....port scanning methods and attacks, there is very little broad understanding of intrusion activity on a global basis. Because of these challenges, current best practices for Internet security rely heavily on word of mouth reports of new intrusions and security holes through entities such as CERT [4] and DSHIELD [24] The focus of this paper is the development of a quantitative characterization of intrusion activity in the global Internet. To our knowledge, this is the first study to broadly address this problem using intrusion logs from firewalls at sites distributed throughout the ....
....executed [3] 4.1.3 Nimda Nimda stands for admin spelled backwards. The algorithm for target detection is not well known, but seems to follow these rough probabilities: 50 an IP address with same first 2 octets, 25 an IP address with matching first octet and 25 a completely random IP address [4]. Figure 2 shows the number of distinct sources scanning port 80 during the 3 months in 2002 from our dataset. The graph shows the predictable nature of the port 80 scans and also very strong day of the month characteristics. The sharp drop around the 19th of each month confirms that CodeRed I is ....
