大数据系统中内部攻击检测的系统架构

A System Architecture for the Detection of Insider Attacks in Big Data Systems

Santosh Aditham, Nagarajan Ranganathan

摘要:

在大数据系统中,基础设施使得大量数据远离用户托管。在这样的系统中,信息安全被认为是一个主要的挑战。从客户的角度来看,采用大数据系统的一个大风险是信任设计和拥有基础设施的提供商访问用户数据。然而,在文献中并没有太多关于检测内部攻击的内容。在这项工作中,我们提出了一个新的系统架构,其中内部攻击可以通过利用系统中的各个节点上的数据复制来检测。该系统使用两步攻击检测算法和安全通信协议来分析系统中执行的进程。第一步涉及为系统中的每个进程构造控制指令序列。第二步涉及在副本节点之间匹配这些指令序列。在实际的Hadoop和Spark测试中的初步实验表明,该系统只需要考虑20%的代码来分析程序,并产生3.28%的时间开销。由于其外在的工作流程,所提出的安全系统可以为任何大数据系统实现和构建。

英文摘要:

In big data systems, the infrastructure is such that large amounts of data are hosted away from the users. In such a system information security is considered as a major challenge. From a customer perspective, one of the big risks in adopting big data systems is in trusting the provider who designs and owns the infrastructure from accessing user data. Yet there does not exist much in the literature on detection of insider attacks. In this work, we propose a new system architecture in which insider attacks can be detected by utilizing the replication of data on various nodes in the system. The proposed system uses a two-step attack detection algorithm and a secure communication protocol to analyze processes executing in the system. The first step involves the construction of control instruction sequences for each process in the system. The second step involves the matching of these instruction sequences among the replica nodes. Initial experiments on real-world hadoop and spark tests show that the proposed system needs to consider only 20% of the code to analyze a program and incurs 3.28% time overhead. The proposed security system can be implemented and built for any big data system due to its extrinsic workflow.
