Description: Data warehouse security refers to the protection of data stored in a data warehouse against unauthorized access. This involves implementing various security measures to safeguard the integrity, confidentiality, and availability of information. Data warehouses are systems used to store large volumes of data from various sources, facilitating analysis and processing. Security in these environments is crucial, as the data may contain sensitive and valuable information for organizations. Key features of data warehouse security include access control, data encryption, auditing and activity monitoring, as well as the implementation of robust security policies. The relevance of this security lies in the growing amount of data that organizations generate and store, making them vulnerable to cyberattacks and data breaches. Therefore, ensuring the security of data warehouses not only protects information but also helps maintain customer trust and comply with data protection regulations.
