Cybersecurity
Cybersecurity is the practice of protecting systems, networks, and data from unauthorized access, damage, and disruption.
Overview
Security combines technology, processes, and people. Firewalls, encryption, and monitoring tools matter, but so do everyday habits such as using strong authentication, keeping software updated, and recognizing suspicious messages.
No system is completely risk-free. Good security focuses on reducing the most likely and most damaging risks, detecting problems quickly, and being prepared to recover.
At a Glance
Combines technology, process, and people
Focuses on the most significant risks
Requires ongoing updates and awareness
Includes planning for recovery
Key Concepts
The three core goals of protecting information and systems.
Requiring more than one form of verification to sign in.
Deceptive messages designed to steal information or install malicious software.
Encoding data so only authorized parties can read it.
Applying updates that fix known security vulnerabilities.
Keeping protected copies of data so it can be restored after an incident.
Common Uses
Typical applications across organizations of different sizes and industries.
Account & identity protection
Securing sign-ins and managing who has access.
Device & network security
Protecting computers, phones, and connections.
Data protection
Safeguarding sensitive and personal information.
Incident response
Preparing to detect, contain, and recover from problems.
Before You Adopt
Use these questions to evaluate tools, plans, and proposals related to cybersecurity.
Which systems and data matter most, and who can access them?
Is multi-factor authentication enabled for important accounts?
Are software and devices kept up to date?
Are backups tested and stored separately from the original data?
Do people know how to recognize and report suspicious activity?
Is there a plan for responding to and recovering from an incident?
