MSc Information Security research project: Overview of the methods and materials

It is difficult to ensure effectiveness of information security programme in the company without paying attention to users’ behaviour. One of the challenges for the security manager, when implementing information security policy, is to differentiate between malicious non-compliance and non-compliance due to the obstruction of business activities.

The main goal of this project is to gain an insight into information security behavior issues, from both an end-users’ and security managers’ perspectives. The study aims to develop a model to support security managers’ decision-making process when implementing security policy in the organisation. It is important to help security managers make a user a part of the system and to go beyond formal box-ticking when ensuring compliance with legal and regulatory requirements.

In order to achieve the objectives of the study, a method consisting of three parts was followed, including presenting example scenario and development of the model to address the research question for the first part, a survey and interviews for the second part, and interviews for the third part.

Stage one: Develop a model

The objective of the first stage is to motivate the research problem, presenting example scenario of poorly implemented security policy in the fictitious company, and to develop a model to support security manager’s decision-making process in implementing security controls in a company.

The example scenario presents the hypothesis that users’ experience and role of the manager are mismatched. Manager may think that user’s effort is unlimited. At the moment there is no way of directly comparing users’ and security manager’s perception of behavioural impact of security policy in the organisations.

The model is developed to support security managers’ decision-making process when implementing security policy in a company and to provide a tool of assessing users’ workload with security tasks.

The following stage shows that described mismatch exists and the developed model deals with the outlined problem.

Stage two Comparing views on security compliance behaviour in an organisation

The aim of the second part is to gather real-world data to highlight the importance of security compliance behavior and identify relevant problems which can arise when a security manager chooses a particular way of implementing information security controls in the organization. Moreover, this part aims to compare views of security managers and users on the problem of compliance behaviour.

For the purpose of this stage a combination of qualitative and quantitative methods was used.

As a part of the quantitative method, semi-structured interviews with five information security experts were conducted. In parallel 64 users were surveyed using an online surveying platform. For the purpose of the survey, eleven multiple-choice questions were developed, in collaboration with an academic with experience in this field.

Stage three: Validation of the developed model

The goal of the third stage of the study was to validate the model and gather relevant feedback from information security experts.

Five semi-structured interviews were conducted with information security experts.

Invitations for an interview were also distributed to outline the approximate duration of the interview, intended questions, to give insight on the procedure and to provide high-level information on the study.

Written consents were collected from the interviewees prior to the interview.

Interviews with security experts consisted of two parts:

  1. General questions on the security manager’s decision-making process regarding the implementation of security controls when ensuring compliance within the company (Stage two).
  2. Validating the model to support the security manager’s decision-making process (Stage three).

Pilot interviews were first carried out. Feedback gathered from the pilot interviews was used to improve model presentation technique, modify existing questions, and add new questions. Materials from the pilot interviews were not included in the thesis.

Each interview took approximately 50 minutes. All interviews were conducted face-to-face and at participants’ offices at a time convenient for them.

In the second part of the interview the same experts were presented the model after they had answered the question around validation of the importance of compliance behaviour. The study aims to assess how the presented model changed their decision-making process when thinking in terms of making users an essential part of the system.

Audio recordings were subsequently used by the researcher to develop interview transcripts, parts of which are presented in this work to support various points and provide insight on relevant issues.

MSc Information Security thesis abstract

speak

Security managers in companies lack a clear process to implement security controls in order to ensure compliance with various regulations and standards.

Interviews with experts show that security managers may take ISO 27001 standard as a framework and then make a decision on any particular implementation based on their experience.

Such implementations run the risk of creating collisions with users’ business activities and result in violation of security policies in the company, because they introduce friction with the business process. Users try to avoid such friction. It is important, however, to differentiate between malicious non-compliance and cases when security policy obstructs business processes leading to workarounds.

This piece of research presents example scenarios of such clashes and explores the root causes of events of non-compliance.

A model is developed that supports security managers’ decision-making process and incorporates users into the system in a way that mitigates the negative impact on users’ behaviour of security policy.

A combination of quantitative and qualitative methods is applied to research the perception of information security by both users and security managers: the survey was created and 64 participants were surveyed to gain an insight into users’ perspective of implemented information security controls; semi-structured interviews with five experts were conducted, who have seven or more years of experience in the information security field and currently hold managerial positions.

The study illustrates that company can be formally compliant but still inefficient in performing its revenue-generating activities. Moreover, there is a mismatch between users’ and security managers’ perception: security managers think that they are already paying attention to the users, but 23% users complain that security activities negatively affect their performance.

The presented model is validated by information security experts and provides clear guidance to security managers in organisations as to implementation of security controls. The majority of experts liked the approach, but said that it needs to be tried with real-world processes.

Modelling conflicts between information security compliance and behaviour

With this post I’m starting a series of articles on information security compliance and behaviour issues.

It is important for security managers to understand that their decisions affect the company as a whole.  However, there are instances when business activities and security tasks are not synchronised. For example, the New York Times website was unavailable for several hours on the 14th of August 2013. While a malicious attack was initially suspected, the problem was caused simply by scheduled system maintenance procedure.
On the one hand, violation of compliance requirements may result in significant losses for an organisation. On the other hand, poorly implemented security policies may obstruct users’ goal-driven behaviour and may result in non-compliance.

Security managers and users may share different views on security activities. In order to ensure that users in the organisation will comply with security policies, the security manager should broaden his perspective and make users a part of the system.

Lack of clear guidance in this decision-making process may result in the situation in which a company is formally compliant with the standard but users perform their core business activities inefficiently and/or are forced to violate poorly implemented security policies.
