Security software enhances computer and network security, performing functions such as virus detection, access filtering, and encryption. It can be customized and is available in various forms, from freeware to specialized programs. Reviews help consumers choose the best product.
Security software is computer software designed to enhance the security of a single computer or a network of computers. This software is intended to be used as part of a total security plan, rather than as a standalone security measure. Many software companies make security products, ranging from freeware that can be downloaded by individual computer users to special programs designed for particular networks, such as those used to store information for governments.
Security software can perform a variety of security functions. Some programs are designed for a single, specific purpose, such as spyware removal, while others can perform multiple functions. Security software is used to establish firewalls, detect and remove viruses, protect information on a network, detect attacks on a computer or network, and so on. As a rule, it works all the time, providing background protection, and users can also run utilities to scan their computers for specific malware.
Such software can also be used for access filtering. With some computers and networks, it may be useful to filter access to keep people away from sites that might threaten your security, such as sites that automatically initiate downloads of malicious code. Access filtering can also be used to ensure that people in the workplace only access sites that are appropriate for the job, and to protect young computer users such as children from material that may be threatening or dangerous.
Most programs are highly flexible. The program may have settings that ensure that only an administrator can perform certain tasks with the program, and the program can be configured to meet the needs of a specific system. You can also direct security software programs to issue reports that are sent to an administrator when problems are found. They can also be used to protect specific content on a particular computer; for example, someone can create password-protected files or directories with security software to limit unauthorized access.
The term “security software” is also used to describe cryptographic software. This software is used to send and receive encrypted messages, ensuring that even if a message is intercepted, it will not be readable. Truly robust cryptographic software that is extremely difficult to crack can be quite expensive and resource-intensive, while basic programs provide a low level of encryption for people who want moderately secure communications.
Security software reviews are available through many reputable websites and computer magazines. Such reviews discuss cost, ease of use, setup process, and other features to help consumers make an informed choice about which product will be best suited.
