secure delete with srm, sfill, sswap, smem and centry

[labbe5]

secure-delete can be installed from standard Ubuntu and Debian repositories.

This would install three commands on your system. These are:

srm – This command is used to delete files and directories from your hard drive.
sfill – Wipes all data from free space on your disk. Running this makes sure there are no more recoverable files on the disk/partition.
sswap – Wipes all data from the swap partition.

Another useful tool to have is smem.

smem can be installed from Ubuntu and Debian repositories.

This tool securely wipes the computer memory (RAM), which could contain the state of running programs as well as sensitive program data, even after the computer has been powered off.

Pushing the security/privacy envelope, there is Centry :

Centry is a panic button intended to protect users against Cold Boot Attacks, Direct Memory Access Attacks and other live system threats.

The panic function can be activated through the GUI or through a network request (through browser, smartphone, etc). Upon recieving the panic instruction, Centry will attempt to remove sensitive keys from memory, securily overwrite the RAM and then force a shutdown.

How to run Centry :
git clone https://github.com/0xPoly/Centry.git
sudo python centry.py "password"
