To remediate the issue of unrestricted Oracle access in AWS, you can follow the below steps:
Open the AWS Management Console and navigate to the RDS service.
Select the affected RDS instance and click on the “Modify” button.
Scroll down to the “Network & Security” section and click on the “Additional Configuration” tab.
In the “Additional Configuration” tab, locate the “Publicly Accessible” option and set it to “No”.
Next, locate the “VPC Security Group” option and select the appropriate security group that allows access only to the required IP addresses or CIDR ranges.
Click on the “Continue” button and review the changes. If everything is correct, click on the “Modify DB Instance” button to apply the changes.
After the changes have been applied, verify that the RDS instance is no longer publicly accessible and that access is restricted to the required IP addresses or CIDR ranges.
By following these steps, you can remediate the issue of unrestricted Oracle access in AWS and ensure that your RDS instance is secure.
This command will display the details of the security group, including the inbound rules.
Finally, you should test the Oracle access to ensure that it is restricted as expected. If necessary, you can modify the security group rules further to allow access only from specific IP addresses or networks.

for sg in security_groups: for rule in sg['IpPermissions']: if rule['IpProtocol'] == 'tcp' and rule['FromPort'] == 1521 and rule['ToPort'] == 1521 and rule['IpRanges'] == [{'CidrIp': '0.0.0.0/0'}]: print(f"Security group {sg['GroupId']} has unrestricted Oracle access!")
If you find a security group with unrestricted Oracle access, use the revoke_security_group_ingress method to remove the rule:
