Which of the following acts as an instance-level firewall to control (CLF-C02)
Which of the following acts as an instance-level firewall to control inbound and outbound access?
A) Network access control list
B) Security groups
C) AWS Trusted Advisor
D) Virtual private gateways
Solution
Correct answer: B) Security groups.
Security groups act as virtual firewalls for your Amazon EC2 instances to control inbound and outbound traffic. You can specify rules to allow traffic to and from specific IP addresses, ports, and protocols. Security groups are stateful, meaning that if you allow an inbound request from a specific IP address, the response traffic is automatically allowed regardless of outbound security group rules.
