Host, server, client, terminal and domain controller are all synonyms in this context UDP: a) bits b) logical addressing c) data reformatting d) simplex - ✔✔-UDP is a simplex protocol at the Transport layer UDP provides application multiplexing (via port numbers) and integrity verification (via checksum) of the header and payload. Abnormal or unauthorized activities detectable by IDS (select all that apply) a) External connection attempts b) Execution of malicious code c) Access to controlled object d) none of the above - ✔✔-a, b and c The question does not specify NIDS (network IDS) nor HIDS (Host ISD). Therefore assume both types. WiFi technique using a form of serial communication: a) Spread Spectrum b) FHSS c) DSSS d) OFDM - ✔✔-b) FHSS (Frequency Hopping Spread Spectrum) is an early implementation of frequency spread spectrum. Instead of sending data in a parallel fashion, it transmits data in a series while constantly changing the frequency in use. Direct Sequence Spread Spectrum (DSSS) employs all the available frequencies simultaneously in parallel Orthogonal frequency-division multiplexing (OFDM) sends data in multiple streams at the same time Cryptography: What term defines when the same text encrypted by different keys produces the same cyphertext?

It overrides controls and gives full access and control of the object Which of the following is the most distinctive concept in relation to layered security? a) Multiple b) Series c) Parallel d) Filter - ✔✔-b) Series. Layered security implies multiple layers and security controls in a series faction: one control after the other and if one control fails the overall security is not compromised What is the primary objective of data classification schemes? a) To control access to objects by authorized subjects b) To formalize and stratify the process of securing data based on assigning labels of importance and sensitivity c) To establish an transaction trail for auditing accountability d) To manipulate access control to provide for the most efficient mean to grant or restrict functionality - ✔✔-b) To formalize and stratify the process of securing data on assigning labels of importance and sensitivity. note that a) mainly refers to access control Military labels of data classification - ✔✔-Top Secret Secret Confidential Sensitive but unclassified Unclassified Note that Top Secret, Secret and Confidential are known as "Classified Information" in Military or Governmental organizations Commercial/Business Organization:s labels of data classification - ✔✔-Confidential (or Private for PII) Sensitive (or Internal) Public Breaches vs. Threat events - ✔✔-A breach is the occurrence of a security mechanism being bypassed or thwarted by a threat agent. Threat events are accidental and intentional exploitations of vulnerabilities. They can also be natural or manmade. Threat events include fire, earthquake, flood, system failure, human error (due to a lack of training or ignorance), and power outage. When a safeguard or countermeasure is non existent or inefficient, what remains? a) Vulnerability b) Risk c) Exposure d) Penetration - ✔✔-a) Vulnerability Vulnerability is the absence or weakness of a safeguard or countermeasure Risk is the possibility or likelihood that a threat will exploit a vulnerability to cause harm to an asset. It is an assessment of probability, possibility, or chance. Exposure is being susceptible to asset loss because of a threat; Vulnerability vs. Exposure - ✔✔-Vulnerability is the absence or weakness of a safeguard or countermeasure. Exposure is being susceptible to asset loss because of a threat; there is the possibility that a vulnerability can or will be exploited by a threat agent or event. What security control is directly focused on preventing collusion? a) Principle of least privilege b) Job rotation c) Separation of duties d) Qualitative risk analysis - ✔✔-c) Job rotation Separation of duties and Least privilege do not PREVENT collusion. In fact by giving people less privileges and by separating and limiting their duties people are required to collude if they want to commit any wrongdoing. That does not mean they should not be implemented, but collusion is usually taking place within environment where there is proper separation of duties and minimum privileges being used. Else there would be no need to collude if people have too much permission and have privileges to all of the data or system. Separation of duties prevents fraud. The principle of least privilege prevents unauthorized access to protected or sensitive objects and information. Notice that the likelihood that a co-worker will be willing to collaborate in a illegal or abusive activity is reduced because of the higher risk of detection created by the combination of separation of duties, reduced job responsibilities and job rotation You've performed a risk analysis and implemented a countermeasure. When evaluating the risk after the implementation, which of the following would be reduced? a) Exposure factor (EF) b) Single loss expectancy (SLE) c) Asset value d) Annualized Rate of Occurrence (ARO) - ✔✔-d) Annualized Rate of Occurrence The EF is the % of the asset's value that is lost if the vulnerability is exploited. If the vulnerability is exploited after the implementation of the countermeasure the loss would be the same (think if the countermeasure would not work). Therefore the EF would be the same and its SLE. A safeguard changes the ARO. In fact, the whole point of a safeguard is to reduce the ARO. In other words, a safeguard should reduce the number of times an attack is successful in causing damage to an asset. What unit of measurement should be used to assign quantitative values to assets in the priority identification phase of the Business Impact Assessment? a) Monetary b) Utility c) Importance d) Time - ✔✔-a) Monetary "Importance" is a qualitative metric *BCP Overview* 4 main steps: *1) Project scope and planning* *2) Business impact assessment* *3) Continuity planning * *4) Approval and implementation* *1) Project Scope and Planning:* a) Structured analysis of the BIZ's organization from a crisis planning point of view b) The creation of a BCP team with the approval of senior management c) An assessment of the resources available to participate in BC activities d) An Analysis of legal & regulatory landscape that governs an organization's response to a catastrophic event *2) Business impact assessment* a) Identify (Business) Priorities b) Risk Identification c) Likelihood Assessment d) Impact Assessment e) Resources Prioritization *3) Continuity planning * a) Strategy development b) Provisions and processes *4) Plan approval and Implementation* a) Plan Approval b) Plan implementation c) Training and education d) BCP documentation - ✔✔- Which tasks of the BCP bridges the gap between the Business Impact Assessment and the Continuity Planning phases? a) Resources Prioritization b) Likelihood Assessment c) Strategy Development d) Procedures and Processes - ✔✔-c) Strategy Development bridges the gap by analyzing the prioritized list of risks identified during the BIA and determined which risks will be addressed by the BCP Planning phase Which criminal law was the first to implemented penalties for the creators of viruses, worms, Trojan Horses, and other types of malicious code that cause harm to computer system(s)? a) Computer Security Act b) National Insurance Protection Act c) Computer Fraud and Abuse Act d) Electronic Communications Privacy Act - ✔✔-c) Computer Fraud and Abuse Act Which law first required operators of federal interest computer systems to undergo periodic training in computer security issues? a) Computer Security Act b) National Infrastructure Protection Act c) Computer Fraud and Abuse Act d) Electronic Communications Privacy Act - ✔✔-a) Computer Security Act What is the broadest category of computer systems protected by the Computer Fraud and Abuse Act, as amended? a) Government-owned systems b) Federal interest systems c) Systems used in interstate commerce e) Systems located in the USA - ✔✔-c) Systems used in Interstate commerce Richard recently developed a great name for a new product that he plans to begin using immediately.
