SS7 Attack Management System (cont.) Since SSPs represent the SS7 network perimeter, authentication modules are positioned at each SSP to certify all entries. The modules detect attempts at spoofing and identity subversion by comparing SS7 messages with signatures of spoofing attacks. SS7 packet sniffers, specially designed to read and interpret SS7 messages, are the primary information gatherers of the attack management system. These are positioned to passively monitor all signaling channels. SS7 firewalls are designed to actively filter SS7 messages. They are positioned between SSPs and STPs to control traffic at all switching points. The firewalls screen traffic for attack signatures that are maintained in a special database. A real time fraud analyzer is located at each SCP as they interfaces with databases supporting PTN services. The analyzers examine SCP queries (TCAP messages) for suspicious patterns. SCP access control modules work in conjunction with fraud analyzers. They are positioned in front of SCPs to regulate entrance. 40 www.scanit.net Copyright © 2007 All rights reserved
