This report documents the results of the SAP Security Optimization service in the following sections: - General information about the SAP Security Optimization service - Action list in which the results are summarized and prioritized - Detailed explanation of the findings 3 General information about the SAP Security Optimization Service The following contains general information about SAP Security Optimization that will help you to understand and apply the report. Objective of the SAP Security Optimization Service The objectives of SAP Security Optimization are: - To analyze the technical configuration of your SAP system for security risks - To provide recommendations for implementing measures to mitigate security risks - To provide a compressed overview of the implemented security level - To enable you to protect your business systems from typical security risks SAP Security Optimization Self-Service, <Date> 5

6 The security checks of SAP Security Optimization are performed for the following security aspects: - Availability: ensuring that a system is operational and functional at any given moment - Integrity: ensuring that data is valid and cannot be compromised - Authenticity: ensuring that users are the persons they claim to be - Confidentiality: ensuring that information is not accessed by unauthorized persons - Compliance: ensuring that the system security set-up is in accordance with established guidelines Scope of SAP Security Optimization SAP Security Optimization includes a collection of several hundred checks. These checks identify security vulnerabilities in the current set-up and configuration of mysap Technology. The checks are performed on the SAP software layer. For a security analysis of the underlying operating system and database, consult your vendor; for a security analysis of the network, contact your preferred network security provider. The Security Optimization Service is a highly automated, remote support service. For this reason, the service cannot cover customer-specific aspects that require a detailed on-site analysis, such as the following checks: - Segregation of duties for business-critical processes - Security organization (organizational security) - Security administration processes (operational security) For a complete overview of existing security risks to your business system, the topics listed above have to be taken into consideration. SAP's Security Consulting Team can assist you with individual on-site consulting services to obtain guidance on the security aspects. How to read this report The objective of this report is to document the vulnerabilities that have been detected by the SAP Security Optimization service. Since we perform several hundred checks in this support service, only the actual weaknesses are listed in the report so that it is concise; checks whose results were positive are not mentioned. In some checks, unexpected users with critical authorizations are determined. If you have indicated in the questionnaire that you want the user ID and the names of the users to be printed, they are listed in the findings of these checks. Note that no more than 30 users are listed - even if more users have been found - to keep the report concise. If you want to determine all users who have this authorization, you can do so in transaction ST14. For more information about using this transaction, see SAP Note For each productive client analyzed, the maximum number of users printed is 20. For other clients (for example 000 or 066), the maximum number of users printed for each client is 20 divided by the number of checked clients. This ensures that examples of all clients are printed. The number of counted users that we print is reduced by the number of superusers that we found in the system (check 0022). Since superusers (users with the SAP_ALL profile) have all authorizations, they are printed only once at the beginning of the report. The user types in the report are having the following meaning: A = Dialog C = Communication B = System S = Service L = Reference To enable you to identify major security weaknesses and to prioritize the measures to be implemented, an evaluated risk is determined for each check. The evaluated risk is calculated by the severity and the probability of a security violation. The meaning of the evaluated risk is as follows: - HIGH: The severity is high and the probability is high or the severity is high and the probability is medium or the severity is medium and the probability is high - Medium: The severity is high and the probability is low or the severity is medium and the probability is medium or the severity is low and the probability is high - Low: The severity is medium and the probability is low or the severity is low and the probability is medium or the severity is low and the probability is low How to implement the recommended security measures To protect your SAP system from security violations, we recommend that you implement the measures proposed in this report. To do so, proceed as follows: SAP Security Optimization Self-Service, <Date> 6

7 1. Read this report carefully. 2. Double-check that the identified risks actually apply to your system. (Note that incomplete data in the questionnaire can result in the report indicating more vulnerabilities than are actually in your system.) 3. Prioritize the risks and determine those that are acceptable for you. 4. Determine the effort to implement appropriate measures. 5. If required, perform a cost-benefit analysis before applying the measures. 6. Plan and implement the measures. Do not implement the recommended measures without considering them first. Double-check the impact of the recommended measures before applying them to your system. For example, implementing a new password policy might be confusing to end users if they have not been notified about the new policy. How to obtain support for the implementation In some cases, you may not have the required resources to implement the recommended security measures. If you need support when analyzing the results of the Security Optimization, as well as when determining and implementing the appropriate measures, contact SAP's Security Consulting Team for on-site consulting via SecurityCheck@sap.com. How to review the effectiveness of the implemented measures To prove the effectiveness of the implemented measures, you can request an additional complete SAP Security Optimization check. If you are supported by SAP Consulting during the implementation, our security consultants can perform individual checks to prove the effectiveness on-site. How to obtain additional security-related information Recommendations and guidelines concerning the security of SAP systems are included in the SAP Security Guide. This guide consists of three separate volumes, each with different levels of detail. Volume I provides an overview of SAP's security services. Volume II describes the services in detail. Volume III contains security checklists. For more information about these guides, see the SAP Service Marketplace at For additional security-related information, see the SAP Service Marketplace at Concluding remark SAP Security Optimization provides only a snapshot of the effectiveness of the implemented security measures. Over time, however, every system faces changes that might impact your overall system security. We therefore recommend that you run SAP Security Optimization at regular intervals. 4 Detected Issues The following list gives you an overview of all checks in the SAP Security Optimization service that are rated with a high risk: Action Items *** Special Focus Checks *** 5 Users - Other Than the System Administrators - Are Allowed to Call ST14?

First, read the complete report, and then decide for each check whether it is advisable for you to change the current situation. Sometimes you will find out that your current situation is sufficient, even if checks are rated with a medium or even high risk. Since every SAP implementation is different, you have to adjust this general report to your particular situation. 5 Special Focus Checks 5.1 Additional Super User Accounts Found (0022) In this system, the following superuser accounts were found that were not mentioned in the questionnaire. (These are the users having the profile SAP_ALL). All superuser accounts that were found in your system are REMOVED from all the following checks. This means that checks that report 5 authorized users, for example, actually have 5 users and ALL superuser accounts authorized for your system. Keep this in mind when you look at all other checks below. 000 DDIC A SUPER 000 SAP* A SUPER 000 Count : DDIC A DDIC ddic SUPER 001 SAP* A SUPER 001 Count : 0002 Use the Profile Generator (transaction PFCG) to correct roles and transactions. Use transaction SU02 (Maintain Profiles) or transaction SU03 (Maintain Authorizations) to correct profiles and authorizations, depending on your environment. You can use the authorization information system (SUIM) to check the results. For this check, we recommend that you examine the roles or profiles that include the authorization objects listed below. 5.2 Users - Other Than the System Administrators - Are Allowed to Call ST14? (0168) The download for the SAP Security Optimization can be viewed by any user who has authorization for transaction ST14. For this reason, this authorization is very critical and should only be given to very limited users. The SAP Security Optimization data is sensitive, it contains the current security situation for your SAP system. If this information falls in the wrong hands, there is a potential for major security issues. SAP Security Optimization Self-Service, <Date> 10

11 Use the Profile Generator (transaction PFCG) to correct roles and transactions. Use transaction SU02 (Maintain Profiles) or transaction SU03 (Maintain Authorizations) to correct profiles and authorizations, depending on your environment. You can use the authorization information system (SUIM) to check the results. For this check, we recommend that you examine the roles or profiles that include the authorization objects listed below. Object 1: S_TCODE with TCD=ST14 [and all relevant parameter transactions] SAP Security Optimization Self-Service, <Date> 11

12 6 Authentication 6.1 Passwords Password Logon Is at Least Partly Allowed (0139) Logging on with passwords is at least partially allowed. Allow all users to log on with their password (login/disable_password_logon = 0), or at least special groups that are described in the parameter login/password_logon_usergroup. If you are not using Single Sign-On (SSO), at least think about implementing an SSO solution. To further increase the security of your systems, prevent users from logging on with their passwords Users - Other Than User Administrators - Are Authorized to Change Passwords (0121) The following users are allowed to change and reset passwords. This is very risky because all these users could change the password and log on themselves with any user. The only consequence is that the "real user" would no longer be able to log on, because the password has been changed. This results in the password being reset because there is a chance that the "real user" might think they have forgotten the correct password. Use the Profile Generator (transaction PFCG) to correct roles and transactions. Use transaction SU02 (Maintain Profiles) or transaction SU03 (Maintain Authorizations) to correct profiles and authorizations, depending on your environment. You can use the authorization information system (SUIM) to check the results. For this check, we recommend that you examine the roles or profiles that include the authorization objects listed below. Authorization Objects: Object 1: S_TCODE with TCD=SU01 or TCD=OIBB or TCD=OOUS or TCD=OPF0 or TCD=OPJ0 or TCD=OVZ5 [as well as all relevant parameter transactions] Object 2: S_USER_GRP with ACTVT= Interval for Logon with Initial Password Is Too Long (0123) PARAMETER: LOGIN/PASSWORD_MAX_IDLE_INITIAL Rating Instance Current Value Recommended Value All instances 0 7 As of SAP NetWeaver 6.40, SAP supports this parameter to encourage your users to create more secure passwords. Activate profile parameter login/password_max_idle_initial, and set it to a value between 1 and 7. This parameter specifies the maximum period for which an initial password (a password chosen by the administrator) remains valid if it is not used. After this period has expired, the password can no longer be used for authentication. SAP Security Optimization Self-Service, <Date> 12

13 6.1.4 Interval for Logon with Productive Password Is Too Long PARAMETER: LOGIN/PASSWORD_MAX_IDLE_PRODUCTIVE Rating Instance Current Value Recommended Value All instances 0 > 0 As of SAP NetWeaver 6.40, SAP supports this parameter to encourage your users to create more secure passwords. Activate profile parameter login/password_max_idle_productive. This parameter specifies the maximum period for which a productive password (a password chosen by the user) remains valid if it is not used. After this period has expired, the password can no longer be used for authentication Interval for Logon with Reset Password Is Too Long (0124) PARAMETER: LOGIN/PASSWORD_MAX_RESET_VALID Rating Instance Current Value Recommended Value All instances 7 As of SAP Web AS 6.40, SAP supports this new parameter to encourage your users to create more secure passwords. Activate the new profile parameter login/password_max_reset_valid, and set it to a value between 1 and Trivial Passwords Are Not Sufficiently Prohibited (0125) Parameters Description Current value Default Value USR40 Entries Number of entries in USR You already use entries in table USR40. They can be used on a generic level as well.

Activate the new profile parameter login/min_password_specials and set its value to at least '1'. 6.2 General Authentication Security Critical Events for End Users Are Not Logged in the Security Audit Log (0136) Client Logging 000 Deactivated 001 Deactivated SAP Security Optimization Self-Service, <Date> 14

15 Use transaction SM19 to activate logging of failed logon attempts for all your users in all clients. It is then possible to find out who performed which action, and how to detect an unauthorized logon attempt Interval After Which Inactive Users Are Logged Off Is Too Long (0137) PARAMETER: RDISP/GUI_AUTO_LOGOUT Rating Instance Current Value Recommended Value All instances If you deactivate this parameter by setting it to '0' or if you use a value higher than 1 hour, it is likely that users who are no longer in the office remain logged on. If you do not use screen savers at all workstations, this could result in other users accessing these workstations to get to unauthorized information.
