Glossary

Term	Definition
accept	The term that is used to indicate that a secured task request has passed all security checks and may now be executed.
built-in function	Predefined function that comes with EPM Cloud for Linux.
character string list	A sequence of zero or more characters enclosed in double (") or single (') quotation marks.
character string list	An ordered list of character strings separated by commas and enclosed in curly braces ({}).
checksum	A unique value that is derived from an application. It can be used to determine if an application has been modified since the checksum value was created.
constant	A value that cannot be modified. A read-only variable is an example of a constant.
decimal integer	Base 10 numeric value (0, 1, 2, 3, 4, 5, 6, 7, 8, 9).
event log	The file that EPM Cloud for Linux uses to record information about each user task request that EPM Cloud for Linux processes.
environment variable	One of a set of Unix/Linux variables that define the environment that is passed to child processes.
false	A read-only EPM Cloud for Linux variable that is equal to an integer value of 0.
format command character	Used to insert variable values into character strings. Format command characters specify not only where to insert values, but also how to format the inserted values.
function	A stand-alone unit of security verification logic that performs a specific task. Procedures are generally used to implement repetitive tasks. The difference between a function and a procedure is that a function returns a value, whereas a procedure does not.
function scope	Determines whether a variable that is defined in one security policy function or procedure can be used by another security policy function or procedure. In EPM Cloud for Linux, functions and procedures have a global scope, meaning that variables that are used in one function or procedure can be used by any other function or procedure.
global variable	An EPM Cloud for Linux variable that applies to the EPM Cloud for Linux system, rather than to a specific task request.
hexadecimal integer	Base 16 integer value (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F).
index	A number that is used to access a specific element within a list variable.
integer	A numeric value; a member of the set of both positive and negative whole numbers.
I/O log	An EPM Cloud for Linux log that captures the input (keystroke), output, and error streams for an interactive Unix/Linux session.
LDAP connection	A special data type that is used to pass parameters to and from EPM Cloud for Linux LDAP functions.
LDAP message	A special data type that is used to pass parameters to and from EPM Cloud for Linux LDAP functions.
logging variables	Contain information that controls EPM Cloud for Linux logging activities.
log host	Machine on which the EPM Cloud for Linux log server runs. See pblogd.
manual accept	A task request can bypass security policy file processing and be manually accepted from the EPM Cloud for Linux web user interface.
octal integer	Base 8 integer value (0, 1, 2, 3, 4, 5, 6, 7).
operator	A symbol that performs a specific mathematical, relational, logical or other special function.
pblocald	The EPM Cloud for Linux daemon that is responsible for initiating task execution. See run host.
pblogd	When used, pblogd is responsible for saving log records to the appropriate event log files and I/O log files. pblogd is not a required EPM Cloud for Linux component. If pblogd is not used, then the policy server host and the run host write their own log records. See log host.
pbmasterd	The main EPM Cloud for Linux daemon. pbmasterd is responsible for determining whether requests should be allowed to run (accepted) or be terminated (rejected). See policy server host.
pbrun	The EPM Cloud for Linux daemon that intercepts task requests and determines if the task is subject to security policy rules. If so, then pbrun passes the request on to the policy server host. See submit host.
policy server host	Machine on which the main EPM Cloud for Linux daemon (pbmasterd) runs. See pbmasterd.
policy server security policy file	The security policy files invoked by policy server host to start security validation processing for a task.
procedure	A stand-alone unit of security verification logic that performs a specific task. Procedures are generally used to implement repetitive tasks. The difference between a function and a procedure is that a function returns a value, whereas a procedure does not.
read-only variable	A variable whose value cannot be changed; also known as a constant.
reject	The term used to indicate that a secured task request did not pass all security checks and so may not be executed.
run host	Machine on which the EPM Cloud for Linux task-execution daemon is run. See pblocald.
run variable	Modifiable version of a task information variable. These variables contain properties that affect task execution.
secured activity	An activity that is checked against EPM Cloud for Linux security policy files, before it is executed, to verify that it adheres to all security policy rules. See secured task.
secured task	A task that is checked against EPM Cloud for Linux security policy files, before they are executed, to verify that they adhere to all security policy rules. See secured activity.
security administrator	The person who is responsible for implementing a company’s network security policy.
security policy file	A file that contains the actual security checks that are used to determine whether a specific task should be accepted or rejected.
Security Policy Scripting Language	A C-like, interpreted programming language that is used to create security policy files.
security policy sub-file	A security policy file that is included by another security policy file. Security policy sub-files generally focus on specific areas of security verification processing.
security verification processing	The process of checking a task request against security policy files to determine if that task adheres to all security policy rules. The Policy Server host controls task verification processing.
special characters	Character combinations that are used in place of characters that cannot be typed directly with a keyboard.
submit host	Machine on which the EPM Cloud for Linux task-receiving component runs. See pbrun.
syslog	An interface that enables EPM Cloud for Linux to access the Unix/Linux logging daemon.
submitting user	The user who submitted the current task request.
task information variable	One of a set of variables that contain information about the current task. There are two types of task information variables: read-only variables and run variables.
task verification processing	The process of checking a task request against security policy files to determine if that task adheres to all security policy rules. The Policy Server host controls task verification processing.
task request	Any request to run a job.
true	A read-only EPM Cloud for Linux variable that is equal to an integer value of 1.
unsecured task	A task request that is not checked against EPM Cloud for Linux security policy files. Unsecured task requests are allowed to execute without first undergoing EPM Cloud for Linux task verification processing.
user-defined variable	Variable that is used within a security policy file to store information during task security verification processing.
user-written function	A stand-alone unit of security verification logic that performs a specific task. These units of code are written using the Security Policy Scripting Language. They are generally used to implement repetitive tasks. The difference between a function and a procedure is that a function returns a value, whereas a procedure does not.
user-written procedure	A stand-alone unit of security verification logic that performs a specific task. These units of code are written using the Security Policy Scripting Language. They are generally used to implement repetitive tasks. The difference between a function and a procedure is that a function returns a value, whereas a procedure does not.
variable data type	Defines the type of information that can be stored in a variable, as well as the types of operations that can be performed on a variable.
variable scope	Determines whether another security policy file can use a variable that is defined in one security policy file. In EPM Cloud for Linux, all variables have a global scope, meaning that after they are created, any security policy file can reference them.
