What is Cybersecurity? Cybersecurity Threats, Methods and Technology

What Is Cybersecurity? The Internet was not designed to be as big as it is today, so that means it’s fundamentally insecure. Cybersecurity developed as a defensive solution to protect any interconnected systems from cyber threats and attacks. 

What is Cyber Security
Implementing effective Cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative
The Internet was not designed to be as big as it is today, so that means it’s fundamentally insecure. Cybersecurity developed as a defensive solution to protect any interconnected systems from cyber threats and attacks.  
Systems Vulnerable to Threats
Networks, devices, applications, and data centers are examples of systems vulnerable to threats. 

Types of Cybersecurity Threats

Common types of cyber threats include data breaches, identity theft, malware, ransomware, phishing attacks, and social engineering. Cybersecurity is used as a general umbrella term. 
Type of Cybersecurity Threats


Phishing is the practice of sending fraudulent emails that resemble emails from reputable sources. The aim is to steal sensitive data like credit card numbers and login information. It’s the most common type of cyber attack. You can help protect yourself through education or a technology solution that filters malicious emails.


Ransomware is a type of malicious software. It is designed to extort money by blocking access to files or the computer system until the ransom is paid. Paying the ransom does not guarantee that the files will be recovered or the system restored.


Malware is a type of software designed to gain unauthorized access or to cause damage to a computer. 

Social Engineering

Social engineering is a tactic that adversaries use to trick you into revealing sensitive information. They can solicit a monetary payment or gain access to your confidential data. Social engineering can be combined with any of the threats listed above to make you more likely to click on links, download malware, or trust a malicious source.


As the internet grows, Cybersecurity has become more specialized to include application security, network security, cloud security, data loss prevention, identity, and access management, mobile security and endpoint security. An effective cybersecurity approach should be dynamic and adaptive, and the approach should include people, processes, and technology that complement each other. Let’s look more closely at the three fundamental parts. 

People are end-users and cybersecurity professionals 

End users are those people who regularly use systems or devices. They need to understand security best practices, learn how to backup data, and undergo routine training one merging cybersecurity threats. Cybersecurity professionals can include a chief information security officer, security engineers, security architects and security analysts. 

Processes help people know how to respond to or prevent a threat 

Typically, a process is outlined in business continuity or disaster recovery framework. The framework should explain how threats are detected, removed and prevented. The process also helps protect the system by detailing how to strengthen a system with policies all end-users should follow, like password strength rules and mandatory system updates. 

Technology helps processes work together 

Security tools are used to carry out cybersecurity defenses, professionals employ cybersecurity technology like firewalls, anti-malware and antivirus software, DNS filters, and intrusion detection systems so that people can be the most productive and safe on the internet. 

Security Tools for Cybersecurity Defenses

With the growth of the Internet of Things and the idea of a connected world, organizations need to take precautions with safeguarding personal intellectual and sensitive information. Staying informed about threat intelligence, and being cautious about internet activity, is a good way to start building a cyber defense strategy.


Why is cybersecurity important?

In today’s connected world, everyone benefits from advanced cyber defense programs. At an individual level, a cybersecurity attack can result in everything from identity theft, to extortion attempts, to the loss of important data like family photos. Everyone relies on critical infrastructures like power plants, hospitals, and financial service companies. Securing these and other organizations is essential to keeping our society functioning.
Everyone also benefits from the work of cyber threat researchers, like the team of 250 threat researchers at Talos, who investigate new and emerging threats and cyber attack strategies. They reveal new vulnerabilities, educate the public on the importance of cybersecurity, and strengthen open source tools. Their work makes the Internet safer for everyone.
