NEW QUESTION # 137
A cybersecurity analyst routinely checks logs, querying for login attempts. While querying for unsuccessful login attempts during a five-day period, the analyst produces the following report:
Which of the following BEST describes what the analyst Just found?
- A. A bot is running a brute-force attack in an attempt to log in to the domain.
- B. Users 4 and 5 are using their credentials to transfer files to multiple servers.
- C. An unauthorized user is using login credentials in a script.
- D. Users 4 and 5 are using their credentials to run an unauthorized scheduled task targeting some servers In the cloud.
Answer: C
Explanation:
A script is a program that can automate tasks or perform actions on a computer system. A script can be used to attempt multiple login attempts with different credentials, either randomly or from a list of known or guessed usernames and passwords. This can be done to gain unauthorized access to a system or to test its security12.
Users 4 and 5 are not using their credentials to transfer files or run tasks, because the report shows that they have failed login attempts on multiple servers. If they were authorized users, they would not have failed login attempts. Also, transferring files or running tasks does not require multiple login attempts on different servers.
A bot is a software application that runs automated tasks over the Internet. A bot can also be used to perform brute-force attacks, which are repeated attempts to guess a password or other authentication information. However, a bot would not use login credentials in a script, but rather generate random or common passwords to try3.
NEW QUESTION # 138
After a remote command execution incident occurred on a web server, a security analyst found the following piece of code in an XML file:
Which of the following it the BEST solution to mitigate this type of attack?
- A. Property configure XML handlers so they do not process sent parameters coming from user inputs.
- B. Implement a better level of user input filters and content sanitization.
- C. Escape user inputs using character encoding conjoined with whitelisting
- D. Use parameterized Queries to avoid user inputs horn being processed by the server.
Answer: B
Explanation:
The piece of code in the XML file is an example of a command injection attack, which is a type of attack that exploits insufficient input validation or output encoding to execute arbitrary commands on a server or system2 The attacker can inject malicious commands into an XML element that is processed by an XML handler on the server, and cause the server to execute those commands. The best solution to mitigate this type of attack is to implement a better level of user input filters and content sanitization, which means checking and validating any user input before processing it, and removing or encoding any potentially harmful characters or commands.

Which of the following BEST describes HSM?
- A. A computing device that manages cryptography, decrypts traffic, and maintains library calls
- B. A computing device that manages digital keys, performs encryption/decryption functions, and maintains other cryptographic functions
- C. A computing device that manages algorithms, performs entropy functions, and maintains digital signatures
- D. A computing device that manages physical keys, encrypts devices, and creates strong cryptographic functions
Answer: B
Explanation:
HSM (Hardware Security Module) is a computing device that manages digital keys, performs encryption/decryption functions, and maintains other cryptographic functions2. HSM is a dedicated crypto processor that is specifically designed for the protection of the crypto key lifecycle. HSM can store cryptographic keys that are used for encryption, authentication, digital signatures, and other security functions. HSM can also generate random keys that are unique to each device and never leave the chip. HSM can protect these keys from unauthorized access or tampering by using hardware isolation and encryption3. HSM can also measure and verify the integrity of the operating system and firmware on a device by using a process called attestation. HSM does not manage cryptography (A), as cryptography is the science or art of creating and using secret codes. HSM does not manage physical keys, as physical keys are tangible objects that are used to lock or unlock something. HSM does not manage algorithms (D), as algorithms are sets of rules or instructions that are used to solve problems or perform tasks.

Which of the following configuration changes would be the MOST appropriate for Mergence gathering?
- A. Develop a malware signature.
- B. Update the whitelist.
- C. Sinkhole the domains
- D. Update the Blacklist
Answer: D
Explanation:
A blacklist is a list of domains, IP addresses, email addresses, or other identifiers that are known or suspected to be malicious or harmful. A blacklist can be used to block or filter unwanted or dangerous traffic from reaching a network or system2 Updating the blacklist can help prevent phishing campaigns by adding the domains or email addresses of the phishing sources to the list and preventing them from sending emails to the company's employees.

NEW QUESTION # 146
Which of the following lines from this output most likely indicates that attackers could quickly use brute force and determine the negotiated secret session key?
- A. TLS_RSA_WITH_DES_CBC_SHA 56
- B. TLS_DHE_RSA_WITH_AES_256_GCM_SHA256 DH (2048 bits)
- C. TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 DH (1024 bits)
- D. TLS_RSA_WITH_AES_256_CBC_SHA 256
Answer: C
Explanation:
The line from this output that most likely indicates that attackers could quickly use brute force and determine the negotiated secret session key is TLS_DHE_RSA_WITH_AES_128_CBC_SHA 128 DH (1024 bits). This line indicates that the cipher suite uses Diffie-Hellman ephemeral (DHE) key exchange with RSA authentication, AES 128-bit encryption with cipher block chaining (CBC) mode, and SHA-1 hashing. The DHE key exchange uses a 1024-bit Diffie-Hellman group, which is considered too weak for modern security standards and can be broken by attackers using sufficient computing power. The other lines indicate stronger cipher suites that use longer key lengths or more secure algorithms.

NEW QUESTION # 148
Which of the following attack techniques has the GREATEST likelihood of quick success against Modbus assets?
- A. Buffer overflow
- B. Certificate spoofing
- C. Remote code execution
- D. Unauthenticated commands
Answer: D
Explanation:
Modbus is a communication protocol that is widely used in industrial control systems (ICS). Modbus does not have any built-in security features, such as authentication or encryption, which makes it vulnerable to various attacks. One of the most common and effective attack techniques against Modbus assets is to send unauthenticated commands to manipulate or disrupt the operation of the devices. Remote code execution, buffer overflow, and certificate spoofing are other attack techniques, but they have less likelihood of quick success against Modbus assets.

A security analyst discovers suspicious host activity while performing monitoring activities. The analyst pulls a packet capture for the activity and sees the following:
Which of the following describes what has occurred?
- A. The host attempted to download an application from utoftor.com.
- B. The host attempted to make a secure connection to utoftor.com.
- C. The host downloaded an application from utoftor.com.
- D. The host rejected the connection from utoftor.com.
Answer: B
Explanation:
The packet capture shows that the host sent a Client Hello message to utoftor.com on port 443. This message is part of the TLS (Transport Layer Security) handshake protocol, which is used to establish a secure connection between a client and a server1. The Client Hello message contains information such as the supported TLS version, cipher suites, and extensions that the client can use for the secure connection. The server is expected to respond with a Server Hello message that selects the parameters for the secure connection. However, the packet capture does not show any response from the server, which means that the host only attempted to make a secure connection to utoftor.com, but did not succeed. The host did not download (B) or reject (D) any application from utoftor.com.
