Kerberos provides a secure authentication scheme. Authentication is needed to restrict the intruders and malicious users. The major security issues discussed are privacy of the data, integrity of data and authentication mechanism which is not there in Hadoop. Hadoop supports Kerberos for authentication and many security features can be configured with the Hadoop to restrict the accessibility of the data. The data can be associated with the user names or group names in which data can be accessed. Kerberos is a conventional authentication system, improved authentication systems can be used which are more secure and efficient than
Cloud is the result of a decade research in the field of distributing computing , utility computing, virtualization , grid computing and more recently software, network services and web technology which is changeable evolution on demanding technology and services also as looking to the rapid growth of cloud computing which have changed the global computing infrastructure as well as the concept of computing resources toward cloud infrastructure. The important and interest of cloud computing increasing day by day and this technology receives more and more attention in the world (Jain, 2014) the mostly widely used definition of cloud computing is introduced by NIST “as a model for enabling a convenient on demand network access
Pretty Good Privacy, known as the PGP, is a popular program for encryption and decryption of data, providing security services for electronic mail messages and data files.
Security versus privacy is becoming a major issue in today’s society. Recently, the National Security Agency has been the victim of scrutiny due to allegations of espionage. Similar claims not only stem from the authority, but also come from the public as well. For example, one is enjoying a night out in a restaurant when a group of teenagers arrives. Before it is noticed, some of the teenagers take photos with a cell phone. The picture encompasses most of the area occupied; therefore, every person in that general area is included in it. A few moments later, one teen uploads that picture to various social media websites to share along with captions stating the current location. Although not a single person gave consent, pictures are being circulated with thousands of strangers in the innumerable realms of the internet. Not only are these pictures all over the web and an invasion of privacy, but people viewing those pictures are able to discover recent whereabouts with the simple click of a button. Due to technology’s rapid advancements, similar acts such as these are becoming nearly inevitable. But, these are the very same advancements that help us live in a free and open society. In order to avoid intrusions yet maintain safety, restrictions should be put upon consumer devices, capabilities of security devices, and government abilities.
Securing Personally Identifiable Information is critical and important because of the fact that PII is used to distinguish one person from another. Each piece of information is uniquely given to a specific individual. Having one thing unsecured, could give someone access to that unsecured item and so much more. If I had my social security card out in the open and someone was able to somehow get ahold of my SSN, it would give them unlimited access to pretty much everything else about me. They would be able to figure out my full name, birthday, address, etc. Having this information available could lead to the person getting credit cards in my name, getting access to my already opened credit cards, and even worse, stealing my identity. To prevent Identity theft, I will make sure my PII is secured and locked away. I will use the
The healthcare industry has access to a patient’s personal health information, in electronic and paper form, and is responsible for protecting this information. The Health Insurance Portability and Accountability Act (HIPAA) establish requirements for the healthcare industry. The establishment and implementation of an effective information security plan is critical to meet these requirements and ensure this protection. There are however challenges and risks that must be addressed. Cloud computing can be defined as the use of computer resources without the expense of owing the hardware and software. Cloud computing is becoming more and more popular in major corporations as a way to gain use of specific programs, applications and even hardware by way of the Internet.
The cloud computing is the practice that enables access to the shared pool of configurable computing resources which can be dynamically provisioned. It refers to both the applications delivered as service as well as hardware and system software in the data centres that provide those services. The attractive features of cloud computing such as on-demand access, high scalability, reliability, cost savings, low maintenance and energy efficiency bring benefits to both cloud service consumers and providers.
Data encryption refers to the process of transforming electronic information into a scrambled form that can only be read by someone who knows how to translate the code. In nowadays business world, it’s the easiest and most practical way to secure the information that we stored and processed, and it’s significant for our sensitive information. For example, as electronic commerce is popular now, the vendors and retailers must protect the customers’ personal information from hackers or competitors. They also have many business files or contracts that need to be strictly protected. Without data encryption, these important information may fall into wrong hands and be misused by others. Besides, data encryption may be used to secure sensitive information that exists on company networks, or create digital signatures, and help to authorize in business. No one should underestimate the importance of encryption. A little mistake in encryption may make sensitive information revealing, or even result in illegal and criminal accuse.
BitLocker™ Drive Encryption is a proprietary cryptography tool designed by Microsoft to provide enhanced data protection through
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.
Data encryption refers to the transformation of data into a structure that makes it unreadable by anyone without a secret decryption key. It ensures that messages can be read only by the planned recipient. Encryption is the procedure of obscuring information to create it unreadable without special information. Only organizations and individuals with an abnormal need for secrecy have actually made good use of it. Nowadays, encryption is one of the most important technologies for maintaining your privacy and the security of important information. This helps out greatly especially when E-Commerce is being used.

In the world, where security breaches and information stealing occurs more frequently, a service offering a secure data storage is a significant factor of a security arrangement. Encryption is simply stated as the practice of systematic information scrambling, so that it can be unscrambled later [10]. Data encryption interprets data into a different form, or cryptograph, so that a person holding a secret key (i.e. a decryption key) or password can access that data. The encrypted data is known as cipher text, whereas the unencrypted data is termed as plaintext. Presently, encryption is considered as one of the most effective data security technique and is widely used by a number of organizations for the purpose of secure and reliable transmission of data containing secret information. Asymmetric encryption and Symmetric encryption are two main types of encryption techniques.
There must be some solid personal recognition schemes for a wide variety of system either to determine or conform the identity of the people who do services. The purpose is that to ensure the provided services are accessed only by the user and no other people can do so. Some of the examples of such process includes secure access to computers, laptops, buildings, security places etc. In absence of these schemes these systems are vulnerable to misuse. Therefore biometrics is introduced which refers to a secured access of an individual by automatic recognition based upon their behavioral and physiological characteristics. Using Biometrics we can conform an individual’s identity based on “who he is” rather than “what he has”. This paper gives a brief view of Biometrics, its advantages and disadvantages, the advancement of biometrics in now a days security management.
