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.

Palo Alto Networks Firewall Training Course Lab

Working with the TechNow lab for the PA-215: Palo Alto Networks Firewall Essentials FastTrack course has been nothing less than a techie's idea of fun.  When students come in we are immediatly configuring the Cisco 3750 switches for access ports, VLANS, and trunks.  We then cable the switch to the Palo Alto Networks Firewall.  Each student gets their own Palo Alto Firewall Pod of hardware and software.  What we find as fun is the VLAN environment, with an array of virtual machines hosted on an ESXi server that can really exercise the abilities of the Palo Alto Firewall.  The DMZ VLAN hosts virtual machines that support enterprise services and also potentialy vulnerable web services.  The Trust VLAN has Windows and Linux clients.  The UnTrust VLAN has Web services and a VM of Kali. The hardware Firewall is additionally connected to a Management VLAN.  All those VLANs are trunked into an ESXi server where the student also has a VM-Series Palo Alto Networks Firewall for High Availability.  

After configuring all the trunking, VLANs, and network interfaces we learn about the firewall and configure it for the lab environment.  Using Metasploitable and Kali/Metasploit nefarious penetration attempts are executed.  Using packet captures, custom APP-ID's  and custom signatures are generated.  Custom logging and reporting are created to similate and enterprise and assist the desired Incident Response.  It is always fun in a training environment to learn all about the controls available in a product, even though specific controls may not be used in the operational environment.  In the end we have a good understanding of the Palo Alto Networks Firewall.

TN-963: 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-963: Windows Security Automation with PowerShell will receive TechNow approved course materials and expert instruction.
