社区安全能力建设，长亭科技雷池 Web 应用防火墙 官网 https://waf-ce.chaitin.cn/介绍 雷池（SafeLine WAF）Web应用防火墙由长亭科技出品，其核心检测能力由智能语义分析算法驱动，对0day具有一定的天然免疫能力。便捷性：采用容器化部署，一条命令即可完成安装，0 成本上手；安全配置开箱即用，无需人工维护，可实现安全躺平式管理安全性：首创业内领先的智能语义分析算法，精准检测、低误报、难绕过；语义分析算法无规则，面对未知特征的 0day 攻击不再手足无措高性能：无规则引擎，线性安全检测算法，平均请求检测延迟在 1 毫秒级别；并发能力强，单核轻松检测 2000+ TPS，只要硬件足够强，可支撑的流量规模无上限高可用：流量处理引擎基于 Nginx 开发，性能与稳定性均可得到保障；内置完善的健康检查机制，服务可用性高达 99.99%部署情况 我司使用某国产OA系统，该OA系统在近一年中，几乎每月都会出现一到两次“高危级”漏洞，为了在0day出现到修复前的真空期进行安全防御，我司对Web应用防火墙进行了考察； 市面上绝大部分WAF都是基于规则进行命中，在此领域黑客对抗激烈，社区经常出现针对某WAF的规则绕过教程，并且基于规则的WAF几乎无法对0day进行防御，而基于AI机器学习的WAF误报严重，常常会造成OA访问中断；在一段时间测试后，最终选择了雷池 Web 应用防火墙。 在2023年4月23日对雷池进行测试，并对误拦截进行处理；在2023年5月24日对雷池进行正式切换，此时版本为1.5.1。里程碑记录 在部署后的6月份，我司OA出现了前台SQL注入漏洞，7月份出现了文件上传漏洞、XXE漏洞；而此漏洞均在雷池天然防护范围中，为漏洞修复真空期赢得了宝贵的时间。当前我司雷池累计访问量已近千万在系统漏洞修复真空期，日均拦截攻击独立IP两位数已加入IP 情报共享计划，共建社区安全雷池安装确保机器上正确安装 Docker 和 Compose V2docker info # >= 20.10.6 docker compose version # >= 2.0.0注意配置docker镜像加速以及docker网卡修改网段防止冲突部署安装运行mkdir -p /safeline && cd safeline # 下载并执行 setup bash -c "$(curl -fsSLk https://waf-ce.chaitin.cn/release/latest/setup.sh)"雷池升级自动一键更新 WARN: 雷池 SafeLine 服务会重启，流量会中断一小段时间，根据业务情况选择合适的时间来执行升级操作。 # 请到 compose.yaml 同级目录下执行下面脚本 cd /safeline | bash -c "$(curl -fsSLk https://waf-ce.chaitin.cn/release/latest/upgrade.sh)" #升级成功后, 可以执行以下命令删除旧版本 Docke 镜像, 以释放磁盘空间 docker rmi $(docker images | grep "safeline" | grep "none" | awk '{print $3}')最后一切，只为安全！

参加了2023年上半年软考 首先祝大家软考科科75分王工在今天参加了2023年上半年计算机技术与软件专业技术资格（水平）考试-中级-网络工程师考试，为了考试，总计学习时间约为3小时，泰酷啦上午都是选择题，感觉能得50分左右，题目还是难度适中，好好学问题就不大。中午没人请我吃发，小伙伴早上8点半才起床，9点考试，开车两个小时，现场也没有遇到粉丝，呜呜呜下午题有点难，软考的网络配置都是以华为为主，而且考了BGP，众所周知，王工只用华三和OSPF，所以下午考糊了，预计三十分左右我们考场抓到了两个作弊的，看网友反馈，今年肯定是发生了泄题，有完整的原题答案被搜出来了当然，考试已经结束了，无论通过与否，等出成绩，我会在贴出来，无论多少分。

0基础上手python编程，实践进程+URL守护程序+企业微信机器人告警 全民制作人大家好，我是学习python两天半的练习生王忘杰，喜欢路由交换、linux、网络安全，开整！这是我的第三篇0基础python文章，请大家支持，谢谢~开发思路用于监控指定的URL或进程，在我的场景中，使用了httpprinter打印机插件，这个程序提供了http接口的打印功能，当程序死机时，http接口无法连接，则需要重启程序设计思路很简单，访问失败发送告警并重启程序即可。绘制开发流程图使用python语言实现import os,requests,win32api,json,psutil def process_check(processname): #检查进程是否存在，存在返回1 pl = psutil.pids() for pid in pl: if psutil.Process(pid).name() == processname: return 1 else: return 0 def url_check(url): #检查URL try: r = requests.get(url, timeout=3, verify=False) if r.status_code == 200: print("运行中，无异常") else: msg = "http打印程序状态异常，重启程序" yun_push(msg) # 关闭程序 os.system("taskkill /F /IM HttpPrinter.exe") # 启动程序 win32api.ShellExecute(0,'open','C:\\HttpPrinter_latest\\HttpPrinter.exe','','',1) except: msg = "http打印程序状态异常，重启程序" yun_push(msg) # 关闭程序 os.system("taskkill /f /im HttpPrinter.exe") # 启动程序 win32api.ShellExecute(0,'open','C:\\HttpPrinter_latest\\HttpPrinter.exe','','',1) def yun_push(content): #企业微信推送 url = 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=用自己的' s = json.dumps({'msgtype': 'text', 'text': {"content": content}}) print(requests.post(url, data=s).text) if __name__ == '__main__': #检查进程是否存在 #if(process_check("HttpPrinter.exe")) #检查URL url_check("http://10.0.0.1:1234/")编译成EXE程序pyinstaller -F -w .\main.py部署windows计划任务运行效果

0基础上手python编程，实践URL监控+企业微信机器人告警 全民制作人大家好，我是学习python两天半的练习生王忘杰，喜欢路由交换、linux、网络安全，开整！这是我的第二篇0基础python文章，请大家支持，谢谢~开发思路用于监控指定的URL，在我的场景中，我是从腾讯VPS上监控公司宽带出口，当URL访问超时时，即为宽带故障。设计思路很简单，访问失败发送告警，访问成功发送恢复通知，同时要使用配置文件进行配置，防止持续重复告警。绘制开发流程图使用python语言实现#!/usr/bin/python3 import requests import time import json import os # 监测URL是否正常响应 def url_check(url): # 当前时间 check_time = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime()) try: # 请求URL， 设置3s超时， 忽略SSL证书 r = requests.get(url, timeout=3, verify=False) if r.status_code == 200: fo = open(config,"r") line = fo.read(1) print(line) #判断配置文件内容 if line == "1": print("发送报警") fo.close() fo = open(config, "w") fo.write('0') print("配置重置为0") # 请求响应状态 msg = "监控的URL：%s%sURL恢复状态正常：%s%s监测时间：%s" % ( url, "\n\n", r.status_code, "\n\n", check_time) # 推送消息 yun_push(msg) else: print("当前配置为",line) fo = open(config, "w") fo.write('0') print("配置重置为0") else: fo = open(config, "r") line = fo.read(1) print(line) if line == "1": print("退出程序") else: print("发送报警") fo.close() fo = open(config, "w") fo.write('1') print("配置重置为1") # 请求响应状态 msg = "监控的URL：%s%sURL访问异常：%s%s监测时间：%s" % ( url, "\n\n", r.status_code, "\n\n", check_time) # 推送消息 yun_push(msg) except: fo = open(config, "r") line = fo.read(1) print(line) if line == "1": print("退出程序") else: print("发送报警") fo.close() fo = open(config, "w") fo.write('1') print("配置重置为1") # 请求响应状态 msg = "监控的URL：%s%sURL访问失败，无法连接%s监测时间：%s" % ( url, "\n\n", "\n\n", check_time) # 推送消息 yun_push(msg) def yun_push(content): url = 'https://qyapi.weixin.qq.com/cgi-bin/webhook/send?key=用自己的' s = json.dumps({'msgtype': 'text', 'text': {"content" : content}}) print(requests.post(url, data=s).text) if __name__ == '__main__': #判断配置文件是否存在，不存在则生成配置文件并退出，配置文件则存在执行 config = './baidu.config' if not os.path.exists(config): print("配置文件不存在") file = open(config,'w') file.close() print("配置文件已生成") else: print("配置文件存在，执行URL检测") url_check("https://www.baidu.com/")运行效果正式使用在VPS部署python脚本，并设置定时任务即可

VMware企业虚拟化综合实验3 vSphere8超融合部署 介绍2022.08.30 VMware 宣布正式发布 VMware vSphere 8vSAN8.0 ESA要求25Gbps网络、VM认证的服务器和最低4块固态,ESA无需缓存盘.https://blogs.vmware.com/china/2022/09/23/vmware-vsan-esa-osa-%e5%8c%ba%e5%88%ab%e4%b8%8e%e9%80%89%e6%8b%a9/vSAN策略https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID-08911FD3-2462-4C1C-AE81-0D4DBC8F7990.html实验规划1、在vSphere7虚拟化平台上，以vSphere8为基础，部署4台全闪超融合。2、IP分配vcenter地址 172.16.10.220esxi1 172.16.10.221esxi2 172.16.10.222esxi3 172.16.10.223esxi4 172.16.10.2243、ESXi配置为 16C 64G 400G系统盘 1T闪存盘x34、因环境限制，仅配置单网卡5、因环境限制，无法部署vSAN ESA，仍然使用传统OSA模式，即每个磁盘组1块缓存盘6、因模拟环境限制，vCenter安装在外部主机上一、安装ESXi8配置虚拟机安装ESXi8配置IP地址并登录测试安装其他3台ESXi主机二、安装vCenter8通过windows发起安装vCenter配置vSAN时不需要先将ESXi接入vCenter三、配置vSAN集群按vSAN向导配置创建分布式交换机配置存储流量IP声明磁盘，将每个主机的第一块硬盘标记为缓存层，后两块标记为容量层。此时就遇到了vSphere全闪最大的问题，不滿足硬件的情况下，全闪也要标记缓存层因环境限制，将vSAN与管理都放置在同一网卡上运行此时vSAN自动配置完成四、消除vSAN告警查看vSAN当前告警SCSI控制器告警，无影响可消除因环境限制，配置到DSwitch-vSAN的网卡无法通讯，屏蔽此告警五、开启DRS和HA集群-配置-服务启动DRS启动HA六、调整vSAN存储策略默认为vSAN Default Storage Policy策略，默认策略详情可查看官网https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.vsan.doc/GUID-C228168F-6807-4C2A-9D74-E584CAF49A2A.html七、安装一台虚拟机上传镜像文件，注意vSAN仅能存储VMDK文件，镜像需放置在本地磁盘安装Centos7系统因环境限制，无法联网，无法安装vmtools八、在线迁移测试需为VMkernel适配器配置vMotion从222不停机迁移到224迁移完成九、HA vSAN测试ESXi4直接关机，测试Centos7是否自动拉起虚拟机自动在221重启vSAN进入故障状态，数据无丢失此时vSAN会根据策略进行空间收缩，在存活主机上重建数据，vSAN容量从8T收缩为6T十、剥离故障主机假设此主机无法修复，进行剔除剔除后故障消除十一、增加新主机为vSAN集群新增一台主机，横向扩展将主机加入DSwitch分布式交换机容量增加到8T十一、硬盘更换因环境限制无法直接模拟十二、硬盘新增（存在BUG，请勿使用）目标：移除一块硬盘，插入另一块硬盘，增加容量层空间缓存层无法直接更换容量层可以移除仅更换磁盘选择,视情况而定，若硬盘已经完全损坏，迁移磁盘可以能造成多次重试失败、主机卡顿移除完成vSAN容量下降为7T分离设备插入新硬盘后，标记磁盘为HDD与vSphere7不同，此处无法直接将硬盘添加至vSAN组临时处理措施，可以按新增服务器的方式操作。十三、vSAN集群关机、开机集群-vSAN-关闭集群预检查确认关机关机完成，作为vSAN集群，个人认为vCenter需要放在外部或者本地磁盘中，防止开机vSAN异常开机，开启ESXi，开启vCenter，全部启动完成后，选择重新启动vSAN集群耐心等待即可十四、小结整体与vSphere7变化不大，使用方式无异常，全闪模式对硬件有要求。
