What is a Database vulnerability?

A database vulnerability is a weakness or flaw in a database management system (DBMS) that can be exploited by malicious actors or unintentionally exposed, leading to unauthorized access, data breaches, data manipulation, or other security-related issues

Employee-Based Threats

Description: Threats posed by individuals with authorized access to a system, such as employees, contractors, or business partners.

Prevention:

  • Strong access controls
  • Regular security awareness training
  • Monitoring user activity
  • Regular background checks

Default and Weak Passwords

Description: Using default, blank, or weak passwords can make systems vulnerable to unauthorized access.

Prevention:

  • Enforcing strong password policies
  • Regular password changes
  • Disabling default accounts

SQL Injection Attacks

Description: A type of cyberattack where malicious SQL statements are inserted into an entry field for execution.

Prevention:

  • Input validation and sanitization
  • Prepared statements or parameterized queries
  • Least privilege principle for database users

Potential Security Breaches Due to Excessive Permissions

Description: Granting excessive privileges to users or groups can increase the risk of unauthorized access and data breaches.

Prevention:

  • Principle of least privilege
  • Regular review and auditing of user permissions

Unpatched Database Vulnerabilities

Description: Outdated database software with unpatched vulnerabilities can be exploited by attackers.

Prevention:

  • Timely application of security patches
  • Regular software updates

Audit Trail Tracking

Description: Tracking user activity and system events can help identify and investigate security incidents.

Prevention:

  • Implementing robust audit trail systems
  • Regular review and analysis of audit logs

Attacks performed on Database Backups

Description: Attackers can target database backups to gain access to sensitive data.

Prevention:

  • Encrypting backups
  • Storing backups securely
  • Regular testing of backup and restore procedures

Weak Encryption Strategies and Data Breaches

Description: Weak encryption or lack of encryption can lead to data breaches and unauthorized access.

Prevention:

  • Strong encryption algorithms
  • Regular key management
  • Data loss prevention (DLP) solutions

Denial-of-Service Attacks on Database Management Systems

Description: Overwhelming a database system with excessive traffic to render it inaccessible.

Prevention:

  • Network security measures (firewalls, intrusion detection systems)
  • Load balancing
  • Capacity planning

Inadequate Database Security and Regulatory Risk

Description: Using outdated security tools and failing to comply with data protection regulations can expose organizations to legal and financial risks.

Prevention:

  • Regular updates of security tools
  • Adherence to relevant data protection regulations
  • Data privacy impact assessments
