    An Introduction to Performing a Network Risk Analysis

    Whether in the public or private sector, businesses rely on information systems to carry out their business functions. Information systems can range from simple office networks, financial and personnel systems to highly specialized systems, such as those found in the military. Information systems are vulnerable to threats that can have a negative impact on an organization s operations, assets and reputation. These threats, both known and unknown, take advantage of system vulnerabilities to compromise the confidentiality, integrity, or availability of the information being processed, stored, or transmitted by those systems. Threats can be calculated attacks, environmental interferences, and machine errors and can result in great harm to business continuity. It is a necessity that management, at all levels, understand their responsibilities and are held accountable for managing information security risk.

    A Network Risk Analysis (NRA) is one of the key components of an organizational risk management process. A NRA will identify, prioritize, and estimate risk to an information system that may disrupt operations, assets, processes, and business continuity.
    The purpose of a NRA is to identify:
    Threats to information systems
    Vulnerabilities internal and external to information systems
    Impact to business continuity that may occur given the potential for threats exploiting vulnerabilities
    The likelihood that harm will occur.

    The end result (or benefit) of performing a risk analysis is the understanding of the level of risk within the network. NRAs are used to evaluate information system security related risks associated with corporate governance and management activities, mission/business processes or enterprise architecture, and funding of information security programs. NRAs are also used to support a corporate risk management framework (security categorization, security control selection, security control implementation, security control analysis, information system authorization, and monitoring).
