Case Study 2: Public Key Infrastructure

You are the Information Security Officer at a small software company. The
organization currently utilizes a Microsoft Server 2008 Active Directory domain
administered by a limited number of over-tasked network administrators. The
remainder of the organization comprises mostly software developers and a
relatively small number of administrative personnel. The organization has
decided that it would be in its best interest to use a public key infrastructure
(PKI) to provide a framework that fosters confidentiality, integrity,
authentication, and nonrepudiation. Email clients, virtual private network
products, Web server components, and domain controllers would utilize digital
certificates issued by the certificate authority (CA). Additionally, digital
certificates would be used to sign software developed by the company to
demonstrate software authenticity to the customer. 

Write a two to three
(2-3) page paper in which you:

2. Identify and analyze the fundamentals of PKI.
4. Analyze positive and negative characteristics of a Public and In-house
   CA.
6. Provide a sound recommendation for either a Public CA or an In-house
   CA.
