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.

TN-813: Certified in Governance, Risk and Compliance (CGRC)

Course Overview:

TN-813: Certified in Governance, Risk, and Compliance (CGRC) course is for the (ISC)²® Certified in Governance, Risk, and Compliance (CGRC) credential previously known as Certified Authorization Professional (CAP). This course walks the student through the Risk Management Framework following practices the NIST pubs. CGRC is an objective measure of the knowledge, skills and abilities required for personnel involved in the process of certifying and accrediting security of information systems. Specifically, this credential applies to those responsible for formalizing processes used to assess risk and establish security requirements. Their decisions will ensure that information systems possess security commensurate with the level of exposure to potential risk, as well as damage to assets or individuals.The CGRC credential is appropriate for civilian, state and local governments in the U.S., as well as commercial markets. CGRC certification applies to job functions such as authorization officials, system owners, information owners, information system security officers, and certifiers. CGRC is crucial to the Management staff.

This course is the “why” of the entire security field. It provides a logical way of allocating resources where there is greatest risk and why we make the decisions we make in the field of security. It is TechNow’s view that of all the security courses we have seen, this course genuinely puts the “big picture” of security in front of the students. Students actually come to an understanding of truly what is critical to security of an enterprise versus a bunch of nuts and bolts of security.

TechNow’s CGRC course covers all of the (ISC)²® CGRC 7 Knowledge domains:

Security and Privacy Governance, Risk Management, and Compliance Program
Scope of the System
Selection and Approval of Framework, Security, and Privacy Controls
Implementation of Security and Privacy Controls
Assessment/ Audit of Security and Privacy Controls
System Compliance
Compliance Maintenance

RMF Related Steps
