About the course
The course was offered by the International CyberSecurity Institute in the UK. Its 13 modules covered network threats and defences, as well as security policies, physical security and recovery.
My experience
I completed all 13 modules alongside other commitments, so it took me longer than I expected. The material worked well for building up from the basics, and each module included a quiz.
One detail I found odd: the certificate says “Certificate of Attendance”, even though passing the quizzes was part of completing the course.
Course modules
- Introduction to network security.
- Types of attacks.
- Firewalls.
- Intrusion detection systems.
- Encryption.
- Virtual private networks.
- Operating system hardening.
- Malware and defences.
- Security policies.
- System security assessment.
- Security standards.
- Physical security and recovery.
- Attacker techniques.
The course helped me build a broader understanding of network security beyond web application testing. I found the module-by-module structure manageable around my other work.
