An Improved Purdue Enterprise Reference Architecture to Enhance Cybersecurity

The rise of the Industrial Internet has accelerated the integration of industrial enterprise networks and introduced the problem of cybersecurity while improving productivity. The traditional Purdue Enterprise Reference Architecture (PERA) has found it difficult to meet the cybersecurity requirements of industrial enterprises in the new situation. This paper investigates the history of PERA proposal and development, analyzes its cybersecurity problems, proposes an improved PERA to improve cybersecurity, realizes enterprise cybersecurity monitoring through the method of mirroring network traffic, constructs an independent cybersecurity monitoring zone to centralize the deployment of cybersecurity solutions, and constructs an enterprise security operation center, all of which can effectively improve the cybersecurity of enterprises.
