Security video
• Concept of a burglar choosing a house and will get deterred looing secure
• Online – how would a hacker decide what to hack?

Digitizing security
• What does the digital space offer us?
o How you store a diamond?
▪ Security cameras, monitor, bury it, a safe, a wall
o You would look at multiple layers of security in the digital security
▪ Encryption, servers, monitoring
▪ Easiest way to infiltrate a digital system?
• Enter the facility
• People are the easiest to infiltrate
Big data
• Large amounts of data used to identify trends and patterns
• What is the difference between information and data?
o If you interpret it, it becomes information
o Ie. Data : 10101011001 → takeoff and landing pattern of an airport and becomes
information
• Data
o When you see patterns and you interpret it, then it becomes information
• Information
o When it has trends and patterns, it becomes knowledge
• Knowledge
o When you can use it in other disciplines, it becomes wisdom
• Wisdom
o Something actionable across all areas
Correlation does not mean causation

The big Vs of data
Velocity – the speed at which data is created
Volume – the amount of data that is created
Variety – the variety of data that is created
Ie → the geolocation of data for instance, as more ppl buy phones more data is produced and can include
call logs, messages etc.
Hacking in class
1. Ashley Madison

malware
c. Where was the digital divide?
i. Geography - the main application store in SF
ii. Money – people who cannot afford internet connection in San Francisco
Concepts highlighted ** test
Vertical and horizontal
• data moving between platforms : vertical
• data moving between applications: horizontal

associate your image/stage name/logo and find your performative presence
