312-50v13 Exam Dumps - Certified Ethical Hacker Exam (CEHv13)

CEH v13 defines a white hat hacker as a security professional with explicit authorization to perform penetration testing, vulnerability assessments, and exploitation attempts within legal and contractual boundaries. Their objective is to strengthen security, not compromise it. White hats follow structured methodologies, document findings, and provide remediation recommendations. A black hat (Option A) acts maliciously and without permission. A grey hat (Option B) operates without authorization but without harmful intent, which is not compliant with corporate penetration testing procedures. Script kiddies (Option C) rely on pre-built tools without deep knowledge and are not employed for legitimate engagements. Therefore, the individual described is a white hat, operating under legal and ethical guidelines with organizational consent.

A hybrid attack combines a dictionary and brute-force approach. Given that:

Passwords are required to be complex

Users still often choose predictable variations (e.g., Password123!, Welcome@2024)

A hybrid attack is best suited because it applies common mutations to known words—much faster than full brute force and more effective than a plain dictionary attack.

From CEH v13 Courseware:

Module 6: Password Cracking → Attack Techniques

CEH v13 Study Guide states:

“Hybrid attacks combine the speed of dictionary attacks with some of the thoroughness of brute-force. It’s ideal when users use complex but predictable passwords.”

Incorrect Options:

A: Online attacks are slow and may trigger account lockouts.

B: Plain dictionary attacks won’t cover variations like “P@ssw0rd!”

C: Brute-force would be too slow for complex passwords.

The purpose of this idea is to permit multiple customers to figure on joint projects and applications that belong to the community, where it’s necessary to possess a centralized clouds infrastructure. In other words, Community Cloud may be a distributed infrastructure that solves the precise problems with business sectors by integrating the services provided by differing types of clouds solutions.

The communities involved in these projects, like tenders, business organizations, and research companies, specialise in similar issues in their cloud interactions. Their shared interests may include concepts and policies associated with security and compliance considerations, and therefore the goals of the project also .

Community Cloud computing facilitates its users to spot and analyze their business demands better. Community Clouds could also be hosted during a data center, owned by one among the tenants, or by a third-party cloud services provider and may be either on-site or off-site.

Community Cloud Examples and Use Cases

Cloud providers have developed Community Cloud offerings, and a few organizations are already seeing the advantages . the subsequent list shows a number of the most scenarios of the Community Cloud model that’s beneficial to the participating organizations.

Multiple governmental departments that perform transactions with each other can have their processing systems on shared infrastructure. This setup makes it cost-effective to the tenants, and may also reduce their data traffic.

Benefits of Community Clouds

Community Cloud provides benefits to organizations within the community, individually also as collectively. Organizations don’t need to worry about the safety concerns linked with Public Cloud due to the closed user group.

This recent cloud computing model has great potential for businesses seeking cost-effective cloud services to collaborate on joint projects, because it comes with multiple advantages.

Openness and Impartiality

Community Clouds are open systems, and that they remove the dependency organizations wear cloud service providers. Organizations are able to do many benefits while avoiding the disadvantages of both public and personal clouds.

Flexibility and Scalability

Ensures compatibility among each of its users, allowing them to switch properties consistent with their individual use cases. They also enable companies to interact with their remote employees and support the utilization of various devices, be it a smartphone or a tablet. This makes this sort of cloud solution more flexible to users’ demands.

Consists of a community of users and, as such, is scalable in several aspects like hardware resources, services, and manpower. It takes under consideration demand growth, and you simply need to increase the user-base.

High Availability and Reliability

Your cloud service must be ready to make sure the availability of knowledge and applications in the least times. Community Clouds secure your data within the same way as the other cloud service, by replicating data and applications in multiple secure locations to guard them from unforeseen circumstances.

Cloud possesses redundant infrastructure to form sure data is out there whenever and wherever you would like it. High availability and reliability are critical concerns for any sort of cloud solution.

Security and Compliance

Two significant concerns discussed when organizations believe cloud computing are data security and compliance with relevant regulatory authorities. Compromising each other’s data security isn’t profitable to anyone during a Community Cloud.

Users can configure various levels of security for his or her data. Common use cases:

the power to dam users from editing and downloading specific datasets.

Making sensitive data subject to strict regulations on who has access to Sharing sensitive data unique to a specific organization would bring harm to all or any the members involved.

What devices can store sensitive data.

Convenience and Control

Conflicts associated with convenience and control don’t arise during a Community Cloud. Democracy may be a crucial factor the Community Cloud offers as all tenants share and own the infrastructure and make decisions collaboratively. This setup allows organizations to possess their data closer to them while avoiding the complexities of a personal Cloud.

Less Work for the IT Department

Having data, applications, and systems within the cloud means you are doing not need to manage them entirely. This convenience eliminates the necessity for tenants to use extra human resources to manage the system. Even during a self-managed solution, the work is split among the participating organizations.

Environment Sustainability

In the Community Cloud, organizations use one platform for all their needs, which dissuades them from investing in separate cloud facilities. This shift introduces a symbiotic relationship between broadening and shrinking the utilization of cloud among clients. With the reduction of organizations using different clouds, resources are used more efficiently, thus resulting in a smaller carbon footprint.

CEH describes SQL injection testing as a core part of web application assessment. One of the first and safest validation techniques is using a tautology-based SQL injection payload, such as ' OR '1'='1. If the application concatenates user input directly into SQL queries, such an input will cause the query to always evaluate as true, often returning additional records such as multiple user profiles. This confirms the presence of SQL injection without causing destructive effects like dropping tables. Testing XSS does not validate SQL injection, brute-forcing credentials is unrelated, and directory traversal attacks target file path manipulation rather than backend queries. CEH emphasizes avoiding destructive queries and starting with non-intrusive injection payloads that reveal improper input sanitization, making ' OR '1'='1 the correct technique for confirming SQL injection vulnerabilities in URL parameters.

CEH teaches that ARP-based attacks vary in sophistication from basic poisoning to more specialized techniques such as switch port stealing. In environments where ARP poisoning defenses or inspection tools limit traditional attacks, attackers may exploit timing vulnerabilities in ARP reply behavior. Switch port stealing works by sending spoofed ARP replies at precisely the right moment—before the legitimate ARP response from the target host—causing the switch’s CAM table to update temporarily and associate the target’s IP address with the attacker’s MAC address. CEH emphasizes that switches trust the latest ARP update, so even brief timing windows enable partial packet interception. This is different from fully persistent ARP poisoning, which continuously overwrites ARP tables, and from passive sniffing, which cannot capture unicast traffic on a switched network. This attack is particularly useful when ARP spoofing is mitigated because it relies on opportunistic timing rather than full table poisoning. The intermittent nature of intercepted packets matches CEH’s description of switch port stealing behavior.

A multihomed firewall refers to a firewall with two or more network interfaces (NICs), each connected to different network segments. The purpose of a multihomed firewall is to allow filtering and segmentation of traffic between multiple network zones, such as:

External network (e.g., Internet)

Internal network (e.g., LAN)

To qualify as multihomed, the system must have at least two network interfaces. This allows it to sit between two networks and inspect/filter traffic passing through it.

Reference – CEH v13 Official Study Guide:

Module 13: Evading IDS, Firewalls, and Honeypots

Section: Firewall Architecture

Quote:

“A multihomed firewall is a system with two or more NICs connected to different networks, typically used to control traffic between internal and external networks. The minimum number of interfaces is two.”

Incorrect Options Explained:

A. 3 interfaces may be used in advanced setups (e.g., with a DMZ), but not the minimum.

B & C. 4 or 5 connections are not required unless designing more complex segmentation.

===========

Passive reconnaissance focuses on collecting intelligence without interacting with the target's systems. CEH materials emphasize reviewing publicly available information, including leaked documents, breach data, reports, or exposed metadata, as this yields internal network structure details while generating no detectable traffic. This method avoids triggering monitoring systems and aligns with stealth requirements for covert intelligence gathering.
