Unsupervised intrusion detection model based on temporal convolutional network
现有的多数入侵检测模型通过长短期记忆(long short-term memory,LSTM)网络评估数据之间的时间依赖性。然而,LSTM网络处理序列数据增加了训练模型的计算复杂度和存储成本。为此,提出了基于多头注意力机制和时间卷积网络的无监督入侵检测模型(unsupervised intrusion detection model based on multi-head attention mechanism or temporal convolutional network,UDMT)。UDMT不依赖于LSTM网络,它利用时间卷积网络和多头注意力机制构建生成对抗网络的生成器和决策器,实现计算的并行化,进而降低复杂度。同时,UDMT不依赖于标签的攻击数据,它具有检测已知攻击和未知攻击的能力。此外,UDMT采用不同的隐藏层模式,配置灵活,以满足不同的检测率和检测时延的要求。相比于两个同类的检测模型,提出的UDMT能获取更高的检测率和更低的检测时延。
Abstract
Most existing intrusion detection models rely on long short-term memory (LSTM) networks to consider time-dependencies among data. However
LSTM’s sequential data processing significantly increases computational complexity and memory consumption during training. Therefore
unsupervised intrusion detection model based on multi-head attention mechanism and temporal convolutional network (UDMT) was proposed. UDMT didn’t rely on LSTM networks. Instead
it used temporal convolutional network and multi-head attention mechanism in the generative adversarial network generator and discriminator networks to enable more computation parallelization
and reduced computational complexity. Moreover
UDMT was capable of detecting both known and zero-day attacks without relying on labeled attack data. In addition
UDMT can adopt different privacy layer modes
and the configuration was flexible to meet the requirements of different detection rates and detection delays. Experiment results show that the proposed UDMT has higher detection rate and lower detection latency than two state-of-the-art intrusion detection models.
