若要给出包含代码示例的安全建议的KQL解决方案，可以参考以下示例：

1. 筛选访问未经授权的资源事件：

SecurityEvent 
| where EventID == 4663 
| where AccessMask == 0x100080 
| where AccountType == 'User' 
| project TimeGenerated, Account, ObjectName, AccessMask

2. 检测异常的账户登录活动：

SecurityEvent
| where EventID == 4625
| where FailureReason != 0
| project TimeGenerated, Account, FailureReason, FailureReasonText

3. 检测恶意软件传播行为：

DeviceFileEvents
| where InitiatingProcessFileName in~ ("explorer.exe", "winword.exe", "excel.exe")
| where ActionType in~ ("FileDownloaded", "FileCreated")
| where FolderPath contains "AppData"
| project TimeGenerated, InitiatingProcessFileName, FileName, FolderPath

4. 检测异常的网络通信：

NetworkCommunicationEvents
| where RemoteIPType == "Public"
| where RemoteIPCountry != "China"
| project TimeGenerated, LocalIP, RemoteIP, RemoteIPCountry, RemoteIPLatitude, RemoteIPLongitude

这些示例提供了一些常见的安全建议，可以根据具体的安全需求进行调整和扩展。
