Dimensioning[ edit ] Dimensioning a new network determines the minimum capacity requirements that will still allow the Teletraffic Grade of Service GoS requirements to be met. A dimensioning rule is that the planner must ensure that the traffic load should never approach a load of percent.
Maintenance worker Site and system Worker in the billing department who has access to information systems but not to clinical information Data and system Vendor or consultant with remote access privileges Site, system, and data Care provider such as doctor or nurse Technical Capability.
The technical capability of an attacker is, in general, independent of the characteristics of access outlined above: The technical capabilities of potential attackers can be characterized by three broad categories: Aspiring attackers are individuals with little or no computer expertise, but with ambitions and desires to learn more.
They learn about attacks from popular literature, much of it published by organizations that cater to the survivalist and antiestablishment trade. The techniques they use are relatively unsophisticated and include the following: Researching the target site by reading open literature and scouting the location; Masquerading as an employee or other authorized individual to gain information or access; Guessing passwords, locating passwords written on calendars or elsewhere, or watching users enter their passwords; Searching trash bins for information on security practices and mechanisms; and Gaining entry to the desired location by gaining employment as a temporary employee, dressing as a custodial or professional staff member, or using some other method.
Script runners are an Internet phenomenon. These are individuals who obtain standard, scripted attacks and run them against information systems to which they desire entry. Protecting Electronic Health Information. The National Academies Press.
The current inventory of scripts operates primarily in standard Internet environments; given the rush of other vendors e. Accomplished attackers are the most formidable threat: For a health care organization, the worst-case future scenario is an accomplished attacker gaining entry via the Internet to an information system that allows access to patient health information.
The technical capability of attackers at each level in this hierarchy is constantly evolving and improving. Techniques that just a few years ago were the exclusive purview of accomplished attackers have moved to the script runner stage and will shortly be available to aspiring attackers.
Mechanisms for countering these threats must therefore also evolve and improve, which implies a continuing intellectual and financial investment in security technology. Levels of Threat to Information in Health Care Organizations During its site visits, the committee discerned a number of distinct types of organizational threats described by different combinations of motive, resources, access, and technical capability.
They are categorized here by levels numbered one through five with five being the most sophisticated.
Insiders who make ''innocent" mistakes and cause accidental disclosures. Accidental disclosure of personal information—probably the most common source of breached privacy—happens in myriad ways, such as overheard conversations between care providers in the corridor or elevator, a laboratory technician's noticing test results for an acquaintance among laboratory tests being processed, information left on the screen of a computer in a nursing station so that a passerby can see it, misaddressed e-mail or fax messages, or misfiled and misclassified data.
Insiders who abuse their record access privileges.
Examples of this threat include individuals who have authorized access to health data whether through on-site or off-site facilities and who violate the trust associated with that access. Health care workers are subject to curiosity in accessing information they have neither the need nor the right to know.
Although no overall statistics are available to indicate the scope of the problem, discussions with employees during site visits uncovered many cases in which health care workers have accessed information about the Page 60 Share Cite Suggested Citation: There are reports of health care workers accessing health records to determine the possibility of sexually transmitted diseases in colleagues with whom they were having a relationship—or in people with whom former spouses were having relationships.
Potentially embarrassing health information e. Insiders who knowingly access information for spite or for profit. This type of threat arises when an attacker has authorization to some part of the system but not to the desired data and through technical or other means gains unauthorized access to that data.Physical Network Security By Erik Rodriguez.
This article describes, in some detail, a physical security audit. Physical security is often over-looked and should be . Access Control: each covered component will ensure that security controls are in place to protect the integrity and confidentiality of ePHI residing on computer systems, including applications, databases, workstations, servers, and network equipment using procedures associated with the University Information Security Policy.
[Addresses. This Security Plan constitutes the "Standard Operating Procedures" relating to physical, cyber, and procedural security for all (Utility) hydro projects.
Network planning and design is an iterative process, encompassing topological design, network-synthesis, and network-realization, and is aimed at ensuring that a new telecommunications network or service meets the needs of the subscriber and operator. Draft a page description of the physical and network security issues and concerns at each Riordan plant. Using various Internet sources, find an article or website on an information security topic that is of interest to you. Network security, especially as it relates to the biggest network of all, the Internet, has emerged as one of today's highest-profile information security issues. Many education organizations have already connected their computing resources into a single network; others are in the process of doing so.
It contains a comprehensive overview of the (Utility)'s security program, and in some sections, makes reference to other relevant plans and procedures. Concerns over the privacy and security of electronic health information fall into two general categories: (1) concerns about inappropriate releases of information from individual organizations and (2) concerns about the systemic flows of information throughout the health care and related industries.
