The article will elaborate 5 easy tips to secure MS Access Database against a range of security threats.
Data is a resource and like any other resource, it has its own value and a financial worth. Had it not been significant, companies all across the globe wouldn’t be spending millions on data security. Data protection has become significant and an urgent need of the hour. Although MS Access provides basic level security to your data but adding a few more layers ensures the safety and protection of the data. Here are a few simple harmless tips to fortify your Access Database.
1. Splitting of the Database
A split database is less vulnerable than a single database containing all the data and objects. When you split database, you create a backend and a frontend storing tables and objects separately, and later linking them through tables. It prevents the users on frontend to change the table design in backend.
Splitting database can be selected from Database Utilities in the Tools Menu.
2. Hiding Objects to add security
Hiding objects like tables, forms and queries can be helpful in many cases. Hiding objects doesn’t mean that the objects would be deleted; users can obviously access them anytime.
Users should however remember that this option will only move the object out of sight, any person with experience on Access can unhide the objects easily. So only hide the objects which are important. To hide Objects, one can simply right click the object and check Hidden Attribute option from the properties.
3. Error Handling in Code Protection
The document should have proper Error handling and the user should try best to inhibit the default message with debug option. Any user while using your document, if faces an error and a display box with debug option, he or she may accidently remove the entire code causing a heavy data loss. Thus, proper error handling should be there to avoid such cases.
4. Password Protection
The best way to secure your database is to add a password protection which could be a PIN number required while accessing database. There are however third party software that can crack the password but it’s still an efficient option. Users can password-protect their databases by opening them in Exclusive Mode (from Open Dialogue box) and choosing Security option under the Tools Menu. There is an option of Set Database Password where users can enter a password. Users can remove the password too by following the same procedure.
5. Protection using File Formats
MS Access allows the users to save their documents in various file formats. It’s advised to use mde and accde format from the security point of view. These file formats are actually execute only versions, thus normal users can’t access the code easily. Users can’t even interfere with the designs of the objects thus it largely prevents the misuse of data and chances of ending up with a corrupted Access database file. Also, use these formats for the frontend (and not backend) if you are using spilt database. This format however is inefficient in protecting the database objects.
