Introduction In light of the rapid digital development and the increasing reliance on technology and the internet across various aspects of life, cybersecurity has emerged as one of the most important core disciplines of the modern era. Digital information and data have become direct targets of cyberattacks, which has made it necessary to highlight this vital field and its role in protecting individuals and institutions. What Is Cybersecurity? Cybersecurity is a science and technology aimed at protecting computer systems, networks, and data from cyber threats and attacks such as hacking, information theft, and digital fraud. This field relies on a set of measures and policies that ensure the confidentiality, integrity, and availability of information, enabling the safe use of technology. Social Engineering (The Most Widespread and Dangerous Attack): Social engineering is considered one of the most widespread and dangerous cyberattacks worldwide, as it relies on exploiting the human factor rather than directly targeting technical systems. In this type of attack, the attacker psychologically manipulates the victim and persuades them to disclose sensitive information such as passwords or personal data. These attacks are often carried out through phishing messages or identity impersonation. The Importance of Cybersecurity Awareness The importance of cybersecurity lies in its role as the first line of defense against cybercrime, especially attacks that target users who lack awareness of digital risks. Spreading security awareness and continuous education helps reduce the success of attacks and protects personal and institutional data from unlawful exploitation. Cybersecurity and the Future of the Digital World With the increasing number of cyber threats, cybersecurity has become an essential element in maintaining the stability of digital systems and ensuring safe technological progress. It is also considered one of the most promising fields, playing a pivotal role in protecting digital societies and building a safer future. Conclusion In conclusion, cybersecurity represents an inevitable necessity in the digital age, particularly in confronting social engineering attacks that exploit gaps in human awareness. This highlights the importance of combining technical solutions with the promotion of cybersecurity culture to build a safe and sustainable digital environment.
