1. Suricata – The IDS/IPS Engine 2. Zeek (formerly Bro) – The Network Analyzer Suricata vs. Zeek: Suricata tells you “I found a known bad thing.” Zeek tells you “here’s everything that happened on the network.” 3. Arkime (formerly Moloch) – The Packet Capture & Search How They Work Together Tool Primary Function Key Question

full comparison of Zeek vs Suricata vs Wazuh. The most important thing to understand is that Wazuh plays in a completely different category than Zeek and Suricata, though they complement each other very well. Quick Summary Table Zeek Suricata Wazuh Category Network traffic analyzer / NSM Network IDS / IPS / NSM SIEM / XDR

a clear breakdown of Zeek vs Suricata. The short answer is: they are complementary tools that solve different problems, and many security teams run both together.

Zeek is a single tool, while Security Onion is a full platform that includes Zeek. So they are not really direct competitors; it depends on the use case. What is Zeek? Zeek (formerly Bro) is an open-source, passive network traffic analyzer. Zeek Documentation In short, Zeek is like a very detailed surveillance camera for your

Part 1: The Role of SIEM in the SOC (The Architectural View) In a mature SOC, the SIEM performs four critical architectural functions: 1. Telemetry Aggregation & Normalization (The Data Lake) 2. Correlation & Detection (The Brain) 3. Investigation & Forensics (The Time Machine) 4. Compliance & Reporting (The Audit Trail) Part 2: The Evolution

Part 1: The Attack Surface (Critical Ports & Architectural Rules) Instead of a basic list, here are the most critical ports categorized by their architectural domain, along with the “Golden Rules” for securing them. 1. Identity & Infrastructure (The Crown Jewels) These ports manage authentication, directory services, and remote administration. If an attacker compromises these,

Part 1: Port Scanning (Lab, Detection, and Architecture) A port scan is the digital equivalent of walking through a neighborhood checking which doors and windows are unlocked. It is the primary tool used in the Reconnaissance and Weaponization stages of the Cyber Kill Chain. 1. The Types of Scans (What the SOC is looking for)

The 7 Stages of the Cyber Kill Chain 1. Reconnaissance (Gathering Intel) 2. Weaponization (Creating the Payload) 3. Delivery (Transmitting the Payload) 4. Exploitation (Triggering the Vulnerability) 5. Installation (Establishing a Foothold) 6. Command and Control (C2) (Two-Way Communication) 7. Actions on Objectives (The Endgame) The Modern Evolution: Limitations of the Traditional Kill Chain As

1. Advanced Threat & Attack Terminology (What the SOC is hunting) Modern attackers rarely use noisy, easily detected malware. The SOC must be trained to spot subtle, sophisticated techniques. 2. Advanced Detection & Investigation Concepts (How the SOC works) These terms describe the methodology of modern, proactive security operations. 3. SOC Leadership & Management Terminology

This is about understanding how the foundational network fabric dictates your security architecture, risk posture, and cloud strategy. 1. What is Networking? (The Security Leader’s Perspective) At its core, networking is the practice of connecting computing devices to share resources and communicate. However, in modern enterprise architecture, networking is the central nervous system of the
