Customizing MVC Action Filters

• Authorization - System.Web.MVC.IAuthorizationFilter
• Action- System.Web.MVC.IActionFilter
• OnActionExecuting 
• OnActionExecuted
• Result - System.Web.MVC.IResultFilter
• OnResultExecuting
• OnResultExecuted
• Exception - System.Web.MVC.IExceptionFilter
• OnException

While customizing the filter, we can define attribute usage
[AttributeUsage(AttributeTargets.Class | AttributeTargets.Method, AllowMultiple = false, Inherited = true)]

Once you create the custom filter, you need to register for it, You do this by adding them in the App_Start/FilterConfig.cs, in the RegisterGlobalFilters method:

filters.Add(new MyCustomAttribute());
