The main concepts of information security are confidentiality, integrity, and availability. In English, this is referred to as CIA (Confidentiality, Integrity, Availability).

Thus, an information security system must ensure that commercial information is protected from unauthorized access, accidental deletion, or modification, while ensuring that each employee has access to the data necessary for their work.

To reduce the risks associated with data leaks, several tools are used to achieve these goals.

Reducing risks related to data leaks while simplifying compliance with requirements for ensuring secure data handling can be achieved through methods such as encryption at the data transmission and storage levels, managing strong passwords, controlling privileged user access, and continuous monitoring of suspicious activities.

Multi-Level Database Protection

Data protection is ensured by minimizing the risks of data leaks and securing user accounts.

• Access control is the primary step to ensure complete data protection. This is achieved by securing user accounts with strong passwords and implementing two-factor authentication and robust device identification. Database protection is impossible without password management, where passwords are stored only in a transformed, secure form using one-way hashing, which is crucial for maintaining security. Authentication, combined with well-structured authorization, best protects critical data from malicious actors.
• By separating user responsibilities within the system, you prevent privilege abuse and minimize accidental or intentional changes to the information contained in the database. Configuring access restrictions is a highly effective measure, ensuring that average users cannot even be aware of the existence of information not intended for them.

Access control can be configured by setting confidentiality levels for system objects and users, as well as by using role-based access control.

• Ideally, continuous monitoring should be conducted to track active database activities. This allows you to monitor user activity in the network and actions initiated directly within the database. In case of suspected account compromise, you can temporarily restrict the employee’s access to data.

• Ensure the security of cloud data. Data encryption is one of the most effective methods of ensuring data security. Encrypting information stored in the database makes it unreadable to those who do not possess the encryption keys.
• Traffic between the client and server must also be protected during data transmission, as there is a risk of information interception during transit. Using the HTTPS protocol with an SSL certificate ensures that system data is protected from interception by third parties during transmission.
• Efficient storage and physical protection of data, which includes quick search, data updates, ensuring information confidentiality, and more, is achieved by storing data on physically separate servers. Ensuring the preservation of information stored on these servers is addressed by implementing a backup policy, which involves daily automatic database backups to separate servers.

By deploying cloud databases, you can significantly reduce company costs, free up staff, and assign them to other important tasks, while also ensuring organizational flexibility.

Note that using the cloud introduces additional risks related to the expansion of the network perimeter and the increase in surface threats. By following recommendations that ensure database security, the cloud can help you build a robust defense with minimal costs and maximum efficiency.
