Security
Information / Event Management (SIM/SEM/SIEM)
As networks grow and become more complex, so too
does the amount of data they produce. Everything, from switches to
databases produces event logs. Part of operating a secure infrastructure is
collecting, reviewing and managing the deluge of event data. Security
Information Management (SIM) or Security Event Management (SEM) (or sometimes
combined to SIEM) can provide automated methods to gather, normalize, store and
analyze event and log data.
SIM provides an enterprise-wide security monitoring and
administration solution that collects data on events, analyzes the data,
and provides a suitable response to threats on enterprise assets. It is
positioned as a security information management tool that can be used by
an enterprise-class network management centers or managed security
service providers with interest in protecting physical and/or logical
assets.
SIM Features
A good SIM deployment can offer many strong benefits.
- Event/log storage & archiving – A
good SIM will provide a common platform for gathering, normalizing,
and archiving logs and event data.
- Event aggregation and filtering – a
SIM can help you locate the key events in a deluge of noise.
- Searching & analysis – SIM products
automate searching and analyzing event data.
- Reporting – A SIM can help establish
metrics for analyzing IT and security performance.
- Proactive alerting – SIM can provide
real-time alerts regarding potentially dangerous activity.
- Incident response – A well managed
SIM can provide valuable information to security analysts in the
event of a security incident.
- Compliance – Many regulations
require log and event management of some type. A SIM installation
can help achieve compliance (it will not guarantee it.)
- Insight – Properly used, a SIM can
give network a security staff insight into operations and help
troubleshoot problems.
- Increased efficiency – A well
implemented SIM can help maximize staff resources required to
investigate and analyze security and network incidents.
Log Management vs. SIM
Log Management (LM) and SIM are very different technologies. LM
products are centralized repositories for logs generated throughout the
enterprise. LM will parse and normalize data for long-term storage.
Some LM products include basic reporting, searching and analysis tools.
SIM products offer the same basic
functionality as an LM product, but offer deeper analytical and alerting
capabilities, often correlating data across multiple data sources to
identify potential security events.
Log Management Features
Some of the common functions of a
log management system:
- Event/log storage & archiving – A
good LM will provide a common platform for gathering, normalizing,
and archiving logs and event data.
- Event aggregation and filtering –
Some LM products can perform some basic event filtering and
aggregation capabilities. .
- Reporting – Most LM products have
rudimentary reporting capabilities.
- Incident response – LM products can
be helpful when tracking down incidents, as all the event log data
is in one place.
- Searching & analysis – Most LM
products have some basic search and analytical tools.
