TopIntroduction
It is impossible to exaggerate the critical necessity of cybersecurity in the fast changing digital environment of the twenty-first century. Fortifying digital environments against harmful actions has become a necessity due to expanding interconnectedness, technological advancement, and cyberthreat sophistication (Cybersecurity, 2018). Systems for surveillance, which act as watchful defenders in this digital world, have become crucial elements of all-encompassing cybersecurity plans.
In-depth analysis of the complex environment of surveillance systems created specifically to support cybersecurity measures is provided in this review paper. These defense-leading technologies offer a holistic security approach that includes continuous monitoring in real time, early threat identification, and quick incident response (Mekala & Vennila, 2018). They are important because they can spot, evaluate, and stop cyber threats before they become full-fledged breaches, which is essential for maintaining the integrity of digital records and defending the virtual spaces on which we are becoming more and more reliant.
An important place to start is how surveillance systems are categorized. There are three main varieties of these systems, each with a distinct emphasis and range. Utilizing advanced tools like intrusion detection and prevention systems (IDS and IPS), network surveillance involves the ongoing monitoring along with analysis of network traffic. These systems carefully examine data packets as they go via networks, compared them to known signatures of attacks or behavioral norms. Alerts are set off or automated responses are performed to neutralize possible dangers when deviations from the usual are found. Endpoint surveillance, on the other hand, focuses on specific networked devices. Computers, servers, and Internet of Things (IoT) gadgets are among these items, and they act as the first line of defense against online attacks. These devices' activities are tracked and analyzed by endpoint detection and response, or EDR, systems, which give cybersecurity personnel immediate knowledge of potential intrusions. Due to the ability to quickly respond to threats, hostile actions can be contained and stopped before they have a chance to do serious harm. The third sort of technology, behavioral surveillance, ushers machine learning and artificial intelligence into the field of cybersecurity (Drewek-Ossowicka et al., 2021). For consumers, devices, and networks, these systems provide baselines of typical behavior that allow them to identify variations that could be signs of unauthorized activity. For instance, User and Entity Behavior Analytics (UEBA) systems make use of advanced analytics to spot anomalies and new dangers, empowering cybersecurity teams to proactively handle internal and external security breaches.
Data gathering, analysis, and response are the three main building blocks of surveillance systems. In the data collecting phase, information is gathered from a variety of sources, such as network activity, log files, as well as user activity. In order to find trends, abnormalities, and potential risks, this data is then put into analytical pipelines that make use of cutting-edge machine learning algorithms. Automated measures can be triggered in response to suspicious activity, from isolating infected devices to notifying cybersecurity experts for human intervention. The variety of uses that surveillance systems have within the cybersecurity field demonstrate their adaptability. These systems stand out in the field of threat detection (Asif et al., 2021). Surveillance systems may quickly identify both known and unidentified risks by evaluating real-time data and compared it to predetermined baselines, enabling prompt countermeasures to be taken. These systems are also essential resources for incident response. Rapid and focused measures are necessary after a cyberattack to reduce damage. Systems for surveillance provide the tools needed to evaluate the severity and impact of an occurrence, allowing for efficient containment and mitigation measures.
Key Terms in this Chapter
Behavioral Analytics: Behavioral analytics is a method of identifying security threats by analyzing deviations from normal user, device, or network behavior, often using machine learning and statistical techniques.
Cultural Acceptance: Cultural acceptance refers to the development of a corporate culture within an organization that fosters security awareness and trust among employees regarding the use of surveillance systems for cybersecurity.
Zero Trust Architecture: Zero Trust Architecture is a security model that operates on the principle of verifying every user and device trying to access resources within an organization's network, even if they are already inside the network.
Cloud-Based Surveillance: Cloud-based surveillance involves using cloud computing infrastructure and services for the storage and analysis of surveillance data, offering scalability and accessibility advantages.
Vulnerability Management: Vulnerability management is the systematic process of identifying, assessing, and mitigating potential security vulnerabilities in an organization's digital infrastructure to reduce the risk of exploitation.
Adaptive Threats: Adaptive threats are cyber attackers who continuously adapt their tactics and methods to evade detection and compromise digital systems effectively.
False Positives: False positives occur when surveillance systems generate alerts or warnings for behaviors or events that do not actually pose a security threat, potentially causing unnecessary concern or distraction.
Privacy-Enhancing Technologies: Privacy-enhancing technologies are tools and methods designed to safeguard individual privacy while allowing for the collection and analysis of data for security purposes.
Surveillance Systems: Surveillance systems are integrated technologies and processes that continuously monitor digital environments to identify, analyze, and respond to cyber threats and security incidents effectively.
Incident Response: Incident response is a structured approach used to manage and mitigate cybersecurity incidents, including security breaches and cyberattacks, to minimize their impact on an organization.
