Firewall

IASP utilizes best-in-class hardware and industry standard practices to define its perimeter security defenses. IASP provides multiple redundant Cisco Enterprise Secure ASA and PIX firewalls to define its perimeters and utilizes multiple true DMZ's to define security perimeters and extranets as required by clients. IASP deploys the ASA and PIX Firewalls in a four-interface configuration with Cisco router access control lists (ACLs) for packet filtering, providing a strong barrier to unauthorized users. The ASA and PIX Firewalls' protection design is based on Adaptive Security Algorithm (ASA), which tracks the source and destination address, TCP sequence numbers, port numbers, and additional TCP flags for each packet. All inbound and outbound packets are compared against these entries. Access is permitted through the ASA and PIX Firewalls only if an appropriate connection exists to validate passage. IASP also utilizes a double natting standard and virtual IPs for conduits and access lists to define traffic flow through its firewalls. This standard for security is maintained at all times and at all costs to ensure clients the safest platform available for their data.
