|This table also looks at the checks which are present in the profile generator.||It looks at the default set values that need to be present in the profile generator.|
Q2) Elaborate on SAP security
Ans. The main role of SAP security is to provide the right access for users with business according to their responsibility and the authority that they hold. And permission is supposed to be given as per their roles in any of the organizations or departments.
Q3) What does one mean by roles as far as SAP security is concerned?
Ans. Roles are nothing but the transactional codes these are generally found in groups. These codes are given to take out a specific business assignment. So all these t-codes or roles require some specific privileges to implement any function as far as SAP security is concerned. And these special privileges are known as authorization.
Q4) Elaborate on how all users can be locked at the same time at SAP security?
Ans. It is possible to lock every user at the same time at SAP security. One has to implement a transactional code EWZ5 for doing this particular task.

Ans. There are certain steps that need to be taken prior to handing over or giving SAP_all to any of the users. These steps are necessary even when it has the approval of someone in the position of authority. These pre-requisite includes the following.
- The first is to enable the log of the audit. This can be done using a transactional code of sm 19.
- The second step is to retrieve the log of the audit. This can be done by using a transactional code of sm 20.
Q6) Elaborate on the meaning of authorization object class and the meaning of authorization object.
Ans. It is very essential to understand the meaning of the authorization object and that of the authorization object class. The authorization object is nothing but the groups of the field of authorization which looks after the function of a specific activity. Authorization is related to a specific action only whereas the field of authorization looks after the security administrators.

- This way one can delete numerous roles.
Q8) Explain the steps that need to be taken before one has to execute the Run system trace.
Ans. There are a few things that need to be done before one wants to execute the Run system trace. If one is going to trace the CPIC or the user id then prior to executing the Run system then one has to make sure that they said ID is given to someone that is either SAP_new or SAP_all.
This has to be done because this ensures that one is able to execute the work without any kind of checking failure by the authorization.

Ans. The transactional code which is used to lock the transaction from the execution is SM01.
Q11) What are the differences between a single role and a derived role?
Ans. The main difference is that of dealing with the transactional codes. When one deals with a single role then the transactional codes can be added or deleted easily. But if one is dealing with a derived role then a person is not able to add or delete any transactional code. This is the most important difference that one needs to know about a single role and derived role.
Q12) Within SAP security, what is SOD?
Ans. SOD stands for Segregation of Duties.
SOD is implemented in SAP to detect and prevent fraud during business transactions.

Q14) Explain what is user buffer?
Ans. Whenever a user logs into the SAP R/3 system, a user buffer is built where it has all the authorizations associated with the user. So basically, each user will have their user buffer.

If Krishna is a user and tries to log on to the system, then buffer would have all the authorization information under USER_KRISHNA_ROLE.
On the other hand, the user would fail to log on to the system, under the below scenarios:
For the user, authorization information doesn't exist in the user buffer
If the user buffer has many entries and it is flooded with authorization information. In this case, the number of entries can be restricted or limited by using a profile parameter called "auth/number_in_userbuffer".
Q15) For controlling the excess of entries what parameter is used in the user buffer?
Ans. The user buffer looks at the entries and it has to control the entries because it shouldn’t exceed. The parameter which is used is the following, auth/auth_number_in_userbuffer.
Q16) What is the number of transactional codes that can be given to a particular role?
Ans. A role can have a transactional code of as many as fourteen thousand.
Q17) In order to stock the illegal passwords what table is usually used?
Ans. In order to stock or accumulate the illegal password a table called USR40 is usually used. This particular table stores various patterns and arrangements of words that cannot be implemented while making any password.
Q18) What is known by PFCG Time dependency?
Ans. The PFCG time dependency is nothing but a report which is normally used for comparison of the user master. The PFCG Time dependency also makes sure to wipe away any profiles from the main record which seem to have expired and are of no use. There is also a transactional code that can be employed in order to execute this particular action. The transactional code which is used to do this is PFUD.
Q19) What is the role of users compare in SAP security?

Ans. The parameter which is used for deciding on the number of filters is as follows; rsau/no_of_filters.
Q27) Explain the derived role?
Ans. The derived role is an already present role. This role receives functions and menu structure which is present in the role referenced. This function of inheriting by the roles is only possible when no type of transactional code is assigned prior. The roles at the highest level will pass on the authorizations as a default to derived roles and this can be changed later on.
Certain levels are not passed to the derived roles and they need to be created newly this includes the organizational definitions as well as assignments of the user. Derived roles are well-designed and have a fixed functionality which means it has the same menus and transactions. But the characteristics are different as far as the level of organization is concerned.
Q28) Explain the working of a composite role?
Ans. On the other hand, a composite level role is like a big container which can collect numerous varied roles. These types of roles do not have any data about authorization. In case of any changes in the authorization since composite roles represent it, a data needs to be maintained regarding every role of every composite role.
The creation of the composite roles is only useful when some of the employees in the organization require authorization from various roles. So, in that case, the composite role can be set and the user can be assigned to that group. This is time saving rather than separately assigning every user to each different role.
When a user is assigned to one composite role, then during comparison they are spontaneously assigned to other elementary roles.
Q29) Which transactional codes are most commonly used in SAP security?
Ans. The transactional codes which are most commonly used in SAP security are SU53 for authorization of analysis, ST01 for trace, SUIM for the reports, SU01D for the display user, SU10 for bulk changes, PFCG to maintain roles, and SU01 for the creation or changing the user.

At any given point of time, it can be more than one profile associated with a role. By creating a role, a profile is automatically generated.
Q47) Explain what do you mean by "Profile Versions"?
Ans. If any parameter is modified within a profile, it automatically creates an updated version of the same profile. The process repeated whenever there is modification is made within a profile.

- SU10 - This T-code is used for handling users.
- SU01-This T-code is used for creating the user or changing the user.
- ST01 - This T-code is used for tracing the system.
- SU53- This T-code is used for analyzing authorization
Q50) Explain how a password rule can be enforced?
Ans. The process is very straight forward. If password rules need to be enforced then the user has to a profile parameter for the same. If this parameter is used then the password rules will be applied automatically.
Q51) Explain how to check the table logs and what are the T-codes to be used for the same?
Ans. To check whether the table logs are available, firstly one has to check whether the logging function is activatable or not for a particular table. This can be done by using Tcode SE13.
