Computer Security Basics

Preventing hackers from invading your business or personal computer is a necessary measure with today’s security threats and risks. Data integrity is an important factor in safeguarding sensitive information, as well as keeping track of records and valuable personal information. Virus protection is a necessity with the multitude of threats and hacks that are threatening computers and networks daily. Computer security involves minimizing these risks as much as possible, with a few key strategies and techniques.

Maintaining the physical security of the computer and network devices is the first step. This can be as simple as locking a room, or turning off a computer that has been setup with administrator password. Physical security can be further improved to prevent computer hardware from natural damage, and even equipped with sound alarms in case of an invasion of the area. Surge protectors will prevent data disruptions that can leave a computer or network in a very vulnerable condition. These are just a few ways that hackers can tap into your computer or network, and implementing effective physical security strategies can help you take preventative action.

Backing up data on a regular basis is the second step of computer security. Here, a log file and records need to be locked away with all necessary data and files, and this needs to be updated and even encoded for sensitive information. Data security is more important today with the sensitive nature of the files and information that are becoming more common across thousands of industries. Personal information such as credit card numbers, social security numbers, pin codes and banking information are stored on many computers and may be accessed by the wrong party. Hackers may ‘crack’ into different databases to extract this information, but there are still preventative measures available to help with maintaining a high level of security. Firewalls, intranet password systems, and verifying audit trails can help in reducing the risks of various attacks.

Installing spyware protection programs is the third step. A number of antivirus and software scanning options are available, and these can help reduce computer security risks considerably. Many Trojans and spyware programs are installed automatically through security flaws on the user’s computer. Manually removing them may prove difficult, but a variety of anti-spyware and antivirus programs can manage and tap into these files consistently. Pop-up blocking software is another useful tool that can prevent unnecessary or unauthorized downloading.

In addition to the basic computer security measures, there are a few more simple ways to reduce the risk of a hack attack. First, internet connections should be installed with adequate firewalls, as these can prevent intruder access over a network. Frequent virus checking, whether this is through a scanning software program or periodical checks through a program online are recommended to maintain the computer’s health. Backing up files and storing them in a safe place will ensure that any problems that do occur can be fixed immediately. Finally, ensuring that passwords are changed frequently can help with administrator controls; it will be more difficult for passwords to be stolen and used if the user is continually changing them and not sharing this sensitive information in any form.
