Industrial Control Systems (ICS) are increasingly under attack. Initially designed when Operational Technology (OT) networks were analog, monolithic, and proprietary systems with little to no connectivity to the outside world, security resulted from their relative isolation.
Technological evolution within the ICS environment introduced a security threat. ICS systems have become visible to hackers allowing them to exploit the security vulnerabilities within their environment.
Vulnerabilities in ICS
Legacy operating systems: ICS managing critical infrastructure cannot afford unexpected outages, even for maintenance or basic update patching, leaving the Windows based terminals vulnerable and exposed to attacks.
Terminals, controllers, and protocols do not have security designed into them: The serial protocols of ICS systems do not have authentication or encryption features. Once connected to the corporate network, ICS systems are exposed to the same potential cyber threats as the rest of the network.
The lack of visibility
The absence of forensics, information and event management systems, make it difficult to detect anomalies or signals within the environment that are precursors to attacks.
Enterprise firewall solution
The Enterprise Firewall Solution is designed to address the broad spectrum of security requirements and issues across an organization’s network environment. The solution can be complemented with different technologies (e.g. wireless, sandboxing, etc.), services, and tools, extending the FortiGate’s service delivery and functions beyond traditional firewalling.
Secure access solution
Depending on the deployment mode, Fortinet’s Secure Access solution can complement an Enterprise Firewall deployment to cover an organization’s wireless requirements.
Advanced threat protection (ATP)
Advanced Threat Protection can complement Enterprise Firewall deployments to provide in depth threat prevention, detection, and mitigation.
FortiAnalyzer is a network security logging, analysis and reporting appliance which aggregates log data from all Fortinet security appliances.
FortiManager delivers the versatility required to effectively manage a Fortinet-based security infrastructure with centralized policy management, analytics and reporting.
