Cisco Cyber Security Practice Exam

What is the recommended countermeasure for keeping software updated?

1. Improve user training

2. Update and patch all operating systems and software applications

3. Implement multi-factor authentication

4. Establish strict download policies

The correct answer is: Update and patch all operating systems and software applications

Keeping software updated is crucial for maintaining security, as updates often include patches for vulnerabilities that could be exploited by attackers. The recommended countermeasure of updating and patching all operating systems and software applications directly addresses this need. By regularly applying updates, organizations can mitigate risks posed by known vulnerabilities, ensuring that security weaknesses are resolved and reducing the attack surface for potential threats. Updates can also include performance improvements and new features, contributing to the overall efficiency of the software. Therefore, establishing a routine for timely updates and patching not only enhances security but also helps maintain the reliability and functionality of applications and operating systems. The other options, while beneficial in their respective contexts, do not specifically address the necessity of keeping software and systems up to date. Improved user training may raise awareness but does not substitute for the actual application of updates. Multi-factor authentication enhances access security but does not protect against vulnerabilities in software. Similarly, strict download policies can help control malicious software installations, but they do not ensure that existing software remains updated to safeguard against known threats.
