Input

validation alone is sufficient to prevent all types of web security attacks.

A

system can be considered useful if it has high usability even when it lacks

necessary functionality.

Authentication

ensures that users can only access resources they are permitted to use.

Memorability

refers to how easily users can reestablish proficiency after a period of

non-use.

Trusting

user input without validation can lead to serious security vulnerabilities.

Enterprise

architecture frameworks define the architecture itself rather than providing a

structure for organizing it.

Security

vulnerabilities often arise from implicit trust between system components.

Escaping

output is one of the primary defenses against cross-site scripting (XSS).

Defense-in-depth

means relying on a single strong security control to protect a system.

Enterprise

architecture supports decision-making by providing structured insights into

dependencies and impacts.
