Experts are taking issue to a recent study which warned users of potential risk of using Firefox

A recent security study from Bit9 argued that Mozilla's Firefox was the most vulnerable application and thus a major threat to businesses.  One of the chief reasons it gave was the lack of a large-network patching system.  For this reason, despite recent security flaws, it did not consider Microsoft's Internet Explorer software, as it assumed that such a patching system dramatically lowered vulnerability.

Bit9 went as far as to suggest that enterprises block their employees from having access to Firefox and delete it from work computers.

Some firms, including Mozilla, were quick to take issue with Bit9's alarming comments.  Representatives from Mozilla's security branch, Human Shield contacted DailyTech with remarks on the topic.  The company's Johnathan Nightingale states, "While we're always happy to see stories that focus on educating our users about security, there are some problems with Bit9's methodology that hinder its ability to draw any meaningful conclusions."

According to Mr. Nightingale, by raising the "risk" of companies which disclose critical vulnerabilities, Bit9's study punishes openness, a critical key to security.  It rewards companies that keep their vulnerabilities secret, he argues.

He also criticizes Bit9's stance on patching, stating that the firm's claims fall short of reality.  He states, "Bit9 seems to understand (the need for smarter metrics) in its focus on application support for updates, but again it fails to account for the real world experience. Firefox does not deliver WSUS updates, but our built-in update mechanism requires no user intervention, and we consistently see 90% adoption within six days of a new update being released."

He concludes, "The Firefox vulnerabilities Bit9 discusses are long-since fixed, with the majority of these fixes coming within days of it being announced. That is the real measure of application security: are known vulnerabilities fixed promptly, tested carefully, and deployed thoroughly? Bug counting is unfortunately common because it's easy, but it should not be a substitute for real security measurement."

Similar sentiments were also echoed by various readers on DailyTech as well as several sources in the security business.  While the Bit9 study certainly takes a controversial and interesting position, according to many its claims are overly broad and flawed.  Whether this is the case is largely a matter of opinion, but one thing's for sure -- whether you're on Firefox, Opera, Chrome, or Internet Explorer, security is largely in the hands of the user.

You gotta admit, Bit9's timing couldn't have been worse! Zero day IE exploit that took days for Microsoft to patch, and presumably is still unpatched in many companies *because* of the ability for business to enforce the roll-out at their end instead of Firefox's centralised means. This type of rollout management is great - for certain applications. Not a frickin' web browser. And I don't care that retards wrote IE6 only web apps; they're not web apps, they're IE6apps. You reap what you sow.

Still getting Windows "Restart Now/Later" for this patch. It's a WEB BROWSER for the love of God, why should I have to reboot. Sheesh. Okay, it might be being used by other apps because it's also a UI component, but maybe they could work on a way to unload and reload the component without a reboot.

And what of companies that use web browsers to run business critical applications? The situation is far more complex than you make it out, and the centralized updates on FireFox can be a bad thing in these instances.

The real issue is the IT department. If they think there are no issues, than they shouldn't block users computers from auto-updating. If there may be a problem, than they should test it before implementing it.

Stop with the thinking that what works for you will also work for the other 99% of the world.

I feel like feeding the trolls ;)

So... do you want dos 1.0 support as well?
Or maybe the old IBM Mainframe should be supported... Or an abacus (I've seen it referred to as an ancient computer)...

Nah... FF should drop support for all stupid people and just support running on smart, intelligent people's brains.

Ok... that was fun... back to reality.

Well, as Big Al said, "Eat it... eat it...".

It's kind of pointless to reference non-GUI systems like DOS and MVS (of course, all new IBM "mainframes" run Unix as well as MVS, so it's hardly relevant to mention them at all, plus mainframes are all about processing data--not about providing browser support... you might as well take a tractor-trailer to Indianapolis or Sebring). The real point is that Bit9 is, well, kind of stupid.

It took me a few seconds to figure out if he was joking.. then I looked at the poster and everything made sense..

PCDOS never supported IE.. Netscape.. or any other mainstream browser..

The best it has to offer is Arachne

Then maybe those companies should do the semi-intelligent thing and 1) install firefox by default on all office PCs and Laptops and 2) TURN OFF AUTOMATIC UPDATES.

Goodness, you'd think this was rocket science. Whatever happened to common sense?

AFAIK, FF lacks the ability for IT groups to centrally change a setting like that, right?

Yes, and no. FF doesn't have anything built-in to centrally manage it, but it's easy enough to push such settings to a client. Likewise for FF updates. Since the updates can be pushed from a central server, they can run as administrator so the user does not need any administrative access.

Then, there is this customized version of FF that allows management via AD.

FF and most/all the other apps mentioned in the Bit9 list can easily be managed centrally, all you have to do is spend a few minutes on google to find how how.

The Bit9 "analysis" is completely meaningless.

I still don't understand why companies don't use FF as their preferred browser. Except for those that do have IE6 apps. Other than that is sheer stupidity, IMHO

This is what my department is doing.

1. They are actively updating the firewall to block the bad sites.
2. The IE patch is being rolled out via SMS after testing.
3. The AV is being updated as soon as an update is available.
4. Monitoring for the signature on the network.
5. And more that I'm not aware of.

All this happens within 30 days of the patch being released. It looks like a big window, bit there is a lot of testing required.

They are even considering using FireFox in the not too distant future. The main concern is that 'Out of the box' FireFox does not support central updating - our internal network uses a distributed file system that reduces the overhead of distribution. All downloads are local to the user. Imagine 30k+ Firefox installations asking a single Internet connection to download the same file 30K+ times and you can see the problem.

The other concern is how to limit FF's ability to install add-ons. They want to manage and validate the add-ons before allowing them on the network, just like any other application.

Not sure if you can use this to manage updates, but it gives the ability to control Firefox via Active Directory. They also make a special Firefox Deployment program that lets you configure Firefox with certain extensions, addons and settings for easy installation across your entire network.

if you use an caching proxy that should not be an problem

with any large network if your using an caching proxy if alot of users do access the same page even if its thorough the day it can save lots of bandwidth

well add-on just block the addon server

there should be an add-on for group polices tho

Based on what I'm reading the Firefox's built-in update mechanism requires the browser to be running in administrator context.

This whole discussion appeared to aimed at enterprise use and management of browsers. Even Mozilla's response seemed to be geared towards this based on their reference to WSUS.

So... how does it make any sense for a representative of Mozilla to argue that their patching is superior when it relies on the browser running in admin context? That's simply assinine.

I thought the original article they were replying to was pretty weak, but that kind of response is even more pathetic to me.

Regarding your comments. I suspect you have no experience with enterprise desktop maintenance. The patches under security bulletin MS08-078 could easily be deployed to systems within hours using Microsoft's tools like WSUS. You provide no information at all to support your assertion that these deployment tools actually slow down deployments of these patches. In a large enterprise, the limiting factor is typically not the pace at which this can be deployed, but the change controll processes, communications, agreed testing window for internal applications, etc.

It should only require Admin if it was installed someplace the user does not have rights to, like say Program Files. We've had users who install FF themselves despite being 'limited' users, simply by changing the install point to their My Docs folder (XP SP2). I'm not certain, but I assume this would mean that updates function this way as well?

The patch released yesterday, and every computer at my workplace was patched by the morning.. I even came in to see that my computer had been restarted for me.

Apparently firefox, chrome and safari also all released patches yesterday, which makes one wonder if it was only IE7 that was affected.

Still getting Windows "Restart Now/Later" for this patch.
Internet Explorer components are used in Windows Explorer, which is probably the reason it is asking you to restart. Chances are you don't have to restart you computer completely, but merely logoff and log back in to restart the windows explorer shell.
