  3. HAMILTONVENUSSecurity Settings • Checksum Verification • Each method file contains a check sum. • Checksum is a count of the number of bits in a file, this is included with the file so the software can check to see if file is intact. • The check sum is updated each time the method is saved. • The method files are tested for valid check sum on opening. • If the check sum of one file is not valid, an error message box is displayed and the method is not opened.

  4. HAMILTONVENUSSecurity Settings • Checksum Verification • Benefits: • Prevents editing of files outside Hamilton software, which would circumvent other security settings. • Detects file corruption.

  5. HAMILTONVENUSSecurity Settings • List Used Files • This lists all the files that were used in the method at the end of the trace file when a method runs.

The user can be changed while the application is running. • Operating System – User access is determined by logging on to the computer. Privileges are set in ‘Computer Management \ System Tools \ Local Users and Groups \ Groups \ …’ • Using both types of authentication systems a user can still delete the method files via the windows interface. The customer’s IT department would need to lock these files.

  20. HAMILTONVENUSSecurity Settings Warning When using the Hamilton Authentication System and running a method that appends, or writes to a file, a user with a low level of access, e.g. lab operator can be prevented from running the method. Error message: Cannot update. Database or object is read-only. To overcome this the customer’s IT department need to change the access rights of the files or folders to give ‘write’ access.
