Frequently Asked Questions
Q1: What is data base security?
A1: To protect the data base from internal and external threats, organisations take various measures. Ensuring these measures is called data base security. Since a lot of important information are being sent through computer network anyone may hack or breach the security and misuse the data for personal needs. Hence it is necessary to protect the data from possible threats.
Q2: What are the different levels and security solutions of data base security?
A2: Primarily, there are 3 major layers of database security.
- Data base level takes place within the database where the data exists. Solutions include tokenisation, masking and encryption
- Access level where the security focuses on having a control over who may access certain data in a computer system. Solutions include permissions and access control lists
- Perimeter level decides who can and cannot pass through databases. Solutions include virtual private networks and firewalls
Q3: What are the best practices of data base security?
A3: Best approaches towards database security include web application and firewalls, physical database security, data base encryption, isolate sensitive database, manage password and permissions, Change management, Database auditing etc.
Q4: What is database vulnerability?
A4: A platform which collects, maintains, and disseminates information about possible vulnerabilities targeting real computer system is called vulnerability database.
Q5: What is the importance of database 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
- weak authentication
- Privilege abuse
- Deployment failure
- Backup data exposure
- Database injection attacks
- Unmanaged sensitive data
- Platform vulnerabilities
- Excessive privileges
