  • Enterprise data centers contain the assets, applications, and data that are often targeted by electronic attacks. Endpoints such as data center servers are key objectives of malicious attacks and must be protected. The number of reported attacks, including those that affect data centers, continues to grow exponentially every year (CERT/CC Statistics 1988-2002, CSI/FBI 2001). Attacks against server farms can result in lost business for e-commerce and business-to-business applications, and the theft of confidential or proprietary information.

  • The most common Internet payment method for the business-to-consumer segment of electronic commerce is credit cards. However, the security of data transmitted over the Internet has been a major concern for customers. At present most companies use SSL (Secure Socket Layer) protocol to provide security and privacy. This protocol provides consumers a means to encrypt their order information. While providing a basic level of security this protocol has been breached and does not enjoy a high level of consumer confidence.

  • Applied Ethics is now acknowledged as a field of study in its own right. Much of its recent development has resulted from rethinking traditional medical ethics in the light of new moral problems arising out of advances in medical science and technology. Applied philosophers, ethicists and lawyers have devoted considerable energy to exploring the dilemmas emerging from modern health care practices and their effects on the practitioner–patient relationship.

  • Several factors should be considered along with the security categorization of the system confidentiality when making sanitization decisions. The cost versus benefit of a media sanitization process should be understood prior to a final decision. For instance, it may not be cost-effective to degauss inexpensive media such as diskettes. Even though clear or purge may be the recommended solution, it may be more cost-effective (considering training, tracking, and validation, etc) to destroy media rather than use one of the other options.

  • However, risks are inherent in any wireless technology. Some of these risks are similar to those of wired networks; some are exacerbated by wireless connectivity; some are new. Perhaps the most significant source of risks in wireless networks is that the technology’s underlying communications medium, the airwave, is open to intruders, making it the logical equivalent of an Ethernet port in the parking lot. The loss of confidentiality and integrity and the threat of denial of service (DoS) attacks are risks typically associated with wireless communications.

  • The information security concern regarding information disposal and media sanitization resides not in the media but in the recorded information. The issue of media disposal and sanitization is driven by the information placed intentionally or unintentionally on the media. With the advanced features of today’s operating systems, electronic media used on a system should be assumed to contain information commensurate with the security categorization of the system’s confidentiality.

  • Information systems capture, process, and store information using a wide variety of media. This information is not only located on the intended storage media but also on devices used to create, process, or transmit this information. These media may require special disposition in order to mitigate the risk of unauthorized disclosure of information and to ensure its confidentiality.
