---+ !!*LHCONE Acceptable Use Policy (AUP)*

As agreed upon by the participants [[https://indico.cern.ch/event/983436/][LHCOPN-ONE meeting]] on 2021/03/23. 


%TOC%

---++ *Preamble*

The LHCONE is a dedicated network architecture inter-connecting participating HEP sites and allowing those sites to pool their computing resources for a more efficient distribution, storage, processing and analysis of HEP data. This AUP is to ensure an appropriate secure scientific use of the overlay network and to protect the connected sites.

---+++ Process to include additional collaborations to LHCONE
Any scientific collaboration wishing to use the LHCONE services can ask to participate. The admission process is the following:
   1. The collaboration presents itself, its computing model and network requirements to the community during a LHCONE meeting
   1. The collaboration produces this information
      * link to collaboration's description and documentation
      * link to management board
      * list of participating sites
      * documentation of security policies
      * email address(es) of contact people
   1. The LHCONE community accepts or rejects based on the impact on the LHCONE. Among criteria to be used in the evaluation:
      * the collaboration must be related to Particle Physics
      * a major fraction of the sites and collaboration's resources (CPUs and storage) must be already connected to LHCONE
      * commitment to meet the technical and security requirements listed at the next point
      * the bandwidth demand shouldn't have a significant impact on existing LHCONE data transfers
      * commitment to participating and contributing to LHCONE meetings
   1. Requirements to fulfil:
      * comply with the WLCG security policies
      * comply with the technical specifications of the LHCONE AUP concerning announcement of IP Prefixes (LHCONE Prefixes) and authorized source and destinations nodes (LHCONE Nodes)
      * acknowledge the LHCONE AUP
   1. The LHCONE community chairman informs the WLCG Management Board and WLCG Overview Board of the request and the decision
      * [[http://wlcg.web.cern.ch/collaboration/management/management-board][WLCG Management Board]]
      * [[http://wlcg.web.cern.ch/collaboration/management/overview-board][WLCG Overview Board]]

---++ *Scope*

This AUP is a set of policy requirements that applies to all LHCONE Sites. Its purpose is to define:
   * which IP Prefixes must be announced for LHCONE traffic;
   * which nodes can be LHCONE nodes;
   * which HEP sites can be LHCONE sites;
   * consequences for non-compliance with this AUP.

---++ *LHCONE !L3VPN Acceptable Use Policy (AUP)*

---+++ Eligibility for becoming a LHCONE Site

   * Only HEP sites of one of the participating collaborations can be connected to the LHCONE. Membership with a collaboration can be verified by asking the contact emails provided in the [[#AnchorCOLLABORATIONS][Participanting Collaborations section]];
   * In order to be allowed to connect to the LHCONE !L3VPN, a candidate site has to acknowledge this AUP. To confirm they read, understand and commit to abide to the AUP, the designated site representative has to
      * join the mailing list lhcone-operations@cern.ch (https://e-groups.cern.ch/e-groups/EgroupsSubscription.do?egroupName=lhcone-operations)
      * send an email to the mailing list lhcone-operations@cern.ch writing that the site acknowledges  the AUP
   * Once the two items above are confirmed, the LHCONE Manager will reply to the acknowledgement with the authorization to connect.

---+++ Announcement of IP Prefixes for LHCONE Traffic (LHCONE Prefix)

A LHCONE site announces to the LHCONE provider's router a limited amount of IP prefixes (subnets) from its own public address range (see [[https://twiki.cern.ch/twiki/bin/view/LHCONE/LhcOneHowToConnect][here]] for instructions on how to connect to LHCONE). These prefixes are called _LHCONE prefixes_.

All LHCONE traffic is subject to the following conditions:
   * Traffic injected into the LHCONE must originat only from addresses that belong to a LHCONE prefix;
   * Traffic injected into the LHCONE must send only to addresses that belong to a LHCONE prefix.

This is essential to ensure traffic symmetry through any stateful firewall, i.e. enabling a proper TCP handshake. In addition, some sites might use the announced LHCONE prefixes for traffic filtering in their stateful or stateless firewalls. Alternatively, LHCONE sites can decide independently whether the LHCONE traffic is allowed to bypass their own perimeter firewall or not.

All LHCONE prefixes must be declared in the LHCONE prefixes database

---+++ Authorized source and destinations nodes (LHCONE Nodes)

IP addresses from the LHCONE prefixes must be assigned to _LHCONE nodes_, i.e. only to
   * Nodes that are currently and primarily used to distribute, store, process and analyse the data generated by HEP sites;
   * Routers and switches for routing such data;
   * !perfSONAR probes and correspondent management infrastructure used for LHCONE.

The following devices must not be LHCONE nodes:
   * Generic campus devices (desktop and portable computers, wireless devices, printers, VOIP phones....).

For sites which cannot segregate their networks, the following devices are tolerated:
   * Computing nodes, storage elements and web servers not related with HEP computing services as long as they are managed according to the security policies agreed by each participating collaboration. The number of such devices shall be kept to a minimum. Relevant security policy documents are listed in the related section. [[#AnchorCOLLABORATIONS][related section]].

---+++ Security incident reporting

Any violation of an explicit or implied security policy is termed a security incident. In line with WLCG security policies requirements, in addition to following local procedures, LHCONE sites must report suspected security incidents to wlcg-security-officer@cernNOSPAMPLEASE.ch.and follow the [[https://wlcg.web.cern.ch/computer-security][WLCG security incident response procedures]].

---+++ Violations and non-compliance with the AUP

LHCONE participants are encouraged to resolve possible policy violations and non-compliance issues with one another, for instance via  lhcone-operations@cernNOSPAMPLEASE.ch. 
Severe or repeated violations may be escalated to *the WLCG Management Board and the offending LHCONE site may be disconnected temporarily or indefinitely from LHCONE.

In addition, when confronted to policy violations or suspected security incidents, a LHCONE Site is allowed to drop the prefixes announced by the offending LHCONE site at any time, disconnect itself from the LHCONE, as long as the changes are announced to the mailing list lhcone-operations@cern.ch.
The 65010:ASN [[https://twiki.cern.ch/twiki/bin/view/LHCONE/LhcOneVRF#BGP_communities][LHCONE BGP community]] can be used to ensure symmetry.

---++ *Roles and Responsibilities*

*LHCONE Sites*
   * Must abide by this AUP and all others applicable WLCG security policies;
   * Must connect only resources relevant to fulfilling the PREAMBLE of this AUP;
   * May define (in addition to the WLCG security policies) their own local security requirements with regard to traffic arriving from the LHCONE;
   * May decide independently if the LHCONE traffic can bypass their own perimeter firewall or not;
   * Must declare the list of their own LHCONE prefixes in the [https://twiki.cern.ch/twiki/bin/view/LHCONE/LhcOneVRF#LHCONE_Prefixes_Database][LHCONE Prefixes Database] and keep their entries  up to date.

*LHCONE Providers*
   * Agrees to only connect to LHCONE, organizations and/or route prefixes that the LHCONE Manager has agreed to accept.
   * Agrees to announce any newly connected sites or prefixes to the lhcone-operations mailing list (lhcone-operations@cernNOSPAMPLEASE.ch)
   * Agrees to honor any written LHCONE disconnection requests from the WLCG Management Board for any organization that provider connects to LHCONE 
   * Agrees to implement BGP filtering based on LHCONE BGP communities.

*Management Board*
   * Each Management Board of any LHCONE collaboration can request the disconnection from LHCONE of any LHCONE site which is not compliant with this AUP. In case of disputes, the ultimate and authoritative request must come from the WLCG Management Board 
   * The WLCG Management Board has the final and ultimate jurisdiction on its affiliated HEP/LHCONE sites and collaboration and the authority to withdraw a collaboration or ask a site to get disconnected
