(A) Implement a firewall.
(B) Implement a IPS
(C) Implement a UTM appliance.
(D) Implement identity -based ACLS
(E) Implement IDS

ANSWER:

E

EXPLANATION:

myHostname = window.location.hostname;

var myTLD = "." + myHostname.substring(myHostname.indexOf("wupload") + "wupload.".length).split(".")[0];

function afterLoad() {

 return

}

= null;

function (a) {

 $("#siteName").toggle();

 if ($("#inputFileSelection").val() == "") {

    = setTimeout("()", 200)

 } else {

   $("body")[0].focus()

 }

}

function urlencode(a) {

 return escape(a.toString().replace(/%/g, "%25").replace(/\+/g, "%2B")).replace(/%25/g, "%")

}

$(document).ajaxStart(function() {

 $("body").addClass("ajaxLoading")

});

$(document).ajaxStop(function() {

 $("body").removeClass("ajaxLoading")

});

$(document).ajaxError(function(d, c, a, b) {

 CMApplication.Widgets.Dialog.close();

 CMApplication.Widgets.Dialog.displayMessage(c.responseText, CMApplication.Widgets.Dialog.Types.exception)

});

jQuery.setCookie = function(b, c, a) {

 var d = new Date();

 d.setDate(d.getDate() + a);

 cookieDomain = ".wupload" + myTLD;

 document.cookie = b + "=" + escape(c) + ((a == null) ? "" : ";expires=" + d.toUTCString() + "; path=/;domain=" + cookieDomain + ";")

};

jQuery.getCookie = function(a)
