What is database security?
Database security is a process or technique that protects the database management system from accidental and intentional threats. Security concerns are not just about the data that is in an organization’s database: they can affect other parts of the system, which can ultimately affect the structure of the database.
As a result, database security includes human resources, software parts, hardware components, and data.
The types of database security that your business should use include protecting infrastructure (such as networks, databases, and servers), securely configuring DBMS, and accessing data.
Requirements to obtain adequate security often ignored or neglected in the past; it is now being thoroughly checked by various organizations.
We consider database security in the following situations:
1) Loss of data privacy.
2) Losing secrets or privacy.
3) Fraud and theft.
4) Loss of data integrity.
5) Decreased availability.
What is Threat?
Any event or situation, whether accidental or intentional, causes harm, which may reflect a negative impact on the structure of the database.
A threat is an event or situation that involves an action, situation or person that may harm an organization and its database.
Types of Database Security:
Database security includes multiple controls including Database Management System (DBMS) configuration, system tightening, security monitoring, and access control. These security controls help to manage the parasitic situation of the security protocol.
1.System monitoring and hardening:
The architecture provides additional access to the Database Management System (DBMS). It is important that the system is permanently patched, tightened using known security configuration standards, and monitored for access, including threats.
2.Database management system (DBMS) Configuration:
It is important that the Database Management System (DBMS) is properly tightened and configured to take advantage of security features and restrict privileged access, which can lead to incorrect configuration of expected security settings. Monitoring the DBMS configuration and ensuring the appropriate conversion process helps ensure that the configuration remains consistent.
3.Data in Transport:
This is a somewhat decent idea and not complicated at all. This is usually referred to as a security system that ensures that no one can interpret or read the data or information when moving between different networks and configuring servers.
The primary purpose of protecting this particular system is to limit any possible limitations of server breaches or unauthorized access at any time. As such, this specific data settings is also known as access control.
Every node of data entering and accessing the secure server system is non-readable and encrypted from until it is securely stored in the secure system database or is not displayed to the user has requested data.
Such data security is on the next line and should be implemented after the completion of the data contained in the transport protocol. There are different layers to this security protocol.
In general, this way you verify that the user is what they say they are. Simply, this request or query is being submitted by an authorized dedicated and an official user.
Different methods can be used for authentication, such as using a two-way authentication method that integrates different layers of security into a mix and authenticates a particular user, and gives them access to data.
If the authentication process is not applied during the creation of the database, then any illegal person or hacker can easily gain access to the database and servers and as a result, it will cause havoc.
Two-way authentication tests the user’s authenticity in two ways. The user first enters their username and password and then adds a verification code. Users can only access data when both credentials match.
The next and most important step in database security is an authorization (permission). This layer of protection ensures that it identifies specific elements to which the dedicated user has access.
If necessary, this restriction may apply to a dedicated user, and their access may be limited to a general overview of the system.
For example, a simple user in an organization may only have access to the database to enter daily expenses or other financial information but we do not want to grant the right to edit or delete any data in the database. So as to limit the access or privileges is called authorization
This safety measure is most important because it ensures that no one is stumbling or peeping into unauthorized areas or looking for parts they are not looking for. The level of permissions assigned to a specific user can be customized according to the needs.
After encrypting and applying the restrictions to the database management system. Therefore, you still need to audit the system to make sure that whatever was in your inventory, such as important information that was lost in the hack attempt. Regular audit reports should ensure that you have a proper record of everything in the end.
7.Backup and Recovery:
Recovery is also considered as a basic system related to database security. You need to make various backups of the data in the database, so that it is not completely lost in case of any systematic hack or breach by a hacker. You also need to make sure that the backup files are completely encrypted and protected, and that there are 2 additional copies are stored at different places.
Database security is very important for any database management system. In this post, we’ve outlined the different security types that can help protect your database.
