WHO TEACHES THIS
About
Learn Security Management is written and taught by Gagan V Singh, a cybersecurity professional and educator based in London, United Kingdom. The premise is simple: you pass the CISSP by understanding the material, not by memorising question banks. Every guide here explains the concept first and the exam angle second.
The person behind it
Gagan founded Learn Security Management to give back to the cybersecurity community. It began as a YouTube channel sharing CISSP knowledge and grew into a full learning resource: in-depth written guides, realistic practice questions with clear explanations on the LSM practice-test platform, and direct support for candidates preparing for the exam.
He is a highly experienced, active practitioner in cybersecurity and Critical National Infrastructure protection, with a proven track record of securing complex, multi-million-pound CNI projects in the UK public sector. Learn the eight domains of information security from someone who applies CISSP principles daily in real-world, high-stakes environments, combining deep technical knowledge with strategic security leadership.
Credentials
Certifications held: CISSP, CCSP, PMP, and CompTIA Security+. That mix brings together cybersecurity, cloud security, project management, and risk governance: the same intersection the CISSP exam tests.
What Learn Security Management is for
The site covers the CISSP exam: identity and access management, security architecture, business continuity, and exam strategy, with a glossary of CISSP vocabulary defined the way the exam uses it. Articles favour clear explanations and real-world examples over rote lists, and every glossary entry is written to be genuinely useful on its own.
