Question

Describe some of the threats and vulnerabilities to a database that must be planned for. Build a security checklist that could be used by a database administrator. Explain how often it should be used and the security issues that could be minimized.

Answer 1

Database threats include SQL injection and malware, with a security checklist involving updates, access controls, and backups being critical. This checklist should be used regularly to minimize unauthorized access and data breaches.

Step-by-step explanation:

Threats and vulnerabilities to a database include attacks such as SQL injection, malware, insider threats, and physical damage, which can lead to data breaches. A comprehensive security checklist should be implemented to protect against these vulnerabilities.

It includes regular updates and patches to database software, strong authentication measures, access controls, monitoring and auditing of database activity, data encryption, backups, and disaster recovery plans. This checklist should be reviewed and utilized regularly, ideally as part of a routine security protocol that is checked weekly or after any significant change in the system. This practice is crucial in minimizing security issues such as unauthorized data access, data corruption, and data loss.

The security checklist should be used frequently to ensure that no new vulnerabilities have been introduced and that all protective measures are functioning correctly. By doing so, database administrators can address the key security concerns, like the unauthorized use of data, information theft, and potential system failures, effectively minimizing the risk of data breaches.
