You think that's allot?

Across the pond Delaware tag # 6 is expected to sell for around 1 million dollars...

A few years ago the prize to a contest/lottery was a 1950 something car with a matching Delaware 2 digit tag. The tag at that time was worth more than the car.

No, it doesn't make any sense to most people here either......

Clearing swap and hibernation files properly

Bill

Why swap? Again...

This guy got his security background from where? A dust bin maybe?

If you are worried about security...

Why are you using a swap file at all? Get off a few bob, buy more RAM, and shut off swap file completely. Most machines running WinXP and a GB of RAM can do away with it. Even some 512MB machines have enough if they aren't bloated with crapware. Swap file is the RAM of last resort. You are paying to use it in performance and security.

If you are going to recommend encryption products...

Try products that have been peer reviewed like OpenPGP and most open source stuff so that you aren't just handing back doored drives to the Government etc. No proprietary product like BCwipe, Symantec, or others can be trusted to be free of hidden trap doors to keep the piece with various agencies. It wouldn't surprise many people if the companies were even being payed to have extra keys. The software is closed so how would you know?

Unless Seagate and others are going to hand over their firmware for review, I wouldn't trust any of the disk drives entering the market with built in encryption either. These drives are already designed to have multiple keys for IT admins etc. Seagate says they can't recover data but why should we believe them?

Hibernation...

Is a security problem for more than a few reasons and while popular with laptop users, is anything but stable on the desktop. More than a few machines and/or accessories do not play nice with this. It should be disabled unless you have a specific need for it. BTW... Many laptops are slow because they are laptops but also because they are notoriously RAM starved products.

Beyond that... Some encryption products only work properly when the machine is shut down. Standby and Hibernate can leave them wide open.

File and Free Space Erasers...

Understand that Windows locks many files, and some whole directory trees, and whatever services/applications are running lock even more files/directories. Most of these things cannot wipe all the slack space on a drive. It's not going to be any better in other OS's either and could be worse.

As these locked files may still move when a volume is defragged, there may be data trapped in the slacks of these files. You'd think that if one function, erasing, can't access the files nothing else can but you'd be wrong. Defragmenters and backup/restore operations regularly have access to "locked" files that Eraser doesn't.

Slacks can be very large and contain considerable amounts of data, especially as drives keep getting bigger. It all depends just which OS is involved and what the cluster size is on the volume how dangerous such a problem might be. If you rely on such a product, you need to know what it's not touching, which is major amounts of space on Windows XP/Vista machines.
