Today, as the world increasingly becomes virtual reality, the problem of protecting personal and commercial information has become particularly acute. That’s why cybersecurity professionals are one of the most sought in the job market. This article will consider
Cybersecurity – what is it?
We live in a time when information can be a weapon or a way of manipulation if it falls into the hands of strangers. Confidentiality is a difficult task today, and sometimes it even seems an illusion. Along with a number of conveniences (online shopping, online utilities, online financial systems for entrepreneurs, etc.) there is a need to protect countless amounts of data. And state databases should not be forgotten either. All of this is a huge amount of information and a lot of computer systems that need to be protected and that need to be handled properly. Every year the percentage of digitalization in our lives will grow. That is why the role of cybersecurity as science will only grow every year.
Cybersecurity is the process of applying security measures to ensure the confidentiality, integrity, and availability of data. It is designed to protect data at the stage of their exchange and storage. Such security measures include access control, training, audit, and risk assessment, testing, management, and authorization security.
The terms “Cybersecurity” and “information security” are not synonymous. If information security focuses only on the storage of information, then the concept of “cybersecurity” is larger and covers not only the issue of data storage but also computer systems and the digital environment in general.
What should a cybersecurity specialist know?
The main task of a cybersecurity specialist is to ensure the protection of information of the enterprise, country, or citizens. Their job is to ensure the smooth operation of software for the protection of enterprise information, debugging, and maintaining the operation of hardware – in simple terms; they must be well versed in the device and operation of computers and computer networks. Also, each specialist must be able to write their own software specific to this particular organization, and if necessary, create an antivirus.
A good cybersecurity engineer will always be able to repel any hacker attack on the object entrusted to him, and a very good specialist will never allow this attack, blocking all access channels in advance.
Skills for work
Every cybersecurity engineer should have the following capabilities:
- Be able to program
- Read the code, revealing hidden sources of outside intrusion
- Understand the device of the popular computer “iron”
- Have analytical skills, calculating in advance the consequences of changes to the code
- Promptly assess threats and identify their sources
- Be able to work with large amounts of data
- Understand the principles of various cyberattacks and know-how to defend against them
- Know-how web layout works
- Be familiar with databases, in particular, with SQL
General responsibilities
Depending on the company, the set of responsibilities differs, but the most common areas of responsibility assigned to the average cybersecurity engineer can be distinguished:
- Planning, implementation, monitoring, and adjustment of measures aimed at improving safety;
- Solving problems related to security and network;
- Timely response to security breaches in systems and/or networks;
- Implementation of correct security measures to protect confidential information and IT equipment;
- Change control;
