**ssh-audit** is a tool for ssh server & client configuration auditing.

[jtesta/ssh-audit](https://github.com/jtesta/ssh-audit/) (v2.0+) is the updated and maintained version of ssh-audit forked from [arthepsy/ssh-audit](https://github.com/arthepsy/ssh-audit) (v1.x) due to inactivity.

```
* if both IPv4 and IPv6 are used, order of precedence can be set by using either `-46` or `-64`.
* batch flag `-b` will output sections without header and without empty lines (implies verbose flag).
* verbose flag `-v` will prefix each line with section type and algorithm name.
* an exit code of 0 is returned when all algorithms are considered secure (for a standard audit), or when a policy check passes (for a policy audit).

Basic server auditing:
```
ssh-audit localhost
ssh-audit 127.0.0.1
ssh-audit 127.0.0.1:222
ssh-audit ::1
ssh-audit [::1]:222
```

To run a standard audit against many servers (place targets into servers.txt, one on each line in the format of `HOST[:PORT]`):

```
ssh-audit -T servers.txt
```

To audit a client configuration (listens on port 2222 by default; connect using `ssh -p 2222 anything@localhost`):

```
ssh-audit -c
```

To audit a client configuration, with a listener on port 4567:
```
ssh-audit -c -p 4567
```

To  list all official built-in policies (hint: use resulting policy names with `-P`/`--policy`):
```
ssh-audit -L
```

To run a policy audit against a server:
```
ssh-audit -P ["policy name" | path/to/server_policy.txt] targetserver
```

To run a policy audit against a client:
```
ssh-audit -c -P ["policy name" | path/to/client_policy.txt]
```

To run a policy audit against many servers:
```
ssh-audit -T servers.txt -P ["policy name" | path/to/server_policy.txt]
```

To create a policy based on a target server (which can be manually edited):
```
ssh-audit -M new_policy.txt targetserver
```

### Server Policy Audit Example
Below is a screen shot of the policy auditing output when connecting to an un-hardened Ubuntu Server 20.04 machine (hint: use `-L`/`--list-policies` to see names of built-in policies to use with `-P`/`--policy`):

After applying the steps in the hardening guide (see below), the output changes to the following:

* if both IPv4 and IPv6 are used, order of precedence can be set by using either `-46` or `-64`.
* batch flag `-b` will output sections without header and without empty lines (implies verbose flag).
* verbose flag `-v` will prefix each line with section type and algorithm name.
* an exit code of 0 is returned when all algorithms are considered secure (for a standard audit), or when a policy check passes (for a policy audit).

Basic server auditing:
```
ssh-audit localhost
ssh-audit 127.0.0.1
ssh-audit 127.0.0.1:222
ssh-audit ::1
ssh-audit [::1]:222
```

To run a standard audit against many servers (place targets into servers.txt, one on each line in the format of `HOST[:PORT]`):

```
ssh-audit -T servers.txt
```

To audit a client configuration (listens on port 2222 by default; connect using `ssh -p 2222 anything@localhost`):

```
ssh-audit -c
```

To audit a client configuration, with a listener on port 4567:
```
ssh-audit -c -p 4567
```

To  list all official built-in policies (hint: use resulting policy names with `-P`/`--policy`):
```
ssh-audit -L
```

To run a policy audit against a server:
```
ssh-audit -P ["policy name" | path/to/server_policy.txt] targetserver
```

To run a policy audit against a client:
```
ssh-audit -c -P ["policy name" | path/to/client_policy.txt]
```

To run a policy audit against many servers:
```
ssh-audit -T servers.txt -P ["policy name" | path/to/server_policy.txt]
```

To create a policy based on a target server (which can be manually edited):
```
ssh-audit -M new_policy.txt targetserver
```

### Server Policy Audit Example
Below is a screen shot of the policy auditing output when connecting to an un-hardened Ubuntu Server 20.04 machine (hint: use `-L`/`--list-policies` to see names of built-in policies to use with `-P`/`--policy`):

* if both IPv4 and IPv6 are used, order of precedence can be set by using either `-46` or `-64`.
* batch flag `-b` will output sections without header and without empty lines (implies verbose flag).
* verbose flag `-v` will prefix each line with section type and algorithm name.
* an exit code of 0 is returned when all algorithms are considered secure (for a standard audit), or when a policy check passes (for a policy audit).

Basic server auditing:
```
ssh-audit localhost
ssh-audit 127.0.0.1
ssh-audit 127.0.0.1:222
ssh-audit ::1
ssh-audit [::1]:222
```

To run a standard audit against many servers (place targets into servers.txt, one on each line in the format of `HOST[:PORT]`):

```
ssh-audit -T servers.txt
```

To audit a client configuration (listens on port 2222 by default; connect using `ssh -p 2222 anything@localhost`):

```
ssh-audit -c
```

To audit a client configuration, with a listener on port 4567:
```
ssh-audit -c -p 4567
```

To  list all official built-in policies (hint: use resulting policy names with `-P`/`--policy`):
```
ssh-audit -L
```

To run a policy audit against a server:
```
ssh-audit -P ["policy name" | path/to/server_policy.txt] targetserver
```

To run a policy audit against a client:
```
ssh-audit -c -P ["policy name" | path/to/client_policy.txt]
```

To run a policy audit against many servers:
```
ssh-audit -T servers.txt -P ["policy name" | path/to/server_policy.txt]
```

To create a policy based on a target server (which can be manually edited):
```
ssh-audit -M new_policy.txt targetserver
```

### Server Standard Audit Example
Below is a screen shot of the standard server-auditing output when connecting to an unhardened OpenSSH v5.3 service:

### Server Policy Audit Example
Below is a screen shot of the policy auditing output when connecting to an un-hardened Ubuntu Server 20.04 machine (hint: use `-L`/`--list-policies` to see names of built-in policies to use with `-P`/`--policy`):

After applying the steps in the hardening guide (see below), the output changes to the following:
