To fully benefit from this training, we recommend having a good hands-on experience in administering Windows infrastructure and at least 8 years experience in the field.

 Target Audience

This is an advanced course on Linux Security and Hardening for Cybersecurity Specialists.

The course is perfect for enterprise administrators, infrastructure architects, security professionals, systems engineers, network administrators, IT professionals, security consultants and other people responsible for implementing network and perimeter security.

 

This Live Virtual Class consists of 8 Modules in terms of Advanced Linux Security and Hardening. They include essential theory combined with individual practice during the exercises as well as loads of hands-on tools and real-case scenarios.

Module 1: Mastering Discretionary Access Control (DAC)

  1. Understanding Linux permission models and ownership
  2. Configuring file and directory permissions with chmod, chown, and umask
  3. Managing privilege separation between users and processes

Module 2: Access Control Lists and Shared Directory Management

  1. Implementing fine-grained permissions with ACLs
  2. Managing collaborative and shared directories securely
  3. Auditing and verifying ACL configurations

Module 3: Implementing Mandatory Access Control with SELinux and AppArmor

  1. Understanding the difference between DAC and MAC
  2. Configuring SELinux policies for process confinement
  3. Using AppArmor profiles for application-level restrictions

Module 4: Kernel Hardening and Process Isolation

  1. Applying kernel security parameters (sysctl)
  2. Isolating processes and namespaces for security
  3. Mitigating privilege escalation risks and system exploitation

Module 5: Scanning, Auditing, and Hardening

  1. Conducting system audits using Lynis, OpenSCAP, and similar tools
  2. Identifying and remediating configuration weaknesses
  3. Automating compliance checks and system hardening

Module 6: Logging and Log Security

  1. Configuring rsyslog and journald for centralized logging
  2. Securing log files and preventing tampering
  3. Implementing log rotation and retention policies

Module 7: Vulnerability Scanning and Intrusion Detection

  1. Using vulnerability scanners such as OpenVAS or Nessus
  2. Deploying host-based intrusion detection systems (HIDS)
  3. Analyzing alerts and responding to detected threats

Module 8: Prevent Unwanted Programs from Running

  1. Applying application whitelisting techniques
  2. Restricting execution paths and user-level binaries
  3. Monitoring unauthorized or suspicious processes

Certification

After finishing the course, you will be granted a CQURE Certificate of Completion. Please note that after completing the course you will also be eligible for CPE points!
