Overview

Security studies strongly demonstrate that most systems will be attacked within 5 hours after becoming publicly accessible—in some cases, in less than 2 hours. The sources of the attacks are often unsuspecting users whose systems have been compromised by malware and are in turn being used to attack and infect other systems.

  1. A combination of commonly used system accounts (e.g., the root account) with weak, dictionary-based passwords
  2. Systems that are missing critical or high-security vulnerabilities
