The number of cyber attacks on industrial control systems has been increasing and the activity is visible on a global scale by site, manufacturer, and even by actual control system specific parameters. Many of those attacks are possible because of vulnerabilities in operating systems and applications, which need to be fixed using software patches. Having a sound patch management program in place will greatly reduce your risk and make you a hard target to a would-be attacker. That sounds good, but what does it mean? What exactly is patching? According to dictionary.com, patch, in verb form means to mend, cover, or strengthen with or as if with a patch or patches. It’s also a noun, meaning a piece of material used to cover or protect a wound, an injured part, etc. |
