**Setting Up Network Traffic Mirroring** 1. **Configure the Virtual Machine:** - Enable network traffic mirroring on the virtual machine's network interface. - Specify the destination for the mirrored traffic. 2. **Create a VPC Endpoint for Amazon Elastic File System (Amazon EFS):** - In the VPC where the virtual machine is located, create a VPC endpoint for Amazon EFS. - This endpoint will allow the virtual machine to access the NFS share on Amazon EFS. 3. **Create an NFS File System on Amazon EFS:** - Create an NFS file system that will store the mirrored traffic. - Mount the NFS file system on the virtual machine. 4. **Configure a Mirroring Session:** - In the Mirroring section of the AWS console, click "Create Mirroring Session". - Select the source network interface (the one attached to the virtual machine). - Select the destination (the NFS file system on Amazon EFS). **Accessing Mirrored Traffic** Once the mirroring session is established, all network traffic from the virtual machine will be mirrored to the NFS file system on Amazon EFS. You can access the mirrored traffic from the virtual machine by mounting the NFS file system. **Analyzing Mirrored Traffic** You can use any network traffic analysis tools (e.g., Wireshark) to analyze the mirrored traffic. To perform analysis on the virtual machine itself, you can use the following steps: 1. **Install a Network Analysis Tool:** - Install a network analysis tool such as Wireshark on the virtual machine. 2. **Capture Mirrored Traffic:** - Use the network analysis tool to capture the mirrored traffic. 3. **Analyze Traffic:** - Analyze the captured traffic to identify patterns, issues, or anomalies. **Additional Considerations:** - Mirrored traffic is written to Amazon EFS as raw packets. - The amount of mirrored traffic can be significant, so it's important to ensure adequate storage capacity on Amazon EFS. - The cost of mirroring traffic depends on the size of the packets and the duration of the mirroring session.

**Using AWS Network Load Balancer (NLB) to Mirror Traffic** **1. Create an NLB:** * In the AWS Management Console, navigate to Virtual Private Cloud (VPC) > Load Balancers. * Click "Create Load Balancer" and select "Network Load Balancer." * Configure basic settings, such as VPC, subnet, target group, and security group. **2. Enable Port Mirroring:** * In the NLB's configuration page, select "Listeners" and click "Add Listener." * Choose the protocol and port(s) for which you want to mirror traffic. * Under "Advanced Settings," check the "Enable Port Mirroring" checkbox. * Specify the destination VPC, subnet, and port where you want to send the mirrored traffic. **3. Create a VPC Endpoint for the Mirroring Target:** * In the VPC console, navigate to Endpoints > Create Endpoint. * Select the target VPC and subnet where you want to receive the mirrored traffic. * Choose "Interface Endpoint" as the type and "aws-load-balancer-listeners" as the service name. * Specify the name of the NLB and the port being mirrored. **4. Configure Virtual Machine Network Settings:** * On the virtual machine from which you want to read the traffic, ensure that the network adapter is attached to the subnet where the NLB's mirrored traffic is being received. * Configure the virtual machine's firewall to allow traffic from the NLB's mirrored traffic port. **5. Read Mirrored Traffic:** * Use a network packet analyzer or IDS/security tool configured to listen on the destination port specified in the NLB's port mirroring configuration. **Additional Notes:** * The virtual machine receiving the mirrored traffic will also receive other network traffic on the same subnet. Traffic filtering may be necessary. * NLB port mirroring only supports UDP and TCP traffic. * Mirrored traffic is not encrypted and may include sensitive data. Handle it securely.

**Step 1: Set up VPC Mirroring** * Enable VPC Mirroring in the VPC where your running services are located. * Create a Mirroring Destination: This is the target VPC where mirrored traffic will be sent. **Step 2: Create a Packet Broker** * Create a packet broker in the same region as your target VPC. * Configure the packet broker to: * Receive traffic from the mirroring destination * Decap the VXLAN tunnel encapsulating the mirrored traffic * Strip the headers to get the original IP packets **Step 3: Create a VPC Filter** * Create a VPC filter in the target VPC. * Configure the filter to: * Accept traffic from the packet broker * Match the criteria for the specific running services you want to monitor **Step 4: Setup Network Analyzer** * Create a Network Analyzer collector. * Configure the collector to: * Receive traffic from the VPC filter * Save the packets in a S3 bucket **Step 5: Inspect Traffic** * Use the Network Analyzer web interface or API to: * Visualize the network traffic * Set alerts and alarms based on traffic patterns * Analyze the traffic to troubleshoot issues and monitor service behavior **Services Used:** * VPC Mirroring * Packet Broker * VPC Filter * Network Analyzer

**Network Packet Broker (NPB)** **Purpose:** NPB is a managed service that allows you to inspect and analyze network traffic from EC2 instances, ECS containers, and VPC endpoints. **How to Use NPB to Mirror Traffic:** 1. **Configure NPB:** Create a Network Load Balancer (NLB) and configure it as an NPB analyzer. 2. **Set Up Flow Logs for Instances:** Configure CloudWatch Flow Logs on the target instances to send traffic logs to the NLB. 3. **Enable Network Insights:** Turn on Network Insights on the VPC and subnet where the instances are located. 4. **Associate NLB to VPC:** Associate the NLB (with NPB analyzer) with the VPC. 5. **Add Source Groups:** Create source groups for the instances or container groups you want to mirror traffic for. 6. **Create Mirror Sessions:** Create mirror sessions that associate the analyzer NLB with the source groups. This will automatically mirror traffic from the instances to the analyzer NLB. **Network Load Balancer (NLB)** **Purpose:** NLB can also be used as a traffic mirror without NPB, but it requires manual configuration and maintenance. **How to Use NLB to Mirror Traffic:** 1. **Create NLB:** Create an NLB in the VPC where the instances reside. 2. **Enable Flow Logs:** Enable flow logs for the NLB. 3. **Configure Target Groups:** Create target groups for the original instances and for the mirror hosts. 4. **Set Up Listeners:** Create listeners that route traffic to the original instance target group and to the mirror host target group simultaneously. 5. **Adjust Instance Security Groups:** Allow traffic from the NLB's MAC address to the target instances and mirror hosts. **Additional Considerations:** * Ensure that the instances and mirror hosts have enough CPU and memory resources to handle the mirrored traffic. * Use a dedicated VPC for the mirror hosts to prevent performance issues on other VPC workloads. * Monitor the traffic logs to ensure that mirroring is working correctly. * NPB provides additional features such as packet filtering, packet capture, and dashboards, which may be useful for advanced traffic analysis.

**Using AWS Traffic Mirroring to Monitor Network Traffic** **Step 1: Enable Network Interfaces for Traffic Mirroring** * Select the network interfaces (NICs) for the source and destination instances you want to mirror traffic between. * In the EC2 console, go to the "Network Interfaces" section. * Click "Actions" on the selected NICs and check "Enable Network Mirroring". **Step 2: Configure the Traffic Mirror Session** * Go to the "Network Mirroring" section in the EC2 console. * Click "Create Traffic Mirror Session". * Specify the following parameters: * **Source Interface:** The NIC that will send the mirrored traffic. * **Destination Interface:** The NIC that will receive the mirrored traffic. * **Instance Ports:** Optional, only mirror traffic for specific source/destination ports. * **ACL:** Optional, attach an Access Control List (ACL) to filter the mirrored traffic. * **Tags:** Metadata to help organize and identify the traffic mirror session. **Step 3: Create a Packet Forwarding Instance** * Launch an EC2 instance that will act as the packet forwarding instance. This instance will receive the mirrored traffic and forward it to the destination. * Create a security group that allows traffic on the ports you configured the traffic mirror session to mirror. **Step 4: Configure Packet Forwarding** * On the packet forwarding instance, install a traffic mirroring tool, such as tcpdump or Wireshark. * Configure the tool to listen on the interface that receives the mirrored traffic. * Set the destination IP address for the forwarded traffic to the destination instance or service. **Example:** Using tcpdump:
1 | tcpdump -i eth0 -w traffic.pcap |
