One step at a time: How to secure and harden your SAP Gateway

SAST SUITE: INTERFACE MANAGEMENTThe Gateway is a central communication component of an SAP system. As such, it is an attractive target for hacker attacks – and should receive corresponding protections. If the Gateway protections fall short, hacking it becomes child’s play. Despite this, system interfaces are often left out when securing IT systems. Should a cyberattack occur, this will give the perpetrators direct access to your sensitive SAP systems.

The State of SAP Security 2018: Between platform security, authorization management and S/4 HANA migration

SAST_HANA_S4HIt’s probably too early to sum up the state of SAP security in 2018.

It is at conferences and trade fairs like this that you get a chance to find out exactly what is on the minds of SAP customers. As a result, it isn’t too soon to get a reading of the security issues that are considered important in the SAP environment.

Are you really that attached to your ABAP security flaws, or is it time to say goodbye?

SAST Code Security AdvisorAlmost all companies fine-tune their SAP systems with custom developments, but in doing so, they often expose themselves to severe security flaws. In particular, forgotten code that was only needed for a short time or has since been rendered obsolete by SAP’s own enhancements presents a further avenue for attacks.

AKQUINET’s analyses show that up to 90% of ABAP code is no longer used. Frequently written for one-time situations and neglected ever since, such programming offers an ideal back door for hacking and other forms of manipulation.

SAST-Blog_Audit-vs-Pentest_Abb_1804To answer the question of which Security & Compliance check is right for you, we must first remember that the term “vulnerabilities” can refer to very different levels of your system landscape and thus refer to a number of attack vectors.

This ranges from system-side levels (e.g. operating system and network security) to the underlying database including the current parameterization of your SAP systems down to the authorizations required for operations and applications, including any SoD conflicts.

So, the first question is – how sure are you that you know where your vulnerabilities are? Continue reading

WITH HEADER LINE – it’s not simply obsolete; it’s a risk.

shutterstock_424352977_akqw_jpgThe addition “WITH HEADER LINE” has technically been unnecessary going back several SAP versions now. This is because the statement declares both internal tables and an additional data object – the header line.

There are a large number of notes that spread awareness that the use of this statement causes various content problems. Among other things, the use of the same name means that it is not immediately apparent as to whether you are working on a table or a header line.

However, what the notes typically do not warn you about is that this kind of programming goes hand in hand with security problems for your SAP systems.
