Investigating Service and Application Issues

Investigating application and service issues requires information about what services and applications are running and how they are expected to behave as well as self-reported and system-reported information about the services. In many organizations, active service monitoring will also be used to determine if the service is working properly.

Application- and service-related events like incorrect behavior, unexpected log messages or errors, new users or processes, and file changes are all common signs of a possibly compromised service. Fortunately, many of the tools you need to investigate these problems are already built into Windows and Linux systems.

Application and Service Monitoring

Monitoring applications and services is critical to an organization’s operations and can also provide important security insight by showing where unexpected behavior is occurring or where applications and services are being abused.
