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 refers to the process of updating software, operating systems, and firmware to fix bugs, address vulnerabilities, and improve functionality. While patches are crucial for maintaining security and performance, there are various challenges associated with implementing them effectively.
The correct answer, “Patches address zero-day vulnerabilities,” is not an issue with patching but rather one of its primary purposes. A zero-day vulnerability is a software flaw that is unknown to the vendor and has no patch available at the time of its discovery. Once identified, vendors release patches to address these vulnerabilities. However, the effectiveness of a patch depends on timely deployment by users, which is a separate challenge.
Issues with Patching:
- Few patches exist for application software: Some software developers may not provide regular updates or patches, particularly for outdated or niche applications. This leaves such software vulnerable to exploitation.
- Delays in patching operating systems (OSs): Many organizations delay patch deployment due to compatibility concerns, lack of resources, or fear of disruptions. These delays create windows of opportunity for attackers to exploit known vulnerabilities.
- Difficulty patching firmware: Firmware updates are often more challenging than software updates. They may require device downtime, special tools, or expertise, leading to delays in deployment. Additionally, older hardware may no longer receive firmware updates.
In contrast, addressing zero-day vulnerabilities is a proactive aspect of patching. Vendors prioritize releasing patches for such vulnerabilities because they pose an immediate risk. The true issue lies not in the patches themselves but in the time taken to create, distribute, and deploy them. Organizations must balance the need for security with operational continuity, highlighting the importance of a robust patch management strategy.
