  • Security Active Directory Access LDAP
  • Validating Security Changes with OpenVAS

Lab time: It will take approximately 1 hour and 30 minutes to complete this lab.

Exam Objectives

The following exam objectives are covered in this lab:

  • Design and validate assessment and test strategies
  • Conduct security control testing
  • Collect security process data (e.g., management and operational controls)
  • Analyze and report test outputs (e.g., automated, manual)
  • Conduct or facilitate internal and third party audits
  • Implement and support patch and vulnerability management

Exercise 1 - Connecting to Kali

Kali is a multifaceted Linux operating system which is mainly focused towards security and penetration testing. It combines a wide range of tools, from port scanners both active and passive to forensic tools which can be used to pull deleted data off hard drives.

Exercise 2 - OpenVAS Scanning

OpenVAS stands for Open Vulnerability Assessment System and is a fork from an older version of Nessus, formally known as GNessUs. It’s a free tool to use and can be quite comprehensive in its scanning techniques as well assisting in finding vulnerabilities. It can be used in conjunction with other Kali tools to help pen test environments more efficiently.

Exercise 3 - Securing Active Directory Access LDAP

Active Directory holds a great of critical information about a business or organisation regarding how its structured, who the participating members are, the groups and positions of those members, how the domain is defined and which computer groups are assigned. It has overall control across the network and is very powerful at enforcing policy rights. Throughout the years as Windows and devices have changed it has grown very large and complicated, it provides backwards compatibility for older services as well, however back in the days of Windows 2000 security wasn’t well understood and mainly holes in older system were exploitable.

Exercise 4 - Validating Security Changes with OpenVAS

Once changes have been made to any system, it is vital that a recheck of the system is made in order to confirm that updates, patches and security configuration have taken place and are functioning correctly as expected.
