Threat Behavior Analysis with Omnis: Uncovering Hidden Attacks

In today’s cyber landscape, where attackers are becoming increasingly sophisticated, traditional signature-based defenses are often ineffective. Behavioral Threat Analysis (UEBA) is becoming an essential tool for detecting complex, low-level attacks that slip past other systems. Omnis, a solution from NWU, provides powerful capabilities in this area, enabling security professionals to identify and neutralize threats before they cause serious damage.

The Evolution of Cyber Threats and the Need for Behavioral Threat Analysis

Cyber threats are constantly evolving, and attackers are developing increasingly sophisticated techniques to penetrate networks and cause damage. APT (Advanced Persistent Threat) attacks, aimed at gaining long-term unauthorized access, are particularly difficult to detect. They often involve gradual infiltration, lateral movement within the network, and masquerading as legitimate activity.

Traditional security systems, such as firewalls and antivirus software, rely on signatures of known threats. However, they are unable to detect new, previously unknown attacks, as well as those that masquerade as normal behavior of users and devices. This is where behavioral threat analysis comes to the rescue.

Omnis: Behavioral Threat Analysis in Action

Omnis is a platform for Threat Detection and Response (XDR) that uses behavioral threat analysis to identify anomalies in the behavior of users, devices, and network traffic. It constantly monitors and analyzes data from various sources, including security logs, network traffic, and endpoint data, to create profiles of normal behavior. Omnis then uses these profiles to detect deviations that may indicate malicious activity.

How Omnis Detects Network Anomalies

Omnis uses several methods to detect network anomalies:

• Traffic Analysis: Omnis analyzes network traffic to identify unusual communication patterns, such as communication with suspicious IP addresses or domains, non-standard use of protocols, or strange volumes of data transmitted.
• User Behavior Analysis: Omnis monitors user activity, such as login times, applications used, and data accessed, to identify deviations from their normal behavior. For example, if a user suddenly starts downloading large volumes of data or accessing confidential files, this may be a sign of a compromised account.
• Device Behavior Analysis: Omnis monitors the behavior of devices connected to the network to identify anomalies, such as the installation of unauthorized software, unusual resource usage, or attempts to communicate with suspicious servers.

Identifying Hidden Threats with Omnis

Omnis is particularly effective at identifying hidden threats that are difficult to detect using traditional methods. This includes:

• Lateral Movement Detection: Lateral movement is a technique used by attackers to move within a network after initial penetration. Omnis can detect lateral movement by tracking the movement of users and devices across the network and identifying unusual access patterns.
• C2 Traffic Detection: C2 traffic (Command and Control) is the communication between a compromised device and a control server used by an attacker to send commands and receive data. Omnis can detect C2 traffic by analyzing network traffic and identifying communications with known or suspicious C2 servers.
• APT Attack Detection: Omnis helps detect APT in the network by combining various behavioral analysis methods to identify complex and protracted attacks that can go unnoticed for extended periods.

Solving Specific Problems with Omnis

Omnis solves a number of key problems faced by information security professionals:

• Reducing False Positives: Omnis uses advanced machine learning algorithms to reduce false positives, allowing analysts to focus on real threats.
• Accelerating Incident Investigation: Omnis provides analysts with detailed information about incidents, including information about compromised users, devices, and data, enabling them to quickly investigate and remediate threats.
• Improving Overall Network Security: Omnis helps improve overall network security by identifying and neutralizing threats before they can cause serious damage.
