While security is a very broad concept that has [[wikipedia:Security|many definitions]], in the concept of software, it mainly refers to ensuring someone cannot interact with your devices in a way that you do not want. For example, running software on your computer without permission. Security is most useful when thought of through the lens of [[Glossary#Threat modelling|threat modelling.]]

=== Threat ~~Modelling~~ ===

=== Threat Model ===

Threat ~~modelling~~ is ~~the process~~ of ~~planning out~~ how someone might interact with your device in a way that you do not want, and ~~making~~ a plan to prevent it. For example, if you do not want someone to be able to take your laptop apart and read your files off of your [[Glossary#Drive|drive]], you could encrypt it. It's important to understand what exactly you are concerned about, instead of just trying to "be secure."

=== Drive ===

A drive, or sometimes disk, is a device that contains data, for long periods of time. This is different from RAM, which only stores memory temporarily. The main tradeoff being that reading and writing to a drive is much slower than RAM. Drives can come in many forms, such as [[Glossary#SSD|SSD]], [[Glossary#HDD|HDD]], [[Glossary#(e)MMC|eMMC]], etc. The term drive can be a bit confusing though, as drives used to refer to devices with removable media, like [[Glossary#CD|CD]], [[Glossary#Floppy Disk|Floppy]], and even old Hard Disks. In present day though, drives rarely have removable media. The media itself cannot be read or interacted ~~without~~ without the hardware to ''drive'' it, which is why it ~~was~~ called a drive.

=== SSD ===

Solid State Drives are drives which have no moving parts. ~~These drives instead~~ of having disks, have flash chips on a board that contain the data. There are a few different types of flash ~~chip~~, but most commonly [[Glossary#NAND|NAND]] is used. SSDs are usually removable from the device, and can be upgraded as needed, though some devices do have their SSD [[Glossary#Soldering|soldered]] to the motherboard. SSDs are usually either SATA or NVME, with NVME offering faster speeds, but usually at a higher price.
