Goosewolf: An Embedded Intrusion Detection System for Advanced Programmable Logic Controllers

Critical infrastructures are making increasing use of digital technology for process control. While there are benefits, such as increased efficiency and new functionality, digitalization also introduces the risk of cyber-attacks to systems that support critical functions. A valuable target in these Industrial Control Systems (ICSs) are the Programmable Logic Controllers (PLCs) controlling the machinery that manages a physical process. PLCs have proven to be vulnerable to a range of cyber-attacks in the past; however, newer technologies such as embedded servers and virtualization have the potential to improve this situation and be used to monitor a PLC’s function. In this article, the implementation of a Host-based Intrusion Detection System (HIDS) for a modern PLC is described. This method uniquely makes use of native technologies on the PLC to monitor a dynamic simulated process in real time. Both the PLC’s integrity (checksum, file size, etc.) and the process control are monitored to determine whether the PLC has been compromised in a cyber-attack. The proposed solution detects a range of attacks, even when the PLC’s control logic is compromised and—unlike previous PLC HIDS methods—requires no modification of the underlying PLC technology.

Host-based intrusion detection with multi-datasource and deep learning

Modern hackers display increasing sophistication. Intrusion detection systems, both network-based and host-based, now utilize machine learning for improved detection of such advanced attacks. While most of these systems rely on a single data source for training, practical scenarios often involve attack features scattered across multiple sources, posing challenges to the system’s effectiveness in detection. This impairs their potential for attack detection. Thus, this study assesses three host-based data sources—network traffic, system logs, and host statistics. It evaluates and compares their combined detection capabilities across diverse attack stages and types. In the proposed framework, network traffic data is handled by a Convolutional Neural Network (CNN) for improved automatic feature selection. System log data are processed using Long Short-Term Memory (LSTM) and an attention model to enhance temporal relationship exploration. Host statistics are processed by a Deep Neural Network (DNN) to improve classification performance. Experimental results show that the F1-scores reach 1.0 for all considered attacks and attack stages when all three data sources are utilized in the detection process. Additionally, employing diverse models based on the data type leads to improved results, a fact exemplified by Lin et al. (2022) which exclusively utilized XGBoost. The host statistics were found to be highly effective in detecting attacks and were thus investigated further for different attack methods and attack stages. The results showed that the disk usage percentage (DSK), minor memory faults (MINFLT), major memory faults (MAJFLT), total virtual memory growth during the last interval (VGROW), and total resident memory growth during the last interval (RGROW) were primarily affected by all the attacks in the initial access and command and control stages. By contrast, in the impact attack stage, the affected system resources varied widely depending on the particular attack.

Real-time anomaly attack detection based on an improved variable length model

This paper uses a real-time anomaly attack detection based on improved variable length sequences and data mining. The method is mainly used for host-based intrusion detection systems on Linux or Unix platforms which use shell commands. The algorithm first generates a stream of command sequences with different lengths and subsumes them into a generic sequence library, de-duplicats and sortes shell command sequences. The shell command sequences are then stratified according to their weighted frequency of occurrence to define the state. Next, the behavioural patterns of normal users are mined to output the state stream and a Markov chain is constructed. Then, the state sequences are calculated based on a primary probability distribution and a transfer probability matrix. The System will check decision values of the short sequence stream. Finally, the decision values of the behavioural sequences are analysed to determine whether the current session user is behaving abnormally. The improved algorithm introduces the concept of multi-order frequencies and proposes a new separation mechanism. The extension module is integrated into the variable length model. By comparing the performance of the old and new separation mechanisms on the SEA dataset and the self-made dataset (SD), it is found that the improved model greatly improves the performance of the model and shortens the running time.

SWMAT: Mel-frequency cepstral coefficients-based memory fingerprinting for IoT devices

The increasing sophistication in computing capability and sensing technologies have continued to drive the design, development, and growth of the smart technologies commonly known as the IoTs. Nonetheless, the rise and spread of malware in this ecosystem is a pressing societal concern that requires immediate attention. In this paper, we propose a novel technique called Sound Wave Memory Analysis Technique (SWMAT), for fingerprinting IoT devices by converting their dynamic memory traces into sound wave signals using a lossless transformation function from which a unique set of determinable features called Mel Frequency Cepstral Coefficients (MFCCs) are extracted. The overarching objective of this research is to explore offline the effectiveness of using features from memory-encoded sound wave signals for fingerprinting and detecting abnormal changes in IoT devices, which potentially can provide an excellent technique for an on-device Host-Based Intrusion Detection System. Our SWMAT scores the similarity between two sequences of MFCCs using a Dynamic Time Warping distance measure. To evaluate our approach, we developed multiple IoT testbeds and generated 125 MFCC sequences from 20 benign and 5 infected IoT applications. Our results showed that the MFCC features, when leveraged as fingerprints for both Intra and Inter-app similarity, can uniquely distinguish an IoT process and can detect when an IoT process has been hijacked and/or is modified by another malicious code. Furthermore, this empirical result shows our technique’s similarity detection accuracy to be ≈95%.

DongTing: A large-scale dataset for anomaly detection of the Linux kernel

Host-based intrusion detection systems (HIDS) can automatically identify adversarial applications by learning models from system events that represent normal system behaviors. The system call is the only way for applications to interact with the operating system (OS). Thus, system call sequences are traditionally used in HIDS to train models to detect novel attacks, and a wide range of datasets has been proposed for this task. However, existing datasets are either built for user-level applications (not for OS kernels), or completely outdated (proposed more than 20 years ago). To address this issue, this paper presents the first large-scale dataset specifically assembled for anomaly detection of the Linux kernel.The task of creating such a dataset is challenging due to the difficulty both in collecting a diversified set of programs that can trigger bugs in the kernel and in tracing events that may crash the kernel at runtime. In this paper, we describe in detail how to collect the data through an automated and efficient framework. The raw dataset is 85 GB in size, and contains 18,966 system call sequences that are labeled with normal and abnormal attributes. Our dataset covers more than 200 kernel versions (including major/minor releases and revisions) and 3,600 bug-triggering programs in the past five years. In addition, we conduct cross-dataset evaluation to demonstrate that training on our dataset enables superior generalization ability than other related datasets, and provide benchmark results for anomaly detection of Linux kernel on our dataset. Our extensive dataset is both useful for machine learning researchers focusing on algorithmic optimizations and practitioners in kernel development who are interested in deploying deep learning models in OS kernels.

Towards a better similarity algorithm for host-based intrusion detection system

Abstract An intrusion detection system plays an essential role in system security by discovering and preventing malicious activities. Over the past few years, several research projects on host-based intrusion detection systems (HIDSs) have been carried out utilizing the Australian Defense Force Academy Linux Dataset (ADFA-LD). These HIDS have also been subjected to various algorithm analyses to enhance their detection capability for high accuracy and low false alarms. However, less attention is paid to the actual implementation of real-time HIDS. Our principal objective in this study is to create a performant real-time HIDS. We propose a new model, “Better Similarity Algorithm for Host-based Intrusion Detection System” (BSA-HIDS), using the same dataset ADFA-LD. The proposed model uses three classifications to represent the attack folder according to certain criteria, the entire system call sequence is used. Furthermore, this work uses textual distance and compares five algorithms like Levenshtein, Jaro–Winkler, Jaccard, Hamming, and Dice coefficient, to classify the system call trace as attack or non-attack based on the notions of interclass decoupling and intra-class coupling. The model can detect zero-day attacks because of the threshold definition. The experimental results show a good detection performance in real-time for Levenshtein/Jaro–Winkler algorithms, 99–94% in detection rate, 2–5% in false alarm rate, and 3,300–720 s in running time, respectively.

Evaluating Word Embedding Feature Extraction Techniques for Host-Based Intrusion Detection Systems

Research into Intrusion and Anomaly Detectors at the Host level typically pays much attention to extracting attributes from system call traces. These include window-based, Hidden Markov Models, and sequence-model-based attributes. Recently, several works have been focusing on sequence-model-based feature extractors, specifically Word2Vec and GloVe, to extract embeddings from the system call traces due to their ability to capture semantic relationships among system calls. However, due to the nature of the data, these extractors introduce inconsistencies in the extracted features, causing the Machine Learning models built on them to yield inaccurate and potentially misleading results. In this paper, we first highlight the research challenges posed by these extractors. Then, we conduct experiments with new feature sets assessing their suitability to address the detected issues. Our experiments show that Word2Vec is prone to introducing more duplicated samples than GloVe. Regarding the solutions proposed, we found that concatenating the embedding vectors generated by Word2Vec and GloVe yields the overall best balanced accuracy. In addition to resolving the challenge of data leakage, this approach enables an improvement in performance relative to other alternatives.

An Artificial Neural Network Technique for Prediction of Cyber-Attack using Intrusion Detection System

An intrusion detection system, often known as IDS, is a piece of equipment or a piece of software that monitors a network or collection of devices in order to search for indications of possible intrusion. The frequency of cyber assaults has grown in recent years, and with it, the damage they do to society. The study of cyber security and the avoidance of cyber assaults, such as the use of intrusion detection as a defensive mechanism, is therefore needed. The internet services are widely used. Services based on computers, the internet, and other forms of technology are all considered part of the cyber world. The cyber world has advanced greatly thanks to new protocols and technologies. Cyber security is a major issue for every service that operates online. Network and host-based intrusion detection systems (NIDS/HIDS) are the backbones of any cyber security infrastructure. The NSL-KDD dataset is often used in algorithm research and verification and is widely employed in both the study and development of intrusion detection systems. In this study, we provide a neural network approach to intrusion detection system threat prediction. In this paper, the Python Spyder software is used for the simulation.

Robust Design and Implementation of a Network IntrusionDetection System

A Network Intrusion Detection System (NIDS) is an essential component of network security that helps to identify and responds to potential security branches and attacks within a network infrastructure. Computer security has become a challenge and various tools and mechanisms have been developed in order to guarantee a safety level up to the requirements of modern life. Information security is of great concern these days due to the activities of hackers and malicious users on the Internet. Securing informationhas become a critical issue and is of growing concern as computer systems worldwide become increasingly vulnerable to the rapid increase in the volume of information being transmitted across networks and over the Internet. It describes various approaches of detecting the attacks and preventing the attacks with different techniques such as pattern matching, protocol decoding, defining rules and signatures etc. This research work introduced a technique which provided a robust intrusion detection system against attackers. The framework consists of a Network Intrusion Detection System (NIDS) for detection of traffic to and from a given network, a Host based Intrusion Detection System (HIDS) and a line for possible Intrusion Prevention Systems (IPS). The technique was developed by modeling network using a network simulation software; since a real life implementation is very costly. The result showed that the technique provided an intrusion detection system that can be used to monitor user’s activities on the Internet and other networks with relatively minimal error.

Developing Cross-Domain Host-Based Intrusion Detection

Digital transformation has continued to have a remarkable impact on industries, creating new possibilities and improving the performance of existing ones. Recently, we have seen more deployments of cyber-physical systems and the Internet of Things (IoT) as in no other time. However, cybersecurity is often an afterthought in the design and implementation of many systems; therefore, there usually is an introduction of new attack surfaces as new systems and applications are being deployed. Machine learning has been helpful in creating intrusion detection models, but it is impractical to create attack detection models with acceptable performance for every single computing infrastructure and the various attack scenarios due to the cost of collecting quality labeled data and training models. Hence, there is a need to develop models that can take advantage of knowledge available in a high resource source domain to improve performance of a low resource target domain model. In this work, we propose a novel cross-domain deep learning-based approach for attack detection in Host-based Intrusion Detection Systems (HIDS). Specifically, we developed a method for candidate source domain selection from among a group of potential source domains by computing the similarity score a target domain records when paired with a potential source domain. Then, using different word embedding space combination techniques and transfer learning approach, we leverage the knowledge from a well performing source domain model to improve the performance of a similar model in the target domain. To evaluate our proposed approach, we used Leipzig Intrusion Detection Dataset (LID-DS), a HIDS dataset recorded on a modern operating system that consists of different attack scenarios. Our proposed cross-domain approach recorded significant improvement in the target domains when compared with the results from in-domain approach experiments. Based on the result, the F2-score of the target domain CWE-307 improved from 80% in the in-domain approach to 87% in the cross-domain approach while the target domain CVE-2014-0160 improved from 13% to 85%.

SEHIDS: Self Evolving Host-Based Intrusion Detection System for IoT Networks.

The Internet of Things (IoT) offers unprecedented opportunities to access anything from anywhere and at any time. It is, therefore, not surprising that the IoT acts as a paramount infrastructure for most modern and envisaged systems, including but not limited to smart homes, e-health, and intelligent transportation systems. However, the prevalence of IoT networks and the important role they play in various critical aspects of our lives make them a target for various types of advanced cyberattacks: Dyn attack, BrickerBot, Sonic, Smart Deadbolts, and Silex are just a few examples. Motivated by the need to protect IoT networks, this paper proposes SEHIDS: Self Evolving Host-based Intrusion Detection System. The underlying approach of SEHIDS is to equip each IoT node with a simple Artificial Neural Networks (ANN) architecture and a lightweight mechanism through which an IoT device can train this architecture online and evolves it whenever its performance prediction is degraded. By this means, SEHIDS enables each node to generate the ANN architecture required to detect the threats it faces, which makes SEHIDS suitable for the heterogeneity and turbulence of traffic amongst nodes. Moreover, the gradual evolution of the SEHIDS architecture facilitates retaining it to its near-minimal configurations, which saves the resources required to compute, store, and manipulate the model’s parameters and speeds up the convergence of the model to the zero-classification regions. It is noteworthy that SEHIDS specifies the evolving criteria based on the outcomes of the built-in model’s loss function, which is, in turn, facilitates using SEHIDS to develop the two common types of IDS: signature-based and anomaly-based. Where in the signature-based IDS version, a supervised architecture (i.e., multilayer perceptron architecture) is used to classify different types of attacks, while in the anomaly-based IDS version, an unsupervised architecture (i.e., replicator neuronal network) is used to distinguish benign from malicious traffic. Comprehensive assessments for SEHIDS from different perspectives were conducted with three recent datasets containing a variety of cyberattacks targeting IoT networks: BoT-IoT, TON-IOT, and IoTID20. These results of assessments demonstrate that SEHIDS is able to make accurate predictions of 1 True Positive and is suitable for IoT networks with the order of small fractions of the resources of typical IoT devices.

Improving the efficiency of intrusion detection in information systems

Abstract Policy Interaction Graph Analysis is a Host-based Intrusion Detection tool that uses Linux MAC Mandatory access control policy to build the licit information flow graph and uses a detection policy defined by the administrator to extract illicit behaviour from the graph. The main limitation of this tool is the generation of a huge signature base of illicit behaviours; hence, this leads to the use of huge memory space to store it. Our primary goal in this article is to reduce this memory space while keeping the tool’s efficiency in terms of intrusion detection rate and false generated alarms. First, the interactions between the two nodes of the graph were grouped into a single interaction. The notion of equivalence class was used to classify the paths in the graph and was compressed by using a genetic algorithm. Such an approach showed its efficiency compared to the approach proposed by Pierre Clairet, by which the detection rate obtained was 99.9%, and no false-positive with a compression rate of illicit behaviour signature database reached 99.44%. Having these results is one of the critical aspects of realizing successful host-based intrusion detection systems.

Host-based intrusion detection system using Support Vector Machine

In line with the communication industry’s use of recent advancements in network technology to link remote areas of the world, attackers or intruders have stepped up their attacks on networking infrastructure. System administrators might deploy intrusion detection tools and systems to thwart such efforts. In recent years, the use of machine learning (ML) techniques in intrusion detection systems (IDSs) has increased. One of the most popular machine learning (ML) techniques for intrusion detection is the Support Vector Machine (SVM) due to its excellent generalization and capacity to escape the dimensionality curse. Recent studies have shown that the number of dimensions still impacts how well SVM-based intrusion detection systems work. The fact that SVM assesses all data characteristics equally has also caused some concerns. Actual intrusion detection datasets include a lot of redundant or superfluous characteristics. It would be ideal to consider feature weights while training an SVM. Knowledge Discovery in Databases (KDD) intrusion detection dataset offers labeled data for the scientists and researchers; choosing the essential features or patterns from the input dataset makes the problem more straightforward and faster and acquires much more accuracy towards threat detection. Our work demonstrates the efficiency of recognizing the essential input patterns to design a more efficient Intrusion Detection System (IDS). Consequently, removing irrelevant or unimportant inputs makes the problem of detecting a threat simpler, faster, and more accurate. It has been an essential issue in intrusion detection that features selection and ranking must be made accordingly; it is the only way to detect intrusion accurately and efficiently. We implement the procedure to remove one feature at a time to run experiments on a Support Vector Machine (SVM) to grade the significance of the features for the KDD dataset. It has been observed that SVM-based IDSs utilizing fewer features could improve and efficiently perform.

An Intrusion Detection System Using SDAE to Enhance Dimensional Reduction in Machine Learning

In the last decade, the number of attacks on the internet has grown significantly, and the types of attacks vary widely. This causes huge financial losses in various institutions such as the private and government sectors. One of the efforts to deal with this problem is by early detection of attacks, often called IDS (instruction detection system). The intrusion detection system was deactivated. An Intrusion Detection System (IDS) is a hardware or software mechanism that monitors the Internet for malicious attacks. It can scan the internetwork for potentially dangerous behavior or security threats. IDS is responsible for maintaining network activity under the Network-Based Intrusion Detection System (NIDS) or Host-Based Intrusion Detection System (HIDS). IDS works by comparing known normal network activity signatures with attack activity signatures. In this research, a dimensional reduction and feature selection mechanism called Stack Denoising Auto Encoder (SDAE) succeeded in increasing the effectiveness of Naive Bayes, KNN, Decision Tree, and SVM. The researchers evaluated the performance using evaluation metrics with a confusion matrix, accuracy, recall, and F1-score. Compared with the results of previous works in the IDS field, our model increased the effectiveness to more than 2% in NSL-KDD Dataset, including in binary class and multi-class evaluation methods. Moreover, using SDAE also improved traditional machine learning with modern deep learning such as Long Short-Term Memory (LSTM) and Convolutional Neural Network (CNN). In the future, it is possible to integrate SDAE with a deep learning model to enhance the effectiveness of IDS detection

An AI powered system call analysis with bag of word approaches for the detection of intrusions and malware in Australian Defence Force Academy and virtual machine monitor malware attack data set

AbstractThis study propose the use of AI enabled machine learning algorithms with the Bag‐of‐Word (BoW) methods for the detection of intrusions by analysing the system call patterns. Host based Intrusion Detection System can make use of system call patterns to differentiate between normal and anomalous program behaviours. First, the system call patterns are pre‐processed with different approaches like BoW, BoW with Boolean value, BoW with Probability value and BoW with TF‐IDF. Next machine learning algorithms are used to evaluate the performance of classifier models. We used J48 (C4.5), Random Forrest, RIPPER, KNN, SVM, and NaiveBayes ML algorithms. This process was carried out on ADFA‐LD and on our proposed virtual machine monitor (VMM) malware attack data set for analysis. The proposed work is evaluated based on detection accuracy and false alarm rate metrics. Random Forrest algorithm performs better compared with other ML algorithms in terms of intrusion detection accuracy and false alarm rate on ADFA and VMM malware data set. The proposed data set provide better results compared with ADFA‐LD analysed using ML algorithms. The classifier model trained with ADFA and VMM malware system call data sets may do predictive analytics in detecting security issues for Industry 4.0 systems.

Multiclass cyber-attack classification approach based on the Krill Herd Optimized Deep Neural Network (KH-DNN) model for WSN

The Intrusion Detection System (IDS) is a useful infiltration detection tool. With IDS, it may mechanically categorize intrusions, attacks, or breaches of security stratagems across host-level within the network and within the organization. The Krill Herd Optimized Deep Neural Network (KH-DNN) is proposed in this document as a multiclass cyberattack methodology. This model is suggested by uniting the network-based intrusion detection system (NIDS) and the host-based intrusion detection system (HIDS) to advance flexible and actual IDS to categorize and detect unexpected and unpredictable cyber attacks. In this method, two types of IDS are classified, that is, NIDS and HIDS. Classification of the system call is exploited to discriminate behavior into normal and attack categories. In this manuscript accuracy, the parameter of the deep neural network classifier is optimized with the Krill Herd optimization algorithm. Finally, the DNN model is performed in the NIDS dataset and the HIDS dataset. For the HIDS dataset, the KDD Cup 99 dataset was used, which employed two datasets: ADFA-LD and ADFA-WD, and several types of attacks were detected and classified, including Adduser, Hydra-FTP, Java-Meterpreter, Hydra-SSH, and Web-Shell. The suggested IDS-KH-DNN algorithm attains higher accuracy 42.56% and 23.4%, high precision 84.74% and 52.43%, high F-score 53.5% 64.455, high sensitivity 33.4% and 45.23%, and high specificity 31.45% and 44.23% for the NIDS dataset. The proposed system is compared to two current processes: intrusion detection using Gray Wolf optimization-based support vector machine (IDS-GWO-SVM) and intrusion detection using artificial bee colony optimization algorithm based support vector machine (IDS-ABCO-SVM). Finally, the simulation results show that the suggested approach is capable of quickly and accurately locating optimal solutions.

Process Aware Host-based Intrusion Detection Model

Nowadays, many organizations use Process Aware Information Systems (PAISs) to automate their business process. As any other information systems, security plays a major role in PAIS to provide a secure state and maintain the system in it. In order to provide security in a PAIS, a Process Aware Host-based Intrusion Detection (PAHID) model is proposed in this paper. The model detects host-based intrusions in a PAIS using process mining techniques.The proposed model uses both anomaly detection and misuse detection techniques for more efficiency, and organizational perspective of process mining is considered (rather than control-flow perspective) to detect more attack types. The model is automated and can deal with large logs and is suitable for flexible application domains. The PAHID model is implemented by the use of ProM framework and Java programming. It is evaluated by using a simulated log based on a real-world organization information system. Results demonstrate that the model provides high accuracy and low false positive rate.

Comparison of the Host Based Intrusion Detection Systems and Network Based Intrusion Detection Systems

Recently, Advanced Persistent Threat (APT) has emerged as sophisticated and tailor-made attacks. APTs pose threats mainly targeting institutions such as military, defense and security infrastructure, high profile companies and governments etc. Particularly as a counter measure for APT attacks done by hactivists and cyber warriors and cyber terrorists over government institutions and e-government applications intrusion detection mechanisms are of crucial importance in effective defense. In this study, Intrusion detection and prevention systems have been studied in detail after being referred to the tasks and abilities of the intrusion detection systems that are at the core of the computer security technology presented today in order to meet the increasing need for information and network security. This paper’s aim is the specifying the differences between Host Based Intrusion Detection Systems (HIDS) and Network Based Intrusion Detection Systems (NIDS) and compares the tools which are using HIDS and NIDS. It is asserted that in order to have a better assurance for APT attacks there should be set up a Hybrid IDS approach covering both networks and hosts using both signature and behavioral detection mechanism based on machine learning.
