Intensive Networking (IN) – 1 day

This course is designed specifically for candidates who do not have the full pre-requisites to embark on the CSA or CTM course or for those wishing to refresh their knowledge prior to attending.

You will cover a range of networking topics including fundamental concepts, such as OSI model, TCP/IP stack, IP routing, manipulating IP addresses, subnetting and creating custom subnet masks. The tools and techniques taught will cover the Windows and Linux operating systems to give you insight into using command line tools to interrogate, manipulate and test network and Internet connections.

The course is a mix of theoretical networking content and hands on sessions.

The course concludes with a short practical assessment of skills.

Who is the course designed for?

  • Professionals in public or private enterprise who are involved or interested in vulnerability / penetration testing and IT security, but require some grounding in networking before progressing.
  • Professionals wishing to progress further by taking the CSA or CTM courses and exams and ultimately to become CHECK Team Members (CTM).



Successful candidates will receive a BlackBerry Verified ‘Intensive Networking’ Certificate of Attainment

Per course pricing

This course is available “per course” meaning a course is prepared and delivered for you and your needs. There is no minimum number of candidates. The course cost does not change based on the number of candidates so if an individual requires a course with only one candidate then that’s fine, however the course fee remains the same for 1 candidate as it does for 6. The dates of the courses are flexible and are decided by you as long as we have a member of training staff available.
