N-595: VoIP Security Analysis and Design

Course Overview:

As VoIP (Voice-over IP) is integrated into the operations of many missions, it is imperative to understand its security ramifications. In the N-595: VoIP Security Analysis and Design class the objectives are designed for those who are chartered with the responsibility of securing networks and application environments that incorporate VoIP. Topics include how VoIP works, its interactions with the network, its vulnerabilities and mitigations. Focus is on leading open source and proprietary technologies utilizing Asterisk and Cisco and the protocols SIP, H.323, RTP, MGCP, and Skinny. Other protocols such as Nortel's UNIStim will be addressed. As for Cisco, security pieces in the VoIP CallManager servers, Catalyst switches, IOS-based routers, and ASA firewalls, amounts to several different platforms, each with its own management interface and lockdown procedures. Various open source tools including those in BackTrack are used for VoIP attacks. A task list of actions for securing enterprise VoIP is carried out in hands-on labs, performed on Cisco phones, routers, switches, and ASA firewalls.

Attendees to N-595: VoIP Security Analysis and Design will receive TechNow approved course materials and expert instruction.

PA-213: Palo Alto Networks Firewall Install, Configure, and Manage (EDU-201)

Course Overview: PA-213: Palo Alto Networks Firewall Install, Configure, and Manage (EDU-201) Training Class is a three-day course that teaches students to configure and manage the entire line of Palo Alto Networks next-generation firewalls. This course prepares the student for the Palo Alto Networks Accredited Configuration Engineer (ACE) and progress to the Palo Alto Networks Certified Network Security Engineer (PCNSE). Through hands-on training, students learn high end skills of how to integrate Palo Alto next-generation firewalls into their network infrastructure. This is not a virtualized theoretical course. This is hands-on, real world instruction, directly relevant to the DoD and Commercial implementations of Palo Alto Networks next-generation firewalls.

Each student is issued a physical Palo Alto firewall and a Cisco layer 3 switch at their desk. Real hardware per student for real experience and real skill development. TechNow provides a very comprehensive client infrastructure that includes Windows, Linux, and multiple packet sniffer agents.

This course sets up the foundation for the two day course PA-212: Palo Alto Networks Firewall Configure Extended Features. The instructor for this course has been a lead in Unix kernel development to implement firewall and intrusion detection technologies. Additionally, the instructor has taught several security appliance products and carries several SANS, ISC2, ISACA, Cisco, Unix, and Windows certifications.

Attendees to the PA-213: Palo Alto Networks Firewall Install, Configure, and Manage (EDU-201) Training Course will receive TechNow approved course materials and expert instruction.
