IP Restriction for Slack

---

How can IP Restriction restrict access to Slack?

miniOrange allows you to use IP Restriction policy to provide or deny access to the users based on trusted IP Addresses.

• For the IP Restriction to work, the Admin must create a policy specifying permitted IP addresses which allows the access to the application.
• miniOrange supports IP addresses range in three formats i.e. IPv4, IPv4 CIDR and IPv6 CIDR.
• To block the access, Admin must specify an action which needs to be performed when a user tries to login from a non trusted IP address (Such as Deny or Challenge the user with 2FA).
• Once the restriction policy is configured, it can be applied to any application’s login policy to enable IP restriction for that application

3. Configure IP Restriction: Restricting access with IP Blocking

You can allow a IP Address in certain range for SSO or you can deny it based on your requirements and you can also challenge the user to verify his authenticity. Adaptive authentication manages the user authentication based on different factors such as Device ID, Location, Time of Access, IP Address and many more, thus improving the security and functionality of Single Sign-On.

You can configure Adaptive Authentication with IP Blocking in following way:


• Go to Adaptive Authentication from the left navigation bar.
• Click on Add Policy tab.
• Add a Policy Name for your Adaptive Authentication Policy.



• Enable Enable IP Restriction option from the IP RESTRICTION CONFIGURATION section to configure custom IP range.



• Select the Action you want to perform if the IP address is out of the range. i.e. Allow, Challenge & Deny.
• Specify the IP Address range for which you want above setting to reflect. You can add more than one IP Address ranges by clicking on following button +.
• We support IP addresses range in three formats i.e. IPv4, IPv4 CIDR and IPv6 CIDR. You can choose whichever is suitable for you from the dropdown menu.
• Now select your Action for behavior Change and Challenge Type for user from the Action for behavior Change Section.





Action for behavior Change Options :




Attribute	Description
Allow	Allow user to authenticate and use services if Adaptive authentication condition is true.
