Reliability:
-no errors
-does what its supposed to do
-no "bugs", bug-free. bugs=errors
-performs the way we expect it to
Integrity:
-when a virus is introduced into a software, the software does what the virus wants it to do, not what its supposed to do.
-denial of service: a device has a limitation that caters to a certain amount of people. if the request for the service suddenly increases, the sevice will break. DoS is a program that accesses web servers many times per second and makes the server shut down,
Security:
-authentications--usernames and passwords
-boxes with letters to prevent DoS attacks
-installing anti-viruses and firewalls (DeMilitarizationZone), encryption
-data in flight-is traveling, out of firewalls/protection etc., data at rest-within firewall, data center, protection
-HTTPS means it is secure
