When things go wrong, it is necessary to know what has happened, and who is the cause. A system made of mutually distrustful parts should be stronger than a simple trusted system. For example, confidentiality is needed to protect passwords. The most significant aspect of the Wily Hacker incident is that the perpetrator was highly skilled and highly motivated. Although the Department of Defense (DOD) has articulated its requirements for controls to ensure confidentiality, there is no articulation for systems based on other requirements and management controls (discussed below)—individual accountability, separation of duty, auditability, and recovery. ), Using a computer system as an indirect aid in committing a criminal act, as in auto-dialing telephone numbers in search of answering modems, cracking another system's encrypted password files, or running an illicit business. Only in the presence of an enforceable policy can any protection or assurance occur. Are These Autonomous Vehicles Ready for Our World? As expertise and interconnection increase and as control procedures improve, the risks and likely threats will change.6 For example, given recent events, the frequency of Trojan horse and virus attacks is expected to increase. Y    States have also passed laws to protect privacy. This is impractical, and so security policies will always reflect trade-offs between cost and risk. Thus the specific requirements and controls for information security can vary. One break-in can set up the conditions for others, for example, by installing a virus. Ad hoc virus checkers, well known in the personal computer market, are also in demand. In a sampling of a collection of over 3,000 cases of computer system abuse, drawn from the media and personal reporting, the following types of attack, listed roughly in order of decreasing frequency, predominated (Neumann and Parker, 1989): Misusing authority, through activities such as improper acquisition of resources (reading of data, theft of programs), surreptitious modification, and denials of service, apparently by authorized users. On this basis the committee proposes the effort to define and articulate GSSP. Although Morris argued that the worm was an experiment unleashed without malice, he was convicted of a felony (the conviction may be appealed) under the Computer Fraud and Abuse Act (CFAA) of 1986, the first such conviction. 1 Security Requirements, Threats, and Concepts. There must be a way for individuals to correct or amend a record of identifiable information about them. Jump up to the previous page or down to the next one. Discarded media can be scavenged. The CIA triad has existed for a number of years and its concepts are well-known to security professionals. How, for example, can management ensure that its computer facilities are being used only for legitimate business purposes if the computer system contains security features that limit access to the files of individuals? H    This effect works in both directions: a service is not demanded if it is not available, but once it becomes available somewhere, it soon becomes wanted everywhere. Masquerading, as in one user impersonating another. We have compiled short descriptions of key concepts and a reading list for people who wish to enter into the world of digital health.. Physical attacks on equipment can compromise it. While five basic principles that make up a recognized privacy policy are summarized above, security, as it is discussed in this report, does not provide or enforce such a policy, except in the narrow sense of protecting a system from hostile intruders. The weight given to each of the three major requirements describing needs for information security—confidentiality, integrity, and availability—depends strongly on circumstances. To start with, I’d like to cover Eric Cole’s four basic security principles. Because security is a weak-link phenomenon, a security program must be multidimensional. ), the Electronic Funds Transfer Act of 1978 (15 U.S.C. Most purchasers of computer systems cannot afford to have a system designed from scratch to meet their needs, a circumstance that seems particularly true in the case of security needs. Computer systems as a mechanism provide no protection for people in these situations; as was observed above, computers, even very secure computers, are only a mechanism, not a policy. There are complex trade-offs among privacy, management control, and more general security controls. With Trojan horse attacks, for example, even legitimate and honest users of an owner mechanism can be tricked into disclosing secret data. It builds upon an introductory course on the fundamentals of networking, TCP/IP and internet, to investigate the concepts and practices for securing networks and network communications. Reasoning like the following is common: "Can't do it and still stay competitive"; "We've never had any trouble, so why worry"; "The vendor didn't put it in the product; there's nothing we can do. Recent cases about management perusing electronic mail messages that senders and receivers had believed were private amplify that debate (Communications Week, 1990a). the travel agency (Winans, 1990).
