One of the largest vendors of ERP and enterprise applications, SAP, through its system enables organizations to run their business processes including production, sales, accounting, payment, and several others in an integrated environment. However, several ERP systems are too complex with a diverse set of stakeholders throughout the enterprise. It is also possible that these systems have been in place since years and have made ERP security difficult and expensive to maintain. These could be some of the most important reasons which contribute to SAP vulnerabilities.
Though companies might hesitate to make changes in their production systems, it is important that all the systems have basic information security hygiene to avoid any security incidents. SearchSAP has a lot of resources for basic security controls of an SAP system including vulnerability management and patch management. Vulnerability management is implemented by regularly scanning applications, data and other related servers. The data is then fed into a patch management process to test and deploy.
A major concern has been the probability of downtime from security, for ongoing security controls. Plans should be made to apply patches or make security changes without disrupting enterprise operations. One such plan could be to ensure that a high-availability system, like a backup system, is in place to automatically take over at the time when the primary system is having changes made. Specific monitoring tools, like intrusion detection system could be deployed to monitor an SAP system. Also, monitoring SAP application logs is mandatory to detect any malicious activities at the application level. Utilizing least privilege concepts, like restricted network access, can reduce the chances for an attacker to gain access or attack other systems.
Excluding SAP systems in the information security program is what has led to the basic vulnerabilities still being present in SAP systems. Some of the above mentioned vulnerabilities have been known for years and the processes to fix them found outside SAP systems can drastically help improve security and also avoid severe incidents which could affect critical business operations.
