 [HTTPS](https://brave.com/glossary/https/)
 HTTPS (HyperText Transfer Protocol, Secure) is a secure version of HTTP, the standardized method by which Web browsers and Web servers talk to each other over a network. HTTPS generally protects data in transit between a server (where a website or app "lives") and the client (the phone or computer) you're browsing from. Some browsers now automatically upgrade sites to HTTPS, or will warn you if HTTPS isn't available; sites where HTTPS is not available should be visited with caution.

+[Information security](https://brave.com/glossary/information-security/)
+Information security refers to the tools and procedures an organization adopts to protect information and associated systems against unauthorized access, use, disclosure, disruption, modification, or destruction. All organizations deal with some type of information, from intellectual property to classified documents to the data of users or customers. Keeping this information safe can involve technology, physical security, and more.
 [IP address](https://brave.com/glossary/ip-address/)
 An Internet Protocol (IP) address is a numerical label (like 203.0.113.43) that identifies a device on a network, and allows computers to talk to each other. Any device on any network will need an IP address so it can receive data from other devices; the IP address is how the network gets data to the right place. Some IP addresses are public, while others are private. Sometimes, your IP address can be used to identify and track you across sites and apps.

+[Terms of service](https://brave.com/glossary/terms-of-service/)
+Terms of service (or ToS) are a legal agreement between a service provider and a user of the service. The service may be a website, app, or other software. Generally, the user must agree to ToS before they can access the service. Primarily, ToS protects the service provider and the service from abuse or theft by users. But these terms can also include clauses that secure a user's permission for the service provider to engage in other activities.
 [Third-party ad](https://brave.com/glossary/third-party-ad/)
 A third-party ad is a Web ad whose content is loaded from a different domain than the page showing the ad. The domain is the part of the URL after the "://" and before the next slash. For example, the domain of this page's URL is "brave.com." The opposite of a third-party ad is a first-party ad, which is loaded from the same domain as the page showing the ad.
