as someone with legitimate access to the network. Because information and data accessed by insiders can be easily copied, stolen, deleted, misfiled, or updated, insider threats can be some of the most damaging, harmful regardless of whether they occur due to user carelessness or do the malicious activity. • Physical Security- Physical Security is significant to preventing unauthorized access to sensitive data, information as well as protecting an organization’s personnel and their resources
Whenever an unauthorized individual or a party can view information, confidentiality is breached. Integrity: Integrity deals with maintaining the consistency, accuracy, and trustworthiness of data over its entire life cycle. Data must not be changed in the transition period, and steps must be taken to ensure that data is not altered by unauthorized people. Availability: Informational availability is that the information should be made available for the right people at the right time. If an attacker
efficiency advantages. Though a number of techniques, such as encryption and electronic signatures, are currently available to protect data when transmitted across sites, a truly comprehensive approach for data protection must also include mechanisms for enforcing access control policies based on data contents, subject qualifications and characteristics, and other relevant contextual information, such as time. It is well understood today that the semantics of data must be taken into account in order to
organization information security assets, non- technical managers should be exposed to the three main areas of accountability such as Confidentiality, Integrity, and Availability (CIA). By doing so, it helps to create a pro-active environment to preserve the confidentiality of the information, maintain its integrity, and also ensure its availability. Since the value of information is so high, companies are thriving all the time to develop
aim of the paper “Addressing cloud computing security issues” is to both evaluate current cloud computing security based on observing and identifying security requirements of these systems, and to introduce a novel technique to provide confidentiality, availability, and integrity in cloud computing systems. The authors of this paper believe that this may be accomplished by using a Trusted Third Party (TTP) for authentication and authorization. At the beginning of this paper the authors describe
password for only the students who are registered into the subject to check the lecture material and updates. 4) Confidentiality - Education& Training-Storage: The university should educate the students and faculty to access authorized data without exposing the data to outsiders. 5) Confidentiality- Policy& Practice- Storage: The university should have a policy, such as the access to lecture notes posted or info of the subject can be accessed by registered students only 6) Confidentiality-Technology-
When designing a new model to secure big data implementation in cloud computing, three requirements were under close examination: Confidentiality, integrity, and availability. Confidentiality opt to keep big data secret in cloud computing for unauthorized access, in our model we are willing to keep data secret even from the cloud service provider, therefore we propose to encrypt data before send it to the cloud, the encryption method is discussed below. Integrity prevents any kind of alter (modify or
services. The acceptance of cloud computing model among the consumers is based on its cost-effectiveness in terms of maintenance of the resources along with the flexibility and efficient performance. Nonetheless, certain concerns associated with the data security and credibility of the services are still there that are required to be eradicated for its sustained acceptance within the ICT industry.
It protects user’s privacy and ensures data integrity and secrecy by applying an anthology of rules and policies. Cloud users are granted different levels of access permissions and resource ownerships based on their account type. Only authorized users can access the authorized parts of the encrypted data through identity-based decryption algorithm. For example, in a healthcare cloud, not all practitioners have the same privileges to access patient’s data, this may depend on the degree to which a
leads to the security challenges faced by it at every step of its growth. Three main threats facing computer network security include: hackers, computer virus and denial of service attack. Safety factors of the network are mainly: resources sharing, data communication, computer virus and TCP/IP protocol security flaws. A safety network system should include at least three kinds of measures: legal measures, technical measures and review and management measures. The paper analyzes the main threat facing
