Which of the following is not an issue with patching?
a. Few patches exist for application software
b. Patches address zero-day vulnerabilities
c. Delays in patching OSs
d. Difficulty patching firmware
The correct answer and explanation is:
Correct Answer: b. Patches address zero-day vulnerabilities
Explanation:
Patching is an essential process in cybersecurity, ensuring that vulnerabilities in software, operating systems, and firmware are addressed to prevent exploitation by attackers. However, some challenges accompany patching, and option b does not represent an issue with patching. Here’s why:
Why “Patches address zero-day vulnerabilities” is incorrect:
Zero-day vulnerabilities are security flaws that are unknown to software vendors or the public and are exploited by attackers before a patch or fix is available. While patches can eventually address zero-day vulnerabilities, they are created and released after the vulnerability is discovered and analyzed. This means there is an inherent time delay between discovery and patching. The fact that patches can address zero-day vulnerabilities is a strength, not a challenge, of patching.
Common Issues with Patching:
- Few patches exist for application software (Option a): Many application software programs, especially older or niche ones, may lack regular updates or patches. This leaves systems reliant on such software vulnerable.
- Delays in patching OSs (Option c): Operating system patches may not be applied immediately due to testing requirements, compatibility concerns, or administrative delays. These delays can leave systems exposed.
- Difficulty patching firmware (Option d): Firmware resides on hardware devices and often requires specialized tools or manual processes to update. The process is more complex than software updates, leading to potential vulnerabilities if not patched promptly.
Conclusion:
While patching addresses vulnerabilities, its challenges include delays in application, limited availability of patches, and technical difficulties with firmware updates. However, the ability to address zero-day vulnerabilities through patching is not a problem—it is a key benefit of the patching process.
