There is increasing attention by Control system vendors to enhance cyber security and operate better in corporate IT environments. This attention is good because cyber threats are not decreasing and, at the same time, corporate IT environments are becoming more protected. While governments have focused on cyber security for “critical infrastructure” industriesCONTROL ENGINEERING China版权所有, such as water, power, telecommunications, and transportation, cyber security also is important for all manufacturing industries.
Some control vendors are using an increasingly popular method of bundling anti-virus and spyware protection with their products. Vendors test the latest version of antivirus software and operating system patches against their software, reducing your need to test and validate security patches and updates. In most cases the operating system (OS) patches are the latest Microsoft patches released on “Patch Tuesday” and are available from the vendor within one or two weeks of the Microsoft release. This gives the vendor time to test all standard configurations. The vendors will then redistribute the patcheswww.cechina.cn, executablesCONTROL ENGINEERING China版权所有, and signature (.dat) files that have been successfully tested along with notices of patches or updates that should not be applied. Vendor redistributed patches may also include JAVA updatesCONTROL ENGINEERING China版权所有, browser updatesCONTROL ENGINEERING China版权所有, and Adobe updates if this software is used in their products.
Another cyber security feature that more vendors are offering is preconfigured OS configurations. These are configurations which have unneeded services removed, ports locked控制工程网版权所有, hardware disabled (such as DVD drives and USB ports configured for thumb drives), unneeded applications removed, and security settings preconfigured. These systems reduce the errors associated with the installation of software and configuration of the hundreds of options and services installed
