The secure infrastructure configuration should be the most important line of defence in every organisation. Unfortunately, people, the most valuable resource, are not always aware of the level of security in their companies, possible points of entry, how operating systems are attacked, and how to protect the infrastructure from successful attacks which are sometimes caused by configuration mistakes. Understanding internal OS protection mechanisms and services/roles completely provides a huge impact on the whole infrastructure security level. Unfortunately, the problem is… rarely anyone has this impact! Advanced access rights, password mechanisms, windows internals, PowerShell usage for security purposes, gaining unauthorised access, advanced DNS configuration and common configuration mistakes, Active Directory security, IIS Security, debugging, advanced monitoring and troubleshooting and much more! Topics covered during this training will help you to walk in hackers' shoes and evaluate your infrastructure from their point of view.
