Block-IT (HAC)

Block-IT (HAC) is a host access control module through which administrators can restrict the user’s access to IP-based network hosts using programs such as Internet Explorer and others. Block-IT (HAC) is rule-driven; it allows administrators to create access control rules and assign them to clients. Clients could be users, groups, OU’s, or physical devices.

Block-IT (HAC) operates at the network layer. It intercepts requests from applications to connect to particular IP addresses on a particular TCP ports. In response to a connection request, the Block-IT (HAC) filter makes a decision on whether to allow or deny a particular connection by parsing the in-memory access control rules table. In essence, Block-IT (HAC) is a per-session firewall.
