QUESTION 521

A copy of evidence or oral description of its contents; which is not as reliable as best evidence is what type of evidence?

 

A.

Direct evidence

B.

Circumstantial evidence

C.

Hearsay evidence

D.

Secondary evidence

 

Correct Answer: D

Explanation:

Secondary evidence is a copy of evidence or oral description of its contents; not as reliable as best evidence

 

Here are other types of evidence:

 

Best evidence — original or primary evidence rather than a copy of duplicate of the evidence

Direct evidence — proves or disproves a specific act through oral testimony based on information gathered through the witness’s five senses

Conclusive evidence — incontrovertible; overrides all other evidence

Opinions — two types: Expert — may offer an opinion based on personal expertise and facts, Non-expert — may testify only as to facts

Circumstantial evidence — inference of information from other, immediate, relevant facts

Corroborative evidence — supporting evidence used to help prove an idea or point; used as a supplementary tool to help prove a primary piece of evidence

Hearsay evidence (3rdparty) — oral or written evidence that is presented in court that is second hand and has no firsthand proof of accuracy or reliability

 

(i) Usually not admissible in court

(ii) Computer generated records and other business records are in hearsay category

(iii) Certain exceptions to hearsay rule:

 

(1) Made during the regular conduct of business and authenticated by witnesses familiar with their use

(2) Relied upon in the regular course of business

(3) Made by a person with knowledge of records

(4) Made by a person with information transmitted by a person with knowledge

(5) Made at or near the time of occurrence of the act being investigated (6) In the custody of the witness on a regular basis

QUESTION 522

The first step in the implementation of the contingency plan is to perform:

 

A.

A firmware backup

B.

A data backup

C.

An operating systems software backup

D.

An application software backup

 

Correct Answer: B

Explanation:

A data backup is the first step in contingency planning. Without data, there is nothing to process. “No backup, no recovery”.

Backup for hardware should be taken care of next.

Formal arrangements must be made for alternate processing capability in case the need should arise.

Operating systems and application software should be taken care of afterwards.

QUESTION 523

How often should tests and disaster recovery drills be performed?

 

A.

At least once a quarter

B.

At least once every 6 months

C.

At least once a year

D.

At least once every 2 years

 

Correct Answer: C

Explanation:

Tests and disaster recovery drills should be performed at least once a year. The company should have no confidence in an untested plan. Since systems and processes can change, frequent testing will aid in ensuring a plan will succeed.

QUESTION 524

Which of the following groups represents the leading source of computer crime losses?

 

A.

Hackers

B.

Industrial saboteurs

C.

Foreign intelligence officers

D.

Employees

 

Correct Answer: D

Explanation:

There are some conflicting figures as to which group is a bigger threat hackers or employees. Employees are still considered to the leading source of computer crime losses. Employees often have an easier time gaining access to systems or source code then ousiders or other means of creating computer crimes.

 

A word of caution is necessary: although the media has tended to portray the threat of cybercrime as existing almost exclusively from the outside, external to a company, reality paints a much different picture. Often the greatest risk of cybercrime comes from the inside, namely, criminal insiders. Information security professionals must be particularly sensitive to the phenomena of the criminal or dangerous insider, as these individuals usually operate under the radar, inside of the primarily outward/external facing security controls, thus significantly increasing the impact of their crimes while leaving few, if any, audit trails to follow and evidence for prosecution.

 

Some of the large scale crimes committed agains bank lately has shown that Internal Threats are the worst and they are more common that one would think. The definition of what a hacker is can vary greatly from one country to another but in some of the states in the USA a hacker is defined as Someone who is using resources in a way that is not authorized. A recent case in Ohio involved an internal employee who was spending most of his day on dating website looking for the love of his life. The employee was taken to court for hacking the company resources.

 

The following answers are incorrect:

 

hackers. Is incorrect because while hackers represent a very large problem and both the frequency of attacks and overall losses have grown hackers are considered to be a small segment of combined computer fraudsters.

 

industrial saboteurs. Is incorrect because industrial saboteurs tend to go after trade secrets. While the loss to the organization can be great, they still fall short when compared to the los
ses created by employees. Often it is an employee that was involved in industrial sabotage.

 

foreign intelligence officers. Is incorrect because the losses tend to be national secrets. You really can’t put t cost on this and the number of frequency and occurances of this is less than that of employee related losses.

QUESTION 525

Which of the following is NOT a transaction redundancy implementation?

 

A.

on-site mirroring

B.

Electronic Vaulting

C.

Remote Journaling

D.

Database Shadowing

 

Correct Answer: A

Explanation:

Three concepts are used to create a level of fault tolerance and redundancy in transaction processing.

 

They are Electronic vaulting, remote journaling and database shadowing provide redundancy at the transaction level.

 

Electronic vaulting is accomplished by backing up system data over a network. The backup location is usually at a separate geographical location known as the vault site. Vaulting can be used as a mirror or a backup mechanism using the standard incremental or differential backup cycle. Changes to the host system are sent to the vault server in real-time when the backup method is implemented as a mirror. If vaulting updates are recorded in real-time, then it will be necessary to perform regular backups at the off-site location to provide recovery services due to inadvertent or malicious alterations to user or system data.

 

Journaling or Remote Journaling is another technique used by database management systems to provide redundancy for their transactions. When a transaction is completed, the database management system duplicates the journal entry at a remote location. The journal provides sufficient detail for the transaction to be replayed on the remote system. This provides for database recovery in the event that the database becomes corrupted or unavailable.

 

There are also additional redundancy options available within application and database software platforms. For example, database shadowing may be used where a database management system updates records in multiple locations. This technique updates an entire copy of the database at a remote location.

QUESTION 526

This type of supporting evidence is used to help prove an idea or a point, however It cannot stand on its own, it is used as a supplementary tool to help prove a primary piece of evidence. What is the name of this type of evidence?

 

A.

Circumstantial evidence

B.

Corroborative evidence

C.

Opinion evidence

D.

Secondary evidence

 

Correct Answer: B

Explanation:

This type of supporting evidence is used to help
prove an idea or a point, however It cannot stand on its own, it is used as a supplementary tool to help prove a primary piece of evidence. Corrobative evidence takes many forms.

 

In a rape case for example, this could consist of torn clothing, soiled bed sheets, 911 emergency calls tapes, and

prompt complaint witnesses.

 

There are many types of evidence that exist. Below you have explanations of some of the most common types:

Physical Evidence

 

Physical evidence is any evidence introduced in a trial in the form of a physical object, intended to prove a fact in issue based on its demonstrable physical characteristics. Physical evidence can conceivably include all or part of any object.

 

In a murder trial for example (or a civil trial for assault), the physical evidence might include DNA left by the attacker on the victim’s body, the body itself, the weapon used, pieces of carpet spattered with blood, or casts of footprints or tire prints found at the scene of the crime.

Real Evidence

Real evidence is a type of physical evidence and consists of objects that were involved in a case or actually played a part in the incident or transaction in question.

 

Examples include the written contract, the defective part or defective product, the murder weapon, the gloves used by an alleged murderer. Trace evidence, such as fingerprints and firearm residue, is a species of real evidence. Real evidence is usually reported upon by an expert witness with appropriate qualifications to give an opinion. This normally means a forensic scientist or one qualified in forensic engineering.

 

Admission of real evidence requires authentication, a showing of relevance, and a showing that the object is in “the same or substantially the same condition” now as it was on the relevant date. An object of real evidence is authenticated through the senses of witnesses or by circumstantial evidence called chain of custody.

 

Documentary

Documentary evidence is any evidence introduced at a trial in the form of documents. Although this term is most widely understood to mean writings on paper (such as an invoice, a contract or a wi
ll), the term actually include any media by which information can be preserved. Photographs, tape recordings, films, and printed emails are all forms of documentary evidence.

 

Documentary versus physical evidence

A piece of evidence is not documentary evidence if it is presented for some purpose other than the examination of the contents of the document. For example, if a blood-spattered letter is introduced solely to show that the defendant stabbed the author of the letter from behind as it was being written, then the evidence is physical evidence, not documentary evidence. However, a film of the murder taking place would be documentary evidence (just as a written description of the event from an eyewitness). If the content of that same letter is then introduced to show the motive for the murder, then the evidence would be both physical and documentary.

 

Documentary Evidence Authentication

Documentary evidence is subject to specific forms of authentication, usually through the testimony of an eyewitness to the execution of the document, or to the testimony of a witness able to identify the handwriting of the purported author. Documentary evidence is also subject to the best evidence rule, which requires that the original document be produced unless there is a good reason not to do so.

 

The role of the expert witness

Where physical evidence is of a complexity that makes it difficult for the average person to understand its significance, an expert witness may be called to explain to the jury the proper interpretation of the evidence at hand.

 

Digital Evidence or Electronic Evidence

Digital evidence or electronic evidence is any probative information stored or transmitted in digital form that a party to a court case may use at trial.

 

The use of digital evidence has increased in the past few decades as courts have allowed the use of e-mails, digital photographs, ATM transaction logs, word processing documents, instant message histories, files saved from accounting programs, spreadsheets, internet browser histories, databases, the contents of computer memory, computer backups, computer printouts, Global Positioning System tracks, logs from a hotel’s electronic door locks, and digital video or audio files.

 

While many courts in the United States have applied the Federal Rules of Evidence to digital evidence in the same way as more traditional documents, courts have noted very important differences. As compared to the more traditional evidence, courts have noted that digital evidence tends to be more voluminous, more difficult to destroy, easily modified, easily duplicated, potentially more expressive, and more readily available. As such, some courts have sometimes treated digital evidence differently for purposes of authentication, hearsay, the best evidence rule, and privilege. In December 2006, strict new rules were enacted within the Federal Rules of Civil Procedure requiring the preservation and disclosure of electronically stored evidence.

 

Demonstrative Evidence

Demonstrative evidence is evidence in the form of a representation of an object. This is, as opposed to, real evidence, testimony, or other forms of evidence used at trial.

 

Examples of demonstrative evidence include photos, x-rays, videotapes, movies, sound recordings, diagrams, forensic animation, maps, drawings, graphs, animation, simulations, and models. It is useful for assisting a finder of fact (fact-finder) in establishing context among the facts presented in a case. To be admissible, a demonstrative exhibit must “fairly and accurately” represent the real object at the relevant time.

 

Chain of custody

Chain of custody refers to the chronological documentation, and/or paper trail, showing the seizure, custody, control, transfer, analysis, and disposition of evidence, physical or electronic. Because evidence can be used in court to convict persons of crimes, it must be handled in a scrupulously careful manner to avoid later allegations of tampering or misconduct which can compromise the case of the prosecution toward acquittal or to overturning a guilty verdict upon appeal.

 

The idea behind recoding the chain of custody is to establish that the alleged evidence is fact related to the alleged crime – rather than, for example, having been planted fraudulently to make someone appear guilty.

 

Establishing the chain of custody is especially important when the evidence consists of fungible goods. In practice, this most often applies to illegal drugs which have been seized by law enforcement personnel. In such cases, the defendant at times disclaims any knowledge of possession of the controlled substance in question.

 

Accordingly, the chain of custody documentation and testimony is presented by the prosecution to establish that the substance in evidence was in fact in the possession of the defendant.

 

An identifiable person must always have the physical custody of a piece of evidence. In practice, this means that a police officer or detective will take charge of a piece of evidence, document its collection, and hand it over to an evidence clerk for storage in a secure place. These transactions, and every succeeding transaction between the collection of the evidence and its appearance in court, should be completely documented chronologically in order to withstand legal challenges to the authenticity of the evidence. Documentation should include the conditions under which the evidence is gathered, the identity of all evidence handlers, duration of evidence custody, security conditions while handling or storing the evidence, and the manner in which evidence is transferred to subsequent custodians each time such a transfer occurs (along with the signatures of persons involved at each step).

 

Example:

An example of “Chain of Custody” would be the recovery of a bloody knife at a murder scene:

Officer Andrew collects the knife and places it into a container, then gives it to forensics technician Bill. Forensics technician Bill takes the knife to the lab and collects fingerprints and other evidence from the knife. Bill then gives the knife and all evidence gathered from the knife to evidence clerk Charlene. Charlene then stores the evidence until it is needed, documenting everyone who has accessed the original evidence (the knife, and original copies of the lifted fingerprints).

 

The Chain of Custody requires that from the moment the evidence is collected, every transfer of evidence from person to person be documented and that it be provable that nobody else could have accessed that evidence. It is best to keep the number of transfers as low as possible.

 

In the courtroom, if the defendant questions the Chain of Custody of the evidence it can be proven that the knife in the evidence room is the same knife found at the crime scene. However, if there are discrepancies and it cannot be proven who had the knife at a particular point in time, then the Chain of Custody is broken and the defendant can ask to have the resulting evidence declared inadmissible.

 

“Chain of custody” is also used in most chemical sampling situations to maintain the integrity of the sample by providing documentation of the control, transfer, and analysis of samples. Chain of custody is especially important in environmental work where sampling can identify the existence of contamination and can be used to identify the responsible party.

QUESTION 527

Which of the following item would best help an organization to gain a common understanding of functions that are critical to its survival?

 

A.

A risk assessment

B.

A business assessment

C.

A disaster recovery plan

D.

A business impact analysis

 

Correct Answer: D

Explanation:

A Business Impact Analysis (BIA) is an assessment of an organization’s business functions to develop an understanding of their criticality, recovery time objectives, and resources needed.

By going through a Business Impact Analysis, the organization will gain a common understanding of functions that are critical to its survival.

A risk assessment is an evaluation of the exposures present in an organization’s external and internal environments.

A Business Assessment generally include Business Analysis as a discipline and it has heavy overlap with requirements analysis sometimes also called requirements engineering, but focuses on identifying the changes to an organization that are required for it to achieve strategic goals. These changes include changes to strategies, structures, policies, processes, and information systems.

A disaster recovery plan is the comprehensive statement of consistent actions to be taken before, during and after a disruptive event that causes a significant loss of information systems resources.

QUESTION 528

When preparing a business continuity plan, who of the following is responsible for identifying and prioritizing time-critical systems?

 

A.

Executive management staff

B.

Senior business unit management

C.

BCP committee

D.

Functional business units

 

Correct Answer: B

Explanation:

Many elements of a BCP will address senior management, such as the statement of importance and priorities, the statement of organizational responsibility, and the statement of urgency and timing. Executive management staff initiates the project, gives final approval and gives ongoing support. The BCP committee directs the planning, implementation, and tests processes whereas functional business units participate in implementation and testing.

QUESTION 529

Which of the following is a large hardware/software backup system that uses the RAID technology?

 

A.

Tape Array.

B.

Scale Array.

C.

Crimson Array

D.

Table Array.

 

Correct Answer: A

Explanation:

A Tape Array is a large hardware/software backup system based on the RAID technology.

 

There is a misconception that RAID can only be used with Disks. All large storage vendor from HP, to EMC, to Compaq have Tape Array based on RAID technology they offer.

 

This is a VERY common type of storage at an affordable price as well.

 

So RAID is not exclusively for DISKS. Often time this is referred to as Tape Librairies or simply RAIT.

RAIT (redundant array of independent tapes) is similar to RAID, but uses tape drives instead of disk drives. Tape storage is the lowest-cost option for very large amounts of data, but is very slow compared to disk storage. As in RAID 1 striping, in RAIT, data are striped in parallel to multiple tape drives, with or without a redundant parity drive. This provides the high capacity at low cost typical of tape storage, with higher-than-usual tape data transfer rates and optional data integrity.

QUESTION 530

Which of the following is the best reason for the use of an automated risk analysis tool?

 

A.

Much of the data gathered during the review cannot be reused for subsequent analysis.

B.

Automated methodologies require minimal training and knowledge of risk analysis.

C.

Most software tools have user interfaces that are easy to use and does not require any training.

D.

Information gathering would be minimized and expedited due to the amount of information already built into the tool.

 

Correct Answer: D

Explanation:

The use of tools simplifies this process. Not only do they usually have a database of assests, threats, and vulnerabilities but they also speed up the entire process.

 

Using Automated tools for performing a risk assessment can reduce the time it takes to perform them and can simplify the process as well. The better types of these tools include a well-researched threat population and associated statistics. Using one of these tools virtually ensures that no relevant threat is overlooked, and associated risks are accepted as a consequence of the threat being overlooked.

 

In most situations, the assessor will turn to the use of a variety of automated tools to assist in the vulnerability assessment process. These tools contain extensive databases of specific known vulnerabilities as well as the ability to analyze system and network configuration information to predict where a particular system might be vulnerable to different types of attacks. There are many different types of tools currently available to address a wide variety of vulnerability assessment needs. Some tools will examine a system from the viewpoint of the network, seeking to determine if a system can be compromised by a remote attacker exploiting available services on a particular host system. These tools will test for open ports listening for connections, known vulnerabilities in common services, and known operating system exploits.

 

Michael Gregg says:

Automated tools are available that minimize the effort of the manual process. These programs enable users to rerun the analysis with different parameters to answer “what-ifs.” They perform calculations quickly and can be used to estimate future expected losses easier than performing the calculations manually.

 

Shon Harris in her latest book says:

The gathered data can be reused, greatly reducing the time required to perform subsequent analyses. The risk analysis team can also print reports and comprehensive graphs to present to management.

The following answers are incorrect:

 

Much of the data gathered during the review cannot be reused for subsequent analysis. Is incorrect because the data can be reused for later analysis.

 

Automated methodologies require minimal training and knowledge of risk analysis. Is incorrect because it is not the best answer. While a minimal amount of training and knowledge is needed, the analysis should still be performed by skilled professionals.

 

Most software tools have user interfaces that are easy to use and does not require any training. Is incorrect because it is not the best answer. While many of the user interfaces are easy to use it is better if the tool already has information built into it. There is always a training curve when any product is being used for the first time.
