Raxxon asks: "We (my business partner and I) were asked by a local company to help 'tighten up' their security. After looking at a few things we ran some options by the owner and he asked that we attempt to block access to MySpace. He cited reasons of wasted work time as well as some of the nightmare stories about spyware/viruses/etc. Work began and the more I dig into the subject the worse things look. You can block the 19 or 20 Class C Address Blocks that MySpace has, but then you get into problems of sites like "MySpace Bypass" and other such sites that allow you to bypass most of the filtering that's done. Other than becoming rather invasive (like installing Squid with customized screening setups) is there a way to effectively block MySpace from being accessed at a business? What about at home for those who would like to keep their kids off of it? If a dedicated web cache/proxy system is needed how do you prevent things like SSL enabled Proxy sites (denying MySpace but allowing any potentially 'legal' aspects)? In the end is it worth it compared to just adopting an Acceptable Use Policy that states that going to MySpace can lead to eventual dismissal from your job?"

The 2nd best way is random incomplete blocking...

Nonetheless, the best solution that I came up with (I don't think I "invented" this, but I did come up with it after many days of contemplating) was to have a revolving DNS change for those 20 MySpace Class C addresses. We made it intermittent enough that the employees "thought" it was MySpace downtime, and eventually usage dropped significantly. Every 5-10 minutes a CRON job would add its own random address for one of the MySpace addresses, then 5 minutes later it cleared that and then did it to another address.
The only guy that I am aware of that noticed it is the guy who ran his own DNS on his workstation, but he was geeky enough to probably realize that it wasn't MySpace that wasn't resolving.
I still think that it is wiser to discuss WHY employees might be needing some downtime versus locking them out of applications. Happy employees are efficient, productive and fun to work with. I would never block my employees access to any sites (then again, I would never drug test, delve into their private lives, run a credit report, or any of the usual steps employers take).

I have no mod points, but I'm modding you up in spirit.
<soapbox>
I absolutely cannot stand it when employers filter content. The thing is, even if people are wasting too much time at work browsing MySpace (or the Internet in general), that is a management problem, not a technical one. If you take away their MySpace or whatever it is they're browsing, they're just going to move on and browse some other site. If you put a whitelist in place, they'll just find some other way to goof off. The problem isn't that the Internet is distracting, it's that the employee is easily distracted.
I work at a big company as a contractor. It just recently blocked access to the big Internet e-mail services (Gmail, Yahoo Mail, etc.) because it didn't like employees wasting time with their personal e-mail at work. Of course, being a contractor, it doesn't take into account that I use my personal e-mail to communicate with my contract agency about stuff that I'd rather not have stored on company e-mail servers. It's easy to say, "Well, you shouldn't use company resources for that type of stuff," but practically speaking, my ability to communicate effectively with my contract agency is essential to me doing a good job for them. It also totally ignores the fact that I keep personal stuff like vacations and such on my personal Gmail calendar to know when I should ask for time off, when my coworker's birthday is, and so on.
The company spends a fortune on content filtering. There's the hardware itself, the update service, the support contract, the personnel cost for the guy who maintains it, the internal support costs of handling trouble tickets related to it, the cost of Internet downtime due to it periodically failing, the cost of packaging the software end of it and deploying it to the workstations (so that you can't browse them at home on your laptop, of course!), and so on ad nauseum. Just as one example, some of our customers are casinos. So we can't just put a rule in that says, "block gambling sites," because our marketing and sales folks have to be able to access their sites. No, we have to have rules that say things like, "This group can access these sites, that group can access those sites, everyone else can't access any of the sites, ..."
Even in the extreme case of porn sites, the answer to controlling it is to make a company policy prohibiting browsing them, and if you catch someone doing it, fire them for it. If you try to block them all, you're just setting yourself up for someone saying something like, "Well, it wasn't blocked, so I thought it was okay to go there!" I've found that if you treat people like 12-year-olds, they tend to not disappoint you. When policies like this go into place, you're also going to have the contingent of people who deliberately goof off more as a form of passive-aggressive rebellion. It's just stupid, you're only causing more problems, and there's no need.
I know that some of you will probably reply, "But you have to filter content to avoid sexual harassment lawsuits!" No, you don't. As long as you make a company policy about it and you take the appropriate action when someone breaks that policy, you'll win any lawsuit that someone may file. The law does not require you to spend a fortune to be a babysitter, it only requires that you take reasonable action to prevent a hostile work environment. The reason we have content filtering in the first place is because managers, in general, are lazy and don't want to do it themselves. The people who would sue you for not content filtering will sue you anyway. The only important thing is whether or not you'll win. Besides, at my company, the cost of defending itself against such frivolous lawsuits is negligible compared to the cost of maintaining our content filtering services.

If you want to block against proxies, use SquidGuard plus some blacklists. The ones at urlblacklist [urlblacklist.org] are good, as is the isakurldb [gplindustries.com] list (it's based on dmoz). Another one is the one from shalla.de [shalla.de]. All have social networking categories as well as proxy sites, though shalla's proxy and spyware lists tend to overblock.
I'd recommend merging urlblacklist's lists with isakurldb, and also shalla (but remove yimg.com from the redirector list manually) for both proxy and social networking. Then use SquidGuard to restrict the access.

(Score:1)(Last Journal: Monday September 11, @07:26AM)
By developing an 'acceptable use' policy you can define unequivocably the sites that an employee is allowed to access while in normal working hours. Rather than blocking any content, it's better to log all accesses through a pass-through proxy or some other mechanism. This way you can screen the users and see their adherance to policy, flag those for follow up and arrange time to discuss their opportunities for change. The real truth in IT management is that it must be mandated from the top down. If 'the powers that be' define a policy limiting company resource use, then it's easier to track than to prevent. Having all users reminded at each log on of their duties and responsibilities with respect to network access is also trivial and given such daily notices they would have little wiggle room with an 'I didn't know that was wrong.' defense. In the short term, you'll experience a small amount of pain with the unlimited access, but with a sound policy, you'll soon be reaping the benefits with lower administration times.
Failing that being workable, it's always best to 'deny all' and whitelist the sites that are acceptable, further containment of this concept is possible by group restrictions. This method would allow you to tune internet access by employee type(s) giving unfettered access to R&D but limit access to clerical who may just be spinning their productivity away on a myspace romp.
It's important to remember that these network services are paid for company assets, and the disposition of assets REQUIRES policy.

There was a small wooden fence around an area containing the moat and some potential dangerous ruined stonework.
I said: "what is the point of that fence, it's tiny, I could climb over it easily? it really doesn't do anything to stop me ending up in the moat"
They said: "well, the thing with fences is that they're not there to stop you getting somewhere. They're there to make you KNOW that you're not supposed to go somewhere. If you just fell into the moat, the castle owners are in trouble. If you climb over a fence and fall in the moat, the castle owners can say, 'well, come on, he climbed over the fence that clearly marked that area off limits. You can hardly blame us, and he can hardly claim he didn't realise he wasn't supposed to be going into that area'."
Likewise with your problem.
Yes, technical measures can always be defeated by the determined myspacer, such as via a proxy. However, I would say some technical measures are worth considering hand-in-hand with the AUP, as a sort of 'fence'. If myspace is banned by the AUP, but not blocked, then everyone will go there, and when they do, they can claim they didn't realise it was against the AUP, or they clicked a link which took them to myspace without realising that's where the link led, "honestly"... etc, etc.
If myspace is blocked, on the other hand, then you force people to "climb over the fence". Yes, they can still get to it via a proxy - but the fact they've gone to it via a proxy means it is explicitly, unarguably obvious that they knew they weren't supposed to be going there, and deliberately went out of their way to get around the rules. This, imho, means you will be able to enforce the AUP more stringently.

I would recommend against even trying to completely block it for employees. Having a policy to deal with major offenders is better than creating such a restrictive environment.
Firstly, the virus/adware problem the employer is worried about would be better solved by making sure the machines have up-to-date virus definitions, that the browser is configured properly: disabled Active-X, blocking popups, to not be Internet Explorer... the usual suggestions. Make sure their IT people are keeping the machines in order, and that the employees can't disable or otherwise futz up the antivirus software. And secondly:--
This makes me think of what happens when a government tries to outlaw something they know that people want: all it ends up doing is creating a new black market and more crime; beyond the tautology of new law = new lawbreakers, you end up with people doing all sorts of bad things they otherwise wouldn't have to do, just in order to get around a law that shouldn't've been passed in the first place. You start out by outlawing something you think people ought not have, and pretty soon you find yourself spending $40 billion a year with no end in sight, just to use one example [drugpolicy.org].
So right now they've employees wasting a little time each day on MySpace. Do you want to create a situation where instead some of these employees waste an hour or two trying to come up with creative ways to evade proxies and firewalls? Or where an employee ends up infecting his computer with all sorts of malware because of some shady site he came across while trying to find, say, open proxy lists? Or he ends up accidentally divulging a whole bunch of private data by setting his browser to use an open proxy, not realizing all his HTTP traffic is now being routed through who-knows-what in Russia? And how much productivity will be lost when some employee gets fired over 15min of slacking off and it takes the company two weeks to find a replacement candidate?
And consider the morale impact -- and thus productivity impact -- when you start getting employees grumbling about being treated like prisoners at their workplace.
I'd recommend that the employer A) not worry about the employees who spend a few minutes a day browsing MySpace, and B) only come down on the people having major productivity issues because they're spending half their day slacking off, or the people who've caused severe security problems by getting their computers breached by malware.

Put the strings into DansGuardian's banned phrase lists, and voila - blocked no matter what proxy is used.
Obviously this will not work for SSL encrypting proxies, however only a lunatic would allow a free SSL proxy meaning that SSL proxies are usually pay services, and are easy to spot if you look in your logs. Use SARG regularly to monitor access and you will easily see how your users are finding a way to it if they manage that in the future. Also set up a block page where your users can ask for sites to be unblocked - when the regular 'PLZ UNBLOCK MYSPAZ KTHXBY' messages stop arriving, be suspicious and look for how they are getting to it and take appropriate action.

If the job gets done, well and on time - then stop bitching about people surfing. Being productive for 8 hrs straight (short of 1 hr for lunch) is a utopia many employers dream of, especially if it has to do with doing the same task(concept) repetitively. You never get a different result by doing the same thing, so naturally, you will eventually get bored, whether you're a programmer, analyst, whatever....
If someone, on the other hand, provably surfs the net (check your company's network logs, you do have them, no?) so much so that his performance is consistently impeded by his, at this point, internet addiction - then apply your company's disciplinary policy appropriately (you do have policies too, no?).
Blanket statements like "web surfing impedes productivity" and designing unrefined policies around such statements can only discourage/anatgonize productive employees who are able to surf as well as work productively, if they happen to ever get caught in the HR policies net. Most office space/white collar computer-related type of work can get incredibly boring. Whether management likes to look good by appearing curt and managerial and reprimanding everyone for anything slightly in violation of the policy, or be relaxed and only deal with problems as they arise instead of being dickheaded about it, will set the tone, overall mood and atmosphere of the company you work for.
