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.

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].

It is possible to determine the acts that led to the current condition of computer security. Explain.
Let us consider an application where we need to run a secure Information Management System. We are to receive very confidential information from our customer sand keep them save in our system. These information are sent to us in the softcopy forms. We are to protect ourcustomers’ confidentiality even from ourselves, we are not to see the information they bring to us,or else the confidentiality is compromised. Your job as computer security officer is to verify the authenticity of the important documentreceived in order to save them under the appropriate users. Mind you; you have no access to the users’ usernames and passwords, you can storebut cannot retrieve except the user himself. Secondly, you are to protect the passwords and usernames to make impossible for everyone(including the system administrators) except the users themselves to access even if the whole data base is hacked or stolen. i)Based on your knowledge in computer security, which cryptographic mechanisms would you…

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), •
Question 10 Determine the minimum required length for a password to have at least 128 bits of entropy. The password is alphanumeric and case-sensitive. Show your calculation steps and provide an explanation of how you arrived at the answer. Why is the entropy an approximation and not a true reflection of the strength of a password?
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…
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?
Can you Define in 1500 words, the access control as well as the means and components of security.?
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
