Prevent cold boot attack on running laptop by overwriting ram
Id like to use my laptop as a recording device when i leave home, but there would still be the possibiltity for a cold boot attack or with ddr3ram even warm boot attack is possible as i have read. Could one overwrite RAM before leaving the laptop locked and make cold boot inposssible that way?
I found this http://manpages.ubuntu.com/manpages/utopic/en/man1/sdmem.1.html
will sdmem really overwrite the RAM of a running system? If so could you write me a script that does this everytime i lock my pc?
