ERP security- Enterprise resource planning (ERP) systems are an indispensable tool for most businesses. They allow them to track business resources and commitments in real time and to manage day-to-day business processes (e.g., procurement, project management, manufacturing, supply chain, human resources, sales, accounting, etc.).
The various applications integrated in ERP systems collect, store, manage, and interpret sensitive data from the many business activities, which allows organizations to improve their efficiency in the long run.
Needless to say, the security of such a crucial system and all the data it stores should be paramount for every organization.
Common misconceptions about ERP security
“Since ERP systems have a lot of moving parts, one of the biggest misconceptions is that the built-in security is enough. In reality, while you may not have given access to your company’s HR data to a technologist on your team, they may still be able to access the underlying database that stores this data,” Mike Rulf, CTO of Americas Region, Syntax, told Help Net Security.
“Another misconception is that your ERP system’s access security is robust enough that you can allow people to access their ERP from the internet.”
In actual fact, the technical complexity of ERP systems means that security researchers are constantly finding vulnerabilities in them, and businesses that make them internet-facing and don’t think through or prioritize protecting them create risks that they may not be aware of.
When securing your ERP systems you must think through all the different ways someone could potentially access sensitive data and deploy business policies and controls that address these potential vulnerabilities, Rulf says. Patching security flaws is extremely important, as it ensures a safe environment for company data.
Advice for CISOs
While patching is necessary, it’s true that business leaders can’t disrupt day-to-day business activity for every new patch.
“Businesses need some way to mitigate any threats between when patches are released and when they can be fully tested and deployed. An application firewall can act as a buffer to allow a secure way to access your proprietary technology and information during this gap. Additionally, an application firewall allows you to separate security and compliance management from ERP system management enabling the checks and balances required by most audit standards,” he advises.
He also urges CISOs to integrate the login process with their corporate directory service such as Active Directory, so they don’t have to remember to turn off an employee’s credentials in multiple systems when they leave the company.
