6a: Network Security
How would you determine if an organization’s network capacity is adequate or inadequate? What impacts could be expected if a portion of an organization’s network capacity is inadequate?
Suppose an organization is only able to filter and selectively block either: a) network traffic coming into its intranet from the internet (incoming) or b) network traffic going out to the internet (outbound). With respect to each of the 3 information system security objectives (i.e. confidentiality, integrity, and availability), if you could only filter and selectively block one network traffic direction which one you would you concentrate on and why?
In the contexts of being attacked by or unwittingly becoming a resource for distributed denial of service (DDoS), which is a bigger threat to an organization’s network and computer resources and why: Spam phishing or Spear phishing?
