What is Cloud computing?
Cloud computing is a style of computing where scalable and elastic IT capabilities are provided as a service to many users to consume in a pay-per-use and self-service way. Users are provided with dynamically scalable and virtualized resources as a service over the internet.
Why choose Cloud computing?
Cloud computing is convenient and user-friendly. It offers benefits such as the ease of software maintenance. No CD is required to install the resources and users do not have to worry if their software is out of date. Servers and capacity planning are also not required with Cloud computing. It does not require any equipment outlay and you do not need to guard against obsolete hardware. Cloud computing applications can also be access anywhere on your computer or mobile. Redundancy and disaster planning is also taken care by your cloud provider. With all these benefits cloud computing has to offer, many businesses have started to use cloud computing today. However there is also bound to have disadvantages.
Cloud computing has been making its advances but the threats to this technology are more tangible than ever. It has to overcome various serious threats to maintain its credibility. Here is a list of threats face by Cloud computing:
• Data Breaches
• Data Loss
• Account Hijacking
• Insecure application programming interfaces
• Denial of Service
• Data Handling
Nature of Threat
Data Breaches
Computer systems are connected to the internet. This exposes cloud computing service providers to skilled hackers with malicious intentions. The computer systems can be accessed virtually by anyone. This hackers continue to grow and pose a threat to the users of cloud computing.

CipherCloud for box
The CipherCloud Gateway helps to scan all content which are uploaded to Box. It enhances security by having alerts, blocking, prevent sharing or other customizable security options. If a user uploads a file that has restricted data like a social security number which violates company policy, the file will be moved to a quarantine folder automatically. This policy action will be sent to the users and not allowed to access the file until the administrator authorized that it is safe to share.
Conclusion
With the advanced technology, along with the constantly new software that is in the market, it takes time to keep up-to-date with all the firmware and operating system. The solutions mention can never be dependable unless we stay vigilant and watch out for our own security to prevent attackers from gaining the upper hand.
The idea of accessing, storing, and processing data from online server or virtual server instead of local server is called as Cloud computing. When we store data in our hard disk which is very near to computer that is called as local storage and computing but Cloud computing doesn’t access data from our hard disk.
As its core essences cloud computing is nothing but a specialized form of grid computing and distributing computing’s which various in terms of infrastructure , deployment, service and Geographic’s dispersion (Veeramachanenin, Sepetember 2015) the cloud enhance scalability, collaboration, availability , ability to adapt to fluctuation according to demand accelerate development work and provide optional for cost reduction and through efficient and optimized computing. (BH kawljeet, June 2015) cloud computing (CC) recently become as a new paradigm for the delivery and hosting of services our the internet. There are mainly three service delivery model Software as Service (SaaS) required software, operating system and network is provided or we can say in SaaS the customer can access the hosted software instead of installing it in local computer and the user can access these software through local computer internet browser (e.g web enabled E-mail ) the user only pay and the cloud service provider is responsible for management or control of mobile cloud infrastructure some of the company which provide such service are Google, Microsoft , Salesforce ,Facebook, etc…..Infrastructure as Service(IaaS)the cloud provider only provide some hardware resources such as network and virtualization is
Cyberespionage in today’s world has become more than a farfetched conspiracy theory. The reality is that there are legitimate threats to individuals, corporations, and governments occurring daily with the purpose of gaining access to confidential information. It is imperative that everyone from end users to network administrators are aware of the threat that cyberespionage poses, and are familiar with methods to detect and prevent these types of attacks. Failure to do so can leave sensitive data vulnerable and victims dealing with the potentially damaging effects.
Cloud computing is defined by experts as a type of computing that relies on sharing computing resources rather than having local servers or personal devices to handle applications. The meaning behind the word cloud is that it is a metaphor for the entire online web and its data as well. A cloud service differs from traditional hosting in three different ways. These three differences are that cloud computing is elastic, it is sold on demand, and the service is managed by the provider of the cloud. The easiest way to explain what cloud computing does is that it stores and gives access to different data and programs over the internet rather than just your computer’s hard drive. For it to be actually considered cloud computing it must include data or programs over the internet. Cloud computing can be done anytime, anywhere with an online connection.
The most widespread and reigning operating system, Window XP that was released on October 25, 2001 and was considered to be the most outstandingly accepted operating system platform among Consumer and Business Markets is now after April 8, 2014 will be defunct. That means , starting from April 9,2014 Microsoft will no longer provide support, market or any updates, hot fixes, any type of support options like Microsoft Security Essentials or online technical content updates. Also, there can be the scenario when great number of apps and devices don’t even work well with Window XP. Now, this will increase the hacking attacks exponentially on machine that are still continued to use Window XP. This looming sunset will have direct impact on enterprise environments, security locks on doors/buildings, automated teller machines, government computing devices, E-Commerce, military computing devices, retail industry with POS and other application running in that environment and other organizations that deals with Credit Cardholder data and those who are obliged to comply with PCI DSS requirements.
...common risks and their mitigating techniques are: Unauthorized access to data centers, computer rooms, and wiring closets – this risk can be mitigated by applying policies, standards, procedures, and guidelines for staff and visitors to secure facilities. Servers must sometimes be shut down to perform maintenance – this can be mitigated by creating a system to tie servers, storage devices, and the network together and created redundancy to prevent down time on mission critical services. Server operating systems vulnerability – this can be mitigated by ensuring all server operating system environments are defined with the proper patches and updates. And lastly cloud computing virtual environments are not secure by default configurations – can be mitigated with setting up virtual firewalls and server segments on separate VLANs to help prevent failure in the network.
Cloud computing is computing in which large groups of remote servers are networked to allow the centralized data storage, and online access to computer services or resources. Clouds can be classified as public, private or hybrid
It would be very difficult to ignore the potential benefits of cloud computing, but it also brings a number of new and worrying risks. Following are typical control requirements or opportunities that businesses may need to consider when considering a move to the cloud
Cloud computing is able to increase the speed of business. Cloud computing offers the speed to make computing resources on an instance basis, not just need to first survey time and skilled resources in design and implement infrastructure and applications to deploy and test it. Cloud computing can engance revenue, share bigger market, or other advantages.
As more and more people go online around the world especially in third world countries, their sheer numbers pose a significant threat to global cyber security. Criminals will seek out these new online connections for botnets to attack IT systems globally. By the year 2020, two hundred billion devices will be connected to the internet, so cyber thieves will grow in numbers to access these
As electronic commerce, online business-to-business operations, and global connectivity have become vital components of a successful business strategy, enterprises have adopted security processes and practices to protect information assets. But if you look at today's computing environments, system security is a horrible game of numbers: there are currently over 9,223 publicly released vulnerabilities covering known security holes in a massive range of applications from popular Operating Systems through to obscure and relatively unknown web applications. [01] Over 300 new vulnerabilities are being discovered and released each month. Most companies work diligently to maintain an efficient, effective security policy, implementing the latest products and services to prevent fraud, vandalism, sabotage, and denial of service attacks. But the fact is you have to patch every hole of your system, but an attacker need find only one to get into your environment. Whilst many organisations subscribe to major vendor's security alerts, these are just the tip of the security iceberg and even these are often ignored. For example, the patch for the Code Red worm was available some weeks before the worm was released. [02]
43% of cyber attacks target small businesses, and 49% of them are web-based attacks. More companies are using cloud networks to store their data. It's cheaper and easier to manage than a personal network. But it also makes companies more susceptible to cyber attacks. A trustworthy disaster recovery service implements private cloud hosting.
Cloud computing facilitates sharing of computing and storage resources with the aim of reducing computing expenses in organizations. Moreover, cloud computing facilitates information sharing among individuals within a cloud. Despite being advantageous, data stored in a cloud is usually prone to hacking and other security issues. This paper addresses the various mitigation measures that organizations are using to ensure that data stored in the cloud is secure.
Cloud storage basic terms, is a way to save information to the web that can managed data storage. Cloud computing services are online services, which store this information to a safe and secure location online. It’s offered a quicker, easier and safer backup than conventional methods of file storage such as bookshelves or cardboard files.
In cloud computing, the word cloud is used as a metaphor for “the internet”. So the cloud computing means “a type of internet-based computing”, where different services such as servers, storage and applications are delivered to an organization’s computers and devices through the internet.
