Faulty ERP integration with a distributed application architecture is the fastest route to costly downtime, ransomware attacks, and loss of customer trust. Effective ERP integration security requires going beyond standard protocols and implementing precise access controls and encryption for data in transit. Learn how to conduct a professional ERP security audit and use our ready-made framework to eliminate vulnerabilities in your company’s IT ecosystem.Challenges of integrating ERP with different systems
Although there are many
arguments in favor of implementing an ERP system in the workplace—including lower operating costs, greater efficiency, and standardized processes on a single platform—it is important to recognize that integrating ERP with other systems used by the company can be challenging. One of the main reasons is the complexity and diversity of the technologies involved. Differences in architecture and functionality, as well as the complexity of the business processes themselves, can lead to incompatibility between systems. The lack of uniform communication standards and integration protocols can also be a problem because it directly affects data exchange. It is also worth remembering that the data itself can create many difficulties: it may be incomplete or inconsistent, making its transformation time-consuming and labor-intensive. Nontechnical challenges must not be overlooked either. Integrating technologies with an ERP system may require significant financial investment at every stage, and the process itself can take months. Such a lengthy integration may have many causes. While technological problems can be relatively easy to solve, cultural and organizational issues may require much more work. Implementing an ERP system often meets with resistance from employees. This is hardly surprising: fear of losing one’s job to automation is entirely natural. Therefore, in addition to
choosing an ERP system suited to their specific needs, organizations taking this step should devote time and resources to end-user training. After all, the better employees use the system’s capabilities, the greater the benefits for the entire organization.
Risks and consequences of insecure integration
The security of ERP integration with other systems deserves separate consideration, as the process may expose vulnerabilities that can be exploited to attack an organization. The most fundamental problem in this area is data breaches: unsecured integrations can lead to the theft of confidential information. The disclosure of sensitive data is one of the worst situations any company can face. Whether it results from theft by hackers or employee error, it invariably causes reputational damage and financial losses. Ransomware attacks are another ERP integration risk. They are particularly likely when integration is carried out incorrectly or without appropriate security standards. In such a situation, the company risks not only losing access to its software, but also operational downtime and financial losses. It is also possible that inadequate integration security could result in unauthorized changes to data or, worse, fraudulent financial transactions. It is worth remembering that any vulnerability in the integration between a company’s software and its ERP system may result in unauthorized access and, consequently, data theft. Remediating security breaches can also be costly, and the technical and legal expenses may far exceed the cost of the integration itself.
Strategies for preventing security vulnerabilities during integration
How, then, can you secure ERP integration? Fortunately, there are many methods, and they cover the system as a whole. A good place to start is ensuring that the architecture is properly protected: divide the network into segments and place publicly accessible servers in demilitarized zones, isolating them from the intranet and thereby increasing the security of the entire environment. Access control should be addressed at the same time. The absolute minimum is to apply the principle of least privilege and require users to use two-factor authentication. This can—and should—be combined with encrypting data both in transit and at rest. These measures are especially important as
ERP systems become increasingly integrated with the Internet of Things. Hackers may, for example, exploit vulnerabilities in smart sensors to gain access to the system. Another effective strategy for improving ERP integration security is to use secure APIs and only the interfaces and services that are necessary; the latter reduces the attack surface. In addition to these methods, it is worth investing time in prevention. Regular security audits and penetration testing can work wonders. Combined with regular software updates, employee training, and cooperation with vendors on technology security, they can make an ERP system resistant to almost all attacks.
Integration security audit: steps to follow
When integrating company software with an ERP system, it is worth asking:
how can ERP implementation costs be minimized? There is no denying that these costs can be substantial, especially when implementation covers many departments, so it is important to maintain an appropriate cost-benefit balance. In this case, the answer is simple: because security breaches increase costs and integration can expose numerous vulnerabilities, expenses can be reduced by conducting a thorough security audit. But how should such an audit be performed? First, identify the systems, processes, and interfaces to be assessed. This makes it possible to define the audit objectives—for example, identifying weaknesses in integration security. Every software component should then be reviewed with the selected objective in mind. The next step is to analyze potential threats. This involves not only determining which attacks could result from specific deficiencies, but also defining their consequences for the organization and the likelihood of their occurrence. This analysis provides the basis for assessing existing policies and procedures and helps identify any gaps in them. Specific system and tool configurations can then be checked and reviewed for irregularities. Both penetration and performance tests can be used for this purpose. Technical and operational documentation must also be reviewed, with particular emphasis on event-log analysis. Once this work is complete, a report should be prepared. It should include detailed descriptions of the problems found, their causes, and recommendations for remediation. The issues requiring the most urgent action should also be prioritized; after that, all that remains is to monitor progress on the assigned tasks. It is a good idea to repeat the audit periodically—for example, quarterly—so that the ERP system remains protected against attacks.
