RTEMS 4.6.5 was released almost 13 years ago. 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
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
not with any version this old.
RTEMS can be, and often is, deployed without a network stack at all. Often
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
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
FreeBSD and does include those capabilities.
If you are asking about writing an RTEMS application that is a firewall to
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
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?
I hope this helps some..
