Initial Access on Pen Tests
 
Tim Medin will present content and lab demos from SEC560: Enterprise Penetration Testing on gaining initial access on penetration tests. The initial access mechanisms described are used by Tim and his team to successfully compromise the first system(s) on pen tests, which then leads to post-exploitation and a deeper analysis of the target network. Join him for this fun and interesting look at common methods used to compromise target systems as part of a successful enterprise penetration test.
