Now that we have enough details about how the >NSA eavesdrops on the Internet, including today\’s disclosures of the NSA\’s deliberate weakening of cryptographic systems, we can finally start to figure out how to protect ourselves.
For the past two weeks, I have been working with the Guardian on NSA stories, and have read hundreds of top-secret NSA documents provided by whistleblower Edward Snowden. I wasn\’t part of today\’s story — it was in process well before I showed up — but everything I read confirms what the Guardian is reporting.
At this point, I feel I can provide some advice for keeping secure against such an adversary.

via Schneier on Security: How to Remain Secure Against the NSA.

I’m split preparing for presenting at Madison, Wisconsin’s Nerd Nite on October 30, 2013. Schneier covers several important notes as to how to handle security in general against a state-level actor, but the lessons are useful to implement in general.

Lesson three in particular is valuable. If you assume someone CAN be listening to your activity, it is easier to avoid doing something stupid. Where you should be worried about being discovered, act on those fears. Air gaps or one-way network connections can protect confidential information better than any firewall.
