网络安全
概述
网络安全是指保护硬件、软件和数据不因意外或恶意原因被破坏、更改或泄露，以确保系统连续运行和网络服务不中断的保护措施。一种有效的网络安全方法具有跨计算机、网络、程序和数据的多层次保护，人们打算保持安全。为了有效防御网络攻击，任何组织中的人员、流程和技术都应该相互补充。网络安全可以分为物理安全和逻辑安全。物理安全是指对系统设备和相关设施的物理保护，使其免受损坏和丢失。逻辑安全包括信息的完整性、机密性和可用性。

Case Study
Driving Digital Transformation: Mazak Corporation
Mazak required a common, standards-based method to securely connect and derive value from the rich, raw data in its machine tools. An advanced security system suitable for IT and operations technology (OT) was necessary to protect from both internal and external attackers. The application needed to run on the network infrastructure on the factory floor, immediately transforming process, overall equipment effectiveness (OEE), and sensor data. The fog application needed to support the MTConnect specification for integration with existing systems and sensors. Real-time analytics were required to process high frequency vibration, temperature, coolant, and sound inputs to inform operator action and drive business support systems.
Case Study
ALD Automotive
ALD Automotive's rapid growth in 39 countries has led to an exponential increase in IT infrastructure complexity. In order to provide cost effective and high performance access when needed, a mix of local and central Internet connectivity has been established rather than backhauling all traffic to a central site. With the evolution of the Web, content has become more dynamic and threats more sophisticated. Secure hacks are encrypted and require SSL inspection. ALD Automotive was looking for a full complete security solution.
Case Study
IT Simplification to Improve the Healthcare Computing Environment
Increasingly sophisticated malware attacks can leave healthcare providers in a vulnerable position as they confront the critical need to improve security while also keeping IT costs under control. Concord Hospital has worked hard to cultivate a reputation for clinical and patient service excellence.As an example of its progressive approach to automating health service delivery, Hospitals & Health Networks magazine has named Concord one of the United States’ “Most Wired Hospitals” for several consecutive years. In order to maintain this level of operational excellence, Concord Hospital needed a solution to save time and resources while also improving results for software licensing, patch management, asset inventory and security configuration.
