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?"
Security like most things, is a balancing act. Being able to manage the 'pain vs. protection' factor is the key to all of it, and unfortunately no tools seem to have the sliding adjustment with those options on it.
Ideally security will allow everything that's vital while not stepping on any services that are required. With most companies, what is 'required' ends up being pared down as the security net gets closed down tighter.
Nostalgia is one thing -- how many of us worked on systems that had telnet / ftp open to the outside without a firewall? I know I did back in the day. When management is behind security initiatives, being able to work on the business isses ("No, we CAN'T disable FTP!") becomes less of a problem.
Regarding individual workstations -- putting the burden on end-users doesn't seem to be a common (thankfully) configuration in the companies I've seen. Most larger places are doing automated patch management and deployment now. I know quite a few places where every single system (desktop and production) is patched within a 15 day window. While it's not bleeding edge, this relatively fast schedule combined with the concept of 'defense in depth' goes a long way to preventing issues. I know places that haven't lost a machine to a virus in YEARS.
Security that's preventing legitimate work from being done needs to be adjusted. All of the problems you've mentioned are fixable.
Being a corporate IT security at large corporation I can tell you why google groups are blocked. If I am looking at porn on alt.binaries.erotica and a female co-worker walks up behind me she could sue for sexual harassment and say the company did not take adequate measures to prevent this situation. Basically they fear a lawsuit.
