What is a recommended action to take if unauthorized attempts to connect to a database server are detected?

• A. Increase the number of users with access
• B. Implement port security to block the default port
• C. Make the database accessible for testing
• D. Notify all users immediately

Answer: (B)

Implementing port security to block the default port is a crucial step when unauthorized attempts to connect to a database server are detected. By doing so, you can help mitigate potential security threats by restricting access to the database server through its communication ports. Many database servers have well-known default ports that are commonly targeted by attackers, and closing or securing these ports can reduce the risk of unauthorized access and enhance the overall security posture of the server. The approach of changing network configurations, such as blocking default ports, makes it more difficult for unauthorized users to find and connect to the database. Additionally, enforcing strict access controls on critical services helps to guard against attacks such as port scanning and brute-force attempts. Other options may not effectively address the immediate security concern. Increasing the number of users with access could inadvertently widen the attack surface, while making the database accessible for testing can expose it to more vulnerabilities. Notifying all users immediately may create unnecessary panic without necessarily improving the security of the database itself. Therefore, focusing on security measures like implementing port security is a more direct and effective response to unauthorized access attempts.
