Phase 2 P2.2: new § 1 page (skeleton) — network + access security; verifiable content + TODO for data-security policy and interconnect (via create-page on MediaWiki MCP Server)

New page

This page describes how Anunna is connected and how access to it is secured.

== Network ==

Internally, the compute nodes and the [[Filesystems | Lustre filesystem]] are linked by a high-speed, low-latency interconnect, which is what lets the parallel filesystem and multi-node jobs perform well. 

From outside, the cluster is reached over SSH at <code>login.anunna.wur.nl</code> (TCP port 22). Access may be restricted to certain IP ranges, and some services are only reachable over the WUR VPN. See [[Log in to Anunna]] for how to connect.

== Authentication ==

You log in with your WUR account. For stronger protection you can add multi-factor authentication to your SSH access using a hardware security key — see [[Using a hardware key for better security]]. You can also configure key-based login so you are not prompted for a password each time; see [[Ssh without password]].

== Data security ==



For how file and folder permissions work on the cluster, see [[Shared folders]]. For storing confidential data, contact the HPC team via [[Support]].
