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.
