The copyright certification exam is a comprehensive exam that covers eight domains of information security. These domains include security and risk management, asset security, security engineering, communication and network security, identity and access management, security assessment and testing, security operations, and software development security. copyright exam consists of 250 multiple-choice questions and is designed to test the candidate's knowledge, skills, and abilities in each of these domains. Passing the copyright certification exam requires a score of at least 700 out of 1000 points and a minimum of five years of professional experience in the information security field.

How to earn PCSA credentials?

The candidate must earn 50 continuing education units (CEUs) for the PCSA credential. The CEUs may be earned through participation in the ISSA - ISC2 Security Forum of Interest Community of Interest (COI), attendance at an Information Systems Security Association (ISSA) certified training course, obtaining CEUs from any other Information Systems Security Association or Information Systems Audit and Control Association (ISACA) member, obtaining certification credits for passing the exam, or through participating in many other online sites.The Professional level requires passing two exams to achieve. The PCSA credential is defined as conforming to the requirements of NCEES, the American Society for Testing and Materials (ASTM), and the International Information Systems Security Certification Consortium (ISC). The test will not earn a copyright valid certification.

NEW QUESTION # 595
What kind of encryption is realized in the S/MIME-standard?

  • A. Asymmetric encryption scheme
  • B. Elliptic curve based encryption
  • C. Public key based, hybrid encryption scheme
  • D. Password based encryption scheme

Answer: C

Explanation:
S/MIME (for Secure MIME, or Secure Multipurpose Mail Extension) is a security process used for e-mail exchanges that makes it possible to guarantee the confidentiality and non-repudiation of electronic messages. S/MIME is based on the MIME standard, the goal of which is to let users attach files other than ASCII text files to electronic messages. The MIME standard therefore makes it possible to attach all types of files to e-mails. S/MIME was originally developed by the company RSA Data Security. Ratified in July 1999 by the IETF, S/MIME has become a standard, whose specifications are contained in RFCs 2630 to 2633.
How S/MIME works
The S/MIME standard is based on the principle of public-key encryption. S/MIME therefore makes
it possible to encrypt the content of messages but does not encrypt the communication.
The various sections of an electronic message, encoded according to the MIME standard, are
each encrypted using a session key.
The session key is inserted in each section's header, and is encrypted using the recipient's public
key. Only the recipient can open the message's body, using his private key, which guarantees the
confidentiality and integrity of the received message.
In addition, the message's signature is encrypted with the sender's private key. Anyone
intercepting the communication can read the content of the message's signature, but this ensures
the recipient of the sender's identity, since only the sender is capable of encrypting a message
(with his private key) that can be decrypted with his public key.

NEW QUESTION # 596
A network security engineer needs to ensure that a security solution analyzes traffic for protocol manipulation and various sorts of common attacks. In addition, all Uniform Resource Locator (URL) traffic must be inspected and users prevented from browsing inappropriate websites.
Which of the following solutions should be implemented to enable administrators the capability to analyze traffic, blacklist external sites, and log user traffic for later analysis?

  • A. Circuit-Level Proxy
  • B. Intrusion Detection System (IDS)
  • C. Application-Level Proxy
  • D. Host-based Firewall

Answer: C

Explanation:
Application proxies provide one of the most secure types of access you can have in a security gateway. An application proxy sits between the protected network and the network you want to be protected from. Every time an application makes a request, the application intercepts the request to the destination system.


NEW QUESTION # 597
In order to provide dual assurance in a digital signature system, the design MUST include which of the following?

  • A. The hash of the signed document must be present.
  • B. The public key must be unique for the signed document.
  • C. The encrypted private key must be provided in the signing certificate.
  • D. signature process must generate adequate authentication credentials.

Answer: D


NEW QUESTION # 598
Which of the following is an appropriate source for test data?

  • A. Production data that has been sanitized before loading into a test environment.
  • B. Test data that has no similarities to production datA.
  • C. Production data that is secured and maintained only in the production environment.
  • D. Test data that is mirrored and kept up-to-date with production datA.

Answer: A

Explanation:
The most appropriate source for test data is production data that has been sanitized before loading into a test environment. Sanitization is the process of removing or modifying sensitive or confidential information from the data, such as personal identifiers, financial records, or trade secrets. Sanitized data preserves the characteristics and structure of the original data, but reduces the risk of exposing or compromising the data in the test environment. Production data that is secured and maintained only in the production environment is not a suitable source for test data, as it may not be accessible or available for testing purposes. Test data that has no similarities to production data is not a realistic or reliable source for test data, as it may not reflect the actual scenarios or conditions that the system will encounter in the production environment. Test data that is mirrored and kept up-to-date with production data is not a secure or ethical source for test data, as it may violate the privacy or confidentiality of the data owners or subjects, and expose the data to unauthorized access or modification in the test environment.

NEW QUESTION # 599
What principle focuses on the uniqueness of separate objects that must be joined together to perform a task? It is sometimes referred to as "what each must bring" and joined together when getting access or decrypting a file. Each of which does not reveal the other?

  • A. Separation of duties
  • B. Need to know
  • C. Dual control
  • D. Split knowledge

Answer: D

Explanation:
Split knowledge involves encryption keys being separated into two components,
each of which does not reveal the other. Split knowledge is the other complementary access
control principle to dual control.
In cryptographic terms, one could say dual control and split knowledge are properly implemented if
no one person has access to or knowledge of the content of the complete cryptographic key being
protected by the two rocesses.
The sound implementation of dual control and split knowledge in a cryptographic environment
necessarily means that the quickest way to break the key would be through the best attack known
for the algorithm of that key. The principles of dual control and split knowledge primarily apply to
access to plaintext keys.
Access to cryptographic keys used for encrypting and decrypting data or access to keys that are
encrypted under a master key (which may or may not be maintained under dual control and split
knowledge) do not require dual control and split knowledge. Dual control and split knowledge can
be summed up as the determination of any part of a key being protected must require the collusion
between two or more persons with each supplying unique cryptographic materials that must be
joined together to access the protected key.
Any feasible method to violate the axiom means that the principles of dual control and split
knowledge are not being upheld.
Split knowledge is the unique "what each must bring" and joined together when implementing dual
control. To illustrate, a box containing petty cash is secured by one combination lock and one
keyed lock. One employee is given the combination to the combo lock and another employee has
possession of the correct key to the keyed lock.
In order to get the cash out of the box both employees must be present at the cash box at the
same time. One cannot open the box without the other. This is the aspect of dual control.
On the other hand, split knowledge is exemplified here by the different objects (the combination to
the combo lock and the correct physical key), both of which are unique and necessary, that each
brings to the meeting. Split knowledge focuses on the uniqueness of separate objects that must be
joined together.
Dual control has to do with forcing the collusion of at least two or more persons to combine their
split knowledge to gain access to an asset. Both split knowledge and dual control complement
each other and are necessary functions that implement the segregation of duties in high integrity
cryptographic environments.
The following are incorrect answers:
Dual control is a procedure that uses two or more entities (usually persons) operating in concert to
protect a system resource, such that no single entity acting alone can access that resource. Dual
control is implemented as a security procedure that requires two or more persons to come
together and collude to complete a process. In a cryptographic system the two (or more) persons
would each supply a unique key, that when taken together, performs a cryptographic process.
Split knowledge is the other complementary access control principle to dual control.
Separation of duties - The practice of dividing the steps in a system function among different
individuals, so as to keep a single individual from subverting the process.
The need-to-know principle requires a user having necessity for access to, knowledge of, or
possession of specific information required to perform official tasks or services.
