What is cybersecurity?

The word cybersecurity refers to the process of protecting and securing data, networks, systems, and digital units such as computers and cellphones from exploitation by unauthorized personnel. Emphasizing the importance of cybersecurity is not a hard case.

Security breaches and exposure of, for example, financial data, personal information, and other company-sensitive data could cause significant adverse effects for your business.

Basic terms you need to know

Within cybersecurity, there are dozens of terms to know. Let us break down five of the most common ones.


A process is crucial to most companies. Authentication is all about verifying people and exclude those irrelevant to your company. For this purpose, there are different applications to use.


Today many companies and private persons operate in the cloud. The term covers a computer system resource that allows you to access files and services from anywhere in the world through the internet.


Encryption is simply a way to secure vital data and information, so it is inaccessible to third parties and other irrelevant sources. The data is encrypted using codes and ciphers. When this is done, the information becomes unintelligible and can only be decrypted with the correct key.


A Firewall is a network security system that monitors and controls incoming and outgoing traffic.

The system will automatically block traffic sources that do not fulfill a set of security rules.

There are three basic firewalls that companies use. These are called Packet Filters, Proxy Server Firewalls, and Stateful Inspection.


A system developed by Google in the middle of the 00’s that tests whether the user is a robot or an actual human being. Many websites use ReCAPTCHA to prevent spamming by bots.

Different types of cyberattacks you need to worry about as a business owner

When running a business, you should consider the likelihood of getting cyber attacked. Today there exist many types of cyberattacks, and criminals are getting more and more innovative. Below we bring four of the most common threats.


Phishing is one of the most frequent and common types of cyberattacks. Cybercriminals send treacherous emails that imitate real emails from valid and trustable sources. The primary purpose of phishing is to access sensitive data like credit card numbers and different logins.


Malware is a type of software designed to infiltrate computers to cause damage. Malware is an umbrella term that covers various kinds of cyberattacks like a virus, trojan horse, worm, and ransomware.


As mentioned above, ransomware is a type of malware. Ransomware prevents you from accessing files on your computer. As the name indicates, the intruder will often request a ransom to restore your access to the files.

DDoS Attack

Distributed Denial of Service (DDoS) attacks refers to the process of overflooding a system/software or a network with activity. This could be messages, traffic, or different kinds of requests. The goal is to paralyze the computer, system, or network.

SIEM got your back

Security Information and Event Management, or simply SIEM, is a cybersecurity software that delivers surveillance and tracking of every IT-related incident. SIEM collects and aggregates all generated data throughout the whole IT infrastructure of your company. The software gives real-time alarms, dashboards, and reports, making companies capable of reacting quickly and accurately to every security incident. Furthermore, SIEM makes it easier for you to monitor your company’s IT infrastructure and locate and troubleshoot potential breaches before they arise.
