Definition of Mandatory Access Control Sample Clauses

Definition of Mandatory Access Control. Mandatory access control (MAC) is the strictest of all access control models. It is suitable only for organizations connected with extremely high security and is, above all, used by the government and the US Department of Defence. The main idea of MAC is that a system mechanism (e.g., the operating system) controls access to an object and an individual user cannot alter that access. Neither the subject nor the owner of the object can determine whether access is granted. The system mechanism will check information associated with both the subject and the object to determine whether the subject should access the object. Therefore, the main goals of MAC are:  Preserve confidentiality and integrity of information  Prevent some types of Trojan horse attacks  Prevent that a user can change security attributes In order to achieve the goal of preserving both confidentiality and integrity of information, two types of mandatory policies are implemented:  Secrecy policies: controls the direct and indirect flows of information to the purpose of preventing leakages to unauthorized subjects  Integrity policies: controls the direct and indirect flows of information to the purpose of preventing unauthorized altering of objects Through the years, different MAC implementations have been defined, but most of them are variants of the US Department of Defence multitiered security policy (MLS). The idea of MLS is that each object in the system (e.g. a document) possesses a classification, while each subject of the system (e.g. a technician) possesses a clearance. In order to determine whether a subject is allowed to access an object, the subjects’ clearance is compared to the objects classification. Both classification and clearance are made up of two components:  A security level (or classification), there are four hierarchical levels (based on the Department of Defence multi-level security policy): UNCLASSIFIED < CONFIDENTIAL < SECRET < TOPSECRET  A set of one or more non-hierarchical categories (or clearance) depending on the area to which an object may belong: o In a banking environment: {Corporate, branch, departments} o In a commercial environment: {Accounting, Marketing, Sales, R&D}

Measures: • Multiple authorization levels are used when granting access to sensitive systems, including those storing and processing Personal Data. Authorizations are managed via defined processes according to the SAP Security Policy • All personnel access SAP’s systems with a unique identifier (user ID). • SAP has procedures in place so that requested authorization changes are implemented only in accordance with the SAP Security Policy (for example, no rights are granted without authorization). In case personnel leaves the company, their access rights are revoked. • SAP has established a password policy that prohibits the sharing of passwords, governs responses to password disclosure, and requires passwords to be changed on a regular basis and default passwords to be altered. Personalized user IDs are assigned for authentication. All passwords must fulfill defined minimum requirements and are stored in encrypted form. In the case of domain passwords, the system forces a password change every six months in compliance with the requirements for complex passwords. Each computer has a password-protected screensaver. • The company network is protected from the public network by firewalls. • SAP uses up–to-date antivirus software at access points to the company network (for e-mail accounts), as well as on all file servers and all workstations. • Security patch management is implemented to provide regular and periodic deployment of relevant security updates. Full remote access to SAP’s corporate network and critical infrastructure is protected by strong authentication.
