Summary

Having a good logging strategy for your AWS Services is a recommended best practice in every case. It increases operational visibility and strengthens an enterprise's security posture in a measurable manner.

It is recommended, but it is not always easy to set up, and it is rarely done for you.

A good logging strategy for AWS services should utilize the most cost effective, secure, and reliable solutions available, and include data analysis that can yield actionable intelligence.

• This will mean storing logs in S3, typically with secure encryption and versioning enabled, as well as Cfn Retention set.
• Creating a secure Glue Database for storage and analysis of log data
• Writing custom Glue jobs that can extract and transform logs from S3, and store them in the Glue database
• Writing Athena queries tuned for that particular service's log data, that can produce good information, and saving them as named queries

The AwsLoggingStack sets that up for seven of the AWS services where it is most frequently needed, handling everything from bucket to query for:

• Application Load Balancer
• CloudFront
• CloudTrail
• VPC FlowLogs
• S3(Access Logs)
• SES
• WAF

S3 Access logging is enabled for all the logging buckets, with logs delivered to the S3AccessLogsBucket.

Usage

All S3 buckets, Glue resources, and Athena queries are created using cdk_extensions modules. As such, this stack can be initialized with no parameters to rapidly deploy an industry standard logging strategy into an AWS account, including recommended named Athena Queries for each service.

Install

To import and use this module within your CDK project:

TypeScript

import { AwsLoggingStack } from 'cdk-extensions/stacks';

new AwsLoggingStack(this, 'AwsLoggingStack')

Python

from cdk_extensions.stacks import (
AwsLoggingStack
)

aws_logging_stack = AwsLoggingStack(self, 'AwsLoggingStack')

Enable Logging

AwsLoggingStack manages buckets, glue tables, and permissions. All that is left is to start delivering the logs.

Remember that logging configuration for most aws-cdk-lib constructs will require an L2 construct(i.e. iBucket), but the resources created by the AwsLoggingStack are L1 constructs(i.e. CfnBucket). In order to configure cdk-extensions logging buckets, they must be first wrapped in an L2 construct.

logging_stack = new AwsLoggingStack(this, 'LoggingStack')

const l2_cloudtrail_bucket = s3.Bucket.fromCfnBucket(
  logging_stack.cloudtraillogsBucket.resource
);

const trail = new cloudtrail.Trail(this, 'myCloudTrail', {
  bucket: l2_cloudtrail_bucket
});

Follow the docs for each service or resource to enable logging to the respective AwsLoggingStack S3 buckets:

• Enable Logging on an ALB

• Enable Logging on a CloudFront Distribution

• Create A Trail on CloudTrail

• Publish VPC Flow Logs to S3

• Enable Server Access logging for S3 Access Logs

• Stream SES Event logs

• As described in the documentation linked above, SES event logs first need to publish to an intermediate service, such as Kinesis Firehose, and then be streamed to the S3 bucket(opinionated Firehose constructs are also available in cdk-extensions/kinesis-firehose)

  • Enable WAF logging to S3

  The Athena Queries

  Once beyond the nuts and bolts of setting up logging buckets and glue jobs to get important data into a secure format that can be queried, your data provides its best value through well written Athena queries that draw out important metrics and actionable intelligence. The AwsLoggingStack creates a few immediately useful CfnNamedQueries for each service to get you started.

  Application Load Balancer

  Two Athena queries provide valuable insight into traffic to your ALB:

  • alb-top-ips: Gets the 100 most active IP addresses by request count.
  • alb-5xx-errors: Gets the 100 most recent ELB 5XX responses

  CloudFront Distribution

  Four Athena queries provide valuable insight into traffic across your CDNs.

  • cloudfront-distribution-statistics: Gets statistics for CloudFront distributions for the last day.
  • cloudfront-request-errors: Gets the 100 most recent requests that resulted in an error from CloudFront.
  • cloudfront-top-ips: Gets the 100 most active IP addresses by request count.
  • cloudfront-top-objects: Gets the 100 most requested CloudFront objects.

  CloudTrail

  Two Athena queries provide valuable insight into user activity on your AWS account.

  • cloudtrail-unauthorized-errors: Gets the 100 most recent unauthorized AWS API calls.
  • cloudtrail-user-logins: Gets the 100 most recent AWS user logins.

  VPC FlowLogs

  An Athena query is created to expose info about rejected internal traffic

  • flow-logs-internal-rejected: Gets the 100 most recent rejected packets that stayed within the private network ranges.

  S3 Access Logs

  An Athena query is created that exposes failed attempts to access your S3 buckets

  • s3-request-errors: Gets the 100 most recent failed S3 access requests.

  SES

  Protect your domain, and your enterprise's, sending reputation by tracking bounces and complaints

  • ses-bounces: Gets the 100 most recent bounces from the last day.
  • ses-complaints: Gets the 100 most recent complaints from the last day.

  WAF

  Strategy is implemented for storage of WAF logs in S3 with ETL jobs loading to the Glue table, but no default Athena queries have been added yet.

  More Info About The Resources

  This solution utilizes the AwsLoggingStack patterns from the cdk-extensions/glue-tables and cdk-extensions/s3-buckets libraries, which in turn utilize constructs from cdk-extensions Glue and Athena libraries. Detailed info about each is covered their respective documentation.

Functions

func AwsLoggingStack_IsConstruct

func AwsLoggingStack_IsConstruct(x interface{}) *bool

Checks if `x` is a construct.

Returns: true if `x` is an object created from a class which extends `Construct`. Deprecated: use `x instanceof Construct` instead.

func AwsLoggingStack_IsStack

func AwsLoggingStack_IsStack(x interface{}) *bool

Return whether the given object is a Stack.

We do attribute detection since we can't reliably use 'instanceof'.

func AwsLoggingStack_Of

func AwsLoggingStack_Of(construct constructs.IConstruct) awscdk.Stack

Looks up the first stack scope in which `construct` is defined.

Fails if there is no stack up the tree.

func NewAwsLoggingStack_Override

func NewAwsLoggingStack_Override(a AwsLoggingStack, scope constructs.Construct, id *string, props *AwsLoggingStackProps)

Creates a new instance of the AwsLoggingStack class.

Types

	//     "human"      "hash"
	//
	// If the "human" part of the ID exceeds 240 characters, we simply trim it so
	// the total ID doesn't exceed CloudFormation's 255 character limit.
	//
	// We only take 8 characters from the md5 hash (0.000005 chance of collision).
	//
	// Special cases:
	//
	// - If the path only contains a single component (i.e. it's a top-level
	//   resource), we won't add the hash to it. The hash is not needed for
	//   disambiguation and also, it allows for a more straightforward migration an
	//   existing CloudFormation template to a CDK stack without logical ID changes
	//   (or renames).
	// - For aesthetic reasons, if the last components of the path are the same
	//   (i.e. `L1/L2/Pipeline/Pipeline`), they will be de-duplicated to make the
	//   resulting human portion of the ID more pleasing: `L1L2Pipeline<HASH>`
	//   instead of `L1L2PipelinePipeline<HASH>`
	// - If a component is named "Default" it will be omitted from the path. This
	//   allows refactoring higher level abstractions around constructs without affecting
	//   the IDs of already deployed resources.
	// - If a component is named "Resource" it will be omitted from the user-visible
	//   path, but included in the hash. This reduces visual noise in the human readable
	//   part of the identifier.

	// the resource and the manual export.
	//
	// ## Example
	//
	// Here is how the process works. Let's say there are two stacks,
	// `producerStack` and `consumerStack`, and `producerStack` has a bucket
	// called `bucket`, which is referenced by `consumerStack` (perhaps because
	// an AWS Lambda Function writes into it, or something like that).
	//
	// It is not safe to remove `producerStack.bucket` because as the bucket is being
	// deleted, `consumerStack` might still be using it.
	//
	// Instead, the process takes two deployments:
	//
	// ### Deployment 1: break the relationship
	//
	// - Make sure `consumerStack` no longer references `bucket.bucketName` (maybe the consumer
	//   stack now uses its own bucket, or it writes to an AWS DynamoDB table, or maybe you just
	//   remove the Lambda Function altogether).
	// - In the `ProducerStack` class, call `this.exportValue(this.bucket.bucketName)`. This
	//   will make sure the CloudFormation Export continues to exist while the relationship
	//   between the two stacks is being broken.
	// - Deploy (this will effectively only change the `consumerStack`, but it's safe to deploy both).
	//
	// ### Deployment 2: remove the bucket resource
	//
	// - You are now free to remove the `bucket` resource from `producerStack`.
	// - Don't forget to remove the `exportValue()` call as well.
	// - Deploy again (this time only the `producerStack` will be changed -- the bucket will be deleted).

	//
	// The ARN will be formatted as follows:

Creates a Stack that deploys a logging strategy for several AWS services.

Stack creates a Glue Database using cdk-extensions Database, deploys cdk-extensions/s3-buckets patterns for each service, and utilizes methods exposed by cdk-extensions/s3-buckets S3AccessLogsBucket to enable logging for each created bucket. See: {@link aws-s3-buckets!WafLogsBucket | cdk-extensions/s3-buckets WafLogsBucket}
