日志数据安全审计 syslog和SNMP 在使用SNMP方式获取日志数据时，需要确保设备上已经启用了SNMP代理，并配置了相应的OID和MIB以获取日志数据。在实际部署中，应采取相应的安全措施，如使用安全的SNMP版本（如SNMPv3）并配置合适的身份验证和加密选项，以保护日志数据的机密性和完整性。在使用syslog传输敏感信息时，应采取额外的安全措施，如使用虚拟专用网络（VPN）或使用加密的syslog协议（如Syslog over SSL/TLS）来确保日志数据的机密性和完整性。消息内容：具体的日志信息，描述了事件或错误的详细内容。阅读详情

日志审计

安恒日志审计为例

很多单位都需日志审计功能，因此Linux系统要配置syslg功能，Windows要配置agent，实现对操作系统的日志审计。

Linux配置syslog进行日志审计
配置路径：/etc/rsyslog.conf
在配置文件最后一行增加一条命令：* . *@IP地址：514
配置完成后需要重启rsyslog服务们就可以在日志审计页面查看到对应的系统。

[root@localhost ~]# vim /etc/rsyslog.conf 

  1 # rsyslog configuration file
  2 
  3 # For more information see /usr/share/doc/rsyslog-*/rsyslog_conf.html
  4 # If you experience problems, see http://www.rsyslog.com/doc/troubleshoot.html
  5 
  6 #### MODULES ####
  7 
  8 # The imjournal module bellow is now used as a message source instead of imuxsock.
  9 $ModLoad imuxsock # provides support for local system logging (e.g. via logger command)
 10 $ModLoad imjournal # provides access to the systemd journal
 11 #$ModLoad imklog # reads kernel messages (the same are read from journald)
 12 #$ModLoad immark  # provides --MARK-- message capability
 13 
 14 # Provides UDP syslog reception
 15 #$ModLoad imudp
 16 #$UDPServerRun 514
 17 
 18 # Provides TCP syslog reception
 19 #$ModLoad imtcp
 20 #$InputTCPServerRun 514
 21 
 22 
 23 #### GLOBAL DIRECTIVES ####
 24 
 25 # Where to place auxiliary files
 26 $WorkDirectory /var/lib/rsyslog
 27 
 28 # Use default timestamp format
 29 $ActionFileDefaultTemplate RSYSLOG_TraditionalFileFormat
 30 
 31 # File syncing capability is disabled by default. This feature is usually not required,
 32 # not useful and an extreme performance hit
 33 #$ActionFileEnableSync on
 34 
 35 # Include all config files in /etc/rsyslog.d/
 36 $IncludeConfig /etc/rsyslog.d/*.conf
 37 
 38 # Turn off message reception via local log socket;
 39 # local messages are retrieved through imjournal now.
 40 $OmitLocalLogging on
 41 
 42 # File to store the position in the journal
 43 $IMJournalStateFile imjournal.state
 44 
 45 
 46 #### RULES ####

在这里插入图片描述

Windows需要安装agent
安装包解压后有两个文件分别nxlog.conf和nxlog-ce-2.10.2150.msi。
执行*.msi后按照默认安装，安装完成后需要。
替换文件路径是C:\Program Files (x86)\nxlog\conf 。
修改刚刚替换的conf文件。在 < Output out > 中的内容更改为日志审计服务器地址
修改完成后要nxlog-ce程序服务重启在控制面板-＞管理工具–＞服务中，找到nxlog服
务，点击右键启动nxlog服务注意：若修改过nxlog.conf，需要在重启nxlog服务使配置生效

## This is a sample configuration file. See the nxlog reference manual about the
## configuration options. It should be installed locally and is also available
## online at http://nxlog.org/docs/

## Please set the ROOT to the folder your nxlog was installed into,
## otherwise it will not start.
