Linux Security Monitoring and Threat Detection Masterclass | TryHackMe | SOC Level 1 2025
This mega‑video combines four essential TryHackMe rooms into a complete introduction to Linux Security Monitoring. According to the module description, you’ll learn how Linux logging works, how attackers compromise Linux systems, and how SOC analysts detect malicious activity using log analysis, process‑tree reconstruction, and system‑level forensics.
We begin with Linux Logging for SOC, where you learn how Linux logs are structured, where they are stored, and how to analyze syslog, auth.log, kernel logs, dpkg logs, and bash history. You’ll explore how authentication events, system changes, and runtime activity appear in Linux telemetry, and how auditd provides deep visibility into process execution.
Next, we move into Linux Threat Detection 1, focusing on Initial Access. You’ll analyze SSH authentication logs, detect brute‑force attempts, investigate compromised logins, and examine how attackers exploit web‑service vulnerabilities to execute commands. You’ll also learn how to use process‑tree analysis to trace the origin of malicious activity.
From there, we explore Linux Threat Detection 2, where you detect the attacker’s post‑compromise activity. You’ll investigate privilege‑escalation attempts, credential‑access behavior, unauthorized file access, and persistence mechanisms such as cron jobs, startup scripts, and modified SSH configurations. You’ll also learn how attackers evade detection by altering logs or disguising processes.
Finally, we dive into Linux Threat Detection 3, where you analyze Command‑and‑Control, persistence, and malware behavior. You’ll identify suspicious outbound connections, hidden binaries, malicious startup modifications, and long‑term persistence strategies. You’ll learn how SOC analysts correlate logs, processes, and file‑system artifacts to uncover C2 activity and reconstruct the attacker’s full persistence chain.
🔍 What you’ll learn:
• How Linux logs work and how to analyze syslog, auth.log, kernel logs, and auditd
• How attackers gain initial access via SSH and web‑service exploitation
• How to detect privilege escalation, credential theft, and unauthorized file access
• How persistence mechanisms appear in logs and process trees
• How attackers deploy and operate Linux C2 malware
• How SOC analysts investigate Linux intrusions end‑to‑end
