## 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`
* libxml2 `brew install libxml2`*

## 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
```

* Generates two files: aws.json and view.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/view.html#aws.json by using `python -m SimpleHTTPServer 3000` (python2) or `python -m http.server 3000` (python3)

### 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](https://github.com/aws/aws-cli) to execute the command

`aws ec2 describe-security-groups`
