 Strengthening Your Computer Security with Command Prompt (CMD) Commands

In an age where digital threats loom large, ensuring the security of your computer is paramount, especially when you're browsing websites. Whether you're an individual user or a business owner, taking steps to enhance your computer's security can safeguard your sensitive data and online activities.

Computer Security with Command Prompt (CMD) Commands

Disclaimer: While these steps can enhance your computer's security, there's no such thing as absolute security in the digital realm. Stay updated with the latest security practices and consider consulting a cybersecurity expert for specific needs.

Mastering Computer Security: The Power of CMD Commands

1. Enable Windows Firewall

Windows Firewall acts as the first line of defense against incoming and outgoing network traffic. To enable it, open CMD as an administrator and run the following command:

shell
netsh advfirewall set allprofiles state on

2. Update Windows and Software

Regularly updating your operating system and software is crucial. Outdated software can contain vulnerabilities that hackers exploit. Run these commands to check for updates:

shell
schtasks /run /tn "\Microsoft\Windows\WindowsUpdate\Automatic App Update"

shell
schtasks /run /tn "\Microsoft\Windows\WindowsUpdate\Automatic Maintenance"

3. Check Active Network Connections

Use the netstat command to view active network connections. Look for any suspicious connections that might indicate malware or unauthorized access:

shell
netstat -ano

4. Flush DNS Cache

Clearing the DNS cache can help prevent DNS spoofing attacks:

shell
ipconfig /flushdns

5. Reset Network Settings

If you suspect network-related issues, you can reset your network settings using these commands:

shell
netsh winsock reset
netsh int ip reset

6. Monitor System Activity

Use the tasklist command to view running processes and taskkill to terminate suspicious ones:

shell
tasklist
taskkill /F /IM processname.exe

7. Run a Malware Scan

Windows Defender, the built-in antivirus, can be initiated from CMD with this command:

shell
start msmpeng.exe

8. Harden Browser Security

Consider using a more secure browser and adjusting its settings. For example, for Google Chrome, you can create a shortcut with the following command and then modify its properties to add flags:

shell
"C:\Program Files\Google\Chrome\Application\chrome.exe" --disable-extensions --disable-plugins --no-sandbox --disable-web-security --disable-sync

9. Enable Two-Factor Authentication

Whenever possible, enable two-factor authentication (2FA) for your online accounts. This adds an extra layer of security.

10. Regularly Backup Your Data

Use a CMD command  robocopy to create regular backups of your important files:

shell
robocopy source destination /E /ZB /DCOPY:T /MIR /R:10 /W:5

Remember that cybersecurity is an ongoing process. Stay vigilant, update your system and software, and follow best practices. Additionally, consider using a reputable antivirus program, and a VPN, and practicing safe browsing habits to enhance your computer security when interacting with websites.
