AWS IR
======

Python installable command line utility for mitigation of instance and key compromises.

Documentation
-------------

Read the full documentation on `read the docs `__.

Quickstart
----------

For more information see the `quickstart `__.

Installation
************

``pip install aws_ir``

Or see `installing `__.

AWS Credentials
***************

Ensure aws credentials are configured under the user running aws_ir as documented `by amazon `__.

Check back soon for an IAM policy featuring the minimum set of required permissions

Optional Arguments
******************

.. code-block:: bash

usage: aws_ir [-h] [--version] [--verbose] [--profile PROFILE]
[--case-number CASE_NUMBER]
[--examiner-cidr-range EXAMINER_CIDR_RANGE]
[--bucket-name BUCKET_NAME] [--dry-run]
{instance-compromise,key-compromise} ...

Incident Response command line for Amazon Web Services. This command line
interface is designed to process host and key based incursions without delay
or error.

positional arguments:
{instance-compromise,key-compromise}
instance-compromise
key-compromise

optional arguments:
-h, --help show this help message and exit

--version show program's version number and exit
--verbose log debug messages
--profile PROFILE A named boto profile to use instead of the default
profile.
--case-number CASE_NUMBER
The case number to use., usually of the form
"cr-16-053018-2d2d"
--examiner-cidr-range EXAMINER_CIDR_RANGE
The IP/CIDR for the examiner and/or the tool. This
will be added as the only allowed range in the
isolated security group.
--bucket-name BUCKET_NAME
Optional. The id of the s3 bucket to use. This must
already exist
--dry-run Dry run. Pass dry run parameter to perform API calls
but will not modify any resources.

Key Compromise
**************

The ``aws_ir`` subcommand ``key-compromise`` disables access keys in the case of a key compromise.
It's single argument is the access key id, he compromised key is disabled via the AWS api.

.. code-block:: bash

usage: aws_ir key-compromise [-h] --access-key-id ACCESS_KEY_ID
[--plugins PLUGINS]

optional arguments:
-h, --help show this help message and exit
--access-key-id ACCESS_KEY_ID
--plugins PLUGINS Run some or all of the plugins in a custom order.
Provided as a comma separated listSupported plugins:
disableaccess_key,revokests_key

Below is the output of running the ``key-compromise`` subcommand.

.. code-block:: bash

$ aws_ir key-compromise --access-key-id AKIAINLHPIG64YJXPK5A

Instance Compromise
*******************

The ``aws_ir`` subcommand ``instance-compromise`` preserves forensic artifacts from a compromised instance after isolating the instance.
Once all artifacts are collected and tagged the compromised instance is powered off.
The ``instance-compromise`` subcommand takes three arguments, the ``instance-ip`` of the compromised instance, a ``user`` with ssh access to the target instance, and the ``ssh-key`` used for authentication.

Currently ``user`` must be capable of passwordless sudo for memory capture to complete. If ``user`` does not have passwordless sudo capabilities all artifiacts save for the memory capture will be gathered.

.. code-block:: bash
$ aws_ir instance-compromise -h
usage: aws_ir instance-compromise [-h] [--target TARGET] [--targets TARGETS]
[--user USER] [--ssh-key SSH_KEY]
[--plugins PLUGINS]

optional arguments:
-h, --help show this help message and exit
--target TARGET instance-id|instance-ip
--targets TARGETS File of resources to process instance-id or ip-address.
--user USER this is the privileged ssh user for acquiring memory from
the instance. Required for memory only.
--ssh-key SSH_KEY provide the path to the ssh private key for the user.
Required for memory only.
--plugins PLUGINS Run some or all of the plugins in a custom order.
Provided as a comma separated list of supported plugins:
examineracl_host,gather_host,isolate_host,snapsh
otdisks_host,stop_host,tag_host,get_memory

AWS IR saves all forensic artifacts except for disk snapshots in an s3 bucket created for each case. Disk snapshots are tagged with the same case number as the rest of the rest of the artifacts.

Below is the output of running the ``instance-compromise`` subcommand.

.. code-block:: bash

Instance Compromise -- Isolation Achieved

See below that I've connected to the compromised workstation from my examiner IP address. SSH is all
that is permitted due to the NACL and Security Group additions.
