As far as I know FreeBSD supports the 4.4BSD concept of running the system in a definite security level to protect special files against modification etc. `sysctl -a' shows that the system by default runs in level `-1' which means `always insecure'. So how should I increase the security level for example to `1' (= secure) in multi-user mode and to `0' in single-user mode? Can it simply be done with `sysctl' or will this raise some difficulties in standard multi-user mode (apart from the fact that the kernel might only be replaced and the system log might only be truncated in single-user mode)? Thanks for any information! Konrad Heuer, GWDG, Goettingen, Germany (kheuer@gwdu60.gwdg.de)
