Documentation, investigations, and technical tutorials based on the cybersecurity lab practices.
In this lab, I used Nmap to identify open ports on a Linux server, investigated the exposed services with lsof, and linked the discovered ports to running Docker containers.
In this lab, I used Wireshark to capture and analyze network traffic between my MacBook and a Linux server, observing ICMP packets, SSH connections, TCP handshakes, and traffic generated by an Nmap scan.
In this lab, I analyzed SSH authentication logs on Ubuntu using journalctl, identifying successful logins, session opening and closing, failed password attempts, and connection source IPs.
A practical deep dive into managing firewall rules (UFW) in Linux, exploring how protocols and ports relate to protecting a network environment.
In this lab, I configured remote SSH access between a MacBook and an Ubuntu machine on the local network. The goal was to practice concepts of IP, ports, SSH service, UFW firewall, and connectivity diagnostics.
