Glossary F filtering logs: Viewing selected information from logged information. For example, a filter can be set up so that you can view only blocked traffic, critical information, or logged events occurring during the past day. See also logs. firewall: Hardware, software, or a combination of both that is used to prevent unauthorized Internet users from accessing a private network. All information entering or leaving a network must pass through a firewall, which examines the information packets and blocks those that do not meet security criteria. The Sygate Security Agent Allows or Blocks whether incoming traffic is allowed to access an organization's network or resources. By using firewall rules, an Agent can systematically allow and block incoming traffic from specific IP addresses and ports. See also firewall rule, Sygate Security Agent. firewall rule: A stipulation that helps determine whether or not a computer can gain access to a network. For example, a firewall rule may state "Port 80 is allowed." G groups: All users and computers on an enterprise network are organized into groups with similar security needs and settings. Computer and Users Groups are created and maintained by a system administrator on the Sygate Management Server. A group cannot be edited unless it is locked or checked-out first making it so only one administrator can make changes to it at any time. See also Computer Group, Users Group, Global Group. GUID: Global Unique Identifier. See unique ID. H hijack: A type of attack where an intruder takes control of an existing communication session between a server and a legitimate user who has connected and authenticated with the server. The intruder can monitor the session passively recording the transfer of sensitive information such as passwords and code. Another type of hijacking involves an active attack done by forcing the user offline (with a Denial of Service attack) and taking over the session. The intruder begins acting like the user, executing commands, and sending information to the server. HP Sygate Security Agent: See Sygate Security Agent.
