AWS Community Day Romania: Live Hacking Demo on AWS Environments

Join the AWS Community Day Romania on the 10th of April for an exciting lineup of talks on AWS. Eduard Agavriloae, Director Cloud R&D @ OffensAI, will be presenting a live demo on how AWS environments get hacked and how to defend them. This event is a must-attend for anyone interested in cloud security and ethical hacking.

You Should Know:

1. AWS CLI Command to Check Security Groups:

aws ec2 describe-security-groups --group-names <your-security-group-name>

This command helps you review the security groups associated with your AWS instances to ensure they are properly configured.

2. AWS CLI Command to List IAM Policies:

aws iam list-policies

Use this command to list all IAM policies in your AWS account, which is crucial for understanding who has access to what resources.

3. AWS CLI Command to Enable CloudTrail Logging:

aws cloudtrail create-trail --name <trail-name> --s3-bucket-name <bucket-name> --is-multi-region-trail

Enabling CloudTrail logging is essential for tracking API calls and detecting unauthorized access.

AWS CLI Command to Check for Public S3 Buckets:
```
aws s3api list-buckets --query "Buckets[].Name"
aws s3api get-bucket-acl --bucket <bucket-name>
```
These commands help you identify any S3 buckets that are publicly accessible, which could be a security risk.
AWS CLI Command to Encrypt an EBS Volume:
```
aws ec2 enable-ebs-encryption-by-default
```
Encrypting your EBS volumes ensures that your data is secure, even if the physical disk is compromised.
AWS CLI Command to Check for Unused Elastic IPs:
```
aws ec2 describe-addresses --query "Addresses[?AssociationId==null].PublicIp"
```
This command helps you identify and release any unused Elastic IPs, which can help reduce costs and improve security.

7. AWS CLI Command to List EC2 Instances:

aws ec2 describe-instances --query "Reservations[].Instances[].InstanceId"

Regularly listing your EC2 instances helps you keep track of your resources and ensure that no unauthorized instances are running.

AWS CLI Command to Check for MFA on Root Account:
```
aws iam get-account-summary | grep "AccountMFAEnabled"
```
Ensuring that MFA is enabled on your root account is a critical security measure.

9. AWS CLI Command to List Lambda Functions:

aws lambda list-functions

This command helps you review all Lambda functions in your account, which is important for understanding your serverless architecture.

AWS CLI Command to Check for Publicly Accessible RDS Instances:
```
aws rds describe-db-instances --query "DBInstances[?PubliclyAccessible==true].DBInstanceIdentifier"
```
This command helps you identify any RDS instances that are publicly accessible, which could be a security risk.

What Undercode Say:

AWS security is a critical aspect of cloud computing, and understanding how to protect your environment is essential. The live hacking demo at the AWS Community Day Romania will provide valuable insights into both offensive and defensive strategies. By using the AWS CLI commands provided, you can enhance your security posture and ensure that your AWS environment is well-protected. Always stay updated with the latest security practices and regularly audit your AWS resources to mitigate potential risks.
