: ] All points where
Guru01 - Stuvia
an attacker can interact with the system.
Why is software security relevant today? [ Ans: ] Software
controls critical infrastructure and is often a primary attack vector.
What increases the cost of fixing software flaws? [ Ans: ]
Delaying fixes until post-release increases costs up to 200x.
How do quality and secure code differ? [ Ans: ] Quality code is
usable and maintainable; secure code resists exploitation.
How does SDL reduce risk? [ Ans: ] By embedding security
throughout the development lifecycle.
What does it mean to 'build security in'? [ Ans: ] Designing and
implementing security from the earliest development stages.
Why is human expertise important in SDL? [ Ans: ] Tools can't
replace a security architect's insight and adversarial thinking.
What does SDL stand for? [ Ans: ] Security Development
Lifecycle.
What is the purpose of SDL? [ Ans: ] To integrate security best
practices into software development.

milestones, activities, and roles.
What are A1 deliverables? [ Ans: ] Discovery summary, SDL plan,
and PIA plan.
What is the value of early threat identification? [ Ans: ] Reduces
cost and improves design.
