What are the current limitations and challenges in detecting intrusions in computer networks?5 answersCurrent limitations and challenges in detecting intrusions in computer networks include the susceptibility of machine learning-based Intrusion Detection Systems (IDSs) to adversarial attacks. Additionally, the scarcity of labeled samples hinders the construction of accurate IDS models, prompting the need for transfer learning techniques. Moreover, existing IDSs struggle to adapt to evolving network traffic behaviors over time, necessitating reinforcement learning approaches with periodic model updates or sliding window mechanisms. Furthermore, the performance of IDSs significantly deteriorates when deployed on networks with different feature distributions from the training dataset, highlighting the need for domain adaptation techniques to enhance generalizability and mitigate distribution gaps.
What are the challenges in developing effective intrusion detection systems?4 answersDeveloping effective intrusion detection systems (IDSs) faces several challenges. Firstly, the availability of high-quality datasets for training IDS models is a problem. Many publicly available datasets do not accurately reflect real-world data, although they enable benchmarking. Secondly, current IDS models require large datasets for training, and their performance is highly dependent on dataset size. Additionally, the increasing rate and sophistication of cyber attacks make retraining time-consuming and impractical for practical implementation. Furthermore, the current approaches used in IDSs have limitations in detecting intrusions, which can affect the overall performance of the detection system and network performance. To address these challenges, new approaches such as learning from pair similarities and integrating blockchain technology into IDSs have been proposed. These approaches aim to reduce the burden of retraining, enhance overall performance, and leverage the properties of blockchain for improved security.
What are the biggest challenges faced in the past and today in cyber threat detection?5 answersThe biggest challenges faced in cyber threat detection include low detection rates, high rates of false alarms, adversarial resilience, big data issues, and the difficulty of handling and avoiding emerging threats.These challenges are further exacerbated by the continuously changing nature of cyber-attacks and the use of advanced attack and deception skills.Additionally, the use of reverse-engineered technology and modern tactics by attackers, along with the reliance on OSINT data collection tactics, pose significant challenges in identifying and mitigating cyber threats.The quality of vulnerability and threat identification is also affected by issues related to asset discovery, precision of vulnerability discovery, and the amount of data.Cooperation between standards from threat, vulnerability, and asset management is another unresolved issue in cyber threat identification.
What are the key challenges in intrusion detection for smart homes?5 answersThe key challenges in intrusion detection for smart homes include security breaches and vulnerabilities that can be exploited by external attacks. Conventional intrusion detection systems designed for traditional networks are not efficient in smart home environments due to resource-constrained devices and intermittent connectivity. The complex nature of artificial neural network (ANN) models used for intrusion detection makes it difficult for common users to trust ANN-based security solutions. Additionally, selecting the right hyperparameters for ANN architecture is crucial for accurate detection of security attacks. The changing conditions of smart homes, such as new devices and user interactions, require intrusion detection systems to adapt and adjust their decision functions. Ensuring the privacy and trustworthiness of smart home systems is also a significant challenge.
What are the main challenges in the design of intrusion-detection systems?1 answersThe main challenges in the design of intrusion-detection systems include the need for classifiers to be tuned and optimized for better performance. Additionally, the increasing sophistication of cyber-attacks poses a challenge in accurately detecting intrusions. Furthermore, the security of cloud computing and the identification of malicious entities and fake traffic are important issues that need to be addressed. Another challenge is the proper functionality and efficiency of current intrusion-detection and prevention systems, especially in the context of cloud computing, smart-phones, and smart cities. Finally, finding the optimal intrusion detection thresholds is a challenging task, especially when defending multiple inter-dependent computer systems against a strategic attacker.
What are the challenges and opportunities in the design of intrusion detection systems?5 answersIntrusion detection systems (IDSs) face challenges and opportunities in their design. IDSs can be signature-based, where known intrusion experiences are cross-checked with monitored events, or anomaly-based, where the normal behavior of the system is learned and anomalous events are reported. The application of IDS to Internet of Things (IoT) networks and the use of edge computing to support IDS implementation present new challenges. Device classification at the edge is leveraged by IDSs in IoT networks. Provenance-based intrusion detection, which provides a holistic view of system execution, offers opportunities for strengthening detection robustness. However, attackers constantly develop new attack vectors to evade IDSs, making intrusion detection an ongoing arms race. The design of IDSs must address these challenges and leverage the opportunities provided by provenance and edge computing.
