Protection of data against ransomware using Cloud Computing.

Ransomware:

Ransomware is one of the many cyber-attacks that take place daily on a large scale.

Ransomware is a type of malware that prevents or limits users from accessing their system, either by locking the system’s screen or by locking the users’ documents unless a ransom is paid.  More present day ransomware families, collectively classified as crypto-ransomware, encrypt certain documents on systems and forces users to pay the ransom through certain online payment methods to get a decrypt key.

Ransomware malware can be spread through malicious e-mail attachments, infected software apps, infected external storage devices and compromised websites. Once executed in the system, ransomware can either lock the computer screen or, in the case of crypto-ransomware, encrypt predetermined files.

One high-profile example is the “WannaCry worm”.

Other ransomware are Ransomware Locky and Ransomware Gibon discussed in our next posts.

Last year ransomware took the cloud computing industry by storm. A recent survey of 500 businesses revealed that nearly half were brought to a standstill by a ransomware attack within the last 12 months.

While cybercrime turns out to be progressively normal, organizations are, affectingly, well behind in securing themselves with software safeguards, training of employees to prevent hacks or even covering themselves with effective cyber-focused insurance policies.

How Cloud Computing provides security against ransomware?

Cloud helps security operations respond quicker to threats and focus on business risk as opposed to spending countless hours researching threats and trouble-shooting aging on premises systems,” Nick McQuire, vice president of enterprise research at CCS Insight told CNBC via email.

But the experts suggest that cloud computing may provide the security the organizations are looking for. The main motivation for going to the cloud originally was not security, but this can become a key factor in success for cloud computing companies.

The best defense against ransomware is to outwit attackers by not being vulnerable to their threats in the first place. This means backing up important data daily and having a disaster recovery failover plan in place so that even if the IT systems get locked, users won’t be forced to pay to see their data again.

While backups are valuable, they won’t really make a ransomware assault easy. If the systems are affected by ransomware, customers can restore information from a previous unaffected machine version backed up by their cloud service provider from a point in time before they were affected.

In any case, while information is accessible, a business may not be restored until the point when generation frameworks are clear of any ransomware effects.This is where cloud-based disaster recovery comes in. It empowers associations to failover generation to a cloud service provider in case of a ransomware attack and re-establish production systems within minutes or even seconds.

In order to protect organizations against this rising threat, it is imperative for business leaders to ensure that on-premise levels of security are available in the cloud.
