Intrusion Detection System (IDS)
With powerful intrusion detection system capabilities and integrated threat intelligence, AlienVault Unified Security Management (USM) accelerates threat detection in the cloud and on-premises – all in a single easy-to-use platform that deploys in minutes.
Accelerate Threat Detection with
Intrusion Detection Systems
AlienVault® Unified Security Management™ (USM™) delivers built-in intrusion detection systems for your critical IT infrastructure, enabling you to detect threats as they emerge in the cloud and on premises. With AlienVault USM, you can also collect and correlate events from your existing IDS/IPS into a single console for complete security visibility while protecting your investments.
USM provides comprehensive intrusion detection as part of an all-in-one unified security management console. It includes built-in host intrusion detection (HIDS), network intrusion detection (NIDS), as well as AWS IDS and Azure IDS for your public cloud environments.
To ensure that you are always equipped to detect the latest emerging threats, AlienVault Labs Security Research Team delivers continuous threat intelligence updates directly to USM. This threat data is backed by the AlienVault Open Threat Exchange™ (OTX™)—the world’s first open threat intelligence community.

Intrusion Detection Systems for Any Environment
Intrusion Detection in the Cloud
While traditional IDS software is not optimized for public cloud environments, intrusion detection remains an essential part of your cloud security monitoring. That’s why USM Anywhere™ provides native intrusion detection system (IDS) capabilities in AWS and Azure cloud environments. Purpose-built cloud sensors in USM Anywhere leverage the control plane management tools in AWS and Azure, giving you full visibility into every operation that happens in your cloud “data center.”
Network Intrusion Detection System (NIDS)
On premises, use the built-in network intrusion detection system (NIDS) to catch threats targeting your vulnerable systems with signature-based anomaly detection and protocol analysis technologies. NIDS sensors collect data from multiple on-premises applications, systems, and devices to 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)
Host Intrusion Detection Systems (HIDS) enable you to analyze system behavior and configuration status to track user access and activity. With built-in HIDS in USM, you can detect potential security exposures such as system compromise and changes to critical configuration files (e.g. registry settings, /etc/passwd), common rootkits, and rogue processes.
Benefits of Host Intrusion Detection include:
- Simple installation of HIDS sensors
- The ability to log verbose application activity, providing security visibility at the application layer
- The ability to run file and Windows registry integrity scans to spot any tampering with sensitive and essential files
- Rootkit detection and other malware installation detection on your servers and workstations
Quickly View Threats in the Dashboard
USM uses the Kill Chain Taxonomy to highlight the most important threats facing your environment and the anomalies you should investigate. You can easily see the types of threats directed against your critical infrastructure 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 cloud environment, on-premises 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.
Complete Threat Evidence
See attack methods, related events, source and destination IP addresses, as well as remediation recommendations in a unified view, so you can investigate and respond to threats faster.
Reduced Noise
Correlating IDS/IPS data with multiple built-in security tools reduces false positives and increases accuracy of alarms.
Automatic Notifications
Set up email notifications to proactively inform you of critical alarms that may indicate a system compromise or attack.
Workflow Management
With USM Appliance™, you can easily create tickets from any alarm, delegate to users, or integrate with an external ticketing system to manage your response and remediation activities.
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 and Analyze Events
You have the flexibility to conduct your own analysis. For example, you may want to search for events that came from the same host as the offending traffic triggering an alarm.
- Search events to identify activity and trends
- Filters help you find more granular data
- Sort by event name, IP address, and more
- Examine raw log data related to alarm activity
- Raw logs are digitally signed for evidentiary purposes
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
Examine Event Details
See the alarm, the individual event(s) that triggered the alarm, and the priority of the alarm.
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
- Forensics data about what triggered the event
Inspect Packet Captures
Use integrated packet capture functionality to capture interesting on-premises traffic for offline analysis. In USM Appliance, packets can be viewed in the web user interface, 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
Integrated Threat Intelligence from AlienVault Labs Security Research Team
The AlienVault Labs Security Research Team constantly scours the global threat landscape to identify the latest attack methods, bad actors, and vulnerabilities that could impact your security. The team curates this data and delivers continuous threat intelligence updates directly to your USM environment, so you always have the most up-to-date threat intelligence as you monitor your environment for emerging threats.
Every day, AlienVault Labs collects millions of threat indicators, including data from the Open Threat Exchange (OTX), the world’s first truly open threat intelligence community. This community of security researchers and IT professionals share threat data as it emerges “in the wild,” so you get global insight into attack trends and bad actors that could impact your operations.
