During cyberattacks, malicious actors bypass multiple security devices in order to achieve their goal: the application layer. Thus, critical data for daily business activities are often reached through applications and professional softwares like ERPs.
The various technologies used in ERP environments generate an increasing complexity for the management of patches and vulnerabilities, which makes protecting data more and more painstaking. This situation consequently degrades the cost / benefice ratio. Indeed, companies need to cover a large attack surface in order to protect themselves from hackers that can concentrate on just one precise vector to penetrate systems.
In order to minimize this attack surface, the security of systems & applications landscapes need to follow essential best practices:
