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
).
