Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. Data security refers to protective digital privacy measures that are applied to prevent unauthorized access to computers, databases and websites. Data security is critical for most businesses and even home computer users. Encrypted data is commonly referred to as ciphertext, while unencrypted data is called plaintext. While IT security protects both physical and digital data, cyber security protects the digital data on your networks, computers and devices from unauthorized access, attack and destruction. Security, on the other hand, refers to how your personal information is protected. Data security refers to the protection of data, while data integrity refers to the trustworthiness of data. Data privacy, digital trade, and national security are intertwined. It is a broad term that includes a multitude of processes, tools and methodologies that ensure security within a database environment. Technical security controls protect data that is stored on the network or which is in transit across, into or out of the network. Data security focuses on how to minimize the risk of leaking intellectual property, business documents, healthcare data, emails, trade secrets, and more. It’s also known as information security, IT Security, or electronic information security. The PCI DSS was created jointly in 2004 by four major credit-card companies: Visa, MasterCard, Discover and American Express. The Payment Card Industry Data Security Standard (PCI DSS) is a widely accepted set of policies and procedures intended to optimize the security of credit, debit and cash card transactions and protect cardholders against misuse of their personal information. Here's a broad look at the policies, principles, and people used to protect data. Data security is the process of maintaining the confidentiality, integrity, and availability of an organization’s data in a manner consistent with the organization’s risk strategy. The term applies in a variety of contexts, from business to mobile computing, and can be divided into a few common categories. They allow administrators and management to create access control and perform security tests to audit existing security. Your data — different details about you — may live in a lot of places. So as a company, you don’t want to lose your data or access to it. Data encryption translates data into another form, or code, so that only people with access to a secret key (formally called a decryption key) or password can read it. The ideal endpoint protection must focus on safeguarding data. Access to sensitive data should be limited through sufficient data security and information security practices designed to prevent unauthorized disclosure and data breaches.. Data that contain personal information should be treated with higher levels of security than data which do not, as the safeguarding of personal data is dictated by national legislation, the Data Protection Act 2018, which states that personal data should only be accessible to authorised persons.
