Terms in this set (106)
What are the five elements of security? Confidentiality, Integrity, Availability, Authentication, Non-repudiation
What is the definition of assurance? The best we can do towards security given our resources, considering the
value of our data, to have confidence in our security process
What are the three sides of the McCumber Model? Top: CIA | Right: Processing, Storage, Transmission | Left: Education, Policy &
Practice, Technology
What are threats to data in processing? Meltdown/Spectre, electronic side channels (Tempest), CPUs that aren't yours
What are threats to data in storage? Physical loss, unauthorized browsing
What are threats to data in transport? Eavesdropping, USB devices, theft or loss

What is the security cycle? Protect → Detect → Respond
What is the NIST Cybersecurity Framework? Identify → Protect → Detect → Respond → Recover
What is a true positive in detection? Someone is breaking in and the alarm sounds
What is a false positive in detection? No one is breaking in but the alarm sounds
What is a false negative in detection? Someone is breaking in but no alarm sounds
What is sensitivity? TP / (TP + FN) — percentage of time the system detects what it's looking for
What is specificity? TN / (TN + FP) — percentage of time it correctly ignores what it's not looking
for
What is Positive Predictive Value (PPV)? TP / (TP + FP) — percentage of alerts that are actually correct
