CyberSecurity

  • Computer Security, CyberSecurity or Information Technology Security (IT Security) is the protection of computer systems from theft or damage to their hardware, software or electronic data, as well as from disruption or misdirection of the services they provide. [Wikipedia]

    • CyberSecurity is a subset of Information Security. Information Security, sometimes shortened to InfoSec, is the practice of preventing unauthorized access, use, disclosure, disruption, modification, inspection, recording or destruction of information. [Wikipedia]

  • CyberSecurity refers to a set of techniques used to protect the integrity of networks, programs and data from attack, damage or unauthorized access. [PaloAlto Networks]

  • CyberSecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users; or interrupting normal business processes. Implementing effective cybersecurity measures is particularly challenging today because there are more devices than people, and attackers are becoming more innovative. [Cisco]

  • CyberSecurity is strengthening the security and resilience of cyberspace.

    • CyberSecurity at the federal level includes: Combating Cyber Crime, Securing Federal Networks, Protecting Critical Infrastructure, Cyber Incident Response, Cyber Safety, Cybersecurity Governance, Cybersecurity Insurance, Cybersecurity Jobs, Cybersecurity Training & Exercises, Information Sharing, Stakeholder Engagement and Cyber Infrastructure Resilience.

    • Cyberspace and its underlying infrastructure are vulnerable to a wide range of risk stemming from both physical and cyber threats and hazards. Sophisticated cyber actors and nation-states exploit vulnerabilities to steal information and money and are developing capabilities to disrupt, destroy, or threaten the delivery of essential services. A range of traditional crimes are now being perpetrated through cyberspace. This includes the production and distribution of child pornography and child exploitation conspiracies, banking and financial fraud, intellectual property violations, and other crimes, all of which have substantial human and economic consequences.

    • Cyberspace is particularly difficult to secure due to a number of factors: the ability of malicious actors to operate from anywhere in the world, the linkages between cyberspace and physical systems, and the difficulty of reducing vulnerabilities and consequences in complex cyber networks. Of growing concern is the cyber threat to critical infrastructure, which is increasingly subject to sophisticated cyber intrusions that pose new risks. As information technology becomes increasingly integrated with physical infrastructure operations, there is increased risk for wide scale or high-consequence events that could cause harm or disrupt services upon which our economy and the daily lives of millions of Americans depend. In light of the risk and potential consequences of cyber events, strengthening the security and resilience of cyberspace has become an important homeland security mission.
