Estimated read time 2 min read

Hello, cybersecurity warriors! Today we’re diving into an essential aspect of threat hunting: the detection of a monitored security event pattern. It’s a mouthful, isn’t it? But don’t worry, we’ll break it down into bite-sized pieces. Let’s get started!

What is it?

A monitored security event pattern, simply put, is a recurring sequence of security events that is tracked and analyzed. These patterns can range from failed login attempts to suspicious network activity. They’re like footprints in the digital sand, hinting at a potential intruder’s presence.

What does it mean?

When you spot a monitored security event pattern, it’s like an alarm bell going off. It’s a sign that something might be amiss in your system. These patterns can suggest a wide array of security threats – from malware infections to unauthorized access attempts, and even sophisticated cyber attacks.

Remember, these patterns don’t always spell disaster. Sometimes, they might just indicate a system glitch or a forgetful user who has attempted one too many wrong passwords. But the key is to stay alert and investigate.

What is Expected?

As a cybersecurity professional, you are expected to spot these patterns and respond swiftly. This means not just identifying the pattern but understanding what it might imply, and determining the best course of action. Swift detection can mean the difference between a minor hiccup and a major catastrophe.

This is where your expertise and judgement come into play. Remember, every pattern tells a story. Your job is to read that story and respond to it effectively.

Things to Search For

When hunting for event patterns, what should you be looking for? Here’s a quick rundown:

  1. Repeated login attempts: Multiple failed attempts can hint at a brute-force attack.
  2. Unusual network traffic: An unexpected surge can indicate a DDoS attack or data exfiltration attempts.
  3. Unexpected system changes: Unauthorised modifications can suggest an intruder in the system.
  4. Unusual user behavior: If Bob from accounting is suddenly accessing confidential files at 3 am, it might be worth investigating.
  5. Anomalies in log files: Discrepancies or changes in logs can be a sign of an attacker covering their tracks.

Remember, folks, detection is just the first step. Once you’ve spotted a pattern, it’s all about swift, effective response. Keep those eyes peeled, and happy hunting! Stay safe out there in the cyber wilderness.
