Distributed Denial of Service (DDoS) is a serious computer network attack which can cause extreme performance degradation on the victim server. This paper presents a formal and methodical way of modeling DDoS attack by the method of Augmented Attack Tree (AAT), and presents an AAT-based attack detection algorithm. This modeling explicitly captures the particular subtle incidents triggered by DDoS...
The SQL injection attacks (SQLIAs) vulnerability is extremely widespread and poses a serious security threat to web applications with built-in access to databases. The SQLIA adversary intelligently exploits the SQL statement parsing operation by web servers via specially constructed SQL statements that subtly lead to non-explicit executions or modifications of corresponding database tables. In this...
Network attacks occur in high proportion on the internet, thus aside from security as a means of defense there is a need for being able to detect attacks as they occur so that measures can be put in place to tackle them. For this, an intrusion detection system (IDS) is required that has good quality of detection capability. We propose Quality of Detectability (QoD) as a kind of Quality of Service...
