Intrusion Detection & Prevention

• Send to a colleague

AT&T Managed Intrusion Detection Service protects your networking infrastructure by detecting and responding to unauthorized attempts to access your network. The hardware/software application is installed on your premises and connected to the AT&T Security Operations Center, where AT&T Service Technicians provide round-the-clock surveillance. The service monitors network traffic for potential misuse from internal and external sources, by capturing IP packets and performing real-time "signature" analysis, comparing the packets to a continually-updated database of over 1000 existing attack signatures. When a pattern of misuse is detected, the system quickly and automatically responds according to your predefined policies to send an alert and take immediate action.

AT&T, the recognized leader in network security, provides maintenance procedures, installation and day-to-day management. In addition, the full-managed service includes maintenance of hardware and software components and installation of required upgrades.

The service monitors your network via an unaddressed monitor port on a switch at your premises. Cisco Secure Intrusion Detection Sensors located at your site use a signature-based approach to perform real-time intrusion detection at the network level. This involves the capture and real-time analysis of IP packet "signatures" by performing both context and content monitoring. Context monitoring entails the examination of the IP packet header data. Content monitoring evaluates the assembly and examines the data content of a single or series of IP packets.
