The Basics and Essentials of Computer Security

Most people don’t worry about computer security until they need to. Maybe malware has attacked and their PC now sits frozen and unusable. Or they have become a victim of identity theft and are busy cleaning up the mess. Other times people are overloaded with spam emails and spend countless hours (and dollars) trying to fix their machine, only to wind up in the same place again weeks later.

The information you store on the computer is valuable – to you and to those who want to steal or use it.  What you need is enough knowledge to create solid computer security and a tight system that will allow you the freedom to use computers as they were meant to be used.

What is Computer Security?

A secure computer is one that is under your control.  It is a PC that filters out unwanted files like malware and spyware.  It is a PC that protects your valuable data and keeps things encoded behind secure passwords.  A secure computer is one you can count on to work well each time you turn it on and to keep your information safe from hackers and attackers.

Basic Elements of Computer Security

There are two basic elements of computer security that you need to become familiar with. First are the tools and utilities you use to build a secure machine. Secondly, there are the ways in which you use your computer that allow you to avoid dangerous situations.

Computer Security Tools and Utilities

Antivirus and spyware protection are absolutely essential for any computer connected to the internet.  You will also need a firewall, preferably an external or network type that stands guard between your broadband device (such as a DSL or cable modem) and the Local Area network. 

These things will form the backbone of your security grid, but are also complimented by updated drivers and the latest versions of your operating system and software.  As difficulties and holes become known, developers introduce patches and fixes that provide you with more security and protection.  Be sure to stay current with the latest updates

Computer Security Best Practices

In many ways the problems with security and bogged down computer systems lies with the user and his/her habits. To provide the best computer security you need to develop good browsing and general use habits that offer less opportunity for attacks.

Watch what you download and ensure all files are obtained from a trusted source and scanned through your antivirus software first.  Be especially leery of executable files (ending with .exe).  Don’t open every email you get.  If you do not recognize the sender, be sure to delete it unopened right away.  For emails you do open, try not to click through the links directly.  Copy and paste or type the URL directly into your browser, since the link in the email body can be screened and take you virtually anywhere online.

Practice your ABC’s and Always Backup Consecutively.  That means you will need to establish a regular and scheduled method of backup that is recorded with a time and date stamp, allowing you to easily find the latest data if a crash or data contamination occurs.  With consecutive backups you can choose how far back you need to go and get your system up and running again quickly in the case of difficulty.

Computer security is something only you can provide well.  Be diligent about installing and using the tools and utilities that will provide good security and get in the habit of using these best practices.  That way you can rest easier knowing your computer and data are safe.
