在过去的十年里，网络犯罪一直是公众关注的焦点。然而，在犯罪学领域内，以前没有开展过研究活动，试图利用计算机网络数据更好地理解这一现象。为了应对这一挑战，我们采用了经典的日常活动和生活方式的观点，提出了针对大型大学计算机网络的计算机犯罪事件（即计算机利用，端口扫描和拒绝服务（DoS）攻击）的趋势和起源的假设。我们首先提出，针对大学网络的计算机犯罪是由大学用户的日常活动模式决定的。此外，我们假设网络用户的社会构成决定了针对大学网络的计算机攻击的起源。我们使用入侵防御系统（IPS）在2007年至2009年间记录的数据来验证这些说法。与我们的理论预期一致，出现了两个重要的发现。首先，计算机攻击更有可能发生在大学的正式营业时间。其次，外国网络用户数量的增加大大增加了源自与这些用户原籍国有关的互联网协议（IP）地址的以计算机为中心的犯罪数量。讨论了今后的研究方向。
Cybercrime has been the focus of public attention during the last decade. However, within the criminological field, no prior research initiatives have been launched in an effort to better understand this phenomenon using computer network data. Addressing this challenge, we employ the classical routine-activities and lifestyle perspective to raise hypotheses regarding the trends and origin of computer-focused crime incidents (i.e. computer exploits, port scans, and Denial of Service (DoS) attacks) against a large university computer network. We first propose that computer-focused crimes against a university network are determined by the university users’ daily activity patterns. In addition, we hypothesize that the social composition of the network users determines the origin of computer attacks against the university network. We use data recorded between the years 2007 and 2009 by an Intrusion Prevention System (IPS) to test these claims. Consistently with our theoretical expectations, two important findings emerge. First, computer attacks are more likely to occur during university official business hours. Second, an increase in the number of foreign network users substantially increases the number of computer-focused crimes originating from Internet Protocol (IP) addresses linked with these users’ countries of origin. Future directions for subsequent studies are discussed.
