This post discusses an automated process for enabling Amazon Virtual Private Cloud (Amazon VPC) Flow Logs using AWS Config rule remediation. Customers use Amazon VPC Flow logs to capture information about the IP traffic going to and from network interfaces in an Amazon VPC. You can deploy this solution with the help of AWS Control […]Read More
Automate time series network visualizations for AWS PrivateLink using Amazon CloudWatch Contributor Insights
AWS PrivateLink is a highly available, scalable technology that lets you connect your Amazon Virtual Private Cloud (VPC) to supported AWS services without requiring public internet traversal. It also lets you privately connect to services hosted by other AWS accounts (VPC endpoint services) and supported AWS Marketplace partner services. Amazon CloudWatch Contributor Insights is a […]Read More
In a previous blog post, we provided a walkthrough of how to fix unreachable Amazon EC2 Windows instances using the EC2Rescue for Windows tool. In this blog post, I will walk you through how to utilize EC2Rescue for Linux to fix unreachable Linux instances. This Knowledge Center Article describes how EC2Rescue for Linux can be used to […]Read More
On-Demand Capacity Reservations enable you to reserve capacity for Amazon Elastic Compute Cloud(Amazon EC2) instances in an Availability Zone for any duration. You can use AWS Resource Groups to organize AWS resources into logical collections of applications, projects or environments. Last year, we introduced the ability to target EC2 capacity reservations in a resource group by using […]Read More
One of the first tasks my customers do when creating a new AWS account is to create the right network integration for their enterprise. Typically, this means implementing an Amazon Virtual Private Cloud (VPC) across a multi-account framework that was provisioned with AWS Control Tower. When these are provisioned in a self-service model, we see […]Read More
Using AWS Cost and Usage Reports and Cost Allocation Tags to understand VPC Flow Logs data ingestion costs in Amazon S3
AWS customers enable the VPC Flow Logs feature in their accounts for security, governance, and auditing. They often have several teams who create VPC flow log subscriptions for their workloads and publish the data to the same Amazon Simple Storage Service (Amazon S3) bucket as part of a centralized logging architecture. Customers need a way […]Read More
You can use rules in Amazon CloudWatch Contributor Insights to gain security visibility into your VPC flow logs. The rules analyze flow logs in targeted groups in Amazon CloudWatch Logs and display the Top-N contributors for a given log field or combination of log fields. In this post, I’ll show you how to set up CloudWatch Contributor Insight rules for VPC flow logs. I’ll demonstrate how to:
Map the VPC flow log format to rules in Contributor Insights.
Explain how a single rule can be used to monitor many VPC flow logs.
Walk through some sample rules and show them in a CloudWatch dashboard.
Session Manager is a fully managed AWS Systems Manager capability that you can use to manage your Amazon Elastic Compute Cloud (Amazon EC2) instances, on-premises instances, and virtual machines (VMs) through an interactive one-click browser-based shell or through the AWS CLI. Session Manager also provides secure and auditable instance management without the need to open […]Read More
Port forwarding is a useful way to redirect network traffic from one IP address and port number combination to another. With port forwarding, you can access an EC2 instance located in a private subnet from your workstation. In this post, we walk through a use case where customers have a strict security requirement for their […]Read More
Introduction Many of the customers that we have worked with are using advanced network architectures in AWS for multi-VPC and multi-account architectures. Placing workloads into separate Amazon Virtual Private Clouds (VPCs) has several advantages, chief among them isolating sensitive workloads and allowing teams to innovate without fear of impacting other systems. Many companies are taking […]Read More
