Beth threw down the gauntlet, and I had to pick it up. I’m sort of surprised I hadn’t written about this before. I think a lot about both of these, not so much for myself, but for organizations that I work with whose work is fairly sensitive.
First off, some definitions – I think that these two terms do get mixed up quite often, and understanding what’s really being meant by them in a technical context is important.
Security, in this context, is the concept that your personal computing resources and data are safe from both prying eyes, as well as hijack by crackers and spammers who will use those resources and data for their nefarious ends. In the case of your computing resources and personal data inside that box you call your laptop, or protecting the whole of your home or office network, security is a matter of using specific tools that prevent unprivileged outsiders from getting in. Wifi passwords, firewalls, password protected fileshares, virus protection software, etc. are the tools of the trade here. Security of your private data that is “in the cloud” is largely at the mercy of the software developers who hold your data. Luckily, most of them take security quite seriously. (That said, your data “in the cloud” can be compromised by lack of security on your network or laptop – someone installs a key logger, for instance, and grabs all of your passwords.)
Privacy, in this context, is that you can control, in a granular sense, what information about you is exposed to whom. Privacy is, as Beth says, primarily a matter of human behavior, but there are very interesting intersections with technology and security. In some instances, services have default privacy settings that are a lot less private than someone might like – and it takes some know-how to figure out how to correct those settings. Privacy is, also, a set of decisions that get made – sometimes in haste, or without much consideration. Your drunken decision to post that picture of you (or a co-worker) dancing in your underwear on a table at a party, the cat is out of the bag, and may never be able to be put back.
Security and privacy in the context of online communities, as Beth points out, are different beasts. The software that drives online communities (such as Drupal, phpBB, and others) have options to allow for varied levels of security. You might need to have a password to see anything. Or you might just need a password to make comments. You might not be able to just register for an account – you might need to go through an admin. These days, most software driving communities have roles you can assign people to, with specific privileges granted per role.
But privacy is made up of policy (the policy of the organization running the community) as well as the behavior of the members – their collective agreement that “what happens in Vegas, stays in Vegas.”
