Determine your network architecture: Start by understanding your network requirements and designing the overall network architecture in AWS. This can include the use of Virtual Private Cloud (VPC), subnets, and security groups.
Create a VPC: Begin by creating a VPC in AWS to provide a logically isolated section of the cloud where you can launch your resources. Define the IP address range for your VPC based on your needs.
Configure subnets: Divide your VPC into subnets to separate different components of your network. Create at least three subnets: one for the internet-facing zone, one for the DMZ, and one for the internal zone.
Set up internet gateway: Attach an internet gateway to your VPC to allow communication between your VPC and the internet. This enables your internet-facing zone to receive incoming traffic.
Deploy BAGUSSADMZSRV instance in the DMZ subnet: Launch the BAGUSSADMZSRV instance in the DMZ subnet. This subnet should be placed between the internet-facing subnet and the internal subnet, effectively isolating it from both.
Configure security groups: Define and configure security groups to control inbound and outbound traffic for the BAGUSSADMZSRV instance. Specify the necessary protocols and ports required for media operations and restrict access based on the principle of least privilege.
Use Network ACLs: Implement Network ACLs to provide an additional layer of security by controlling traffic at the subnet level. Configure Network ACL rules to allow necessary traffic to and from the BAGUSSADMZSRV instance while blocking unauthorized access.
Implement AWS WAF (Web Application Firewall): If the BAGUSSADMZSRV instance is serving web content, consider using AWS WAF to protect against common web-based attacks. AWS WAF can help filter out malicious requests before they reach your instance.
Set up NAT Gateway: For instances in the DMZ subnet that require outbound internet access, set up a NAT Gateway. This allows outbound traffic while keeping your internal subnet private.
Enable AWS CloudWatch Logs: Enable CloudWatch Logs to capture logs from the BAGUSSADMZSRV instance, VPC Flow Logs, and other relevant resources. This helps monitor and analyze network traffic and security events.
Implement AWS GuardDuty: Enable AWS GuardDuty, a threat detection service, to continuously monitor your AWS environment for malicious activity. GuardDuty uses machine learning algorithms to analyze log data and detect anomalies.
Regularly update and patch instances: Keep the BAGUSSADMZSRV instance and other resources up to date with the latest patches and security updates provided by AWS. Implement automated patch management solutions to streamline this process.
Implement backup and disaster recovery: Set up regular backups of the BAGUSSADMZSRV instance's data using services like Amazon S3 or EBS snapshots. Define and test disaster recovery procedures to ensure quick recovery in case of an incident.
Remember to follow AWS security best practices, consult AWS documentation, and consider engaging with AWS Certified Solutions Architects or security professionals to ensure your AWS DMZ setup with the BAGUSSADMZSRV aligns with your specific requirements and industry standards.
