RACF Security Policies and Profile Overview

The foundation of the RACF security is the security policies and profile that are in place. These elements stipulate who can use which resource, in which manner, and under which conditions to help control users and groups in your IT environment.

Security Policies

The RACF security policies refer to the major policies on how access to resources is regulated and even controlled. It can be said that these policies may be adjusted to the unique security needs of your organization depending on the relevant standards such as legal requirements and industry trends as well as the internal norms established in the organization.

Some common RACF security policy types include:Some common RACF security policy types include:

• Discretionary Access Control (DAC): Determines what specific files or folders a particular user or group of users can or cannot view or modify.
• Mandatory Access Control (MAC): Imposes security labels and classification to resources and only permits a user to access what his security clearance allows.
• Program Control: Limits the running of certain classes or instructions and prevents the use of risky or forbidden code.
• Auditing and Logging: Determines the settings for the security event log and the audit trail, which document attempts to gain access to the system and other security occurrences.

RACF Profiles

We can define RACF profiles as the concrete settings which enforce the security measures in your IT setting. These profiles describe the security characteristics including access modes, rights, and attributes for data sets, transactions and system services.

Some common RACF profile types include:Some common RACF profile types include:

• User Profiles: Specifies the user types and their rights to the system as well as security properties.
• Group Profiles: It is useful for grouping users in a logical manner and gives better control over all access rights in one place.
• Data Set Profiles: It defines the access control and security properties of the data sets and other file oriented entities.
• Resource Profiles: Specifies the security policies and access rights of the different system resources at the transaction, application, or even the system function levels.

Now when you know about the RACF security policies and profiles, it will be easier for you to build a strong security strategy, which will suit your company’s needs and follow the standards.

RACF administration and management

Proper RACF usage and management are also very important to maintain the security of your IT system and its compliance with certain standards. As an experienced RACF administrator, you will be responsible for a range of tasks, including:As an experienced RACF administrator, you will be responsible for a range of tasks, including:
