Cybersecurity is the protection of internet-connected systems, including hardware, software and data, from cyberattacks. In a computing context, security comprises cybersecurity and physical security -- both are used by enterprises to protect against unauthorized access to data centers and other computerized systems. Information security, which is designed to maintain the confidentiality, integrity and availability of data, is a subset of cybersecurity.
Apps are generally downloaded from application distribution platforms which are operated by the owner of the mobile operating system, such as the App Store (iOS) or Google Play Store.
One of the most problematic elements of cybersecurity is the constantly evolving nature of security risks. The traditional approach has been to focus resources on crucial system components and protect against the biggest known threats, which meant leaving components undefended and not protecting systems against less dangerous risks. To deal with the current environment, advisory organizations are promoting a more proactive and adaptive approach. The National Institute of Standards and Technology (NIST), for example, recently issued updated guidelines in its risk assessment framework that recommend a shift toward continuous monitoring and real-time assessments. Version 1.1 of the Framework for Improving Critical Infrastructure was released in April 2018. The voluntary cybersecurity framework, developed for use in the banking, communications, defense and energy industries, can be adopted by all sectors, including federal and state governments. President Donald Trump issued an executive order mandating that federal agencies adopt the NIST Cybersecurity Framework (NIST CSF) in May 2017. As a result of security risks, investments in cybersecurity technologies and services are increasing. In 2017, Gartner predicted that worldwide spending on information security products and services would reach $83.4 billion -- a 7% increase from 2016 -- and that it would continue to grow to $93 billion by 2018.
