The best practice when handling and investigating digital evidence for use in a criminal cybercrime investigation is to ensure that digital devices are forensically ''clean'' before any investigation takes place. This means that the devices should be free from any potential contamination that could compromise the integrity of the evidence. It's crucial to maintain the original state of digital evidence as much as possible to ensure its admissibility in court. Altering digital evidence should be avoided unless it's absolutely necessary for the investigation, and even then, it should be done following strict protocols to document the changes made. While law enforcement often handles digital evidence, the principle of maintaining a forensically clean state applies universally to ensure the evidence remains untainted and reliable.

Access controls are essential in information security for ensuring that resources are available to authorized users and protected from unauthorized access. The methods of access control can be categorized as follows:

Detective: These controls are designed to identify and record unauthorized access attempts. They do not prevent access but are useful for auditing and monitoring purposes.

Physical: Physical controls are tangible measures taken to protect assets, such as locks, fences, and security guards.

Preventive: Preventive controls are designed to stop unauthorized access before it happens. This includes mechanisms like passwords, biometric scans, and encryption.

The combination of detective, physical, and preventive controls provides a robust framework for managing access to sensitive information and systems. Reactive controls are not typically classified as access controls since they deal with responding to incidents after they occur, and virtual controls are not a recognized category in this context.

The term ''Break Glass'' refers to an emergency access procedure that allows users to bypass normal security controls to gain access to a system or service during a critical situation. This method is analogous to breaking the glass of a fire alarm to handle an emergency. In the context of information security management, it is a controlled process that is typically documented, monitored, and audited to ensure it is used only during genuine emergencies.It is a part of an organization's disaster recovery and business continuity planning, ensuring that critical systems can still be accessed when standard authentication methods fail or are unavailable due to various reasons such as service outages, DDoS attacks, or loss of access by the primary administrator12.

The primary security concern with BYOD is the reduced level of control an organization has over employees' personal devices compared to corporately owned and managed devices. This lack of control can lead to inconsistent security practices, such as irregular updates, lack of standardized security software, and potential for data leakage if the device is lost or compromised.BYOD policies must address these challenges by implementing security measures that protect corporate data while respecting users' privacy on their personal devices123.

The BCS Foundation Certificate in Information Security Management Principles outlines the importance of managing information risk and implementing comprehensive security controls, which are particularly relevant for BYOD policies1.

Literature on BYOD security risks and mitigation strategies provides insights into the challenges and best practices for managing personal devices in a corporate environment2.

Reviews of security access control policies and techniques based on privacy requirements in a BYOD environment offer a systematic approach to addressing BYOD security concerns3.

An Information Owner is typically responsible for determining the classification of the information and for ensuring that it is handled and protected in accordance with its classification. This includes the right to assign access privileges to others, which allows the Information Owner to control who can access the information and what level of access they have. This right is essential for maintaining the confidentiality, integrity, and availability of the information, which are core principles of information security management.The Information Owner's role is to ensure that only authorized individuals have access to the information and that they have the appropriate level of access based on their role and need to know.Reference: BCS Foundation Certificate in Information Security Management Principles1.
