DNS
turns domain names into IP addresses, which browsers use to load internet pages.
DOMAIN NAME SYSTEM (DNS)
(protected extensible authentication protocol) is a security protocol used to better secure WiFi networks.
An arrangement whereby a secure, apparently private network is achieved using encryption over a public network, typically the internet.
VIRTUAL PRIVATE NETWORK (VPN)
providing answers to recursive DNS nameservers about where specific websites can be found/ The authority for its zone. It queries and is queried by other name servers in the DNS.
AUTHORITATIVE DNS SERVER
a network protocol that enables the secure transfer of data from a remote client to a private enterprise server by creating a virtual private network (VPN) across TCP/IP-based data networks.
Point-to-Point Tunneling Protocol (PPTP)
a physical or logical subnet that separates a local area network (LAN) from other untrusted networks -- usually, the public internet.
Demilitarized zone (DMZ)
the temporary storage of information about previous DNS lookups on a machine's OS or web browser.
DNS CACHE
a common protocol used in Virtual Private Network (VPN) connections. The protocol was developed by Microsoft, so it's more common in a Windows environment than Linux.
Secure Socket Tunneling Protocol (SSTP)
a way to move packets from one network to another.
TUNNELING
happens when fake information is entered into the cache of a domain name server, resulting in DNS queries producing an incorrect reply, sending users to the wrong website.
DNS POISONING
a point-to-point protocol authentication method that uses passwords to validate users.
Password Authenticator Protocol (P.A.P)
a local or restricted communications network, especially a private network created using World Wide Web software.
INTRANET
a set of specifications that extend the DNS protocol by adding cryptographic authentication for responses received from authoritative DNS servers.
DNS SECURITY EXTENSION (DNSSEC)
a challenge and response authentication method that Point-to-Point Protocol (PPP) servers use to verify the identity of a remote user.
Challenge-Handshake Authentication Protocol
(CHAP)
an intranet that can be partially accessed by authorized outside users, enabling businesses to exchange information over the internet securely.
EXTRANET
