Cybersecurity, or computer security, represents the entire process and actions to protect computers, servers, networks or all data stored by a company from malicious attacks.   More than a third of companies have reportedly already been victims of cyber-attacks.  These attacks often have serious consequences for companies.  Even if they do not always prevent the worst, some preventive measures are essential. Here are some points to follow to prevent this type of attack:

1. Update all devices as soon as possible.

Cyber criminals are looking every day to find the loophole that would allow them to penetrate information systems. Software providers regularly identify weaknesses in their systems and make them public by publishing updates. It is therefore important to keep your entire operating system and software up to date. Updates make it possible to increase the level of security of all the information systems of a company.

2. Control and limit the access points to computer systems

Teleworking and computer security

Controlling the access points to information systems is essential for optimal security.  Restricting computer access to certain users allows the implementation of an effective privacy policy.  Indeed, new ways of working such as teleworking or frequent travel increase the risks by increasing the number of external accesses to a single company’s information systems.

3. Comply with regulations and recommendations

In order to protect themselves as effectively as possible, companies must adopt information systems security policy.  This makes possible to establish a clear framework and rules for companies’ IT equipment. It also provides a framework for the use of information systems by employees.  Some dedicated National Organisation, implemented a number of recommendations to help and support companies in the implementation of preventive measures. For example, recommendations on passwords or website security. This helps to avoid simple mistakes.

4. Train collaborators to good practices

A single negligence on the part of an employee can lead to a cyber-attack. The proper use of information systems and the fight against cybercrime is a shared task by all employees of a company. Awareness and training is a major step in the implementation of a cyber security policy. This step highlights the rights and duties of each employee. Cybersecurity must be part of everyone’s daily life through simple but essential reflexes for the proper functioning of systems and the durability of the company’s data.

5. Perform a regular backup of your data

In order to deal with excessive damage following a cyber-attack, it is important to make a regular backup of all company data.  Each employee must backup all his data every week, on an external device every week.  It is also advisable to double this weekly backup with a daily backup on the device of your choice. This will prevent the loss of all data in case of attack or data destruction.

In conclusion, cyber-crime is now a permanent threat to companies and organizations. Means to fight this form of crime are put in place by dedicated organisations, but collective awareness within teams is necessary to maintain maximum vigilance and avoid simple mistakes that can quickly be fatal and cause serious damage.
