To ensure the integrity of the message and prevent it from being altered in transit, hashing can be used. Hashing is a process where a hash function converts data into a fixed-size string of characters, which is typically a hash code. When the message is sent, the hash code is generated and sent along with it. Upon receipt, the receiver can run the same hash function on the received message to generate a new hash code. If this new hash code matches the one sent with the message, it confirms that the message has not been altered. This method does not encrypt the message content but ensures that any changes to the message in transit can be detected.

References: The explanation is based on the principles of message integrity and non-repudiation as outlined in the EC-Council’s Certified Network Defender (CND) program, which includes understanding of network security controls and protocols, as well as the application of security measures to protect data integrity12.

Stateful Multilayer Inspection firewalls monitor the state of active connections and determine which network packets to allow through the firewall. They are designed to inspect the TCP handshake, which is the initial connection setup process between two hosts in a network. By monitoring this handshake, the firewall can determine whether a requested session is legitimate. This technology allows the firewall to not only filter packets based on predefined rules but also to ensure that the packets are part of an established and approved connection.

References: The role of Stateful Multilayer Inspection in monitoring TCP handshakes is covered in the Certified Network Defender (CND) course materials, which detail the functionalities of different firewall technologies and their application in network security123.

 The attacker is employing a Dictionary attack, which is a method where a file containing a list of commonly used passwords is used to attempt to gain unauthorized access to user accounts. This technique relies on the probability that many users will use common passwords that are easy to guess. It is more efficient than a brute-force attack since it uses a predefined list of words, rather than trying all possible combinations of characters.

References: The Dictionary attack is defined as a word-based brute force method1, and it is specifically mentioned as a password cracking test that can be automated with tools2. This technique is distinct from the other options because:

• A Brute-force attack involves trying all possible combinations of characters until the correct one is found1.
• A Rainbow table attack uses precomputed tables of hash values to crack encrypted passwords1.
• A Hybrid attack combines elements of both brute-force and dictionary attacks, often by adding numbers or symbols to dictionary words2.

In the context of event log management, the wrapping method refers to a technique where event logs are arranged in the form of a circular buffer. This means that when the allocated space for the logs is filled, new events start to overwrite the oldest events. This method ensures that the most recent events are always available, but older events are eventually overwritten as new ones come in. It is particularly useful for systems that generate a large number of events and have limited storage capacity for logs.

References: The wrapping method is a standard approach in various logging systems and is often used in scenarios where maintaining the most recent logs is more critical than preserving all historical logs indefinitely12.
