It is difficult to apply the latest security patch to various fixed function systems, such as Industrial Control Systems (ICS), Point of Sales (POS) Systems, KIOSKs, and ATMs, due to their sensitivity and outdated OS. This leaves them vulnerable to malware infection. As such these systems are placed in air-gapped network or low bandwidth network environments, which are designed to perform only set processes with bare minimum system requirements, it is often impossible to perform engine updates, real-time detection, and remediation with security programs built for PC environment. AhnLab Xcanner enables users to set scan and repair options according to each operating environment and provides minimal clashes with pre-installed security agents. Due to its user-friendly interface, on-site workers and facility managers with zero security knowledge can also easily respond to malware.
