apache学习安全总结

1、安全优化（此项为防止别人看到目录结构）
[root@python htdocs]# ls
wolf.html
[root@python htdocs]# mv wolf.html laolang.html


[root@python conf]# vi httpd.conf
下面这段去掉Indexes或者-Indexes
 
    Options Indexes FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all

网页打开能看到目录结构，所以把Indexes 去掉，此时报403错误(这是就需要修改为指定目录，虚拟主机里面有具体配置)
192.168.3.41 - - [03/Nov/2016:23:32:13 +0800] "GET / HTTP/1.1" 403 202
192.168.3.41 - - [03/Nov/2016:23:32:13 +0800] "GET / HTTP/1.1" 403 202
2、隐藏版本号
[root@python extra]# vi httpd-default.conf
把Full改为Prod


# ServerTokens
# This directive configures what you return as the Server HTTP response
# Header. The default is 'Full' which sends information about the OS-Type
# and compiled in modules.
# Set to one of:  Full | OS | Minor | Minimal | Major | Prod
# where Full conveys the most information, and Prod the least.
#
ServerTokens Prod


主配置文件里启用
# Various default settings
Include conf/extra/httpd-default.conf

[root@python conf]# 
3、隐藏版本 （源码中改，然后才configure make make install）
[root@python include]# pwd
/soft/apache/include
[root@python include]# cat ap_release.h 


#define AP_SERVER_BASEVENDOR "Apache Software Foundation"
#define AP_SERVER_BASEPROJECT "Apache HTTP Server"
#define AP_SERVER_BASEPRODUCT "Apache"


#define AP_SERVER_MAJORVERSION_NUMBER 2
#define AP_SERVER_MINORVERSION_NUMBER 2
#define AP_SERVER_PATCHLEVEL_NUMBER   31
#define AP_SERVER_DEVBUILD_BOOLEAN    0


[root@python include]# cat os.h
#define PLATFORM "Unix"
