Perhaps the biggest factor for Security Information in order to Event Management projects today simply is integrating application level data and events so long as detailed user-centric auditing, detect internal fraud and meet the needs of new regulations. The ability to smell aromas of user behavior and application level events is not really available with most it not exclusively SIEM products and cuts down on the overall value they produced whenever their potential. In fundament terms, Security Information and Event Management applications live through doorways and windows not at the treasure insides, your business applications.
Since basic application records of activity have insufficient data and they are generally I/O heavy, a non-intrusive approach really should detect, transform and route all relevant events to that SIEM applications in specific required format. Providing non-intrusive job detection while offloading individuality, formatting and routing as opposed to the business application server is extremely important. Enabling behavioral pattern analyse using pre-defined patterns, existing SIEM logic and external data correlation to use as real-time detection and reaction certainly is the next big step to attenuate internal fraud.
The SIEM market is evolving rapidly proving its value due to complex organizational world built on loads of IT components of different kinds. The need to manage a good number of data created by these components, document the data, archive it and detect problems and issues arising from the actual events made SIEM applications necessary. With that being said, for various reasons such as vendor industry and integration issues, the main objective of information gathering in order to correlation of events has always been on the technical parts of the IT network: Routers, Switches, Firewalls, Servers, the like. There has been no emphasis on the the actual business applications where similar actions, business processes and probable damage and fraudulent activity there can be be performed.
The current situation with most SIEM deployemtns should indeed be very problematic; all the peripherals include your audited and guarded although real honey pot, the "vault" with money in it, isn't paid for. It is in the merchant applications that the actual actions becoming performed, good or debilitating, and that is if your emphasis should be. Since organizations cannot tap into their application code and change it out to log and system relevant events, and repeat and again when legislation or business requirements barrier, a non-intrusive approach is extremely important as long as it is really provide in-depth, user-session capability visibility to user-application workout sessions. This means application communication needs no changes, write down management is unnecessary, and application servers just weren't over-loaded by logging I/O operations which cause performance downgrade.
Additional challenges would set you back transforming the data without it being fed to the SIEM application to correct mapping issues and parameter definitions which must be determined to help the SIEM application investigate data it is getting. Another main issue is allow you to deal with large throughputs to use as monitoring events from there are many applications per node, off-loading computation and I/O their own and routing and choosing events to relevant targets for example a SIEM application.
Only then will SIEM deployments fulfill detect every event or specific behaviors as mentioned in predefined patterns and outright then will SIEM software programs fulfill their true eventual. SIEM application can then gather critical, application numbers data and events, meet the needs of tougher regulations and correspondence internal frauds by correlating this data with it existing scientific tests.
