In 1991, U.S. Federal Sentencing Guidelines were developed to provide judges with courses of action in dealing with white collar crimes. These guidelines provided ways that companies and law enforcement should prevent, detect and report computer crimes. It also outlined how senior management are responsible for the computer and information security decisions that they make and what actually took place within their organizations.

Network bandwidth is the least important consideration when considering transmission security, as it is more related to the performance or efficiency of the network, rather than the security or protection of the data. Network bandwidth is the amount of data that can be transmitted or received over a network in a given time period, and it can affect the speed or quality of the communication1. However, network bandwidth does not directly impact the confidentiality, integrity, or availability of the data, which are the main goals of transmission security. Network availability, data integrity, and node locations are more important considerations when considering transmission security, as they can affect the ability to access, verify, or protect the data from unauthorized or malicious parties.

"It [ACL] specifies a list of users [subjects] who are allowed access to each object" CBK, p. 188
A capability table is incorrect. "Capability tables are used to track, manage and apply controls based on the object and rights, or capabilities of a subject. For example, a table identifies the object, specifies access rights allowed for a subject, and permits access based on the user's posession of a capability (or ticket) for the object." CBK, pp. 191-192
The distinction that makes this an incorrect choice is that access is based on posession of a capability by the subject.
To put it another way, as noted in AIO3 on p. 169, "A capabiltiy table is different from an
ACL because the subject is bound to the capability table, whereas the object is bound to the ACL."
An access control matrix is incorrect. The access control matrix is a way of describing the rules for an access control strategy. The matrix lists the users, groups and roles down the left side and the resources and functions across the top. The cells of the matrix can either indicate that access is allowed or indicate the type of access. CBK pp 317 - 318
AIO3, p. 169 describes it as a table if subjects and objects specifying the access rights a certain subject possesses pertaining to specific objects.
In either case, the matrix is a way of analyzing the access control needed by a population of subjects to a population of objects. This access control can be applied using rules,
ACL's, capability tables, etc.
A role-based matrix is incorrect. Again, a matrix of roles vs objects could be used as a tool for thinking about the access control to be applied to a set of objects. The results of the analysis could then be implemented using RBAC.

Transport Layer Security (TLS) is the protocol that is primarily adopted for ensuring the integrity of information is preserved. Integrity is the property that ensures that the information is not modified, corrupted, or destroyed by unauthorized or accidental means, and that it remains consistent and accurate throughout its lifecycle. TLS is a protocol that provides security and privacy for the communication and the exchange of information over the internet, such as the web, the email, the instant messaging, or the voice over IP. TLS operates at the transport layer of the network model, and it uses encryption, authentication, and integrity mechanisms to protect the data and the messages that are transmitted between the parties. TLS is primarily adopted for ensuring the integrity of information is preserved, as it uses various techniques and algorithms to verify and confirm that the data and the messages have not been altered, tampered, or compromised during the transmission. Some of the techniques and algorithms that TLS uses for ensuring the integrity of information are:
* Hashing: TLS uses hashing functions, such as SHA-256 or SHA-384, to generate a fixed-length and unique value, called a hash or a digest, for the data or the message. The hash is then appended to the data or the message, and sent along with it. The receiver can then compute the hash of the received data or message, and compare it with the hash that was sent. If the hashes match, it means that the data or the message has not been modified or corrupted. If the hashes do not match, it means that the data or the message has been altered or tampered.
* Message Authentication Code (MAC): TLS uses MAC algorithms, such as HMAC-SHA256 or HMAC-SHA384, to generate a code or a tag, called a MAC, for the data or the message, using a secret key that is shared and agreed upon by both parties. The MAC is then appended to the data or the message, and sent along with it. The receiver can then compute the MAC of the received data or message, using the same secret key, and compare it with the MAC that was sent. If the MACs match, it means that the data or the message has not been modified or corrupted, and that it came from the legitimate and trusted source. If the MACs do not match, it means that the data or the message has been altered, tampered, or spoofed.
* Digital Signature: TLS uses digital signature algorithms, such as RSA or ECDSA, to generate a signature or a value, called a digital signature, for the data or the message, using the private key of the sender. The digital signature is then appended to the data or the message, and sent along with it. The receiver can then verify the digital signature of the received data or message, using the public key of the sender. If the digital signature is valid, it means that the data or the message has not been modified or corrupted, and that it came from the legitimate and trusted source. If the digital signature is invalid, it means that the data or the message has been altered, tampered, or spoofed.
Therefore, TLS is the protocol that is primarily adopted for ensuring the integrity of information is preserved, as it uses hashing, MAC, and digital signature techniques and algorithms to verify and confirm that the data and the messages have not been modified, corrupted, or compromised during the transmission.
