CompTIA CySA+ Practice Test

Which practice is best for keeping a newly installed security appliance functional and secure?

1. Monitoring staff activities

2. Regularly updating and patching the appliance

3. Limiting access to the appliance

4. Using the appliance without maintenance

The correct answer is: Regularly updating and patching the appliance

Regularly updating and patching the appliance is essential for maintaining its functionality and security. Security appliances, like any software or hardware, can be vulnerable to exploitations and attacks if not properly maintained. When new vulnerabilities are discovered, vendors typically release patches and updates to address these weaknesses. By ensuring that the appliance is regularly updated with the latest security patches, you effectively reduce the risk of successful attacks that could compromise the system. Moreover, these updates can include improvements in performance, features, and functionality that help keep the appliance operating efficiently. While other practices such as monitoring staff activities, limiting access, and performing maintenance are important aspects of a comprehensive security strategy, they do not directly address the vulnerabilities that can arise from outdated software or firmware, which are critical to keeping the appliance secure over time. Therefore, regular updates and patching are fundamental to the ongoing protection and optimal functioning of a newly installed security appliance.
