An effective awareness program explains proper rules of behavior for use of an organization's IT systems and information. Accordingly, awareness programs should include guidance to users on malware incident prevention, which can help reduce the frequency and severity of malware incidents. Organizations should also make users aware of policies and procedures that apply to malware incident handling, such as how to identify if a host may be infected, how to report a suspected incident, and what users need to do to assist with incident handling Ensuring the antivirus software alerts the users when malware is detected will ensure the user is informed of the incident and be able to more closely relate the incident to action being performed by the user at the time of the detection.System Administrator

While logging is imperative to forensic analysis, logs could grow to the point of impacting disk space on the system. In order to avoid the risk of logs growing to the size of impacting the operating system, the log size will be restricted. If the data in the log file exceeds the file size set, the oldest 20 percent of the entries are deleted and new data is appended to the file, so although the file size is restricted, it must also be large enough to retain forensic value.

Email has become one of the most frequently used methods of spreading malware, through embedded HTML code and attachments. User awareness and training, warning users to not open suspicious emails or email attachments and not clicking on hyperlinks, etc., from unknown or known senders, will not fully protect from email-borne malware. Mass mailing worms are similar to an email-borne virus but is self-contained rather than infecting an existing file. Protecting from email-borne viruses and mass mailing worms by scanning email upon delivery mitigates the risk of infection via email.System Administrator

Containment during a virus outbreak is crucial. Infected hosts may attempt to spread malware and will use every network path available to them when spreading that infection. By containing the system when a detection is found, the malware will be restricted to that one system. Likewise, if malware is detected in a shared folder, maintaining the connection between a system and the shared folder would allow the malware to spread. Placing temporary restrictions on network connectivity is an effective mitigation mechanism. These block connection settings will most often be used on a server housing shared folders and files, and will block the connection from any network user on a remote computer who attempts to read from, or write to, a threatened file in the shared folder. In addition, it will block the connection from any user on a remote computer who attempts to write an unwanted program to the computer.

Organizations should use centrally managed antivirus software that is controlled and monitored regularly by antivirus administrators, who are also typically responsible for acquiring, testing, approving, and delivering antivirus signatures and software updates through the organizations. (FISMA SP 800-83) Some processes are known to be higher risk, while others are low risk. By restricting policy configuration to the Default Processes policy, all processes will be interpreted equally when applying the policy settings and will provide the highest level of protection. Best practice dictates configuring Low Risk and/or High Risk policies only when it is necessary to improve system performance, and will focus the scanning where it is most likely to detect malware. There is risk associated with configuring the Low Risk and/or High Risk policies for the purpose of specifically excluding processes from scanning, and should only be done after evaluating other policy settings and determining risk.System AdministratorInformation Assurance Officer

Potentially Unwanted Programs (PUPs) include Spyware, Adware, Remote Administration Tools, Dialers, Password Crackers, Jokes, and Key Loggers. While PUPs do not typically have any infections capability on their own, they rely on malware or other attach mechanisms to be installed onto target hosts, after which they will collect and transfer data from the host to an external host and/or will be used as attach mechanisms. Configuring the antivirus software to attempt to clean the file first will allow for the possibility of a false positive.

An effective awareness program explains proper rules of behavior for use of an organization's IT systems and information. Accordingly, awareness programs should include guidance to users on malware incident prevention, which can help reduce the frequency and severity of malware incidents. Organizations should also make users aware of policies and procedures that apply to malware incident handling, such as how to identify if a host may be infected, how to report a suspected incident, and what users need to do to assist with incident handling. Ensuring the antivirus software alerts the users when a Buffer Overflow is detected will ensure the user is aware of the incident and be able to more closely relate the incident to action being performed by the user at the time of the detection.System AdministratorInformation Assurance Officer

Antivirus software vendors use collective intelligence from sensors and cross-vector intelligence from web, email, and network threats to compile scores that reflect the likelihood of whether a file in question is malware. The collective intelligence is constantly being updated, more frequently than the typical daily antivirus signature files. With File Reputation lookup, a more real-time response to potential malicious code is realized than with the local-running antivirus software, since by querying the cloud-based database when a file appears to be suspicious, up-to-the-minute intelligence is provided. This type of protection reduces the threat protection time period from days to milliseconds, increases malware detection rates, and reduces downtime and remediation costs associated with malware attacks. Using File Reputation lookup is mandated by US CYBERCOM on DoD systems.System Administrator

Email has become one of the most frequently used methods of spreading malware, through embedded HTML code and attachments. User awareness and training, warning users to not open suspicious emails or email attachments and not clicking on hyperlinks, etc. from unknown or known senders, will not fully protect from email-borne malware. Mass mailing worms are similar to an email-borne virus but is self-contained rather than infecting an existing file. Protecting from email-borne viruses and mass mailing worms by scanning email upon delivery mitigates the risk of infection via email.

This rule will block any common programs from running from the Temp directory; however, this rule is much more restrictive in that it stops nearly all processes from launching in the Temp folder. Most viruses need to be run once by a person before infecting a computer. This can be done in many ways, such as opening an executable attachment in an email or downloading a program from the Internet. An executable needs to exist on the disk before Windows can run it. A common way for applications to achieve this is to save the file in the user's or system's Temp directory and then run it. One purpose of this rule is to enforce advice that is frequently given to users: "do not open attachments from email." The other purpose of this rule is to close security holes introduced by application bugs. Older versions of Outlook and Internet Explorer are notorious for automatically executing code without the user needing to do anything but preview an email or view a website.

Hooking covers a range of techniques used to alter or augment the behavior of an operating system, of applications, or of other software components by intercepting function calls or messages or events passed between software components. Code that handles such intercepted function calls, events, or messages is called a "hook". Hooking can also be used by malicious code. For example, rootkits, pieces of software that try to make themselves invisible by faking the output of API calls that would otherwise reveal their existence, often use hooking techniques.

Antivirus software vendors use collective intelligence from sensors and cross-vector intelligence from web, email, and network threats to compile scores that reflect the likelihood of whether a file in question is malware. The collective intelligence is constantly being updated, more frequently than the typical daily antivirus signature files. With File Reputation lookup, a more real-time response to potential malicious code is realized than with the local-running antivirus software, since by querying the cloud-based database when a file appears to be suspicious, up-to-the-minute intelligence is provided. This type of protection reduces the threat protection time period from days to milliseconds, increases malware detection rates, and reduces downtime and remediation costs associated with malware attacks. Using File Reputation lookup is mandated by US CYBERCOM on DoD systems.

Email has become one of the most frequently used methods of spreading malware, through embedded HTML code and attachments. User awareness and training, warning users to not open suspicious emails or email attachments and not clicking on hyperlinks, etc., from unknown or known senders, will not fully protect from email-borne malware. Mass mailing worms are similar to an email-borne virus but is self-contained rather than infecting an existing file. Protecting from email-borne viruses and mass mailing worms by scanning email upon delivery mitigates the risk of infection via email.
