Deep Packet Inspection (DPI) in Omnis: Unmatched Threat Visibility

In an era where the cyber threat landscape is becoming increasingly complex, and attackers have mastered the art of hiding their activities in encrypted traffic, traditional protection methods are no longer sufficient. Critical data slips through gaps in defenses while security systems stand idle. The only solution is DPI for security, providing deep traffic analysis at the application layer. Omnis by NWU is a powerful solution that gives you exactly this capability, providing L7 application visibility and allowing you to effectively detect and block even the most sophisticated attacks.

Why is Deep Packet Inspection security necessary today?

The growth of encrypted traffic (SSL/TLS) poses serious challenges for traditional security systems. Attackers actively use encryption to hide malicious traffic, which bypasses outdated protection mechanisms unhindered. Standard firewalls and intrusion detection systems (IDS) are often unable to detect threats hidden in encrypted packets. DPI for security is becoming a critical tool for ensuring adequate protection, allowing you to analyze the contents of packets and identify anomalies, regardless of encryption.

Benefits of DPI in NDR

Network Detection and Response (NDR) solutions are gaining popularity as they provide a comprehensive approach to detecting and responding to threats on the network. The benefits of DPI in NDR are as follows:

• How DPI Helps Identify Threats in SSL/TLS Traffic: DPI allows you to decrypt SSL/TLS traffic (in compliance with privacy policies) and analyze its contents for malicious signatures, exploits, and other anomalies.
• Improved Threat Detection: DPI enables the detection of attacks that use sophisticated evasion techniques such as tunneling and obfuscation.
• More Accurate Analytics: DPI provides more complete information about network traffic, allowing you to analyze user and application behavior, identify suspicious activity, and respond to incidents in a timely manner.
• Accelerated Incident Response: With a deeper understanding of traffic, DPI helps quickly identify the source and scope of an attack and take the necessary steps to neutralize it.

Omnis: Next-Generation DPI for security

Omnis is a network security platform developed by NWU that uses advanced DPI for security technologies, providing unmatched visibility and control over network traffic. Omnis offers a wide range of capabilities for threat detection and prevention, including:

Deep Packet Inspection security: Technologies Behind Omnis

At the heart of Omnis is a high-performance Deep Packet Inspection engine that is capable of analyzing traffic in real-time without significantly impacting network performance. Omnis uses:

• Signature Analysis: Detection of known threats based on signatures of malicious code, exploits, and other indicators of compromise.
• Behavioral Analysis: Identifying abnormal behavior of users and applications that may indicate the presence of threats.
• Heuristic Analysis: Detection of new and unknown threats based on analysis of traffic characteristics and identification of suspicious patterns.
• Encrypted Traffic Analysis (ETA): Omnis effectively analyzes encrypted traffic, identifying threats hidden within SSL/TLS connections without the need to decrypt all traffic.

L7 Application Visibility: Control Over Applications on the Network

Omnis provides detailed information about the applications used on the network, allowing you to:

• Identify Applications: Omnis automatically identifies thousands of different applications, including web applications, cloud services, P2P networks, and more.
• Control Application Usage: Omnis allows you to set application usage policies, restrict access to certain applications or categories of applications, and block unwanted traffic.
• Optimize Network Performance: Omnis helps identify applications that consume a lot of traffic or create performance problems, allowing you to take steps to optimize network performance.

Encrypted Traffic Analysis (ETA): Solving the Encryption Problem

Encrypted Traffic Analysis (ETA) in Omnis is a multi-layered approach to detecting threats in encrypted traffic. Instead of relying solely on decryption, which can be resource-intensive and create privacy concerns, Omnis uses:

• Metadata Analysis: Omnis analyzes packet headers, SSL/TLS certificates, and other information to identify suspicious activity.
• Statistical Analysis: Omnis analyzes statistical characteristics of traffic, such as packet size, connection frequency, and traffic distribution over time, to identify anomalies.
• Threat Intelligence Integration: Omnis uses information about known malicious domains, IP addresses, and certificates to identify threats in encrypted traffic.

Solving Specific Problems with Omnis

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

• Detecting Malware in Encrypted Traffic: Omnis allows you to identify malware that hides in SSL/TLS connections and prevent its spread across the network.
• Preventing Data Leaks: Omnis helps prevent leaks of sensitive data by identifying and blocking data transmission through unauthorized channels.
• Protection Against DDoS Attacks: Omnis detects and blocks DDoS attacks that use encrypted traffic to overload the network.
• Compliance with Regulatory Requirements: Omnis helps organizations comply with various regulatory requirements, such as PCI DSS and HIPAA, by providing visibility and control over network traffic.

Benefits of Implementing Omnis with DPI for security

Implementing Omnis with advanced DPI for security technology provides organizations with the following benefits:

• Improved Visibility: Omnis provides complete L7 application visibility and allows you to control all network traffic, including encrypted traffic.
• Enhanced Protection: Omnis detects and prevents a wide range of threats, including malware, data leaks, and DDoS attacks.
• Increased Efficiency: Omnis automates many tasks related to network security, allowing security professionals to focus on more important tasks.
