CyberRookie CSX Fundamentals - Section 4: Security of Networks, Systems, Applications and Data with Complete Elaborations 1 / 24 1. risk: Is defined as the possibility of loss of a digital asset re... sulting from a threat exploiting a vulnerability 2. cyberrisk assessment: Of these attributes of risk must be analyzed to determine an organization's particular risk. 3. risk assessment methodology inputs: Asset identification, threat assessment and vulnerability assessment 4. cyberrisk assessment: Process begins with an examination of the risk sources (threats and vulnerabilities) for their positive and negative consequences. 5. risk: Can be ranked according to likelihood and impact. 6. Information used to estimate impact and likelihood usually comes from: - Past experience or data and records, Reliable practices, international standards or guidelines, Market research and analysis, Experiments and prototypes, Economic, engineering or other models, Specialist and expert advice 7. cyberrisk assessment: Existing controls and other mitigation strategies are evaluated to determine the level and effectiveness of risk mitigation currently in place and identify deficiencies and gaps that require attention. 8. If risk is not properly analyzed: The implementation of security is left to guesswork. 9. risk analyses: Can be oriented toward one of the inputs, making the risk assessment asset-oriented, threat-oriented or vulnerability-oriented 10. Asset: Important assets are defined first, and then potential threats to those assets are analyzed. Vulnerabilities are identified that may be exploited to access the asset. 11. Threat: Potential threats are determined first, and then threat scenarios are developed. Based on the scenarios, vulnerabilities and assets of interest to the adversary are determined in relation to the threat. [Show More]
