In addition, a host security solution, such as the Windows Firewall service, should be enabled. Follow the least privilege access principlesIn addition, enabling severely restricted tokens and access controls can reduce the potential for harm if an attacker is successful in compromising Windows system services. In general, following best practices for hardening hosts and networks can also help reduce the risk of attacks on Microsoft Windows system services.Important concepts related to services are shown below.MicrosoftWindows services are long-running executable applications that run within their own Windows session.Windows services must conform to the Service Control Manager interface rules and protocols.Services are ideal for running within a user's security context, can be used to launch user-specific applications, and can also run for long periods of time without interfering with other users using the same computer.Windows administrators can use the Services management unit, Sc.exe, or Windows PowerShell to manage services.8.8 Windows Event LoggingThe final topic discussed in this chapter is the Windows Event Log. By general definition, a log is a record made by the operating system of events that occur in the computer. The purpose of having the Windows operating system log is to record errors and events in a standard, centralized manner. This helps to track and resolve problems that occur with the computer. Windows event logs are the more common Windows logs that contain logs generated by the operating system and various applications (such as SQL Server and Internet Information Server [IIS]). Logs are constructed in a data format, so they can be easily searched and analyzed. A common tool for searching and analyzing logs is the Windows Event Viewer.
