How Secure is Your Data on Cloud?

Cloud computing has been a boon to today’s IT world as it has helped different categories of business soar high. Let it be IT, pharma, banking or operations, cloud computing has reached its height everywhere turning the existence of bespoke applications a tiny one. Hosting your system is no more a challenge these days due to different levels of computing like Software as Service (SaaS), Platform as Service (PaaS) , Infrastructure as Service (IaaS) and Storage as Service (StaS) and deployment models (private, public, hybrid and community). What makes the tale more interesting is the security mechanisms cloud services offers to its clients. Cloud security is tackled in 2 ways

  1. Concerns of the customers hosting their applications and data on the cloud
  2. Concerns of the cloud service providers offering IaaS, PaaS and SaaS services.

In most of the cases the responsibility is Dual. The customers ensure all security measures including strong passwords and secure authentication measures. The service providers have implemented security at all levels in the Datacenter right from Physical to firewalls to application and data security.. while the responsibility lies with both the penalties on the service providers for Data leakage are quite high.

Data and Cloud

Data security Vs cloud computing is always been a debate these days. When moving data to the cloud, you trust your third-party data center to keep all the data intact and confidential. Any intellectual property data, confidentiality bound data are expected to be maintained securely and should be shielded from theft. There are different kind of issues that are faced both by the cloud providers and the customers who host their applications on the cloud. It should be kept in mind that traditional approaches of application development offer a stronger security mechanism making bespoke a protected one. However, when it comes to maintenance and support, cloud offers a cushion to its clients in creating a comfortable support model. Shared resources in terms of servers and storage are venerable for data leakages if adequate measures to secure the data are not implemented.  

Securing Data in Cloud

With the implementation of General Data Protection Regulation GDPR and other data regulation activities, cloud computing has become an even better platform for hosting applications. Let us look at some of the crucial data security mechanisms that are being adopted in cloud computing world.

  1. Encryption Mechanism –Adopting encryption mechanism is no more an old book story when it comes to the cloud. Strong encryption technology is the safest approach to deal with threats, data loss and confidentiality. Plain text is the extreme form of vulnerability, which puts your data at stake. However, by adopting the means of cyphertext and standardized algorithms, threats can be reduced. These encryption mechanisms are inculcated mainly for storage and transmission.
  2. Data Remanence – Carry forwarding the data throughout the cycle of its life is challenging. What is even more challenging is to securely delete the data at the end of its life cycle. This residual data that remain even after the multiple erasing strategy leads to data remanence. Some of the counterattack mechanisms that leading cloud providers offer are Destruction, Purging and Sanitization
  3. Hashing – One of the popular way of protecting the data against malevolent threats is hashing. Though hashing is mainly used when there is a need for one way and non-reversible protection mechanism, this kind of security is provided when mainly storing passwords. Hashing has the capability to easily digest the messages that are altered by malicious service agents where these messages will be rejected when the digest does not match.
  4. Penetration and Vulnerability testing on cloud. To keep a constant check on probable security breaches Cloud providers and customers do a scanning. This also checks the basic implementation techniques of hard portioning of virtual server’s data leak checks and virus attacks. This activity is done by agreement of both parties i.e Cloud providers and customers.

Apart from the above-mentioned mechanisms, some other popular ones include advanced firewall options, event logging, Identity and access management etc.

How Secure is Data in Cloud?

By offering a high range of security options, cloud revolution is witnessing a drastic change in turning the organization’s focus.Cloud privacy is highly dependent on the privacy mechanisms that is deployed in its platform. Thus, by choosing the suitable cloud provider for safeguarding your data, the chances of data intrusion are less and the benefit in turn becomes more.
