What is Cybersecurity? – Types, and Importance


Nowadays, it is impossible not to hear about cybersecurity on the Internet and how our bank details, personal files, or computers can be hacked. So protecting our digital space is crucial. Cybersecurity in companies is just as critical or even more so than in the private sphere. Therefore, your company’s digital assets must be protected against external threats.

What is Cybersecurity?

By cybersecurity, we understand those strategies and actions a company or individual carries out to protect and defend their digital assets from possible cyber attacks, such as information theft and device control.

It is a branch of computing that is increasingly necessary since our level of online connection is increasingly higher and more frequent. Specifically, cyber attacks are a constant threat to companies of all sizes.

It is not only necessary to protect the computer equipment but also the network connections. Any technological device can and should be protected against these possible threats, especially if they have access to personal, banking, or company data.

What is Cybersecurity About?

A successful cybersecurity approach has multiple sheets of protection spread across the computers, networks, programs, or data one intends to keep safe. In an organization, people, processes, and technology must complement each other to create an effective defense against cyberattacks. A unified threat management structure can automate integrations between select Cisco security products and accelerate essential security operations functions: detection, investigation, and remediation.


Users should understand and follow basic data security principles, such as choosing strong passwords, being cautious with email attachments, and backing up data. Learn more about basic cybersecurity principles.


Organizations must have a structure in place to handle suspected and attempted cyberattacks. A reputable facility can guide you and explain how you can identify attacks. Protect systems, detect and respond to threats, and recover from successful attacks. See the video explanation of the NIST Cybersecurity Framework.

Technology is necessary to provide organizations and individuals with the information security tools to protect themselves from cyber attacks. Three important entities must be protected: endpoint devices (such as computers, smart devices, and routers), networks, and the cloud. Standard technologies that protect these entities include next-generation firewalls, DNS filtering, malware protection, antivirus software, and email security solutions.

Types of Cybersecurity

A good cybersecurity strategy for companies or individuals should focus on three main objectives: Attack prevention, threat detection, and recovery.

Preventive Cybersecurity

The preventive cybersecurity strategy is responsible for preventing attacks. In this case, the objective is to avoid threats from touching our devices. In other words, it is about shielding devices, networks, and software against attacks and preventing them from entering.

It is the most common type of cybersecurity. At its most basic level, we find applications for firewalls, antivirus, etc. The new Next Generation Firewalls are more advanced and monitor Internet connections. These applications are necessary, but other customized solutions can also be applied to large companies.

A standard preventive cybersecurity technique is ” pentesting,” which consists of controlled attacks on the company’s computer system to identify weak points and flaws in the cybersecurity system.

Detection Cybersecurity

Detection cybersecurity would be the next level. If there is a threat trying to access our device or that has somehow already managed to enter, the cybersecurity system should detect it and block it (in the case of detection before entry) or react to the threat (if it has already entered on the device).

Recovery Cybersecurity

It would be the ultimate level of cybersecurity. If the threat manages to overcome the previous barriers, the device recovery strategies will come into play, isolating and expelling the danger.

In this case, initiating actions to recover and restore any file that may have been damage or compromised during the attack would also be necessary.

Why is Cybersecurity Important?

In today’s joined world, everyone benefits from advanced cyber defense programs. At the individual stage, a cybersecurity attack can result in everything from identity theft to extortion attempts and the loss of essential data, such as family photos. In addition, everyone relies on critical infrastructures such as power plants, hospitals, and financial services companies. Protecting these and other organizations is essential to the functioning of society.

Everyone profits from the work of cyber threat researchers. Like Talos’ team of 250 threat researchers, who investigate new and emerging threats and cyberattack strategies. They reveal new resistances, educate the public on the importance of security, and strengthen open source tools. His work makes the Internet safer for everyone.


Computer security, cybersecurity, or info technology security is the safeguard of computer systems and networks from information disclosure, theft of, or damage to their hardware, software, or electronic data, as well as from the disruption or misdirection of the services they provide.
