Protocols and devices keep data safe because;

• they have passwords so no one can break into them
• they have viruses that no one else can get 
• they have a security key that keeps people away so when they try to break in the security key knows when somethings happening.
• protocols have something called encripted, this is a device that blocks people from your internet and has all different codes behind it to keep it safe.
