Frequently asked questions

Burp Suite, OWASP ZAP (web security), Wireshark (networking), Nmap (scanning), Metasploit (pentest), Hashcat/John (passwords), OpenSSL (cryptography), Snort/Suricata (IDS). Languages: Python, C, Java.

So, each course on cyber security includes a practical implementation: demonstration of an attack, implementation of protection, cryptographic algorithm or configuration of security tools.

We provide instructions for setting up the environment. Most tools are free (Kali Linux, OWASP ZAP, Wireshark). For some topics, we use Docker containers for isolation.

Theoretical part (review of threats, protection methods), practical implementation (code/configuration), testing, analysis of results, recommendations, documentation.
