Best way to block porn? via hardware is ideal

KyzenKyzen Registered User regular
edited January 2007 in Help / Advice Forum
Quick story:
My parents have some very religious neighbors, with a few kids. I was over at my parents house for dinner last night, and these neighbors were there. The big topic of conversation at the table for some reason was the fact that the neighbors kids (ages 9, 12, and 15) were caught looking up porn yesterday. My parents of course immediately suggested that I could help them block this. I was about to say I was too busy with work (otherwise known as The Burning Crusade ;) ) when the neighbor mom said that that would be so sweet of me, and they'd be willing to pay me $50 an hour if I could get it done for them in under 6 hours.

So I agreed. I went over there, and they have a simple Linksys router, a WRT54GSv6. I tried the basic content filtering, and found I can block some sites directly, and others via keywords, but it is not even close to being a suitable filter, since I managed to find porn in less than 2 minutes of trying simple searches.

I asked what their budget was for hardware and/or software, and they said $250, give or take a little. Obviously the cheaper the better, and they hinted that if I kept it under $250, they'd give me part of the difference.

I have no idea why they're willing to pay so much to block porn, but whatever. It's going to pay for the deposit on my new apartment when I move :)

So, what I need:
-A high quality way to block porn, and other questionable content (bomb making came up :roll: ). Porn is most important though.
-A hardware solution is ideal. Is there any sort of firewall-type-box that can be stuck between the computers and the interwebs to filter traffic as it comes/goes? They've already said they don't care if it has a slight impact on their net speeds; all the adults use the internet for email and news, the kids play some games, but the parents feel they brought any punishment upon themselves.
-A software solution would be fine, but I worry that the (incredibly bright) kids would eventually find a way around it. Plus I'd feel bad cluttering up their machines with crap that would have a hugely negative impact on their speeds.
-The more user-friendly the GUI the better, as the parents want me to show them how to use it once it's set up.

Any suggestions?

    Yeah I'm not expecting a 100% success rate here. I think they'd be happy if it just took a lot more effort to block porn.

    I suggested taking the computer out of the kids rooms, but that's apparently not an option, because they want their kids exposed to technology or something like that.

    At the moment, software wise, I'm looking at NetNanny and Cyberpatrol.

    I don't think this exists yet. If I were you, I'd talk to their kids, and offer them a cut of your profits to hide what they're doing better.

    Maybe talk them into getting Windows Vista? It has built in parental controls and account auditing. So, if they are trying to look at porn, the parents can find out and... uh.. hit them with a switch or whatever religious people do. You also wouldn't have to worry about bulky 3rd party software mucking things up.

    That all depends on how good their machine is though.

    Here's more on the parental controls vista offers

    You could look at a better hardware firewall appliance, that would give *better* filtering ... like sonicwall, etc ... not sure how cheaply they run.

    But then again, not even websense can totally block all porn .. as i can see a fair amount via GIS.

    They are using a linksys that can have new firmware downloaded to it. .. which gives better options then default..

    Either way .. you can educate the parents that you can only block by keyword, or by sites ouright. .. but you will never catch it all.. and in a fair amount of cases, block legit sites as well.

    This will become evident when one of the kids needs to write a report on breast cancer. Or the cockles of the heart.

    In a home workgroup, I don't know of a way to do it.

    Even on corporate networks with expensive programs that filter and block sites based upon a sites meta data, you can still access what they don't want you to in some way.

    Really, as far as I've seen websense is really good, but as mentioned earlier, you can still find porn if its on a site that doesn't "look" like a porn site.

    It's wierd to me that the parents care about their kids looking at porn, but don't want to monitor their childrens computer usage themselves directly. I know its not an answer, Just an observation.

    You're not going to find a software- or hardware-related way to stop it. The best option is to install a program that e-mails the parents reports on what sites the kids are visiting. Tell the kids that there are two or three of the programs on there doing it, and that the parents are alerted if they're uninstalled.

    Making them not want to go to porn sites on that computer is going to be your best bet.

    Or perhaps software that takes a screenshot at pre-determined intervals. Give each kid a unique login, and tell the parents to check the screenshot archive each week or so.

    Yeah, I was somewhere with porn blocking shit and it blocked/interfered with not porn related things. What a pain in the ass. I dunno how big of a concern this is...

    My parents didn't trust me with a comp in my room for the longest time. Then again, back at that time we only had one comp for the family. Silly parents wanting to expose their kids to technology.

    I'd second the keylogger/email to parents idea. I'm pretty sure they have hardware keyloggers that you'd plug the keyboard into as well.

    If you go a software/hardware route you WILL be blocking them out of legit pages as well.

    Add in whatever the router has, use some a program or 3 that will report to the parents whats going on. Tell the kids this is an unbeatable program that they cannot get past, and their parents will know whats what and all that jazz.

    Take the parents aside, and tell them that there is no surefire way to do this 100%, that their involvement would be somewhat neccessary, but you've supplied them the best they can reasonably expect

    I agree with everyone above that nothing will filter 100% and if it's really locked down then legit sites have a good chance of being blocked too.

    If the kids are aware that their parents _know_ what they are surfing, that should be a decent enough deterrent. If not, then parenting skills need to be applied and their internet should be revoked as punishment. They can have the computer in their room to be "explosed to technology" but the kids should understand that the net needs to be used within the rules set forth by the parents.

    I honestly feel sorry for the kids. A 15 year old would be bursting within a week, point out to the mother she'll have to wash the clothes he sleeps in more often.

    The best way is to instil the fear of god into them. Somehow permanently lock the box and convince them you've mounted the keyboard logger on the inside that only the parents can access, (or acutally do it, drill a hole in the box feed the usb cord through and set it up in there) combined with a email monitor.

    The system admin the HELL out of the kids logons (ie only let them launch programs, stop them access the history so they can delete in in firefox, IE (I know you can do this in IE not sure about firefox), and can you restrict if the can access the task manager?) and give the parents an actual password containing numbers and words that they don't choose. Then send it to switch user whenever the screen saver comes on which should be set to less than 2 minutes.

    Explain to the parents how to check through the kids recently opened directory (for pictures/movies the one in C:\Doc..Settings... etc) and possibly lock from the kids deleting it if you can, how to use apply a filter to check the key logging and how to scan through their history. They also need to realise now though that they need to install everything on the computer themselves.

    Or you know, they could always supervise their children.

    If the 15-year-old is halfway intelligent, he'll know that no program is unbeatable. Just install the one monitoring program, and maybe a keylogger. The parents don't even have to check the keylogger. Tell them that there are two or three programs in there, and that they send regular e-mails to the parents, so the parents know if the kids have uninstalled the programs. Also, lock down the parents' e-mail.

    Odds are, the parents don't even have to look, or care, as long as the kids think they do.

    This gets a lot easier if you restrict them

    I've never really messed with the hardware ones.

    Most of the software ones are easy to find and trick. Alot of them aren't even encrypted. it's not hard to open the character map and click out "www.somepornosite.com"

    Kids are alot more leet than most parents want to give them credit for. My mom recruited ME to find out why her keylogging software wasn't working, somehow expecting me to be sympathetic to lying spying and fostering distrust.

    I just asked my brother what the deal was, and he showed me his copy of DSL.

    There is a program called x3watch that monitors the sites that are accessed and emails an "accountability partner" at selected intervals. As far as I know it only works for IE, so restricted installs would be a must. There is a pro version as well taht is supposed to be quite a bit more robust than the freeware version and still very cheap.

    Actually we didn't look at the history until later. When I said they were caught looking at porn, I mean the parents walked into the eldest kids room and found him and the youngest with several dozen windows up (I'm sure most were popups).

    A white-list is sounding good as well, I suggested the logger to the parents and they believe it's damaging to their kids spiritual health to even see boobies, so they'd prefer to block as much of it as possible. They understand that we'd be lucky to block 75% of the sites (I explained that more are created daily). So at this point we're looking for a cheap way to white-list sites that can be applied to 3 computers.

    Anybody know the parental control abilities available on the major open-source firmwares for Linksys routers?

    Even if he doesn't install one, I'd advise him to tell the kids that he's got a program taking screenshots at random intervals, so that if they do try to screw around with the programs installed, the parents will see. That should at least deter them from trying, knowing that unless they crack it on their first try that their parents will 'see' that they were trying to.

    Dude, there's nothing he can do that they can't get around if they're determined. The idea is to make it as frustrating and unappealing to browse porn as possible, and a keylogger is a good step in that direction.

    Me? I like the idea of a whitelist the most. But i'm not sure what they're using it for anyway..

    Keyloggers aren't really defeatable by a 15 y/o n00b. But it seems more relevant to just log what sites people are visiting (i.e. links).

    What about something like netnanny? Isn't that a programmable whitelist? More expensive, though.

    If you do want to use a keylogger (in addition to blocking or whatever else), and you're worried about the 15 year old finding his way around it, a good idea would be to use two keyloggers. One easy to find, either crappy software or a hardware solution. The second harder to find (ie, software which is better at hiding itself). Then, depending on how much effort you want to put into this, you can either simply forward only the logs from the hard-to-find one to the parents, or (more effort) forward both and set up a simple program to present the differences between the two logs.

    I find that really problematic (not to mention weird, my parents fundie religion encourages all computers to be located in a public part of the house to keep a lid on shenanigans). If they're not willing to actually parent their kids, it is inevitable that they'll get around whatever you install - and you'll be blamed for not doing a good enough job. I think whitlelisting and proper popup blockers (and AdBlock with a decent filter) should protect the kids while still preventing valuable info like medical stuff from being blocked*, but you need to emphasise to the parents that there is no substitute for supervision. Point out that its about caring, blah blah, they should get the message.



    *please try and avoid blocking health resources along with porn, particularly stuff on reproductive health. Children from very religious households often receive minimal support and education on things they actually need to know about their bodies in order to be safe and feel unable to communicate with their family about their needs. They often leave reproductive problems untreated (like infections) and are actually more likely to engage in high-risk sexual behaviours as a result. ALso, you don't want to prevent the parents from being able to access medical info either.

    Seconded. I believe the sex chat in our house consisted of some prolonged stammering and the idea that Jesus is watching you beat it.

    I suppose a kept URL history emailed at random intervals to the parents is probably the way to go, as it forces the kids to police themselves. Big Brother is certainly cost effective. It's good the parents are taking an interest, you can't have lil Johnny getting off in his room. Have to keep that to your best friend's sister's bathroom, yknow, where normal people go.

    I've had to set this stuff up before, and the best product I've come across is Cyberpatrol. The fact that it updates itself weekly for new sites to be blacklisted, etc, is great. It also monitors attempts to get into the controls or task kill it, etc. Also does all the reporting, etc. It'll even record browsing history without blocking, if you just want the threat without blocking potential helpful sites. Anyway, it's pretty reasonably priced, and I've been happy with it. Couple it with some group policy edits, and you can keep a tidy PC.
