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.

User: sjsmith2262

Instructor comments: without question, Dave Askey knows his material!!! great instructor that gave a personalized approach.

Facilities comments: class was taught in a hotel reception area, very nice, quiet and convenient for all people

User: synistry

Instructor comments: Dave was great! (as always). Wealth of knowledge and a master at customizing course content to match the education level of his students. The class kept entirely in pace with where we were at as a group overall on a day to day basis.

Facilities comments: Facilities were overall really nice. The only complaint is that the hotel / conference center had us move rooms on one occasion, and kicked us out early on two others. I would assume this is due to the last minute location change, so I don't think there is anything anyone could have done better in the situation.

VM-345: VMware Infrastructure Security: VMware Install, Configure, and Manage with Security Objectives

Course Overview:

This course explores the VMware Infrastructure and related security, which consists of VMware ESX Server & VMware Virtual Center Server. We will look at both the design environments and operational processes of the VMware Infrastructure including security. This course provides IT architects with the insight needed to tackle tough issues in server virtualization such as virtual machine technologies, storage infrastructure, and designing clustered environments with security practices included. Extensive hands-on labs provide for a rich student experience.

Hypervisors and their supporting environment require attention to security due to the aggregated risk of hosting multiple virtual servers. This course explores the security of virtualized environments. Student configure ESXi by learning to manage the security and risk between ESXi, virtual servers and security integration of ESXi to the physical network infrastructure including appropriate segregation from other sensitive networks and management networks. How to configure virtual networks when some hosts are dual or multi homed, but internally segregate between the two or more connected networks with different security levels. Appropriate integration of zero-clients and thin clients. Configuration of defensive measures on hosts, servers, hypervisors within the virtual environment and practices for those guarding it externally. Integration of Active Directory and other AAA/CIA related services relative to a virtualized environment.

Students are also walked through DoD ESXi Security Technical Implementation Guide (STIG). Introduction to the impact of Intel Trusted Execution Technology integrated with ESXi to create a trusted platform for virtual machines. Additionally the instructor walks the students through NIST Special Publication 800-125A: Security Recommendations for Hypervisor Deployment on Servers, and NIST Special Publication 800-125B: Secure Virtual Network Configuration for Virtual Machine (VM) Protection.
