Even Gutmann himself doesn't think folks need 35-pass on any even remotely-recent hardware. You'll probably then be pointed at specific full-disk encryption and at physical device destruction, if what I've seen recommended in the past for secure sites is any guide, but do check with your site security contact or site security officer directly. (If you think you need more security than that, you're probably working with far more sensitive data than most users, and should seek specific technical and legal guidance, and not a reply some somebody in a user forum. Multi-pass overwrites like srm and diskutil secureErase are arguably a waste of time on recent disks, and overwriting once or maybe twice should do fine. Srm (which is part of OS X, BTW - launch Terminal.app and see man srm - be very careful where you aim that tool), won't particularly help with SSDs as you have to use the secure erase function with the SSD or somehow force the device to reuse and overwrite all of the storage irrespective of the wear leveling used in SSDs, nor is srm or similar sorts of block overwriting particularly effective against any data that's been stored in revectored blocks on hard disks in blocks with errors. That is free, supported by Apple, and it prevents all of the sorts of sensitive data leakage that you've listed here, and more. Cheers and thanks!Įnable Apple's FileVault 2.

BLEACHBIT FOR IPAD FREE
Would be great if it's open-source, may be not free though. Primary focus is on privacy guarding here, not on system speed improvement.

The goal is to have an easy-to-use yet effective, scaling and adjustable tool to cleanup sensitive data spills - temporary files, web history, cookies, messaging history, logs etc.
BLEACHBIT FOR IPAD PC
Just migrating from PC world and looking for good analog for BleachBit ( ) application. And they are somewhat different from traditional HDDs, including ways of sanitisation. a lot of data a regular user like me hardly imagines.Ī separate question is whether those wiping methods (zeroing, random, DoD, Gutmann atc.) are (1) required and (2) effective when talking about sanitisation of SSD? I don't think it would be too far from the truth if I say that 90 to 100 percent of modern Apple notebooks are equipped with SSDs. But the problem is - I don't know what to wipe, with the exception for files I manually created myself (documents, spreadsheets etc.) Which is not enough of cause - any OS does a lot behind the scene. I also can wipe files or folders with BCWipe or alike. I can move individual files into trash and securely empty it.

All in one, it makes quite effective and user-friendly set. You also can write those rules and add them yourself.
BLEACHBIT FOR IPAD DOWNLOAD
These rules are expandable- some come preset, some you can download and add (for example, what to clean if MS Office is installed, or Firefox or iTunes etc). It has srm-like thing built in and a bunch of OS and application-specific rules attached telling BleachBit what to look for and wipe. BleachBit AFAIK is actually a kind of what you suggest. Thanks for your reply! Knowing the things which should be wiped is the issue.
