ISC copyright Security Professional (copyright) Sample Questions (Q848-Q853):

NEW QUESTION # 848

  • A. Unsupported libraries are often used.
  • B. Vulnerabilities are difficult to detect.
  • C. Applications with multiple contributors are difficult to evaluate.
  • D. New software development skills are hard to acquire.

NEW QUESTION # 849
The ability to send malicious code, generally in the form of a client side script, to a different end user is categorized as which type of vulnerability?

  • A. Cross-Site Scripting (XSS)
  • B. Cross-site request forgery (CSRF)
  • C. Command injection
  • D. Session hijacking

Answer: A


NEW QUESTION # 850
Password management falls into which control category?

  • A. Compensating
  • B. Preventive
  • C. Technical
  • D. Detective

Answer: B

Explanation:
Password management is an example of preventive control.
Proper passwords prevent unauthorized users from accessing a system.
There are literally hundreds of different access approaches, control methods, and technologies, both in the physical world and in the virtual electronic world. Each method addresses a different type of access control or a specific access need.
For example, access control solutions may incorporate identification and authentication mechanisms, filters, rules, rights, logging and monitoring, policy, and a plethora of other controls. However, despite the diversity of access control methods, all access control systems can be categorized into seven primary categories.
The seven main categories of access control are:
1 Directive: Controls designed to specify acceptable rules of behavior within an organization
2 Deterrent: Controls designed to discourage people from violating security directives
3 Preventive: Controls implemented to prevent a security incident or information breach
4 Compensating: Controls implemented to substitute for the loss of primary controls and mitigate risk down to an acceptable level
5 Detective: Controls designed to signal a warning when a security control has been breached
6 Corrective: Controls implemented to remedy circumstance, mitigate damage, or restore controls
7 Recovery: Controls implemented to restore conditions to normal after a security incident

NEW QUESTION # 851
Which of the following is not an encryption algorithm?

  • A. DEA
  • B. SHA-1
  • C. Twofish
  • D. Skipjack

Answer: B

Explanation:
The SHA-1 is a hashing algorithm producing a 160-bit hash result from any data. It does not perform encryption.
In cryptography, SHA-1 is a cryptographic hash function designed by the United States
National Security Agency and published by the United States NIST as a U.S. Federal
Information Processing Standard.
SHA stands for "secure hash algorithm". The four SHA algorithms are structured differently and are distinguished as SHA-0, SHA-1, SHA-2, and SHA-3. SHA-1 is very similar to SHA-
0, but corrects an error in the original SHA hash specification that led to significant weaknesses. The SHA-0 algorithm was not adopted by many applications. SHA-2 on the other hand significantly differs from the SHA-1 hash function.
SHA-1 is the most widely used of the existing SHA hash functions, and is employed in several widely used applications and protocols.
In 2005, cryptanalysts found attacks on SHA-1 suggesting that the algorithm might not be secure enough for ongoing use. NIST required many applications in federal agencies to move to SHA-2 after 2010 because of the weakness. Although no successful attacks have yet been reported on SHA-2, they are algorithmically similar to SHA-1.
In 2012, following a long-running competition, NIST selected an additional algorithm,
Keccak, for standardization as SHA-3
NOTE:
A Cryptographic Hash Function is not the same as an Encryption Algorithm even thou both are Algorithms. An algorithm is defined as a step-by-step procedure for calculations.
Hashing Algorithm do not encrypt the data. People sometimes will say they encrypted a password with SHA-1 but really they simply created a Message Digest of the password using SHA-1, putting the input through a series of steps to come out with the message digest or hash value.
A cryptographic hash function is a hash function; that is, an algorithm that takes an arbitrary block of data and returns a fixed-size bit string, the (cryptographic) hash value, such that any (accidental or intentional) change to the data will (with very high probability) change the hash value. The data to be encoded are often called the "message," and the hash value is sometimes called the message digest or simply digest.
Encryption Algorithms are reversible but Hashing Algorithms are not meant to be reversible if the input is large enough.
The following are incorrect answers:
The Skipjack algorithm is a Type II block cipher with a block size of 64 bits and a key size of 80 bits that was developed by NSA and formerly classified at the U.S. Department of
Defense "Secret" level.
Twofish is a freely available 128-bit block cipher designed by Counterpane Systems (Bruce
Schneier et al.).
DEA is a symmetric block cipher, defined as part of the U.S. Government's Data Encryption
Standard (DES). DEA uses a 64-bit key, of which 56 bits are independently chosen and 8 are parity bits, and maps a 64-bit block into another 64-bit block.

NEW QUESTION # 852
Transport Layer Security (TLS) provides which of the following capabilities for a remote access server?

  • A. Application layer negotiation
  • B. Transport layer handshake compression
  • C. Peer identity authentication
  • D. Digital certificate revocation

Answer: C

Explanation:
Transport Layer Security (TLS) provides peer identity authentication as one of its capabilities for a remote access server. TLS is a cryptographic protocol that provides secure communication over a network. It operates at the transport layer of the OSI model, between the application layer and the network layer. TLS uses asymmetric encryption to establish a secure session key between the client and the server, and then uses symmetric encryption to encrypt the data exchanged during the session. TLS also uses digital certificates to verify the identity of the client and the server, and to prevent impersonation or spoofing attacks. This process is known as peer identity authentication, and it ensures that the client and the server are communicating with the intended parties and not with an attacker. TLS also provides other capabilities for a remote access server, such as data integrity, confidentiality, and forward secrecy.
