Title: Encrypting your Laptop Data after Closing the lid Post by: ianferns on May 15, 2015, 09:38:59 AM I have heard people and all these marketplaces guys and other hackers, who can just close their laptop lid, and have everything secure and encrypted even if someone had access to their laptops.
Can anyone suggest on how I can do the same ? Title: Re: Encrypting your Laptop Data after Closing the lid Post by: MysteryMiner on May 15, 2015, 10:25:27 AM Full disk encryption. Fow Windows XP Vista and 7 I recommend DiskCryptor. After system is fully encrypted set the power management to Hibernate the laptop when lid is closed. When it finishes hibernating, everything is encrypted, including the hiberfile.sys and there is no decryption key in memory. To Resume power laptop on, enter the password for bootloader and be fully up and running as soon as it finishes reading the encrypted hiberfile.sys
Don't use Standby when lid is closed (the default option for many systems). It is possible to bypass the Windows login screen and the encryption keys still reside in memory when laptop is fully-on or in Standby.

I happen to use a Mac btw. Any suggestions in particular to that ?

Any suggestions in particular to that ? I think the only full-disk encryption for MacOS are from Norton. It is closed source and unsuitable to secure private data. Don't use Apple.Title: Re: Encrypting your Laptop Data after Closing the lid Post by: Buffer Overflow on May 15, 2015, 08:44:51 PM https://en.m.wikipedia.org/wiki/Comparison_of_disk_encryption_software

They remove the hard disk, and plug that hard disk to their own computer. So whatever encryption method you use shall manage that.
