Security Rules

We have seen how the module works on the concept of rules and how to declare them. Before we dig deeper and decompose the rules let's have a look at the processing of the rules first.
Rule Anatomy
Each rule is modeled by a struct with keys in it:
{
    "whitelist"     : "", 
    "securelist"    : "", 
    "match"            : "event",  // or url
    "roles"            : "", 
    "permissions"    : "", 
    "redirect"         : "", 
    "overrideEvent"    : "", 
    "useSSL"        : false, 
    "action"        : "redirect", // or override 
    "module"        : ""
};
The only required key is the secureList which is what you are trying to secure. The rest are optional and described below. Please note that you can add as many keys as you like to your security rules, which can contain much more context and information for the validators to use for validation.
Please remember that by default the secure and white lists are evaluated as regular expressions. You can turn that off in your configuration settings.​
Rules processing
When processing rules, it is important to realize these rules come as an array which will be processed in order, so make sure your more specific rules will be processed before the more generic ones.

Rule Elements
Property
Type
Description
match
event or URL
Determines if it needs to match the incoming URL or the incoming event. By default it matches the incoming event.
whitelist
varchar
A comma delimited list of events or regex patterns to whitelist or to bypass security on if a match is made on the secureList
securelist
varchar
A comma delimited list of events or regex patterns to secure
roles
varchar
A comma delimited list of roles that can access these secure events
permissions
varchar
A comma delimited list of permissions that can access these secure events
redirect
varchar
An event or route to redirect if the user is not authenticated or authorized
overrideEvent
varchar
The event to override using ColdBox's event.overrideEvent() if the user if not authenticated or authorized
useSSL
Boolean
If true, force SSL, else use whatever the request protocol is
action
string
The action to use (redirect or override) when no explicit overrideEvent or redirect elements are defined.  If not set, then we use the global settings.
Rule Overrides
As we saw from the overview and our configuration sections. We can declare the default actions for authorizations and authentication issues and to which events/URLs to go if that happens. There can be a time where you can override those global/module settings directly within a rule. Let's explore those overrides:
Redirect
If you add a redirect element, then you will be explicitly overriding the global/module setting and if a match is made a redirect will occur.
{
    "secureList" : "*",
    "redirect" : "mysecret.event"
}
OverrideEvent
If you add an overrideEvent element, then you will be explicitly overriding the global/module setting and an event override will occur.
{
    "secureList" : "*",
    "overrideEvent" : "main.onInvalidEvent"
}
Action
If you add a action element, then you will be explicitly overriding the global/module setting and the action will be based on this value (override or event)
{
    "secureList" : "^api.*",
    "action" : "override"
}
White Lists
If a rule has a white list, then it means that you can declare what are the exceptions to ALLOW if the incoming URL/event was matched against the securedList. This is a great way to say, hey secure all but allow the following events:
{
    "secureList" : ".*",
    "whitelist : "^login"
}
Please note: if a rule has a whiteList, it only applies to the current rule. So if the whitelist matches, it the current rule is skipped and the process continues to the next rule.
Sometimes you want to make sure ALL events are secured, except for the ones specified, such as login events. If you add new functionality to your app it is easy to forget a new rule. To prevent unwanted access you could specify a LAST rule, which matches ALL event but NO permission at all. In that case you have to add a whitelist for all events which should still pass, for example:
{
    "secureList" : ".*",
    "whitelist" : "login",
    "permissions" : "nonExistingPermission"
}
