A1: The most important aspect of data base security is securing the database for a wide-range of applications. it can be achieved by implementing suitable data base security policies and guidelines. These policies include:

The business rules and enterprise security guidelines should be strictly followed.

The data types should be secured based on their sensitivity. These data types may be of sensitive nature like personal information, financial information, trade secrets, health information, and customer information.

The system should be secured with firewalls.

All the database users need to be authorized and authenticated for accessing the system.

The data should be encrypted before storing.

The data should be stored in secured database. The database should be located in the server that is protected with a firewall.

A1: If a company is looking to protect the data in its database then the IT department should be in a position to implement the data base security policies. For example, the company may not allow a remote access to the database. Thus, the business rules should be strictly followed. If the company’s database is the main source of the company’s business, then it should be secured with firewalls. All the data that are stored in the database should be encrypted with suitable tools.

A1: There are various factors to be considered before implementing data base security. It should be considered how to protect data with high confidentiality, no unauthorized user should be able to access the database, data should be encrypted or hidden from unintended users, and data should be protected from external and internal threats. The data should be stored in secure environment and it should be protected from unauthorized access and misuse. All the above-mentioned factors need to be considered for the data base security. There are three ways of achieving data base security:

A5: There is a high need and its necessary to protect the database with high security encryption. Otherwise, internal or external threat may lead to reputation damage, brand erosion, financial loss, consumer confidence disintegration, non compliance of government and industry regulation. Data base security protects the data from

A3: When data are breached, organisations may be required to comply with security regulations. For example, the data may need to be erased or secured in such a way that it cannot be reused or sold.

A4: Data base security is concerned with the data protection from all kinds of threats and in particular from malicious attacks. The security can be done by several ways like encryption, authentication, authorization and access control, user & application based access controls, firewalls, monitoring, intrusion detection, etc.
