Computer security is one of the most important issues in organizations which cannot afford any kind of data loss. Confidentiality can be ensured by using role-based security methods to ensure user or viewer authorization (data access levels may be assigned to a specific department) or access controls that ensure user actions remain within their roles (for example, define a user to read but not write data).” Because of this, many information security specialists and help desk technicians spend a good number of their work hours granting administrative access and monitoring data access. Formal sciences: the study of formal systems, such as those under the branches of logic and mathematics, which use an a priori, as opposed to empirical, methodology. These issues are not limited to natural disasters, computer/server malfunctions etc. Understanding the major security concerns, and how current trends, software, and other measures can help address them, are key components in creating a solid security strategy. It’s important for business leaders to ensure that their computer security elements focus on a systems’ ability to function well enough and consistently enough to ensure that information and data are available and don’t affect user experience. It refers to having access to the information when needed. It means that the information is visible to the authorized eyes only. Computer Security is important for protecting the confidentiality, integrity, and availability of computer systems and their resources. The range of means by which the security and integrity of computing resources can be threatened is very broad, and encompasses: 1. protected for three reasons: • To prevent theft of or damage to the hardware • To prevent theft of or damage to the information • To prevent disruption of service Strict procedures for access to the machine room are used by most organizations, and these procedures are often an organization’s only obvious computer security measures. Hence, keeping your data safe is keeping your company safe and information security procedures are essential to any business. Computer security tactics aren't often thought about until a problem arises — and at that point, a break in security can cause harmful and potentially major issues. Computers have helped fuel the cashless economy, enabling the widespread use of credit cards, debit cards and instantaneous credit checks by banks and retailers. Data integrity is a major information security component because users must be able to trust information.” One way to increase the reliability and integrity of data is through validation methods like blockchain and other software solutions. Information security covers a wide area of various practices and techniques.

It’s important for business leaders to ensure that their computer security elements focus on a systems’ ability to function well enough and consistently enough to ensure that information and data are available and don’t affect user experience. Availability of the information is a pretty straightforward concept. In order to fulfil these requirements, we come to the three main elements which are confidentiality, integrity, and availability and the recently added authenticity and utility. As a term laden with associations, information security covers a wide area of practices and techniques but simply put, it is protecting information and information systems from various undesired and or dangerous situations such as disruption, destruction, or unauthorized access and use.
