从 Excel 中的数据为 PowerShell 添加防火墙规则

[英]Add firewall rules over PowerShell from data in Excel

我需要从 excel 文件的长列表中创建新的防火墙规则。 为此,我将使用 PowerShell 和 ImportExcel 模块。 考虑到我在 Windows 和 PowerShell 中是菜鸟,我需要帮助才能真正做到这一点。

excel 的第一列代表 IpAndPorts,我需要阻止并添加为防火墙规则。 我需要从“第 2 行”获取数据,直到 excel 数据结束。

以下是 excel 的示例:

Excel 行 IpAndPorts 协议
2 35.180.0.0/16 TCP
3 12.13.14.1/8883,433 TCP
4 1.2.3.4/80 HTTP

我还需要将 New-NetFirewallRule 命令中的 -DisplayName 和 -Name 设置为动态的,以便稍后找到防火墙规则(一些代码示例)。

PowerShell 中的命令我将用于创建防火墙规则:

New-NetFirewallRule -DisplayName "Block WiFi {Excel-Row} " -Name "Block Wifi {Excel-Row} " -Direction Inbound -InterfaceType Wireless -Action Block -RemoteAddress {Part before / IpAndPorts} -LocalPort {Part after / IpAndPorts} -协议{协议}

从 Excel 获取第 3 行数据后的命令示例:

New-NetFirewallRule -DisplayName "Block WiFi 3 " -Name "Block Wifi 3 " -Direction Inbound -InterfaceType Wireless -Action Block -RemoteAddress 12.13.14.1 -LocalPort 8883,433 -Protocol TCP

更新:这是我设法编写的代码:

# ---------------------------------------
# Here we should get data from excel
# and prepare variables

$FirewallList = Import-Excel C:\Temp\list.xlsx
$All = $FirewallList.IpAndPorts
$AllProtocols = $FirewallList.Protocol

# ---------------------------------------
# Here it should be number of excel row, 
# starting from 2 and incementing until last data in row
# Don't know how to do that

$Index = "1"

# ---------------------------------------
# Split IpAndPorts data to get IP and PORT

$Ip = $All.Split("/")[0]
$Port = $All.Split("/")[1]

# ---------------------------------------
# Here we should populate parameters

#$Params = @{ 
#    "DisplayName" = 'Block-WiFi-' + $Index  
#    "Name" = 'Block-WiFi-' + $Index 
#    "Direction" = 'Inbound' 
#    "InterfaceType" = 'Wireless'
#    "Action" = 'Block'
#    "RemoteAddress" = $Ip
#    "LocalPort" = $Port
#    "Protocol" = $AllProtocols
#}

# Here we should start the command
# New-NetFirewallRule @Params

# ---------------------------------------
# Test how the command will be assembled 
# based on data from excel

$Test = New-Object PSObject -Property @{
    DisplayName = "Block-WiFi-" + $Index  
    Name = "Block-WiFi-" + $Index 
    Direction = 'Inbound' 
    InterfaceType = 'Wireless'
    Action = 'Block'
    RemoteAddress = $Ip
    LocalPort = $Port
    Protocol = $AllProtocols
}

Write-Host "New-NetFirewallRule
-DisplayName $($Test.DisplayName)
-Name $($Test.Name)
-Direction $($Test.Direction) 
-InterfaceType $($Test.InterfaceType)
-Action $($Test.Action)
-RemoteAddress $($Test.RemoteAddress)
-LocalPort $($Test.LocalPort)
-Protocol $($Test.Protocol)
"
# Test results. Just printing
Write-Host "------------- PRINT FROM EXCEL ----------------"
$All
$AllProtocols
Write-Host "---------------------------------------------"
$Ip
$Port

如何使循环从 excel 中获取每个值,添加到 $Params 和午餐命令?

提前致谢..!!!

当您加载 Excel 文件时

$FirewallList = Import-Excel C:\Temp\list.xlsx
$All = $FirewallList.IpAndPorts
$AllProtocols = $FirewallList.Protocol

尝试做$FirewallList.Count - 这是行数。

然后,您可以通过更改$FirewallList[i] i的 i (从 0 开始)来访问每一行,与上面的其他变量相同。

对于您的示例:

$FirewallList.Count
3


$FirewallList[0]
IpAndPorts          Protocol
----------          --------
35.180.0.0/16       TCP     

您还可以通过所有元素使用 foreach 循环到 go。
