數(shù)據(jù)安全 數(shù)據(jù)銷毀

You have a pile of DVDs with sensitive information on them and you need to safely and effectively dispose of them so no data recovery is possible. What’s the most safe and efficient way to get the job done?

您有一堆DVD，上面有敏感信息，因此您需要安全有效地處置它們，因此無(wú)法恢復(fù)數(shù)據(jù)。 完成工作的最安全，最有效的方法是什么？

今天的“問(wèn)答”環(huán)節(jié)由SuperUser提供，它是Stack Exchange的一個(gè)分支，該社區(qū)是由社區(qū)驅(qū)動(dòng)的Q＆A網(wǎng)站分組。

問(wèn)題 (The Question)

SuperUser reader HaLaBi wants to know how he can safely destroy CDs and DVDs with personal data on them:

超級(jí)用戶閱讀器HaLaBi想知道他如何安全銷毀帶有個(gè)人數(shù)據(jù)的CD和DVD：

I have old CDs/DVDs which have some backups, these backups have some work and personal files. I always had problems when I needed to physically destroy them to make sure no one will reuse them.

我有一些備份的舊CD / DVD，這些備份有一些工作和個(gè)人文件。 當(dāng)我需要物理銷毀它們以確保沒(méi)有人會(huì)重用它們時(shí)，我總是遇到問(wèn)題。

Breaking them is dangerous, pieces could fly fast and may cause harm. Scratching them badly is what I always do but it takes long time and I managed to read some of the data in the scratched CDs/DVDs.

打破它們是危險(xiǎn)的，碎片可能會(huì)飛得很快并可能造成傷害。 我經(jīng)常會(huì)嚴(yán)重刮擦它們，但這需要很長(zhǎng)時(shí)間，而且我設(shè)法讀取了刮擦CD / DVD中的某些數(shù)據(jù)。

What’s the way to physically destroy a CD/DVD safely?

安全地物理銷毀CD / DVD的方式是什么？

How should he approach the problem?

他應(yīng)該如何解決這個(gè)問(wèn)題？

答案 (The Answer)

SuperUser contributor Journeyman Geek offers a practical solution coupled with a slightly mad-scientist solution:

超級(jí)用戶貢獻(xiàn)者Journeyman Geek提供了一個(gè)實(shí)用的解決方案以及一個(gè)有點(diǎn)瘋狂的科學(xué)家解決方案：

The proper way is to get yourself a shredder that also handles cds – look online for cd shredders. This is the?right?option if you end up doing this routinely.

正確的方法是讓自己也可以處理CD的碎紙機(jī)-在線查找CD碎紙機(jī)。 如果您最終要這樣做，那么這是正確的選擇。

I don’t do this very often – For small scale destruction I favour a pair of tin snips – they have enough force to cut through a cd, yet are blunt enough to cause small cracks along the sheer line. Kitchen shears with one serrated side work well too. You want to damage the data layer along with shearing along the plastic, and these work magnificently. Do it in a bag, cause this generates sparkly bits.

我不經(jīng)常這樣做-對(duì)于小規(guī)模銷毀，我傾向于使用一對(duì)錫剪-它們有足夠的力來(lái)切破CD，但過(guò)鈍卻會(huì)導(dǎo)致沿純線的小裂紋。 帶有鋸齒狀側(cè)面的廚房剪也能很好地工作。 您想要破壞數(shù)據(jù)層以及沿著塑料的剪切，這些工作效果非常好。 放在袋子里做，會(huì)引起火花。

There’s also the fun, and probably dangerous way – find yourself an old microwave, and microwave them. I would suggest doing this in a well ventilated area of course, and not using your mother’s?good?microwave. There’s a lot of videos of this on YouTube – such as?this?(who’s done this in a kitchen… and using his mom’s microwave). This results in a very much destroyed cd in every respect. If I was an evil hacker mastermind, this is what I’d do. The other options are better for the rest of us.

還有一種有趣且可能很危險(xiǎn)的方法-為自己找到一個(gè)舊的微波爐，然后將其微波。 我會(huì)在過(guò)程中的通風(fēng)良好的地方建議這樣做，而不是用你母親的良好的微波。 有很多的YouTube上的這個(gè)視頻-比如這個(gè)(誰(shuí)在做這在廚房...，用他媽媽的微波)。 這導(dǎo)致在各個(gè)方面都嚴(yán)重破壞了CD。 如果我是一個(gè)邪惡的黑客策劃者，這就是我要做的。 其他選擇對(duì)我們其他人更好。

Another contributor, Keltari, notes that the only safe (and DoD approved) way to dispose of data is total destruction:

另一個(gè)貢獻(xiàn)者Keltari指出，處置數(shù)據(jù)的唯一安全方法(且獲得DoD批準(zhǔn))是完全銷毀：

The answer by Journeyman Geek is good enough for?almost?everything. But oddly, that common phrase “Good enough for government work” does not apply – depending on which part of the government.

Journeyman Geek的答案幾乎可以解決所有問(wèn)題。 但奇怪的是，“足以勝任政府工作”這一常用短語(yǔ)并不適用-取決于政府的哪個(gè)部門。

It is technically possible to recover data from shredded/broken/etc CDs and DVDs. If you have a microscope handy, put the disc in it and you can see the pits. The disc can be reassembled and the data can be reconstructed — minus the data that was physically destroyed.

從技術(shù)上講，可以從碎/破碎/等CD和DVD中恢復(fù)數(shù)據(jù)。 如果您有便攜式顯微鏡，則將光盤放入其中，即可看到凹坑。 可以重新組裝光盤，并可以重建數(shù)據(jù)-減去物理?yè)p壞的數(shù)據(jù)。

So why not just pulverize the disc into dust? Or burn it to a crisp? While technically, that would completely eliminate the data, it leaves no record of the disc having existed. And in some places, like DoD and other secure facilities, the data needs to be destroyed, but the disc needs to exist. If there is a security audit, the disc can be pulled to show it has been destroyed.

那么，為什么不將光盤粉碎成灰塵呢？ 還是將其燒成酥脆？ 從技術(shù)上講，這將完全消除數(shù)據(jù)，但不會(huì)留下光盤的記錄。 在某些地方，例如DoD和其他安全設(shè)施，數(shù)據(jù)需要銷毀，但光盤必須存在。 如果進(jìn)行了安全審核，則可以拉出光盤以表明它已被破壞。

So how can a disc exist, yet be destroyed? Well, the most common method is grinding the disc down to destroy the data, yet keep the label surface of the disc intact. Basically, it’s no different than using sandpaper on the writable side, till the data is gone.

那么，光盤如何存在卻又被銷毀？ 好吧，最常見的方法是將光盤磨碎以破壞數(shù)據(jù)，同時(shí)保持光盤標(biāo)簽表面完好無(wú)損。 基本上，這與在可寫面上使用砂紙沒(méi)有什么不同，直到數(shù)據(jù)消失為止。
