Revisiting Anomaly-based Network Intrusion Detection Systems
Intrusion detection systems (IDSs) are well-known and widely-deployed security tools to detect cyber-attacks and malicious activities in computer systems and networks. A signature-based IDS works similar to anti-virus software. It employs a signature database of known attacks, and a successful match with current input raises an alert. A signature-based IDS cannot detect unknown attacks, either ...
متن کاملApproaches in anomaly-based intrusion detection systems
Anomaly-based network intrusion detection systems can take into consideration packet headers, the payload, or a combination of both. We argue that payload-based approaches are becoming the most effective methods to detect attacks. Nowadays, attacks aim mainly to exploit vulnerabilities at application level: thus, the payload contains the most important information to differentiate normal traffi...
متن کاملAnomaly-Based Intrusion Detection for SCADA Systems
Most critical infrastructure such as chemical processing plants, electrical generation and distribution networks, and gas distribution is monitored and controlled by Supervisory Control and Data Acquisition Systems (SCADA). These systems have been the focus of increased security and there are concerns that they could be the target of international terrorists. With the constantly growing number ...
متن کاملAssessment Methodology for Anomaly-Based Intrusion Detection in Cloud Computing
Cloud computing has become an attractive target for attackers as the mainstream technologies in the cloud, such as the virtualization and multitenancy, permit multiple users to utilize the same physical resource, thereby posing the so-called problem of internal facing security. Moreover, the traditional network-based intrusion detection systems (IDSs) are ineffective to be deployed in the cloud...
متن کاملTaxonomy of Anomaly Based Intrusion Detection System: A Review
Intrusion detection systems aim at detecting attacks against information systems in general. It is difficult to provide secure information systems and maintain them in a secure state for their entire lifetime. Maintenance of such information system is technically difficult as well as economically costly. With the advent of new vulnerabilities to information system new techniques for detecting t...
