Since both of them have the encryption key, they can write their plaintext and translate cipher text and whoever needs to read the cipher text can just use the encryption key to translate the cipher text to readable plaintext. Another type of encryption method is the public key or asymmetric algorithm requires two separate keys, one secret and the other public. Even though they are different, they have a common mathematical connection. In this method, the public key is used to encrypt the plaint text into cipher text and the private key is used to decrypt the cipher text to plain
CIA Model for Information Security This is one of the fundamental and integral concepts of Information Security and is widely used as a benchmark for evaluating and implementing information security in many organizations. The CIA Model covers 3 key areas of information, namely: Confidentiality – C, Integrity – I and Availability – A; commonly referred to as the CIA Triad and they form the core of information security measures in IT Infrastructure. Many information security standards are designed and implemented to protect one or more facets of the CIA Triad. (Whitman and Mattord, 2012) CIA Triad Figure 1: CIA Model for Information
Data integrity as a state defines a data set that is both accurate and valid. Furthermore, data integrity as a process, describes measures used to ensure validity and accuracy of a data set or all data contained in a database or other construct. For instance, error detection and data validation methods may be referred to as data integrity processes. Maintaining data integrity is important and key to the companies for several reasons as data integrity ensures the accuracy of the information recoverability, searching ability, traceability connectivity and analysis. Protecting the validity and accuracy of data also increases stability, performance and drive decision-making considering the data can be maintained and reused when needed.
1.1Identify legislation and codes of practice that relate to handling information in social care settings The Data Protection Act is a form of legislation, which is used to outline the legal obligations when handling an individual’s personal information. The legislation is used not only to protect the individual but to also protect those who are handling the information. 1.2Explain how legal requirements and codes of practice inform practice in handling information Under the Data Protection Act, there are particular requirements that have to be followed, in order for the information to be handle in the correct manner. These areas are listed as follows: You are only allowed to obtain information that is needed for a specific purpose. You
Hence, data security is critical for most businesses and even home computer users. Payment information, Bank account details, Client information, Research & Development files, Confidential files, Personal files can be hard to replace and potentially dangerous if it falls into the wrong hands. When the data is lost to hackers or a malware infection, it can have much greater consequences. Security in terms of confidentiality, integrity, authentication, non-repudiation, access control and availability is measured. Considering the above parameters, Cryptographic algorithms and protocol are very useful to keep a network system secure.
Today, encryption of personal and enterprise data is strongly recommended, and in some cases mandated by laws and regulations around the world. Cloud customers want their providers to encrypt their data to ensure that it is protected no matter where the data is physically located. Likewise, the cloud provider needs to protect its customers’ sensitive data. Strong encryption with key management is one of the core mechanisms that Cloud Computing systems should use to protect data. While encryption itself doesn’t necessarily prevent data loss, safe harbor provisions in laws and regulations treat lost encrypted on data as not lost at all.
Attack on data always happens without the person involve realize about it. This is why data encryption is important. Data encryption using asymmetric key is one of the most trustable data security algorithm. When the sender wants to send data or message, data encryption will change the data to an indecipherable state by using algorithms or theorems. Data encryptions are initially used by the authority military to communicate with each other during the old days.
Information security is an important aspect of any organization. Information security being a crucial aspect of any organization provides the following important benefits to an organization: It protects the ability of the organization to function, it enables the safe operation of applications and software that are implemented in the IT systems of the organization, it protects the data that the organization collects and uses, and it safeguards the technology assets that are used in the organization. Information security besides protecting the ability of an organization to function also ensures that the data that is collected by an organization is protected from malware infection and distortion. In addition to that, information security ensures that no unauthorized personnel gets an opportunity to intercept or decode the information during transmission, reception or
If information stored was not electronic data but stored on paper in a filing cabinet and the information wouldn’t be subjected too much security, with technology information can be protect by means of a variety of security measures to prevent unauthorised access or grant access to authorised users. There are many privacy areas impacted by of the use of technology. These areas include: •
