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.

Instructor comments: While I could tell the instructor was very knowledgeable, his instructions were not very clear. He could've done a better job preparing for the class.

Facilities comments: Room was fine. The location of the room could have been better as the dings from the elevator were a bit distractive.

User: TracyPaul

Instructor comments: Very knowledgeable. Diagnosed our programming problems in short order. Could go into the details of 'why', versus only the 'how'.

Facilities comments: Outstanding. The hotel staff did a great job supporting our class.
