The paper gives an overview of the threat models, STRIDE and PASTA. The threat modeling process involves optimization of the security connection by classifying the purposes and susceptibilities (Mc, 2013). The security measures are defined to control the threat effects in the system. The acronym STRIDE stands for spoofing, tampering, repudiation, information, denying and elevation. An example is a case where an individual hacks the username and passwords of other persons. Tampering involves the alteration of data stored in the database. On the other hand, repudiation refers to the situation where an individual transacts illegal transactions that cannot be ...

Nowadays cryptography is critical to all organizations. Cryptography is usually used by passwords, SSL, smart cards. Cryptographic systems can provide following services: 1) authentication, 2) non-repudiation 3) confidentiality 4) integrity. For user authentication the password should be used. The politics for password selection must be applied: the password should contain at least 8 symbols, have characters, symbols and numbers, so that it would be difficult to guess it. It is more secure to use two-factor authentication, rather relying entirely on password authentication. Non-repudiation tools are needed to prove that definite user made transaction (for example, queried statement). Only appropriate ...

Different techniques are used to protect the integrity of data as well as unauthorized access to such data using different techniques. Cryptography is one of the many techniques whereby plain text is changed to unreadable text with the aid of mathematical algorithms. One of these techniques is Public Key Infrastructure (PKI). A pair of keys is used in Public Key Cryptography to encrypt and decrypt information. Of these two keys, one is available publicly and can be known to anyone while the other is a private key and is only known to the owner of the key and used ...

Question 2.1 (50 points):

The forms of non-repudiation (non-repudiation of sender, non-repudiation of receipt and non-repudiation of actions) discussed in this week module are important to achieving information security since they offer a method through which the subject cannot deny performing a specific action. This is achieved through the assignment of a unique digital signatures to messages and actions that help in clearly identifying the sender, recipient, as well as, actions carried out. The forms of non-repudiation improve system security since they can help in tracing the sender and receiver. In the case of non-repudiation of sender, the sender of a message is ...

Business Law

The case is a promissory estoppel situation where Dhafir acted upon Hansen’s legal action if any damages occur from the falling tree. Hansen can place a claim stating the cutting of the diseased limb and not the whole tree as a premise. The courts will still proceed with the promissory that Hansen made as it is the ignitor of Dhafir’s decision to cut the tree.

Information security signifies information protection from aspects that result in modification, usage, access, and perusal without permission. The main principles of information security are non-repudiation, availability, integrity, confidential and authenticity. Similarly, risk management relates to information security and is referred to as evaluation, mitigation and assessment of risks. Risk management ensures that ICT supervisors can evaluate the costs of using protection measures in information management while achieving gains in a manner that supports the business goals. The paper explains the issue of information security and the main principles that are concerned with it. The issue of risk management and the ...
