Question 1 of 30
A financial institution is implementing a new intrusion prevention system (IPS) that utilizes Cisco\'s Sourcefire technology. The security team is tasked with ensuring that the IPS is updated with the latest signatures to protect against emerging threats. They decide to schedule signature updates every 24 hours. However, they also want to implement a strategy to manage the updates effectively, considering the potential impact on network performance and the need for immediate protection against critical vulnerabilities. What is the most effective approach for managing signature updates in this scenario?
Schedule daily automatic updates and configure the IPS to apply critical updates immediately while allowing non-critical updates to be applied during off-peak hours.
Only apply updates on a weekly basis to minimize disruption to network performance.
Disable automatic updates and manually apply all updates once a month to ensure thorough testing.
Implement updates only when a significant threat is detected, regardless of the scheduled update cycle.
