Hierarchical control of signature refers to the security control of deb packages, binary and script programs during installation and operation, so as to avoid damage to system security caused by programs with unknown sources or viruses.

The hierarchical control of signature includes two levels. Level 1 is “Allow only signed apps”, which means that there is security control over the installation of deb packages and the running of binary and script programs. Level 2 is “Allow any apps”, which means that there is no control over the installation of deb packages and the running of binary and script programs, that is, applications from any source can be installed/executed in the system.

We would like to remind you that you should carefully select “Allow any apps”. If you allow applications from any source to be installed and run in the system, it may cause system security to be damaged, user data to be stolen, core software components to be replaced and tampered with, and system root permission to be arbitrarily extracted. You shall bear all consequences caused by the above choice, including but not limited to direct or indirect personal losses, loss of business profits, trade interruption, loss of business information or any other economic losses, for which UnionTech Software shall not assume any liability.
