Jake, a network security specialist, is trying to prevent network-level session hijacking attacks in his company.While studying different types of such attacks, he learns about a technique where an attacker inserts their machine into the communication between a client and a server, making it seem like the packets are flowing through the original path. This technique is primarily used to reroute the packets. Which of the following types of network-level session hijacking attacks is Jake studying?

Man-in-the-middle Attack Using Forged ICMP and ARP Spoofing

A well-resourced attacker intends to launch a highly disruptive DDoS attack against a major online retailer. The attacker aims to exhaust all the network resources while keeping their identity concealed. Their method should be resistant to simple defensive measures such as IP-based blocking. Based on these objectives, which of the following attack strategies would be most effective?

The attacker should instigate a protocol-based SYN flood attack, consuming connection state tables on the retailer's servers

The attacker should execute a simple ICMP flood attack from a single IP, exploiting the retailer's ICMP processing

The attacker should leverage a botnet to launch a Pulse Wave attack, sending high-volume traffic pulses at regular intervals

The attacker should initiate a volumetric flood attack using a single compromised machine to overwhelm the retailer's network bandwidth

Given the complexities of an organization's network infrastructure, a threat actor has exploited an unidentified vulnerability, leading to a major data breach. As a Certified Ethical Hacker (CEH), you are tasked with enhancing the organization's security stance. To ensure a comprehensive security defense, you recommend a certain security strategy. Which of the following best represents the strategy you would likely suggest and why?

Adopt a Continual/Adaptive Security Strategy involving ongoing prediction, prevention, detection, and response actions to ensure comprehensive computer network defense.

Develop an in-depth Risk Management process, involving identification, assessment, treatment, tracking, and review of risks to control the potential effects on the organization.

Establish a Defense-in-Depth strategy, incorporating multiple layers of security measures to increase the complexity and decrease the likelihood of a successful attack.

Adopt a Continual/Adaptive Security Strategy involving ongoing prediction, prevention, detection, and response actions to ensure comprehensive computer network defense.

Implement an Information Assurance (IA) policy focusing on ensuring the integrity, availability, confidentiality, and authenticity of information systems.

An ethical hacker is hired to evaluate the defenses of an organization's database system which is known to employ a signature-based IDS. The hacker knows that some SQL Injection evasion techniques may allow him to bypass the system's signatures. During the operation, he successfully retrieved a list of usernames from the database without triggering an alarm by employing an advanced evasion technique. Which of the following could he have used?

Manipulating white spaces in SQL queries to bypass signature detection

Utilizing the char encoding function to convert hexadecimal and decimal values into characters that pass-through SQL engine parsing

Using the URL encoding method to replace characters with their ASCII codes in hexadecimal form

Implementing sophisticated matches such as "OR 'john' = john' in place of classical matches like 'OR 1-1'

Manipulating white spaces in SQL queries to bypass signature detection

During a recent vulnerability assessment of a major corporation's IT systems, the security team identified several potential risks. They want to use a vulnerability scoring system to quantify and prioritize these vulnerabilities. They decide to use the Common Vulnerability Scoring System (CVSS). Given the characteristics of the identified vulnerabilities, which of the following statements is the most accurate regarding the metric types used by CVSS to measure these vulnerabilities?

Base metric represents the inherent qualities of a vulnerability

Temporal metric represents the inherent qualities of a vulnerability

Base metric represents the inherent qualities of a vulnerability

Environmental metric involves the features that change during the lifetime of the vulnerability

Temporal metric involves measuring vulnerabilities based on a_ specific environment or implementation

An ethical hacker is testing the security of a website's database system against SQL Injection attacks. They discover that the IDS has a strong signature detection mechanism to detect typical SQL injection patterns.Which evasion technique can be most effectively used to bypass the IDS signature detection while performing a SQL Injection attack?

Leverage string concatenation to break identifiable keywords

Implement case variation by altering the case of SQL statements

Employ IP fragmentation to obscure the attack payload

Use Hex encoding to represent the SQL query string

Leverage string concatenation to break identifiable keywords

As a cybersecurity professional, you are responsible for securing a high-traffic web application that uses MySQL as its backend database. Recently, there has been a surge of unauthorized login attempts, and you suspect that a seasoned black-hat hacker is behind them. This hacker has shown proficiency in SQL Injection and appears to be using the 'UNION' SQL keyword to trick the login process into returning additional data.However, your application's security measures include filtering special characters in user inputs, a method usually effective against such attacks. In this challenging environment, if the hacker still intends to exploit this SQL Injection vulnerability, which strategy is he most likely to employ?

The hacker attempts to bypass the special character filter by encoding his malicious input, which could potentially enable him to successfully inject damaging SQL queries

The hacker alters his approach and injects a 'DROP TABLE' statement, a move that could potentially lead to the loss of vital data stored in the application's database

The hacker tries to manipulate the 'UNION' keyword in such a way that it triggers a database error, potentially revealing valuable information about the database's structure

The hacker switches tactics and resorts to a 'time-based blind' SQL Injection attack, which would force the application to delay its response, thereby revealing information based on the duration of the delay

The hacker attempts to bypass the special character filter by encoding his malicious input, which could potentially enable him to successfully inject damaging SQL queries
