Slide 25

Establishing a CSIRT People (cont.) Forensic Expertise External (law authorization or private temporary worker) Still requires CSIRT for starting reaction May not be accessible for lesser offenses Mitigates issues of preparing and turnover. What to Look for Certified Computer Examiner Certified Cyber Crime Expert Certified Information Forensics Investigator Certified Computer Crime Investigator Certified Computer Forensic Examiner Certified Information Systems Auditor Investigative Experience Do they make a decent witness?

Slide 26

Establishing a CSIRT People (cont.) Forensic Expertise Internal Always accessible Talents can be coordinated at different undertakings when not required for legal sciences Develops recognition with your organization Training Same capabilities as outer specialists.

Slide 27

CSIRT Training Resources SANS Institute ( www.sans.org ) Intense School\'s CCE Applied Computer Forensics Boot Camp: www.intenseschool.com/bootcamps/default.asp Mares and Company, LLC\'s fundamental and propelled PC measurable preparing: www.dmares.com/maresware/training.htm NTI\'s scientific preparing: www.forensics-intl.com/training.html
