When creating an ECS instance of the VPC network, you can either use the default security group or use other existing security groups in the VPC. A security group is a virtual firewall used to control the inbound and outbound traffic of an ECS instance.
This topic lists some common security group configurations for ECS instances of the VPC network.
This document introduces how to implement data security for ECS instances from the O&M perspective.
When you create an Alibaba Cloud Elastic Compute Service (ECS) instance, you also create or specify a security group. This security group acts as a firewall controlling what can access your ECS instance. For Linux instances, one of the rules allows SSH (TCP port 22) access. Best practices require that you only allow SSH access from TCP/IP addresses that you control. By only allowing your TCP/IP addresses through the security group (firewall) you reduce the exposure footprint of your ECS instance.
Creating a security group rule for SSH is very easy on the Alibaba Cloud Console. However, keeping that rule up to date with your current TCP/IP address can be a pain. First you must figure out what your public TCP/IP address is, login to the Alibaba Cloud Console, find your security group and then modify the security group with a new rule for your public IP address and finally delete the old rule.
In this tutorial, we will learn how to use Windows Task Scheduler to setup a recurring task to automatically keep your ECS security group up to date with your public TCP/IP address.
In this article, we will address these concerns by discussing the top 5 security considerations you should look out for in a cloud provider. The Alibaba Cloud Security team has also written a detailed security whitepaper, covering all your security concerns of deploying on Alibaba Cloud.
Alibaba Cloud Elastic Compute Service (ECS) provides fast memory and the latest Intel CPUs to help you to power your cloud applications and achieve faster results with low latency. All ECS instances come with Anti-DDoS protection to secure your data and applications from DDoS and Trojan attacks.
