Page 1 Tech Brief — Centralized Self-service Password Reset Summary For companies of all sizes, the task of supporting users can prove to be taxing on the IT staff, especially the Help Desk and Administrators. Most studies show the cost of password resets can range from $25 to $75 per incident and make up around 30 percent or more of Help Desk calls. This provides ample reason and demand for password reset and recovery tools which empower the user. By allowing users to self-service their own account and password management needs, organizations can effectively offer 24/7 access and maintain productivity. Shopping for a tool such as this can be challenging, so the first step is to understand your requirements by documenting your user access scenarios. For example, how will roaming users change their password remotely or how will a forgotten password be recovered on a laptop with an encrypted hard drive. Along with these requirements determining your budget and current Help Desk costs without a solution in place will allow you to forecast your ROI and further narrow down the vendor selection. Another point to consider is the evolution of self-service password reset and whether the vendors you are evaluating are keeping pace. Many tools you’ll find are not compliant with most companies’ current security standards. The problem of forgotten passwords has been around since passwords were first used, but expanding access scenarios and advanced attacks are requiring more advanced solutions. For example, entry point solutions are now expected to go beyond simple password resets to accept multiple scenarios which may include disconnected users, auditing and leveraging devices such as mobile phones. Of course, true success of a self-service password management solution will be measured by the users’ satisfaction and an overall reduction in the frequency of their calls to the Help Desk for support. The Basics Self-service password reset is the process a user initiates to prove their identity with the end goal of resetting their password. Self-service password recovery is similar, but the end goal is obtaining the current password value without changing it. The user can be authenticated using various methods. Most tools use challenge question and answer as an acceptable means of authenticating the user. However, associated security threats including easily guessed answers or information readily available on their Facebook page raise valid concerns. A secure solution puts additional precautions in place. For example, not allowing the same answer for each question, requiring a minimum answer length, and requiring a larger subset of questions (e.g. 3 out of 6) to be answered. For increased security, two-factor authentication can be added to the password reset and/ or recovery to ensure only an authorized user is setting the password. PortalGuard Centralized Self-service Password Reset PortalGuard’s self-service password reset is flexible and offers a complete solution which has evolved with industry demands. By providing the exact same interface for both Windows Desktop and Web-based self-service, the user’s learning curve is minimized and overall user adoption is increased. © 2012, PistolStar, Inc. dba PortalGuard All rights reserved. Page 2 Tech Brief — Centralized Self-service Password Reset The available self-service actions that PortalGuard offers are password reset, password recovery, and account unlock. These actions can also be performed from mobile devices such as iPads and smartphones. PortalGuard integrates seamlessly with Microsoft Active Directory, Novell eDirectory, any LDAP-compliant directories and custom SQL user repositories. PortalGuard also supports users who are offline or disconnected from the network, allowing them to perform a password recovery. In this case, the password is divided into mathematically-represented “shares” with each share being AES-256 encrypted by a separate challenge answer. All shares are then bulk encrypted with AES-256 using a separate key and stored locally on the user’s machine. When the user attempts to recover their password, they will be asked to prove their identity by correctly answering a certain number of challenge questions. Once decrypted, the user is shown the password in clear text allowing them to continue working. For security purposes, if a disconnected user strikes out while attempting to authenticate, the encrypted recovery information is deleted from the local machine, so the user will be forced to reconnect to the network to perform the recovery. To authenticate the user during an online self-service action, PortalGuard leverages challenge questions and answers and/or two-factor authentication via a one-time password sent to a mobile phone or email address. Challenge answers are cryptographically hashed and stored on a central server to support roaming users and prevent the need to re-enroll on multiple machines. By providing auditing and reporting around user access, an Admin App for the mobile phone, and user verbal authentication through a Help Desk console, PortalGuard is a comprehensive self-service password reset solution.

The screenshots provided are showing the process being completed from a web browser. A user can also complete the process from the Windows desktop using the same steps and identical interface. Enrollment Once self-service password reset is made available, the user will be prompted to enroll their challenge questions and answers. PortalGuard provides flexibility around this process by allowing you to configure whether the enrollment will be forced or able to be postponed “x” number of times by the user. This increases the usability for users, giving them options around a process some may find obstructive. NOTE: If other authentication methods are enforced, such as two-factor authentication, then those enrollment actions will also be displayed, as configured by the admin. © 2012, PistolStar, Inc. dba PortalGuard All rights reserved. Page 4 Tech Brief — Centralized Self-service Password Reset Enrollment Process NOTE: The screenshots below illustrate the use of PortalGuard’s “sidecar” functionality. It allows rapid integration of PortalGuard’s self-service features into existing websites or user processes. Step 1: The user attempts to login to a company’s existing portal as usual. Step 2: In this case, the user has not yet enrolled their challenge information so PortalGuard automatically displays the enrollment screen in “sidecar” mode. This dialog shows that the administrator has configured the PortalGuard policy to allow the option of skipping enrollment temporarily. Doing so will close the PortalGuard dialog and continue the original login process. The user can enroll now by clicking “Continue”. © 2012, PistolStar, Inc. dba PortalGuard All rights reserved. Page 5 Tech Brief — Centralized Self-service Password Reset Step 3: The user is prompted to provide answers to the challenge questions. The number of both mandatory and optional questions the user is required to answer is configurable. PortalGuard also increases security by helping the user perform best practices when supplying answers, such as not repeating answers or avoiding using words which are included in the question text. Throughout the enrollment process the user is provided with helpful warning notices, such as the number of answers remaining, to ease the frustrations some may feel during this process. Step 4: The process is complete and the user is now enrolled. Clicking the link shown will close the PortalGuard dialog and continue the original login process. © 2012, PistolStar, Inc. dba PortalGuard All rights reserved. Page 6 Tech Brief — Centralized Self-service Password Reset Self-service Password Reset Process Step 1: The user attempts to login to a company’s existing portal but has forgotten their password. The user then clicks the “Forgot your password?” link. Step 2: The user selects from “Recovery Actions Available” which self-service action they would like to perform. The user selects the “Reset Forgotten Password” radio button and clicks “Continue”. NOTE: The dialog shows the most common actions, an account unlock and password reset, but password recovery is also available. © 2012, PistolStar, Inc. dba PortalGuard All rights reserved. Page 7 Tech Brief — Centralized Self-service Password Reset Step 3: The user is then prompted to provide their enrolled answers to the enrolled challenge questions. PortalGuard provides users with helpful warning messages throughout this process. Once the user has supplied the required number of answers they click “Continue”. Step 4: The user’s identity has been verified and they are able to set a new password. Added usability and security features such as the “Show Password” checkbox and virtual keyboard can be easily enabled or disabled. © 2012, PistolStar, Inc. dba PortalGuard All rights reserved.
