Vuls
Agentless vulnerability scanner for Linux/FreeBSD
... use Vuls in the Local Scan mode. Fast scan mode scans without root privilege, no internet access, almost no load on the scan target server. Deep scan mode scans in more detail. It is possible to acquire the state of the server executing some commands. Vuls v0.5.0 warns not-restarting-processes which updated before but not restarting yet. And detect processes affecting software update in advance.
