THE SURVEILLANCE OF INTRUSION DETECTION SYSTEMS AND APPROACHES

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

Approaches 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...

Intrusion Detection: Techniques and Approaches

Intrusion detection plays one of the key roles in computer system security techniques. This paper is dedicated to this topic. It describes major approaches to intrusion detection and focuses on methods used by intrusion detection systems. We do not describe in this paper details of existing intrusion detection system. Instead, we concentrate on underlying principles and methods. This paper can ...

Intrusion detection techniques and approaches

Recent security incidents and analysis have demonstrated that manual response to such attacks is no longer feasible. Intrusion Detection systems offer techniques for modelling and recognising normal and abusive system behaviour. Such methodologies include: statistical models, immune system approaches, protocol verification, file and taint checking, neural networks, whitelisting, expression matc...
