In this article, we present a collaborative resource allocation technique using the Market Game that utilizes the Shapley value solution concept which is a method used in the field of Political- Economy for fair distribution of resources as exemplified in a welfare state. Modelled on the Long Term Evolution (LTE) Advanced Network, the results show an improvement in the throughputs achieved by users of the network.

However, CI driven by ICT is inherently vulnerable to cyberattacks with potentials for cascaded and escalating effects on depending and interconnected CIs. Therefore, the degree of CI dependency on ICT is a cyber risk factor that requires empirical quantification. Consequently, an ICT Dependency Model was developed for this purpose, based on predefined pillars, namely: Adoption, Integration and Automation. These pillars form the basis for computation of the ICT dependency index (IDI). The ICT Dependency Quadrant (IDQ) is introduced to categorise the IDI of CI organisations into four quadrants, viz: Q1, Q2, Q3 and Q4. Twenty-seven CI organisations participated in the pilot test of the model. The Findings showed that 3 of the CI organisations fall in Q4, while 20 fall in Q3. Similarly, 3 and 1 organisations fall into Q2 and Q1 respectively. The combination of IDI and IDQ provide a comparative tool to visualise the various IDI scores in a single view. Thus, it supports the monitoring of the growth of ICT in CI organisations vis-à-vis the potential cyber risk it presents.

Kulugh, Victor Emmanuel Critical infrastructures (CI) at the national or organizational level is nowadays seen as both inclusive of and dependent on the Information Communications Technology (ICT) infrastructure for interconnecting and driving other infrastructures for sustained productivity, efficiency and growth. The interconnections that ICT facilitate through global and national networks however also make CI and Critical National Information Infrastructure (CNII) highly susceptible to malicious cyber-attacks sponsored by rival or antagonistic actors. Hence, nations must design and deploy strategic plans for CNII protection against such attacks. In Nigeria, the 2015 Cybercrimes (Prohibition and Prevention) Act empowers the President to designate and protect certain assets or services as CNII. However, there is currently no scientific framework or criteria in the country for determining which information assets, services and functions qualify as CNII. This paper presents a framework for identifying, characterizing and properly designating CNII in Nigeria based on descriptive, analytical and design research processes. The methodology entailed analysis and synthesis of concepts and ideas relating to CNII definitions, design, protection and management proposed or deployed for other countries. The outcome is a robust framework that defines logical steps for the identification, assessment and proper designation of CNI for Nigeria and possibly other developing countries. The research steps involved the characterization of CI, determination of CI dependencies on ICT, and measurement of the criticality of such dependencies. Planned future work would within the framework would then focus on the design and development of mathematical and computational constructs, algorithms to create automated tools for the computation, visualisation and comparison of the criticality metrics different components of CNII.

Notably, there is no globally acceptable criteria for the designation of an infrastructure as Critical National Infrastructure (CNI) or CNII. However, there is a consensus that CNIs are vital for a modern society, and drives economic growths and national prosperity. Although there are similarities in such infrastructures worldwide, every nation determines the value to attach to each CNI depending on its developmental goal, priorities and the level of dependency on such infrastructure. In Nigeria, there is no publicly available information on the categorisation of infrastructures as CNI or CNII. The mythological approach adopted was document scan, analysis and synthesis of publicly available information on CNI and CNII of some selected countries, followed by a comparative analysis. Five countries were selected from each of the six continents based on population size and adoption of Information and Communications Technology (ICT). The findings revealed that about 90% of the countries studied categorised energy, transportation, water, communications and health as sectors of CNI. Conceptually, based on the outcome, CNIs in Nigeria were characterised into twelve critical sectors. This initial study forms the first step towards development of a framework for the correct designation of an infrastructure as a CNII in Nigeria as opposed to arbitrary designation.
