摘要:

信息系统使许多组织过程在每个行业。信息技术使用的效率和有效性产生了一个意想不到的副产品:现有用户或冒充他们的人滥用-内部威胁。如果对电子日志进行彻底分析,捕获用户行为,则可以检测内部威胁。然而,日志通常非常大且非结构化,给组织带来了重大挑战。在这项研究中,我们使用深度学习,特别是长短期记忆(LSTM)循环网络来实现检测。我们通过一个非常大的匿名数据集演示了LSTM如何使用数据的序列性质来减少搜索空间,并使安全分析师的工作更有效。

英文摘要:

Information systems enable many organizational processes in every industry. The efficiencies and effectiveness in the use of information technologies create an unintended byproduct: misuse by existing users or somebody impersonating them - an insider threat. Detecting the insider threat may be possible if thorough analysis of electronic logs, capturing user behaviors, takes place. However, logs are usually very large and unstructured, posing significant challenges for organizations. In this study, we use deep learning, and most specifically Long Short Term Memory (LSTM) recurrent networks for enabling the detection. We demonstrate through a very large, anonymized dataset how LSTM uses the sequenced nature of the data for reducing the search space and making the work of a security analyst more effective.
