8 best practices to prevent ransomware

 

Back up your files

The most effective way to handle ransomware attacks is to use the 3-2-1 backup rule: keep at least three separate versions of data on two different storage types with atleast one offsite.

 

Educate end users

Regularly train your employees on how to identify and avoid common ransomware pitfalls such as malvertisements, phishing emails, etc.

 

Patch vulnerabilities

Reduce the vulnerabilities in your operating systems, browsers, and other applications by regularly updating them.

 

Use an intrusion detection system

Cut off ransomware attacks in their early stages using continuous monitoring to detect signs of anomalous or malicious activity in real time.

 

Employ email filtering

Block malicious executables, spam, phishing emails, and other methods ransomware is known to use.

 

Whitelist applications

Add acceptable software to your whitelist and block unauthorized programs from running.

 

Provide the least amount of privilege possible

Use robust access management to restrict unwarranted access and reduce the number of access points through which malware can enter your organization.

 

Logically separate networks

Mitigate data loss in the event of a ransomware attack by separating your networks according to task or department.
