secure your system

by Deactivated5775 • 6 Dec 2008, 14:16 • Journals
Since crossfire is definitely the best place to find creative minds I'm in need of some.

I have this project I have to work on for university.

It deals with ways in which you can "secure your PC-system against possible threats (and here comes the funny part) when it's not connected to any network (= no internet, LAN, whatever).

Things I've thought off:
- Backups (external HD, dvd's)
- RAID
- Encrypted documents
- A safe for your case / screen etc
- ...

your PC system can overheat and damage any component

in any case, overheats isn't a word :p

and a beter answer would hv been "proper cooling"

How about... not connect it to a network. The only non-networked threats I could think of would be blurted out by setting up a fence, keep it clean, cover it in fluffy stuff.

HD's never crash, PC's never break, systems never overheat

cough

I actually never had a HD crash that was not internet-related.

that's a bit too obvious if you ask me, can't really think of major companies without any passwords on their systems but OK, i could mention it in my report :p

You could also mention USB sticks, extern HD's, etc. that are virus infected. If you connect them to your non-network desktop, for examble to transfer data, they are a possible threat too.

Educate the users (or are we talking about _your_ computer now?).

Oh, and UPS/anti-lightning-stuff.
Dust, humidity, use SSD disks(no moving parts = less error-prone), RAID, backup to external stuff (tapes etc), don't install things you don't know what is or don't need, etc..

A sufficiently stupid user can break any system

could you plz explain the SSD disk thingie?
Parent

plekter 6 Dec 2008, 15:08
SSD disks are disks which uses some kind of flash memory instead of the conventional platters. Conventional disks have a habit of crashing every now and then, quite often due to sectors gone bad. They break when they fall, so if someone for some reason should drop your computer (or an earthquake?), a conventional disk may risk breaking. The SSD disks have no moving parts and thus bumps or shaking do not break them.

Platters and other compenents of HD's are indeed pretty sensitive but the capacity of the conventional hard disks are huge compared to flash memory, afaik, flash memory goes up to 16 GB or smth or am I wrong?

The technology is quite similar to that of flash memory, but remember that a 3.5" disk is much bigger than your USB-key flash memory. Biggest SSD I've seen is 250 gig. Shit expensive, but still.

Hmmm k :)

thx for the info, are you also studying computer sciences :)?
Parent

Yup, first year. But you seem to be studying a different side to it than me, informatics am i right?

hehe :)

Some things I've been seeing: java, isa-level, assembler, stacks, binairy calculus, datamodelling and so on :)

How about progs like "truecrypt"?

U can have a master pw for the whole PC and pw's for each partition to make them visible
