Today, talking with a person knowledgeable in ICT education in Indonesia, he recommended not to spend time on an offline solution because it is impossible to ensure security. He expects that, for fun, kids will hack it and load inappropriate content, which can cause a big stir in Indonesia. Online is better because a website is monitored and thus intrusions are detected, blocked and sites restored. Therefore it is better to focus on getting schools online than trying to provide offline solutions. One caveat is that his company delivers online solutions.
How secure is the RACHEL Plus?
Have there been any problems with people hacking into the WiFi servers?
What precautions do people take?
If a server is hacked, how to restore it? (Do people keep a full backups?) Although, with no patch, if someone broke in once, they can simply break in again.
What do you think?
