A secure data repository is an isolated storage location in which data is kept for analytical or reporting needs. There are a variety of different types of data repositories exist which include data warehouses, lakes and marts, each with their distinct advantages and problems.
Information stored in a data repository is often aggregated from various systems, such as point-of-sale and ERP systems, and is then centralized for analysis and reporting. This can help companies manage large volumes of data, and ensure the data is accurate. However, as the volume of data increases security risks can increase as well. To reduce the risk, it is important to implement solid practices for managing data that take an approach that is multi-faceted and secure to safeguard data.
For example, an encrypted data repository must have access rules that permit only authorized users who have legitimate business reasons to modify or transmit data. These rules should also address critical concerns regarding data management, for instance retention of data. A secure data repository must also support digital signatures or other methods to verify authenticity of information.
For a secure repository of data, it is also important to ensure that the software is scalable and able to handle the growing amount of data. It is also crucial that the system be properly backed up and protected from malicious attacks. A single system crash or hacking attack could erase all the data stored in the database.
