SAP Security

Purpose of Security: Assign users rights to perform job tasks that they need to do.

Prohibit users from doing tasks that they are not supposed to do.

Objectives of presentation Define key security concepts

Examine relationship between user and security concepts

Apply concepts to real situations

SAP AG


SAP Security

Security is performed at the object level 30 + Object classes, such as Basis Administration, FI, MM Master Data

(View Objects within classes by using SU03)

About 500 + objects within the 30 + classes

SAP Security works on a pass-fail system. It checks constraints until if finds a failure.

Levels of Setting: Authorization Object in the form of authorization (test on an object)

Profile (sets of authorizations)

User ID

Authorization Object: something in the system that potentially needs protecting (company code, document type, etc.)

Fields: attributes that can be used to set protection (1-10 fields per object that vary with object) Activity: such as create, update, delete, view..

Authorization Group: Values that the object needs

IDOC Type

Profile (set of authorizations) User Master Record (all profiles for that user)

Authorization: Set of specified values for fields in an Authorization Object = test conditions for the object

Standard Authorizations provided by SAP Object: F_BKPF_BED: Customer Account

Activity: *

Account Group: *

Never Change or Delete an SAP authorization Custom Authorizations (should start with Z)

SAP AG


SAP Security Example

Object Class: Financial Accounting Authorization: ZS_D01 Authorization Object: F_BKPF_BED: Customer

Account Activity: 01-03, 10 (create, change, print,post) Account Group: CALF, HAW SAP programs perform AUTHORITY-CHECK on objects

for values in fields

SAP AG


SAP Security: Creating an Authorization

Create a name for the authorization Start with the letter Z

Don’t use underscore as second character

Example: ZS_D01

Use SU03 to create the authorization (Tools --> Administration -->Maintain Users) Create (first icon: sheet of paper)

Maintain values sets the values you want

Save

Activate

SAP Security

Profile: Set of Authorization Objects Simple Profile: 1 Authorization Object Composite Profile: more than one authorization object Can have a composite made up of composites

SAP Security

SAP Standard Profile: F_BKPF_KANZ (Display vendor Accounts)

Custom Profile: AA:FIAR_M01 Create profile then activate Copy from existing profile then rename To look at, change or create profiles use SU02

SAP AG


SAP Security

Standard Profiles common to all SAP installations SAP_ALL (unlimited access to system)

SAP_NEW (allows older standard profiles to work in newer SAP releases)

S_A_SYSTEM: System Administrator

S_A_SHOW: Display authorizations only

SAP AG


SAP Security: Users

User Profiles assign profiles to specific user IDs Users can belong to Group, I.e. ABAP Developers, C&I

Admin Can’t assign authorizations to groups only to individual

users User Group is a field in some authorization objects Groups useful to separate responsibility, I.e. more than

one security administrator, each responsible for a group of users

SAP AG


SAP Security: Users

Name the ID for the User Set the password Lock/unlock the account Define time period for the ID Set default printer and printing rights Define PIDs (Parameters) Define profiles

SAP AG


SAP Security: Users

Rules for setting passwords: Must be at least 3 characters

Can not begin with ! or ?

First 3 characters can not be a sequence of 3 characters in user ID. I.e. if by user id is gcorbitt, my password can not contain orb, or cor.

First 3 characters can not be the same, I.e. ccc

Can not use “pass” or “sap”

SAP AG


SAP Security: Users

PID :Parameter ID Example of parameter:

default menu options, I.e. fast entry

default currency

posting period options

SAP AG


SAP Security: Users

User types Dialog

BDC: inbound interfaces (I.e. data coming in from a legacy system)

CPIC: machine to machine ID connect through UNIX (I.e. EDI inbound or outbound)

BDC and CPIC do not have expiration dates on the passwords

SAP AG


SAP Security: Transactions SU01: Creates and maintains users SU02: Creates and maintains profiles SU53: Displays LAST authorization failure ST01: Traces keystrokes SU03: Lists objects and classes SM04: Monitors user activity SE16: Looks at specific tables in SAP (T003 = auth. group) SA38: Looks at programs (AUTHORITY-CHECK) SU12: Deletes all users (usually disabled) SU10: Adds or deletes a profile to all users

SAP AG


SAP Security: Coming Attractions

SAP Profile Generator (31.G, R4) Makes it easier to track and maintain multiple profiles per user

Uses menu paths to create authorizations or profiles

Activity Groups similar to our functional profiles

Activity Group Maintenance (31.G) Allows for profile updates, parameter settings by group instead of by

individual user

Hopefully allows for resetting expiration, start dates, printer options, etc. by groups of users instead of one user at a time

SAP AG


Application of SAP Security to Classroom Activity

Define what “jobs” or roles we want the students to have per class --functional profiles

Set up authorizations for each job or role - job profiles Assign job profiles to users Document existing authorizations for Display and Create

Activities for each “application” object Create authorizations for Display and Create where

missing Create a standard profile that any user could have (view

only to all modules)
