Intrusion Detection

Armor's IDS/IPS, powered by the Armor's threat prevention and response platform, monitors your environment, and alerts you and our elite Armor Security Operations Center (SOC) experts to potential threats, allowing for a quick and accurate response. All event data collected by the Armor IDS/IPS is integrated with data collected by other security appliances under monitoring by Armor, and correlated to identify suspicious patterns and behavior. Unlike traditional service providers, our security experts in the SOC go beyond alerting to help your security team quickly respond to the threat and minimize risk it may pose.

You can use the Intrusion Detection System screen to view data from the host-based intrusion detection system (HIDS).

Intrusion Detection Systems (IDS) analyze network or host traffic and alert if that traffic matches signatures of known attacks. These events are correlated in our Security Information Event Management (SIEM) system, in combination with other security data, to alert on security threats.

This system provides an agent-based, intrusion detection service for network traffic analysis and reporting. Specifically, HIDS monitors for attack attempts.

Any observed attempts are delivered to Armor's advanced correlation engine for inspection and correlation with other collected logs.

Understand Intrusion Detection System (IDS)

This section displays details for all IDS events detected over the past 7 days.

Enable Trend Sub-Agent

As a prerequisite to installing Intrusion Prevention Services, you must install the Trend sub-agent. Use the following commands to manage the Trend sub-agent.

Recommendation Scans

One of the features available in Agent 3.0 is Recommendation scans. Recommendation scans provide a good starting point for establishing a list of rules that you should implement. During a recommendation scan, the Armor Agent scans the operating system for installed applications, the Windows registry, open ports, and more. To take advantage of Recommendation scans, turn on Ongoing Recommendation scans in the Toolbox.

Install Trend Sub-Agent:

Windows: C:\.armor\opt\armor.exe trend install
Linux: /opt/armor/armor trend install

Uninstall Trend Sub-Agent:

Windows: C:\.armor\opt\armor.exe trend uninstall
Linux: /opt/armor/armor trend uninstall 

Trend Sub-Agent Status:

Windows: C:\.armor\opt\armor.exe trend status
Linux: /opt/armor/armor trend status

Turn On Recommended Scans:

Windows: C:\.armor\opt\armor.exe trend ongoing-recommendation-scan on
Linux: /opt/armor/armor trend ongoing-recommendation-scan on

Turn Off Recommended Scans:

Windows: C:\.armor\opt\armor.exe trend ongoing-recommendation-scan off
Linux: /opt/armor/armor trend ongoing-recommendation-scan off

Schedule a Recommended Scan (Runs on Next Trend Sub-Agent Heartbeat):

Windows: C:\.armor\opt\armor.exe trend recommendation-scan
Linux: /opt/armor/armor trend recommendation-scan

Set Recommendation Scan Interval:

Windows: C:\.armor\opt\armor.exe trend set-recommendation-scan-interval <interval>
Linux: /opt/armor/armor set-recommendation-scan-interval <interval>

 Options are  "24 Hours" "2 Days" "3 Days" "7 Days" "2 Weeks" "3 Weeks" "4 Weeks"

Get Recommendation Scan Interval:

Windows: C:\.armor\opt\armor.exe trend get-recommendation-scan-interval
Linux: /opt/armor/armor trend get-recommendation-scan-interval
