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.

Instructor comments: great presentation

Facilities comments: too cold

User: fillyok

Instructor comments: He has an excellent way of explaining things on the level that anyone can understand easily. I wasn't looking forward to this class at all but I'm really glad I attended now. I have a much clearer understanding of networking fundamentals that I never would've received via CBTs. I'd heard really good things about Tim Burkard's teaching skills and now I know they're true. I wouldn't mind taking other classes that he teaches,

Facilities comments: The facilities are really nice and there weren't any problems as far as I could tell. The hotel staff is very nice.
