In a context where cyber-security incidents are becoming increasingly frequent and sophisticated, it is important to protect all confidential company data, especially that relating to IT infrastructure (all the hardware, software, networks and services that enable IT systems to function properly). Implementing proactive measures will protect this infrastructure and ensure rapid restoration of company operations in the event of a cyber-attack.
- Regularly update software and operating systems
This will enable vulnerabilities that could be exploited by cybercriminals to be corrected. These updates can often be automated.
- Control employee access to sensitive information.
This will prevent internal leakage of confidential data through human error. Each employee should have access only to those services required for his or her job, by implementing access controls.
- Use strong passwords
By prioritizing short, easy-to-remember phrases, for example, these will be more complex to guess, but easier to remember. To this, we recommend adding multi-factor authentication (MFA), which requires more than one confirmation to validate access to certain accounts or websites.
- Secure your network with firewalls
Firewalls allow you to filter incoming and outgoing traffic, while using virtual private networks (VPNs) to secure connections when employees are in the office or telecommuting. Firewalls also incorporate advanced Intrusion Detection and Prevention (IDS/IPS) functionality, which analyzes network packets in depth to identify known malicious signatures.
- Save and store important data
This enables all users to access a copy of their data in the event of loss. Ideally, these copies are stored offline or in the cloud.
- Employee training and awareness
Risks such as phishing and malware are high. By training them in good security practices, they will be less vulnerable to intrusion attempts.
- Draw up an incident response plan
In the event of an intrusion, this plan can minimize damage and facilitate a return to normal. Make sure all team members know the steps to follow.
- Collaborate with cybersecurity experts
If you don’t have the necessary in-house resources, experts can carry out audits, propose solutions tailored to your business and help you stay compliant with current regulations.
Securing your SME’s IT infrastructure is not an insurmountable task, but it does require a comprehensive approach combining technology and best practices. By implementing these measures, you strengthen your company’s security and reduce the risk of cyber-attacks.
