    The core software tools used by everyone in the agency include the Microsoft Word processing software; Microsoft Excel spreadsheet software; PowerPoint presentation graphics software; occasionally Access database software; and Outlook, an independent personal information manager. Outlook is used mainly as an e-mail application and for scheduling meetings, and contact management, and meeting scheduling requests and receipts of acceptance are a primary function that the entire agency uses. Associates' company e-mail accounts are accessed via Outlook, but it also includes a calendar, task manager, and note taking that is useful to keep track of individual schedules and meetings.

  3. Message confidentiality, Encrypt/Decrypt an arbitrary message using secret key cryptography including Base64 encoding.

    cannot be attached in the same way. Binary files need some sort of encoding process to be attached with STMP mail. And the most widely used encoding is Base64 [3]. Description of DES algorithm DES Encryption Process "DES has a very strong internal structure" [2]. The following figure presents an overview of the DES encryption process. Figure 1: DES Encryption process In DES encryption process 2 inputs are provided to the encryption function: a 64 bit plain text and a 56 bit secret key.

  4. Disaster Recover Plan

    The key elements are to analyze the risk. First there must be a list of all the possible risks that threaten system uptime and evaluate how imminent they are in your particular IT shop. Anything that can cause a system outage is a threat, from relatively common manmade threats like virus attacks and accidental data deletions to more rare natural threats like floods and fires. Determine which of the hearts are the most likely to occur and prioritize them using a simple system: rank each threat in two important categories, probability and impact.

  5. Website Review

    Ryanair use hot spot on their website for easy linking to other websites and for easy browsing. Ryanair watches the download speed on their website because if the web page took very long to open, many of ryanair pass ticket bookers may forget about booking with ryanair and book with another airline instead.

  6. You will see from your reading that the EU considers cybercrime as a very serious issue for business, in and between Member States. What do you see as the main potential threats posed by the widespread use in modern business of information technology and databases of personal information? How can the law be extended to protect against these threats without stifling technical innovation and business activity more than absolutely necessary?

    From a business perspective, forgery and fraud, as well as intellectual property breach, should both pose reasons for concern. E-commerce is reliant on building consumer trust, which would undoubting be breached if consumer data is leaked, shared or misused5. Hackers getting hold of sensitive information, setting off viruses and attacking consumer's data privacy, may not only significantly harm an organisation?s reputation, but may result in significant financial loss and compromise of sensitive information6. Breach of intellectual property, which is on the rise7, might on the other hand result in the organisation's material being misused without recognition, potentially having significant impact on competitive advantage and ability for first mover advantage.

  7. Why are governments so concerned about the use of cryptography in digital communications? What kind of laws and regulations have they brought in to try to deal with their concerns? How far do such efforts threaten the privacy that organisations need for conducting legitimate business?

    What kind of laws and regulations have they brought in to try to deal with their concerns? The Wassenaar agreement3 acts as the principal document on the encryption software export control regimes around the world. Its guidelines base restrictions on the key length of symmetric cryptographic products, and allow the free export of mass-market cryptographic software which complies with such provisions. OECD Guidelines for Cryptography Policy4 focus on trust, free choice and market-driven development of cryptographic methods. They promote the fundamental protection of privacy and personal data, lawful access to cryptographic keys and the need for a clear liability for cryptography users and service providers.

  8. Why has database security become such an important issue for companies these days? What are the key principles that should form the basis of a corporate strategy for information security?

    Through database security a company ensures the protection and security of systems, media and facilities which process and maintain information vital to its operation[1]. This is the reason for the increased importance to this issue by many corporations. In an effort to protect vital information which would be within the systems of these organizations database security over the years has become more stringent. With information such as personal details on employees, customers, and other individuals, their financial information or transactions, trade information, e-mails; videos, software, and loads of other information if access by the wrong persons can be detrimental to that individual and the organization also.
