Information security began with Rand Report R paper that started the study of computer security Scope of computer security grew from physical security to include: Safety of data Limiting unauthorized access to data Involvement of personnel from multiple levels of an organization.
The s Networks of computers became more common; so too did the need to interconnect networks Internet became first manifestation of a global network of networks Initially based on de facto standards In early Internet deployments, security was treated as a low priority.
What is Security?
The quality or state of being secureto be free from danger A successful organization should have multiple layers of security in place: Physical security Personal security Operations security Communications security Network security Information security The protection of information and its critical elements, including systems and hardware that use, store, and transmit that information Necessary tools: Key Information Security Concepts contd.
Critical Characteristics of Information The value of information comes from the characteristics it possesses: Balancing Information Security and Access Impossible to obtain perfect securityit is a process, not an absolute Security should be considered balance between protection and availability To achieve balance, level of security must allow reasonable access, yet protect against threats.
Approaches to Information Security Implementation: Bottom-Up Approach Grassroots effort: Participant support Organizational staying power.
Top-Down Approach Initiated by upper management Issue policy, procedures, and processes Dictate goals and expected outcomes of project Determine accountability for each required action. The most successful also involve formal development strategy referred to as systems development life cycle. Ensures a rigorous process Increases probability of success. Investigation What problem is the system being developed to solve? Objectives, constraints, and scope of project are specified Preliminary cost-benefit analysis is developed At the end, feasibility analysis is performed to assess economic, technical, and behavioral feasibilities of the process.
Analysis Consists of assessments of: The organization Current systems Capability to support proposed systems.
Analysts determine what new system is expected to do and how it will interact with existing systems Ends with documentation of findings and update of feasibility analysis. Logical Design Main factor is business need Applications capable of providing needed services are selected. Data support and structures capable of providing the needed inputs are identified Technologies to implement physical solution are determined Feasibility analysis performed at the end. Physical Design Technologies to support the alternatives identified and evaluated in the logical design are selected Components evaluated on make-or-buy decision Feasibility analysis performed Entire solution presented to end-user representatives for approval.
Implementation Needed software created Components ordered, received, and tested Users trained and documentation created Feasibility analysis prepared Users presented with system for performance review and acceptance test.
Maintenance and Change Longest and most expensive phase Consists of tasks necessary to support and modify system for remainder of its useful life Life cycle continues until the process begins again from the investigation phase When current system can no longer support the organizations mission, a new project is implemented.
The Security Systems Development Life Cycle The same phases used in traditional SDLC may be adapted to support specialized implementation of an IS project Identification of specific threats and creating controls to counter them SecSDLC is a coherent program rather than a series of random, seemingly unconnected actions.
Analysis Documents from investigation phase are studied Analysis of existing security policies or programs, along with documented current threats and associated controls Includes analysis of relevant legal issues that could impact design of the security solution Risk management task begins.
Logical Design Creates and develops blueprints for information security Incident response actions planned: Continuity planning Incident response Disaster recovery. Physical Design Needed security technology is evaluated, alternatives are generated, and final design is selected At end of phase, feasibility study determines readiness of organization for project.
Implementation Security solutions are acquired, tested, implemented, and tested again Personnel issues evaluated; specific training and education programs conducted Entire tested package is presented to management for final approval.
Maintenance and Change Perhaps the most important phase, given the everchanging threat environment Often, repairing damage and restoring information is a constant duel with an unseen adversary Information security profile of an organization requires constant adaptation as new threats emerge and old threats evolve. Security Professionals and the Organization Wide range of professionals required to support a diverse information security program Senior management is key component Additional administrative support and technical expertise are required to implement details of IS program.
