To control access to Amazon EC2 instances using AWS Systems Manager Session Manager based on specific tags:

Attach an IAM Policy to Users or Groups: Create and attach an Identity and Access Management (IAM) policy to the IAM users or groups who need access to the EC2 instances. This policy should specify the permissions required to use Session Manager to start sessions with the instances.

Create an IAM Policy with Tag-Based Conditions: Create an IAM policy that includes a condition element to allow access to EC2 instances based on specific tags. This policy can be designed to grant the ssm:StartSession permission only for instances that match certain tags, as defined in the condition block of the IAM policy. Here is a sample condition block that could be used:

"Condition": {

"StringEquals": {

"ec2:ResourceTag/YourTagName": "YourTagValue"

}

}

This ensures that only authorized users can initiate sessions with instances that have the specified tags, enhancing security and operational management.

By implementing these policies, you ensure that only the appropriate personnel have the controlled access required, based on the specific business needs and security guidelines.

Here are the steps to configure an Amazon S3 bucket to serve a static error page in the event of a failure at the primary site:

Log in to the AWS Management Console and navigate to the S3 service in the us-east-2 Region.

Find the existing S3 bucket named lab-751906329398-26023898.com and click on it.

In the "Properties" tab, click on "Static website hosting" and select "Use this bucket to host a website".

In "Index Document" field, enter the name of the object that you want to use as the index document, in this case, "index.html"

In the "Permissions" tab, click on "Block Public Access", and make sure that "Block all public access" is turned OFF.

Click on "Bucket Policy" and add the following policy to allow public read access:

{

"Version": "2012-10-17",

"Statement": [

{

"Sid": "PublicReadGetObject",

"Effect": "Allow",

"Principal": "*",

"Action": "s3:GetObject",

"Resource": "arn:aws:s3:::lab-751906329398-26023898.com/*"

}

]

}

Now navigate to the Amazon Route 53 service, and find the existing hosted zone named lab-751906329398-26023898.com.

Click on the "A record" and update the routing policy to "Primary - Failover" and add the existing ALB as the primary record.

Click on "Create Record" button and create a new secondary failover alias record for the domain lab-751906329398-26023898.com that routes traffic to the existing S3 bucket.

Now, when the primary site (ALB) goes down, traffic will be automatically routed to the S3 bucket serving the static error page.

Note:

You can use CloudWatch to monitor the health of your ALB.

You can use Amazon S3 to host a static website.

You can use Amazon Route 53 for routing traffic to different resources based on health checks.

You can refer to the AWS documentation for more information on how to configure and use these services:

"When you enable log file integrity validation, CloudTrail creates a hash for every log file that it delivers. Every hour, CloudTrail also creates and delivers a file that references the log files for the last hour and contains a hash of each. This file is called a digest file. Validated log files are invaluable in security and forensic investigations"
