一、前言
本人结合网上资料和个人的实践，利用一个下午的时间写出了这个适用于资源下载型网站的典型配置。这种配置的web网站初步实现了ip线程和线程流量的管理，同时proftpd用于上传资源，ssh用于主机管理。无疑这样可以自己支配宝贵的网络带宽，文章后面有个简单的防火墙配置仅供参考，我用的linux版本是redhat as 3.0。希望大家在看了这......

in this article i will explain how to make your linux box secure by taking basic security measures. this article will enable anybody to tighten the security of a redhat linux box.
bios security
always set a password on bios to disallow booting from floppy by changing the bios settings. this will block undesired people from trying to boot your linux system with a special boot disk and will protect you from people trying to change bios feature like allowing boot from floppy drive or booting the server without password prompt.
lilo security
add the three parameters in "/etc/lilo.conf" file i.e. time-out, restricted and password. these options will ask for password if boot time options (such as "linux single") are passed to the boot loader.
step 1
edit the lilo.conf file (vi /etc/lilo.conf) and add or change the three options :
boot=/dev/hda
map=/boot/map
install=/boot/boot.b
time-out=00 #change this line to 00
prompt
default=linux
restricted #add this line
password=<password> #add this line and put your password
image=/boot/vmlinuz-2.2.14-12
label=linux
initrd=/boot/initrd-2.2.14-12.img
root=/dev/hda6
read-only
step 2
the "/etc/lilo.conf" file should be readable by only root because it contains unencrypted passwords.
[root@kapil /]# chmod 600 /etc/lilo.conf (will be no longer world readable).
step 3
update your configuration file "/etc/lilo.conf" for the change to take effect.
[root@kapil /]# /sbin/lilo -v (to update the lilo.conf file).
step 4
one more security measure you can take to secure the "/etc/lilo.conf" file is to set it immutable, using the chattr command.
* to set the file immutable simply, use the command:
[root@kapil /]# chattr +i /etc/lilo.conf
this will prevent any changes (accidental or otherwise) to the "lilo.conf" file.
for more information about lilo security, read my article on lilo.
disable all special accounts
you should delete all default users and group accounts that you dont use on your system like lp, sync, shutdown, halt, news, uucp, operator, games, gopher etc
to delete a user account :
[root@kapil /]# userdel lp
to delete a group:
[root@kapil /]# groupdel lp
choose a right password
you should follow the following guidelines before choosing the right password.
