- Virus (self replicates by attaching to another program or file)
- Worm (replicates independently of another program)

- Spyware (collects information from a target system)
- Adware (delivers advertisements with or without consent)
- Bot (waits for commands from the hacker)

2017 biggest threats,

some quotes from top managers about their view of perceived threats

"large-scale IoT security breach will occur in 2017

continued rise in popularity of connected products results in an increase in the number of back doors open to an adversary, and IoT devices will become a target for ransomware

DDoS attacks, internet shutdowns powered by cheap, insecure IoT devices will become more common

Successful attacks on IoT sensors are difficult to detect because of the limited access to the device's system state, insufficient computing power for endpoint protection software to be installed on them, and lack of security compliance standards for IoT security best practices."

The higher the privilege level, the more router access a user has. Commands that are available at lower privilege levels are also executable at higher levels. @ciscoAcademy
