Data Breaches
Not just that it affects the 3 service models only, and not just high numbers on security risk matrix between perceived risk and actual risk, it also moved from position 5 in 2010 to position 1 in 2013[1]. According to “Top Threats Working Group, The Notorious Nine Cloud Computing Top Threats in 2013” It’s every CIO’s worst nightmare that the organization’s sensitive internal data falls into the hands of their competitors.
Cloud computing introduces significant new ways of attacks. In November 2012, researchers from the University of North Carolina, the University of Wisconsin and RSA Corporation released a paper describing how a virtual machine could use side channel timing information to extract private cryptographic keys being used in other virtual machines on the same physical server [2]. However, according to CSA [1] in many cases an attacker wouldn’t even need to go to such lengths. If a multitenant cloud service database is not properly designed, a flaw in one client’s application could allow an attacker access not only to that client’s data, but every other client’s data as well.
The study [1] shows that there are some Implications for data breaches. While data loss and data leakage are both serious threats to cloud computing, the measures to mitigate one of these threats can trigger the other. Encrypting the data may reduce the impact of a data breach, but losing the encryption key, means losing the data as well. Also, keeping offline backups of the data to reduce the impact of a catastrophic data loss, will increases the exposure to data breaches.

The reason why I chose to discuss the Target Breach because I’m currently a Target credit and debit Red Card cardholders. Although I was not affected by the security breach, I was very disappointed in how Target handled the situation. If I was one of the individuals that the breach happens to, I would like to be told of the breach right away, so I could have notified my bank, credit card companies, and put a warning of fraud to all three credit reporting agency.
In July 2015, many of the world’s high ranking cryptographers published that the loss and destruction induced by adopting a key escrow system 20 years ago would be even more serious, that would be very hard to identify security weaknesses that could be misused by
...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.
If organisation’s sensitive data and intellectual property resides on public cloud then it is strongly advisable to implement strong encryption techniques. The threat of data tampering is at its highest when data is being processed in the cloud. Essentially, this is because when data are
In this research paper, we will present you that In previous Decade side channel attacks show us that cryptographic Devices are vulnerable or we can say these devices can leak important information. In previous days cryptanalysis assumed that advance user can only has access to data pair which is to be input or output, has no knowledge of the internal state of Device. But today adversary can access the data by using spe...
In December 2013, Target was attacked by a cyber-attack due to a data breach. Target is a widely known retailer that has millions of consumers flocking every day to the retailer to partake in the stores wonders. The Target Data Breach is now known as the largest data breach/attack surpassing the TJX data breach in 2007. “The second-biggest attack struck TJX Companies, the parent company of TJMaxx and Marshall’s, which said in 2007 that about 45 million credit cards and debit cards had been compromised.” (Timberg, Yang, & Tsukayama, 2013) The data breach occurred to Target was a strong swift kick to the guts to not only the retailer/corporation, but to employees and consumers. The December 2013 data breach, exposed Target in a way that many would not expect to see and happen to any major retailer/corporation.
My knowledge has grown over the past six years, outwith the areas of learning offered by school courses, and I see this course as an opportunity to gain new skills and broaden my knowledge further. My main interests are varied, including communications and the internet, system analysis and design, software development, processors and low level machine studies. I have recently developed an interest in data encryption, hence my active participation in the RSA RC64 Secret-Key challenge, the latest international de-encryption contest from the RSA laboratories of America.
How would you like it if anyone could look at your text, contacts, searches, location. Apple even states “Intercept your messages, access your health records or financial data, track your location, or even access your phone’s microphone or camera without your knowledge.” This would all happen if Apple makes a back door to their iPhone. If Apple creates a “backdoor” to their iPhone. There will be consequences that could never be fixed in privacy and security.
The first computer ENIAC was invented by Charles Babbage in 18th century. But the real technological advancement of the computers came with the invention of the first four bit microprocessor in 1971. From 1971 till date, in the span of these 40+ years many operating systems came into existence (such as Windows 95, Windows 98, Windows 2000, Windows NT, Windows XP, Windows 7, Fedora, Mac, Redhat, Ubuntu, Kubuntu, Solaris etc.), many programming languages and web languages came into existence ( such as C, CPP, JAVA, .NET, HTML, XML, DHTML, SQL, PLSQL etc.), and many Multi-National Companies came into existence(such as Wipro, Genpact, Apple, Google, Tech Mahindra, Xerox, Oracle, SUN, Adobe, Microsoft and many more). But Internet is one of the key for the growth of each and every thing mentioned above. Cloud Computing is an emerging concept in which resources of computer infrastructure are provided over the Internet [1]. Cloud computing is a concept in which every device gets connected to the cloud which contains application, platform or Infrastructure or a mixture of them. People of 21st century are more familiar with smart phones rather than anything else. With the advent of phones such as IPhone and Android smartphones, the numbers of people using cloud are increasing substantially. Millions of people are using cloud in the present day scenario and it is equally important to provide the security to all the users who are using it. Cloud computing can be used as a utility to attract many people which can make software attractive as a service [2]. There are several security related issues with cloud which can be discussed in this paper.

Despite the numerous advantages offered by cloud computing, security is a big issue concerned with cloud computing. There are various security issues and concerns associated with cloud computing, among them being phishing, data loss and data privacy. There are different mitigation measures that cloud pioneers are currently using to ensure data stored in the cloud remain secure and confidential as intended. Encryption is one mitigation method used to ensure security in cloud computing. According to Krutz and Vines (2010), encryption involves coding of the data stored in the computing cloud such that hackers cannot gain access to the data. Data encryption seems to be the most effective method of ensuring security in computing (Krutz and Vines, 2010). However, it is of paramount importance to note that encrypted data is usually difficult to search or perform various calculations on it.
