Results
Critical analysis

Cyber resilience refers to an emerging security paradigm that promotes a vigorous and dynamic approach to securing organizational information. Within the evolving landscape of cybersecurity, organizations are required to incorporate more resilient and persistent cyber strategies to deal with cyber threats. The cyber resilience techniques rely on the five key pillars including identity, protection, threat detection, response and recovery [8].

The cyber-resilient infrastructure is safeguarded against cyber threats and ensures continuous operation. This further assists in the minimisation of the risks and service disruption.

Findings and Discussion

Theme 1: key cyber threats to the cloud-based critical infrastructure

The cloud-based critical infrastructure poses several issues in the existing cyber security systems. One of the most crucial issues in cyber security for critical infrastructure is the widespread utilisation of the legacy system [9]. The traditional systems are inadequate to prevent cyber threats resulting in issues in identifying and targeting the cyber criminals. Insider threats are the emerging risks for critical infrastructure in case of both accidental and international threats. Ransomware attacks are a commonly spread incident with 214 incidents in the first quarter of 2023 which increase of 13 per cent from the previous quarter [10]. In case of the financial technology-based companies, the increasing emergence of advanced persistent threats steals the data and maintains extended access to the cyber security systems. The distributed denial of services attacks the critical infrastructure systems with traffic which causes significant disruption in various areas, especially financial and technology-based sectors. Artificial intelligence expedites these cyber-attacks by reducing the average speed of the DDoS from 184 seconds in 2021 to only 55 seconds in 2022.

Theme 2: Existing cyber resilience strategies within the cloud- based infrastructure

The cyber resilience strategies aligned with the organizational objectives through the identification of the current information, services and systems which are essential for the organizations. The holistic cyber resilience strategy includes cybersecurity at all levels to safeguard the organizations through detecting threats and recovering from the issues. The cyber resilience strategy includes cybersecurity systems that assist in the protection of systems, data and applications [11]. Preventing the hostile issues through the identification of potential vulnerabilities is necessary for securing cloud infrastructures from the sticking effects. It includes the endpoint detection and responses along with the extended detection and responses. Despite the vigorous cybersecurity measures, the risk of cyber-based incidents poses significant issues which have to be maintained through proposing business continuity and resilience programmes. In the case of the efficiency process and technology, the initiatives regarding cyber resilience and string governance become paramount for the organizations. It assists substantially in the maintenance of people’s activity, process and actionable solutions for providing guidance to cyber resilience.

Theme 3: potential improvement opportunities within the current practices

In order to keep the organization cyber-safe, the organizations have to focus on some key techniques. It is essential for organisations to determine the possible events of a cyber incident, through the identification of the essential information, the cyber security techniques expand the baseline for the cyber-resilience strategy.

Figure 2: Cyber Security Reference Model [13]

The technological aspects are not enough for the elimination of cyber vulnerabilities. The significant integration of cyber- resilience mechanisms through ensuring the skills of the employees contributes significantly in the protection drawing any security incident. Organizations should increase the investment level in the stimulation of “Security Information and Event Management” is crucial for maintaining the scalability and consistency within the cloud-based critical infrastructure.
