Privileged Access Management Geoff Gottlieb ISSA Chapter Meeting 6/6/19

What is privileged access? Privileged accounts provide elevated, often unrestricted access to an organization's underlying information systems and technology, making them rich targets for both external and internal malicious actors. Often referred to as the "keys to the kingdom," these accounts have been used in successful attacks to gain access to corporate resources and critical systems (e.g., "crown jewels"), resulting in data breaches. NCCOE Practice Guide on Privileged Account Management (https://www.nccoe.nist.gov/projects/use-cases/privileged-account- management)

Keys to the Kingdom Domain administrators Unix/Linux root level administrators Firewall administrators Database administrators Server administrators Virtualization environment administrators

But what about…. Business users who run data queries Developers who have broad access to data Service accounts that have broad access to data and systems Application accounts that run web facing and other applications that have broad access to data and systems

How guarded is the kingdom? Do you allow remote administration from a user’s workstation? Do you allow database queries from a user’s workstation? Do you block anything between your user’s workstation and your infrastructure environment? Do all your servers have the same built-in administrator username/password?

This is actually easier than you think.. Bloodhound (https://posts.specterops.io/tagged/bloodhound)

Where do you start? Microsoft has a great white paper on where to start. They have skin in the game, but this guidance can be followed without purchasing anything https://docs.microsoft.com/en-us/windows- server/identity/securing-privileged-access/securing-privileged- access CyberArk is one of the leaders in the Privileged Access space. They also have a free discovery tool https://www.cyberark.com/privileged-access-security/ BeyondTrust & Thycotic – Other software players in the space

Where did we start? Multifactor authentication to the data warehouse Built-in server administrator accounts We used CyberArk EPV Microsoft LAPS is also available for free https://www.microsoft.com/en-us/download/details.aspx?id=46899 Domain Administrators – Password Vault Isolated privileged account Frequent rotation (Typically 12 hours after use) Other accounts with broad reach into the environment CyberArk Discovery & Assessment

Where are we going? Workstation environment separate from data center All system administration and distributed development performed via privileged accounts Admin sessions isolated so privileged passwords are not stored on the workstation (Privileged Session Manager) More multifactor authentication for more users Application and service account password rotation Detection for Pass the Hash and Pass the Ticket
