AWS GuardDuty Reviews

We mainly use AWS GuardDuty to detect compromised EC2 instances. Primarily, we use it to identify suspicious activity, such as unusual outbound traffic, connections to known malicious IP addresses, or unauthorized attempts to access EC2 instances. This may indicate a compromised instance. 

Additionally, we use GuardDuty to monitor S3 bucket misconfigurations and for threat detection on Lambda functions. We analyze cloud logs for suspicious API calls and abnormal execution patterns within AWS Lambda functions, helping us identify potential misuse. 

Another use case is that we use GuardDuty to detect credential stuffing attacks by identifying failed login attempts, particularly from unusual locations or at high frequency, indicating potential credential stuffing attacks or brute force attempts. 

Furthermore, GuardDuty can also monitor for large-scale data downloads or uploads, potentially indicating data exfiltration attempts by unauthorized actors or malware.

GuardDuty's automated incident response feature allows us to integrate it with Lambda and CloudWatch to trigger automated responses. This enables quick actions such as disabling AWS IAM users, blocking malicious IPs, or isolating compromised EC2 instances.

The main use cases of GuardDuty, when combined with AWS Security, are to offer in-depth security issue detection, such as identifying brute force attacks or unauthorized SSH attempts into your infrastructure, as well as other anomalous behaviors. GuardDuty serves as a threat detection and intelligence service.

GuardDuty is extensive in terms of configuration and security compliance. It integrates with threat detection, offering end-to-end visibility. The best thing is that it notifies you immediately when something goes wrong, allowing quick response to threats. Our infrastructure is continuously monitored, safeguarding it against threats. Even internal threats are easy to identify. AWS monitors user behavior, which helps detect compromised credentials.

We leverage the solution to block anything malicious since it's a threat detection service. GuardDuty allows us to monitor accounts in a much better way. The solution looks for any malicious activity that's going on and will notify you if anything is going on with your AWS accounts. It's not necessarily an IPS because it only alerts you about malicious activity.

The way it monitors accounts is definitely a very important feature. GuardDuty is a threat detection service. The solution looks for any kind of malicious activity or any unauthorized behavior that could breach some problems with accounts. GuardDuty does not just focus on AWS accounts but also on container applications and even Amazon S3 buckets. GuardDuty covers a range of different Amazon resources as part of the protection.

GuardDuty is predominantly used to find anomalies, particularly security anomalies when trying to probe a hosted public cloud service. For example, we work with Zuora, and have many public services running at AWS, and our concern is external parties. So, if a hacker or an attacker tries to probe our systems, Amazon GuardDuty tries to find anomalies or any vulnerabilities within our systems.

GuardDuty takes multiple sources of logs. In AWS, we have several logging services like AWS CloudTrail and VPC Flow Logs. VPC Flow Logs involve incoming and outgoing traffic from the internet, so if someone tries to get into a system or access one of our publicly hosted AWS, we are able to get that traffic via VPC Flow Logs. AWS CloudTrail is within the public cloud infrastructure, and AWS-specific API calls are involved. So, if someone tries to do some API activity specific to AWS within the infrastructure, this will be a source. These are multiple sources of logs that Amazon GuardDuty consumes as input to analyze the traffic for any security anomalies. So, based on these sources, the solution helps us report findings if security anomalies occur in our systems from the internet or within the cloud infra, cloud account, or AWS account.

AWS is account-specific, and last year, I believe AWS included something related to Kubernetes monitoring or Kubernetes Logs. So if we use EKS within the Kubernetes service and an anomaly occurs, some anomaly traffic is seen in the Kubernetes cluster, and it will be able to identify. That is a good feature they recently added in testable APIs.

Protect your accounts, data, and assets across diverse AWS computing environments, encompassing Amazon Elastic Compute Cloud (Amazon EC2), serverless operations, and container workloads, including those utilizing AWS Fargate.

AWS GuardDuty enhances organizational security by providing automated threat detection, easy integration with other AWS services, centralized monitoring of security findings, cost-effective security, and scalability. 

AWS initially interested me more from the architecture and direction perspective, rather than DevOps, for instance. I wanted to gain expertise in the wide range of services they offer, one of which is GuardDuty. It's not my main focus, but it's a good basic threat detection starting point. 

Whenever we need some kind of service for threat detection, we go to one of the many options in the vast AWS cloud portfolio. We pick GuardDuty to protect our endpoints, and it's a good first-line solution for quick deployment. 

Once we have experience using this AWS offering, we'll likely start looking deeper. We might then go to the marketplace to find another, potentially third-party solution. 

I mainly use GuardDuty to check user responses, collect logs, and collect data on who logs in and out and their permission and authorization. 

Prior to using GuardDuty, we had multiple systems to collect data and put it in a centralized location so we could look into it. Now we don't need to do that anymore as GuardDuty does it for us.

I use AWS GuardDuty to identify, detect, and mitigate any threats within the organization.

The solution provides AWS GuardDuty S3 protection, EKS runtime protection, and malware protection.
