The secure infrastructure configuration should be the most important line of defense in every organization. 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! This is a deep dive course on security operations: vulnerability management, anomalies detection, discovery of industry attacks and threats, understanding how compromised system or solution looks like, defining the indicators of the attack, incident handling also daily servicing on SIEM platform. We will also walk through the advanced access rights, password mechanisms, windows internals, PowerShell usage for security purposes, gaining unauthorized access, advanced DNS configuration and common configuration mistakes, forensics techniques, 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. The training focuses on detecting, responding, and resolving computer security incidents.
