What It Is
Unlike physical threats that prompt immediate action, cyber threats and attacks are often difficult to identify or comprehend. Cybersecurity involves preventing, detecting, and responding to cyber incidents. Virtually all modern organizations – including governments, hospitals, corporations, banks, and utilities – rely on computer systems for their operations and data management, and are therefore vulnerable to cyber attacks.
The so-called “attack surface” that may be vulnerable to bad actors can include computer hardware, tablets, phones, and many other web-enabled devices and appliances in the so-called “internet of things.” Among the dangers of cyber attacks are intruders erasing entire systems, holding data or operating systems for ransom, stealing confidential or personal information, breaking into systems and altering files, or using a computer or device to access contact lists and attack or infect others.
