What is digital security?
Digital security is the set of practices and tools used to protect devices, accounts, data, and transactions against unauthorized access, fraud, loss, or alteration. It combines technology with behavior: keeping your phone updated and using technical protection matters, but verifying identities and requests is also part of the defense.

Scams and social engineering
Phishing, smishing, vishing, and social engineering describe ways of deceiving a person to obtain data, money, access, or installation.
Phishing
Phishing is impersonation designed to make someone reveal information, send money, install software, or approve access.
Understand the term →Smishing

Understand the term →Peer-to-peer payment scam
A peer-to-peer payment scam persuades someone to authorize a transfer under a false story.
Understand the term →Malicious software and apps
Malware is the broad term for malicious software. Spyware and ransomware are categories with different goals, while APKs and app permissions require their own source and access checks.
Malware
Malware is software designed to damage, disrupt, spy, steal, or obtain unauthorized access.
Understand the term →Spyware
Spyware collects information or tracks activity without the user’s informed consent.

Understand the term →APK
An APK is an Android application package used to install an app.
Understand the term →Fake app
A fake app imitates a real product or uses a deceptive identity.
Understand the term →Dangerous permissions
Dangerous permissions is a practical label for access that can expose sensitive data or device control when it is unnecessary or abused.
Understand the term →Links, sites, and networks
A URL, domain, page, and network are not the same thing. Evaluating the address and context reduces decisions based only on appearance.
Fake website
A fake website copies a legitimate organization or invents a business to steal credentials, identity information, or money.
Understand the term →Malicious link
A malicious link leads to a destination or action intended to harm the user.
Understand the term →Shortened URL

Understand the term →Unsecured Wi-Fi
Unsecured Wi-Fi allows connection without individual authentication or strong network access control.
Understand the term →Accounts and data
Data exposure, compromised credentials, and unauthorized account control are related situations, but they do not mean the same thing.
Data breach
A data breach occurs when information is accessed, disclosed, altered, or stolen without authorization.
Understand the term →Compromised credentials
Compromised credentials are usernames, passwords, tokens, keys, or recovery data that may be available to an unauthorized person.
Understand the term →Account takeover
Account takeover occurs when someone gains unauthorized control of an online account and may change recovery settings, send messages, or perform transactions.
Understand the term →Two-factor authentication
Two-factor authentication uses two distinct factors to verify a sign-in.
Understand the term →Real-time protection
Real-time protection checks selected activity while it happens and warns about threats covered by the product’s detection and permissions.
Understand the term →Try another search or select the “All” category.
How to use security terms carefully
These terms describe different layers. A data breach does not automatically mean an account takeover. An APK is not automatically malware. A clean URL result does not establish that a seller or payment request is legitimate.
Name the event precisely, then choose the matching response. Device threats need app and file review. Account compromise needs session and recovery controls. Fraud requires verification and rapid contact with the financial provider.
