Looking to lock down your AWS cloud service? Here are the 10 steps to take for AWS security
As more companies embrace the cloud, security is becoming a more significant challenge. Irrespective of size, organizations are increasingly realizing the importance of having proper cloud security practices in place. More and more companies are creating a culture where digital engineering teams are making cloud security a priority and checking whether their service providers can provide the correct security levels for their cloud workload. It is up to organizations, in partnership with their cloud service providers, to understand the different security roles, responsibilities, tools and best practices.
It turns out that getting the balance right security-wise is becoming easier. For example, AWS has published its cloud security best practices to help customers implement cloud services in a highly secure manner. These best practices provide guidance to organizations unsure of the tools or services they require. The AWS cloud platform allows customers to scale and innovate while maintaining a secure environment; customers only pay for the cloud security services they are using without any upfront expenses, unlike the on-premises environments.
When it comes to cloud security SNAFUs, misconfigurations that accidentally and unnecessarily expose services are the biggest culprits. Any misconfigurations during implementation can potentially lead to big problems down the road. In the cloud, resource provisioning, management and monitoring happen via APIs, consoles and command-line interfaces (CLIs). So, it’s essential to secure all these connections during the early stage of cloud adoption.
Teams also must ensure that virtualization, identity and access management (IAM), workload protection and network security and encryption are a part of this architecture blueprint. We are all familiar with catastrophic data breaches that make the news, but there are many others that do not, and the vast majority of these are avoidable. Let’s examine the following three scenarios, all derived from real experiences, and then look at how the vulnerability could have been avoided.
An AWS account was compromised due to a weak root user password, combined with MFA not being configured. An attacker removed EBS, EC2 instances, S3 data backup and asked for a ransom to provide the database backup file.
This could have been prevented by utilizing an IAM user with a specific policy instead of using the root account.
The developer posted the development account credentials for the AWS access and secret access key in the script, which was on the public Git repository. Using those keys enabled the attackers to deploy multiple resources in all regions and created multiple dummy resources. For the six to eight hours that the account was hijacked, the attackers racked up a bill of $4,000 to $5,000.
This could have been prevented by using an IAM role instead of hard-coding the access keys into code. Access keys should be rotated periodically.
The security group was not properly configured. In particular, port 22 was allowed globally, ports 80 and 443 were also open from all. The application which was hosted on EC2 instance was front-ended by the application load balancer. The attackers found a basic cross-site scripting vulnerability and SQL injection, tried injecting malicious scripts and removed all the data from the server.
This could have been prevented by following a trusted advisory, putting WAF on top of the application load balancer and utilizing the AWS inspector for security assessments.
These three cautionary tales are all examples of where a small security vulnerability caused big losses, and they all demonstrate how easy it would have been to deploy the secure cloud option. Hindsight is a wonderful thing, but it is even better to avoid making the error in the first place. Here is a 10-step guide to understanding security best practice structures and how users should implement the AWS platform and its services in the best way.
Implementing these cloud security best practices guidelines provided by AWS helps organizations implement the proper security measures, irrespective of where they are in their digital transformation journey or how large their organization is.
