Cybersecurity is crucial in the modern age due to the increasing reliance on digital systems and data. It protects sensitive information from unauthorized access, cyberattacks, and data breaches, which can lead to financial loss, identity theft, and reputational damage. As businesses and individuals store vast amounts of data online, cybersecurity measures like **encryption**, **firewalls**, and **multi-factor authentication** are essential for safeguarding against threats. Effective cybersecurity also ensures the integrity and availability of digital services, maintains trust in online transactions, and supports national security. As cyber threats evolve, robust cybersecurity practices are vital for protecting digital infrastructure and maintaining privacy.
