The Infection Monkey agent has two steps before attempting to exploit a victim, scanning and fingerprinting, it's possible to customize both steps in the configuration files.
The Infection Monkey agent takes two steps before attempting to exploit a victim, scanning and fingerprinting. It's possible to customize both steps in the configuration files.
## Scanning
Currently there are two scanners, [`PingScanner`][ping-scanner] and [`TcpScanner`][tcp-scanner] both inheriting from [`HostScanner`][host-scanner].
Currently there are two scanners, [`PingScanner`][ping-scanner] and [`TcpScanner`][tcp-scanner], both inheriting from [`HostScanner`][host-scanner].
The sole interface required is the `is_host_alive` interface, which needs to return True/False.
[`TcpScanner`][tcp-scanner] is the default scanner and it checks for open ports based on the `tcp_target_ports` configuration setting.

[`PingScanner`][ping-scanner] sends a ping message using the host OS utility `ping`.

## Fingerprinting
Fingerprinters are modules that collect server information from a specific victim. They inherit from the [`HostFinger`][host-finger] class and are listed under `finger_classes` configuration option.

Currently implemented Fingerprint modules are:
The currently implemented Fingerprint modules are:
1. [`SMBFinger`][smb-finger] - Fingerprints target machines over SMB. Extracts computer name and OS version.
2. [`SSHFinger`][ssh-finger] - Fingerprints target machines over SSH (port 22). Extracts the computer version and SSH banner.
3. [`PingScanner`][ping-scanner] - Fingerprints using the machines TTL, to differentiate between Linux and Windows hosts.
4. [`HTTPFinger`][http-finger] - Fingerprints over HTTP/HTTPS, using the ports listed in `HTTP_PORTS` in the configuration. Returns the server type and if it supports SSL.
5. [`MySQLFinger`][mysql-finger] - Fingerprints over MySQL (port 3306). Extracts MySQL banner info - Version, Major/Minor/Build and capabilities.
6. [`ElasticFinger`][elastic-finger] - Fingerprints over ElasticSearch (port 9200). Extracts the cluster name, node name and node version.
1. [`SMBFinger`][smb-finger] - Fingerprints will target machines over SMB and extract the computer name and OS version.
2. [`SSHFinger`][ssh-finger] - Fingerprints will target machines over SSH (port 22) and extract the computer version and SSH banner.
3. [`PingScanner`][ping-scanner] - Fingerprints will use the machine's TTL to differentiate between Linux and Windows hosts.
4. [`HTTPFinger`][http-finger] - Fingerprints over HTTP/HTTPS, using the ports listed in `HTTP_PORTS` in the configuration, will return the server type and if it supports SSL.
5. [`MySQLFinger`][mysql-finger] - Fingerprints over MySQL (port 3306) will extract MySQL banner info - version, major/minor/build and capabilities.
6. [`ElasticFinger`][elastic-finger] - Fingerprints over ElasticSearch (port 9200) will extract the cluster name, node name and node version.
## Adding a scanner/fingerprinter
To add a new scanner/fingerprinter, create a new class that inherits from [`HostScanner`][host-scanner] or [`HostFinger`][host-finger] (depending on the interface). The class should be under the network module and should be imported under [`network/__init__.py`](https://github.com/guardicore/monkey/blob/master/monkey/infection_monkey/network/__init__.py).

To be used by default, two files need to be changed - [`infection_monkey/config.py`](https://github.com/guardicore/monkey/blob/master/monkey/infection_monkey/config.py) and [`infection_monkey/example.conf`](https://github.com/guardicore/monkey/blob/master/monkey/infection_monkey/example.conf) to add references to the new class.

At this point, the Monkey knows how to use the new scanner/fingerprinter but to make it easy to use, the UI needs to be updated. The relevant UI file is [`monkey_island/cc/services/config.py`](https://github.com/guardicore/monkey/blob/master/monkey/monkey_island/cc/services/config.py).
