You can monitor application security for Ruby apps running in Docker, Kubernetes, Amazon ECS, and AWS Fargate.

사전 필수 조건

1-클릭 활성화
서비스가 원격 구성이 활성화된 Agent와 이를 지원하는 추적 라이브러리 버전으로 실행 중인 경우 ASM 상태 열의 Not Enabled 표시 위로 마우스를 가져간 다음 Enable ASM를 클릭합니다. DD_APPSEC_ENABLED=true 또는 --enable-appsec 플래그를 사용하여 서비스를 다시 시작할 필요가 없습니다.

Enabling threat detection

Get started

  1. Update your Gemfile to include the Datadog library:

    gem 'datadog', '~> 2.0' # Use 'ddtrace' if you're using v1.x

    To check that your service’s language and framework versions are supported for ASM capabilities, see Compatibility.

    For more information about upgrading to v2 from a dd-trace 1.x version, see the Ruby tracer upgrade guide.

  2. Enable ASM by enabling the APM tracer. The following options describe a quick setup that covers the most common cases. Read the Ruby tracer documentation for more details.

    You can enable ASM either in your code:

      Enable the APM tracer by adding an initializer in your application code:

      # config/initializers/datadog.rb

require 'datadog/appsec'

Datadog.configure do |c|
  # enable the APM tracer
  c.tracing.instrument :rails

  # enable ASM
  c.appsec.enabled = true
  c.appsec.instrument :rails
end

      Or enable the APM tracer through auto-instrumentation by updating your Gemfile to auto-instrument:

      gem 'datadog', '~> 2.0', require: 'datadog/auto_instrument'

      And also enable appsec:

      # config/initializers/datadog.rb

require 'datadog/appsec'

Datadog.configure do |c|
  # the APM tracer is enabled by auto-instrumentation

  # enable ASM
  c.appsec.enabled = true
  c.appsec.instrument :rails
end

      Enable the APM tracer by adding the following to your application’s startup:

      require 'sinatra'
require 'datadog'
require 'datadog/appsec'

Datadog.configure do |c|
  # enable the APM tracer
  c.tracing.instrument :sinatra

  # enable ASM for Sinatra
  c.appsec.enabled = true
  c.appsec.instrument :sinatra
end

      Or enable the APM tracer through auto-instrumentation:

      require 'sinatra'
require 'datadog/auto_instrument'

Datadog.configure do |c|
  # the APM tracer is enabled by auto-instrumentation

  # enable ASM for Sinatra
  c.appsec.enabled = true
  c.appsec.instrument :sinatra
end

      Enable the APM tracer by adding the following to your config.ru file:

      require 'datadog'
require 'datadog/appsec'

Datadog.configure do |c|
  # enable the APM tracer
  c.tracing.instrument :rack

  # enable ASM for Rack
  c.appsec.enabled = true
  c.appsec.instrument :rack
end

use Datadog::Tracing::Contrib::Rack::TraceMiddleware
use Datadog::AppSec::Contrib::Rack::RequestMiddleware

      Or one of the following methods, depending on where your application runs:

        Update your configuration container for APM by adding the following argument in your docker run command:

        docker run [...] -e DD_APPSEC_ENABLED=true [...]

        Add the following environment variable value to your container Dockerfile:

        ENV DD_APPSEC_ENABLED=true

        Update your configuration yaml file container for APM and add the AppSec env variable:

        spec:
  template:
    spec:
      containers:
        - name: <CONTAINER_NAME>
          image: <CONTAINER_IMAGE>/<TAG>
          env:
            - name: DD_APPSEC_ENABLED
              value: "true"

        Update your ECS task definition JSON file, by adding this in the environment section:

        "environment": [
  ...,
  {
    "name": "DD_APPSEC_ENABLED",
    "value": "true"
  }
]

        Initialize ASM in your code or set DD_APPSEC_ENABLED environment variable to true in your service invocation:

        env DD_APPSEC_ENABLED=true rails server

      라이브러리가 애플리케이션에서 보안 데이터를 수집해 에이전트로 전송하고, 이 데이터는 다시 Datadog로 전송됩니다. 그러면 기본 감지 규칙에 의해 공격자 기술과 잠재 구성 오류가 플래그되어 문제 해결을 위한 단계를 밟을 수 있습니다.

      1. 애플리케이션 보안 관리에서 감지 활동을 잘 하고 있는지 확인하려면 알려진 공격 패턴을 애플리케이션으로 보내세요. 예를 들어 다음 curl 스크립트가 포함된 파일을 실행해 보안 스캐너 감지됨 규칙을 트리거할 수 있습니다.

        for ((i=1;i<=250;i++)); 
        do
        # Target existing service’s routes
        curl https://your-application-url/existing-route -A dd-test-scanner-log;
        # Target non existing service’s routes
        curl https://your-application-url/non-existing-route -A dd-test-scanner-log;
        done

        참고: dd-test-scanner-log 값은 최신 릴리스에서 지원됩니다.

        애플리케이션을 활성화하고 실행한 몇 분 후 Datadog의 Application Trance and Signals Explorer에 위협 정보가 표시됩니다.
