Companies in various sectors, such as energy, transportation, retail, and manufacturing, use digital systems and high-speed connectivity to provide efficient customer service and conduct affordable business operations. Just as these organizations secure their physical assets, they must also secure their digital assets and protect their systems from any unintended access. A hack occurs, obtaining unauthorized access to a computer system, network, or connected facilities is called a "cyberattack" if it is intentional. A successful cyber attack results in confidential data being revealed, stolen, deleted, or altered. Cybersecurity measures defend against cyberattacks and provide the following benefits: Prevent violations or reduce the cost of their consequences Organizations that implement cybersecurity strategies minimize the undesirable consequences of cyberattacks that may affect companies' reputation, financial position, business operations, and customer trust. For example, companies activate disaster recovery plans to contain potential interventions and reduce the duration of disruption to business operations. Ensure compliance with regulations Companies in specific areas and regions must comply with regulatory requirements in order to protect sensitive data from potential cyber risks. For example, companies operating in Europe must comply with the General Data Protection Regulation (GDPR), which expects organizations to take appropriate cybersecurity measures to ensure data privacy. Reducing evolving cyber threats As technologies change, new forms of cyber attacks are emerging. Criminals use new tools and devise new strategies to access the system without permission. Organizations are adopting and updating cybersecurity measures to keep pace with new and evolving digital attack technologies and tools.
