Network Bandwidth And Data Upload Time

Cloud computing means Internet computing. So cloud data is accessible from anywhere on the internet, meaning that if a data breach occurs via hacking, a disgruntled employee, or careless username/password security, your business data can be compromised. Due to that, should be aware of using cloud computing applications that involve using or storing data that are not comfortable having on the Internet.

In today’s world of instant connectivity and information at users’ fingertips, it’s vital that sensitive information is safeguarded against those who seek to do personal harm and profit from gaining access to the data. The key behind keeping information safe is the method in which it’s protected and encrypted. In order to appreciate how information is secured, users must understand the encryption concepts behind it. To do this, one must comprehend the current encryption standards, the trends and developments in encryption technology, the importance of securing data, the government’s regulations pertaining to encryption, the companies involved in research and implementation, the implications of leaked or stolen data, and a brief look into

In this Paper we propose a model for provable data possession (PDP) that allows a client to store the data at an entrusted server to check that the server contains the original data without retrieving it. This model produces probabilistic proof of possession by sampling random block sets from the server, which significantly decreases I/O costs. To verify the proof the client maintains a steady amount of metadata. The challenge/response protocol sends a small, constant amount of data, which reduces communication of the network. However, the PDP model for remote data checking supports more data sets in extensively-spreaded storage systems. We propose two provably-secure PDP schemes that are more efficient than previous solution, when compared

Therefore the cloud server could not have any idea about the no of documents stored, length of the files . In addition ,when a data user request for any particular files, he receives the random number of blocks which contains the documents.

While there is an extensive amount of files on the Internet, not all are valuable enough to be saved. Companies have to choose what’s most important in order to save space in the cloud system they have (one of the many ways businesses and/or users have kept their documents safe and backed up just in case they were to ever lose the original location in which files were saved). Employees use mobile gadgets not only to be accessible to many things at once but to stay connected in the system that the workplace may have set in place for fluency during work hours. People have items such as phones and tablets that are also subject to hacking. Although these gadgets are very efficient, they place a huge threat to companies at

This report illustrates the Message Digest 6 (MD6) hashing algorithm, how it functions, and the essentialness of a hashing function. Besides, it depicts the qualities of this hashing capacity over its predecessor, and its present shortcomings.

It's physically out of your hands. You aren't sparing to a hard drive at your home. You are sending your information to another organization, which could spare your information a large number of miles away, so guarding that data is currently reliant on them. In the event that you have your PC set to naturally transfer duplicates to the cloud, at that point you can overwrite the cloud duplicates with your degenerate duplicates.

Cloud computing has become one of the most popular computing paradigms. Today, the number of cybercrimes against cloud computing is increased where attackers using new techniques and method that make the process of tracking them difficult. This makes digital investigators and practitioners to think about designing and developing new techniques and tools to cope with the cybercrimes investigation in the cloud environment. Digital forensics strategies, methodologies, and techniques have to evolve to become efficient and effective to investigate severe attacks and crimes in the cloud. Digital forensics is considered as the process of collecting, extracting and recovery of digital evidence as an admissible proof about a committed crime that will

One of the primary benefits of files as a data source is the ability to separate and analyze the types of files, which creates a specific signature based on the content and user (Marcella & Menendez, 2008). Data can be pulled from deleted files, slack space on a system’s hard drive, or free space, all of which provides information that can be useful to investigators. The directory location and allocation type for each file informs the data that has been collected, including a time stamp and whether tools have been used to hide the data. Each of these characteristics provides investigators easy-to-access information about a system. In addition, there are a variety of hardware tools that can be used to access data. This technology is fairly common, meaning that associated costs tend to be minimal when retrieving data from files (Purita, 2006).

Accessing private information using computer is not very difficult these days. Many ways have been discovered to gain access to the private information of individuals, without their knowledge. One of these ways includes accessing the transaction data of individuals.

Cloud computing is vast and so are the security threats. When a company opts for cloud computing, it will consider the advantages, but some of the companies fail to consider the vulnerabilities that might lead to data lost and misuse.

A cloud service account is very similar to most web-based account; access to the account requires a username and password for authentication. Threat such as phishing and person-in-the-middle attacks used to gain access to passwords can result in an attacker gaining access to a cloud service account. Once the attacker gains access to the account steal data, manipulate data, redirect traffic, or carry out attacks from your allocated resource which can devastate an organizations reputation (Cloud Security Alliance, 2011).

Dead files by dead accounts may not be removed without the cooperation of the corresponding users. In the paper “Steganographic Schemes for File System and B-Tree” [3], they have introduced StegFD, a practical scheme to implement a steganographic file system in which a plausible deniability to owners of protected files is offered. StegFD hides the selected files in a file system securely in such a way that, an attacker will not be able to trace their existence, even if the attacker has full knowledge of the hardware and software and data structures of the file system .They have also proposed two schemes for implementing Steganographic B-trees in a StegFD volume. In paper “A Multi-User Steganographic File System on Untrusted Shared Storage” [4] the threat to steganographic file systems (StegFS) is described which arises when the storage system is untrusted and is shared by multiple users. In such cases, the attacker could obtain multiple snapshots of the storage content and analyze them to deduce the existence of secret user data. To solve this problem, they have introduced a Dummy-Relocatable Steganographic (DRSteg) file system. It employs new techniques to share and relocate dummy data at

Cloud computing has become so famous; there is much widespread news about the cloud these days. This is mainly because of the exponential shift of the business applications from traditional models of software towards the Internet, and now through mobile devices. Cloud computing is a model that uses the network of remote servers that has been hosted on the internet rather than on a specific hardware. This would enable a better shared pool for storing, accessing and processing of data. With the huge information being available in the internet, the security for cloud computing has been challenging and this paper would elucidates the security threats of cloud computing also stating the possible countermeasures for them.
