antlr/grammars-v4 - Grammars written for ANTLR v4 expectation that the grammars are free of actions.I don’t see how this can help me to ensure compliance, sorry.A curated list of my GitHub stars! Generated by starred. You (or an attacker on the machine) can send inventory and compliance data not just in its name. But it is not restricted to a specific instance. The first statement allows your EC2 instance to report data to SSM. Remember, you attached the managed policy to your EC2 instance to allow the SSM agent to talk to the AWS API.

Let’s look at the AmazonEC2RoleforSSM policy statements in more details. Protect yourself: limit permissions of the SSM agent It’s unlikely that you can separate the permission properly in the same AWS account. You also have to ensure that tagging is restricted! Otherwise, the tag-based restriction is pointless.Īssuming that multiple workloads run in the same account and you want to restrict access to only some engineers I highly recommend to put each workload in a separate AWS account. If you still want to use SSM, I recommend that you allow ssm:SendCommand and ssm:StartSession only for specific tags using permissions. It is unclear whether it is possible to restrict all of the actions to certain EC2 instances. Unfortunately, the documentation of the resource-level permissions and conditions is incomplete.

ssm:RegisterTargetWithMaintenanceWindowįine, so we need to restrict access to these actions to certain EC2 instances only.

You have to be very careful about the following permissions which can be used to execute a command on an EC2 instance via the SSM agent: Thanks to AmazonEC2RoleforSSM you can now read all the data from S3, or do you prefer to override some data stored on S3, or you might want to inject some nonsense logs? No problem. Even better, all commands that are executed use the permissions of the EC2 instance where it runs on. You can now use SSM Run Commands or Session Manager to execute any command on any EC2 instance as root. Very likely, you have those permissions thanks to managed policies like AdministratorAccess, PowerUserAccess, or AmazonSSMFullAccess.

To use SSM, your IAM user or role also needs permissions.

The docs suggest that you attach the managed policy AmazonEC2RoleforSSM to your IAM instance (using an IAM instance profile with an IAM role).

You also have to grant your EC2 instances permissions to talk to the SSM API.

Amazon Linux 2 comes with the SSM agent pre-installed and pre-started.

OSQUERY KILLS EC2 INSTALL

To use SSM, you have to install the SSM agent on your EC2 instances.

OSQUERY KILLS EC2 PATCH

SSM is a handy service to replace SSH, patch your OS, and much more.

The three steps to enable the trojan horse: One team member nailed it: we installed a trojan horse! Read on to understand how the backdoor works and how you can close it. On top of it, they granted full read and write permissions to every S3 bucket and full write access to CloudWatch Logs. What the team didn’t know: they enabled a backdoor that allows everyone with access to the AWS account to run commands on every EC2 instance as root. At some point, the team demonstrated how they use AWS Systems Manager (SSM) to run commands on a machine. Recently, I held a security workshop together with a team of engineers.
