AWS Inspector vs Guardduty

Both Amazon Inspector and Amazon GuardDuty are services that enhance your cloud security posture. Both serve you through some form of automation — GuardDuty goes beyond automation and incorporates machine learning.

Amazon Inspector

It is a security assessment service provided by AWS that analyzes an organization’s Amazon Elastic Compute Cloud (EC2) instances and applications to identify vulnerabilities and potential security issues. It uses a variety of automated security assessments, including checking for missing security patches, weak credentials, and misconfigured security groups, to identify potential security risks and provide a detailed report of the findings, including recommendations for remediation. Some of the features of Amazon Inspector include:

• Automated security assessments: Inspector performs automated security assessments by conducting a variety of tests, including checking for missing security patches, weak credentials, and misconfigured security groups.

• Detailed reports: Inspector provides a detailed report of the findings, including recommendations for remediation.

• Agentless: Inspector doesn’t require any agent to be installed on the instances, so it doesn’t affect the performance of the instances or the application.

• Network-level and host-level security assessments: Inspector can perform both network-level and host-level security assessments, providing a comprehensive view of the security posture of an organization’s EC2 instances and applications.

• Built-in security rules: Inspector includes a library of built-in security rules and the ability to create custom rules to suit specific needs.

• Multi-platform support: Inspector supports a wide range of platforms, including Windows, Linux, and Amazon Linux.
