As traditional network security boundaries disappear, a defense-in-depth security approach centered on data and identity and centered on "human factors" is gaining widespread acceptance in the industry.
So, for developers who have just entered the network security industry and want to get started quickly, it is best to quickly become familiar with modern network security technology stacks and methods through the process of developing various "small" products.
Uncle Dun recommends 5 easy-to-use and effective network security products suitable for beginners to develop.
Let's give two examples first. For example, you want to develop a web application firewall.
The main steps are: First, you need to define the security policy of your application, including which types of requests should be allowed, which should be blocked, and how to detect and prevent potential attacks;
2. Ensure that only authorized users can access your application. This can be achieved by using authentication and authorization mechanisms such as role-based access control (RBAC).
3. Validate and filter all input to prevent cross-site scripting attacks (XSS), SQL injection and other common security vulnerabilities. Input validation and filtering can be achieved using techniques such as regular expressions, whitelist filtering, and encoding escaping;
4. Implement monitoring and logging mechanisms to promptly detect potential attacks and perform corresponding response and repair work. Tools and platforms can be used to collect and analyze log data and set up alerts and notification mechanisms.
5. Regularly update your applications and related software libraries to stay in sync with the latest security patches. At the same time, track known vulnerabilities and security risks and fix them in a timely manner.
6. Conduct regular security testing and vulnerability scanning to discover potential security holes and weaknesses. You can use automated tools or hire security experts to conduct a security assessment.
7. Develop emergency response plans to respond to possible security incidents and attacks. Including stages such as pre-preparation, emergency response, recovery and follow-up analysis.
Through this whole process, you will learn a lot.
The second one develops a password manager
This manager can store and generate strong passwords for various accounts, and you'll learn a lot from developing them.
First you need to carefully consider what features your password manager needs to provide, such as saving and encrypting passwords, generating secure passwords, auto-filling forms, etc. You also need to determine what data you need to store, such as user information, passwords, website/application information, etc., and design the corresponding database table structure. Then you have to create a user interface that is easy to use and intuitive. And use strong encryption algorithms to encrypt user passwords and ensure that passwords are secure during storage and transmission.
It is also necessary to provide a password generator that can generate strong passwords and meet user requirements, such as length, character type, etc. Finally, you have to perform security testing to ensure that your application is vulnerability-free and can protect privacy and data security.
Third Build a Phishing Awareness Game
You can create your own interactive game to teach your friends phishing techniques and help them identify and avoid phishing attempts. And you can also lock an individual and track and monitor the partner: "whether to check the email", "whether to click the link", "whether to enter data", and display it graphically, which is very intuitive. Through simulated scenarios, your friends can also learn to identify suspicious emails, websites, and messages, minimizing the risk of becoming a target for cybercriminals.
The fourth malware detection app
Develop an application that uses machine learning algorithms to detect and isolate malware on computers and mobile devices. This program primarily protects users from viruses, ransomware, and other malware that can steal data and privacy.
The fifth social engineering defense simulator
Design a simulator that presents users with various social engineering scenarios, such as phishing calls/emails or scam scripts. The simulator should introduce users to common social engineering tactics and help them develop strategies to identify and resist cyber attacker manipulation and attacks.
The above-mentioned projects are relatively low in complexity, and at the same time have high applicability and practicality, and are all key functions of enterprise network security.
You will continuously expand and improve your network security technology, knowledge, experience and awareness during the development process, laying a good foundation for developing more complex network security tools or defending against advanced security threats in the future.
Finally
In order to help everyone learn network security better, the editor has prepared an introductory/advanced learning material for network security for everyone. The content in it is all notes and materials suitable for beginners with zero basic knowledge. It can be understood even if you don’t know programming.
