Amazon GuardDuty is a machine studying (ML)-based safety monitoring and clever menace detection service that analyzes and processes varied AWS information sources, constantly displays your AWS accounts and workloads for malicious exercise, and delivers detailed safety findings for visibility and remediation.
I like the function of GuardDuty Runtime Monitoring that analyzes working system (OS)-level, community, and file occasions to detect potential runtime threats for particular AWS workloads in your setting. I first launched the final availability of this function for Amazon Elastic Kubernetes Service (Amazon EKS) sources in March 2023. Seb wrote in regards to the enlargement of the Runtime Monitoring function to offer menace detection for Amazon Elastic Container Service (Amazon ECS) and AWS Fargate in addition to the preview for Amazon Elastic Compute Cloud (Amazon EC2) workloads in Nov 2023.
Today, we’re asserting the final availability of Amazon GuardDuty EC2 Runtime Monitoring to develop menace detection protection for EC2 cases at runtime and complement the anomaly detection that GuardDuty already gives by constantly monitoring VPC Flow Logs, DNS question logs, and AWS CloudPath administration occasions. You now have visibility into on-host, OS-level actions and container-level context into detected threats.
With GuardDuty EC2 Runtime Monitoring, you may determine and reply to potential threats which may goal the compute sources inside your EC2 workloads. Threats to EC2 workloads usually contain distant code execution that results in the obtain and execution of malware. This might embrace cases or self-managed containers in your AWS setting which might be connecting to IP addresses related to cryptocurrency-related exercise or to malware command-and-control associated IP addresses.
GuardDuty Runtime Monitoring gives visibility into suspicious instructions that contain malicious file downloads and execution throughout every step, which will help you uncover threats throughout preliminary compromise and earlier than they develop into business-impacting occasions. You also can centrally allow runtime menace detection protection for accounts and workloads throughout the group utilizing AWS Organizations to simplify your safety protection.
Configure EC2 Runtime Monitoring in GuardDuty
With just a few clicks, you may allow GuardDuty EC2 Runtime Monitoring within the GuardDuty console. For your first use, you could allow Runtime Monitoring.
Any prospects which might be new to the EC2 Runtime Monitoring function can strive it for free for 30 days and achieve entry to all options and detection findings. The GuardDuty console reveals what number of days are left within the free trial.
Now, you may arrange the GuardDuty safety agent for the person EC2 cases for which you need to monitor the runtime habits. You can select to deploy the GuardDuty safety agent both routinely or manually. At GA, you may allow Automated agent configuration, which is a most popular choice for many prospects because it permits GuardDuty to handle the safety agent on their behalf.
The agent might be deployed on EC2 cases with AWS Systems Manager and makes use of an Amazon Virtual Private Cloud (Amazon VPC) endpoint to obtain the runtime occasions related along with your useful resource. If you need to handle the GuardDuty safety agent manually, go to Managing the safety agent Amazon EC2 occasion manually within the AWS documentation. In multiple-account environments, delegated GuardDuty administrator accounts handle their member accounts utilizing AWS Organizations. For extra data, go to Managing a number of accounts within the AWS documentation.
When you allow EC2 Runtime Monitoring, you could find the coated EC2 cases record, account ID, and protection standing, and whether or not the agent is ready to obtain runtime occasions from the corresponding useful resource within the EC2 occasion runtime protection tab.
Even when the protection standing is Unhealthy, which means it isn’t presently capable of obtain runtime findings, you continue to have protection in depth on your EC2 occasion. GuardDuty continues to offer menace detection to the EC2 occasion by monitoring CloudPath, VPC movement, and DNS logs related to it.
Check out GuardDuty EC2 Runtime safety findings
When GuardDuty detects a possible menace and generates safety findings, you may view the small print of the wholesome data.
Choose Findings within the left pane if you wish to discover safety findings particular to Amazon EC2 sources. You can use the filter bar to filter the findings desk by particular standards, corresponding to a Resource kind of Instance. The severity and particulars of the findings differ primarily based on the useful resource function, which signifies whether or not the EC2 useful resource was the goal of suspicious exercise or the actor performing the exercise.
With right now’s launch, we help over 30 runtime safety findings for EC2 cases, corresponding to detecting abused domains, backdoors, cryptocurrency-related exercise, and unauthorized communications. For the total record, go to Runtime Monitoring discovering sorts within the AWS documentation.
Resolve your EC2 safety findings
Choose every EC2 safety discovering to know extra particulars. You can discover all the data related to the discovering and look at the useful resource in query to find out whether it is behaving in an anticipated method.
If the exercise is permitted, you should utilize suppression guidelines or trusted IP lists to forestall false optimistic notifications for that useful resource. If the exercise is sudden, the safety finest observe is to imagine the occasion has been compromised and take the actions detailed in Remediating a doubtlessly compromised Amazon EC2 occasion within the AWS documentation.
You can combine GuardDuty EC2 Runtime Monitoring with different AWS safety providers, corresponding to AWS Security Hub or Amazon Detective. Or you should utilize Amazon EventBridge, permitting you to make use of integrations with safety occasion administration or workflow programs, corresponding to Splunk, Jira, and ServiceNow, or set off automated and semi-automated responses corresponding to isolating a workload for investigation.
When you select Investigate with Detective, you could find Detective-created visualizations for AWS sources to rapidly and simply examine safety points. To be taught extra, go to Integration with Amazon Detective within the AWS documentation.
Things to know
GuardDuty EC2 Runtime Monitoring help is now obtainable for EC2 cases working Amazon Linux 2 or Amazon Linux 2023. You have the choice to configure most CPU and reminiscence limits for the agent. To be taught extra and for future updates, go to Prerequisites for Amazon EC2 occasion help within the AWS documentation.
To estimate the day by day common utilization prices for GuardDuty, select Usage within the left pane. During the 30-day free trial interval, you may estimate what your prices might be after the trial interval. At the tip of the trial interval, we cost you per vCPU hours tracked month-to-month for the monitoring brokers. To be taught extra, go to the Amazon GuardDuty pricing web page.
Enabling EC2 Runtime Monitoring additionally permits for a cost-saving alternative in your GuardDuty value. When the function is enabled, you gained’t be charged for GuardDuty foundational safety VPC Flow Logs sourced from the EC2 cases working the safety agent. This is because of comparable, however extra contextual, community information obtainable from the safety agent. Additionally, GuardDuty would nonetheless course of VPC Flow Logs and generate related findings so you’ll proceed to get network-level safety protection even when the agent experiences downtime.
Now obtainable
Amazon GuardDuty EC2 Runtime Monitoring is now obtainable in all AWS Regions the place GuardDuty is offered, excluding AWS GovCloud (US) Regions and AWS China Regions. For a full record of Regions the place EC2 Runtime Monitoring is offered, go to Region-specific function availability.
Give GuardDuty EC2 Runtime Monitoring a strive within the GuardDuty console. For extra data, go to the Amazon GuardDuty User Guide and ship suggestions to AWS re:Post for Amazon GuardDuty or by way of your regular AWS help contacts.
