What is an Open-AudIT Collector?
A collector is Open-AudIT set to collector mode, where its sole purpose is to collect asset information. While the collector is capable of discovering multiple networks, it is perfect for running discoveries on its own subnet.
How does it work?
When in Collector / Server configuration you can have a collector Open-AudIT running on a subnet and discovering devices where the collector is controlled by the server. Once installed and setup, control of the collector is performed on the server. The only required network ports between the collector and server are 80 or 443.
Open-AudIT Cloud and Open-AudIT Enterprise both work standalone and with collectors. You should use a collector for any difficult to reach devices that you need to audit or in cases where your security only allows port 80 or 443 to be used to access a network. Both products come with 1 collector free of charge.
When will I need to use one?
When you have segregated networks that you need to audit. It saves firewall changes as it uses ports 80 or 443 and shouldn’t cause any concern for the security team. There is no requirement for the Open-AudIT server to have full access to the network on which the collector runs.
How can I figure out how many collectors I need?
You should consider what you want to audit, the frequency of audits and how many nodes you want to audit and use that as a starting point to determine the number you need (if any).
- Have one collector per subnet.
- One collector per many subnets.
- One collector behind a firewall (via port 80 or 443).
