Phishing, ransomware, unpatched flaws: most incidents can be prevented by a few simple measures, applied rigorously.
Cyberattacks no longer target only large companies: government bodies, banks, healthcare facilities, NGOs and SMEs are now regular targets. The good news is that most incidents exploit known weaknesses. A few basic measures, applied rigorously, greatly reduce the risk.
The 7 priority measures
- Enable multi-factor authentication on email, remote access (VPN) and all administrator accounts. A stolen password is then no longer enough to get in.
- Apply updates quickly: operating systems, applications, network equipment and web servers. Recent news is a reminder, with the PHP2Shell flaws exploited as soon as the fixes were published.
- Back up regularly, keeping at least one copy offline or isolated from the network, and test your restores. A backup that has never been tested is not a guarantee.
- Restrict administrator rights to what is strictly necessary: each user should only have the access they need for their work.
- Segment the network: separate guests, workstations, servers and sensitive equipment so that an intrusion cannot spread across the whole system.
- Train your staff to recognise phishing and unusual requests, which remain attackers' main way in.
- Prepare an incident response plan: who to alert, which systems to isolate, how to communicate and how to restart. On the day of an attack, every minute counts.
Where to start?
A security audit identifies your most critical vulnerabilities and prioritises actions by impact and cost. It is often complemented by penetration tests, always carried out with the written consent of the organisation concerned.
