Make a ransomware incident response strategy so that your IT security staff knows what to do in the case of a ransomware attack. Defining roles and communications to be shared during an assault should be part of the plan. A list of contacts, such as any partners or vendors who would need to be contacted, should also be included. Do you have a policy in place for “suspicious email”? If not, try establishing a policy that applies to the entire firm. This will assist staff in learning what to do if they receive an email they don’t recognise. It might be as simple as sending an email to the IT security staff.
