Oracle Cloud Platform Data Integration 2020 Specialist — Question 4

A leading insurance firm is hosting its customer portal in Oracle Cloud Infrastructure (OCI) Container Engine for Kubernetes with an OCI Autonomous Database.
Their support team discovered a lot of SQL injection attempts and cross-site scripting attacks to the portal, which is starting to affect the production environment.
What should they implement to mitigate this attack? (Choose the best answer.)

Answer options

• A. Network Security Lists
• B. Network Security Groups
• C. Network Security Firewall
• D. Web Application Firewall

Correct answer: C

Explanation

The correct answer is C, Network Security Firewall, as it provides a robust defense against various types of attacks, including SQL injection and cross-site scripting. Options A and B, Network Security Lists and Network Security Groups, are more focused on controlling traffic flow and do not specifically address application-layer attacks. Option D, Web Application Firewall, is also a good option, but the question specifically asks for the best answer, which in this context is the Network Security Firewall.
