We have conducted third-party accessibility assessments over the course of product development for many years, and most recently a comprehensive audit against the WCAG 2.1 / VPAT 2.3 standards for all major product modules was completed in September 2019. Tanium can make available any VPAT reports on a module-by-module basis as part of a larger solution planning process for any customer or prospect. As new products and features are continuously delivered, Tanium will conduct testing to identify potential gaps in compliance with accessibility guidelines. Tanium is committed to making best efforts to address any gaps quickly, as is feasible, given the severity of the issue and scope of the changes. These objectives are factored into the ongoing delivery schedule of features and releases with our existing resources. Tanium welcomes customer input on making solutions accessible based on your Tanium modules and assistive technology requirements. Accessibility requirements are important to the Tanium customer community and we are committed to prioritizing these compliance efforts as part of our overall product roadmap.

  • How to Restart Premisys Services
    PremiSys Services Troubleshooting Introduction There are two services which comprise the PremiSys application server components. These services are: • IDenticard Windows Service • IDenticard Scheduling Service Under normal conditions, both of these services are configured to start automatically when the server starts. Both are also dependent on connection to the PremiSys databases which are hosted by a Microsoft SQL Server. The instance of SQL Server may or may not reside on the same server as the PremiSys application server, depending on the way the system has been designed. IDenticard Windows Service The IDenticard Windows Service is the primary server component of the PremiSys software. It handles the server side code for client logins, licensing, panel communications, transaction processing, etc. When this service is stopped, any running instance of the PremiSys client will receive a message box that indicates “The connection to the {server name} license server has been lost”. When the user acknowledges this message box, the client application will close. If a user attempts to restart the client application while the IDenticard Windows Service is stopped on the Application Server, they will receive a message box which indicates “AddIn Architecture Failed to start – Services unavailable…”. IDenticard Scheduling Service The IDenticard Scheduling Service runs various tasks within a PremiSys system. This includes, but is not limited to user- scheduled tasks for things like backups, transaction archives, reports and door schedules. When this service is stopped, any scheduled tasks will not run on their scheduled execution time. Starting Services Step-By-Step 1. Click on the “Windows Start Menu” Button on the lower-right corner of the Windows Desktop 2.

  • Event Logs What Are Event Logs?
    Event Logs What are event logs? Windows keeps track of almost everything that happens in the operating system Microsoft defines an event as "any significant occurrence in the system or in a program that requires users to be notified or an entry added to a log." Examples of events are log ons, log offs, connections to wireless access points, improper shut downs of the computer, installations of programs, etc Windows Event Logs ● What is actually recorded in the event log is dependent on the applications involved and the system settings ● Security event logging is disabled by default on most freshly installed windows sysstems. ● If they exists, event logs cad be incredibly useful, they would provided both local and network context that is difficult to replicate with other artifacts. Event Log Analysis ● What Happened?: Event ID ->Event Category->Description ● Date/Time?: Time Stamp ● Users involved?: User Account->Description ● Systems Involved?:Hostname->IP Address ● Resources Accessed?: Files->Folders->Printers->Services Event Analysis Cont. ● What Happened? ○ Even logs are designed to provide very specific information about activities that occurred on the system. ○ Items like Event IDs and Event Categories help to find relevant events ○ Event Description can provide more information of its nature ● Date/Time? ○ Timestamps are key in event logs. ○ The provide a temporal context of the events ○ Can also help narrow an investigators focus. Event Log Analysis Cont. ● Users Involved? ○ Everything done within Windows is done using the context of an account ○ We can: ■ Identify references to specific users ■ Information about the Windows OS activities via special accounts like System and NetworkService.
