In this tutorial I will show you guys how to secure your PC in 10 steps, I recommend you read this article carefully and be safe.

Choose the right operating system

1- Choose an operating system based on its security and vulnerability (Linux has no known active virus in the wild, OpenBSD is security-oriented). Find out if it uses limited user accounts, all file permissions, and if it is regularly updated. Be sure to update your operating system with security updates, and update your other software as well.

Choose the right web browser

2- Choose a Web browser based on its security and vulnerabilities, because most malware will be transmitted through your Web browser. Also disable scripts (NoScript, Privoxy and Proxomitron can do this). Look at what independent IT security analysts (such as US-CERT) and crackers (similar to hackers) are saying. Google Chrome [1] is more secure and has a sandbox function [2]. It would therefore be more difficult to compromise the system and spread the infection.

Use strong passwords

3- When configuring, use strong passwords on your user account, your router account, etc. Hackers can use dictionary attacks and brute force attacks.

Use reliable sources

4- Use reliable sources. When you download software (including antivirus software), get it from a reliable source (softpedia, download, snapfiles, tucows, fileplanet, betanews, sourceforge) or from your repository if you use Linux.

Install good antivirus software

5- Install good antivirus software (especially if you use P2P). Antivirus software is designed to handle modern malware, including viruses, Trojans, keyloggers, rootkits and worms. Find out if your antivirus software offers real-time, on-access or on-demand scanning. Also find out if it is heuristic. Avast [3] and AVG [4] are very good free editions. Choose one, download and install it and scan regularly. Keep your virus definitions up to date by updating them regularly.

6- Download and install spyware management software such as Spybot Search and Destroy, HijackThis [5] or Ad-aware [6] and scan regularly. I can't say it enough - you need to run a good anti-spyware and anti-malware program like Spybot if you search the web at all. Many websites exploit the weaknesses and security holes in Microsoft Explorer and place malicious code on your computer without you knowing it until it's too late!

Download and install a firewall

7- Download and install a firewall. ZoneAlarm [7] or Comodo Firewall [8] (Kerio, WinRoute or Linux comes with iptables). If you are using a router, this adds an extra layer of security by acting as a hardware firewall.

Close all ports

8- Close all ports. Hackers use port scanning (Ubuntu Linux has all ports closed by default).

Perform penetration tests

9- Perform penetration tests. Start with ping, then run a simple nmap analysis. Backtrack Linux will also be useful.

secure physical security

10- Don't forget to think in terms of physical security! Consider something like a Kensington lock (in case of theft / unauthorized access). Also set a BIOS password and prevent access to your machine or its removable devices (USB, CD drive, etc.). Do not use an external hard drive or USB device for important data.
