Question

Review of the recent finding in the cybersecurity area that relates to Operating System vulnerabilities being exposed. The OS can iOS, Android, Windows, Linux, OS X, etc. You choose.

The write up must include:

• An explanation of the vulnerability that was exposed/attacked
• What the impact of the exposure/attack was
• What the fix for the vulnerability was (if publicly available)
• Lastly - and most importanly - what practices you've learned in this course (book, lecture slides, readings, videos, etc) that either could have been put in place to prevent it, or will be needed to remediate it.

Answer 1

Buffer Overflow Problem:

This happens when there is more data in buffer that can handle and data is overflown to the adjacent memory.

This vulnerability will lead to system crash or the attacker can gain entry for a cyber attack.

Coding errors and common mistakes in app development especially by using c/c++ languages result in the attack.

Inorder to prevent this,

Developers should avoid using standard library function which are not bound-checked.

Security practices such as regular testing to detect and avoid buffer overflow.

Enabling automatic protection at the language level.

Bounds-checking enabled at runtime.
