4.3 Access Control Entries
An Access Control Entry (ACE) is a filter applied to the X.509
digital certificates used to authenticate connections over a
network. An ordered set of Access Control Entries, each with
an associated allow/deny action, comprises an Access Control
List (ACL), as used by three possible Mesh Point functions:
IPsec - as described in Section 4.4.5
internal RADIUS - as described in Section 4.5.2.7
ES210 Radio STA Interface - as described in Section
3.4.11.12
A given ACE can be specified simultaneously for IPsec and
internal RADIUS ACLs. (An ES210 in Station Mode must be
dedicated to that function.)
ACEs are prioritized per ACL. The action to be taken when an
ACE applies to an X.509 certificate is configured per instance
of the ACE in each ACL that includes it.
Each ACE must be uniquely named. Each must provide at
least one value against which to match X.509 certificates and
can apply up to three filter criteria.
Use
add ace to configure ACEs on the Mesh Point:
# add ace -name
<ACEname>
-pattern
<DNpattern>
-keyusage digitalsignature,keyagreement
-extkeyusage
tlsserver,tlsclient
Name identifies the ACE in the Mesh Point configuration. You
will use this name to add the ACE to one or more Access
Control Lists, as mentioned above.
Pattern specifies the pattern against which X.500
Distinguished Names (DNs) in X.509 certificates will be
matched. Each Relative Distinguished Name (RDN) in the
certificate DN is compared, in order, to the corresponding RDN
subpattern specified by the ACE. You can use an asterisk (
*)
as a wildcard character in RDN subpatterns.
For example, the distinguished name:
/O=Fortress Technologies/OU=Engineering/CN=John Doe
is composed of three RDNs. In addition to exact matches, the
Distinguished Name pattern can match one or more of the
component RDNs using one or more wildcard characters. All of
the following subpatterns will match
/O=Fortress Technologies:
/O=Fortress Technologies - matches exactly.
/O=* - matches any string.
/O=*Technologies - matches any string ending in
Technologies”.
