You are a professional Computer Hacking forensic investigator. You have been called to collect evidences of buffer overflow and cookie snooping attacks. Which of the following logs will you review to accomplish the task? Each correct answer represents a complete solution. Choose all that apply.
Correct Answer: A,C,D
Evidences of buffer overflow and cookie snooping attacks can be traced from system logs, event logs, and program logs, depending on the type of overflow or cookie snooping attack executed and the error recovery method used by the hacker. Answer option B is incorrect. Web server logs are used to investigate cross-site scripting attacks.
Question 82
CORRECT TEXT Fill in the blank with the appropriate term. ______________is a powerful and low-interaction open source honeypot.
Correct Answer:
Honeyd Explanation: Honeyd is a powerful and low-interaction open source honeypot. It was released by Niels Provos in 2002. It was written in C and designed for Unix platforms. It introduced a variety of new concepts, including the ability to monitor millions of unused IPs, IP stack spoofing, etc. It can also simulate hundreds of operating systems and monitor all UDP and TCP-based ports.
Question 83
Which of the following protocols supports source-specific multicast (SSM)?
Correct Answer: D
Question 84
Adam, a malicious hacker, has just succeeded in stealing a secure cookie via a XSS attack. He is able to replay the cookie even while the session is valid on the server. Which of the following is the most likely reason of this cause?
Correct Answer: D
Single key encryption uses a single word or phrase as the key. The same key is used by the sender to encrypt and the receiver to decrypt. Sender and receiver initially need to have a secure way of passing the key from one to the other. With TLS or SSL this would not be possible. Symmetric encryption is a type of encryption that uses a single key to encrypt and decrypt data. Symmetric encryption algorithms are faster than public key encryption. Therefore, it is commonly used when a message sender needs to encrypt a large amount of data. Data Encryption Standard (DES) uses the symmetric encryption key algorithm to encrypt data.
Question 85
Which of the following is a standard-based protocol that provides the highest level of VPN security?
Correct Answer: D
Internet Protocol Security (IPSec) is a standard-based protocol that provides the highest level of VPN security. IPSec can encrypt virtually everything above the networking layer. It is used for VPN connections that use the L2TP protocol. It secures both data and password. IPSec cannot be used with Point-to-Point Tunneling Protocol (PPTP). Answer option B is incorrect. The Internet Protocol (IP) is a protocol used for communicating data across a packet-switched inter-network using the Internet Protocol Suite, also referred to as TCP/IP.IP is the primary protocol in the Internet Layer of the Internet Protocol Suite and has the task of delivering distinguished protocol datagrams (packets) from the source host to the destination host solely based on their addresses. For this purpose, the Internet Protocol defines addressing methods and structures for datagram encapsulation. The first major version of addressing structure, now referred to as Internet Protocol Version 4 (IPv4), is still the dominant protocol of the Internet, although the successor, Internet Protocol Version 6 (IPv6), is being deployed actively worldwide. Answer option C is incorrect. Point-to-Point Protocol (PPP) is a remote access protocol commonly used to connect to the Internet. It supports compression and encryption and can be used to connect to a variety of networks. It can connect to a network running on the IPX, TCP/IP, or NetBEUI protocol. It supports multi- protocol and dynamic IP assignments. It is the default protocol for the Microsoft Dial-Up adapter. Answer option A is incorrect. Layer 2 Tunneling Protocol (L2TP) is a more secure version of Point-to-Point Tunneling Protocol (PPTP). It provides tunneling, address assignment, and authentication. It allows the transfer of Point-to-Point Protocol (PPP) traffic between different networks. L2TP combines with IPSec to provide tunneling and security for Internet Protocol (IP), Internetwork Packet Exchange (IPX), and other protocol packets across IP networks.
