• LET‘S BUILD A NEW ENTRY GATE FOR THE PALACE


    Overview
    Once upon a time, Emperor Akbar organized a party in his palace. He invited all the cabinet members and subjects to the party. Everything was going well on the day of the party but suddenly a fight broke out between his cabinet members and the subjects at the entry gate.

    When Emperor Akbar came to know about this, he immediately called Birbal (You) and asked you to investigate deeply and find a solution.

    On further investigation, Birbal (You) found that the members of the cabinet and the subjects were entering through the same gate, and there was a sudden stampede at the entrance of the palace.

    To solve this problem, Birbal (You) decided to use different entrances for cabinet members and subjects.

    The emperor was very happy with this solution and ordered you to work on the solution immediately.

    Background
    In this task, you are going to modify the responsibilities (Allow only HTTPS access) of old Guard (Security Group) to maximize the security of Palace (EC2).

    Your Task
    Modify the “Gate 1 Guard (Security Group 1)” Security Group to allow traffic only on TCP port 443 from all IPv4 addresses.

    Inventory
    EC2 - Security Groups
    Services you should use
    EC2 - Security Groups

    The task will complete once you correctly modify the “Gate 1 Guard” security group. So now single EC2 instance has two network interfaces. One interface is publicly accessible on port 443 and another is only accessible via private ip on port 80. We can use second interface for internal traffic or management purpose.

    There is no need to explain. The topic is very clear. As long as you are not lazy, follow the steps
