What does ACI mean in UNCLASSIFIED
ACI (Access Control Instruction) is a command in the System Management Architecture (SMA) of IBM System z mainframes. It is used to control access to system resources, such as files, datasets, and devices. ACIs are defined in the System Authorization Facility (SAF) and are used by the Resource Access Control Facility (RACF) to enforce access control decisions.
ACI meaning in Unclassified in Miscellaneous
ACI mostly used in an acronym Unclassified in Category Miscellaneous that means Access Control Instruction
Shorthand: ACI,
Full Form: Access Control Instruction
For more information of "Access Control Instruction", see the section below.
Purpose of ACI
The purpose of an ACI is to specify the conditions under which a user or group is granted or denied access to a particular resource. ACIs can be used to control access based on a variety of factors, including:
- User ID
- Group membership
- Time of day
- Day of week
- IP address
Structure of an ACI
An ACI consists of the following components:
- Access List: A list of the users or groups that are granted or denied access to the resource.
- Resource Name: The name of the resource that the ACI applies to.
- Permission: The type of access that is being granted or denied.
- Condition: A logical expression that determines whether the ACI applies to the current request.
Example of an ACI
The following ACI grants the user JOHN read access to the file MYFILE during the hours of 9:00 AM to 5:00 PM:
ACI USER(JOHN) READ FILE(MYFILE) HOURS(0900-1700)Essential Questions and Answers on Access Control Instruction in "MISCELLANEOUS»UNFILED"
What is an Access Control Instruction (ACI)?
An Access Control Instruction (ACI) is a set of instructions that defines the access rights of a user to a particular object in a computer system. ACIs specify the operations that a user is permitted to perform on an object, such as reading, writing, or executing.
What are the different types of ACIs?
There are two main types of ACIs: discretionary ACIs (DACs) and mandatory ACIs (MACs). DACs are set by the owner of an object and can be modified by the owner at any time. MACs are set by the system administrator and cannot be modified by the owner of the object.
What is the difference between DACs and MACs?
DACs are more flexible than MACs because they allow the owner of an object to grant access to specific users or groups of users. MACs are more restrictive because they do not allow the owner of an object to grant access to users or groups of users that have not been explicitly authorized by the system administrator.
How are ACIs used in practice?
ACIs are used in a variety of ways to protect the confidentiality, integrity, and availability of data in computer systems. For example, ACIs can be used to:
- Prevent unauthorized users from accessing sensitive data
- Control who can make changes to important files
- Ensure that only authorized users can execute certain programs
What are some of the benefits of using ACIs?
ACIs provide a number of benefits, including:
- Improved security: ACIs help to protect data from unauthorized access by controlling who can access it and what they can do with it.
- Increased flexibility: DACs allow the owner of an object to grant access to specific users or groups of users, which provides greater flexibility than MACs.
- Enhanced accountability: ACIs help to track who has accessed an object and what they have done with it, which can be useful for auditing and troubleshooting purposes.
Final Words: ACIs are a powerful tool for controlling access to system resources on IBM System z mainframes. By defining ACIs, system administrators can ensure that only authorized users and groups have access to the resources they need.
