IT security, a survival issue for companies

IT security, a survival issue for companies


Cyberattacks have become a daily concern for companies. With threats such as ransomware, phishing and other malware on the rise. How can we shield ourselves against these digital threats ?

Numerous factors emphasize the strategic importance of cybersecurity for companies :

First of all, cyberattacks, which fall into the categories of cybercrime, image damage, espionage and sabotage (ISO 27000) can lead to considerable financial losses. For instance, the theft of confidential data may lead to a loss of competitiveness and even an interruption of activity.

Regulatory compliance is another issue. The GDPR or the NIS Directive now imposing obligations on IT security and the management of personal data. Failure to comply with these regulations exposes you to significant financial penalties.

In addition, cybersecurity enhances a company's resilience, ensuring business continuity during major incidents.

Finally, strengthening your digital defenses reassures your partners. This demonstrates that the company controls the risks and secures the data entrusted to it.


What tools are used in cybersecurity ?

  • Firewalls filter incoming and outgoing flows. They stop intrusions and isolate the internal network. It should be noted that next-generation firewalls integrate artificial intelligence and global knowledge bases for optimized protection
  • Infrastructure monitoring provides real-time visibility into threats. Thanks to dashboards and customized alerts, anomalies are detected quickly. This speeds up the response in the event of an incident
  • Antiviruses detect and neutralize malware. They are based on databases of known threats. Publishers are constantly updating these databases
  • Securing websites is essential to protect against SQL injections, cross-site scripting and other web vulnerabilities. We use, among other things, WAFs (web application firewalls) and security scans
  • VPNs (virtual private networks) encrypt data to ensure the privacy of exchanges. At a time when remote work is becoming more widespread, this solution allows companies to offer flexibility to their employees while respecting high IT security standards
  • Data leak protection solutions prevent sensitive information theft through data encryption, access traceability, and outbound filtering
  • Network segmentation and partitioning solutions help reduce impacts in the event of an attack or a compromise
  • Intrusion probes monitor traffic and can identify anomalous activity symptomatic of cyberattacks
  • Automated backup management guarantees data availability in the event of a disaster. Regular backups to dedicated, secure spaces allow critical information to be restored quickly
  • Data encryption and multi-factor authentication are two additional essential tools to secure your information systems

These tools are complementary and should be combined for overall protection. Their meticulous configuration is the cornerstone of successful cybersecurity.


What are the approaches and best practices in cybersecurity ?

  • Access and authentication management are paramount in cybersecurity. It is essential to implement a strong, multi-factor password policy and restricted privilege entitlements
  • Incident response and remediation require dedicated procedures (BCP/DRP). They define the actions to be taken in the event of an attack to limit the impact and restore normal operation
  • The management of critical assets involves identifying and then strengthening their security. Mission-critical servers, storage arrays and network equipment are subject to specific measures (frequent backups, increased monitoring, etc.)

Beyond technical solutions, humans are the weakest link in the cyber protection chain. Thus, raising awareness and training employees are crucial, especially against phishing attempts.

In line with these cybersecurity / digital security requirements, new organizational approaches such as Zero Trust are now strengthening companies' security arsenals.


How do you set up an effective cybersecurity ?

There are several key steps involved in implementing effective cybersecurity.

First of all, it is essential to carry out a thorough security audit. This helps identify vulnerabilities and accurately map risks. On this basis, we define a security policy adapted to the business challenges.

The next step is to choose the most suitable technical solutions for the existing infrastructure. The integration and configuration of cybersecurity solutions requires rigor and expertise for the best possible protection.

As mentioned above, raising awareness among employees is also essential, and includes regular training on good digital practices.

Finally, pentests and simulations of cyberattacks make it possible to validate the robustness of the system.

Cybersecurity needs to be continuously monitored to respond to the ever-changing threat landscape.
