Cybersecurity refers to the protection practice for the hardware, software, and data from being destroyed, altered or leaked by accidental or malicious reasons to ensure the system runs continuously and the network service is not interrupted. An effective cybersecurity methodology has multiple levels of protection spread across the computers, networks, programs, and data that one intends to remain secure. For an effective defense from cyber-attacks, the people, processes, and technology in any organization should complement one another.
The cybersecurity can be divided into physical security and logical security. Physical safety refers to the physical protection of system equipment and related facilities from damage and loss. Logical security includes integrity, confidentiality, and availability of information.
