| What are the 4 common Commercial Business Classifications? | - Confidential - Private - Sensitive - Public |
| When is data exempt from FOIA? | - When the data is classified confidential. |
| What is information life cycle? | Procedures in place for retention and destruction of data. |
| What are the 7 main categories of access controls? | - Compensative - Corrective - Detective - Deterrent - Directive - Preventative - Recovery |
| In reference to access controls, what is the compensative category? What are some examples? | - In place to substitute for primary access control to act as a way to mitigate risks. - Two signatures before release, two keys to open box |
| In reference to access controls, what is the corrective category? What are some examples? | - In place to reduce the effect of an attack. Fixes and restores the entity. - Installing fire extinguishers, new firewall rules, restoring to previous server image |
| In reference to access controls, what is the detective category? What are some examples? | - In place to detect an attack while it's occurring to alert personnel. - Examples are motion detectors, IDS, logs, and job rotation. - Useful during an event. |
| In reference to access controls, what is the deterrent category? What are some examples? | - In place to deter or discourage an attacker. - Examples are user ID and authentication, fences and NDA's. |
| In reference to access controls, what is the directive category? What are some examples? | - Specify acceptable practice within an org. - Examples are Acceptable Use Policy (AUP) |
| In reference to access controls, what is the preventive category? What are some examples? | - Prevent an attack from occurring. - Controls are locks, badges, encryption, IPS's, security awareness training. |
| In reference to access controls, what is the recovery category? What are some examples? | - Recovering a system after an attack. Primary goal is restoring resources. - Examples are disaster recovery plans, data backups and offsite facilities. |
| What are types of access controls? | - Administrative (management) - Logical (technical) - Physical |
| What is an administrative (management) control? | Implemented to administer the org assets and personnel. Includes security policy, procedure standards, baselines est. by management. - Soft controls. |
| What is a logical (technical) control? | Controlling software or hardware to restrict access. Examples are firewalls, IDS, IPS, encryption and auditing and monitoring. - Most technical controls fall into the preventive category. |
| What is a physical control? | Implemented to protect an org facilities and personnel. Should take priority over all else. |
| What is STRM? | Security Requirement Traceability Matrix |
| In reference to FIPS 199, what is an SC? | Security Category Expresses the three tenets with their values for an organizational entity |
| How do you calculate the SC? | SC(Information Type) ={(confidentiality, impact), (integrity, impact), (availability, impact)} |
| What is another name for the FIPS 199 nomenclature to calculate the SC? | Aggregate CIA score |
| The following are examples of what? - Reckless/untrained employee - Partner - Disgruntled Employee - Internal/government spy - Vendor - Thief | Internal Actors |
| The following are examples of what? - Anarchist - Competitor - Corrupt Government Official - Data miner - Government Cyber Warrior - Terrorist | External Actor |
| Internal/External actors are divided in to what sub-categories? | - Hostile - Non-hostile |
| What criteria is used to analyze threat actors? | - Skill Level - Resources - Limits - Visibility - Objective - Outcome |
| What tool is used in risk management to identify vulnerabilities and threats? | Risk assessment |
| What are the 4 main goals of risk assessment? | - ID assets and asset value - ID vulnerabilities and threats - Calculate threat probability and business impact - Balance threat impact with countermeasure cost. |
| What does SLE stand for? | Single Loss Expectancy |
| What is SLE? | The monetary impact of each threat occurrence. SLE = AV * EF AV = Asset Value EF = Exposure Value |
| What is EV? | Exposure Value The percent value or functionality of an asset that will be lost when a threat occurs. |
| What does ALE stand for? | Annualized Loss Expectancy |
| What is ALE? | The expected risk factor of an annual threat event. |
| What is ARO? | Annualized Rate of Occurence |
| How do you calculate the ALE? | ALE = SLE * ARO |
| What is ARO? | Annualized Rate of Occurrence The estimate of how often a given threat might occur annually. |
| What is payback? | Comparing ALE against the expected savings as a result of an investment. |
| What is NPV? | Net Present Value Considers that money spent today is worth more than savings realized tomorrow. |
| How do you calculate the NPV? | Divide yearly savings by the discount rate. NPV = 2500/(1.1) = 2272.73 Multiply the 1.1 to the power of years. |
| What are the 4 strategies for risk reduction? | - Avoid - Transfer - Mitigate - Accept |
| What are 6 steps of risk management IAW NIST SP 800-30? | - Identify the assets and their value - Identify threats - Identify vulnerabilities - Determine likelihood - Identify impact - Determine risk (likelihood + impact) |
| What is residual risk? | residual risk = total risk - countermeasures |
