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
SCADA Cyber Security Vulnerability Assessment
A U.S. power company employed regularly-recurring audits of various controls, systems and programs. However, when it came to a SCADA-based cyber security vulnerability assessment, the in-house audit team did not possess the specific combination of process control experience and cyber security risks. They realized they required a third-party expert with a unique combination of knowledge of the two worlds.
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
Arkessa | Enabling IoT Security
The assumption of trust which accompanied the early days of the internet is gone and replaced by privacy and security concerns accompanied with attitudes to risk which rise and fall across different sector and application scenarios. IoT covers a diverse range of services and products deployed in both managed and unmanaged use-cases with varying network topologies which bring different security challenges and new potential for attack.
