aws ec2 describe-security-groups
Step 2: Identify the security group that has unrestricted MySQL access. You can filter the results using the following command:
This command will list all the security groups that have unrestricted MySQL access.Step 3: Once you have identified the security group, run the following command to revoke the MySQL access:
Replace <security-group-id> with the ID of the security group that you want to remediate.Step 4: Verify that the MySQL access has been revoked by running the following command:
This command will list the details of the security group that you have remediated.That’s it. You have successfully remediated the unrestricted MySQL access issue in AWS using AWS CLI.
Using Python
To remediate unrestricted MySQL access in AWS using Python, you can follow these steps:
Loop through each RDS instance and modify its security group to remove unrestricted MySQL access:
Copy
Ask AI
for instance in instances: db_instance_identifier = instance['DBInstanceIdentifier'] db_security_groups = instance['DBSecurityGroups'] for security_group in db_security_groups: if security_group['DBSecurityGroupName'] == 'default': try: response = rds.revoke_db_security_group_ingress( DBSecurityGroupName='default', EC2SecurityGroupId=security_group['EC2SecurityGroups'][0]['EC2SecurityGroupId'], CIDRIP='0.0.0.0/0', DBProtocol='tcp', DBPortNumber=3306 ) print(f"Revoked unrestricted MySQL access for {db_instance_identifier}") except ClientError as e: print(e) exit(1)
This code will loop through each RDS instance and its associated security groups. If the default security group is found, it will revoke any inbound rules that allow unrestricted MySQL access (i.e. from any IP address). The code will print a message for each instance where unrestricted MySQL access was revoked.
