Have you considered the possibility that a thief opens a laptop, resets the BIOS (by removing the CMOS battery)? Or that the SSD can be removed and wiped/ replaced by a different disk? If you disregard those situations, then you can try to find an option in your BIOS Setup to disable booting from USB and configure a BIOS Setup password. Also note that the ...

If you have very low budget and some Linux skills, then instead of buying commercial surveillance system, I suggest you to build one yourself. You will need: a few Microsoft LifeCam HD-3000 cameras (35$ each, use this specific model, as it has the best handling for different light levels, which is important for motion detection) cheap computer (you can ...

If I look at a presentation about the topic it does not look like replacing defense in depth, but replacing a heterogeneous environment containing lots of different mostly independent and sometimes incompatible security solutions with a more structured environment where all parts work together to better detect and deal with the risks. It still contains ...

Having a good password to protect the system is a core safety feture. I agree that you should lock it under password and add. However the critick is ill fit. I agree whit the statement that its much easyer to phisicly damage the system on the location that bother to use the computer. Still the computer is vunreable from outside the LAN.

Protection of the machines are in most cases not against physical destruction, but against data stealing. If others have physical access to the machine, real protection is impossible. BIOS passwords can be easily overriden by plugging out the power, dismantling the machine at taking out the bios battery for around a half minute. This resets the bios, ...

It sounds like the worst that could happen directly to you is your trains get damaged. If you don't mind, then you're right and security isn't necessary since you won't be bothered. If you want to save some time/energy and prevent that from occurring greatly, just add a password to the computer. It should only take a few seconds and I personally don't see ...

Security is necessary in order to counteract "risks" to a system. You need to determine what those risks are and if "loss" in that area is acceptable. Presumably, this train set up is not public, but in a locked building where people need a key to enter, or if allowed in, are monitored by other people watching. Yes, it is possible for someone to come in ...

In general, any computer that has the capability to go online needs to be secured. This includes not only "laptops" and other things people consider to be computers, but thermostats, sprinkler controls, and any other programmable device. The problem may or may not be what the attacker can do to you, but also what the attacker can use your computer to do to ...

If you're truly paranoid, you need to remove (rather than clean) all non-volatile memory, as it can mask data from the OS. This includes any solid-state memory(SD/flash), system "rom" in EEPROMS, NVRAM/PRAM and any device that might have non-volatile slack space memory.

Unless you work for a 3 letter agency or something similar your risk profile is very low. However if you are removing the RAM, resetting the BIOS, and removing any storage should prevent just about any data access.

If you have removed the hard drive and checked that no removable media was left in it, then none of your data can be found on it. (They will be able to see your BIOS settings, but that isn't considered sensitive data for a dead laptop.) By the way, if you have an SD slot, make sure you check that too.

If you're concerned about BadUSB and similar attacks, you'll just need to resort to checking all of your ports every time you come back after leaving your computer unattended. Do note, however, that even this doesn't protect you from BadUSB. BadUSB means I can take a normal piece of USB equipment, flash custom firmware on it, and wreak havoc with it. This ...
