function Get-B1DFPLog { <# .SYNOPSIS Queries the BloxOneDDI DFP Log .DESCRIPTION This function is used to query the BloxOneDDI DFP (DNS Forwarding Proxy) Logs. This is the log which contains all DNS Security related events. .PARAMETER Query Use this parameter to filter the DNS Logs by hostname or FQDN .PARAMETER Source Used to filter the DNS Log by IP Address .PARAMETER Type Used to filter the DNS Log by query type, such as "A" or "CNAME" .PARAMETER Response Use this parameter to filter the DNS Log by the response, i.e "NXDOMAIN" .PARAMETER DNSServers Filter the DNS Logs by one or more DNS Servers (i.e "mybloxoneddihost.mydomain.corp" or "mybloxoneddihost1.mydomain.corp","mybloxoneddihost2.mydomain.corp" .PARAMETER Start A date parameter used as the starting date/time of the log search. By default, the search will start from 24hrs ago and returns the latest results first. You may need to increase the -Limit parameter or reduce the -End date/time to view earlier events. .PARAMETER End A date parameter used as the end date/time of the log search. .PARAMETER Limit Use this parameter to limit the quantity of results. The default number of results is 100. .PARAMETER Offset Use this parameter to offset the results by the value entered for the purpose of pagination .Example Get-B1DFPLog -Source "10.10.132.10" -Query "google.com" -Type "A" -Response "216.58.201.110" -Start (Get-Date).AddHours(-6) -End (Get-Date) -Limit 1000 -Offset 0 .FUNCTIONALITY BloxOneDDI .FUNCTIONALITY Logs #> param( [string]$Query, [string]$Source, [string]$Type, [string]$Response, [datetime]$Start = (Get-Date).AddDays(-1), [datetime]$End = (Get-Date), [int]$Limit = 100, [int]$Offset = 0 ) $Start = $Start.ToUniversalTime() $End = $End.ToUniversalTime() $StartTime = $Start.ToString("yyyy-MM-ddTHH:mm:ss.000") $EndTime = $End.ToString("yyyy-MM-ddTHH:mm:ss.000") $splat = @{ "measures" = @() "dimensions" = @( "PortunusDnsLogs.timestamp" "PortunusDnsLogs.qname" "PortunusDnsLogs.device_name" "PortunusDnsLogs.qip" "PortunusDnsLogs.network" "PortunusDnsLogs.response" "PortunusDnsLogs.dns_view" "PortunusDnsLogs.query_type" "PortunusDnsLogs.mac_address" "PortunusDnsLogs.dhcp_fingerprint" "PortunusDnsLogs.user" "PortunusDnsLogs.os_version" "PortunusDnsLogs.response_region" "PortunusDnsLogs.response_country" "PortunusDnsLogs.device_region" "PortunusDnsLogs.device_country" ) "timeDimensions" = @( @{ "dimension" = "PortunusDnsLogs.timestamp" "dateRange" = @( $StartTime $EndTime ) } ) "filters" = @( @{ "member" = "PortunusDnsLogs.type" "operator" = "equals" "values" = @( "1" ) } ) "limit" = $Limit "offset" = $Offset "order" = @{ "PortunusDnsLogs.timestamp" = "desc" } "ungrouped" = $true } if ($Query) { $QuerySplat = @{ "member" = "PortunusDnsLogs.qname" "operator" = "contains" "values" = @( $Query ) } $splat.filters += $QuerySplat } if ($Type) { $QuerySplat = @{ "member" = "PortunusDnsLogs.query_type" "operator" = "equals" "values" = @( $Type ) } $splat.filters += $QuerySplat } if ($Response) { $ResponseSplat = @{ "member" = "PortunusDnsLogs.response" "operator" = "contains" "values" = @( $Response ) } $splat.filters += $ResponseSplat } if ($Source) { $SourceSplat = @{ "member" = "PortunusDnsLogs.qip" "operator" = "contains" "values" = @( $Source ) } $splat.filters += $SourceSplat } $Data = $splat | ConvertTo-Json -Depth 4 -Compress $Query = [System.Web.HTTPUtility]::UrlEncode($Data) $Result = Query-CSP -Method "GET" -Uri "$(Get-B1CSPUrl)/api/cubejs/v1/query?query=$Query" if ($Result.result.data) { $Result.result.data | Select-Object @{name="timestamp";Expression={$_.'PortunusDnsLogs.timestamp'}},` @{name="query";Expression={$_.'PortunusDnsLogs.qname'}},` @{name="device_name";Expression={$_.'PortunusDnsLogs.device_name'}},` @{name="device_ip";Expression={$_.'PortunusDnsLogs.qip'}},` @{name="network";Expression={$_.'PortunusDnsLogs.network'}},` @{name="response";Expression={$_.'PortunusDnsLogs.response'}},` @{name="dns_view";Expression={$_.'PortunusDnsLogs.dns_view'}},` @{name="query_type";Expression={$_.'PortunusDnsLogs.query_type'}},` @{name="mac_address";Expression={$_.'PortunusDnsLogs.mac_address'}},` @{name="dhcp_fingerprint";Expression={$_.'PortunusDnsLogs.dhcp_fingerprint'}},` @{name="user";Expression={$_.'PortunusDnsLogs.user'}},` @{name="os_version";Expression={$_.'PortunusDnsLogs.os_version'}},` @{name="response_region";Expression={$_.'PortunusDnsLogs.response_region'}},` @{name="response_country";Expression={$_.'PortunusDnsLogs.response_country'}},` @{name="device_region";Expression={$_.'PortunusDnsLogs.device_region'}},` @{name="device_country";Expression={$_.'PortunusDnsLogs.device_country'}} } else { Write-Host "Error: No DNS logs returned." -ForegroundColor Red } } |
