Testing your Okta visibility and detection with Dorothy and Elastic Security

When approached by stakeholders in their organization, few security teams can confidently demonstrate that logging and alerting capabilities are working as expected. Organizations have become more distributed and reliant on cloud offerings for use cases such as identity and access management, user productivity, and file storage. Meanwhile, adversaries have extended their operational capabilities in cloud environments. It is crucial that security teams are able to monitor these systems for abuse in order to protect their organization’s data from attack. Dorothy is a free and open tool to help security teams test their visibility, monitoring, and detection capabilities for Okta Single Sign-On (SSO) environments. We’ll demonstrate how Dorothy can be used to execute tests and how Elastic Security can be used to alert on relevant and suspicious behavior using our free and open detection rules. What is Okta SSO?For those who aren’t familiar, Okta SSO is a cloud-based identity management solution that allows users to authenticate to a variety of systems and applications within their organization using a single user account. Informing end users that they only have to remember one username and password instead of ten or more reduces the risk that they’ll develop poor password hygiene and enables system administrators to enforce stronger password policies. Further, multi-factor authentication (MFA) policies can be configured in Okta, which raises the barrier to entry for attackers. Many attackers will simply move on and look for an easier target when they discover that MFA is enforced in their target’s network or user account. While SSO solutions can provide a convenient user experience and reduce cybersecurity risk for an organization, these centralized systems offer a type of skeleton key to many systems and applications, and are often an attractive target for attackers. It’s critical that security teams understand what normal behavior looks like in their Okta environment so that they can identify suspicious activity more easily. Meet DorothyDorothy has 25+ modules to simulate actions an attacker may take while operating in an Okta environment and behavior that security teams should monitor for, detect, and alert on. All modules are mapped to the relevant MITRE ATT&CK® tactics, such as Persistence, Defense Evasion, Discovery, and Impact.

Figure 1 - Starting Dorothy and listing its modulesDorothy was created to help defenders test their security visibility and controls, and does not provide any modules to obtain initial access or escalate privileges in an Okta environment. To execute actions using Dorothy, a valid Okta API token is required that is linked to a user with one or more administrator roles assigned. A user-friendly shell interface with contextual help is provided for navigation between menus and modules, helping guide the user through simulated intruder scenarios. Other features include configuration profiles to manage connections to individual Okta environments and detailed logging with the option of indexing events into Elasticsearch to provide an audit trail of the actions that were executed using Dorothy. Executing actions in an Okta environment using DorothyIn this section, we demonstrate how to execute some of Dorothy’s modules in an Okta environment. Figure 2 below shows the typical workflow for an Elastic Security user. After this demonstration, you should be comfortable with heading over to Dorothy’s GitHub repository and following the “Getting Started” steps in the project’s wiki.
