Cybersecurity threats in 2024 are becoming increasingly sophisticated. Ransomware attacks, phishing and insider errors remain the top threats for businesses across the Baltics. Here are concrete steps to strengthen your IT infrastructure protection.
1. Multi-Factor Authentication (MFA)
MFA is one of the most effective ways to prevent unauthorized access. Even if an attacker has your password, without the second factor they cannot log in. Enable MFA for all critical systems: email, VPN, cloud services and admin panels. Consider hardware keys (YubiKey) for privileged accounts.
2. Regular Security Updates
Over 60% of successful cyberattacks exploit known vulnerabilities for which patches already exist. Set up automatic updates for operating systems, applications and network equipment firmware. Use tools like unattended-upgrades on Ubuntu or yum-cron on RHEL systems.
3. Employee Security Training
Most attacks start with phishing. Conduct regular security trainings, run simulated phishing campaigns and create a culture where employees can safely report suspicious activity without fear of blame. Track metrics: click rate, report rate, repeat offenders.
4. Robust Backup Strategy
Follow the 3-2-1 rule: 3 copies of data, on 2 different media types, with 1 stored offsite. Test recovery quarterly — a backup that has never been restored is not a backup. Use immutable storage to protect against ransomware that targets backups.
5. Network Segmentation
Divide your network into zones: production servers, workstations, guests, IoT devices. VLAN segmentation limits the blast radius if one segment is compromised. Zero-trust principles mean every connection must be authenticated and authorized, even internal ones.
6. Log Monitoring and SIEM
Deploy centralized log management. Review failed login attempts, unusual outbound connections and privilege escalation events. Even a basic ELK stack or Graylog instance dramatically improves your incident detection capability.
Conclusion
IT security is not a one-time project, but a continuous process. E24 BALTIC helps companies in the Baltics build a reliable security system — from initial audit to implementation and 24/7 monitoring. Contact us for a free security assessment of your infrastructure.
