In the context of information security, the principle of 'need-to-know' isone of the most important ones to consider. What does the principle of'need-to-know' implies? *Critical tasks can only be completed by at least two individuals, so that collusion isneeded to be able to commit fraud.Users should have access to only the information that is needed to perform theirtasks.Users should be assigned with a minimum level of access rights to perform theirtasks.O Users should be assigned only temporary access rights to perform their tasks.

Paul needs to read and write some documents. In the following, assume the system security policy is described completely by the Bell-LaPadula model. Note that the situation described may be impossible, in which case say so and show why. Please give the least clearance that Paul can have if he wishes to read a document with classification (SECRET, {NUC, EUR}) and a document with classification (CONFIDENTIAL, {ASI}). Please give the greatest clearance that Paul can have if he wishes to write to a document with classification (TOP SECRET, {EUR}) and a document with classification (SECRET, {EUR, NUC}). Please give the greatest clearance that Paul must have if he wishes to read a document with classification (SECRET, {EUR, NUC}), to write a document with classification (CONFIDENTIAL, {NUC, EUR}), and to read another document with classification (TOP SECRET, {ASIA, EUR}).
The following is a list of instances that illustrate how the confidentiality of data might be breached: After that, we will have a discussion about the many preventive actions that may be taken.
An ethical hacker makes multiple guesses at the admin password for a local school's web-server but is ultimately unsuccessful. Is this an offence, under the Computer Misuse Act (1990), and its later revisions? Yes, under section 2: Unauthorised Access with Intent Yes, under section 3A: Misuse of Tools Yes, under section 1: Unauthorised Access No, not technically Yes, under section 3ZA: Misuse of Tools for critical infrastructure
Construct a fake case concerning login management and describe it in detail. Determine alternative authentication procedures. The usage of a login and password is vital, but is it becoming obsolete?
A security policy is a document that provides employees with clear instructions about acceptable use of company confidential information, explains how the company secures data resources and what it expects of the people who work with this information. Most importantly, the policy is designed with enough flexibility to be amended when necessary. You are working in organization X, and you are supposed to develop an issue-specific security policy, you can pick one issue from Table.1 [1] (In the photos) Your Task is: To develop the different sections of your policy and adequate procedure(s), you can refer to SANS Policy Templates [2].

Take into consideration the various types of access control mentioned below, and choose some example scenarios. This is an example. • Discretionary Access Control (DAC), • Mandatory Access Control (MAC), • Role-Based Access Control (RBAC), • Attribute-Based Access Control (ABAC), • Rule-Based Access Control (RBAC), • Risk-Adaptive Access Control (RAC), • Identity-Based Access Control (IBAC), • Organization-Based Access Control (OBAC), •
c) You are in charge of designing a secure Internet Banking System. While designing the system, you need to consider several aspects of information security, such as: i) user authentication, ii) bank server authentication, iii) distribution of the public key (if using an asymmetric cipher), iv) distribution of the symmetric key (if using a symmetric cipher), v) confidentiality of the communication between the user and the bank server, vi) integrity of the communication between the user and the bank server, vii) non-repudiation. To address these design goals, you may need to use a combination of different types of cryptographic/security primitives. Symmetric Asymmetric Message authentication Digital encryption signatures exchange Hash Public key Key Digital Certificate Ciphers functions cades (MAC) Stream Block ciphers ciphers Figure 3: Basic cryptographic building blocks Select appropriate primitives that you propose to address each of the above security goals and provide necessary…
When attempting to convince someone of anything, it is helpful to provide instances. This section devotes a lot of attention to traditional personnel practises, as well as the controls and integration with information security principles that make it possible for such practises to play a part in the information security function.
One potential approach for safeguarding data through the application of the "Principle of Confidentiality" involves utilizing a "Cryptographic Technique." This technique can be employed to ensure that sensitive information remains secure and inaccessible to unauthorized parties.
One of the four methods of access control might be used in this scenario. What factors play a role in your decision-making process?
