What is Cybersecurity?
Cybersecurity is the practice of protecting critical systems and sensitive information from digital attacks. Also known as information technology (IT) security, cybersecurity measures are designed to combat threats against networked systems and applications, whether those threats originate from inside or outside of an organization.
The cybersecurity field can be broken down into several different sections, the coordination of which within the organization is crucial to the success of a cybersecurity program.
Critical Infrastructure Security
Practices for protecting the computer systems, networks, and other assets that society relies upon for national security, economic health, and/or public safety. The National Institute of Standards and Technology (NIST) has created a cybersecurity framework to help organizations in this area, while the U.S. Department of Homeland Security (DHS) provides additional guidance.
Security measures for protecting a computer network from intruders, including both wired and wireless (Wi-Fi) connections.
Processes that help protect applications operating on-premises and in the cloud. Security should be built into applications at the design stage, with considerations for how data is handled, user authentication, etc.
Specifically, true confidential computing that encrypts cloud data at rest (in storage), in motion (as it travels to, from and within the cloud) and in use (during processing) to support customer privacy, business requirements and regulatory compliance standards.
Data protection measures, such as the General Data Protection Regulation or GDPR, that secure your most sensitive data from unauthorized access, exposure, or theft.
Building security awareness across the organization to strengthen endpoint security. For example, users can be trained to delete suspicious email attachments, avoid using unknown USB devices, etc.
Disaster Recovery / Business Continuity Planning
Tools and procedures for responding to unplanned events, such as natural disasters, power outages, or cybersecurity incidents, with minimal disruption to key operations.
Common Cyber Threats
The latest cybersecurity threats are putting a new spin on “known” threats, taking advantage of work-from-home environments, remote access tools, and new cloud services. These evolving threats include:
