1 edit this page home | tags | site changes Soft security is not weak security. The idea is to protect the system and its users from harm, in gentle and unobtrusive ways. The opposite of HardSecurity. It follows NonViolence. Instead of using violence, it works architecturally in defense to convince people against attacking and to LimitDamage. It works socially in offense to convince people to be friendly and to get out of the way of people adding value. Soft security is difficult. It often requires you to grow as a person, sometimes painfully so. This by itself makes it valuable. HardSecurityNonViolenceLimitDamage SoftSecuritySoftSecurity is like water. It bends under attack, only to rush in from all directions to fill the gaps. It's strong over time yet adaptable to any shape. It seeks to influence and encourage, not control and enforce. If nothing within you stays rigid, outward things will disclose themselves. Moving, be like water. Still, be like a mirror. Respond like an echo. -- Bruce Lee I made what I think is a somewhat nuanced and complicated argument about the nature of security. As such it is difficult to summarize. Basically I think that security measures of a purely technological nature, such as guns and crypto, are of real value, but that the great bulk of our security, at least in modern industrialized nations, derives from intangible factors having to do with the social fabric, which are poorly understood by just about everyone. If that is true, then those who wish to use the Internet as a tool for enhancing security, freedom, and other good things might wish to turn their efforts away from purely technical fixes and try to develop some understanding of just what the social fabric is, how it works, and how the Internet could enhance it. However this may conflict with the (absolutely reasonable and understandable) desire for privacy. -- NealStephenson, ComputersFreedomAndPrivacy 2000 (Toronto)NealStephenson ComputersFreedomAndPrivacy See also an [excerpt] by Sir Arthur Conan Doyle that Neal selected to show these ideas aren't new.[excerpt] SoftSecuritySoftSecurity is a collective solution, whereas HardSecurity is often an individual solution. It's important to remember that although the Patterns below are written as prescriptions for you to follow, they are meant as notices for everyone to follow. When SoftSecurity becomes unilaterally enforced, it fails. This is a chicken and egg statement. When SoftSecurity fails--when TheCollective fails to act--only a few heroes try to keep it working. When only one person defends TheCollective, the defense loses its effectiveness and believability. One, the target of the defense will not know the hero speaks for the RoyalWe, and thus attempt to undermine the hero's authority in acting. Two, it may be the case that the CommunityDoesNotAgree, and the hero is acting out VigilanteJustice; acting alone should be good pause to reconsider what you are doing. Finally, while you think you ModelDesiredBehaviour, you are not providing space for others to act themselves, and so the real message you are sending is that they should not act.HardSecuritySoftSecurity TheCollective RoyalWe CommunityDoesNotAgree VigilanteJustice ModelDesiredBehaviour SoftSecuritySoftSecurity follows from the principles of AssumeGoodFaithAssumeGoodFaith. People are almost always trying to be helpful; so, we apply the PrincipleOfFirstTrust, confident that occasional bad will be overwhelmed by the good.PrincipleOfFirstTrust PeerReviewPeerReview.

Newcomers experimentation causes harm, but it is unintentional and forgiveable. Setting aside a place where mistakes are more forgiven permits more experimentation and faster learning, while at the same time containing the extent of the damage to an area nobody cares about. e.g. the SandBox.?SandBox GuidePostsGuidePosts.

Avoid drawing attention to unpleasant stuff. A couple of the banks I've been to have ceiling-to-floor glass walls around all the offices -- even the door is mostly glass. It's more soundproof than cubicles, and people sitting in the waiting room can see why they have to wait -- all the people with authority to give loans / draw up CDs / whatever, are all busy just now. I also think it's less intimidating than walking into an opaque office / cubicle. I'm not sure why. Is it because I've been observing it from the waiting room, so I'm now more familiar with the room -- no longer a complete unknown, someone else's turf ? Is it because I've seen other people doing just what I'm about to do, and other people in the waiting room are witnessing what I'm doing, so that I can be sure I'm about to have a civilized conversation, they're not going to ask me to do something weird like flap my arms like a chicken ? Or some other reason it's not so intimidating ? One bank I've been to had the security vault in the same room as, and directly opposite, the desk with several tellers. They usually left the door standing wide open during normal business hours. There's 2 different soft- security things going on here: (a) While you were waiting for a free teller, you could look at the incredible thickness of the door, and look at the "portholes" on the inside of the door that let you see thick, massive, strong-looking metal gears, and be impressed by how difficult it must be to break in when the door is locked at night. (b) Although it was standing wide open, I never saw anyone actually walk in -- perhaps because they knew that all the tellers faced the security vault -- even when every teller was busy talking to someone, it would be impossible to walk in without the tellers seeing it happen over the shoulder of their customers. Even if someone did walk in, everyone can see that all the security boxes were locked into place. Psychological Controlling relationships to community LimitTemptationLimitTemptation. If you don't have restrictions, nobody will be tempted to break them. People react badly to being forced; they want to rebel against authority and beat the machine. MisdirectTemptation?. Set up attractive targets which if damaged are inconsequential. Same idea as honeypots for crackers.? IntrinsicInterest?. If you provide no interest to anyone who doesn't instrinsically need/want to be there, the fewer punks you will attract. Be boring or even annoying. (cf. ContentOverForm; classical music example below)? ContentOverForm Play Classical Music. Playing this music in train stations and shopping centres has the effect of driving away vandals. MeatballWikiMeatballWiki looks ugly. This is good. Playing the kind of inane classical-lite music they choose for such applications drives away me -- and I have a right to be there! Not good. (indeed the vandals have a right to be there too, they just don't have the right to vandalise). You would be the exception then - most commuters I've seen either don't care either way for the ambience of the experience, being more interested in the utility of the service (ie. getting to point B from point A), or they coccoon themselves into their own little world of sound via a portable/personal device. Vandals however don't care for the utility of the service, their priorities are based on the experience and aesthetics of the place itself. Somewhere in that comment there is an important idea or principle that I feel deserves more attention. Yes, that people who use a place for its function have better intentions and a more valid reason for being there than people who don't care about the function. People who are just 'hanging around' are generally detrimental. (This doesn't stop all vandalism as sadly some vandals are also genuine commuters). People who find a place beneficial will lose that benefit if the place is closed down. It's easier to persuade those people to do certain things and not to do other things if you can convince them "If everyone did that, we'd have to shut down". For example, weight limits on airplane luggage -- There may be plenty of room for one person to bring a ton (2000 lbs, 1000 kg) of stuff on the airplane, but "if everyone did that, the airplane couldn't take off". ScareCrow?. A GuidePost that induces fear or unpleasant feelings in people who you don't feel have a real IntrinsicInterest? in behind there. A psychological PricklyHedge, like a wall of legalese.?GuidePost? PricklyHedge EssentialUse?. If others can find a secondary undesirable use for your service, they may abuse your free service for their ends. Maintain a singular use by reducing non- essential freedoms.? Installing Blue Tinted Lighting. Blue light in toilets, alleys and gas stations makes it difficult for junkies to shoot up as it is hard to find a vein in that light. filtering out of html from wiki pages.

Give the community a SafetyNet to keep it operational in the face of disaster, such the event that its proprietors get by a bus.SafetyNet Anecdotes A little [anecdote] on a NetworkSoftSecurity case:[anecdote]NetworkSoftSecurity I set up a wireless hotspot over a year ago in Highland Coffee, a shop in Louisville, KY, where I'm a regular. We initally used a SOCKS proxy with some content filtering, logging and a login authentication. Accounts were free but you had to sign an agreement that you wouldn't abuse the system, look at porn or do anything illegal. Way too much. Helping people get their laptops configured, resetting passwords, problems with logfiles filling up. Big headaches. Recently we did away with the proxy and have an open system. Initial requests are redirected to a page that introduces the system and informs the user of the general useage policy. Once they click through they are free to go wherever they want. Aside from a few punkass kids, nobody has ever been seen doing anything inappropriate. Trust in SoftSecurity. -- Jeff GerckenSoftSecurity Any others? I feel there may be a PatternLanguage lurking here, if it could be filled out.PatternLanguage How about: Jumping Through Hoops. Put powerful functionality in less convenient places. Example: Don't put the "Edit Text of this page" link at the top of the page. There are functional reasons for not doing this: placing form submit actions (eg: edit text of page) at the top of a page may well result in data loss or corruption if as a result a partially loaded page is submitted. Putting the link at the bottom of the page (or properly: at the end of the HTML) forces the entire page to be loaded before it can be submitted. Another example: Putting the fire extinguisher behind a glass panel, then chaining a small hammer on the wall next to this. Related real world soft security: What would the online analogy for these be? Add Title Here. Some nurses at a hospital kept their milk in a communal fridge, but it was frequently "borrowed". So they stored it in urine-sample flasks instead of milk- bottles. That discouraged the borrowers - it acted as a GuidePost. GuidePost Add Title Here. A children's hospital kept teddy bears and dolls to amuse the children while they recovered. However, when the children eventually returned home, they would often "liberate" their favourite toy. Theft, but how can you punish sick children for it? So the nurses gave the toys bandages, splints, eye-patches etc. Then the children realised that they needed to stay in the hospital because they were not yet "better". Add Title Here. For centuries, people sent messages to each other sealed with a blob of wax. It would be trivial for anyone to break open the wax and read the message, and even add a few lines of text to the letter, but it would be obvious to the recipient that the wax seal had been broken. Add Title Here. I vaguely remember a movie where someone put a single hair on a desk drawer, and put paper behind a door, so that person could tell whether or not someone else had snuck in through that door and rummaged through that drawer. (The envelopes, the wax seal, and the flimsy padlocks, none of them really stop anyone from doing whatever they want, but they make it obvious to everyone when security has failed. The hair-on-the-drawer and the paper-on-the- door seem similar, but they don't tell the honest people to stay out ahead of time (not a GuidePost), and after a security breach they don't tell the honest passerby when security has failed.)GuidePost "Padlocks only keep honest people out". Not sure if this is SoftSecurity or HardSecurity, or something in between... pathetically weak hard security, like two bit padlocks on the petty cash tin (or bikkie tin, more often raided). The point is that it keeps honest people out for very little cost, but would fail (pathetically) with a dishonest person.SoftSecurityHardSecurity It's hard security that can be ignored when necessary by honest people. Perhaps its a sub-variation of GuidePosts and WarningSigns?, where FormFollowsFunction?. (What better way to say "don't open this" than to use a padlock? Beats the language barrier.)GuidePosts? --EricScheidEricScheid Padlocks are also an audit mechanism (albeit a weak one). There is [nominally] a small assurance against theft. As someone who's gone through more than one padlock, I can assure you that it's quite small. More significantly, a padlock may serve as an audit mechanism of sorts. Most attacks against padlocked content results in a broken (or missing) lock. As the first step to recovery is admitting you've got a problem, coming back to a broken or missing lock is an indication of a burglary. The real problem is when you have theft which leaves no signs. Another argument is that a lock, even a small, trivially bypassed one, may help an honest man stay honest. I suppose the flipside is that it might also encourage a dishonest person to be dishonest. -- KarstenSelfKarstenSelf Even the weakest padlock forces the thief to be conciously commiting a crime. You can look in an unlocked box out of curiosity and find yourself taking some without ever making the conscious choice to steal. Also, any unauthorised person caught looking in the box can be punished without them having stolen anything, because they have had to break the lock to get into the box which is in itself a crime. However, the safest place to keep money is in the middle of a table with lots of honest people around. They all know the money is in danger and so will all keep an eye on it to prevent it being stolen. If it's in a box somewhere, they will all think it is safe and won't concern themselves over it. Even flimsier than the padlock is the locks on most of the bathrooms in my city. There's a small hole in the handle on the outside, so anyone with a straightened paper clip can unlock the door and get in. Macintosh computers have the same sort of thing protecting the reset button. Only wimps use tape backup: _real_ men just upload their important stuff on ftp, and let the rest of the world mirror it. -- Linus Torvalds, about his failing hard drive on linux.cs.helsinki.fi Linus wants his files "secure", in the sense that he doesn't want them corrupted or irretrievably lost. Too many people confuse this with "not allowing other people to read the files". (Is this different from "not allowing other people to edit the files" ?) There's an interesting idea at Distributed Proofreaders http://www.pgdp.net/ http://www.pgdp.net/ Second round projects are unavailable until you have proofed more than 50 first round pages. After 50 pages of first round proofing the second round projects will be unlocked for you. This seems like a cool SoftSecurity idea; how could we extend to wiki ? Perhaps something like "Anyone can read any wiki page and create a UserName. People who have created a UserName are allowed to edit the SandBox and their own HomePage. People who have edited at least 2 pages are allowed to add comments to the bottom of any page. People who have commented at least 8 pages and have edited their UserName on at least 2 different days are allowed to edit any page." Um... I'm getting caught up in the details here, making it too complex. How can I generalize this idea ?SoftSecurityUserName SandBoxHomePageUserName The "2 different days" is a kind of SurgeProtector. But the rest doesn't seem to match any of the above SoftSecurity categories; perhaps there's a general pattern we can extract here ? What is a good name for this ?SurgeProtectorSoftSecurity That's HardSecurity. It controls access. See WikiAccessLevels. It is not a good idea as you can game the system; it is completely intolerant to failure. If I sufficiently hated you, I could proofread fifty documents flawlessly, and then turn into the proofreader from hell for the rest. Or even better, deliberatively introduce subtle yet hard to detect errors after that, like mood shifts and racist innuendo. You can probably delete this section when you've read it.HardSecurity WikiAccessLevels Unprocessed readings http://www.hyperorg.com/backissues/joho-oct25- 02.html#leeway http://www.netfuture.org/2002/Oct2202_137.html#1 http://www.mcgeesmusings.net/2003/05/09.html#a3215 http://www.satn.org/archive/2003_05_04_archive.html#2 00266264http://www.satn.org/archive/2003_05_04_archive.html#2 00266264 says: But the problem is - these "security mechanisms" don't create trust. Their very existence creates mistrust. Orlikowski, W.J. (1996) Evolving with Notes: Organizational change around groupware technology. In C.U. Ciborrra (ed.), Groupware and teamwork: Invisible aid or technical hindrance? Wiley: Chichester. Available from http://ccs.mit.edu/papers/CCSWP186.htmlhttp://ccs.mit.edu/papers/CCSWP186.html Should be compared against (Orlikowski, 1992). We don't LimitTemptation, so we will die.LimitTemptation I'm reading the case (*) of a feminist forum that prided itself on inclusiveness that got trolled to nearly the ground by a anti-feminist troll; they did not want to ban the person on philosophical grounds due to their ideal of RadicalInclusiveness. This left them open to two months of vitriole until the forum hosts banned him. Similarly, MrBungle was finally banned when a wizard stepped in and unilaterally banned him, this after a long argument over free speech. Similarly, our adamant principle of SoftSecurity here leaves us open to trolling with the implicit goal of getting us to ban someone's IP. The more famous our philosophy becomes, the more we open ourselves to "career" trolls who will spend a ridiculous amount of time here getting us to ban their IP to prove we are wrong. I think that since the cyberstalking laws have changed, and since invariably these guys are in America, Canada, Australia, or the UK, we should investigate what criminal charges we can lay as that seems to be the only truly effective means at exiling someone. It would be worthwhile to know, if only to make the threat of a LegalThreat enough of a deterrent. Meanwhile, it seems we are hitting the limits of our current architectural defenses, so we should dream up more. RadicalInclusiveness MrBungle SoftSecurity LegalThreat Additionally, we could ban a few IPs now and then just for the hell of it. A perfect record is always going to be trolled. Best to be WabiSabi?, perhaps. -- SunirShah?SunirShah The problem with so sophisticated methods is the sheer amount of information about the rules, and many beginners involuntarily can easily broke some of them. This is in sharp contrast with HardSecurity where the newcomer immidiately gets feedback on his actions. I believe much more effort should be excerted in the direction of developing user friendly teaching techniques for the SoftSecurity rules then developing new ones. An immidiate example can be giving somwhere at the top of the wiki pages explicite links to rules that are meant to govern this given page (something like 'This is a ThreadMode page'). -- ZbigniewLukasiakHardSecuritySoftSecurity ThreadModeZbigniewLukasiak (*) Herring, S., Job-Sluder, K., Scheckler, R., and Barab, S.
