Intrusion Detection System (IDS)

Accelerate Your Threat Detection and Response with a Complete Set of Security Technologies

Get intrusion detection for your network that enables you to inspect traffic between devices, not just at the edge. You can also correlate events from your existing IDS/IPS into a single console for complete network visibility while preserving your investments.

Network Intrusion Detection System (NIDS)

Catch threats targeting your vulnerable systems with signature-based anomaly detection and protocol analysis technologies. Identify the latest attacks, malware infections, system compromise techniques, policy violations, and other exposures.

Host-based Intrusion Detection System (HIDS) and File Integrity Monitoring (FIM)

Analyze system behavior and configuration status to track user access and activity. Detect potential security exposures such as system compromise, modification of critical configuration files (e.g. registry settings, /etc/passwd), common rootkits, and rogue processes.

  • Deploys in Less Than One Hour: Sign up and deploy AlienVault USM quickly. Start seeing actionable alarms in less than one hour.
  • Integrated SIEM Correlation: More than 2,000 correlation directives (and growing) to alert you to the most important threats.
  • Always Vigilant: Automatically receive new IDS signatures and updated correlation directives for the latest threats.
  • Works with Other IDS: Forward IDS and IPS event logs from your existing devices to the USM Sensor for event correlation.

Quickly View Threats in the Dashboard

We utilize the Kill Chain Taxonomy to highlight the most important threats facing your network and the anomalies you should investigate. You can easily see the types of threats directed against your network and when known bad actors have triggered an alarm.

Attack Intent & Strategy

The Kill Chain Taxonomy breaks out threats into five categories, allowing you to understand the intent of the attacks and how they’re interacting with your network and assets:

  • System Compromise – Behavior indicating a compromised system.
  • Exploitation & Installation – Behavior indicating a successful exploit of a vulnerability or backdoor/RAT being installed on a system.
  • Delivery & Attack – Behavior indicating an attempted delivery of an exploit.
  • Reconnaissance & Probing – Behavior indicating an actor attempt to discover information about your network.
  • Environmental Awareness – Behavior indicating policy violations, vulnerable software, or suspicious communications.

Analyze Consolidated Threat Details Faster 

Accelerate your response work by analyzing related threat details in one place.

Event Details: See the directive event, the individual event(s) that triggered the directive event, and the correlation level of the directive rule

You can click on any event to examine details such as:

  • Normalized event
  • SIEM information
  • Reputation of source and destination IP addresses
  • Knowledge base about the event
  • Payload of the packet triggering the event

Powerful Analytics Uncover Threat and Vulnerability Details – All in One Console

Get to the bottom of who and what’s targeting your assets and what systems are vulnerable.

Search SIEM Events

You have the flexibility to conduct your own analysis. For example, you may want to search the SIEM database for events that came from the same host as the offending traffic triggering an alarm.

  • Displays events stored in the database
  • Filters help you find more granular data
  • Sort by event name, IP address, and more

Check Assets and Vulnerabilities

Search the built-in asset inventory for assets involved with an alarm. Integrated vulnerability assessment scans indicate whether an attack is relevant by identifying vulnerable operating systems, applications and services and more – all consolidated into a single view.

  • See all reported alarms and events by asset
  • Modify your mitigation / remediation strategy based on presence of threats targeting vulnerable systems
  • Correlate reported vulnerabilities with malicious traffic

Inspect Packet Captures

Use integrated packet capture functionality to capture interesting traffic for offline analysis. Packets can be viewed in the integrated Tshark tool, or you can download the capture as a PCAP file.

  • Set capture timeout
  • Select number of packets to capture
  • Choose source and destination IP addresses to capture

Examine Raw Logs

Search for any raw logs that are related to activity reported by an alarm. For example, look for logs that are related to the source IP address that was reported in the alarm.

  • Raw logs are digitally signed for evidentiary purposes
  • Filter by time range and search pattern
  • Export raw logs as a text file

Getting Started with AlienVault USM™ for Intrusion Detection

The network intrusion detection system (NIDS) component in AlienVault USM is enabled by default with interfaces and monitored networks configured during the Getting Started Wizard.

Some key benefits of NIDS are:

  • Does not require an agent to be installed on a host, therefore not impacting the performance of any hosted applications
  • Since NIDS detection is essentially transparent, it is highly unlikely that an attacker could interfere with its operation.
  • NIDS sensors are able to collect data from multiple devices, if deployed downstream from them
  • Can work in many different network architectural scenarios and can easily be “moved” to a different location

The host intrusion detection system (HIDS) component in AlienVault USM is simple to set up:

1. Add an agent in the AlienVault USM interface.
2. Deploy the HIDS agent to the target system, either automatically from AlienVault USM, or by manually downloading and installing it.
3. Change the configuration file on the agent to specify the files, folders, and registry keys that you would like monitored.
4. Verify HIDS operations by looking at the HIDS events.

Some key benefits of HIDS are:

  • In terms of deployment, host based IDS sensors tend to be easier since it usually only involves running an installation file.
  • Unlike network based sensors, HIDS does not involve the mirroring of traffic and does not have an impact on the network.
  • Host based intrusion detection is able to log verbose application activity, providing security visibility at the application layer.
  • With HIDS, you are able to run file (and even Windows registry) integrity scans to spot any tampering with sensitive and/or essential files.
  • Only a host based sensor will be able to detect rootkit and other malware installations on your servers and workstations.
