What is AWS Config? How to use and introduce points that dramatically improve security operations

In this article, we will explain how AWS Config supports security operations and greatly reduces the burden.

"AWS security operations are difficult and tired"
"Is there a way to make it more efficient?"
If so, please read to the end!

**What is AWS Config? **

AWS Config is a managed service provided by AWS that records, audits, and evaluates configuration changes to cloud resources.

Key Features

• Record configuration changes for resources
  *Resources to be recorded may need to be explicitly set
• Detect misconfigurations and policy violations
• Historical management of past configuration states
• Real-time and continuous compliance assessment

Note: AWS Config itself does not have threat detection capabilities (e.g., suspicious communications, etc.).
It can be used in conjunction with GuardDuty and other devices to enhance security.

**Why Do You Need AWS Config? **

For example, if one day suddenly your S3 bucket is publicly accessible...
If you don't notice the change, there is a risk of information leakage.

AWS Config

• Record who, when, and what changes were made
• Automatic detection of policy violations (e.g., encryption leakage in S3 buckets)
• Troubleshooting based on past configuration status is possible

What AWS Config Can Do

1. Real-Time Configuration Monitoring

Instantly record and visualize configuration changes for target resources.

2. Automated Compliance Assessment

AWS Config Rules automatically evaluates whether the settings are in line with the policy.

3. Troubleshooting with History Review

You can check back on past resource configurations.

4. Proactive Evaluation

The ability to pre-evaluate whether or not a new resource is compliant before creating it.

**When combined with Colorkrew's SOC services? **

Operations that cannot be completed by AWS Config alone can be further enhanced by linking with our SOC services.

Benefits of Combinations

• Analyze and prioritize Config alerts
• Integrated analytics with threat detection services such as GuardDuty
• Support for the implementation of automatic remediation in conjunction with AWS Lambda
• Providing know-how and tools to optimize security operations

**Consider Implementing It? **

At our company,

• AWS Config Implementation Support
• Designed to work with AWS Lambda
• 24/365 monitoring support by SOC

We provide full-stack security operation support.
