Track assets by hostname across enterprise toolsets for analyst context and rouge device detection.
The input data can be any logs that relate to an asset by hostname, for example:
- {your vendor} EDR logs
- Azure AD device logs
- {your vendor} Anti-Virus logs
- Windows logs
You can also configure requirements as to what an asset has to have as a recently logged security tool (such as your EDR and AV clients).
A Postgres database is recommended.
CREATE DATABASE asset_tracking;
CREATE USER asset_tracker WITH ENCRYPTED PASSWORD 'yourpass';
GRANT ALL PRIVILEGES ON DATABASE asset_tracking TO asset_tracker;
If a Postgres database is not configured and found, a local sqlite database will be used.
You can configure the asset-tracker
via environment variables and/or configuration files.
Environment variables available for configuration:
Environment Variable | Default | Description |
---|---|---|
ASSET_TRACKING_DATA_DIR | Current working dir | Only used if you use SqLite for the database. |
ASSET_TRACKING_SERVER_HOSTNAME_REGEX_STANDARD | Regex to match your enterprise server names. | |
ASSET_TRACKING_WORKSTATION_HOSTNAME_REGEX_STANDARD | " " workstation names. | |
ASSET_TRACKING_DB_USER | postgres | Postgres username |
ASSET_TRACKING_DB_PASS | Postgres user password | |
ASSET_TRACKING_DB_HOST | Postgres server hostname | |
ASSET_TRACKING_DB_PORT | 5432 | Postgres port |
ASSET_TRACKING_REQUIRE_ALL_ATTRIBUTES | Comma separated list of required security attributes (tools/log sources) | |
ASSET_TRACKING_REQUIRE_ONE_ATTRIBUTE | Comma separated list of which an asset has to have one to be compliant. | |
ASSET_TRACKING_CONFIG_PATH | Path to a .ini config file that can be used to override all settings. |
Default paths searched for configuration files:
/etc/ace/asset_tracking.ini
~/.config/asset_tracking.ini
Finally, any configuration file pointed to by the ASSET_TRACKING_CONFIG_PATH environment variable overrides any previous configuration items.
The configuration loaded from disk will be checked for settings if an environment variable was not explicitly set for any settings.
Configuration example:
[asset_tracking]
db_host=
db_port=5432
db_user=asset_tracker
db_pass=
require_all_tools = your_fav_vendor_edr_tool,your_fav_dlp_tool,etc.
require_one_of_tools = symantec,mcafee,defender,etc.
max_asset_absence_days = 6
max_attribute_absence_days = 7
server_hostname_regex_standard =
workstation_hostname_regex_standard =
Note, the the server and workstation regex is actually picket up and used by a different detection tool that leverages asset-tracking
for the time being.
