What does cyber security mean? And what are its types?

Cybersecurity is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks. Also known as IT security or electronic information security, the term applies in a variety of contexts, from business to mobile computing, and can be divided into several common categories. .

Network security is the practice of securing a computer network from intruders, whether targeted attackers or opportunistic malware. Application security focuses on keeping programs and devices free from threats. A hacked application can provide access to data designed to protect it. Successful security begins at the design stage. Long before the software or hardware is deployed.

Information security protects the integrity and privacy of data, both in storage and in transit. Operational security includes the processes and decisions about handling and protecting data assets, the permissions users have when accessing a network, and the procedures that determine how and where data can be stored or shared all fall under this umbrella.

Disaster recovery and business continuity define how an organization responds to a cybersecurity incident or other event that causes loss of operations or data. Disaster recovery policies dictate how an organization restores its operations and information to return to the same operating capability as before the event. Business continuity is the plan that The organization gets used to it as it tries to operate without certain resources.

The scale of the global cyber threat continues to evolve at a rapid pace, with the number of data breaches increasing every year Risk Based Security About 7.9 billion records were exposed to data breaches in the first nine months of 2019 alone, which is more than double the 112% number of records disclosed in the same period in 2018.

Medical services, retailers and public agencies saw the largest number of violations, and criminals were responsible for the most incidents. Some of these sectors are more attractive to cybercriminals because they collect financial and medical data, but all companies that use networks for customer data, corporate espionage or customer attacks can be targeted.

As the scale of the cyber threat continues to grow, the International Data Corporation expects global spending on cybersecurity solutions to reach $133.7 billion by the end of 2022, and governments around the world have responded to the growing cyber threat by providing guidance to help organizations implement effective cybersecurity practices.

In the United States, the National Institute of Standards and Technology (NIST) establishedNest) A cybersecurity framework, to combat the spread of malicious code and help early detection of it. The framework recommends continuous, real-time monitoring of all electronic resources.

There are three types of cyber threats that cybersecurity addresses:

1. Cybercrime involves individual actors or groups targeting systems for financial gain or disruption.

2. Cyber ​​attacks often involve the collection of politically motivated information.

3. Cyber ​​terrorism aims to undermine electronic systems to create a state of panic or fear.
