What is cybersecurity?
Cybersecurity involves protecting systems, networks, and programs from digital attacks. These cyberattacks often aim to access sensitive information, modify or destroy it, extort money from users, or disrupt normal business operations.
Today, implementing effective cybersecurity measures is particularly complex. The number of connected devices exceeds the number of users, and cybercriminals are becoming increasingly ingenious.
To address these challenges, it is essential to implement a robust cybersecurity strategy, including advanced protection solutions, continuous monitoring, and regular employee training on security best practices.

What is cyber security?
IT cybersecurity involves protecting systems, networks and programs against cyberattacks. Technology plays a crucial role in providing companies and individuals with the tools they need to defend themselves against these threats. Three main entities need to be protected: endpoints (computers, smart devices, routers), networks and the cloud.
A solid cybersecurity strategy is based on multi-level protection, covering the computers, networks, applications and data you wish to protect. In an enterprise environment, it is essential that people, processes and technologies work in synergy to build a robust defense against cyber threats. A unified threat management system, such as that offered by Itnet Technologies, automates the integration of various security products, optimizing key security operations: incident detection, analysis and remediation.
Technologies commonly used to protect these entities include next-generation firewalls, DNS filtering, malware protection, antivirus software and email security solutions.
What is the role of cybersecurity?
Cybersecurity plays a vital role in protecting IT systems, networks and data from unauthorized access, attack and damage. In a world where digital transformation is taking center stage, businesses, governments and individuals are increasingly reliant on technology to store, process and exchange sensitive information. However, this increased reliance on technology also exposes users to growing cyberthreats such as viruses, malware, ransomware, phishing and many other forms of sophisticated attack. Cybersecurity intervenes to identify, prevent and respond to these threats, in order to guarantee the confidentiality, integrity and availability of information.
The role of cybersecurity is not limited to blocking external attacks; it also helps detect internal vulnerabilities and suspicious behavior that could harm the organization. Cybersecurity teams implement defensive measures such as firewalls, intrusion detection systems, data encryption and identity and access management tools to minimize risks. In addition, cybersecurity is crucial to regulatory compliance, as many laws require companies to protect their customers personal data and report security breaches.
Finally, cybersecurity plays a strategic role in an organization's resilience. By anticipating threats and planning appropriate responses, companies can better prepare for security incidents and reduce the financial, operational and reputational impact. Cybersecurity has thus become a pillar of business continuity, helping organizations to recover quickly from attacks and strengthen their defenses for the future.
Types of cyber threats
Phishing
Phishing is a method of cyberattack in which criminals send messages or e-mails that appear to come from legitimate sources, with the aim of deceiving users into revealing sensitive information, such as login credentials or banking details. Attackers often imitate financial institutions, e-commerce platforms or other trusted entities, to create a false sense of security for the victim. Phishing can also take the form of fake websites, designed to look like official sites, where victims are enticed to enter their confidential information.
Ransomware
Ransomware is a type of malware that encrypts a victim's files or systems, making data inaccessible until a ransom is paid. These attacks can be devastating for businesses, public institutions and private individuals, as they paralyze access to essential data, often with no guarantee of restoration even after payment. Ransomware is usually spread via malicious links, infected e-mail attachments, or exploited vulnerabilities in operating systems
The malware
The malware or malicious software, refers to any program or code designed to cause damage, steal information, or compromise computer systems. Malware includes various types of threats, such as viruses, which spread from one file to another, Trojans, which disguise themselves as harmless software to infiltrate systems, and spyware, which secretly collects information about the user without his or her consent. Malware is a pervasive and evolving threat, constantly used to compromise networks and devices.
Social engineering
Social engineering relies on the psychological manipulation of individuals to induce them to perform dangerous actions or reveal confidential information. Cybercriminals exploit trust, curiosity or urgency to gain access to systems or sensitive data. Social engineering techniques include fraudulent phone calls, fake emergency e-mails or even face-to-face interactions, in which attackers play on human emotions to deceive their victims.
Denial of service attacks (DDoS)
Denial of service attacks (DDoS) aim to make a website or online service unavailable by overloading it with useless requests. By generating massive traffic, attackers saturate the server's resources, preventing legitimate users from accessing it. These attacks, often orchestrated by botnets, can cause financial losses and tarnish the image of the targeted company. In some cases, these attacks are used to divert the attention of security teams while another attack is being carried out in parallel
Botnets
Botnets are networks of malware-infected computers controlled by cybercriminals. These zombie computers can be remotely activated to perform various malicious actions, such as launching denial-of-service attacks or sending mass spam, often without their owners' knowledge. Botnets represent a significant security threat, as they enable attackers to carry out large-scale attacks in a coordinated, untraceable fashion.
SQL injection attacks
SQL injection attacks target databases by exploiting loopholes in insecure SQL queries to access, modify or delete sensitive data. By manipulating SQL queries, attackers can obtain confidential information, such as login credentials or financial data. These attacks are particularly dangerous for companies storing sensitive information, as they can lead to costly data breaches and regulatory sanctions.
Session theft
Session theft (or session hijacking) involves hijacking a user session to access information or services to which that user has already been authenticated. This type of attack is often carried out on unsecured networks, such as public Wi-Fi networks, where attackers intercept session cookies to impersonate the victim. Session theft enables cybercriminals to access personal or business accounts and steal sensitive information without the user noticing immediately
