A.Mandatory access control B.Role-based access control C.Attribute-based access control D.Discretionary access control - ✔✔-Attribute-based access control Lesson: Authorization and Access Control Objective: More Advanced States that we should allow only the bare minimum access required in order for a given party (person, user account, or process) to perform a needed functionality - ✔✔-Principle of least privilege Typically built to a certain resource, these contain the identifiers of the party allowed to access the resource and what the party is allowed to do. - ✔✔-Access control lists (ACLs) In this method of security, a person's capabilities are oriented around the use of a token that controls their access (e.g. a personal badge) - ✔✔-Capability-based security A type of attack that is more common in systems that use ACLs rather than capabilities - ✔✔-The confused deputy problem A type of attack that misuses the authority of the browser on the user's computer - ✔✔-Cross-site request forgery (CSRF) Access is determined by the owner of the resource in question - ✔✔-Discretionary access control (DAC) Similar to MAC in that access controls are set by an authority responsible for doing so, rather than by the owner of the resource. In this model, access is based on the role the individual is performing - ✔✔- Role-based access control (RBAC) Access is based on attributes (of a person, a resource, or an environment) - ✔✔-Attribute-based access control Designed to prevent conflicts of interest; commonly used in industries that handle sensitive data. Three main resource classes are considered in this model: objects, company groups, and conflict classes. - ✔✔- The Brewer and Nash model A combination of DAC and MAC, primarily concerned with the confidentiality of the resource. Two security properties define how information can flow to and from the resource: the simple security property and the * property. - ✔✔-The Bell-LaPadula model Primarily concerned with protecting the integrity of data, even at the expense of confidentiality. Two security rules: the simple integrity axiom and the * integrity axiom. - ✔✔-The Biba model An access control model that includes many tiers of security and is used extensively by military and government organizations and those that handle data of a very sensitive nature - ✔✔-Multilevel access control model What process ensures compliance with applicable laws, policies, and other bodies of administrative control, and detects misuse?

Shares the same block modes that DES uses and also includes other modes such as XEX-based Tweaked CodeBook (TCB) mode - ✔✔-AES Also known as public key cryptography, this method uses two keys: a public key and a private key. - ✔✔- Asymmetric key cryptography Uses the RSA algorithm, an asymmetric algorithm, to secure web and email traffic - ✔✔-Secure Sockets Layer (SSL) protocol Also referred to as message digests, these functions do [Show More]
