There's a scene in the first Star Wars movie where an unauthorized R2D2 plugs itself in to the Death Star computer and knows everything whats going on - no passwords or security necessary.
To quote from this article on PandaSecurity.com:
While Luke Skywalker and his friends are still hiding in the Death Star control center, we see another major cyber-security mistake. Once R2-D2 manages to access the Galactic Empire’s computer network, he gets the space station’s blueprints without difficulty.
Given that this information is so critical for the security of all the inhabitants of this gigantic artificial planet, you would expect that, at least, access to those files would be password-protected.
The article gives a few more examples of how weak cybersecurity is in the Star Wars Universe.
However, it's possible that there is some cybersecurity, but the movies cut it out.
Is there any cybersecurity measures explicitly mentioned in the Star Wars universe in regards to computers?
And if not, is it ever explained why?
(I'm not looking for reasons why the Death Star security system was so weak. At the end of the movie, we see the General ignore the engineers' warning of a flaw. So it's possible the General is merely an idiot. I want to know in regards to all Star Wars computers in general.)
