There is no easy way to secure yourself

The Privacy Project

The New York Times has an excellent series of reports on topics related to digital privacy. I don't think technical people will be surprised by the technical issues described but some of the motivations of hackers might not be something we think about. And both the layman's description of the technical aspects and of the hacker motivations are elements that can be shared with friends, family and co-workers.

The message for us is that surveillance is far more common than most people would suspect and that being truly safe is extraordinarily difficult. The article puts to rest the idea that “I’m not important enough to be targeted.” Anyone who might be a conduit to a “high value target” must also be considered a possible target. Modern hacking tends to be a multi-step process by which the attacker uses lower level people to collect the information that will then be used to compromise the primary target. This is one of the reasons organizations need to consider security on an institutional basis and not based on the perceived vulnerability of specific individuals. A chain is only as strong as its weakest link.  One last thing: don’t assume that the value of your site is the value it represents to hackers. Hackers may want to use your server to run a variety of criminal activities.

Don't Eat the Cookies



Google has a useful set of tools for blocking cookies -- the type your web browser generates and not the nice ones you eat. First of all, let's set straight what a cookie is. It's a small text file created by your browser at the behest of the site you have visited -- or of a third-party's site somehow related to a site you've visited.

Cookies are not programs, viruses, or Trojan horses. The intention of a cookie is to save user or activity information so that the site may "recognize" you and hopefully make your experience on their site better. The downside is that cookies can create privacy issues. This is especially true with the cookies set by advertisers. In general, you want to allow cookies from the sites you visit but probably not from third-party sites, such as DoubleClick. The link at the top of the page tells you how you may stop third-party cookies plus the ones that DoubleClick set. I had not realized that DoubleClick had gotten around the third-party cookie blocking systems, but it has. The add-ons and instructions on this Google page -- the owners of DoubleClick -- gives you all the information you need to know.
