ISC2 CISSP Practice Question

The correct answer is Managing hardware-based security features and physical attack vectors. Embedded systems security uniquely requires consideration of hardware-based security features and physical attack vectors. Unlike web applications, embedded systems often have direct physical accessibility, specialized hardware security modules, physical tamper protection requirements, and limited computational resources that create unique security challenges. Managing these hardware-specific security considerations has no direct equivalent in web application security.

Protection against buffer overflow attacks is incorrect because buffer overflow protection is important in both embedded systems and web applications, particularly those written in languages like C or C++. This is not unique to embedded systems.

Input validation for user data is incorrect because input validation is a fundamental security practice in all types of applications, including both embedded systems and web applications. The specific validation techniques might differ, but the principle remains the same.

Authentication of users is incorrect because authentication is a common security requirement across all types of systems. While implementation details may vary, the basic concept of authenticating users applies equally to embedded systems and web applications.
