One common puzzle for the security-minded is how to work with confidential data on the road. Sometimes you can't bring your laptop, or don't want to. But working on somebody else's machine exposes you to malware and leaves behind all kinds of electronic trails.

Suppose a bad guy guesses the password for your throwaway Yahoo address. Now he goes to major banking and commerce sites and looks for an account registered to that email address. When he finds one, he clicks the 'forgot my password' button and a new one is sent -- to your compromised email account. Now he's in a position to do you serious harm.

As militias go, the Ohio Defense Force is on the moderate side.

Scott Ritter is a very well-known archetype of a certain U.S. military officer. Very hard talking, very ambitious, zealous, and completely consumed with carrying out his mission. He's a guy who, throughout his career, I would say, did not break rules, but he worked around road blocks.

The first reports of AIDS closely followed the inauguration of President Ronald Reagan, whose 'family values' agenda and alliance with Christian conservatives associated AIDS with deviance and sin.

Experts said public companies worry about the loss of customer confidence and the legal liability to shareholders or security vendors when they report flaws.

Clinton saw himself much more as the steward of alliances and of consensus that moved in the right direction. He didn't see himself as someone who could change the overall thrust, I think, of global policy.

Among all the upheavals of war with al Qaeda, the surest indicator of the historic stakes is the ongoing rotation of top U.S. government managers -- scores at a time -- into a bunker deep underground and far from Washington.

The government of Sudan, employing a back channel direct from its president to the Central Intelligence Agency, offered in the early spring of 1996 to arrest Osama bin Laden and place him in Saudi custody, according to officials and former officials in all three countries.

During the morning rush hour on March 20, 1995, the Japanese cult Aum Shinrikyo placed packages on five subway trains converging on Tokyo's central station. When punctured, the packages spread vaporized Sarin through the subway cars and then into the stations as the trains pulled in.

The United States, a signatory to the Chemical Weapons Convention, destroyed the last of its stocks of VX and other chemical agents on the Johnston Atoll, 825 miles southwest of Hawaii, in November 2000.

First developed as a weapon by the U.S. Army, VX is an oily, odorless and tasteless liquid that kills on contact with the skin or when inhaled in aerosol form. Like other nerve agents, it is treatable in the first minutes after exposure but otherwise leads swiftly to fatal convulsions and respiratory failure.

In the urgent aftermath of Sept. 11, 2001, with more attacks thought to be imminent, analysts wanted to use 'contact chaining' techniques to build what the NSA describes as network graphs of people who represented potential threats.

On March 12, 2004, acting attorney general James B. Comey and the Justice Department's top leadership reached the brink of resignation over electronic surveillance orders that they believed to be illegal.

Ghostery lets you spy on the spies in your computer. For each web page you visit, this extension uncloaks some -- but not all -- of the invisible tracking software that is working behind the scenes.

I do read licenses, and they aggravate me, but a computer isn't much good without software. When I need a product, I hold my nose and click 'agree.'

Given the volume of PC sales and the way McAfee runs its operation, I imagine there must be thousands of phantom subscribers -- folks who signed up once upon a time and left the software behind two or three computers ago.

Dell fills its computers with crapware, collecting fees from McAfee and other vendors to pre-install 'trial' versions.

The Obama administration, like those before it, promotes a disturbingly narrow interpretation of the Fourth Amendment, misapplying the facts of old analog cases to a radically different digital world.

In effect, you cannot stop Iraq from growing nasty bugs in the basement. You can stop them from putting operational warheads on working missiles and launching them at their neighbors.
