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.

CT-405: PenTest+

 

 

 

 

 

 

Course Overview:

PenTest+ is an intermediate-level certification for cybersecurity professionals who are tasked with penetration testing to identify, exploit, report, and manage vulnerabilities on a network. PenTest+ is at the same certification level as CT-395: CySA+. Depending on your course of study, PenTest+ and CySA+ can be taken in any order, but typically follow the skills learned in CT-325: Security+. PenTest+ focuses on offense through penetration testing and vulnerability assessment while CySA+ focuses on defense through incident detection and response. The most qualified cybersecurity professionals have both offensive and defensive skills. Attend Tech Now training for hands-on, instructor led course to prepare you for the CompTIA PT0-002 exam. This exam is hands-on, performance-based questions and multiple choice, to ensure each candidate possesses the skills, knowledge, and ability to perform tasks on systems.
