2- Intrusion Detection Technologies and Monitor Them
Intrusion detection systems or technologies monitor network traffic exploring for suspicious activity and identified threats, sending up alarms when it detects such things. These tools help organizations to detect the class of traffic anomalies that might imply that the organisation is breached. Also, monitor these technologies to see if they are working correctly or stopping ransomware. Use email security gap analysis tools to test your email protection or email security technologies are working or not.

Email filtering and Content Scanning technologies help to block unwanted or potentially-malicious code or links that redirect the user to malicious websites. These tools include both inbound email filtering and monitoring the outbound email traffic and the emails are categorized into different classes to identify them harmless. These tools are the most effortless way to stop workers from clicking on a ransomware link within an email. It stops ransomware before reaching users’s inboxes.

5- Have a Recovery Plan
A recovery plan or disaster recovery plan (DRP) is an organised and written strategy that outlines how an organization can instantly continue its business following an incident. This plan intends to support an organization to hinder data loss and recover system functionality to continue to function in the aftermath of an incident. However, having a written plan is not sufficient, organisations have to test their plan if it is working or not.
