CS 4550 Information Systems Security and Control When a computer connects to a network and engages in communication with other computers‚ it is essentially taking a risk. Internet security involves the protection of a computer’s Internet account and files from intrusion of an unknown user. Internet security has become an alarming issue for anyone connected to the net. This research paper argues the need for security over corporate intranets that have been dealing with the lack of security within

Data Encryption Standard In 1972‚ the NBS Institute for Computer Sciences and Technology (ICST) initiated a project in computer security‚ a subject then in its infancy. One of the first goals of the project was to develop a cryptographic algorithm standard that could be used to protect sensitive and valuable data during transmission and in storage. Prior to this NBS initiative‚ encryption had been largely the concern of military and intelligence organizations. The encryption algorithms‚ i.e.‚ the

because we often use common patterns for passwords/keys. This allows hackers to create a dictionary of commonly used passwords and preform a dictionary attack on the network. Symmetric encryption is the process of using a key to turn plain text into ciphertext. Once you have encrypted the text you can send it to the desired receiver. The receiver will have to have the key used to encrypt the text to decrypt the text. For this to happen you must share the key used to encrypt the text with the person/people

* Data Encryption Definition: -This is the encryption (encoding) of data for security purposes. How does it assist in securing data and maintaining its integrity? By encrypting‚ we change the original plaintext version of data into ciphertext‚ which is an unreadable format that will protect against unauthorized parties. Only those who possess the key to trigger the algorithm that will decrypt the data‚ hence making it readable‚ can access it. A higher bit
