aws-security-viz -- A tool to visualize aws security groups

DESCRIPTION

Need a quick way to visualize your current aws/amazon ec2 security group configuration? aws-security-viz does just that based on the EC2 security group ingress configuration.

FEATURES

Output to any of the formats that Graphviz supports.
EC2 classic and VPC security groups

INSTALLATION

  $ gem install aws_security_viz
  $ aws_security_viz --help

DEPENDENCIES

graphviz with triangulation brew install graphviz --with-gts

USAGE

To generate the graph directly using AWS keys

  $ aws_security_viz -a your_aws_key -s your_aws_secret_key -f viz.svg --color=true

To generate the graph using an existing security_groups.json (created using aws-cli)

  $ aws_security_viz -o data/security_groups.json -f viz.svg --color

To generate a web view

  $ aws_security_viz -a your_aws_key -s your_aws_secret_key -f aws.json --renderer navigator

Generates two files: aws.json and navigator.html.
The json file name needs to be passed in as a html fragment identifier.
The generated graph can be viewed in a webserver e.g. http://localhost:3000/navigator.html#aws.json by using ruby -run -e httpd -- -p 3000

DOCKER USAGE

If you don't want to install the dependencies and ruby libs you can execute aws-security-viz inside a docker container. To do so, follow these steps:

Clone this repository, open it in a console.
Build the docker container: docker build -t sec-viz .
Run the container: docker run -i --rm -t -p 3000:3000 -v $(pwd)/aws-viz:/aws-security-viz --name sec-viz sec-viz (Description: -i interactive shell, --rm remove the container after usage, -t attach this terminal to it, -p 3000:3000 we expose port 3000 for the HTTP server, -v $(pwd)/aws-viz:aws-security-viz mount tmp directory for generated artifacts, -name sec-viz the container will have the same name as the image we will start)
Now you can use the tool as described in usage. Make sure that you use the commands with bundler exec as prefix. For example: aws_security_viz -a your_aws_key -s your_aws_secret_key -f aws.json.
To start the web view, execute ruby -run -e httpd -- -p 3000 in the container. You can open it with your local browser at http://0.0.0.0:3000/. There you can view the generated images and the graph. Use Ctrl+C to close the HTTP server.
Terminate the docker container by typing exit in the console.

Help

$ aws_security_viz --help
Options:
  -a, --access-key=<s>       AWS access key
  -s, --secret-key=<s>       AWS secret key
  -e, --session-token=<s>    AWS session token
  -r, --region=<s>           AWS region to query (default: us-east-1)
  -v, --vpc-id=<s>           AWS VPC id to show
  -o, --source-file=<s>      JSON source file containing security groups
  -f, --filename=<s>         Output file name (default: aws-security-viz.png)
  -c, --config=<s>           Config file (opts.yml) (default: opts.yml)
  -l, --color                Colored node edges
  -u, --source-filter=<s>    Source filter
  -t, --target-filter=<s>    Target filter
  -h, --help                 Show this message

Advanced configuration

You can generate a configuration file using the following command:

  $ aws_security_viz setup [-c opts.yml]

The opts.yml file lets you define the following options:

Grouping of CIDR ips
Define exclusion patterns
Change graphviz format (neato, dot, sfdp etc)

DEBUGGING

To generate the graph with debug statements, execute the following command

$ DEBUG=true aws_security_viz -a your_aws_key -s your_aws_secret_key -f viz.svg

If it doesn't indicate the problem, please share the generated json file with me @ whynospam-awsviz@yahoo.co.in

You can send me an obfuscated version using the following command:

$ DEBUG=true OBFUSCATE=true aws_security_viz -a your_aws_key -s your_aws_secret_key -f viz.svg

Execute the following command to generate the json. You will need aws-cli to execute the command

aws ec2 describe-security-groups

EXAMPLES

Graphviz export

Navigator view

Via navigator renderer aws_security_viz -a your_aws_key -s your_aws_secret_key -f aws.json --renderer navigator

JSON view

Via json renderer aws_security_viz -a your_aws_key -s your_aws_secret_key -f aws.json --renderer json
