Cybersecurity is not just about hacking, running scripts, or wearing a hoodie in a dark room. It’s a vast, complex field that requires a deep understanding of multiple disciplines.
Key Areas of Cybersecurity:
🔹 Risk and Compliance – Understanding laws (GDPR, HIPAA), policies, and securing businesses beyond just tech.
🔹 Defensive Security – Detecting threats (SIEM tools), responding to incidents (IR plans), and securing systems proactively.
🔹 Cloud Security – Securing AWS, Azure, and hybrid environments with IAM, encryption, and monitoring.
🔹 Threat Intelligence – Analyzing attacker TTPs (Tactics, Techniques, Procedures) using OSINT and dark web monitoring.
🔹 Penetration Testing – Ethical hacking (using tools like Metasploit, Burp Suite) is just one part.
