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: Both instructors Mr. Askey and Mr. Hackney, were very good. the open learning environment was extremely productive and I felt we all learned far more that we ever would out of a structured rote memorization course.

User: natebonds

Instructor comments: Both Mr. Askey and Hackney were extremely knowledgeable. They were also extremely interested in helping each student learn. I was particularly impressed with the way they tailored the course to optimize our time since we weren't testing. I feel like I know much much more than I did when the class started.

Facilities comments: The facilities were fine. I would have preferred it be closer to Lackland.

P-325: Python Programming

Course Overview:

This is an introductory course into the Python scripting language.  This class uses a hands-on approach in teaching the Python language.  This course builds the prerequisite skills for TechNow's P-345: Python for Pentration Testers course.  Getting comfortable with Python is important to understanding how Python can be utilitized for offensive measures.

This course is hands-on with the instructor walking the students through many short examples to exemplify an objective.  Dexterity with the language comes through many small code examples to produce the desired result.  Students have fun acquiring points for all the code examples they get correct.  We must be having fun because TechNow is always amazed at how competitive students are in trying to acquire the most points!  

The instructor will focus on the level that each student is currently at, and ensure the student absorbs the subject matter.  Programming is not a daily tasking of administrators or offensive operators and TechNow understands that.  As an instructor led course TechNow is very successful in making Python accessible to those who do not live eat and breath programming.  If a student's ultimate goal is to attend a course like TechNow's P-345: Python for Pentration Testers course, then not being bogged down in the Python language is critical, and this course (P-325: Python Programming) meets that objective.

Recently we have introduced Raspberry Pi's and multiple sensors to the P-325: Python Programming course.  This enables the student to actually see productive results from their coding skills in the physical world!  Some examples that students create programs for are: Motion detectors, distance, temperature, cameras and keypads.

Attendees to P-325: Python Programming will receive TechNow approved course materials and expert instruction.
