| Malicious code includes viruses, worms, Trojan horses, and spyware. It can be transported by electronic mail, mail attachments, web accesses, removable media, or other common means. Malicious mobile code is a vehicle to remotely install malware on a computer. This type of code can be transmitted through interactive web applications such as ActiveX controls, Flash animation, or JavaScript. The code provides the ability for a malicious user to read from and write to files and folders on a computer's hard drive. They also have the ability to run and attach programs, which provides a high risk potential for the distribution of malicious mobile code. The black hats and malicious code writers continuously find new methods to attack hosts and the network infrastructure. It is imperative that new protection mechanisms developed to mitigate their risks must be installed as quickly as possible. For the IDPS, rules are also updated to detect attempts to exploit systems. Not updating the rule sets could lead to missed reconnaissance and malicious attacks. |
