This is a concern for any application logic that contains intellectual property that the author does not want to share with the world: while obviscation and minimization (white space removal, shortening identifier) can certainly render JavaScript much harder to read (and debug), developers should consider Ajax applications to be like HTML in that others will be able to examine the fruits of your labor.

• Use SSL/TLS (i.e., HTTPS) – In addition to protecting the privacy/integrity XML/JSON HTTP communications to/from the Ajax client, SSL/TLS encryption limits access to the Ajax source code itself to only those that have legitimate log-ins (as per above), since no-one snooping on the network can see the app.

For most Ajax applications, simply maintaining a strict separation of code from data (and never interpretting JavaScript that is included within user data) protects against such attacks. s r.o.

This means the Ajax server can act as a secure, proxy gateway for accessing intranet applications, and can govern which external web services (if any) are accessible for mash-up within the Ajax client. Zimbra recommends only deploying Zimlets that have been certified by Zimbra or else which have been vetted by your security architects internally.

So, while making the Jquery Ajax with Authorization Headers - jQuery Forum • No server-side interpretation of JavaScript or other client-submitted code – Zimbra receives vanilla XML requests from the browser client that are validated and then processed by Zimbra server-side Java code. The end result is that while an attacker with appropriate security credentials (such as a user’s password) could certainly damage that user’s server-side data, there is no way for them to compromise other user’s data or the server in general. I have downloaded the utility but when I try to run it, I get the following message from Windows: "These files can't be opened" "Your Internet security settings prevented one or more files from being opened." • Limited or no client-side interpretation of JavaScript within user data – The Zimbra Ajax client is, of course, an Email application that runs within the confines of the web browser. It is new technique used to create better, faster and more interactive web systems or applications. Thank you for subscribing to the Zimbra Newsletter.

• Server-side control of intranet and Internet mash-ups – Zimlets and other Ajax mash-ups are precluded from accessing arbitrary services on the Internet (unless they open a new iFrame, which can be determined at server deployment time), and must instead (like Java applets) make all invocations back to the originating server (in our case, the Zimbra server). All this is not an issue for the Zimbra Ajax Client, since it is, after all, open source.
FOLLOW @HFXforum ON TWITTER. The only real alternative is to either (1) limit log-in to the application to trusted users/partners (in this way only licensed/authorized users get to download the Ajax application logic); or else (2) keep closely-held algorithms on the server-side, and simply invoke them via web services from the Ajax client.

ajax ; ajax Members. To continue the Zimbra blog series on Ajax (recent entries include Ajax innovation is about the server, Ajax optimization techniques (presented at OSCON), OpenAjax update, and Ajax’s impact on scaling), we wanted to offer some general thoughts on securing Ajax applications gleaned, of course, from our Zimbra experience. Ajax is abbreviated as Asynchronous Javascript and XML.
Ajax - Free source code and tutorials for Software developers and Architects. Zimbra blocks any “risky” HTML, first on the server and then again (for extra protection) on the client.
The most obvious security issue for Ajax applications is that the associated source code is inherently downloaded to the browser for interpretation. No JavaScript flows from client to server, and there is no server-side interpretation of any application data (e.g., message bodies). Dan Connole, Founder and President: Dan founded the NCRSF shortly after the formation of the Department of Homeland Security to create a forum for industry partners to collaborate in the federal security market. Yes, I did restore the zone settings as shown. The most obvious security issue for Ajax applications is that the associated source code is inherently downloaded to the browser for interpretation. Powered by Invision Community. Zimbra provides the following additional guarantees to further secure Zimbra deployments over even public networks, techniques that we beileve are broadly relevant for securing Ajax applications: • Dynamic Ajax client download – Ajax client code is downloaded on demand from the trusted server after a particular user logs-in, automatically ensuring client and server versions are in-sync (for public computers, a shift re-load is better in that it overwrites any Ajax code from that website leftover in the browser cache).
Ajax security advantages. • Mash-ups/Zimlet validation – Zimbra’s mash-up architecture does provide the opportunity to introduce server-side Java code (most Zimlets run only on the client side), but the introduction of Zimlets requires server administration privileges.
(hint hint, best to assume they CAN see you!
When a rich HTML message contains any suspect JavaScript, simply better to err on the side of caution.
