Registration Control
About Allow and Deny Lists
When an endpoint attempts to register with
the VCS it presents a list of aliases. You can
control which endpoints are allowed to register
by setting the
Restriction Policy
to
AllowList
or
DenyList
and then including any one of the
endpoint’s aliases on the Allow List or the Deny
list as appropriate. Each list can contain up
to 2,500 entries. When an endpoint attempts
to register, each of its aliases is compared
with the patterns in the relevant list to see if
it matches. Only one of the aliases needs to
appear in the Allow List or the Deny List for the
registration to be allowed or denied.
For example, If the Registration Restriction
policy is set to
DenyList
and an endpoint
attempts to register using three aliases, one of
which matches a pattern on the Deny list, that
endpoint’s registration will be denied. Likewise,
if the Registration Restriction policy is set to
AllowList
, only one of the endpoint’s aliases
needs to match a pattern on the Allow list for it
to be allowed to register using all its aliases.
Patterns and Pattern Types
Entries on the Allow List and Deny List are a
combination of Pattern and Type. The
Pattern
specifies the string to be matched; the
Type
determines whether that string;
must match the Pattern exactly (
•
Exact
)
must appear at the start of the alias (
•
Prefix
)
must appear at the end of the alias (
•
Suffix
)
is in the form of a Regular Expression
•
(
Regex
).
Allow and Deny Lists
Restriction policy
Specifies the policy to be used when determining which endpoints may register with the VCS.
None
: Any endpoint may register.
AllowList
: Only those endpoints with an alias that matches an entry in the Allow List may register.
DenyList
: All endpoints may register, unless they match an entry on the Deny List.
The default is
None
.
