Today in a fast-growing digital world, threats are more complex, and intricate for any citizen, business entity or even a country to fight and overcome. Contemporary legislation tends to fail at accommodating new technology trends and, more importantly, modern cyber threats. This paper also analyses various topical threats related to AI, IoT, and blockchain such as using them for cyberattacks in further detail. It measures the level of applicability of modern legal instruments in the fight against cyber security challenges in relation to several arguments such as jurisdiction conflict; privacy issues; and lack of effective collaboration across borders. Founded on literature review and comparison of cases, this paper presents recommendations for improvement of the legislation, international cooperation and measures of adaptability that will improve the situation dealing with the new cyber threats. The results point to the necessity of 'anticipatory' changes in legal terms for the sphere of digital security as a way for the post-industrial society to be on a path toward new safety within the context of emerging dangers.
