This 2 day course uses lectures and hands-on lab exercises to give participants real-time experience in setting up and configuring the BIG-IP® Advanced Firewall Manager system.

Students are introduced to the AFM user interface, stepping through various options that demonstrate how AFM is configured to build a network firewall and to detect and protect against DoS (Denial of Service) attacks.

Reporting and log facilities are also explained and used in the course labs. Further Firewall functionality and additional DoS facilities for DNS and SIP traffic are discussed.

Topics Covered

• Configuration and management of the BIGIP AFM system
• AFM Network Firewall concepts
• Network firewall options and modes
• Network firewall rules, policies, address/port lists, rule lists and schedules

• Export AFM system reports to your external monitoring system directly or via scheduled mail

• Allow chosen traffic to bypass DoS checks using Whitelists

• Isolate potentially bad clients from good using the Sweep Flood feature

• Isolate and re-route potentially bad network traffic for further inspection using IP Intelligence Shun functionality

• Restrict and report on certain types of DNS requests using DNS Firewall

• Configure, mitigate, and report on DNS based DoS attacks with the DNS DoS facility

• Configure, mitigate, and report on SIP based DoS attacks with the SIP DoS facility

• Configure, block, and report on the misuse of system services and ports using the Port Misuse feature

• Build and configure Network Firewall rules using BIG-IP iRules

• Be able to monitor and do initial troubleshooting of various AFM functionality
