The e-U Virtual
Campus is an initiative launched in 2003 under the Portuguese Action Plan for
the Information Society, of which the FCCN is the technical coordinator. The
e-U involves Services, Content, Applications and Mobile Communications Networks
(inside and outside the University) for users of member institutions,
encouraging and facilitating the production, access and sharing of knowledge
among them.
The chief aims of
the e-U Virtual Campus are:
- To foster the creation of on-line University
services;
- To produce and share academic content;
- To create Higher Education communities, with
three specific components:
1. Investment in establishing Services and
Content, available at any time,
in any place;
2. Massification
of laptop computers usage ("one for everyone",
student/lecturer);
3. Access to the Internet and Intranet inside and outside
the University Campus.
The aim of this
document is to define the terms and conditions of participation and utilization
relative to the e-U Virtual Campus, in particular its roaming service, to apply
uniformly and equally to all the participants in the roaming process, that is: roaming
user, home institution and visited institution.
The provisions set
forth in this document may never overlap those that result from the RCTS
(Science, Technology and Society Network) user Charter. This policy should be
followed by all member institutions, whether they are the visited institution
or the home institution, and it should be reflected in the document that is
adopted internally to define the policies for the use of this Network by end users.
For the purposes of
this document, the following are regarded as participants in the roaming process:
Visiting user – User who visits an institution and tries to get the e-U Virtual Campus
network services.
Local user – Registered user that uses the services provided by e-U Virtual Campus
network in his/her home institution.
Home institution – Institution where the visiting user is registered and with which the
requests for authentication relative to the roaming process are exchanged.
Visited institution – The institutions where the visiting user physically is and where
he/she tries to get the e-U network roaming services.
NREN - National Research and
Education Network. The institution that manages and operates a national level network.
In Portugal, the NREN (RCTS) in managed by FCCN.
Under its membership of e-U Virtual Campus, the visiting user’s home institution,
should proceed as follows:
- Provide its authorized users, and them alone, with
valid credentials.
- Prepare and disseminate to its users a document
that defines an AUP (Acceptable User Policy). This should make a point of
including: the description of the roaming service provided; the obligations
contained in this document, with any adaptations that may be imposed; and contact
points and means of obtaining information on questions related to this matter.
- Take the necessary and sufficient measures so that
its roaming users are made fully
aware of the content and implications of the document mentioned in the
preceding point.
- Ensure that all the records of an authenticated session,
generated for a roaming user in a visited institution and sent to the home institution, are stored. Throughout
the authenticated session the information on the roaming user must be kept as accurate and complete as
possible, so that he/she can be identified, if necessary.
- Give technical and administrative support to both
the local users and visiting users presented at any visited institution.
The visited
institution by the roaming user, should proceed as follows:
- Provide the roaming
users, duly authenticated and authorized by the home institution, with
at least the minimum set of services defined to the e-U Virtual Campus
network.
- Publicize the roaming
service in an appropriate place, as well as the respective terms and
conditions of use, and the level of security with which the authentication data
must be transmitted.
- Guarantee that the mechanism for transmitting
credentials has a sufficient level of security. If this is not possible, the roaming user should be guaranteed the
possibility of starting a secure session.
- Ensure that all the logs from authentication or network
sessions, generated during the roaming process for any roaming user, are stored.
- Send information about the start and stop of a network
session to the home institution. The
information exchanged between institutions
(home and visited) during the authentication
session should be as accurate and complete as possible.
- To determine, if applicable, what other network
resources are made available to the roaming
users in addition to the minimum set
of services established for the e-U Virtual Campus network.
- All the support given to the roaming user must be provided by the home institution. The visited institution should only be
involved in the support process, if it is concluded that a problem originates
there and , even so, is not obliged to provide this support.
- The visited
institution may block access to the network services to a roaming user, an institution or an
NREN, whenever this is justified, informing FCCN/CERT.PT (www.cert.pt/) about
the kind of block and the reasons for imposing it. The FCCN/CERT.PT should
inform the affected institution/NREN about this measure and the respective
reason.
- Should it be asked to do so by the CERT.PT, the visited institution must provide all
the information available that will help to identify the home institution of the roaming user involved in a security
incident.
The roaming
user must follow and accept the following principles:
- The user is
fully responsible for the confidentiality of his/her credentials.
- If the user
credentials are (or thought to be) compromised, the user must report
this occurrence to the home institution as soon as possible,
so that they can be cancelled and new ones assigned.
- To comply with the AUP established and publicized
by the visited institution for the
e-U Virtual Campus network.
- All roaming
users must be authenticated to their home
institution, so that they can be given network access within the visited institution.
- Roaming users should
only attempt the authentication process after ensuring that their credentials
will be transmitted in a secure form.
- The roaming
users must be aware that, after successful authentication, the network
resources assigned to him/her, may only comply with the minimum set of services defined for the e-U, Virtual Campus network,
and he/she should therefore not expect the same level of service found at the home institution.
In the context of the e-U Virtual Campus roaming
service and the European eduroam network, the FCCN (Portuguese NREN) is liable for the following:
- The NREN is liable for managing and
maintaining the national level authentication proxy servers.
- The NREN will provide redundancy within authentication
proxy servers, specifically, with more than one proxy server.
- If technically possible, the integrity of relevant
information received by the national authentication proxy servers, which is to
be re-routed to another institution or NREN, must be assured.
- The NREN can block access to the roaming users of a particular home institution in the national
authentication proxy servers. Such blocking and the reasons for it must be
communicated to whoever is liable in the institutions involved via CERT.PT.
- The NREN can block a particular institution in the
national authentication proxy servers if this institution deliberately fails to
comply with the provisions set forth in this document.
- The NREN must provide monitoring mechanisms that allow
to obtain information about the state of the national authentication proxy servers.
The results must be made available to interested parties, in particular to roaming users.
- The NREN is not liable for the confidentiality
of data transmitted between a roaming
user and his home institution.
This must be ensured by the parties involved in the remote access process, that
is, the roaming user and his home institution.
The trust model
between institutions participating in the e-U Virtual Campus network, with
respect to the mobility of students and lecturers, is based on a hierarchical authentication
infrastructure whose administration is distributed.
To reduce or
mitigate any security incidents inherent to the misuse of users’ credentials or
the improper use of resources, auditing tools must be provided and made
accessible to those involved in the roaming process. These tools should enable
the unambiguous tracing of a specific user or institution.
This annex defines
the logged information to be sent by the visited
institution to the home
institution regarding any session by a roaming
user, as well as the responsibilities of both in terms of data retention.
The visited institution must send the
accounting information to the home
institution at the start and end of each session by a roaming user, in particular the start
and stop accounting logs.
The visited institution must also keep
authentication logs and session start and stop logs for 6 months (level 2 –
accounting from access points; level 3 – DHCP accounting).
The home institution must keep the
authentication logs and session start and stop information of its users for a
period of 6 months.
The visited institution must guarantee the association
of level 3 to level 2 logging and, desirably, implement IP anti-spoofing
mechanisms into the infrastructure.
The
computer systems of the visited and home institutions and those of the
national authentication proxy servers operated by the FCCN involved in the
accounting logs must have their clocks synchronized via the NTP – Network Time
Protocol – preferably using the ntp01.fccn.pt and ntp02.fccn.pt servers.
This Annex describes the support model that the
NREN will provide for the institutions envolved in the e-U Virtual Campus initiative.
