CYBERSECURITY GUIDE FOR DEVELOPERS AND NOVICE SPECIALISTS
How to become a cybersecurity specialist, whether you need to be able to program for this, and what tools and certificates you will need.
Elon Musk announced in X that his company xAI has launched a preliminary test version of the Grok chatbot. While the neural network is available to a limited number of users, but you can register and get in line.
What is cybersecurity?
Cybersecurity is the activity of protecting information in its various aspects, ranging from database protection to the protection of company management negotiations.
Sometimes it is believed that cybersecurity is a direction that applies only to technology. But this is not so: technologies do not work without processes and people who support them, and processes do not work without technologies. They are interconnected.
protection of web applications,
protection of networks,
protection of industrial systems,
compliance with legislation on information security,
computer forensics
and many others.
In each of these areas, you can develop over the years and find new and interesting tasks for yourself.
Around the world, the burden on information security services in state-owned companies, banks, media companies, and telecoms has now increased. Cybersecurity is now in focus not only at the corporate, but also at the state level.
How to become cybersecurity specialists?
Those who just attend lectures and do not study additionally will not be able to become good specialists immediately after graduation, because cybersecurity, like all information technologies, is actively developing every year, and training programs often stand still.
Also, before protecting something, you need to understand how it works. Basic knowledge of Computer Science is just a must-have: operating systems, protocols, understanding of the stack of web technologies, Internet devices, basic network protocols. It's easy to get the necessary knowledge now, because there are a lot of free and paid sites with high—quality courses on the Web - the same famous CS50 course from Harvard University.
Choose a direction
It is better for a future specialist to choose one direction of cybersecurity while studying at a university in order to invest all his energy in it. Now the areas of cybersecurity are very highly segmented and a specialist in one area may not understand another at all. Therefore, you need to decide at the start what exactly you want to do: look for vulnerabilities, safely configure network equipment or protect web systems - and build a training plan based on this.
Prepare for certification
It is desirable for a specialist in finding vulnerabilities in web technologies to obtain international certification, for example, OSCP or CEH for "white" hackers. With her, it will be easier for him to find a job in many companies around the world. They have a clear program that has been honed over the years, constantly modified, improved. This program also includes modern vulnerabilities — that is, it is relevant, modern and has a practical orientation.
If you have set yourself the goal of getting certified, you need to prepare. There are many courses that help to prepare for it. If you don't have enough knowledge of web programming, you can get JavaScript or PHP. There are also certifications for network technologies, including network security (for example, from Cisco — CCNP Security).
Master programming and explore vulnerabilities
Vulnerabilities are found all the time, because software products are complex, developed by hundreds of people and it is very difficult to track all dependencies. Most vulnerabilities are holes that allow you to run arbitrary code, read data without proper authority, intercept and decrypt traffic, execute arbitrary requests in the browser without the user's knowledge, redirect traffic to another source, and so on.
It is important to understand what types of vulnerabilities exist in general and how they can be eliminated. To do this, you often have to communicate with developers. But I personally have to program infrequently — although sometimes I need to look at someone else's code during releases in search of vulnerabilities.
