Untangle Attack Blocker

Prevent Denial-of-Service attacks—and keep your network focused on legitimate uses—with our patent-pending Attack Blocker.

“Unfriendly” machines earn bad reputations and are limited, dropped and rejected. Attack Blocker can also quickly identify unauthorized use of network resources and stop those resources from being allocated to unauthorized users.

Key Features:

• Dynamically blocks flood attacks based on reputation based heurisitics
• Carefully allocates network resources to legitimate users if network is under attack
• Create exception list of users allowed to behave aggressively
• EventLogs and reports show limited, dropped, and rejected events

Attack Blocker Technical Specifications

Attack Blocker protects your network because it does the following:

• Sanitizes all packets that the Untangle Server receives, and eliminates all packet-based attacks- you do not need to
• configure any settings because this packet-cleaning is a built-in function
• Protects against lower-level networking attacks
• Protects against Denial Of Service (DOS) attacks

Under The Hood:

Attack Blocker uses Untangle's patent-pending, proprietary technology. Attack Blocker observes the behavior of computers that access your protected network, and quickly assigns the host a good or bad reputation. Attack Blocker deems a computer to be aggressive or bad if it performs attacks, SYN flooding, or port scanning. Aggressive computers quickly earn bad reputations, and Attack Blocker eventually limits, drops, or rejects these computers access to your network.

Using this technique, Attack Blocker can mitigate Denial Of Service and Distributed Denial Of Service attacks. Attack Blocker also deconstructs each packet that enters the Untangle Server and reconstructs a new, trusted packet using the same data, eliminating all packet-layer attacks.

What It Does:

Protects you network from attack

How It Does It:

Uses Untangle's patent-pending technology to profile computers interacting with your network to determine the risk of attack, and then limits, drops or rejects access from attackers

Controls:

You can create exception lists to designate specific hosts or networks as unlikely to attack
