Create an endpoint security integration authentication policy
You can use Okta Expression Language (EL) to create or edit an Global Session Policy that allows Okta to evaluate the trust signals collected by your endpoint detection and response (EDR) solution.
Start this procedure
In the Admin Console, go to Security > Authentication Policies.
Select the authentication policy that you want to add a rule to.
Click Add rule page.
Type a Rule name to describe the rule.
Configure the appropriate IF conditions to specify when the rule is applied.
Configure the appropriate THEN conditions to specify how authentication is enforced.
Configure the re-authentication frequency, if needed.
Specify signals by using custom expressions
You can specify the EDR signals you want a policy to evaluate by entering a custom expression. The custom expression must use valid Expression Language (EL) syntax. For example, you can use an expression similar to the following to integrate CrowdStrike ZTA signals into your authentication policy:
device.provider.zta.overall <= 60
device.provider.zta.overall >= 60
Similarly, you can use a custom expression to integrate Windows Security Center signals in to your authentication policy. For example:
device.provider.wsc.fireWall == "GOOD"
device.provider.wsc.fireWall == "POOR"
You can then use the EDR signals to tailor your allow or deny access rules to meet your security needs. For information about the EDR signals available, see Available EDR signals for custom expressions.
Authenticator assurance level compliance
The THEN conditions in an rule define how a user's identity can be validated. When you configure these settings, you should consider the level of compliance required. For EDR integration, the recommended settings are:
|For this||Do this|
|THEN Access is||Select Allowed after successful authentication.|
|AND User must authenticate with||
|AND Possession factor restraints are||Select Device bound (excludes phone and email).|
|AND Access with Okta FastPass is granted||Select If the user approves a prompt in Okta Verify or provides biometrics (meets NIST AAL2 requirements) to require users to prove that they're physically present when using Okta FastPass to authenticate.|
|Password re-authentication frequency is||Select Every sign-in attempt.|
|Re-authentication frequency for all other factors is||Select Every sign-in attempt.|
