Essential Cybersecurity Commands & Practices

1. Network Scanning with Nmap

nmap -sV -A target_ip 
nmap -p 1-1000 target_ip 

– -sV: Detects service versions.
– -A: Aggressive scan (OS detection, script scanning).

**2. Password Cracking with John the Ripper**

john --wordlist=/usr/share/wordlists/rockyou.txt hashed_passwords.txt 

– Use strong wordlists for better results.

**3. Metasploit Framework Basics**

msfconsole 
use exploit/multi/handler 
set payload windows/meterpreter/reverse_tcp 
set LHOST your_ip 
set LPORT 4444 
exploit 

**4. Analyzing Logs with Grep (Linux)**

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

– Detect brute-force attacks on SSH.

**5. Windows Security Checks**

Get-NetTCPConnection | Where-Object {$_.State -eq "Established"} 

– Lists active connections (useful for detecting malware).

**6. SQL Injection Testing with SQLmap**

sqlmap -u "http://example.com/page?id=1" --dbs 

– `–dbs` lists available databases.

**7. Encrypting Files with OpenSSL**

openssl enc -aes-256-cbc -salt -in file.txt -out file.enc 

– Decrypt with:

openssl enc -d -aes-256-cbc -in file.enc -out file.txt 

**8. Detecting Rootkits with chkrootkit**

sudo chkrootkit 

**9. Firewall Management (Linux)**

sudo ufw enable 
sudo ufw allow 22/tcp 

**10. Windows Event Log Analysis**

Get-WinEvent -LogName Security -MaxEvents 50 | Format-List 

### **What Undercode Say:**

Cybersecurity requires continuous learning and hands-on practice. These free courses provide a strong foundation, but real expertise comes from applying knowledge in labs, CTFs, and real-world scenarios. Always stay updated with new attack vectors and defensive techniques.

**Expected Output:**

• Improved cybersecurity skills.
• Hands-on experience with penetration testing tools.
• Better understanding of defensive mechanisms.
