See man
sshd_config in general, but specifically the parts on the Port and PermitRootLogin.
See man
sudoers for the configuration of sudo
See man
iptables on how to block ICMP_ECHO_REQUESTS and put limits on the allowed source IPs
Alternatively, you can disable pings by setting /proc/sys/net/ipv4/icmp_echo_ignore_all to 1
For all other help: please be more specific on your task and what exactly you are stuck with.

MAN(1) General Commands Manual MAN(1)
NAME
man, lookman - print or find pages of this manual
SYNOPSIS
man [ option ... ] [ section ... ] title ...
lookman key ...
DESCRIPTION
Man locates and prints pages of this manual named title in the specified sections. Title is given in lower case. Each section is a num-
ber; pages marked (2S), for example, belong to chapter 2. If no section is specified, pages in all sections are printed. Any name from
the NAME section at the top of the page will serve as a title.
The options are:
-p Run proof(1) on the specified man pages.
-t Run troff and send its output to standard output.
-n (Default) Print the pages on the standard output using nroff.
Lookman prints the names of all manual sections that contain all of the key words given on the command line.
FILES
/sys/man/?/*
troff source for manual; this page is /sys/man/1/man
/sys/man/?/INDEX
indices searched to find pages corresponding to titles
/sys/lib/man/secindex
command to make an index for a given section
/sys/lib/man/lookman/index
index for lookman
SOURCE
/rc/bin/man
/rc/bin/lookman
SEE ALSO
proof(1)
BUGS
The manual was intended to be typeset; some detail is sacrificed on text terminals.
There is no automatic mechanism to keep the indices up to date.
Except for special cases, it doesn't recognize things that should be run through tbl and/or eqn.
