JSE Virus
Hello,
Two of our network drive (server 2008 R2) has been encrypted by a crypto virus. all exel files have now the JSE extension.
we have restored the files but we are afraid of having this situation again
Can you advice us on how to avoid .jse files?

Security
Security is the protection of information systems from theft or damage to the hardware, the software, and the information on them, as well as from disruption or misdirection of the services they provide. The main goal of security is protecting assets, and an asset is anything of value and worthy of protection. Information Security is a discipline of protecting information assets from threats through safeguards to achieve the objectives of confidentiality, integrity, and availability or CIA for short. On the other hand, disclosure, alteration, and disruption (DAD) compromise the security objectives.
