Secure your data in cloud


Last year several cyber-attacks were observed that caused global disruptions to businesses worldwide. These attacks also led to financial losses and caused harm to organization’s repute. All the past cyber-attack incidences along with the evolutions in them today, focuses on the need for enterprises to consider security to protect the data- which is their most valuable asset.

In order to create effective defense, enterprises must understand, strategize and plan for the risks that are present in the organization. In case of succeeding in the cloud, enterprises must know their data that helps a company to identify sensitive data and remove data that shouldn’t be stored on cloud. It is a good practice for businesses to know the value of their data in the cloud, as that information can be used to better plan their cyber security policies. This drives a method behind building a data management strategy which is robust in order to keep data safe and protected even in complex cyber threat environment.

To maintain control of enterprises data and achieve compliance, following are the steps you should pursue for securing data in cloud environments:

1.      Controlled access to applications based on cloud

Like other enterprises, you also want to take benefit of cloud-based Software-as-a-Service (SaaS) applications, such as Amazon Web Services, Salesforce and MS Office 365, in order to support employee mobility and for the seamless scalability of resources to meet growing business needs. You can’t afford to lose confidential data of your business to unauthorized users. Adopting well-built multi-factor authentication methods will ensure only approved set of users can access company’s cloud-based apps.

2.      Encrypt sensitive data wherever it is sent

In cryptography, (cryptography is all about constructing & analyzing protocols that prevent the public from reading private messages in a communication) encryption refers to the method of encoding information in a way that only approved parties can access it and the un-authorized cannot access them.

If your industry finds more value in data today than ever before, if you also know that more data is generated, processed & stored on cloud. You should know that it is more prone to become a prime target for attackers. Encryption would act like a data shield for all your data and it will apply security and access controls directly on your data wherever it resides, even if it moves through the enterprise’s cloud, on-premises, hybrid and virtual cloud environments.

3.      Own, manage, and secure encryption keys

When you have your enterprise’s confidential data encrypted, it may happen that your team might need a new technique to manage & store the encryption keys used to protect the information sent across cloud, on-premises, hybrid and virtual environments. But you also want to make sure that the control of these encrypted keys stays with you only and not with a cloud services provider, for that matter not even with any 3rd party vendor.
A device called Tamper-Resistant Security Module (TRSM) is a hardware module that provides an extra level of protection to the encrypted key storage and all the cryptographic actions. The TRSM also integrates physical protections to avoid compromise of Cryptographic Security Parameters (CSP). So with this method central monitoring and management of encrypted keys can be achieved and data in the cloud can be handled by you.

Security now a day is the most essential parameter in cloud-based services & deployments and by building in the strong security capabilities described in above steps, organizations can manage & protect business data in a better way and the devices stored on the cloud.

The Past, Present and Future of Cloud Computing






Did you know the concept of sharing computing resources has been around since the era of mainframe computing which began in the 1950s and the term “cloud computing”, which is comparatively a modern term, was coined only in the last 10 years and back users were concurrently able to access and share a central system through various computers. It was realized by enterprises that since purchasing and maintaining computing capacity was so expensive, it made sense to share the resources for economical reasons. This is when the idea of sharing computing resources aka cloud computing came into picture. The concept of virtualization leads the way in the 1970s where several virtual computers ran on a single hardware, but this idea did not catch up early.

The very first milestone in cloud computing history took place in 1999 after the arrival of salesforce.com, which lead the way of delivering business applications through a website. This initiative by salesforce paved a way for specialist as well as mainstream software corporations to deliver apps on the internet. Soon after salesforce, Amazon came into picture and started working with cloud computing technology starting with AWS and launching their Elastic Compute Cloud (EC2).

Later on Google and Apple too adopted cloud technology which marked another major milestone and since then the cloud has been growing and evolving at a rapid rate. Then around 2005, businesses realized that it made more economic sense to buy shared computing resources from the cloud since it required lesser man hours and efforts and in turn had more capabilities and was inexpensive.

Cloud computing as a technology has existed for quite a long time now and the way enterprises have used it has been rapidly changing. It began as a simple hosting service and has evolved to IaaS, PaaS and SaaS. Looking at the present day scenario, large scale cloud computing is now accessible to everyone. It’s not just limited to big players in the market and now is open to anybody, anywhere. Cloud has now grown into a well-known approach for the management & deployment of applications for growing number of businesses.

Looking into the future, according to computer giant IBM, 2.5 billion gigabytes of data was generated every day in 2012. This data was generated by various industry verticals and consumers. For example, approximately 120 hours of videos are uploaded to YouTube every minute and about 200 million e-mails are exchanged every minute. A report, called ‘State of the Cloud Computing by Byron Deeter’, showed that the cloud computing market is growing at a 22.8% and the compound annual growth rate will reach $127.5 bn in 2018.

We live in a world where we are surrounded by a lot of gadgets and also, the number of IoT devices are growing as well. We now not only access information but we consume it to make decisions in real-time. This enormous size of data generated will also need to be collected together and processed in the Cloud. So, very soon cloud computing technology will allow us to work faster with more efficiency than it is today. In addition, together with their spread, our life will accelerate.
