Answers to Assessment Test

  1. A. A vulnerability assessment is focused on uncovering vulnerabilities or weaknesses in an environment but by definition does not exploit those vulnerabilities.
  2. D. Mantraps are phonebooth-sized devices designed to prevent activities such as piggybacking and tailgating.
  3. A. Public-key infrastructure (PKI) is a system designed to control the distribution of keys and management of digital certificates.
  4. B. Wi-Fi Protected Access (WPA) is designed to protect wireless transmissions.
  5. A. White-box testing is done with full knowledge of the target environment. Black-box testing is done with very little or no information. Gray Box is performed with limited information somewhere between Black and White.
  6. B. Layer 2 Tunneling Protocol (L2TP) is a VPN technology used to establish secure connections over an insecure medium such as the Internet.
  7. A. Demilitarized zone (DMZ) structures act as a buffer zone between the Internet and an intranet, establishing a protected barrier. DMZs also allow for the placement of publicly accessible resources such as web servers in a semi-secure area.
  8. D. The escrow key is a key held by a third party used to perform cryptographic operations.
  9. D. Syn floods are a form of denial of service (DoS). Attacks of this type are designed to overwhelm a resource for a period of time.
  10. B. Sensors can be placed in different locations around a network with the intention of collecting information and returning it to a central location for analysis and viewing.
  11. A. Hardening is designed to remove nonessential services, applications, and other items from a system with the intent of making it fit a specific role as well as reducing its attack surface.
  12. A. Integrity ensures that information is kept reliable and accurate as well as allowing a party to examine the information to be able to detect a change.
  13. D. The Online Certificate Status Protocol (OCSP) is a protocol used to allow immediate verification of certificates’ validity as opposed to the older certificate revocation list (CRL) method, which allows for lags in detection.
  14. B. A switch allows for the creation of VLANs.
  15. A. The file itself is a Microsoft Word file and as such can have VBA macros embedded into it that can be used to deliver macro viruses.
  16. B. A network intrusion prevention system (NIPS) is similar to an intrusion detection system, but it adds the ability to react to attacks that it detects.
  17. C. A firewall between a web server and the Internet would enhance security and should always be present when exposing this asset to the Internet.
  18. D. A worm propagates by seeking out vulnerabilities it was designed to exploit and then replicating at an extreme rate.
  19. A. In a case like this, an individual showing up and asking to discuss intimate details of an environment may be attempting to obtain information for an attack.
  20. C. The FTP protocol is not designed to provide encryption, and as such, passwords and user IDs or names are not protected as they are with SSH, which uses encryption.
  21. A. A network intrusion detection system (NIDS) is installed at the network level and detects attacks at that level. Unlike a network-based intrusion prevention system (NIPS), an NIDS cannot stop an attack, but it can detect and report the attack to an administrator so that appropriate actions can be taken.
  22. B. Chain of custody is used in investigations and in the handling of evidence to ensure that no gaps in possession occur. Such gaps, if they occurred, could be used to invalidate a case.
  23. A. Steganography is used to conceal information inside of other information, thus making it difficult to detect.
  24. E. Acceptable use policy is an administrative tool used to inform the users of various company assets what is and isn’t considered appropriate use of assets.
  25. A. RSA is an example of an asymmetric encryption protocol that uses a public and private key. The others are examples of symmetric encryption protocols.
  26. C. SHA is an example of one type of hashing algorithm that is commonly used today. Another example would be MD5.
  27. A. MD5 is a hashing algorithm that creates a fixed-length output, as do all hashing algorithms. This fixed-length output is referred to as a hash or message digest.
  28. C. Biometrics is concerned with measuring physical traits and characteristics of a biological organism.
  29. A. Media access control (MAC) is a layer 2 construct in the OSI model. The physical address is coded into the network adapter itself and is designed to be unique.
  30. A. Computer forensics is the process of methodically collecting information relating to a security incident or crime.
  31. D. SSH is a modern protocol designed to be more secure and safer than protocols such as FTP and telnet. As such, the SSH protocol is replacing FTP and telnet in many environments.
  32. A. MD5 is a hashing algorithm that creates a fixed-length output, referred to as a hash or message digest. In the PKI world, SHA and MD5 are the most popular mechanisms for creating thumbprints for digital certificates
  33. B. Passwords are the simplest form of authentication and are commonly used. They fall under first-factor authentication and are referred to as something you know.
  34. A. An IP address is a logical address assigned at layer 3 and can be assigned to an IP-based system. The same IP address can be assigned to different systems, albeit at different times unlike MAC addresses.
  35. C. An IPv6 address has 128 bits as opposed to IPv4, which only has 32 bits. This increased amount of bits allows for the generation of many more IP addresses than is possible with IPv4.
