Unfortunately,the value of the assets that could be compromised through an IT system extends beyond the monetaryvalue: it is impossible to ignore that the security of IT often affects the safety of OperationalTechnologies (OT). IT systems suffer from failures in maintaining security because of their increasingcomplexity, the evolution of attackers’ capabilities, and the increasing value of the assets that theyhold. Exploitable vulnerabilities and risks will always exist, and their characteristics can change overthe course of an IT system’s life. There is, however, a need to manage within acceptable parametersthese errors, vulnerabilities and risks over the life of IT system. The task of those responsible for thesecurity of IT systems is to establish acceptable levels of security assurance and risk objectives for theIT system.In terms of IT security, adequate security assurance signifies that specific predefined securityrequirements have been addressed through the presentation of a security assurance case: it is theresult of performing appropriate security assurance processes and activities. These security assuranceprocesses and activities need to be described in the form of a reasoned and compelling argument (ormany arguments), supported by a body of evidence for a security-related claim. Such a claim istypically about certain Security Targets being met by product, system, service or organisation.Security assurance requirements are determined from the security problem posed by the deliverable(and potentially other factors), influencers, security requirements, and the target environment for thedeliverable. As such, it is important to understand and specify the scope and boundaries for adeliverable that is subject to a security assessment.Security assurance arguments substantiate security assurance claims which means that the argumentsshould be structured in the appropriate manner. In general, security assurance arguments can beconstructed in many different ways and drawn from many different sources. However, for thisassessment Target of Evaluation (TOE) is a product or service. Security assurance argument must bebased on one of the following alternatives:(a) Tools/methods used to test and evaluate TOE;(b) Tools/methods used to design TOE.In order to score a higher grade for their essay, students must follow specific pattern: the essay shouldcontain the main security argument, counterargument and defence of the main security argument.The scope of security problems for your essay is bounded by those occurring in authentication andaccess control systems. In the essay, a student is encouraged to develop an assurance argument thatcontributes to one of the following security requirements:– Human user identification and authentication;– Machine (e.g. IoT) identification and authentication;– Account management;– Authenticator management;– Strength of password-based authentication;– Strength of public key authentication;– Authorization enforcement;– Auditable events;– Non-repudiation.It is not required to develop a complete security assurance case for one of the listed requirements.For the essay, it is sufficient to evolve around argument(s) that can fit within potential assurance case.For instance, an argument that claims security/privacy of attribute-based authentication may fitwithin the assurance cases for ‘Human user identification and authentication’, ‘Machine (e.g. IoT)identification and authentication’, ‘Authorization enforcement’. However, it is the student’s task todemonstrate ‘how?’ security assurance argument fits there. The length of the essay should be 1500-2000 words (minimum 1500 words, single spaced, 12pt font, on the A4-sized paper).Marking Criteria for Assessment 1Criterion Rating scale Criterionscore1.
