Introduction: A Critical Alert for Virtualized Environments

Review Windows Event Logs

1. Missing Kernel Headers/Devel Packages: The Deep Security Anti-Malware driver is a kernel module. On Linux systems, if the kernel headers matching the current running kernel are not present, the driver cannot compile or install.
2. Incompatible Kernel Version: The operating system kernel has been updated to a version newer than what the current Deep Security Agent supports.
3. Secure Boot (UEFI): If Secure Boot is enabled in the BIOS, the operating system may block the loading of unsigned third-party kernel modules (like the Trend Micro AM driver).
4. GCC Compiler Issues: The driver compilation process requires the GNU Compiler Collection (GCC). If the version of GCC used to compile the kernel differs from the version installed on the system, compilation may fail.
5. File System Permissions: The account running the Deep Security Agent service may lack the necessary permissions to write to the module directories (e.g., /lib/modules).
