Run-time malware detection strategies are efficient and robust, which get more and more attention. In this paper, we use I/O Request Package (IRP) sequences for malware detection. N-gram will be used to analyze IRP sequences for feature extraction. Integrated negative selection algorithm (NSA) and Positive selectionalgorithm (PSA), through a selection of n-gram sequences which only exist in malware IRP sequences, we have more than 96% true positive rate and 0% false positive rate.

In this, artificial immune system based approach;a set of fault detectors is generated using negative selection algorithm which is responsible for detecting faulty behavior of system. The idea is based on the self-non self-discrimination observed in biological immune system. The feasibility of scheme is implemented on sensors of simulated mobile robot.

A novel detector generation algorithm for Real-Valued negative selection algorithms, i.e. the PTS-RNSA, is proposed in this paper, which is based on the iterative Partition-Test-Spread process. Different from traditional detector generation algorithms that are randomized algorithms, the PTS-RNSA is a deterministic algorithm. When the number of the detectors is large enough, the PTS-RNSA can ensure to cover the whole non-self space except the boundary area between the self space and the non-self space. Experiments are done to compare the PTS-RNSA with the state-of-the-art algorithm, i.e. the V-detector algorithm. Experimental results demonstrate that the performance of the PTS-RNSA is very competitive. Especially, the time cost of the PTS-RNSA is much better than the V-detector algorithm.

negative selection algorithm (NSA) is an important detectors training algorithm in artificial immune system (AIS). In NSAs, the self radius and location of detectors affect the performance of algorithms. However, the traditional NSAs preset the self radius empirically and generate detectors randomly without considering the distribution of antigens resulting in the performance of AIS varies greatly in different applications. To deal with these limitations, an adaptive immunoregulation based real value negative selection algorithm (AINSA) is proposed in this paper. AINSA utilizes the "adaptive immunoregulation" mechanism to calculate the self radius and optimize the location of the candidate detectors. In this way, AINSA can attain the suitable self radius for different application and effectively generate the detectors in the region where antigens distribute densely. The experimental results show, on the artificial dataset and the UCI standard datasets, AINSA can reach the higher detection rate with better detectors generation efficiency compared to the classical RNSA and V-detector algorithm.

Intrusion detection systems could rely on short sequences of system calls to distinguish between legitimate and illegitimate activities. We found that the frequencies of system calls in a particular process generally follow the Zipf's law. It means that there are many sequences which are meaningless to differentiate the ongoing behavior but generate lots of computing waste. Due to improve the performance of existing intrusion detection methods which are implemented in the kernel of operating system, this paper focuses on the negative selection algorithm using maximum entropy model to avoid the degeneration caused by the Valueless repetition of system calls. The improved scheme uses negativeselection method to remove the useless computing which is predicted by maximum entropy model. Experimental results demonstrate that the computing cost has a reduction of 50 similar to 80% with the same Detection Rate

Real-value based negative selection algorithm (NSA) is an important detector generation algorithm of Artificial Immune System. Traditional real-value based negative selection algorithm generates immune detectors randomly and does not consider the sample distribution, therefore too many candidate detectors overlap in the feature space resulting in excessive redundancy. This leads to a low efficiency of detector generation and decreases the performance of NSA. To aim at this problem, the paper proposes a novel real-value negative selection algorithm based on Delaunay triangulation (dnyNSA). Firstly, dnyNSA uses Delaunay triangulation method to analyze the topological structure of training dataset and produces a set of simplicial cells (triangle in 2-dimensional space and tetrahedron in 3-dimensional space, etc.). Then, based on the simplicial cell circum-circle(-sphere) property, dnyNSA generates detectors in more reasonable position and size. Therefore, it only needs a small number of detectors to cover the same feature space, avoiding the generation of redundant detectors in traditional random mode, which greatly improves the efficiency of NSA. Theoretical analysis showed the time complexity of dnyNSA is in logarithmic level. The experimental results showed that, compared with the RNSA and V-Detector, dnyNSA can raise the detector generation efficiency over ten times while maintain similar detection performance.

Traditional negative selection algorithms do not perform any differentiation for training self dataset and only use the mechanism of negativeselection. They will generate excessive invalid detectors and have poor detection performance when the training selves contain noisy data. In this paper, an outlier robust algorithm is proposed. The new algorithm will divide the training selves into internal selves, boundary selves and outlier selves. At the same time, the information hiding in different kind of selves is fully utilized. Furthermore, by combining negativeselection mechanism with positive selection mechanism, the new algorithm can cover the non-self region more effectively. The experiment results show that no matter the training self data is clean or not, the new algorithm can obtain better detection performance by using fewer detectors.

As one of the most common and aggressive means, denial-of-service (DoS) attacks cause serious impact on computing systems and networks. This paper presents a system for detecting denial of service (DoS) attacks in a network using a combination of the dendritic cell algorithm (DCA) and the negative selection algorithm (NSA). The proposed system classifies incoming network traffic into either of two classes: "normal" or "DoS attack." Experimentally, our approach follows a majority voting technique by creating multiple instances of the DCA and the NSA algorithm and assigning weights to their respective output. The effectiveness of our proposed detection system is evaluated using an in-house generated signal dataset. Our results show that our system is very effective in detecting DoS/DDoS attacks with very high accuracy. Analysis of the proposed DoS detection system is also presented.
