The state in which Mark encrypted the data in the above scenario is data in use. Data in use refers to data that is being processed or manipulated by an application or a system, such as data stored on RAM or CPU registers. Data in use is the most vulnerable state of data, as it is exposed to various threats, such as memory scraping, buffer overflow, or side-channel attacks, that can compromise the confidentiality, integrity, or availability of the data. Data in use encryption is a technique that protects the data while it is being processed by encrypting it in memory using hardware or software solutions. Data in use encryption prevents unauthorized access or modification of the data, even if the system is compromised or the memory is dumped.Data in use encryption is one of the three types of data encryption, along with data at rest encryption and data in transit encryption123.References:

Physical security controls are security measures that prevent or deter unauthorized physical access to a facility, resource, or information. Physical security controls include locks, doors, gates, fences, guards, cameras, alarms, sensors, biometrics, and badges. Physical security controls protect the network and its components from theft, damage, sabotage, or natural disasters. Clark implemented physical security controls in the above scenario, as he installed security controls that allow employees to enter the office only after scanning their badges or fingerprints.References:

Atomic-signature-based analysis is a type of attack signature analysis technique that uses a single characteristic or attribute of a packet header to identify malicious traffic. Atomic signatures are simple and fast to match, but they can also generate false positives or miss some attacks. Some examples of atomic signatures are source and destination IP addresses, port numbers, protocol types, and TCP flags. Atomic-signature-based analysis is the technique performed by Joseph in the above scenario, as he analyzed packet headers to check whether any indications of source and destination IP addresses and port numbers are being changed during transmission.References:
