Study Notes
Database Security Overview
- Database security involves processes, tools, and controls designed to protect databases from accidental and intentional threats.
- The goal is to safeguard sensitive data, maintaining confidentiality, availability, and integrity of the database.
Types of Database Security
- Information protection: Strategies and practices safeguarding sensitive data.
- Network security: Protecting databases from unauthorized network access.
- SQL management: Controls over database-query language.
Firewalls
- Firewalls act as the first line of defense.
- They logically separate and restrict network traffic.
- Customizable to enforce organizational data security policies.
Authentication
- Authentication verifies a user's identity.
- Users prove their identity by providing correct user IDs and passwords.
Authorization
- Allows users specific access to data objects and database operations.
- Users can read but not modify or delete data, modify but not delete data, or delete data, depending on their assigned role.
Threat Detection
- Identifies anomalous database activities indicating potential security threats.
- Reports suspicious events to administrators.
Data Encryption
- Converts data into a coded format to prevent unauthorized access.
Database Backup and Recovery
- Creates data copies to restore in case of loss or corruption.
Physical Security
- Protects physical assets like servers through access controls and surveillance.
Importance of Database Security
- Data Theft: Databases are prime targets for cyberattacks due to valuable, sensitive information stored, like customer records, credit card, bank account, and personal identification numbers.
- Damage to Business and Brand Reputation: Companies with poor database security face customer hesitation to do business, damage to reputation, decline in sales, and customer churn.
- Revenue Loss: Data breaches can halt or slow business operations and revenue generation until the issue is resolved.
- Increased Costs: Data breaches incur millions of dollars in expenses, including legal fees, assisting victims, recovering data, potentially paying ransomware fees to hackers.
- Data Breach Violation Penalties: State and local agencies may impose fines and, in some cases, require compensation for customers when data is not protected.
