Particle Detectors. … is a device used to . detect, . track, and/or . identify high-energy particles [e.g., those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator]. . Intruders. Classes (from [ANDE80]:. two most publicized threats to security are malware and intruders. generally referred to as a . hacker. or . cracker. Examples of Intrusion. remote root compromise. Paper by: T. Bowen. Presented by: Tiyseer Al Homaiyd. 1. Introduction: . Intrusions: show observable events that deviate from the . norm.. Survivable system usually focus on detecting intrusions rather than preventing or containing damage. . Before deep . convnets. Using deep . convnets. PASCAL VOC. Beyond sliding windows: Region proposals. Advantages:. Cuts . down on number of regions detector must . evaluate. Allows detector to use more powerful features and classifiers. transmitted. absorbed. reflected. 1. transmission. Radiation passes through atmosphere unimpeded.. Shortwave and longwave “windows” . 2. absorption. Energy is transferred to absorber; absorber emits energy. modified from slides of . Lawrie. Brown. Classes of Intruders – Cyber Criminals. Individuals or members of an organized crime group with a goal of financial reward. Their activities may include: . What is an IDS?. An . I. ntrusion . D. etection System is a wall of defense to confront the attacks of computer systems on the internet. . The main assumption of the IDS is that the behavior of intruders is different from legal users.. 1. T. . Lefevre. on behalf of the Beam instrumentation group.
