It is quite old and should not be considered for new deployments. That was the next to the last in a release series that started even longer ago. I am going to answer these question in terms broadly because the ultimate answer depends on what you are asking. There is no need for antimalware as RTEMS does not support loading executables at run-time. It is a single process (in the POSIX) sense embedded RTOS. Dynamic loading was only added in recent years and even then, it is an optional feature that is likely to not be used. On most deployments, there is no way to insert an executable or object code at run-time. Certainly not with any version this old. RTEMS can be, and often is, deployed without a network stack at all. Often the hardware targets do not include network hardware. The network stack included with 4.6 is now considered legacy and looking at the source, it looks to have included the ip_fw.c file which implements an IP packet firewall. So it at least has the possibility of having had one at that time. The current RTEMS TCP/IP stack tracks the latest releases from FreeBSD and does include those capabilities. If you are asking about writing an RTEMS application that is a firewall to scan content that crosses , then that could be constructed but you would have to port the malware scanner. The more I wrote, the more questions I had. I feel like I don't know the real intended goal. Is this an Information Assurance question for a deployed RTEMS application or a "can I build this with RTEMS as the RTOS" question?
