QNAP officially announced the release of the new version of the operating system QTS 5.2 for network data storage facilities (NAS). One of the key innovations was the Security Center, which ensures file activity monitoring and protection against malicious programs.
The Security Center feature allows users to automatically switch volumes to “Reading” mode if suspicious activity is detected, preventing file changes. Users can also create backup volumes to restore data if necessary and suspend creation schedules to avoid storage overflow with image files.
QNAP representatives explained that the Security Center actively monitors file actions to provide advanced data protection. When suspicious behavior is identified, the system takes swift protective actions such as creating backups or blocking, reducing risks and preventing data loss from cyber threats or user errors.
In addition to enhanced protection features, the updated QTS version also includes improvements like a 30% increase in NAS device startup and shutdown speeds. Support for self-encrypting drives TCG-RUBY (SED) has been added, along with the ability to create backups and restore Windows, discs, folders, and files on QNAP devices using the Netbak PC AGENT utility system.
NAS devices are common targets for cyber attacks due to the sensitive data they store and backup. Over the years, QNAP has faced security vulnerabilities from attacks like Deadbolt, Checkmate, and Ech0raix, which exploit weaknesses in connected devices.
QNAP regularly warns users about risks like Buborsataki attacks on NAS devices connected to networks, which often result in ransomware attacks. To mitigate these threats, QNAP recommends measures such as reducing router ports, disabling UPNP function on NAS devices, changing default port numbers, and disabling SSH and Telnet connections. Users are also advised to enable IP address and account access protection and change default passwords to enhance security.
