Document Summary

Integrity refers to the soundness of your network"s files, systems, and connections. To ensure their integrity, you must protect them from anything that might render them unusable, such as corruption, tampering, natural disasters, and malware. Availability refers to how consistently and reliably a file or system can be accessed by authorized personnel. Malware is any type of code that aims to intrude upon or harm a system or its resources. Malware includes viruses, worms, bots, and trojan horses. A virus is a program that replicates itself to infect more computers, either through network connections or through external storage devices passed among users. Viruses may damage files or systems, or simply annoy users by flashing messages or pictures on the screen or by causing the computer to beep. Any type of malware can have characteristics that make it hard to detect and eliminate. Such malicious code might be encrypted, stealth, polymorphic, or time dependent.
