OPERATIONS have the required patches available . Equipment replacements in the IT industry are frequent and simple . It is not the same in the OT world , as some equipment will only work on an old operating system , and in many cases , continuing to use it is the only option when it comes to crucial operations .

Third , conduct regular vulnerability assessments
