cbapi: Carbon Black API for Python¶
cbapi provides a straightforward interface to the Carbon Black products: CB Protection, Response, and Defense. This library provides a Pythonic layer to access the raw power of the REST APIs of all CB products, making it trivial to do the easy stuff and handling all of the “sharp corners” behind the scenes for you. Take a look:
>>> from cbapi.response import CbResponseAPI, Process, Binary, Sensor >>> # >>> # Create our CbAPI object >>> # >>> c = CbResponseAPI() >>> # >>> # take the first process that ran notepad.exe, download the binary and read the first two bytes >>> # >>> c.select(Process).where('process_name:notepad.exe').first().binary.file.read(2) 'MZ' >>> # >>> # if you want a specific ID, you can put it straight into the .select() call: >>> # >>> binary = c.select(Binary, "24DA05ADE2A978E199875DA0D859E7EB") >>> # >>> # select all sensors that have ran notepad >>> # >>> sensors = set() >>> for proc in c.select(Process).where('process_name:evil.exe'): ... sensors.add(proc.sensor) >>> # >>> # iterate over all sensors and isolate >>> # >>> for s in sensors: ... s.network_isolation_enabled = True ... s.save()
If you’re more a CB Protection fellow, then you’re in luck as well:
>>> from cbapi.protection.models import FileInstance >>> from cbapi.protection import CbProtectionAPI >>> # >>> # Create our CB Protection API object >>> # >>> p = CbProtectionAPI() >>> # >>> # Select the first file instance >>> # >>> fi = p.select(FileInstance).first() >>> # >>> # print that computer's hostname. This automatically "joins" with the Computer API object. >>> # >>> fi.computer.name u'DOMAIN\\MYHOSTNAME' >>> # >>> # change the policy ID >>> # >>> fi.computer.policyId = 3 >>> fi.computer.save()
As of version 1.2, cbapi now provides support for CB Defense too!
>>> from cbapi.psc.defense import * >>> # >>> # Create our CB Defense API object >>> # >>> p = CbDefenseAPI() >>> # >>> # Select any devices that have the hostname WIN-IA9NQ1GN8OI and an internal IP address of 192.168.215.150 >>> # >>> devices = c.select(Device).where('hostNameExact:WIN-IA9NQ1GN8OI').and_("ipAddress:192.168.215.150").first() >>> # >>> # Change those devices' policy into the Windows_Restrictive_Workstation policy. >>> # >>> for dev in devices: >>> dev.policyName = "Restrictive_Windows_Workstation" >>> dev.save()
- Enhanced Live Response API
- The new cbapi now provides a robust interface to the CB Response Live Response capability. Easily create Live Response sessions, initiate commands on remote hosts, and pull down data as necessary to make your Incident Response process much more efficient and automated.
- Consistent API for CB Response, Protection and Defense platforms
- We now support CB Response, Protection and Defense users in the same API layer. Even better, the object model is the same for both; if you know one API you can easily transition to the other. cbapi hides all the differences between the three REST APIs behind a single, consistent Python-like interface.
- Enhanced Performance
- cbapi now provides a built in caching layer to reduce the query load on the Carbon Black server. This is especially useful when taking advantage of cbapi’s new “joining” features. You can transparently access, for example, the binary associated with a given process in CB Response. Since many processes may be associated with the same binary, it does not make sense to repeatedly request the same binary information from the server over and over again. Therefore cbapi now caches this information to avoid unnecessary requests.
- Reduce Complexity
- cbapi now provides a friendly - dare I say “fun” - interface to the data. This greatly improves developer productivity and lowers the bar to entry.
- Python 3 and Python 2 compatible
- Use all the new features and modules available in Python 3 with cbapi. This module is compatible with Python versions 2.6.6 and above, 2.7.x, 3.4.x, and 3.5.x.
- Better support for multiple CB servers
- cbapi now introduces the concept of Credential Profiles; named collections of URL, API keys, and optional proxy configuration for connecting to any number of CB Protection, Defense, or Response servers.
The new cbapi as of version 0.9.0 enforces the use of credential files.
In order to perform any queries via the API, you will need to get the API token for your CB user. See the documentation on the Developer Network website on how to acquire the API token for CB Response, CB Protection, or CB Defense.
Once you acquire your API token, place it in one of the default credentials file locations:
credentials.protectionfor CB Protection, or
credentials.defensefor CB Defense)
- (current working directory)
Credentials found in a later path will overwrite earlier ones.
The credentials are stored in INI format. The name of each credential profile is enclosed in square brackets, followed by key-value pairs providing the necessary credential information:
[default] url=https://localhost token=abcdef0123456789abcdef ssl_verify=False [prod] url=https://cbserver.prod.corp.com token=aaaaaa ssl_verify=True [otheruser] url=https://localhost token=bbbbbb ssl_verify=False
The possible options for each credential profile are:
- url: The base URL of the CB server. This should include the protocol (https) and the hostname, and nothing else.
- token: The API token for the user ID. More than one credential profile can be specified for a given server, with different tokens for each.
- ssl_verify: True or False; controls whether the SSL/TLS certificate presented by the server is validated against the local trusted CA store.
- org_key: The organization key. This is required to access the PSC, and can be found in the console. The format is
- proxy: A proxy specification that will be used when connecting to the CB server. The format is:
http://myusername:firstname.lastname@example.org:8001/where the hostname of the proxy is
proxy.company.com, port 8001, and using username/password
- ignore_system_proxy: If you have a system-wide proxy specified, setting this to True will force cbapi to bypass the proxy and directly connect to the CB server.
Future versions of cbapi will also provide the ability to “pin” the TLS certificate so as to provide certificate verification on self-signed or internal CA signed certificates.
Environment Variable Support
The latest cbapi for python supports specifying API credentials in the following three environment variables:
CBAPI_TOKEN the envar for holding the CbR/CbP api token or the ConnectorId/APIKEY combination for CB Defense/PSC.
The CBAPI_URL envar holds the FQDN of the target, a CbR , CBD, or CbD/PSC server specified just as they are in the configuration file format specified above.
The optional CBAPI_SSL_VERIFY envar can be used to control SSL validation(True/False or 0/1), which will default to ON when not explicitly set by the user.
Backwards & Forwards Compatibility¶
The previous versions (0.8.x and earlier) of cbapi and bit9Api are now deprecated and will no longer receive updates. However, existing scripts will work without change as cbapi includes both in its legacy package. The legacy package is imported by default and placed in the top level cbapi namespace when the cbapi module is imported on a Python 2.x interpreter. Therefore, scripts that expect to import cbapi.CbApi will continue to work exactly as they had previously.
Since the old API was not compatible with Python 3, the legacy package is not importable in Python 3.x and therefore legacy scripts cannot run under Python 3.
Once cbapi 1.0.0 is released, the old
cbapi.legacy.CbApi will be deprecated and removed entirely no earlier
than January 2017.
New scripts should use the
(for CB Response),
(for CB Protection), or
cbapi.defense.rest_api.CbDefenseAPI API entry points.
The API is frozen as of version 1.0; afterward, any changes in the 1.x version branch will be additions/bug fixes only. Breaking changes to the API will increment the major version number (2.x).
Let’s get started with cbapi. Once you’ve mastered the concepts here, then you can always hop over to the API Documentation (below) for detailed information on the objects and methods exposed by cbapi.
