Introduction

The continuous evolution of cyber threats, combined with the ever-increasing volume of data generated across networked systems, has brought about significant challenges in modern cybersecurity [1]. The need to detect and respond to potential security breaches in real-time is more critical than ever [2]. As organizations continue to integrate a growing array of connected devices, data sources, and platforms, the sheer volume and complexity of data being generated require sophisticated systems capable of processing and analyzing it instantaneously [3]. This rapid data influx introduces numerous difficulties in ensuring its accuracy, privacy, and scalability. For cybersecurity systems to be effective, they must process vast amounts of heterogeneous data in real time, identify anomalous behavior, and generate actionable insights within a fraction of a second [4]. This chapter explores the key challenges and solutions for handling time-sensitive cybersecurity data, focusing on the collection, preprocessing, feature engineering, and real-time processing of security-related information [5].

Data collection for cybersecurity systems is increasingly dependent on diverse sources, ranging from IoT devices and network traffic to system logs and user activity data [6]. Each of these data sources comes with its own unique challenges, such as inconsistent formats, varying levels of detail, and the need for fast, efficient collection methods [7]. As data flows in from these disparate systems, it must be aggregated, cleaned, and prepared for analysis [8]. The preprocessing of this data is critical, as the effectiveness of downstream analysis, such as intrusion detection or anomaly detection, relies heavily on the quality of the input data. In real-time cybersecurity environments, preprocessing must occur quickly, without introducing significant latency [9]. The raw data often needs to be validated, filtered for irrelevant information, and transformed into a suitable format for analysis, all of which require robust, automated processes to handle large-scale data streams efficiently. Only through these processes can cybersecurity systems effectively process data in real time while ensuring its accuracy and relevance [10].

While data collection and preprocessing are essential, one of the most pressing concerns in cybersecurity systems is the maintenance of data integrity [11]. As data is continuously ingested from various sources, there is an inherent risk of corruption, loss, or error [12]. Even a small flaw in the data can lead to incorrect conclusions or the failure to detect a critical incident, making robust error detection mechanisms a key part of any cybersecurity system. Effective real-time data validation is necessary to prevent compromised data from infiltrating the analysis pipeline [13]. Techniques such as anomaly detection, statistical validation, and consistency checks play a pivotal role in ensuring that only high-quality data is used for threat detection [14]. By employing automated validation techniques that can detect discrepancies or anomalies in real-time, cybersecurity systems can reduce the likelihood of false positives and ensure that the data being analyzed is accurate. Moreover, ensuring the integrity of the data throughout its lifecycle, from collection to analysis, is crucial for maintaining trust in the system’s outputs [15].
