What is the BEST immediate action if suspicious activity is discovered in your network?

1. Contact your ISP to request they block the traffic.

2. Wait until traffic has been identified before making changes.

3. Create a new policy rule to block the traffic.

4. Create a Suspicious Activity Monitoring (SAM) rule to block that traffic.

The correct answer is: Create a new policy rule to block the traffic.

When suspicious activity is detected on your network, creating a new policy rule to block that traffic is the most effective immediate response. This action allows you to swiftly mitigate potential threats and prevent further malicious activity or data breaches. Policy rules are fundamental components of network security that define permissible and impermissible traffic, and adjusting these rules in response to suspicious behavior is a crucial step in securing the network environment. Blocking the suspicious traffic immediately helps safeguard the integrity of the network and can prevent data leaks or intrusion attempts from escalating. It also demonstrates a proactive security posture, where the focus is on containing threats as soon as they are identified. While other options might seem valuable, they lack the immediacy and effectiveness of creating a policy rule. Contacting your ISP could lead to a delay in action and might not address the immediate security concern. Not acting until the traffic is identified or waiting could expose the network to further risks. Although creating a Suspicious Activity Monitoring (SAM) rule could help with ongoing monitoring of such activities, it may not provide the immediate blocking of malicious traffic that is usually necessitated in these situations.
