polscan (short for "Policy Scanner")
- Makes your DevOps server configuration/security/automation policies explicit
- Easily detects configuration drift (Puppet 2/3/4)
- Provides details on package updates (Debian, PHP, Gem, CVEs via debsecan)
- Provides basic security checks (SSH, NFS, sysctl)
- Explains policies by
- linking references
- having reasonable descriptions
- suggesting quick fixes
- referencing to security standards
- Has zero setup, no dependencies: Bash 4.2, SSH
- Scales up to at least 2000 hosts * 50 scanners ~ 100k findings
Policies are implemented by small shell snippets and thus polscan is easily extensible by your own specific policies. To make it easy to use it comes with host discovery solutions for typical automation setups (Chef, Puppet, MCollective).

Note: polscan is intentionally limited to Debian and for simplicity tries not to implement any distro-specific dependencies.
How to run it
polscan keeps results on a daily basis so it makes sense to set up a daily cron.
Or just run it from the source directory
./polscan # To re-scan all hosts ./polscan -l 'server1 server2' # To scan specific hosts
For simplicity all results are store in files in plain text and JSON. The JSON files are used by the static HTML viewer that can be used to inspect the result archive.
To quickly expose the static results in any webservers document root run the following commands from the directory you installed polscan into:
cp -r www /var/www/polscan mkdir /var/www/polscan/results ln -s /var/www/polscan/results results
