Cybersecurity: understanding everything about this exploding phenomenon

According to INSEE, already in 2019, 68% of attacks suffered by French companies concerned illegal access to a computer system.

‍

Cybersecurity is therefore becoming a key issue for the health of our businesses. _rzilient is very active on this subject, and makes every effort to ensure that our solutions guarantee your safety.

‍

Let's go and discover the cybersecurity !

Overview of cybersecurity

Definition of cybersecurity

So what is cybersecurity?

Its formal definition is as follows. It is all of:

• practices,
• technologies and software,
• and processes,

designed to protect computer systems, networks, data, and users from threats related to the use of the Internet and information technology.

‍

As you can see, the subject is vast!

Cybersecurity involves, first of all, protect your sensitive data and to prevent cyberattacks and intrusions against your business.

‍

For this, it is important to:

• detect incidents of safety,
• Respond to it effectively,
• and be able to rehabilitate your computer systems, in case of attack or disturbance.

‍

The importance of cybersecurity in your business

Cybersecurity has become an increasingly important issue in an increasingly connected world.

‍

‍

Moreover, do you still have a computer or smartphone in your company that is not connected to the Internet?

‍

For their part, cybercriminals are using ever more sophisticated techniques in order to access data illegally and to online resources.

‍

And their playground is global! Indeed, it is possible to suffer an attack from an attacker on the other side of the world.

‍

The main challenges of cybersecurity

Many types of attacks and threats exist today, including viruses, malware, phishing attempts, etc.

‍

The concrete consequences of these computer attacks are as follows:

• theft of your sensitive data,
• Account hacking,
• sabotaging your computer system.

‍

According to a study carried out by the insurance company Hiscox in 2021, the average total cost of a cyberattack is... 4 million euros! This figure concerns mainly ETI and large companies. However, in VSEs and SMEs as well, the cost of an attack can be relatively significant: up to 50,000 euros.

‍

And as far as the sectors concerned are concerned, no one is safe anymore! All types of organizations are the target of cybercriminals: businesses, local authorities, individuals, etc.

‍

In short, it is high time to put in place protective measures!

‍

Cybersecurity methods

Let's now focus on the main tools to fight cyberattackers.

‍

Among these, there are several key tools:

• The firewalls,
• antiviruses,
• cryptography,
• identity and access management,
• securing workstations.

‍

These tools are brought to you by _rzilient as part of our all-in-one outsourcing platform, so that you can work with peace of mind.

‍

Cybersecurity risks

Now, here are the three most frequently encountered computer security breaches in businesses.

Human “weaknesses”

The first of the faults observed in most companies is constituted by purely human errors.

‍

These include, for example:

• passwords that are too simple and therefore easy to guess,
• a lack of vigilance on the part of users,
• the absence of a process concerning software installations,
• dangerous behaviors using the Internet,
• too much trust when opening emails from unknown recipients, etc.

‍

All these small daily actions, which seem trivial, can be access points for cyberattackers.

‍

The solution? Regularly sensitize users to best practices.

‍

Security breaches in software and operating systems

A second category of security breaches is found in the applications themselves.

‍

Software that is no longer maintained by its publisher, for example, does not benefit from updates to protect it against possible attacks.

‍

The same goes for operating systems, which must be updated as soon as their publisher asks for it.

‍

The solution: a fine management and monitoring of software installed and used throughout the company.

To note: the _Rzilient platform greatly facilitates this work of mapping the software environment and automatically carries out updates.

‍

Sophisticated cyberattacks

The last category of computer breaches: cyberattacks of a more advanced technical level.

Examples include denial of service (DDoS) attacks, the use of ransomware, etc.

‍

In the event of such an attack, it is necessary to call on cybersecurity experts in order to react quickly and effectively, and thus contain the attack.

‍

The solution? Develop advanced cybersecurity skills on your team (which can be very expensive), or be supported by an outsourcing solution, such as _rzilient, where skills are present.

‍

Cybersecurity best practices

Here are some best practices that you can implement, right now in your business, in order to increase your level of protection against computer attacks:

‍

1. Choose complex and unique passwords,
2. Update your software and operating systems regularly,
3. Avoid clicking on suspicious links or downloading suspicious files,
4. Use security tools adapted to your needs.

‍

Conclusion: cybersecurity can't wait any longer

Protecting your IT systems may seem like an “additional constraint” in the fast-paced life of entrepreneurship.

But given the real and growing risks associated with an attack, it is crucial to work in a structured way on cybersecurity in your company.

Continued efforts are required to ensure the security of your data and IT systems, and the experts at _rzilient are here to help.
