       Recommended compiler and linker flags for GCC for security purpose from Red Hat and Fedora Linux https://developers.redhat.com/blog/2018/03/21/compiler-and-linker-flags-gcc These should work on other Linux distro too including Unix-like system when you use the GCC.  #infosec #security #linux #sysadmin

       @nixCraft last time I heard debugging information in production binaries should be removed because some malware uses it to calculate addresses it needs. Do you know why it’s not the case in this recommendation?

       @hexorg @nixCraft You can strip it afterwards and still then use it for your advantage when some dump appears.
