Is the data secure?
- The application uses Microsoft Access user level security as described on microsoft.com. This is
more secure than the simple database password that is easily defeated. This like most security schemes, is not
absolute security.
- Each record is timestamped with the user's network userid and time when updated.
- There are two user levels; user and super. You can set the screen color to see which level is logged in more easily.
Reports, form fields and buttons can be restricted to allow access only by the super user. The database may
immediately quit after opening the first time after a programmer has made a change in the application.
This is to reset essential properties for users. You should be able to login successfully on the
second attempt.
- The back-end data tables are encrypted and protected with the same security. Users
cannot access the tables except through the data entry forms and reports.
- Data queries for most reports can be saved as .CSV or .XLS files for Excel. The Super user
can also import to most tables. View each table before importing it.
- Make backups at least daily. Store a copy offsite periodically.
- Only allow trusted users validated with a Windows NT account password to have access to the folder where
the application resides.
- If you run the website version of this application, follow the installation
instructions carefully and keep the operating system current by applying the Windows Updates and
hotfixes identified by hfnetchk.exe (available free on microsoft.com). Keep the antivirus software
updates current and restrict access to non-essential ports using a hardware or software based
firewall. Implement a backup and recovery strategy for the server that enables you to quickly
recover from disaster.
