Enabling Client / Server Communication Encryption in Access It! Universal.NET V5
print icon

This article pertains to a version of software no longer supported by RS2 Technologies.

 

Overview

The Access It! Universal.NET Username and Password are stored within the AIUniversal database. The Username is stored as clear text and the Password is encrypted.

DCOM is used for all communications between the Client and the Server when the Client machine is requesting database Look ups, Adds, Updates, or Deletes in Access It! Universal.NET v5 and prior. By default DCOM does not encrypt the information being sent through it therefore Access It! Universal.NET does not encrypt the data.

Enabling DCOM Encryption

To enable DCOM encryption, follow these steps on all of the Client machines.

  1. Run DCOMCNFG (Start | Run | DCOMCNFG)
  2. Navigate to DCOM Config (Component Services | Computers | My Computer | DCOM Config)
  3. Right click on AIUniWks and select Properties
  4. Set Authentication Level: from Default to Packet Privacy
  5. Click OK
  6. Launch Access It! Universal

Summary

After completing the top 6 steps all database reads and writes to and from the Client and Server machines will be encrypted.

Overall packet sizes will increase slightly as encrypted packets require more overhead in general.

Client machines are set up to receive events by default. These events include Alarms, transactions within the Event Viewer, and information that comes back as a response to an SCP status request. Events are anything other than database Look ups, Adds, Updates, or Deletes.

Events are transmitted to the Clients via a TCP socket connection from the Client to the Server on port 3030 as clear text. These events are not and cannot be encrypted.
