M2 - Explain the way that data transmitted over a network can be protected by encryption. Below‚ I will explain the way that data transmitted over a network can be encrypted to provide protection. I will explain what encryption entails‚ how data is transmitted‚ and why it is important to encrypt private data to ensure its protection. What Does Encryption Entail and How Does It Work? Encryption entails rearranging data in such a way that only the owner of both the encryption and decryption

Locard’s Exchange Principle and the use of Fingerprints: Edmond Locard (1877-1966) was a French scientist specialised in both medicine and law. Inspired by the work of Hans Gross‚ it was Edmond that created the concept that all objects of any material should leave traces of itself upon whatever it touches‚ even if it is the minutest amount‚ simply put as “Every Contact leaves a trace‚” Locard (1923). This is commonly known as Locard’s Exchange Principle. He believed that in circumstances such as

After the preservation phase‚ forensics are required to locate and identify any evidence that can be used to aid the crime case. There are several locations where evidence are usually found such as in the hard drive on the user’s personal computer‚ laptop‚ smart phone or tablet (ACPO‚ 2012). It is also critical that forensics are aware of the intention of the particular investigation. This aids in the forensics’ efforts of locating digital evidences that are relevant to the case. For example‚ in

Can you imagine a machine so important that without it‚ democracy wouldn’t exist. A machine that has undoubtedly changed the face of the Earth and the modern world whether we know it or not. If it wasn’t for this device‚ generations ahead of its time‚ we would still be under the rule of Hitler in an imperialist dictatorship. This device is none other than the Turing Machine. It is a machine that was created in 1912 and named after its creator Alan Turing. The machine was a result of the Allies need

Question 2b: Some Windows products do not allow the use of international characters in the username or password. These characters may be part of an international alphabet or Asian characters. Research the characters that are allowed in recent version of Windows and cite your sources. Describe the advantage to the operating system of limiting the character set for usernames and passwords‚ and whether or not you suggest an alternative. Introduction to character set: Characters set are divided

Book review Digital Fortress is a fairly well-written and entertaining novel. The main storyline is based upon a hush-hush operation within the NSA to obtain and or destroy the only existing copies of a pass-key that‚ if made public‚ could enable the use of an encryption program that would create coded messages that would be entirely unbreakable thereby rendering the NSA obsolete and allowing undecipherable communications between terrorist organizations and crime rings throughout the world.

Tips for creating strong passwords and passphrases A password is a string of characters used to access information or a computer. Passphrases are typically longer than passwords‚ for added security‚ and contain multiple words that create a phrase. Passwords and passphrases help prevent unauthorized people from accessing files‚ programs‚ and other resources. When you create a password or passphrase‚ you should make it strong‚ which means it’s difficult to guess or crack. It’s a good idea to use strong

The RSA Algorithm Evgeny Milanov 3 June 2009 In 1978‚ Ron Rivest‚ Adi Shamir‚ and Leonard Adleman introduced a cryptographic algorithm‚ which was essentially to replace the less secure National Bureau of Standards (NBS) algorithm. Most importantly‚ RSA implements a public-key cryptosystem‚ as well as digital signatures. RSA is motivated by the published works of Diffie and Hellman from several years before‚ who described the idea of such an algorithm‚ but never truly developed it. Introduced at the
