PowerShell 技能连载 - 容器编排管理

在容器编排领域，管理对于确保容器集群的稳定性和应用服务的可用性至关重要。本文将介绍如何使用PowerShell构建一个容器编排管理系统，包括集群监控、服务管理、资源调度等功能。

集群监控

首先，让我们创建一个用于监控容器集群的函数：

最佳实践

  1. 监控集群状态
  2. 管理服务部署
  3. 优化资源调度
  4. 保持详细的运行记录
  5. 定期进行集群检查
  6. 实施资源优化策略
  7. 建立预警机制
  8. 保持系统文档更新

PowerShell 技能连载 - Kubernetes 集成

在容器化时代，将PowerShell与Kubernetes集成可以为容器管理带来强大的自动化能力。本文将介绍如何使用PowerShell构建一个Kubernetes管理系统，包括集群管理、应用部署和监控分析等功能。

最佳实践

  1. 实施集群管理
  2. 部署应用服务
  3. 监控资源使用
  4. 保持详细的部署记录
  5. 定期进行健康检查
  6. 实施监控策略
  7. 建立告警机制
  8. 保持系统文档更新

PowerShell 技能连载 - 金融交易监控管理

在金融交易领域，监控管理对于确保交易安全性和合规性至关重要。本文将介绍如何使用PowerShell构建一个金融交易监控管理系统，包括交易监控、风险评估、合规检查等功能。

交易监控

首先，让我们创建一个用于监控金融交易的函数：

PowerShell 技能连载 - XML 数据处理技巧

在 PowerShell 中处理 XML 数据是一项常见任务，特别是在处理配置文件或与 Web 服务交互时。本文将介绍一些实用的 XML 处理技巧。

首先，让我们看看如何创建和读取 XML 数据：

# 创建 XML 文档
$xmlContent = @"
<?xml version="1.0" encoding="UTF-8"?>
<配置>
    <系统设置>
        <服务器>
            <名称>主服务器</名称>
            <IP地址>192.168.1.100</IP地址>
            <端口>8080</端口>
        </服务器>
        <数据库>
            <类型>MySQL</类型>
            <连接字符串>Server=localhost;Database=testdb;User=admin</连接字符串>
        </数据库>
    </系统设置>
    <用户列表>
        <用户>
            <ID>1</ID>
            <姓名>张三</姓名>
            <角色>管理员</角色>
        </用户>
        <用户>
            <ID>2</ID>
            <姓名>李四</姓名>
            <角色>普通用户</角色>
        </用户>
    </用户列表>
</配置>
"@

# 将 XML 字符串转换为 XML 对象
$xml = [xml]$xmlContent

# 访问 XML 数据
$serverName = $xml.配置.系统设置.服务器.名称
$dbType = $xml.配置.系统设置.数据库.类型
Write-Host "服务器名称：$serverName"
Write-Host "数据库类型：$dbType"

使用 XPath 查询 XML 数据：

1
2
3
4
5
6
7
8
9
10
11
12
# 使用 XPath 查询特定用户
$adminUser = $xml.SelectSingleNode("//用户[角色='管理员']")
Write-Host "`n管理员信息："
Write-Host "姓名：$($adminUser.姓名)"
Write-Host "ID：$($adminUser.ID)"

# 查询所有用户
$allUsers = $xml.SelectNodes("//用户")
Write-Host "`n所有用户列表："
foreach ($user in $allUsers) {
    Write-Host "姓名：$($user.姓名), 角色：$($user.角色)"
}

修改 XML 数据：

10
11
12
13
14
# 添加新用户
$newUser = $xml.CreateElement("用户")
$newUser.InnerXml = @"
    <ID>3</ID>
    <姓名>王五</姓名>
    <角色>普通用户</角色>
"@
$xml.配置.用户列表.AppendChild($newUser)

# 修改现有数据
$xml.配置.系统设置.服务器.端口 = "9090"

# 保存修改后的 XML
$xml.Save("config.xml")

处理 XML 属性：

# 创建带有属性的 XML
$xmlWithAttributes = @"
<?xml version="1.0" encoding="UTF-8"?>
<系统>
    <服务 名称="Web服务" 状态="运行中">
        <配置 版本="1.0" 环境="生产">
            <参数 类型="字符串">测试值</参数>
        </配置>
    </服务>
</系统>
"@

$xmlDoc = [xml]$xmlWithAttributes

# 访问属性
$serviceName = $xmlDoc.系统.服务.名称
$serviceStatus = $xmlDoc.系统.服务.状态
Write-Host "`n服务信息："
Write-Host "名称：$serviceName"
Write-Host "状态：$serviceStatus"

一些实用的 XML 处理技巧：

  1. 使用 XML 命名空间：

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    13
    $xmlWithNamespace = @"
    <?xml version="1.0" encoding="UTF-8"?>
    <ns:系统 xmlns:ns="http://example.com/ns">
        <ns:服务>测试服务</ns:服务>
    </ns:系统>
    "@

    $xmlNs = [xml]$xmlWithNamespace
    $nsManager = New-Object System.Xml.XmlNamespaceManager($xmlNs.NameTable)
    $nsManager.AddNamespace("ns", "http://example.com/ns")

    $service = $xmlNs.SelectSingleNode("//ns:服务", $nsManager)
    Write-Host "`n带命名空间的服务：$($service.InnerText)"

  2. 验证 XML 格式：

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    function Test-XmlFormat {
        param([string]$XmlString)
        try {
            [xml]$XmlString | Out-Null
            return $true
        }
        catch {
            return $false
        }
    }

  3. 处理大型 XML 文件：

    1
    2
    3
    4
    5
    6
    7
    8
    9
    10
    11
    12
    # 使用 XmlReader 处理大型 XML 文件
    $reader = [System.Xml.XmlReader]::Create("large-data.xml")
    while ($reader.Read()) {
        if ($reader.NodeType -eq [System.Xml.XmlNodeType]::Element) {
            if ($reader.Name -eq "用户") {
                $userXml = $reader.ReadOuterXml()
                $user = [xml]$userXml
                Write-Host "处理用户：$($user.用户.姓名)"
            }
        }
    }
    $reader.Close()

这些技巧将帮助您更有效地处理 XML 数据。记住，在处理大型 XML 文件时，考虑使用流式处理方法来优化内存使用。同时，始终注意 XML 文档的有效性和安全性。

这些脚本将帮助您实现零信任安全架构的关键组件。记住，零信任是一种安全模型，而不仅仅是一组技术工具。在实施这些技术时，建议与组织的安全策略结合，并确保遵循”最小权限原则”和”默认拒绝”的理念。同时，完整的零信任架构还需要结合其他安全技术，如多因素认证和微分段。

PowerShell 技能连载 - 针对Windows服务器的4种强大的PowerShell安全技术

简介

在不断发展的网络安全领域中，加固您的Windows服务器不仅是最佳实践，而且是必要的。PowerShell凭借其多功能性和自动化能力，在确保服务器安全的神奇旅程中成为我们可靠的魔杖。让我们讨论一下4种PowerShell安全技术，这将有助于实现我们的目标。

PowerShell安全性: 使用PowerShell进行审计

使用POSH-Sysmon配置Sysmon

Sysmon: 沉默的哨兵

由微软开发的Sysmon是一个强大的工具，用于监视系统并添加细粒度事件以便即使在重启后也能被跟踪。

这就像拥有一把神奇的放大镜，可以揭示服务器上隐藏的活动。

为什么使用POSH-Sysmon?

POSH-Sysmon是一个简化配置Sysmon 的PowerShell脚本。

它让您可以轻松地使用PowerShell创建和管理 Sysinternals Sysmon v2.0 配置文件。

通过Sysmon，您可以跟踪与进程创建、网络连接、注册表更改等相关的事件。

示例: 检测凭证提取尝试

要追踪最关键的事件之一——恶意进程尝试从内存中提取凭据时，

请使用 ProcessAccess 过滤器来检测Local Security Authority Subsystem Service (LSASS) 中此类尝试：

1
Get-WinEvent -LogName 'Microsoft-Windows-Sysmon/Operational' | Where-Object {$_.EventID -eq 10 -and $_.Message -like '*LSASS*'}

强化您的电子邮件堡垒：客户端规则转发阻止控制

为什么这很重要？

攻击者经常利用Office 365，在Outlook中设置静默规则，将敏感电子邮件转发到他们的账户。

通过启用客户端规则转发阻止控制来加强您的电子邮件安全性。

PowerShell操作:

使用PowerShell启用转发阻止：

1
Set-OrganizationConfig -RulesQuota 0

使用DSC进行PowerShell安全配置

什么是PowerShell DSC?

期望状态配置（DSC）就像一种魔法咒语，确保您的服务器保持安全配置。

它允许您定义和强制执行Windows服务器的期望状态。

示例：根据CIS基准进行安全配置

使用PowerShell DSC根据CIS Microsoft Windows Server 2019或Azure Secure Center Baseline for Windows Server 2016等基准应用安全配置。

您的DSC代码成为了您的护身符：

Configuration SecureServer {
    Import-DscResource -ModuleName SecurityPolicyDsc
    Node 'localhost' {
        SecurityPolicy 'Audit - Audit account logon events' {
            PolicySetting = 'Success,Failure'
        }
        # 更多安全设置在此处...
    }
}

HardeningKitty：Windows配置的猫护卫

小猫在忙什么？

HardeningKitty，我们的猫友，会自动检查和评估Windows系统的硬化。

它还会检查像Microsoft Office和Microsoft Edge这样的单个应用程序。

PowerShell完美性：

运行HardeningKitty来评估您系统的安全姿态：

1
.\HardeningKitty.ps1 -AuditSystem

结论

通过使用PowerShell，我们施展了审计、保护和加固我们的Windows服务器。记住，安全是一个持续不断的追求 —— 让你的咒语锋利，让你的PowerShell脚本更加精湛！

最佳实践

  1. 实施日志收集
  2. 分析日志模式
  3. 管理日志归档
  4. 保持详细的日志记录
  5. 定期进行日志分析
  6. 实施归档策略
  7. 建立日志索引
  8. 保持系统文档更新

  4. 保持详细的部署记录
  5. 定期进行健康检查
  6. 实施监控策略
  7. 建立告警机制
  8. 保持系统文档更新

function Get-DeviceCompliance {
    [CmdletBinding()]
    param(
        [ValidateSet('Basic','Advanced')]
        [string]$CheckLevel = 'Basic'
    )

    $report = [PSCustomObject]@{
        TPMEnabled     = $false
        BitLockerStatus = 'NotEncrypted'
        FirewallActive = $false
        LastUpdateDays = 999
        Compliant      = $false
    }

    try {
        # TPM状态检查
        $tpm = Get-CimInstance -ClassName Win32_Tpm -Namespace root/cimv2/Security/MicrosoftTpm
        $report.TPMEnabled = $tpm.IsEnabled_InitialValue

        # BitLocker检查
        $blv = Get-BitLockerVolume -MountPoint $env:SystemDrive 2>$null
        $report.BitLockerStatus = if($blv.ProtectionStatus -eq 'On') {'Encrypted'} else {'NotEncrypted'}

        # 防火墙状态
        $fw = Get-NetFirewallProfile | Where-Object {$_.Enabled -eq 'True'}
        $report.FirewallActive = [bool]($fw | Measure-Object).Count

        # 系统更新检查
        $lastUpdate = (Get-HotFix | Sort-Object InstalledOn -Descending | Select-Object -First 1).InstalledOn
        $report.LastUpdateDays = (New-TimeSpan -Start $lastUpdate -End (Get-Date)).Days

        # 高级检查
        if($CheckLevel -eq 'Advanced') {
            $report | Add-Member -NotePropertyName SecureBoot -NotePropertyValue (Confirm-SecureBootUEFI)
            $report | Add-Member -NotePropertyName HyperVEnabled -NotePropertyValue (Get-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V).State
        }

        # 合规判定
        $report.Compliant = $report.TPMEnabled -and
                          ($report.BitLockerStatus -eq 'Encrypted') -and
                          $report.FirewallActive -and
                          ($report.LastUpdateDays -lt 30)
    }
    catch {
        Write-Warning "设备检查异常: $_"
    }

    return $report
}

实现原理：

  1. 通过WMI/CIM接口获取TPM芯片状态，验证硬件安全基础
  2. 检查BitLocker加密状态，确保数据存储安全
  3. 扫描防火墙配置，确认至少有一个激活的防护配置文件
  4. 计算系统最后更新天数，确保漏洞及时修补
  5. 高级模式增加UEFI安全启动和虚拟化安全检查

使用示例：

1
2
3
4
5
# 基本检查
Get-DeviceCompliance

# 高级检查
Get-DeviceCompliance -CheckLevel Advanced

最佳实践：

  1. 与Intune等MDM解决方案集成
  2. 定期通过任务计划执行检查
  3. 对不合规设备启动修复流程
  4. 记录检查结果到中央日志服务器

注意事项：
• 需要本地管理员权限执行
• 部分检查仅支持Windows 10/11企业版
• 建议配合组策略共同使用

PowerShell 技能连载 - 25个最佳的Powershell脚本仓库

我最喜欢的部分之一是创建略有不同的脚本，我在这方面也取得了成功，并创建了Powershell脚本存储库。今天我必须说，我已经记不清自己创建了多少个脚本。除了AD、DNS和DHCP之外，此存储库还包含许多其他必备的脚本。从GPO到DFS Powershell脚本以及许多其他相关的Powershell脚本，使我的工作团队体验达到第九云。

这些脚本显然是为自动化而创建的，并且将它们保留在手头上被认为是犯罪行为，因此展示在该类别中。虽然我们知道组策略在任何环境中设置规则时起着重要作用，并且DFS也很重要，那么为什么不通过查看下面推荐书籍来更深入地了解它们呢？

为您提供的有用PowerShell命令

获取所有组策略命令

1
Get-command -Module grouppolicy

获取 GPO 报告

1
Get-GPOReport -All -Domain xyz.com

重置 GPO

1
Restore-GPO -Name "GPOname" -Path \\Server1\Backups

备份 GPO

1
Backup-Gpo -All -Path \\Server1\GpoBackups

获取DFS复制组

1
Get-DfsReplicationGroup -GroupName RG02

获取DFS复制成员

1
Get-DfsrMember -GroupName "RG07" -ComputerName "SRV01"

重启多台计算机
