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: m_jurrens

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-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.
