Learn Networking
If you're looking to become a network security engineer, there are a few things you should know. Networking is the process of linking computers and devices together so that they can communicate with each other. It's an important part of any network security engineer's job to understand how networking works and how it can be used to protect data and systems.
Learn Hacking
As a network security engineer, you will be responsible for ensuring the security of a company's computer network. This includes protecting the network from attacks, as well as ensuring that data is not accessed without authorization. In order to do this, you will need to have a strong understanding of hacking techniques.
There are a variety of resources available to help you learn about hacking. You can start by reading books or articles on the subject. There are also many online courses that can teach you the basics of hacking. Once you have a good understanding of the basics, you can then move on to more advanced topics.
In addition to learning about hacking techniques, it is also important to keep up with new security threats. This can be done by subscribing to security mailing lists and following security blogs. By staying up-to-date on new threats, you will be better able to protect against them.
Learn Software Development and IT Security
If you want to become a network security engineer, you will need to learn software development and IT security. There are many resources available online and in libraries that can help you learn these skills.
One way to learn software development is to take an online course. Many websites offer courses that teach the basics of programming and software development. These courses can be taken at your own pace and usually include exercises and quizzes to help you understand the material.
Another way to learn software development is to read books or articles on the subject. There are many books available that cover the basics of programming and software development. You can also find articles on the subject by searching for "software development" on your favorite search engine.
To learn IT security, you can take an online course or read books and articles on the subject. Many online courses cover topics such as cryptography, network security, and risk management. You can also find books on these topics in your local library or bookstore.
Network Security Tools
There are a few key tools that every network security engineer should be familiar with. These tools can help you assess and improve your network’s security posture.
Nmap
Nmap is a network exploration and security auditing tool. It can be used to identify open ports on systems, as well as system dependencies. You can read Network Scanning: The Official Nmap Project Guide to Network Discovery and Security Scanning book by Gordon Fyodor Lyon.
Wireshark
Wireshark is a packet capture tool that can be used to troubleshoot networking issues. It can also be used to assess traffic patterns on a network.
Nessus
Nessus is a vulnerability scanning tool that can be used to identify potential security risks on systems and networks. You can read Mastering Nessus: A Comprehensive Guide to Cybersecurity Assessment book by Avyaan Arenson.
Metasploit
Metasploit is a exploitation framework that can be used to exploit vulnerabilities on systems. It can also be used for penetration testing purposes.
Network Infrastructure
The network infrastructure of an organization is the backbone of its security. A well-designed and implemented network infrastructure can make the difference between a secure and an insecure organization. In this section, we will discuss the components of a network infrastructure and how to design and implement a secure network infrastructure.
The first component of a network infrastructure is the physical network. The physical network consists of the devices that are used to connect the various parts of the network. These devices include routers, switches, firewalls, and other hardware. The physical layout of the network also plays a role in security. For example, if the router is placed in a room with no windows, it is more difficult for an attacker to physically access the router.
The second component of a network infrastructure is the logical network. The logical network consists of the software that is used to manage the traffic on the physical network. This software includes routing protocols, firewall rules, and other software configurations. The logical layout of thenetwork also affects security. For example, if all traffic between two parts of the network must go through a central server, then that server becomes a single point of failure for the entire system.
A well-designed and implemented network infrastructure can be secure even if individual components are not perfectly secure. For example, even if a router is vulnerable to attack, it can be placed behind a firewall so that only authorized traffic can reach it.
