Securing Network against Ransomware
Posted on 2016-07-25
I want to ask for advice on how to protect the backups and user data from Ransomware.
last week 1 User's personal Laptop in our network was infected by ransomware which he got from yahoo business email, and i have to restore his files and folders using the previous version. All the data was on his laptop was encrypted by ransomware, i don't have backup because it was his personal laptop & also no network mapped drive on his Laptop. but all other desktop users in our network have Mapped network Drive to share data.
We have 2 QNAP's each with 16 TB of space, 1 QNAP is used for keeping the backup and user data and the other QNAP is exact replica of first QNAP.
Each user is given a Mapped network Drive to share the documents between each other. if 1 PC is infected with ransomware then it can infect the mapped drive and can encrypt all other data & PC backups on QNAP.
We have McAfee Endpoint Protection 10 & acronis for backup on each PC. Mcafee doesn't detect the ransomware. how can we protect our network against Ransomware ? please advise...
