You Should Know:
1. Essential Cybersecurity Commands (Linux/Windows)
- Network Scanning (Nmap)
nmap -sV -A target_ip
Scans for open ports, services, and OS detection.
- Password Cracking (John the Ripper)
john --format=sha256crypt hashed_passwords.txt
-
Windows Firewall Rule (Block IP)
New-NetFirewallRule -DisplayName "Block Malicious IP" -Direction Inbound -RemoteAddress 192.168.1.100 -Action Block
2. Vulnerability Assessment
- Nikto Web Scanner
nikto -h https://example.com
- Metasploit Framework
msfconsole use exploit/multi/handler set payload windows/meterpreter/reverse_tcp
3. Secure File Transfer (SCP)
scp -P 22 user@remote:/path/to/file /local/destination
4. Log Analysis (Linux)
grep "Failed password" /var/log/auth.log
Identifies brute-force attempts.
What Undercode Say
Cybersecurity education is incomplete without hands-on practice. Mastering tools like Nmap, Metasploit, and John the Ripper is crucial. Always:
– Update systems (sudo apt update && sudo apt upgrade).
– Encrypt sensitive data (openssl enc -aes-256-cbc -in file.txt -out file.enc).
– Monitor logs (journalctl -xe).
Expected Output:
Starting Nmap 7.92 ( https://nmap.org ) Nmap scan report for target_ip 22/tcp open ssh OpenSSH 8.2p1 Ubuntu 4ubuntu0.3 (Ubuntu Linux; protocol 2.0)
