Keyloggers and System monitors are either commercial or non-commercial. A commercial system monitor is a piece of software with system monitor characteristics, obtained with a legitimate license by legal means. All other system monitors are non-commercial system monitors. The system monitor category encompasses any software that performs the following actions:

• Overtly or covertly records system processes and/or user actions
  
• Makes those records available for retrieval and review at a later time
  

These processes can include any action on a machine from the time it turns on to the time it turns off, such as:

• Time of power on
  
• Login information
  
• E-mail passwords
  
• Financial account information
  
• Credit card numbers
  
• Social security numbers
  
• Screenshots
  
• Phone numbers
  
• Addresses
  
• Keystrokes
  
• Webcam photos
  
• Sound
  
• Time of power off
  
• Any other computer activity
