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.

    Course Overview:

    A skills focus enables the student to better absorb the subject matter and perform successfully on the job.  This is not death by power point. The course is aligned with information assurance operators and executing hands-on labs to secure Windows systems. Lecture and labs start with quick review of Active Directory and group policy to enforce security mechanisms within the Windows architecture.  Students then gain network experience and use sniffing to help exemplify the benefit of learning wired and wireless security configurations.  PowerShell is made for SecOps/DevOps automation and students will learn to write PowerShell scripts to automate security operations and Desired State Configuration (DSC).  The course concludes with exercising real attack strategies to demonstrate the effectives of properly securing your host.
