- Backup, Backup, Backup! In most cases, a fresh and secure backup of data can prevent ransomware attack from succeeding. For this reason, many attackers put in a lot of effort to find and encrypt backups. The best backup will be air-gapped, meaning physically disconnected from your main network. It is also important to have a regular backup schedule with robust security procedures.
- Install a Next-Gen Antivirus. Next generation anti-virus software combines a classic signature-based antivirus with powerful exploit protection, ransomware protection and endpoint detection and response (EDR). Mcafee, Fireeye, and Sentinel One are all examples of antivirus software with these features.
- Install a Next-Gen Firewall. A Next-Gen-Firewall is also called Unified threat management (UTM) firewall. It adds a layer of security at every entry and exit point of your company data communication. It combines classic network security with intrusion detection, intrusion prevention, gateway antivirus, email filtering and many other features.
If you can afford it, having staff or hiring a dedicated service to monitor network traffic can also help to detect unusual activity and prevent ransomware attacks. Ransomware attackers usually do a lot of surveillance on a network before attempting a hack. This “reconnaissance” phase has certain tell-tale signs. If you can catch these early, it’s possible to detect the attacker early and deny them access to the network.
If you get hit by ransomware, a professional ransomware response service can help to identify and patch security gaps.
