How to Configure Two Factor Authentication(2FA/MFA) for Cisco Webex

---

Two-Factor Authentication (2FA) or Multi-factor Authentication is the process of the authentication in which you have to provide two factors to gain the access into a particular application. First Factor is the one that you know username and password and Second factor is what you might have as unique, like a phone (For OTP) or Fingerprint. This additional layer of security prevents the unauthorized person from accessing the resources even if they know your username and password. miniOrange provides 15+ authentication methods and solutions to secure your applications.

5. Adaptive Authentication with Cisco Webex

A. Restricting access to Cisco Webex with IP Blocking

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

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

• Login to Self Service Console >> Adaptive Authentication.
• Add a Policy Name for your Adaptive Authentication Policy.



• Select your Action for behaviour Change and Challenge Type for user from the Action for behaviour Change Section.





Action for behaviour Change Options :




Attribute	Description
Allow	Allow user to authenticate and use services if Adaptive authentication condition is true.
Challenge	Challenge users with one of the three methods mentioned below for verifying user authenticity.
Deny	Deny user authentications and access to services if Adaptive authentication condition is true.




Challenge Type Options :




Attribute	Description
User second Factor	The User needs to authenticate using the second factor he has opted or assigned for such as OTP over SMS PUSH Notification OTP over Email And 12 more methods.
KBA (Knowledge-based authentication)	The System will ask user for 2 of 3 questions he has configured in his Self Service Console. Only after right answer to both questions user is allowed to proceed further.
OTP over Alternate Email	User will receive a OTP on the alternate email he has configured threw Self Service Console. Once user provides the correct OTP he is allowed to proceed further.



• Now 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 +.

B. Adaptive Authentication with Limiting number of devices.

Using Adaptive Authentication you can also restrict the number of devices the end user can access the Services on. You can allow end users to access services on a fixed no. of devices. The end users will be able to access services provided by us on this fixed no. of devices.

You can configure Adaptive Authentication with Device Restriction in following way
