Which of the following will BEST prevent external security attacks? 

Answer options:

A. Static IP addressing
B. Network address translation
C. Background checks for temporary employees
D. Securing and analyzing system access logs

B

Network address translation is helpful by having internal addresses that are nonroutable. Background checks of temporary employees are more likely to prevent an attack launched from within the enterprise. Static IP addressing does little to prevent an attack. Writing all computer logs to removable media does not help in preventing an attack.
