Certified Network Defender (CND): A complete guide

Certified Network Defender (CND) is a vendor-neutral complete network security certification.

The EC-Council CND certification designed to equip you with hands-on training to work in real-life circumstances, including network defense. You will acquire the technical skills needed to efficiently design a secure network with future threats into consideration. The Certified Network Defender (CND) certification emphasizes on creating Network Administrators skilled on defending, detecting, and taking actions to the threats across the network. Network administrators are commonly acquainted with network components, traffic, utilization and performance, network topology, the position of each system, security strategy, etc. A CND will have a basic knowledge of the actual set up of data transfer, software technologies, network technologies so that they perceive how networks operate, perceive what software is automating and how to interpret the subject material. Besides, network defense basics, the application of network security controls, perimeter appliances, protocols, VPN and firewall configuration, secure IDS, intricacies of network traffic signature, analysis, and vulnerability scanning are also included which will help the Network Administrator design better network security measures and effective incident response plans.\

 

This guide will examine the Certified Network Defender (CND) certification. We’ll look at what the CND is, the requirement for taking the exam, what the exam covers, the information covered in the CND training, and the benefits of becoming a CND. Furthermore, you will discover what career options CND holders have available to them. This guide provides a few examples of the jobs that may require applicants to hold this certification, including the average compensation. Earning a professional certification demonstrates a commitment to your profession and authenticates your knowledge and experience in your field. There are a wide variety of certifications available to professionals in any area of expertise. For students or anyone who has plenty of time to invest in their education, a degree from an accredited college or university is often the best option to advance their career. However, for working adults, the shorter duration of a certification program may be the most expeditious route to achieving their career goals. Certifications are essential for employers. Hiring managers use certifications as an easy way to set the minimum requirements for positions they are trying to fill. Job seekers use these professional credentials to indicate that they have the required level of knowledge and meet the minimum standards for the role.

 

What is a CND?

 

CND certification is appropriate for anyone who works in the network administration or cybersecurity fields in the capacity of a network administrator, network engineer, network security administrator, or security analyst. CND is for all cybersecurity operations and roles, and it is applicable for anyone looking to build a career in this domain. The EC-Council offers CND training and certification. It is a vendor-neutral network security certification program that provides an unbiased approach to learning secure networking practices, including analyzing and hardening computing systems commonly used in current IT infrastructures. The EC-Council organization certifies professionals in multiple technology and security skills and knowledge. Their stated mission is “to validate information security professionals who are equipped with the necessary skills and knowledge required in a specialized information security domain that will help them avert a cyber conflict, should the need ever arise.” The EC-Council has certified over 237,000 security professionals from private and public companies. They claim members working at IBM, Microsoft, the US Army, the FBI, and the United Nations. To address the unique needs of a post-pandemic, remote workforce, network environment, the CND training has been revamped and is now called CND v2. It has historically been the only program in the market that is 100% focused on network security and defense, and now it has been upgraded to accommodate more of today’s challenges. Mapped to NICE 2.0 Framework, CND v2 domains validate the holder in all vital network information and security areas. Building on the traditional cybersecurity approach of “Protect and Detect,” this certification teaches a more comprehensive model of “Predict, Protect, Detect, Respond.” Here are some distinguishing features of CND v2:

 

·         A practical and proactive approach to the fundamentals of threat intelligence

·         A focus on cloud security and IoT

·         Knowledge about latest technologies like SDN (Software Defined Network) and Kubernetes

·         Emphasis on AWS, Azure, and Google Cloud Platforms

·         A lab-intensive program, it provides first-hand experience

 

The EC-Council CND v2 is accredited, recognized, or endorsed by The American National Standards Institute (ANSI), The National Institute of Communication Finance (NICF), Government Communications Headquarters (GCHQ), and The Department of Defense (DoD).

 

Requirements for the CND exam

 

There are two options for those wishing to sit for the CND v2 certification examination. The candidate can attend an official network security training course offered by EC-Council or approved academic institutions. After completing the approved course, the candidate can challenge the exam without going through the application process. Or, the second option is to attempt the exam without official certification training, in which case, the candidate must have at least two years of work experience in the information security field. Candidates that have the required work experience can submit an eligibility application form along with a $100.00 non-refundable fee. Candidates choosing to take an official certification training course will learn the following tasks, processes, policies, and procedures. Candidates opting to rely on their work experience should evaluate their understanding of each of these areas before sitting for the exam.

 

·         Understanding network security management 

·         Learn basics of first response and forensics

·         Establishing network security policies and procedures 

·         Understanding indicators of Compromise, Attack, and Exposures (IoC, IoA, IoE)

·         Windows and Linux security administration

·         Building threat intelligence capabilities

·         Deploying and using risk assessment tools

·         Establishing Network Authentication, Authorization, Accounting (AAA)

 

CND certification exam

 

The CND v2 exam consists of 100 multiple-choice questions. Candidates can take up to four hours to complete any of the multiple versions of the exam. EC-Council has designed each version of the exam to provide the appropriate level of academic difficulty and real-world application. They beta test each new exam with a sample group of candidates under the guidance of a committee of subject matter experts. Each question is given a difficulty rating which contributes to the determination of a “cut score.” Cut scores or the mark above which a candidate must score to pass the exam will vary for the different versions administered. This cut score can range from 60% to 85%, depending on the difficulty rating of the questions on that exam. Test creators write each question to ensure that candidates understand each of the 20 modules, which form the basis for the training. These modules are:

 

·         Network Attacks and Defense Strategies 

·         Administrative Network Security 

·         Technical Network Security 

·         Network Perimeter Security 

·         Endpoint Security-Windows Systems 

·         Endpoint Security-Linux Systems 

·         Endpoint Security- Mobile Devices 

·         Endpoint Security-IoT Devices 

·         Administrative Application Security 

·         Data Security Enterprise 

·         Virtual Network Security Enterprise 

·         Cloud Network Security 

·         Enterprise Wireless Network Security 

·         Network Traffic Monitoring and Analysis 

·         Network Logs Monitoring and Analysis 

·         Incident Response and Forensic Investigations 

·         Business Continuity and Disaster Recovery 

·         Risk Anticipation with Risk Management 

·         Threat Assessment with Attack Surface Analysis 

·         Threat Prediction with Cyber Threat Intelligence

 

Understanding what information the exam covers will help a candidate prepare adequately. As an example of the types of questions you can expect, here is one of the EC-Council sample questions for the CND v2 exam:

 

An IT company has just been hit with a severe external security breach. To enhance the company’s security posture, the network admin has decided first to block all the services and then individually enable only the necessary services. What is such an Internet access policy called?

 

·         Prudent Policy

·         Permissive Policy

·         Promiscuous Policy

·         Paranoid Policy

 

If a candidate does not successfully pass an EC-Council exam, they can purchase an ECC Exam center voucher to retake the exam at a discounted price. If a candidate cannot pass the exam on the first attempt, no waiting period is required to attempt the exam for the second time. If a candidate cannot pass the second attempt, a waiting period of 14 days is required before attempting the exam for the third time. A candidate is not allowed to take a given exam more than five times in 12 months, and EC Council will impose a waiting period of 12 months before the candidate will be allowed to attempt the exam for the sixth time.

 

CND training courses

 

ECC designed the Network Defense training program to instruct network administrators in network security technologies and operations and teach students how to master the core skills to build a solid cybersecurity skillset. Students learn to examine the network traffic that traverses enterprise networks at the packet and binary level and build a solid knowledge of the lowest layers of the network stack. CND candidates will learn to master TCP/IP and essential UNIX and Linux used by security professionals. Offered through ECC’s MasterClass program, CND v2 was created to help candidates build a solid security foundation and introduce them to vulnerability assessment and the hacking methodology so they will be ready to pursue more advanced security training such as the Certified Ethical Hacker. ECC offers several options for CND v2 training courses. The self-study course, called iLearning, is a self-directed program utilizing a streaming video format, and iWeek is an instructor-led live online option. ECC CND v2 “in-person” training is provided by authorized training partners and is offered in many locations. These hands-on classes provide the benefit of learning with peers and gaining real-world skills in a team environment. EC-Council Academia partners offer training at colleges and universities, often as part of a degree program.
