and assets.
Remember the distinction being between threats and risks, right? Threats is usually the active or the technology that's actually implementing the type of attack where the risk is the potential that the threat will do damage.
Okay, So what are some mobile device challenges? Okay, we've got physical size access the mobile networks, like three G and five g in wifi et cetera, and we've got OS vulnerabilities. Remember these devices? Air, just like regular os is now a day. So they have the same vulnerabilities that you're
desktop systems have access to.
Okay, what are the three major components of Iowa Security? All right, we've got system data and applications security.
And could you add 1/4? Well, yeah. We could add network security.
Even though I O. S doesn't implemented new technology. They implement the same technologies you would think of that most providers offer nowadays. S S L T L s. Those types of things.

So we've got a couple of different types of jailbreaks, right? We've got tethered, semi tethered, untethered, semi untethered, and kpp less so. Tether jailbreaks, usually
require computer, and they take advantage of the device hardware. So they're finding vulnerabilities and the device hardware
untether jailbreaks that usually take advantage of Iowa's colonel flaws and typically don't require computer just user interaction. While they all require user interaction in some way, kpp less this is bypassing the Colonel Patch protection process. So those are the different types of jail breaks we can perform.
