SSCP Exam Question 442
What can best be defined as the detailed examination and testing of the security features of an IT system or product to ensure that they work correctly and effectively and do not show any logical vulnerabilities, such as evaluation criteria?
Correct Answer: B
Section: Security Operation Adimnistration
Explanation/Reference:
Evaluation as a general term is described as the process of independently assessing a system against a standard of comparison, such as evaluation criteria. Evaluation criterias are defined as a benchmark, standard, or yardstick against which accomplishment, conformance, performance, and suitability of an individual, hardware, software, product, or plan, as well as of risk-reward ratio is measured.
What is computer security evaluation?
Computer security evaluation is the detailed examination and testing of the security features of an IT system or product to ensure that they work correctly and effectively and do not show any logical vulnerabilities. The Security Target determines the scope of the evaluation. It includes a claimed level of Assurance that determines how rigorous the evaluation is.
Criteria
Criteria are the "standards" against which security evaluation is carried out. They define several degrees of rigour for the testing and the levels of assurance that each confers. They also define the formal requirements needed for a product (or system) to meet each Assurance level.
TCSEC
The US Department of Defense published the first criteria in 1983 as the Trusted Computer Security Evaluation Criteria (TCSEC), more popularly known as the "Orange Book". The current issue is dated 1985. The US Federal Criteria were drafted in the early 1990s as a possible replacement but were never formally adopted.
ITSEC
During the 1980s, the United Kingdom, Germany, France and the Netherlands produced versions of their own national criteria. These were harmonised and published as the Information Technology Security Evaluation Criteria (ITSEC). The current issue, Version 1.2, was published by the European Commission in June 1991. In September 1993, it was followed by the IT Security Evaluation Manual (ITSEM) which specifies the methodology to be followed when carrying out ITSEC evaluations.
Common Criteria
The Common Criteria represents the outcome of international efforts to align and develop the existing European and North American criteria. The Common Criteria project harmonises ITSEC, CTCPEC (Canadian Criteria) and US Federal Criteria (FC) into the Common Criteria for Information Technology Security Evaluation (CC) for use in evaluating products and systems and for stating security requirements in a standardised way.
Increasingly it is replacing national and regional criteria with a worldwide set accepted by the International Standards Organisation (ISO15408).
The following answer were not applicable:
Certification is the process of performing a comprehensive analysis of the security features and safeguards of a system to establish the extent to which the security requirements are satisfied. Shon Harris states in her book that Certification is the comprehensive technical evaluation of the security components and their compliance for the purpose of accreditation.
Wikipedia describes it as: Certification is a comprehensive evaluation of the technical and non-technical security controls (safeguards) of an information system to support the accreditation process that establishes the extent to which a particular design and implementation meets a set of specified security requirements Accreditation is the official management decision to operate a system. Accreditation is the formal declaration by a senior agency official (Designated Accrediting Authority (DAA) or Principal Accrediting Authority (PAA)) that an information system is approved to operate at an acceptable level of risk, based on the implementation of an approved set of technical, managerial, and procedural security controls (safeguards).
Acceptance testing refers to user testing of a system before accepting delivery.

SSCP Exam Question 443
Which of the following does not address Database Management Systems (DBMS) Security?
Correct Answer: C
Padded cells complement Intrusion Detection Systems (IDSs) and are not related to DBMS security. Padded cells are simulated environments to which IDSs seamlessly transfer detected attackers and are designed to convince an attacker that the attack is going according to the plan. Cell suppression is a technique used against inference attacks by not revealing information in the case where a statistical query produces a very small result set. Perturbation also addresses inference attacks but involves making minor modifications to the results to a query. Partitioning involves splitting a database into two or more physical or logical parts; especially relevant for multilevel secure databases.

SSCP Exam Question 444
Of the protocols list, which one is connection oriented?
Correct Answer: D
SSCP Exam Question 445
Which one of the following is NOT one of the outcomes of a vulnerability assessment?
Correct Answer: C
Section: Risk, Response and Recovery
Explanation/Reference:
When seeking to determine the security position of an organization, the security professional will eventually turn to a vulnerability assessment to help identify specific areas of weakness that need to be addressed. A vulnerability assessment is the use of various tools and analysis methodologies to determine where a particular system or process may be susceptible to attack or misuse. Most vulnerability assessments concentrate on technical vulnerabilities in systems or applications, but the assessment process is equally as effective when examining physical or administrative business processes.
The vulnerability assessment is often part of a BIA. It is similar to a Risk Assessment in that there is a quantitative (financial) section and a qualitative (operational) section. It differs in that i t is smaller than a full risk assessment and is focused on providing information that is used solely for the business continuity plan or disaster recovery plan.
A function of a vulnerability assessment is to conduct a loss impact analysis. Because there will be two parts to the assessment, a financial assessment and an operational assessment, it will be necessary to define loss criteria both quantitatively and qualitatively.
Quantitative loss criteria may be defined as follows:
Incurring financial losses from loss of revenue, capital expenditure, or personal liability resolution The additional operational expenses incurred due to the disruptive event Incurring financial loss from resolution of violation of contract agreements Incurring financial loss from resolution of violation of regulatory or compliance requirements Qualitative loss criteria may consist of the following:
The loss of competitive advantage or market share
The loss of public confidence or credibility, or incurring public mbarrassment During the vulnerability assessment, critical support areas must be defined in order to assess the impact of a disruptive event. A critical support area is defined as a business unit or function that must be present to sustain continuity of the business processes, maintain life safety, or avoid public relations embarrassment.
Critical support areas could include the following:
Telecommunications, data communications, or information technology areas Physical infrastructure or plant facilities, transportation services Accounting, payroll, transaction processing, customer service, purchasing The granular elements of these critical support areas will also need to be identified. By granular elements we mean the personnel, resources, and services the critical support areas need to maintain business continuity Reference(s) used for this question:
