Description
Many companies put log files and log management on the back burner. Even applications in average-sized networks produce large volumes of log files every day, but administrators hardly ever find the time to look over them to uncover irregularities or problems. The reasons for this are threefold:
- The large volume of log files makes it more difficult to produce a useful analysis
- Users lack the necessary specialist knowledge to recognise entries that point to anomalies
- The log files are spread across individual systems, making access more difficult
This is incredibly unfortunate since log files in well-maintained systems and applications, when interpreted correctly, often give you early warning of security and configuration problems. If you overlook or ignore these, frequently a situation will arise that means you have to invest an inordinate amount of time and money to get it under control. In the environment described above, log files are commonly seen as a problem that must be eliminated. When it comes to dealing with log files, activities are limited to deleting them periodically to avoid problems resulting from a lack of drive space. Needless to say, if an attack goes unnoticed this makes it too easy for important troubleshooting information and even proof or evidence to go missing.
