To design a high-traffic static website that is highly available and provides low latency globally, you can use Amazon S3, CloudFront, and Route 53. This solution leverages the global edge locations of CloudFront to deliver content with low latency.

Create an Amazon S3 Bucket:

Open the S3 console at Amazon S3 Console.

Create a new bucket and upload your website content.

Configure S3 for Static Website Hosting:

Go to the Properties tab of your bucket.

Enable Static website hosting and set the index document (e.g., index.html).

Create a CloudFront Distribution:

Open the CloudFront console at Amazon CloudFront Console.

Create a new distribution and set the S3 bucket as the origin.

Configure distribution settings, including caching behaviors and SSL/TLS settings.

Create Route 53 Alias Record:

Open the Route 53 console at Amazon Route 53 Console.

Select the hosted zone for your domain.

Create a new record set, choose ALIAS as the record type, and point it to the CloudFront distribution.

To generate a monthly report showing all S3 buckets and their compliance with the requirement to block public read access, the SysOps administrator can take the following steps:

Create an AWS Config Aggregator:

Create an AWS Config aggregator in an aggregator account. Use the organization as the source to aggregate AWS Config data across all accounts in the organization.

The rejected traffic in the flow logs is due to the network ACL associated with the subnet not allowing outbound traffic for the ephemeral port range.

Network ACLs:

Network ACLs act as a firewall for controlling traffic in and out of one or more subnets.

By default, NACLs allow all inbound and outbound traffic, but custom NACLs require specific rules to allow traffic.

Ephemeral Ports:

Ephemeral ports are temporary ports used for client-side communication. The default range is 1024-65535.

Ensure that the network ACL allows outbound traffic on these ports.

Steps to Resolve:

Check the network ACL rules for the associated subnet.

Add outbound rules to allow traffic from the ephemeral port range (1024-65535).

Amazon GuardDuty is a threat detection service that continuously monitors for malicious activity and unauthorized behavior to protect AWS accounts and workloads. It provides detailed monitoring for unauthorized access attempts, including console login attempts from unusual locations.

Amazon GuardDuty:

GuardDuty analyzes VPC flow logs, AWS CloudTrail logs, and DNS logs to detect suspicious activity.

It generates findings, such as UnauthorizedAccess

/ConsoleLoginSuccess, to alert administrators about potential security issues.

Setup:

Enable GuardDuty in your AWS account.

Configure GuardDuty to monitor unauthorized console logins.

Set up notifications for the relevant findings to alert administrators.
