作者： Meysam Tahmasebi School of Technology and Innovation Marymount University Arlington USA

As cyber threats keep changing and business environments adapt, a comprehensive approach to disaster recovery involves more than just defensive measures. This research delves deep into the strategies required to respond to threats and anticipate and mitigate them proactively. Beginning with understanding the critical need for a layered defense and the intricacies of the attacker’s journey, the research offers insights into specialized defense techniques, emphasizing the importance of timely and strategic responses during incidents. Risk management is brought to the forefront, underscoring businesses’ need to adopt mature risk assessment practices and understand the potential risk impact areas. Additionally, the value of threat intelligence is explored, shedding light on the importance of active engagement within sharing communities and the vigilant observation of adversary motivations. “Beyond defense: Proactive Approaches to Disaster Recovery and Threat Intelligence in Modern Enterprises” is a comprehensive guide for organizations aiming to fortify their cybersecurity posture, marrying best practices in proactive and reactive measures in the ever-challenging digital realm.

The existing industrial control systems（ICS） security solutions cannot be directly used for secret or high sensitive areas,for lack of mature theory support and difficult engineering *** this paper,data shunt and one-way transmission security model based on defense-in-depth framework is put forward to ensure the production area availability as the primary *** key signals and instructions of production area are copied *** copy is used to production and the other one for cyber after photoelectric conversion device of isolation ***-way transmission,response speed;data accuracy and product procurement are *** results show that the circuit characteristics of one-way information transmission can prevent outside attack based on general industry *** model has no influence on the transmission of the signals and instructions of production *** time delay and the loss of data accuracy caused by model meet the actual *** components of mode are general and easy to purchase and be used in the practical *** model can be extended to test various emerging ICS security solutions based on defense-in-depth.
