The Cyber Security on a whole is a very broad term but is based on three fundamental concepts known as “The CIA Triad“.
It consists of Confidentiality, Integrity and Availability. This model is designed to guide the organization with the policies of Cyber Security in the realm of Information security.
It defines the rules that limits the access of information. Confidentiality takes on the measures to restrict the sensitive information from being accessed by cyber attackers and hackers.
In an organization, peoples are allowed or denied the access of information according to its category by authorizing the right persons in a department. They are also given proper training about the sharing of information and securing their accounts with strong passwords.
This assures that the data is consistent, accurate and trustworthy over its time period. It means that the data within the transit should not be changed, altered, deleted or illegally being accessed.
Proper measures should be taken in an organization to ensure its safety. File permissions and user access control are the measures controlling the data breach. Also, there should be tools and technologies implemented to detect any change or breach in the data. Various Organizations uses a checksum, and even cryptographic checksum to verify the integrity of data.
To cope with data loss or accidental deletion or even cyber attacks, regular backups should be there. Cloud backups are now the most trusted solution for this.
Availability in terms of all necessary components like hardware, software, networks, devices and security equipment should all be maintained and upgraded. This will ensure the smooth functioning and access of Data without any disruption. Also providing constant communication between the components through providing enough bandwidth.
it also involves opting for extra security equipment in case of any disaster or bottlenecks. Utilities like firewalls, disaster recovery plans, proxy servers and a proper backup solution should ensure to cope with DoS attacks.
For a successful approach, it should go through multiple layers of security to ensure protection to every constituent of CyberSecurity. Particularly involving computers, hardware systems, networks, software programs and the data which are shared among them.
