Why is cybersecurity important?
Cybersecurity is important because it keeps the services that the modern world is built upon functioning as they should. Most systems that manage services we take for granted have moved online, from financial organizations and medical care to electrical grids that power whole cities. Cybersecurity is the defensive wall that keeps these systems safe from cyberattacks.
Without adequate IT security, your banking information, private messages, or online activities would be out in the open for anyone to see (this is where cybersecurity tools like a VPN can help). These aren’t hypothetical situations, either — the brief history of cybersecurity shows that hackers have infiltrated United States government systems, disrupted national power grids, and blackmailed billions of dollars out of people and companies through ransomware attacks.
Types of cybersecurity
Cybersecurity can be broadly divided into five types, although they aren’t set in stone — cybersecurity tools can easily belong to more than one category.
Types of cybersecurity threats
A cyberattack or cyber threat is any malicious act seeking to damage, steal, or secretly alter data. Here are the most common cyber threats.
Social engineering is a set of techniques that manipulate the victim into doing something that the hacker wants. It’s an umbrella term that includes phishing, vishing, catfishing, pretexting, and more.
Distributed denial of service
In DDoS attacks, a network of infected computers overwhelms their target with enormous amounts of traffic. It can slow websites to the point where it’s impossible to use or take them down for some time.
Criminals insert a malicious script into a regular website. The software can then record your sensitive information like what you type into login fields when accessing your online bank account.
In a dictionary attack, a hacker uses a predefined list of words and phrases to guess your password. Most attacks utilize password-cracking software that can take millions of guesses from a list of most common passwords.
Hackers use login information obtained through social engineering or from leaked databases to crack every account you have. For example, if a criminal gets their hands on your email password, they’ll try to access your other accounts using the same credentials.
Cyber threat actors
A cyber threat actor (also known simply as a “threat actor”) is a person or group that carries out or aids cyberattacks on devices, systems, and networks. Here are the five most common cyber threat actors today.
