Patch Management
Regularly applying software patches for the database management system ensures protection against known vulnerabilities that could be exploited by attackers.
Use of Firewalls
Implementing database firewalls can prevent unauthorized access and protect the database from various types of attacks by monitoring and controlling incoming and outgoing traffic.
Data Masking
Masking sensitive data in the database ensures that non-privileged users can work with data without accessing sensitive information, which helps in maintaining privacy and security.
Incident Response Plan
Having a well-defined incident response plan enables a quick and effective response to security breaches, minimizing potential damage and laying out steps to recover and secure the database.
Access Controls
Implementing granular access controls ensures that users have the minimum level of access required to perform their duties, following the principle of least privilege.
Audit Trails
Keeping detailed logs of database activities can help track changes, access patterns, and potentially malicious activities, enabling accountability and forensic analysis.
Regular Security Assessments
Periodically assessing the security of the database helps identify and mitigate new vulnerabilities, ensuring that the system adapts to evolving threats.
Secure Authentication Mechanisms
Using strong authentication methods such as multi-factor authentication (MFA) can vastly reduce the risk of unauthorized database access by verifying user identity more robustly.
Regular Backups
Maintaining frequent backups of the database helps in data recovery in case of a catastrophic failure or data breach. It's key to loss prevention and maintaining data integrity.
Input Validation
Validating user inputs can prevent SQL injection and other forms of data manipulation by ensuring that only properly formatted data is entered into the system.
Data Encryption
Encryption of data at rest and in transit protects sensitive information from unauthorized access. It ensures that even if data is intercepted or accessed, it's unreadable without the appropriate decryption keys.
SQL Injection Prevention
Using prepared statements and stored procedures can help prevent SQL injection attacks by separating SQL logic from user inputs, thus preventing attackers from manipulating SQL queries.
