Computer security: a major issue for companies and individuals

In the digital age, cybersecurity has become a crucial concern for all spheres of our society. Cyber threats are omnipresent and can have devastating consequences for both businesses and individuals. This article explores the main challenges and issues of cybersecurity today.

Main Cyber Threats


Malware, or “malicious software”, includes a wide range of harmful programs such as viruses, worms, Trojans, and ransomware. They can damage systems, steal personal and professional data, or even hold entire networks hostage for ransom.


Phishing is a manipulation technique used to deceive users into disclosing sensitive information such as passwords or credit card numbers. These attacks often come in the form of fraudulent emails that appear to be from trusted sources.

Distributed Denial-of-Service (DDoS) Attacks

DDoS attacks involve overwhelming a server or network with requests, making it unavailable for legitimate users. These attacks can disrupt online services for hours or even days.

Essential Prevention Measures

Regular Updates

Keeping systems and software up to date is crucial to patch known security vulnerabilities. Businesses need to ensure they apply patches provided by vendors as soon as they are available.

Use of Strong Passwords

Using complex and unique passwords for each account is a simple yet effective measure to protect data. It is also recommended to use password managers to securely store this information.

User Training and Awareness

Training employees on good cybersecurity practices and raising awareness can significantly reduce human-related risks. These programs should include regular sessions to keep up with evolving threats and fraudulent techniques.

Security Regulations and Standards

NIS2 Directive

Starting October 2024, the NIS2 directive will become mandatory for over 160,000 companies in Europe. This regulation imposes strict measures to enhance cybersecurity and protect critical infrastructures against cyberattacks.

GDPR (General Data Protection Regulation)

The GDPR was implemented to protect the personal data of European citizens. By requiring the implementation of appropriate security measures, it aims to minimize risks related to unauthorized disclosure or data loss.

Emerging Technologies for Cybersecurity

Artificial Intelligence and Machine Learning

Artificial intelligence and machine learning are playing an increasing role in cybersecurity. These technologies can detect abnormal or suspicious behavior in real-time, even before an attack fully manifests. They are capable of analyzing massive amounts of data to identify patterns that may go unnoticed by human eyes.


Blockchain technology offers a high level of security due to its decentralized and immutable nature. It can be used to secure transactions and verify data integrity.

  • Advanced threat detection through artificial intelligence
  • Enhanced authentication through blockchain
  • Predictive analytics to anticipate attacks

Real-life Examples of Companies Strengthening their Security

Example of a SME in the Healthcare Sector

A SME specializing in medical devices recently invested in sophisticated cybersecurity solutions to protect their patients’ data. These investments include an advanced encryption system and next-generation firewalls.

Industrial Group and its Resilience Plan

A large industrial group has established a resilience plan to effectively deal with security incidents. This plan includes regular backups, attack simulations, and a dedicated team for a rapid response to any potential threat.

In conclusion, cybersecurity is essential today for preserving economic and personal interests. The risks associated with cyber threats require constant vigilance and continuous adaptation in the face of the ever-evolving techniques used by cybercriminals.
