The document presents an overview of PortalGuard's contextual authentication platform, which balances usability and security through a multi-factor authentication approach. It highlights various authentication methods and their adaptability to different access scenarios, emphasizing a proactive approach to reducing threats while enhancing user experience. Technical requirements for installation and configuration details are also provided, ensuring compatibility with various systems.

1. Understanding PortalGuard’s
Contextual Authentication:
A Multi-factor Approach
Highlighting the Multi-factor Authentication Layer of the
PortalGuard Platform

2. By the end of this tutorial you will be able to…
• Define PortalGuard
• Understand the barriers to increasing security
• Discover PortalGuard’s Contextual Authentication (CBA)
• See the Step-by-step Authentication Process
• Know the Technical Requirements

3. The PortalGuard software is a Contextual Authentication platform
which is focused on enhancing usability, while maintaining a
balance between security, auditing and compliance for your web,
desktop and mobile applications.
Usability Security
• Single Sign-on • Knowledge-based
• Password Management • Two-factor Authentication
• Password Synchronization • Contextual Authentication
• Self-service Password Reset • Real-time Reports/Alerts

4. Before going into the details…
• Configurable by user, group or application
• Stop making assumptions about who is accessing your applications
• Adjust the authentication method dynamically with every access request
• Gain insight into user access scenarios
• Cost effective and competitively priced
• Tailored Authentication for an exact fit

5. Remote Access
Security vs. Usability

6. Two-factor Authentication for All Users = No Flexibility
Although desirable for security the barriers are overwhelming…
• Not able to adapt to different access scenarios
• Requires dedicated IT resources and hardware
• High total cost of ownership
• Increased Help Desk calls due to user frustrations

7. Two-factor Authentication for All Users = No Flexibility
Is there a midpoint between passwords and
two-factor authentication?

8. Contextual Authentication is the Midpoint.
Apply the appropriate authentication level…
• Location
Password-based
• Time
• Device
• Network Multi-factor
• Application
Password-based

9. • Cost effective
• Flexible
• Five authentication methods:
Password-based Single Sign-on
Contextual Authentication (CBA)
Two-factor Authentication
Knowledge-based
• Two-factor authentication options – soft tokens
• SAML single sign-on
• Real-time activity alerts
• Notifications & Reporting

11. • Increased security – without impacting the user experience
• Increase usability for authorized users while creating barriers for
unauthorized users
• Flexibility - configurable to the user, group or application levels
• Lower total cost of ownership than hard token two-factor
authentication alternatives
• Reduce threats using a proactive approach
• Gather Insight – analyze contextual data reports

12. Authentication Method:
• Single sign-on: username and password (single password for multiple
systems)
• Password-based: username and password
• Knowledge-based: username, password and challenge question
• One-time Password (OTP): username and OTP
• Multi-factor: username, password and OTP or contextual data

13. Credibility Score:
A numeric value that is used to determine the appropriate
authentication method based on a set of ranges.
Credibility Policy:
A configurable policy based on
categories and identifiers to
which you can assign a score.

14. Weight:
An optional percentage for each category that adjusts the
category’s impact on the credibility score versus other categories.
Application
Realms:
Identifies an
application and
assigns a weight to
that application
that adjusts the
overall credibility
score.

15. HOW IT WORKS

16. Analysis Mode:
Recommended for a 60-90 day period to establish a baseline for the
environment.

17. Client-side Browser Add-on:
Optional to collect users contextual data and can be installed silently
using a standard MSI.

18. Step 2:
The user begins the login process by entering their username and
clicking “Continue”.
Step 3:
The PortalGuard server
identifies the user’s
credibility policy and
computes the following:
• Gross score for each category
• Any category weight impact to the
score
• Net score from the policy and weights
• Modification due to sensitivity of
requested application

19. Step 4:
Contextual data is sent from the client-side
browser add-on to the PortalGuard server.
The PortalGuard server looks up the
appropriate authentication method using
the final credibility score and previously set
ranges.
PortalGuard enforced the appropriate authentication method for the
user’s current access attempt. The user provides the required
credentials to successfully complete their access request and login.

20. Configurable through the PortalGuard Configuration Utility:
• Enable or Disable CBA
• Assign users or groups to individual credibility policies
• Credibility Policy:
• Client Type
• Use Category Weighting
• Enforce Application Realms
• Display Scoring UI
• Categories
• Weight
• Identifiers
• Credibility Score

21. Configurable through the PortalGuard Configuration Utility:
• Default Ranges:
• Start and End Scores
• Authentication Types
• Alert On or Off

22. Configurable through the PortalGuard Configuration Utility:
• Application Realms
