As the COVID-19 pandemic scattered businesses and their workforces into new scales of remote work, vital security concerns arose surrounding remote access. Bring Your Own Device (BYOD) also plays a growing role in the ability of companies to support remote workforces. As more enterprises embrace concepts of zero trust in their network security posture, access control policy management problems become a more significant concern as it relates to BYOD security enforcement. This BYOD security policy must enable work from home, but enterprises have a vested interest in maintaining the security of their assets. Therefore, the BYOD security policy must strike a balance between access, security, and privacy, given the personal device use. This paper explores the challenges and opportunities of enabling zero trust in BYOD use cases. We present a BYOD policy specification to enable the zero trust access control known as BYOZ. Accompanying this policy specification, we have designed a network architecture to support enterprise zero trust BYOD use cases through the novel incorporation of continuous authentication & authorization enforcement. We evaluate our architecture through a demo implementation of BYOZ and demonstrate how it can meet the needs of existing enterprise networks using BYOD.

The competency to use mobile devices for work-related tasks gives advantages to the company productiveness and expedites business processes. Thus Bring Your Own Device (BYOD) setting emerge to enable work flexibility and technological compatibility. For management, employees’ productivity is important, but they could not jeopardise the security of information and data stored in the corporate network. Securing data and network becomes more complex tasks as it deals with foreign devices, i.e., devices that do not belong to the organisation. With much research focused on pre-implementation and the technical aspects of mobile device usage, post-implementation advancement is receiving less attention. IS audit as one of the post-implementation mechanisms provides performance evaluation of existing IS assets, business operations and process implementation, thus helping management formulating the best strategies in optimising IS practices. This paper discusses the feasibility of IS audit in assessing mobile device security by exploring the risks and vulnerabilities of mobile devices for organisational IS security as well as the perception of Information system management in mobile device security. By analysing related literature, authors pointed out how the references used in the current IS audit research address the mobile device security. This work serves a significant foundation in the future development in mobile device audit.

BYOD or Bring Your Own Device is a set of policies that allow employees of an organization to use their own devices for official work purposes. BYOD is an immensely popular concept in the present day due to the many advantages it provides. However, the implementation of BYOD policies entail diverse problems and as a result, the confidentiality of documents can be breached. Furthermore, employees without security awareness and training are highly vulnerable to endpoint attacks, network attacks, and zero-day attacks that lead to a breach of confidentiality, integrity, and availability (CIA). In this context, this paper proposes a comprehensive solution; ‘BYODENCE’, for the detection and prevention of unauthorized access to organizational documents. BYODENCE is an efficient BYOD solution which can produce competitive results in terms of accuracy and speed.

The Security available in personal computers and laptops are not possible in mobile communication, since there is no controlling software such as an operating system. The European Union General Data Protection Regulation (GDPR) will require many organisations throughout the European Union to comply with new requirements that are intended to protect their user's personal data. The responsibilities of the organizations and the penalties related to the protection of personal data of the users are proved to be both organisationally and technically challenging. Under the GDPR's 'privacy by design' and 'privacy by default' requirements, organizations need to prove that they are in control of user data and have taken steps to protect it. There are a large number of organizations that makes use of mobile devices to process personal data of their customers. GDPR mandates that the organization shall be able to manage all devices that handles sensitive data so that the company can implement group updates, restrict apps and networks, and enforce security measures. In this work, we propose a Mobile Device Management solution using the built-in frameworks of Android and iOS mobile platforms which is compatible and incorporates GDPR articles relevant to a small to medium sized organization.

Bring Your Own Device (BYOD) is a new trend where employees use their personal devices to connect to their organization networks to access sensitive information and work-related systems. One of the primary challenges in BYOD is to securely delete company data when an employee leaves an organization. In common BYOD programs, the personal device in use is completely wiped out. This may lead to the deletion of personal data during exit procedures. Due to performance and deletion latency, erasure of data in most file systems today results in unlinking the file location and marking data blocks as unused. This may suffice the need of a normal user trying to delete unwanted files but the file content is not erased from the data blocks and can be retrieved with the help of various data recovery and forensic tools. In this paper, we discuss: (1) existing work related to secure deletion, and (2) secure and selective deletion methods that delete only the required files or directories without tampering personal data. We present two per-file deletion methods: Overwriting data and Encryption based deletion which erase specific files securely. Our proposed per-file deletion methods reduce latency and performance overheads caused by overwriting an entire disk.

BYOD (Bring Your Own Device) trends allows employees to use the smartphone as a tool in everyday work and also as an attendance device. The security of employee attendance system is important to ensure that employees do not commit fraud in recording attendance and when monitoring activities at working hours. In this paper, we propose a combination of fingerprint, secure android ID, and GPS as authentication factors, also addition of anti emulator and anti fake location module turn Mobile Attendance System into Mobile Secure Attendance System. Testing based on scenarios that have been adapted to various possible frauds is done to prove whether the system can minimize the occurrence of fraud in attendance recording and monitoring of employee activities.

The recent proliferation of the Internet of Things (IoT) technology poses major security and privacy concerns. Specifically, the use of personal IoT devices, such as tablets, smartphones, and even smartwatches, as part of the Bring Your Own Device (BYOD) trend, may result in severe network security breaches in enterprise environments. Such devices increase the attack surface by weakening the digital perimeter of the enterprise network and opening new points of entry for malicious activities. In this paper we demonstrate a novel attack scenario in an enterprise environment by exploiting the smartwatch device of an innocent employee. Using a malicious application running on a suitable smartwatch, the device imitates a real Wi-Fi direct printer service in the network. Using this attack scenario, we illustrate how an advanced attacker located outside of the organization can leak/steal sensitive information from the organization by utilizing the compromised smartwatch as a means of attack. An attack mitigation process and countermeasures are suggested in order to limit the capability of the remote attacker to execute the attack on the network, thus minimizing the data leakage by the smartwatch.

The continued acceptance of enhanced security technologies in the private sector, such as two-factor authentication, has prompted significant changes of organizational security practices. While past work has focused on understanding how users in consumer settings react to enhanced security measures for banking, email, and more, little work has been done to explore how these technological transitions and applications occur within organizational settings. Moreover, while many corporations have invested significantly to secure their networks for the sake of protecting valuable intellectual property, academic institutions, which also create troves of intellectual property, have fallen behind in this endeavor. In this paper, we detail a transition from a token-based, two-factor authentication system within an academic institution to an entirely digital system utilizing employee-owned mobile devices. To accomplish this, we first conducted discussions with staff from the Information Security Office to understand the administrative perspective of the transition. Second, our key contribution is the analysis of an in-depth survey to explore the perceived benefits and usability of the novel technological requirements from the employee perspective. In particular, we investigate the implications of the new authentication system based on employee acceptance or opposition to the mandated technological transition, with a specific focus on the utilization of personal devices for workplace authentication.

Kings Eye is a platform independent situational awareness prototype for smart devices. Platform independence is important as there are more and more soldiers bringing their own devices, with different operating systems, into the field. The concept of Bring Your Own Device (BYOD) is a low-cost approach to equipping soldiers with situational awareness tools and by this it is important to facilitate and evaluate such solutions.

The trend towards Cloud computing infrastructure has increased the need for new methods that allow data owners to share their data with others securely taking into account the needs of multiple stakeholders. The data owner should be able to share confidential data while delegating much of the burden of access control management to the Cloud and trusted enterprises. The lack of such methods to enhance privacy and security may hinder the growth of cloud computing. In particular, there is a growing need to better manage security keys of data shared in the Cloud. BYOD provides a first step to enabling secure and efficient key management, however, the data owner cannot guarantee that the data consumers device itself is secure. Furthermore, in current methods the data owner cannot revoke a particular data consumer or group efficiently. In this paper, we address these issues by incorporating a hardware-based Trusted Platform Module (TPM) mechanism called the Trusted Extension Device (TED) together with our security model and protocol to allow stronger privacy of data compared to software-based security protocols. We demonstrate the concept of using TED for stronger protection and management of cryptographic keys and how our secure data sharing protocol will allow a data owner (e.g, author) to securely store data via untrusted Cloud services. Our work prevents keys to be stolen by outsiders and/or dishonest authorised consumers, thus making it particularly attractive to be implemented in a real-world scenario.
