Security Software
With the constant threat of hackers and malicious viruses ready to damage and even destroy your computer files and programs, computer systems need the protection of security software to help them keep running fully and safely.
A vital form of security software is the anti-virus program. This software detects and isolates (or even destroys, depending on the program) malicious viruses that try to attack computer systems either from media (CD-ROMs, floppy discs, etc.) or, more often, from the internet (often, though not always, attacking through attachments to electronic mail.) As there are always new viruses being created…and some of the existent viruses actually mutate as they spread…it is essential that anti-virus software be updated on a regular basis so that it may better perform the task for which it was created. Firewalls are a form of security software that attempt to provide protection to systems by disallowing traffic (from the internet or from within the system itself) that does not confirm to a specific set of pre-determined guidelines. Firewalls can range in size from those designed to protect a single personal computer up to those meant to safeguard entire mainframe setups. Firewalls are an essential first line of defense for computer systems. A growing field of concern for security software is spyware removal. Spyware is hidden programs (sometimes called “Trojans” for the fabled Trojan Horse) that can invade a system and allow hackers to monitor that system, steal information from it or even destroy it. Spyware removal programs can ferret out the invaders and prevent them from compromising systems and/or information or from doing harm. Pests, a catch-all term for computer system threats other than viruses, can be better managed with a layered defense strategy of pest control programs. In addition to spyware and other Trojan Horses, these can include hacker tricks to try to compromise or control a system (such as logging keystrokes or attempting to discern personal passwords), malicious “mail bombs” (code designed to disable or even destroy systems) and the like. Pests are not necessarily caught by anti-virus software and need to be rooted out with security software specifically designed to detect and eradicate them. Encryption programs are a form of security software that attempts to frustrate attempts at hacking a system or stealing information from it by storing, managing, and transmitting data in coded formats that are difficult to decode. If computer security is breached despite the best efforts available, reliable data backup is another form of security software that is essential to the timely and complete recovery of a lost or damaged system.
