You Should Know
1. Essential Linux Commands for Cybersecurity
Command:
sudo nmap -sS -T4 -A -v target_IP
What It Does:
This Nmap command performs a stealth SYN scan (-sS), aggressive timing (-T4), OS and service detection (-A), and verbose output (-v) to analyze a target network.
Step-by-Step Guide:
1. Install Nmap:
sudo apt install nmap Debian/Ubuntu sudo yum install nmap RHEL/CentOS
2. Run the scan:
sudo nmap -sS -T4 -A -v 192.168.1.1
3. Analyze open ports, services, and potential vulnerabilities.
2. Windows Security: Detecting Suspicious Processes
Command (PowerShell):
Get-Process | Where-Object { $_.CPU -gt 90 } | Select-Object ProcessName, Id, CPU
What It Does:
This PowerShell command identifies high-CPU-usage processes, which could indicate malware or unauthorized activity.
Step-by-Step Guide:
1. Open PowerShell as Administrator.
- Execute the command to list processes consuming over 90% CPU.
- Investigate suspicious processes using Task Manager or
Stop-Process -Id</code>. </li> </ol> <h2 style="color: yellow;"> 3. Securing SSH on Linux</h2> <h2 style="color: yellow;">Command:</h2> [bash] sudo nano /etc/ssh/sshd_config
What It Does:
This opens the SSH configuration file for hardening.
Step-by-Step Guide:
1. Disable root login:
PermitRootLogin no
2. Restrict authentication methods:
PasswordAuthentication no PubkeyAuthentication yes
3. Restart SSH:
sudo systemctl restart sshd
4. Detecting Open Ports with Netstat (Windows/Linux)
Windows Command:
netstat -ano | findstr LISTENING
Linux Command:
netstat -tuln
What It Does:
Lists all listening ports, helping identify unauthorized services.
Step-by-Step Guide:
- Run the command in CMD (Windows) or Terminal (Linux).
2. Check for unexpected open ports.
- Investigate using `tasklist` (Windows) or `ps aux` (Linux).
5. API Security: Testing for Vulnerabilities
Command (Using OWASP ZAP):
docker run -v $(pwd):/zap/wrk/:rw -t owasp/zap2docker-stable zap-baseline.py -t https://example.com
What It Does:
Scans a web API for OWASP Top 10 vulnerabilities.
Step-by-Step Guide:
1. Install Docker.
- Run the command, replacing `https://example.com` with your target.
3. Review the generated report for security flaws.
