Q

Is it enough to analyse log files, or is an IDS necessary?

The more network data you have to analyse, the better. In this expert response, Peter Wood explains what tools can provide the information you need.

Is it enough to analyse log files or it is necessary (or beneficial) to have an IDS feed to SIM/SEM as well? Will correlated logs provide enough information to pinpoint a security issue or does signature-based IDS provide me with an additional view, which cannot be replaced with just logs?
In principle, the more data you have to analyse, the better. A good IDS can give you invaluable information about attack types and help put log entries into context. I recommend visiting the SANS website for some excellent insight into this topic, especially its Top 5 Essential Log Reports document.
