  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!
