3.3 Summary 114 Lotus Security Handbook assessment planning. Keep in mind that communication is perhaps the primary success factor when planning the assessment, conducting tests and log audits, and of course, sharing the findings. In this chapter, we discussed the areas of concern for implementing a secure infrastructure architecture that meets the requirements of an organization’s security policy. The two main infrastructure requirements that must be considered are: To provide data confidentiality assurance – Encrypt confidential and sensitive information where required. – Facilitate both physical and logical server and network separation wherever possible. – Reduce exposure to network sniffing. – Identify appropriate parties authorized to access and update content. – Provide protection to back-end application and Web servers using network proxy layers. – Protect organizational resources with monitoring utilizing intrusion detection systems (IDS) To provide data integrity assurance – Ensure data remains unaltered in transit. – Provide integrity access controls for filtering updates and administration. – Support business continuity through redundancy and fail-over. – Utilize secure tools for maintenance activity to required subsystems. – Require infrastructure components to have all security vulnerability updates applied in a timely manner. – Utilize operational procedures that include auditing and reporting. – Assess system implementation to ensure it fulfills the security requirements. In the next few chapters we describe the technologies, components, and methods utilized to meet these secure infrastructure requirements, and how they can be used to create multi-layered defenses.
Chapter 4. Security components and layers 4 Metagroup defines a security architecture as “an orderly and comprehensive arrangement of security components.” So, what exactly constitutes an orderly arrangement? While there is no single answer to this question, we present some guidelines and recommendations in this chapter. Our sample policies and guidelines are based on best practices within <strong>IBM</strong> and on our experience working with customers. This chapter focuses on the technical methods used to support the general infrastructure security requirements we described in the previous chapter. In the first part of this chapter, we describe the various types of infrastructure components and their security functions. (You may already be familiar with the security components, so for you this will be a high-level review.) Next we discuss infrastructure design from a component placement and data flow standpoint. We describe a secure architecture model for providing security by utilizing multiple network zones with data flow boundaries, policies, and controls. And last, we describe a comprehensive top-to-bottom sequence of technologies and methods to provide a high degree of security in a computing environment. © Copyright <strong>IBM</strong> Corp. 2004.
