security - Is it safe to buy a dedicated linux server? -

i'm planning buy dedicated linux server.

i'll receive root password , i'll change .and i'll have ssh access. safe me keep personal data on server ?

i mean , if change root password way datacenter server located ,to access server files while running , if change root password?

i know root password can reset if restart server , boot install cd or flash .

but if not reset root pass , can access files using usb cable or physical port not know?

thank all

in general, there no security solution can deal physical access in hostile environment.

they pull want off there. if disable remote access, can pull physical disks , read them.

if encrypt it, there variety of attacks (such man in middle, since control network) expose key relatively little effort.

the only realistic way prevent access encrypt files on end , never ever ever send either raw files or key. however, applies if want server store files.

if wanted to, example, host website database on machine, there no practical security techniques @ time prevent them reading decryption keys , data memory or disk.

however, not putting bit of effort security/encryption bad. using encrypted partition or file container effective @ slowing down rogue actor (ie 1 without support of company) sufficiently unless targeted specifically, they'd move on easier target.

to close: major corporate hosts relatively safe. there precautions on end prevent staff pulling files , data customer machines. can still happen, unlikely.
