Introduction
This document provides a sample configuration on how to apply a rule so that the Cisco ASA will check the first three characters of the
hostname before establishing the SSL connection.
Resolution
Here is the expression that you need to add on the DAP policy in order to establish the connection, based on the first three characters of the hostname.
assert(function()
local match_pattern = "^[Mm][Ss][Vv]"
local match_value = endpoint.device.hostname
if (type(match_value) == "string") then
if (string.find(match_value, match_pattern) ~= nil) then
return true
end
elseif (type(match_value) == "table") then
local k,v
for k,v in pairs(match_value) do
if (string.find(v, match_pattern) ~= nil) then
return true
end
end
end
return false
end)()
