  1. Computer security policy

    A computer security policy defines the goals and elements of an organization s computer systems. The definition can be highly formal or informal. Security policies are enforced by organizational policies or security mechanisms. A technical implementation defines whether a computer system is secure or insecure . These formal policy models can be categorized into the core security principles of Confidentiality, Integrity and Availability. For example the Bell La Padula model is a confidentiality policy model , whereas Biba model is an integrity policy model . Formal description If a system is regarded as a Finite state automaton finite state automaton with a set of transitions operations that change the system s state, then a security policy can be seen as a statement that partitions these states into authorized and unauthorized ones. Given this simple definition one can define a secure system as one that starts in an authorized state and will never enter an unauthorized state. Formal policy models Confidentiality policy model Bell La Padula model Integrity policies model Biba model Clark Wilson model Hybrid policy model Chinese wall Computer science Chinese Wall Also known as Brewer and Nash model Policy languages To represent a concrete policy especially for automated enforcement of it, a language representation is needed.

  1. Conceptual model (computer science)

    A mental model captures ideas in a problem domain , while a conceptual model represents concepts entities and relationships between them. A Conceptual model in the field of computer science is also known as a domain model . Conceptual modeling should not be confused with other modeling disciplines such as data modelling , logical modelling and physical modelling . The conceptual model is explicitly chosen to be independent of design or implementation concerns, for example, concurrency or data storage. The aim of a conceptual model is to express the meaning of terms and concepts used by domain experts to discuss the problem, and to find the correct relationships between different concepts. The conceptual model attempts to clarify the meaning of various, usually ambiguous terms, and ensure that problems with different interpretations of the terms and concepts cannot occur. Such differing interpretations could easily cause confusion amongst stakeholders, especially those responsible for designing and implementing a solution, where the conceptual model provides a key artifact of business understanding and clarity. Once the domain concepts have been modeled, the model becomes a stability ... of the conceptual model can be mapped into physical design or implementation constructs using either manual or Model driven development automated code generation approaches .

  1. Shibboleth (computer security)

    other uses2 Shibboleth Unreferenced date December 2009 In the field of computer security , the word shibboleth means to test something, and based on that response to take a particular course of action. The most commonly seen usage is logging on to a computer with a password or other type of credential . If the password is entered correctly, the user can log on to the computer if the password entered is incorrect, access is blocked. There are various classes of computer security related shibboleth. Class 1 Something known perhaps a password or another fact. Class 2 Something held a card or a physical tag of some kind. Class 3 Something that is a biometric feature such as a fingerprint or an iris scan. The three classes are also jokingly referred to as something you forget , something you lose , and something you cease to be . In general, it is considered more secure to combine various classes of shibboleth, rather than using the approach of just requiring a class 1 shibboleth that is common today. So for example, a high security system might require an authorized user to login by entering a password, swiping an encoded card and passing a biometric test.

  1. Human?computer interaction (security)

    HCISec is the study of interaction between humans and computers, or HCI , specifically as it pertains to information security . Its aim, in plain terms, is to improve the usability of security features in end user applications. Unlike HCI, which has roots in the early days of Xerox PARC during the 1970s, HCISec is a nascent field of study by comparison. Not surprisingly, interest in this topic tracks with that of Internet security , which has become an area of broad public concern only in very recent years. Historically, security features exhibit poor usability for reasons that include they were added in casual afterthought they were hastily patched in to address newly discovered security bug s they address very complex use case s without the benefit of a Wizard software software wizard their interface designers lacked understanding of related security concepts their interface designers were not usability experts often meaning they were the application developers themselves See also Human computer interaction Further reading http www.simson.net thesis Design Principles and Patterns for Computer Systems That Are Simultaneously Secure and Usable , by Simson Garfinkel External links http gaudior.net alma biblio.html HCISec Bibliography http tech.groups.yahoo.com group hcisec HCISec Yahoo Group http www.usablesecurity.com Usable Security Blog Category Human communication Category Human computer interaction Category Computer security ...   more details

  1. Stepping stone (computer security)

    Orphan date February 2009 Unreferenced date December 2010 A stepping stone StSt is a type of computer security measure which consists of placing several logical security systems, used as authentication servers, in a serial disposition to emulate a physical narrow channel, analogous to a physical path formed by stepping stone s used to cross a river. Using this system, it is possible to apply a granular control over each system acting as a stone , establishing different risk levels as so many systems which have been placed in the series. For example, to grant a user with access to an OpenSSH server, for executing an application in a high security environment, we could put a front end system such as a Sun Solaris with a Citrix Metaframe in the 1st security layer. The 2nd layer could be an MS Terminal Services with an Secure Shell SSH Client. Thirdly, the last layer could be based on a Linux system with an OpenSSH Server, which would grant access to the final application. Every system could have a common secure system to log on as SecureID RSA SecureID , X.509 certificates based, Challenge response challenge response systems, etc. or a mixture of them. It depends on the risk analysis over the environment treated. This computer security practice tends to decrease the system usability and is hard to maintain, so it should be implemented only in high security environments. This practice could be considered as part of a well known security principle Defense in Depth computing Security In Depth , in this case, applied to the access control, adding logical barriers and trenches, composed by diverse authentication systems.

  1. Principal (computer security)

    Wikify date September 2010 A principal in Computer Science is an entity that can be Authentication authenticated by a computer system or network. Authentication is the process of validating and confirming the identity of such an entity. Principals, in addition to being able to be authenticated, are typically capable of being assigned rights and privileges over resources in the network. Together, the ability to authenticate a principal and to grant rights and privileges to it allow the entity represented by the principal to access resources on the network. The two most common types of principals are users representing physical persons or functional accounts used for representing a computational entity and computers, which correspond to physical or virtual systems connected to the network. Some systems allow for other types of principals such as those representing services without an associated user account . Typically a principal has an associated identifier such as a security identifier that allows for the principal to be referenced for purposes of identification or assignment of properties and permissions. This concept is also referred as security principal in the Java programming language Java or Microsoft literature ref name technet http technet.microsoft.com en us library cc780957 WS.10 .aspx What Are Security Principals? , technet.microsoft.com , 28 March 2003. ref .
