How to secure your computer?

Keeping your PC secure is critical to protecting the personal, business, and financial information it contains. Computer security is important because it keeps your information protected. It's also important for your computer's overall health; proper computer security helps prevent viruses and malware, which allows programs to run quicker and smoother.

1.    1.   Keep your system and security up to date:- I know it’s annoying, but make sure you check your computer for updates. I’ve seen so many cases of computers that have never had any updates done to the operating system. Both Microsoft and Apple roll out updates regularly to their operating systems. These can be important security patches and you may be compromised if you don’t install them. When an update is available for your Operating System, you will get a notification. So you need to install them for your computer security.

2.     2  Enable Firewall :- Firewall is the barrier between a trusted system or network and outside connection. It filters the incoming and outgoing network traffic based on a user defined rules. In general, the purpose of a firewall is to reduce or eliminate the occurrence of unwanted network communications while allowing all legitimate communication to flow freely. In most server infrastructures, firewalls provide an essential layer of security that, combined with other measures, prevent attackers from accessing your servers in malicious ways. In every computer, the operating system comes up with a built-in firewall system. In windows, this can be found by navigating to Control Panel> System and security. If your Operating System doesn’t have firewall, a couple of free option are available in the internet.

3.     3.   Keep your password safe:-  It’s largely general knowledge that passwords are important. Using strong, random password is also very important. Be careful about saving password on application on your computer because some site save your password in plain text. You need to change your password frequently.

4.      4.  Use a VPN:-  VPN means Virtual Private network.  VPN is a excellent option for your security purpose, especially when browsing online. A VPN works by routing your device's internet connection through your chosen VPN's private server rather than your internet service provider (ISP) so that when your data is transmitted to the internet, it comes from the VPN rather than your computer. While using a VPN, all of your internet traffic is encrypted and tunneled through an intermediary server in a separate location. This masks your IP, replacing it with a different one, so that your ISP can no longer monitor your activity. A VPN can help you browse securely while using open wifi network and access censored material.

5.   5.    Use an antivirus:-  Antivirus is used to prevent, detect and remove malware. Antivirus software originally designed to detect and remove viruses from computer, can also protect from various malware. So keep your antivirus up to date.
