Assignment

Implementation of secure login for privileged accounts utilising YubiKey Smart Cards

Process and outcome

The use of YubiKey's, hardware-based security keys, has been a standard security requirement for the Nexia Edwards Marshall IT team for some time; YubiKeys ensures a high level of security for administrative accounts on services such as:

-Password Management Systems
-Cloud Storage
-GitHub
-Google Accounts

The implementation and deployment of a Windows Certificate Server and Smart Card based authentication system utilizing YubiKey’s ensures that administrative accounts on Privileged Access Workstations have an even higher degree of security as hardware Smart Cards are now required to log on to these systems, not just a password.

Security is all about minimizing the attack surface all while maintaining the CIA Triad (Confidentiality, Integrity and Availability). Hardware security devices such as YubiKey's help ensure there is a physically separate, public key cryptography-based hardware device that ensures the entire process of user identification and authentication requires multiple factions prior to authorization; increasing integrity without effecting the availability of the systems.

Assignment

Implementation of NIST Special Publication 800-63 related to increased Password Checks to maintain password security

Process and outcome

Implementation and deployment of a technical control that checks and ensures users passwords are not part of a previous data breach as per recommendations by NIST Special Publication 800-63 https://www.nist.gov/itl/tig/projects/special-publication-800-63 that recommends user-provided passwords are checked against existing data breaches.

This check utilizes a secure and audited 3rd party application that leverages the ‘Have I Been Pwned’ password list to ensure any new password setup on the network has not been part of a data breach; any password found in the list is rejected and the user must select a new password.

Ensuring users are not using previously breach passwords helps reduce the likely hood of Credential Stuffing effecting our internal users accounts.

Assignment

Implementation of Privileged Access Workstations for all privileged accounts to reduce attack surface area of internal network and exceed industry baselines

Process and outcome

Implementation and deployment of Microsoft’s best practices related to Privileged Access Workstations (PAW) to ensure a total separation of computers and accounts between administrative and end-user tasks.

Using a Privileged Access Workstation to access servers and applications reduces the attack surface of networks servers and applications by limiting which systems can communicate with them while reducing the security risks associated with elevation of privilege attacks.

Privileged Access Workstation are locked down to reduce their attack surface and allows for better network monitoring to help discover malicious activities as all administrative tasks can be tracked and audited.

A Privileged Access Workstation (PAW) should be used by all ITC system administrators who administer High Risk servers and applications such as Active Directory, Certificate Services and finance systems.
