Computer System Security and Access Control


computer system security

Computer system security is a group of measures designed to protect computers from various computer-related attacks. This includes things like intrusion detection systems (IDS/IDS) and firewalls, protected networks, privacy alarms, virtual private servers, backups, and secure systems. All of these things are aimed at preventing the intentional or unintentional access of a computer system by an unauthorized party. Some common types of attacks include exploits (a technique used to allow an authorized user on a computer system), malware (programs designed to cause excessive network traffic), and viruses.

As a result, computer system security is about more than just preventing software vulnerabilities. It also involves reducing or eliminating the opportunities for vulnerability because of poor programming assignments, configuration errors, or lack of training. The goal of any IT project is to have a working final project that is free of vulnerabilities so that no one has to be in harm’s way in the process of fixing the system.

The primary component of any computer security system is the update and upgrade of its virus definitions. Viruses, spyware, worms, and Trojans are some of the most malicious sorts of intruders. They are designed to do immense damage. In fact, they can wipe out a hard drive or render an entire computer unusable. When a company invests in its own up-to-date patches for its operating system, the threat of these malicious intruders is reduced considerably.

Another important element of computer security is the education of users. A good antivirus program should instruct users on how to update their virus definitions on a regular basis. In fact, that is one of the best ways of reducing the opportunities for vulnerability. Any computer system security software that doesn’t allow update is an invitation to criminals to make use of that system. The safest software programs will allow a user to download and install updates on a schedule, just like they would with a Windows or Office program.

A final aspect of protection is access control. Just as it’s important to update virus definitions and run regular updates, it’s equally important to properly secure the perimeter of a network. Common methods include setting up password-protected areas on the network and applying what is called an intrusion detection and response plan. These plans can include detection of known software vulnerabilities and blocking them before they are able to cause damage. They can also block access from unauthorized computer systems.

A Much Ado

Passwords provide a great deal of protection for computer security systems. However, passwords, whether simple or complex, must be protected from unauthorized use. Changing your passwords regularly is the best way to do this. Moreover, there are some data security passwords that are impossible to hack; these include bank account numbers, credit card numbers, and passwords that have been used on websites.

Data security passwords and access control systems can also be quite effective when combined. For example, there are times when you want to restrict access to specific areas of a network. You might want to limit the access of your computer to specific employees or even to the specific network itself. In such cases, using data security passwords and controls can help achieve both of these goals simultaneously.

Bottom Line

The combination of up-to-date anti-spyware programs and computer security software presents another option for protecting your network. Spyware is software that collects information about how you use your computer and sends it back to a third party. Most often, these programs are designed to track your Internet activity so that advertisers can send you ads based on the types of sites that you visit, your age, or the language in which you speak. Although some spyware programs are very helpful, many are designed to collect personal information about you and send this information back to advertisers. If you are concerned about the security of your computer system, you can download certain types of anti-spyware programs that will keep track of any files containing personal information and alert you each time such files are accessed. Using this type of software is the most effective way to ensure the safety of your personal files containing information that you wish to keep private.
