Digital security is the protection of your digital identity - the network or Internet equivalent of your physical identity. Digital security includes the tools you use to secure your identity, assets and technology in the online and mobile world.

These tools include anti-virus software, Web services, biometrics and secure personal devices you carry with you every day. Secure personal devices such as a smart card-based USB token, the SIM card in your cell phone, the secure chip in your contactless payment card or e-passport are digital security devices because they give you the freedom to communicate, travel, shop, bank and work using your digital identity in a way that is convenient, enjoyable and secure.
