If you are serious about infosec certifications, check out GIAC (http://www.giac.org) . The certs are very applied and test practical knowledge (e.g. they are open book... no need to test how well you can memorize stuff). CISSP is good to get you started in the field.
"Random" attacks can be reported to DShield.org . They have a number of scripts to automatically submit firewall logs (including from Linux firewalls). See http://www.dshield.org/howto.html . Once set up, it just "runs" and DShield aggregates the data, uses it for research and reports worst offenders to ISPs and other contacts.
You know you've landed gear-up when it takes full power to taxi.
