Practices for protecting systems, data, and identities from threats. This covers everything from personal account hygiene (strong passwords, MFA, email aliases) to organizational concerns like Supply Chain Attacks, Data Breaches, and access control.
Good security is mostly about reducing your attack surface and making the cost of compromising you higher than the value of what an attacker would get. For individuals, that means: use a password manager, enable multi-factor authentication everywhere, keep software updated, and be skeptical of unexpected messages (especially ones that create urgency).
The landscape changes constantly, particularly with AI-powered threats that can generate convincing phishing at scale and clone voices from a few seconds of audio. Staying informed matters as much as staying locked down.
