Definition
Meaning
The practice of protecting computer systems, networks, data, and programs from digital attacks, damage, or unauthorized access.
A broad discipline encompassing technology, processes, and practices designed to safeguard digital infrastructure, information, and operations from a wide range of threats, including hacking, malware, phishing, and espionage. It also involves incident response, risk management, and ensuring business continuity in the face of cyber incidents.
Linguistics
Semantic Notes
A compound noun formed from 'cyber-' (relating to computers/IT) + 'security'. It is a mass/uncountable noun; one does not typically say 'a cybersecurity' or 'cybersecurities'. The field is often referred to informally as 'infosec' (information security), though cybersecurity has a broader, more technical scope.

Memory Aids
Mnemonic
Imagine a CYBERnetic (robot) GUARD protecting a SECURE fort. CYBER-SECUR-ITY = the security guard for the cyber world.
Conceptual Metaphor
CYBERSECURITY IS WARFARE/DEFENCE (e.g., 'firewall', 'attack', 'breach', 'threat vector', 'defend', 'intrusion'). CYBERSECURITY IS PUBLIC HEALTH (e.g., 'virus', 'infection', 'patch', 'immunity', 'hygiene').
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque like 'кибербезопасность' being used in an overly literal, non-technical English context; 'cybersecurity' is the standard term. Do not confuse with general 'safety' (безопасность). The 'cyber-' prefix is specific to digital/computer systems.
Common Mistakes
- Spelling: 'cyber security' (two words) is less standard than the closed or hyphenated forms. Using it as a countable noun (e.g., 'We need a good cybersecurity'). Confusing it with 'physical security' or 'national security' without the digital context.

FAQ
Frequently Asked Questions
In modern American English, it is almost always one word: 'cybersecurity'. British English more frequently uses the hyphenated form 'cyber-security', but the one-word form is also accepted. The two-word form 'cyber security' is less standard.
They are closely related and often used interchangeably. However, 'information security' (infosec) is a broader term focused on protecting all information assets (physical and digital). 'Cybersecurity' is a subset specifically concerned with protecting digital/electronic systems, networks, and data from cyberattacks.
Yes, in attributive position (before a noun), it functions as a compound modifier. For example: 'cybersecurity risks', 'cybersecurity policy'. It is not typically used as a predicate adjective (e.g., 'The system is cybersecurity' is incorrect).
No. The prefix 'cyber-' originates from 'cybernetics' (the science of systems). While now dominantly associated with digital technology and the internet, it can appear in neutral terms like 'cyberculture' or 'cyberpunk'. However, in 'cybersecurity', the context is inherently protective and defensive against malicious activity.
