“Malware,” also known as malicious software or code, is software that is installed on computers often without an operator's knowledge or without knowledge of the full intent of its purpose. Typically used for some type of abusive behavior, malware is capable of gathering information that leads to loss of privacy or exploitation, disrupting or denying operation, and gaining unauthorized access to system resources. Common types of malware include: Trojans, Viruses, Worms, Adware, Backdoors, and Spyware. These often deliver a “payload” or program that performs a malicious action on the infected system.
This form of attack can greatly
impact a computer used to control critical assets in the nation’s infrastructure. There are many malware prevention techniques, including antivirus software and intrusion detection and prevention. Another, patch management, involves establishing a frequent security update process for all installed applications and firmware on the network. All are effective approaches to prevent malware exploitation, but none are "bulletproof" or sufficient as stand-alone solutions.
FoxGuard Solutions recommends layered protection to secure industrial control systems. Beginning with DisPatch or DisPatch ProNet, FoxGuard applies antivirus and host intrusion detection software and provides validated security updates on a periodic basis. It also defends the network using firewalls and intrusion detection devices.
