Intrusion Detection

Topics Discussed

Product Overview

The Host-based Intrusion Detection/Intrusion Prevention Service (IDS/IPS) provides an agent-based system that is installed on a Host for network traffic analysis and reporting based on policies defined by Armor. Armor utilizes an enterprise-class IDS/IPS application and deploys the application agent with the Armor Agent. The IDS/IPS agent registers with an Armor management console, which receives IDS/IPS events in real-time. IDS/IPS event details are available in the Armor Management Portal (AMP). Armor's IDS/IPS policies are designed to detect network based events.

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.

To fully use this screen, you must add the following permission to your account:

Read IDS

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.

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.

For cloned assets with the Trend sub-agent installed, users will still need to enable the modules and run recommendation scans as needed.

You can also manage the Trend sub-agent in the Armor Toolbox.

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.

Recommendation Scans work in tandem with the Auto-Apply configuration for IPS. The results of the Recommendation Scan can only be applied when Auto-Apply for the IPS service is turned on.

Install Trend Sub-Agent:

CODE

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

Uninstall Trend Sub-Agent:

CODE

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

Trend Sub-Agent Status:

CODE

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

Turn On Recommended Scans:

CODE

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

Turn Off Recommended Scans:

CODE

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):

CODE

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

Set Recommendation Scan Interval:

CODE

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

CODE

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

Trend Sub-Agent Help

CODE

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

Restart Trend:

CODE

Windows: C:\.armor\opt\armor.exe trend service-restart
Linux: /opt/armor/armor trend service-restart

Enable Intrusion Prevention Service

Use the following commands to manage the Intrusion Detection service.

Turn On Detect Mode:

CODE

Windows: C:\.armor\opt\armor.exe ips detect 
Linux: /opt/armor/armor ips detect

Optional Parameters
Windows: C:\.armor\opt\armor.exe ips detect auto-apply-recommendations=on
Linux: /opt/armor/armor ips detect auto-apply-recommendations=on

Windows: C:\.armor\opt\armor.exe ips detect auto-apply-recommendations=off
Linux: /opt/armor/armor ips detect auto-apply-recommendations=off

The Auto-Apply configuration for IPS works in tandem with Recommendation Scans. Only after a Recommendation Scan is run will there be policies to Auto-Apply.
