CERT object in the RIPE Database
-----------------------------------
Problem:
- direct contacts (admin-c, tech-c) or indirect contacts (admin-c,
tech-c of the respective maintainer) are not necessarily point to a CERT
team;
- because of this CERT infrastructure is not reflected in the RIPE
Database, which is essential for tracing/blocking attacks, etc.;
- because of this there is no consistent approach to secure/authenticate
transactions between CERTs or a CERT and a user.


Goals: 
- to support coordination between different CERT teams/NOCs;
- to provide contact information for reports of attacks/abuse/spam;
- to support secure/authentic transactions between CERTs and users.

Object format
--------------

The proposed cert objet is a hybrid of role and mntner objects. It
inherits contact information from a role object and
authentication/authorization features from a mntner object.

cert:        [mandatory]  [single]     [primary/look-up key]    
address:     [mandatory]  [multiple]   [ ]                      
phone:       [optional]   [multiple]   [ ]                      
fax-no:      [optional]   [multiple]   [ ]                      
e-mail:      [mandatory]  [multiple]   [look-up key]            
admin-c:     [mandatory]  [multiple]   [inverse key]            
tech-c:      [mandatory]  [multiple]   [inverse key]            
upd-to:      [mandatory]  [multiple]   [inverse
key]                      
mnt-nfy:     [optional]   [multiple]   [ ]                      
auth:        [mandatory]  [multiple]   [ ]                      
remarks:     [optional]   [multiple]   [ ]                      
notify:      [optional]   [multiple]   [inverse key]            
mnt-by:      [mandatory]  [multiple]   [inverse key]            
changed:     [mandatory]  [multiple]   [ ]                      
source:      [mandatory]  [single]     [ ]                      

The auth attribute points to a key-cert object.

Referencing a cert object
-------------------------

The object can be referenced from inetnum, inet6num, route (route6)
objects by using cert-c attribute.

While updating an objects with this attribute the authorization checks
specified in the auth attribute of a referenced cert object should be
passed.

CERT related queries
--------------------

Typical use case is to find CERT contacts provided that IP
address/prefix of the abuser/source of an attack/etc. is known.

Possible scenario could be:
- the database finds the smallest less specific inetnum/route which
contains cert attribute starting from the exact match.
- result of the query is inetnum/route object, cert object and key-cert
object.

A new query could be defined (-c in the example below that will trigger
such IP/CERT lookups)

$ whois -c 194.85.160.0
inetnum:     194.0.0.0 - 194.255.255.255
netname:     EU-ZZ-194
descr:       European Regional Registry
descr:       Europe
country:     EU
admin-c:     NN32-RIPE
tech-c:      CREW-RIPE
tech-c:      OPS4-RIPE
