You Should Know:

Cybersecurity awareness is critical in today’s digital world. Below are key commands, tools, and steps to enhance your cybersecurity practices:

1. Basic Linux Security Commands:

<h1>Check open ports</h1>

sudo netstat -tulnp

<h1>Monitor active connections</h1>

sudo ss -tunap

<h1>Check for rootkits</h1>

sudo rkhunter --check

<h1>Update all packages</h1>

sudo apt update && sudo apt upgrade -y 

#### **2. Windows Security Checks:**

<h1>List all active network connections</h1>

netstat -ano

<h1>Check firewall status</h1>

netsh advfirewall show allprofiles

<h1>Scan for malware using Windows Defender</h1>

Start-MpScan -ScanType FullScan 

#### **3. Digital Hygiene Practices:**

• Use 2FA everywhere possible.
• Regularly audit installed software:

  </li>
  </ul>
  
  <h1>Linux</h1>
  
  sudo apt list --installed
  
  <h1>Windows</h1>
  
  wmic product get name,version 
  

  – Encrypt sensitive files:

  
  <h1>Using GPG in Linux</h1>
  
  gpg -c secret_file.txt 
  

  #### **4. Phishing & Social Engineering Defense:**

  • Verify URLs before clicking:

    </li>
    </ul>
    
    <h1>Use curl to inspect headers</h1>
    
    curl -I https://example.com 
    

    – Check email headers for spoofing:

    Received: from mail.server.com (verified SPF/DKIM) 
    

    #### **5. Password Security:**

    • Generate strong passwords:

      openssl rand -base64 16 
      

    • Use a password manager like KeePassXC (Linux/Windows).

    ### **What Undercode Say:**

    Cybersecurity is not just about tools—it’s about habits. Regular audits, encryption, and skepticism toward unsolicited messages are key. Automation helps:

    
    <h1>Schedule daily security updates (Linux)</h1>
    
    sudo crontab -e 
    0 3 * * * apt update && apt upgrade -y 
    

    For Windows, use **Task Scheduler** for periodic scans.

    ### **Expected Output:**

    Active Internet connections (servers and established) 
    Proto Recv-Q Send-Q Local Address Foreign Address State 
    tcp 0 0 0.0.0.0:22 0.0.0.0:* LISTEN 
    

    Stay vigilant, update often, and verify before trusting.
