Hinweis der Redaktion
- A decade ago, the Internet was something only “techies” talked about. It was a new limitless source of information, with very few users. Today, the Internet has already become an essential part of our lives. It’s where we access our banking records, credit card statements, tax returns and other highly sensitive personal information. By the end of this decade, over 2 billion people will be connected to the Internet—that’s about half the world’s current population.
- Reconnaissance: Reconnaissance is probably the longest phase, sometimes lasting weeks or months. The black hat uses a variety of sources to learn as much as possible about the target business and how it operates, including Scanning: Once the attacker has enough information to understand how the business works and what information of value might be available, he or she begins the process of scanning perimeter and internal network devices looking for weaknesses, including Gaining Access: Gaining access to resources of victim and extract information of value to the hacker or use his network as a launch site for attacks against other targets. In either situation, the attacker must gain some level of access to one or more network devices. Maintaining Access : Having gained access, an attacker must maintain access long enough to accomplish his or her objectives. Covering Tracks : After achieving his or her objectives, the attacker typically takes steps to hide the intrusion and possible controls left behind for future visits.
