没有永远的安全，如何在被攻击的情况下，快速响应和快速溯源分析攻击动作是个重要的话题。想要分析攻击者做了什么、怎么攻击进来的、还攻击了谁，那么日志是必不可少的一项，因此我们需要尽可能采集多的日志来进行分析攻击者的动作，甚至在攻击者刚落脚的时候就阻断攻击者。
这边根据官方文档：https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html 使用Docker安装了Elastic和Kibana
# 安装es
docker network create elastic
docker pull docker.elastic.co/elasticsearch/elasticsearch:8.12.1
docker run --name es01 --net elastic -p 9200:9200 -it -m 1GB docker.elastic.co/elasticsearch/elasticsearch:8.12.1
# 记录es的密码和注册kibana所需要的token
# 测试es是否正确运行
export ELASTIC_PASSWORD="es_your_password"
docker cp es01:/usr/share/elasticsearch/config/certs/http_ca.crt .
curl --cacert http_ca.crt -u elastic:$ELASTIC_PASSWORD https://localhost:9200
# 安装kibana
docker pull docker.elastic.co/kibana/kibana:8.12.1
docker run --name kib01 --net elastic -p 5601:5601 docker.elastic.co/kibana/kibana:8.12.1
会给出kibana的注册地址，访问填入上述记录的token即可。
不知道是机器性能问题还是Docker安装的问题，es容器经常会挂掉。
根据https://www.elastic.co/guide/en/elasticsearch/reference/current/rpm.html、https://www.elastic.co/guide/en/kibana/current/rpm.html官方文档，可以yum install安装。因为公司访问镜像源被封，因此使用上述文档中下载rpm安装：
# 安装es
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.12.1-x86_64.rpm
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.12.1-x86_64.rpm.sha512
shasum -a 512 -c elasticsearch-8.12.1-x86_64.rpm.sha512
sudo rpm --install elasticsearch-8.12.1-x86_64.rpm
安装kibana
wget https://artifacts.elastic.co/downloads/kibana/kibana-8.12.1-x86_64.rpm
wget https://artifacts.elastic.co/downloads/kibana/kibana-8.12.1-x86_64.rpm.sha512
shasum -a 512 -c kibana-8.12.1-x86_64.rpm.sha512
sudo rpm --install kibana-8.12.1-x86_64.rpm依然在安装es的rpm时，会吐出es/kibana的密码：
The generated password for the elastic built-in superuser is : Fq*S7jxCjFfPu6nN8NG8es服务可能启动不了，但是安装时会给出启动命令：
sudo systemctl daemon-reload
sudo systemctl enable elasticsearch.service测试es启动是否正常：
export ELASTIC_PASSWORD="Fq*S7jxCjFfPu6nN8NG8"
curl --cacert /etc/elasticsearch/certs/http_ca.crt -u elastic:$ELASTIC_PASSWORD https://localhost:9200记得改下配置文件，使其监听在0.0.0.0上面：
# /etc/elasticsearch/elasticsearch.yml
# Allow HTTP API connections from anywhere
# Connections are encrypted and require user authentication
http.host: 0.0.0.0
# Allow other nodes to join the cluster from anywhere
# Connections are encrypted and mutually authenticated
transport.host: 0.0.0.0kibana一样，记得改下配置文件，使其监听在0.0.0.0上面：
# /etc/kibana/kibana.yml
server.host: "0.0.0.0"在Kibana上，Management->Fleet->Add Fleet Server，先安装Fleet Server，URL填写https协议，端口可以填默认的8220。装好Fleet Server后再装Elastic Agent，Fleet Server也是一个Agent，因此不能在同一台机器上同时装Fleet Server和Elastic Agent。
为了使其Elastic Agent附带Security能力，可以添加各式各样的integrations集成，如到Security->Manage->Get started->Add security integrations安装安全集成：
注意，如果有如下错误需解决，否则会无法查阅规则：
有些规则没开，记得开下，比如我把reverse shell规则打开后：Security->Dashboards->Detection & Response可以看到一些概览：
Windows事件管理器日志不是单纯的文本，因此需要借助一些工具来帮助我们完成采集的目的。这里使用winlogbeat（https://www.elastic.co/cn/beats/winlogbeat）完成。官方提供了很详细的安装文档（https://www.elastic.co/guide/en/beats/winlogbeat/current/winlogbeat-installation-configuration.html），核心就是配置想要记录的日志类型和对外传输的方案，这里我使用的方案为：
记录的日志类型，我没改，默认就是Security、Application，甚至还有Sysmon
对外传输，我使用了传输到elastic
配置好winlogbeat.yml后可以进行测试配置文件对不对：
.\winlogbeat.exe test config -c .\winlogbeat.yml -e下面为我的配置文件信息：
###################### Winlogbeat Configuration Example ########################
# This file is an example configuration file highlighting only the most common
# options. The winlogbeat.reference.yml file from the same directory contains

# transaction published.
#tags: ["service-X", "web-tier"]
# Optional fields that you can specify to add additional information to the
# output.

# the dashboards is disabled by default and can be enabled either by setting the
# options here or by using the `setup` command.
#setup.dashboards.enabled: false
# The URL from where to download the dashboard archive. By default, this URL
# has a value that is computed based on the Beat name and version. For released
# versions, this URL points to the dashboard archive on the artifacts.elastic.co
# website.
#setup.dashboards.url:
# =================================== Kibana ===================================
# Starting with Beats version 6.0.0, the dashboards are loaded via the Kibana API.
# This requires a Kibana endpoint configuration.
setup.kibana:
# Kibana Host
# Scheme and port can be left out and will be set to the default (http and 5601)
# In case you specify and additional path, the scheme is required: http://localhost:5601/path
# IPv6 addresses should always be defined as: https://[2001:db8::1]:5601
#host: "localhost:5601"
# Kibana Space ID
# ID of the Kibana Space into which the dashboards should be loaded. By default,
# the Default Space will be used.
#space.id:
# =============================== Elastic Cloud ================================
# These settings simplify using Winlogbeat with the Elastic Cloud (https://cloud.elastic.co/).
# The cloud.id setting overwrites the `output.elasticsearch.hosts` and
# `setup.kibana.host` options.
# You can find the `cloud.id` in the Elastic Cloud web UI.
#cloud.id:
# The cloud.auth setting overwrites the `output.elasticsearch.username` and
# `output.elasticsearch.password` settings. The format is `<user>:<pass>`.
#cloud.auth:

# ================================== Logging ===================================
# Sets log level. The default log level is info.
# Available log levels are: error, warning, info, debug
#logging.level: debug
# At debug level, you can selectively enable logging only for some components.
# To enable all selectors, use ["*"]. Examples of other selectors are "beat",
# "publisher", "service".
#logging.selectors: ["*"]
# ============================= X-Pack Monitoring ==============================
# Winlogbeat can export internal metrics to a central Elasticsearch monitoring
# cluster. This requires xpack monitoring to be enabled in Elasticsearch. The
# reporting is disabled by default.
# Set to true to enable the monitoring reporter.
#monitoring.enabled: false
# Sets the UUID of the Elasticsearch cluster under which monitoring data for this
# Winlogbeat instance will appear in the Stack Monitoring UI. If output.elasticsearch
# is enabled, the UUID is derived from the Elasticsearch cluster referenced by output.elasticsearch.
#monitoring.cluster_uuid:
# Uncomment to send the metrics to Elasticsearch. Most settings from the
# Elasticsearch outputs are accepted here as well.
# Note that the settings should point to your Elasticsearch *monitoring* cluster.
# Any setting that is not set is automatically inherited from the Elasticsearch
# output configuration, so if you have the Elasticsearch output configured such
# that it is pointing to your Elasticsearch monitoring cluster, you can simply
# uncomment the following line.
#monitoring.elasticsearch:
# ============================== Instrumentation ===============================
# Instrumentation support for the winlogbeat.
#instrumentation:
# Set to true to enable instrumentation of winlogbeat.
#enabled: false

# ================================= Migration ==================================
# This allows to enable 6.7 migration aliases
#migration.6_to_7.enabled: true
这时候，可能elastic上面搜不到数据，是因为winlogbeat使用了他自己的索引，默认为winlogbeat-version，笔者测试时，发现kibana上迟迟出现不了该索引，还以为数据传输没成功呢，因此通过如下手段进行排查，先获取es上面的索引信息：
http://your_ip:9200/_cat/indices?v发现有类似winlogbeat的索引信息：
yellow open .ds-winlogbeat-8.12.0-2024.02.03-000001 UpWhWCpdR-2WgMVe_kiH9A 1 1 192705 0 131.1mb 131.1mb
后面尝试在kibana上创建一个新的索引即可，v7.17.12版本的kibana创建索引的过程如下：discover->选项->View Discover settings
找到“索引模式”创建一个新的索引即可：
这时候就可以检索事件管理器日志了：
