A system and method for content request monitoring and filtering for a plurality of managed devices in a managed network uses a smart PAC file that is uniquely associated with a particular user using a particular managed device and a DNS look up to perform both the logging/monitoring of the content request and the filtering without a hardware appliance or partial proxying.

Managed network content monitoring and filtering system and method

A system and method for web filtering, including: generating an institutional policy dashboard that enables an institution that issued a computing device to a minor user to select a set of institutional web access policies sanctioned by the institution; generating a parental policy dashboard that enables a parent of the minor user to select to a set of parental web access policies sanctioned by the parent; filtering web content accessed by the minor user via the computing device by enforcing the parental and the institutional web access policies; and reporting to the parent a set of web accesses undertaken by the minor user via the computing device.

Web filtering system and method

A method is provided in one example embodiment and includes exchanging a session descriptor associated with a network connection and an application on a host, correlating the session descriptor with a network policy, and applying the network policy to the network connection. In alternative embodiments, the session descriptor may be exchanged through an out-of-band communication channel or an in-band communication channel.

System and method for interlocking a host and a gateway

Web filtering with integrated parental management and reporting

A particular failed connection attempt initiated by a particular source asset in a network is identified and subsequent failed connection attempts initiated by the particular source asset in the network during a time period are tracked. A low frequency sequence of failed connection attempts involving the particular source asset is detected during the time period and the source asset is designated as a potential security risk based on the detected low frequency sequence of failed connection attempts.

Stealth network attack monitoring

A method is provided in one example embodiment that includes detecting repetitive connections from a source node to a destination node, calculating a score for the source node based on the connections, and taking a policy action if the score exceeds a threshold score. In more particular embodiments, the repetitive connections use a hypertext transfer protocol and may include connections to a small number of unique domains, connections to small number of unique resources associated with the destination node, and/or a large number of connections to a resource in a domain. Moreover, heuristics may be used to score the source node and identify behavior indicative of a threat, such as a bot or other malware.

System and method for detecting a malicious command and control channel

Source assets are monitored for activities, each activity associated with a corresponding activity weight indicating probability of the activity resulting from a security compromise. A source asset is determined to perform a particular activity indicative of a potential security compromise, such as a download of an executable of malicious reputation. A source asset tracking instance is instantiated to include data identifying the particular activity. The tracking instance is to be updated based on identification of subsequently monitored activities. A reputation value is determined for the activity weight of the particular activity based at least in part on the malicious reputation of the executable. An asset reputation is determined for the source asset from the corresponding activity weights of monitored activities involving the source asset and a security risk is determined when the asset reputation exceeds a threshold.

Local reputation to adjust sensitivity of behavioral detection system

A method is provided in one example embodiment that includes identifying a file format identifier associated with a beginning of a file, parsing the file based on the file format identifier until an end of the file is identified, and calculating a hash from the beginning of the file to the end of the file. The method may also include sending the hash to a reputation system and taking a policy action based on the hash's reputation received from the reputation system.

System and method for detecting a file embedded in an arbitrary location and determining the reputation of the file

A system, method, and computer program product are provided for flagging a network flow as at least potentially unwanted. In use, a network flow is identified as utilizing an unknown protocol. Further, the network flow is flagged as at least potentially unwanted.
