Cyber security is the use of systems and tools to protect computers, software, data and information systems from threats like viruses, worms, Trojan horses, spyware, malware, hacking attempts (denial of service attacks, phishing, spoofing and so forth) and unauthorized access. The term is also used to describe a range of other related activities, including risk assessment, the creation of secure configurations and education and awareness.
The field has become increasingly important as it deals with a wide array of threats that affect the daily functioning of businesses and organizations in all sectors of the economy. These include extortion, the theft of intellectual property such as design plans or databases and even the disruption of business activity.
Many of these threats come in the form of malware, a virus that infects computers and slows them down to the point of being unusable, or ransomware that demands money for releasing the files. Another common danger is the theft of customer lists and passwords sent through unencrypted email or written on a sticky note in an employee’s cubicle, or the loss of company laptops that contain valuable business data.
Companies must have in place a dense mechanism to prevent these threats, or face the risk of losing valuable data and a great deal of time and money that would take a long time to get back on track. This is especially important for those with remote work policies that allow employees to work from home or other locations outside the office, requiring a higher level of cyber protection. MDR
