Has Corporate Info Security Gotten Out of Hand?

KoshClassic asks: "What is the right balance between security and productivity, in the corporate IT environment? Looking back at my company, 10 years ago, our machines were connected directly to the Internet, no proxy, no firewall, no antivirus software. Today, my company's proxy server blocks access to: 'bad' web sites (such as Google Groups; our 'antivirus' software prevents our machines (even machines that host production applications) from carrying out legitimate functions, such as the sending of email via SMTP; and individual employees are forced to apply security patches with little or no notice, under threat of their machines loosing network access, if they do not comply by the deadline. On one hand, you can never be too secure, however on the other hand, have we become so secure that we're stifling our own ability to get things done? What is the situation like at other companies?"

Hmmm, but my machine is a linux machine! [...] Hmmmm, but my machine is a linux machine! [...] Fortunately I had a dual-boot, so I was able to comply.

Yeah, weird that they might want a machine running Windows XP to be updated. You might have Linux on the machine, but you also had Windows XP, and it sounds like it was missing security patches.

And, for the record, my assigned work had no specific XP requirement, and my responsibilities were heavily around Unix.

And you apparently had a machine with Windows XP missing some (possibly significant) security patches sitting on their network.

I fail to see how this was stupid of the network admins. Draconian maybe, but it got you to apply the security patches.

Disclaimer: I work on the security team for a rather large (Fortune 5) corporation.

I would say, compare the environment of the public internet to how it was ten years ago. Would you place your unpatched Windows machine directly on the public internet now? You have (roughly) ten minutes before another infected machine exploits one of the dozen out-of-the-box vulnerabilities that will allow them to run anything it wants on your PC. Not the case ten years ago.

Unfortunately, what was once a rather quiet suburb filled with geeks posting to Usenet and using Mosaic is now a post-nuclear, disease filled demilitarized zone where so many infected systems simply sit and try to infect others that a defenseless machine (or a network of them) is doomed.

Trying to manage security in this environment is a much more difficult job than it ever has been, and every month that goes by makes it more difficult. We shudder on the second Tuesday of every month at what new terrifying vulnerability Microsoft will tell us is in their product that's deployed on a hundred thousand machines on our network. We plead with other IT teams (networking, server admins, client admins) to implement our tools and software and protect the environment, but most of them get pushed to the back burner, either because it's "too invasive", i.e. it annoys the end user too much; or it costs too much; or they just don't have the time.

Then MS05-039 is released. We plead and plead for the patches to be distributed right away because of how severe the threat is. But users like the submitter can't stand to have their PC rebooted unless it's the absolute perfect time. Plus, we have 1700+ applications to test compatibility with the patch on, on hundreds of different PC environments. And it requires a service pack we don't have deployed everywhere, again, because it's too invasive.

Then Zotob.E gets into the environment, and shuts down large sites in a matter of minutes. Then people scream even louder! Where is security? Why didn't they prevent this?

Because no one takes security seriously until it's too late.

From a security admin's perspective, we never have enough resources or management support to fully defend against even the most prevalent threats. Because security (and, as most admins know, IT in general) is underfunded. Because of (very real) scenarios like I described above, we have much more support than we did, and things are improving.

I guess my point is, step into our shoes for a few days. We don't enjoy being draconian - we like Google Groups as much as anyone else! But there are so many attack vectors that we have to be concerned about to protect the environment - and it only takes one. One of my co-workers is fond of the saying, "the hackers only have to be lucky once - you have to be lucky all of the time."

I guarantee every IT admin reading this is thinking, well, if you did this instead of that, if you had two hundred guys on your security team, with all of them testing patches, while listening to every end user complaint and rectifying their situation immediately, you could stay out of the end-user's way! Trust me - we know. We wish our teams were as stacked as they should be. Heck, we wish it wasn't necessary at all to have to defend against stuff like WMF, where any end-user clicking on a link from their IM buddy could get exploited in a second... we wish it wasn't like this. We wish things could go back to how they were ten years ago. The reality is, this is the internet we built and we are fighting to protect our assets from.
