Access Control Lists Sample Clauses

Access Control Lists. The access control to the resources and services can be focused on different levels. The first level is from a sensor-level where the node does not connect with any device which is not sharing a key (credential-access control). The second level is when the address is not in its Access Control List. This kind of access control is offered natively by protocols such as IEEE 802.15.4. For this project, the focus is on the access control at the discovery and Open Service architecture level, where in order to maintain privacy, it will not publish certain services. Specifically, the mechanism to carry out the access control from the discovery architecture is based on the definition of the access control list during the commissioning of the devices. This is done to specify the discoverable services and the security mechanisms implemented for the respective services. This allows the devices only to announce determined services to their digrectories. Xxxxxxx, a distributed approach is reached where policy decisions are hosted in the digrectory. In order to make it more scalable, general policies for all the sensors of a specific family and all the same type of services can be defined. This can be useful for deployments where a semantic layer is defined as presented in Section 6. For example, a common service for status monitoring, denominated “status” which checks the status from the sensors, i.e. if it is online and if it is the last value can be defined. This service is useful as a callback when the clients are not bounding the service, and when they need to verify that the service is reachable.

Access Control Lists. Access control lists are the representation of object rights as a table of subjects mapped to their individual rights over the object. In fact, The ACL identifies the individual users or groups who may access the file. ACLs correspond to individual columns in the ACM. ACLs are implemented differently on different systems. For example, in a UNIX-based trusted system that uses the UNIX security kernel developed by Atlanta-based SecureWare, PAYROLL would be protected with ACLs in the form: where: ‹xxxx.acct, r› ‹xxxx.xxx, rw›  xxxx and xxxx are login IDs of users who are allowed access to the PAYROLL file.  acct and pay are group IDs of the users.  r and w indicate the type of access allowed; r means that the user can only read PAYROLL, w that he or she can also change it. If xxxx is in the acct group, he can only read the file. If he belongs to any other group, by default he has no access. Similarly, if xxxx is in the pay group, she can read and write the file. The following figure illustrates how ACLs control file access:

  • Access Control Supplier will maintain an appropriate access control policy that is designed to restrict access to Accenture Data and Supplier assets to authorized Personnel. Supplier will require that all accounts have complex passwords that contain letters, numbers, and special characters, be changed at least every 90 days, and have a minimum length of 8 characters.

  • Access Controls a. Authorized Access - DST shall have controls that are designed to maintain the logical separation such that access to systems hosting Fund Data and/or being used to provide services to Fund will uniquely identify each individual requiring access, grant access only to authorized personnel based on the principle of least privileges, and prevent unauthorized access to Fund Data.

  • Data Access Control Persons entitled to use data processing systems gain access only to the Personal Data that they have a right to access, and Personal Data must not be read, copied, modified or removed without authorization in the course of processing, use and storage. Measures: • As part of the SAP Security Policy, Personal Data requires at least the same protection level as “confidential” information according to the SAP Information Classification standard. • Access to Personal Data is granted on a need-to-know basis. Personnel have access to the information that they require in order to fulfill their duty. SAP uses authorization concepts that document grant processes and assigned roles per account (user ID). All Customer Data is protected in accordance with the SAP Security Policy. • All production servers are operated in the Data Centers or in secure server rooms. Security measures that protect applications processing Personal Data are regularly checked. To this end, SAP conducts internal and external security checks and penetration tests on its IT systems. • SAP does not allow the installation of software that has not been approved by SAP. • An SAP security standard governs how data and data carriers are deleted or destroyed once they are no longer required.

  • System Access Control Data processing systems used to provide the Cloud Service must be prevented from being used without authorization. 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.

  • Physical Access Control Unauthorized persons are prevented from gaining physical access to premises, buildings or rooms where data processing systems that process and/or use Personal Data are located.

Username must be promptly disabled, deleted, or the password changed upon the transfer or termination of an employee with knowledge of the password, at maximum within 24 hours. Passwords are not to be shared. Passwords must be at least eight characters and must be a non-dictionary word. Passwords must not be stored in readable format on the computer. Passwords must be changed every 90 days, preferably every 60 days. Passwords must be changed if revealed or compromised. Passwords must be composed of characters from at least three of the following four groups from the standard keyboard: • Upper case letters (A-Z) • Lower case letters (a-z) • Arabic numerals (0-9) • Non-alphanumeric characters (punctuation symbols)
