[Walker] has a very interesting new project: a completely different take on a self-destructing USB drive. Instead of relying on encryption or other “visible” security features, this device looks and …read more Continue reading USB Drive Keeps Your Secrets… As Long As Your Fingers Are Wet?
I am reading about access control list. In general, ACLs use “owners” (users) rather than individual processes. Could you explain the meaning of this line?
When will operating systems use access control lists and capability lists?
This may be comparing chalk with cheese, but I’m wondering how these tools compare: pros and cons, similarities and differences, and situations where you would use one vs the other.
