HTTP Spyware and Grayware Scan Rules

HTTP > Advanced Threat Protection > Policies | Policy List | Spyware/Grayware Scan Rule

Spyware, phish, and other so-called grayware threats are beginning to surpass viruses, Trojans and worms in terms of prevalence and risk level. IWSVA can help enforce your right to prevent unwanted or unauthorized software from entering your network. In addition, you can break down your "virus" reports by threat type, and IWSVA can take different actions according to the threat type.

The following is a list of related topics:

• Spyware—High prevalence. MORE>>

  Spyware is software that can monitor a user’s computing habits and personal information, such as credit card numbers and passwords. Spyware can track a user's keystrokes and send this information back to the author without the user’s authorization or knowledge. Not all spyware is that pernicious, however. Web browser cookies that track Web hits for targeted marketing, are also considered spyware.

• Dialers—Low to medium prevalence. MORE>>

  Dialers, or "phone home" programs, are Trojans. Upon execution, a dialer tries to connect the system to a pay-per-call location without the user's knowledge or consent. Dialers often arrive in porn-related or other enticing service-related applications, and can run up large phone bills for the victim.

• Hacking tools—Low prevalence. MORE>>

  Hacking tools include programs that can be used by IT administrators to test their network's vulnerability or their susceptibility to attacks. Whereas in this context, these programs are legitimate; they can be downloaded from rouge sites by users who want to use the powerful programs for malicious purposes.

• Password cracking applications—Low prevalence. MORE>>

  Like hacking tools, password crackers are malicious tools designed to seek out weak passwords, generally poor security, or to mine valuable data.

  In the context of IT use, these programs are usually considered legitimate. In the wrong hands, however, they can create significant security concerns.

• Adware—High prevalence. MORE>>

  Adware is a software application that displays advertising banners while the program is running. Adware often contains spyware for the program to establish which advertisements to display based on the user’s Web surfing habits.

• Joke programs—Low prevalence. MORE>>

  Joke programs are ordinary executable programs, often written for the amusement of the recipient. Network administrators do not want joke programs to enter their systems, because these programs take up precious network bandwidth and might affect employee work performance.

• Remote access tools—Low prevalence. MORE>>

  This class of software enables the user to gain remote access to network clients or even servers. After access is gained, the user is often able to perform a variety of computing tasks, including complete control of the system. Like other programs of this type, these have the potential for both legitimate and illegitimate use.

• Others—Low prevalence. MORE>>

  This is used as an umbrella category to include newly emerging threats that do not fit into any of the existing categories. In other words, it is simply a catch-all for a variety of unique or undefinable threats.
