LambdaGuard

AWS Lambda is an event-driven, serverless computing platform provided by Amazon Web Services. It is a computing service that runs code in response to events and automatically manages the computing resources required by that code.

LambdaGuard is an AWS Lambda auditing tool designed to create asset visibility and provide actionable results. It provides a meaningful overview in terms of statistical analysis, AWS service dependencies and configuration checks from the security perspective.

Requirements

• Python 3.6.3+
• Java 8+ (optional for SonarQube)

Install

From PyPI

pip3 install lambdaguard

From Github

git clone https://github.com/Skyscanner/lambdaguard
cd lambdaguard
sudo make install

AWS Access

You will need a set of AWS access keys and permissions to run LambdaGuard.

make aws

Create a profile in ~/.aws/credentials with the newly created keys.

[LambdaGuardProfile]
aws_access_key_id = ...
aws_secret_access_key = ...

Alternatively, you can use the keys directly as CLI arguments (not recommended).

Run

• lambdaguard --help
• lambdaguard --function arn:aws:lambda:function
• lambdaguard --input function-arns.txt
• lambdaguard --output /tmp/lambdaguard
• lambdaguard --profile LambdaGuardProfile
• lambdaguard --keys ACCESS_KEY_ID SECRET_ACCESS_KEY
• lambdaguard --region eu-west-1
• lambdaguard --verbose

SonarQube: Static Code Analysis

Build SonarQube

• make sonarqube

Use SonarQube

• lambdaguard --sonarqube config.json

Config should have the following format:

{
    "command": "java -jar /opt/sonar-scanner-cli.jar -X",
    "url": "http://localhost:9000",
    "login": "admin",
    "password": "admin"
}

Development

make -B clean
make dev
. dev/bin/activate
make install-dev
make test
