improving signal to noise ratio from centralized network syslogs
Splunk is the obvious solution that most organizations with a mature
security group will likely already have in their portfolio.
Going a step further, and with an abundance of skill, ability, and
forethought: either ELK (or any derivative there of such as: Elasticache,
Fluentd, Kibana), or rsyslog|syslog-ng + database + loganalzyer.
Grep-fu will pay dividends in any of the three options (do nothing, go
proprietary, go open).
