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.

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.

Attendees to “VM-345: VMware Infrastructure Security: VMware Install, Configure, and Manage with Security Objectives” will receive TechNow approved course materials and expert instruction.

TN-965 Windows Security Automation with Powershell

Course Overview:

PowerShell is made for Security Operations (SecOps) automation on Windows. SecOps requires automation in order to scale out security changes and monitoring beyond a handful of hosts. For example, when a vulnerability must be remediated but there is no patch for it yet, automation is needed to quickly and consistently enact the changes necessary. PowerShell “remoting” is encrypted remote command execution of PowerShell scripts in a way that can scale to thousands of endpoints and servers.

Imagine being able to hunt for indicators of compromise across thousands of machines with just a few lines of PowerShell code. Or imagine having the local Administrator account password reset every night on thousands of endpoints in a secure way, and being able to retrieve that password securely too.

We will show you to do these tasks and more. Transcription logging for forensics, strong encryption code signing, application whitelisting of scripts, IPSec port control, and Just Enough Admin (JEA).

As more and more of our systems are moved up to the cloud, PowerShell will become even more important. Amazon Web Services, Microsoft Azure, Office 365, Hyper-V and VMware already support PowerShell administration for many tasks.

Attendees to TN-965: Windows Security Automation with PowerShell will receive TechNow approved course materials and expert instruction.
