Hey everyone,
I'm currently learning cybersecurity and put together a small list of Linux commands that I find useful for basic security and network analysis.
1. ss -tulpn
Check listening TCP/UDP ports and associated processes.
2. ss -tunap
View active network connections and associated processes.
3. ip addr
Display network interfaces and IP addresses.
4. ip route
Display the routing table.
5. sudo lsof -i
Show processes using network connections.
6. dig example.com
Perform DNS lookups.
7. ps aux
List running processes.
8. journalctl -u ssh
Review SSH service logs.
9. grep -i "failed" /var/log/auth.log
Search authentication logs for failed attempts.
10. sudo tcpdump -i eth0
Capture network traffic for analysis.
These are simple commands, but I think they are useful for beginners learning Linux and cybersecurity.
What other commands would you recommend adding?
