Do you think cloud is safer than traditional datacenter: An overview

Cloud computing is a synonymy for distributed computing over a network and ‘Yes it is safer than traditional datacenter’. Cloud Data Center intends to run programs or applications on a lot of connected devices at the same time. It is achieving popularity because of excellent points: Infrastructure flexibility, faster deployment of data, cost control, improved productivity etc., but there are still questions in the mind of customers:

‘How deep is the security customization? Will my data be encrypted? What is the status of physical security of the servers/storage solid? What protection is provided if there is a security breach?’

Now these questions are raised only due to the Security Concerns on Cloud Computing. And these security questions of customers are answered by Cloud Computing by using the best-practice of multi-layered security and some other excellent ways to secure data mentioned below:

1. Firewall: It sits at ‘Access Point’ of the network and performs rudimentary check to control data and services access.

2. Access to resources is located within their clouds and they are given rights to manage only those resources. Therefore, the cloud customers are provided with Management Portal that is encrypted to manage their resources. SSL Encryption is the best tool used for this task.

3. In Cloud Datacenter the customers are rendered with a transparent and  secure backup mechanism which allows them to take back up on consistent basis and enable quick restoration at downtime.

4. Snapshot and cloning capabilities of Cloud Computing Technology has made this possible to backup and restore data, this has also provided a potential to use complete operating system and applications on other operating systems present on cloud.

5. In Cloud Computing the authentication of system users and administrators in such a way that so that a track could be of footsteps is recorded by knowing who is doing what within the system, when they did it and what exactly they did. In Cloud Computing any access to cloud resources either by the customers/system users/ administrators is logged for auditing purpose.

6. Data Encryption adds an extra layer of protection, even if the whole system is compromised. Encrypted Data when traverses the network, it is much more difficult for the attackers to do any harm with intercepted traffic.

Now when we discussed the same with QA Testing folks working on Cloud testing we got some mixed reaction. While one said that:

“Cloud computing technology has just gained visibility in the recent years and due to its short period in the market it is difficult to compare with Traditional Data Centers. In this era, where everyone is running after the storage of their digital property on cloud. This not only saves the data against crashes but also aims at saving a lot of money that may be spent on the hardware/infrastructure. But the question still remains, how safe is the data on the cloud. With no laws made to guide the security policies of the web, the data that is present on the cloud can be easily accessed by anyone. The various security issues can be:

1. Privacy-is your data being mined for various market researches and advertisements?

2.  Reliability- being sure of the availability of data whenever needed;

3. Security- is your data encrypted? If yes, who all have the access to the encryption key?

4. Copyright- who owns the content that you upload, can anyone sell your content without your permission.

And if we go on making a list, we can jot down many such issues. The data being not secure on the cloud can be made clear with the recent revealing of PRISM national security surveillance program, run by the United States National Security Agency (NSA).

With the revelations made by Edward Snowden it has become evident that the NSA is spying on every user by directly accessing their data on cloud services and applications such as Google, Amazon, and Facebook etc. Similarly hackers can also access the data by hacking into the Cloud

Hence, it can be rightly said that, with the present structure of the laws, the traditional datacenter is much more secure in terms of safety than cloud”.

However, when we asked one of the QA testing manager working on Cloud testing had a different view point as he said:

“Yes, the cloud is safer than traditional datacenters, our common knowledge says that it is very important that the data which needs to remain secure should be kept in the data center. But the fact is that the data kept in the public cloud can be more secure. There are various factors which contribute to the cloud being safer.

In case of development lifecycles, cloud is more secure since the security practices are planned and built in. And development can be done from scratch with the best security.

For every organization, there are threats that an internal person who has access to the sensitive data can access it for wrong purpose, but in a large cloud operation this threat is very limited and thus because of stricter access controls the security is not compromised.

The cloud providers need to store a very high amount of data which requires a high level of expertise which is not available in-house and this high level of expertise ensures more security.

Apart from the security testing, the cloud provider makes sure that there is regular monitoring and auditing. This helps to spot an intrusion attempt immediately. Also, it helps to make sure that latest versions of software are being used.

Next comes the controlled environment since the hardware, software etc. are standard. The controlled environment is more secure. So, when new systems are implemented automation principles are used which leaves no chance for a security lapse. Thus the cloud is safer than traditional datacenter”.

Summary:

Cloud computing technology has just gained visibility in the recent years and due to its short period in the market it is difficult to compare with Traditional Data Centers. In this era, where everyone is running after the storage of their digital property on cloud. This not only saves the data against crashes but also aims at saving a lot of money.

Cloud Computing Security – Why It is Important?

Since invention, cloud computing is getting changed in all the way, and now became a crucial application that world uses to interact with and manage data. With all these developments, users are very much concerned about its security as well. Companies, non-profit organizations, education programs, and individuals are started using cloud computing for different internet requirements, but everyone has question in the mind that whether the application is secure enough for handling sensitive data. Well, the answer is ‘Yes’.

Cloud computing is as secure as a standard computing and hosting application. However, users sometimes feel that it is not secure because of the bad impressions arisen by the media.

It is true that cloud computing involves certain risks and this is why many providers give much importance for cloud computing security. Their schemes and physical security on site will be much tighter than old hosting platforms, wherein workers dedicatedly monitored how the network is working, and took action when intrusions detected.

The way how cloud computing has become a boon for society; simultaneously cloud computing security is much tighter for the network due to its security redundancy. Providers offer certain kind of encryption for the data so that when it enters to the server, it becomes impossible for outsiders to access.

The cloud computing and conventional computing differs in terms of nightly backups. It means, when something occurs, the latest backup is given from the night before while cloud computing offers backup after each transaction, quickly. Thus, a single fix quickly alleviates the issues inside the cloud. So, users don’t need to worry about the security of their data; cloud computing offers measures that ensure that their data is safe.

Though there are many hosts offering own kind of data encryption to help secure it, it will be more beneficial if users could take their own security measures so that when something bad happens, they can access to their data instantly. Besides, they can run their own back-ups of the data and keep their data in hands even if the cloud network goes down.

It is expected that cloud computing would be the future of data storage online because it offers instant access to information under a big and redundant backups for when the crucial fail should take place. Cloud computing security measures that protect the data will become the most stringent and therefore, users don’t need to worry about the security of their data.

Amazon and Google use cloud services to handle their big networks, and Amazon’s A3 services is available to the public as well. Getting space on A3’s network is fairly cheap in terms of cloud storage and distribution. However, having users’ data shared across many servers does give rise to many worries.

But all those worries are being wiped out these days with latest backups facilities by cloud computing. So, make use of most reliable and popular backup services by cloud computing and protect your data and information at the best possible manner.

 

Online Backup – Knowing the Modalities

Online backup offers the convenience of accessing sensitive data remotely from any place without having to cumbersomely carry it along. During unforeseen and unprecedented disasters, the data will stay secure in the servers of backup provider and can be accessed at ease afterwards. Businesses can derive tremendous competitive advantage through data security.

a) To embark upon online backup, one needs to open an account with a reputed service provider like Mozy. It provides premium and free account setup facility to mitigate the vulnerability of your data. The free version offers 2GB of backup space. After registering with them, software is required to be downloaded and installed to sync your hard drive with their offsite servers. Their user interface will guide you through the process of picking and choosing the files to be backed up.

b) IDrive.com is another site that offers 2GB of free backup space. All one needs to do is to have their software installed and logged into and the world of protecting critical data is just two clicks away.

c) Adrive intends to sweep you off your feet with its revolutionary backup plan of 50GB for free. The security front is a little weak in this case.

d) Microsoft has eased the process of online backup through its Wondow Live’s Sky Drive which offers the users capability to store securely with strong password protection up to 25GB of data. The mode of operation is extremely simple and users can drag and drop files on the online folders just like normal computer operation. The user is just required to have a MSN or hotmail account.

e) The leading email service provider Gmail too has jumped into the scene with its drive that is also providing considerable online space. A single Google account for the user would suffice to avail this attractive space that can upload and secure his files in the drive or send files directly from Gmail to the drive.

The process is more or less same for other service providers. However, one should opt for a service that has a formidable reputation under its belt and has a list of satisfied top notch clients in its kitty. Online reviews can be extremely helpful in arriving at the right service. Data security is at stake and any free service can vanish from the market without any prior notice. One should invariably make a carbon copy of the files uploaded in two or more services to ensure the safety of files in the event of a disaster.

The internet should be regularly reviewed to see the latest trends in the online backup arena. As days will roll by, state of the art technologies will have greater influence on the market making the life easy for people desirous of accessing data remotely from online locations.
