EAP-TLS
Kerberos SESAME Active Directory
The Application layer uses protocols that are implemented within applications and services. While applications provide people with a way to create messages and Application layer services establish an interface to the network, protocols provide the rules and formats that govern how data is treated.
Answer: The Authenticated Header (AH) In the IPSec protocol the only traffic that is unencrypted is the (AH). In other words, it only signs the traffic to retain its authentication & integrity, but no privacy.
there are many ways but some which are economical also are: have a duplicate data or back up on other disk use quality server service which can provide data in case of crash don't use external device on main system like pendrivce
It provides protection from viruses, hackers, online fraud, identity theft and other anti viruses. This software will provide security for the whole family.

In best case it should be able to provide to AAA - authentication, accounting and authorization. But you will need to use the WPA2-Enterprise security type.
CallbackAuthenticationAnswer Explanation: To increase dial-in security, you should implement callback and authentication. Network hosts that allow modem dial-in can present a security risk since they provide a way into the network that bypasses firewalls. To increase dial-in security, you should use a secure authentication protocol that requires a username and password.
IPSec is a set of IP extensions that provide security services, such as encryption,authentication, and data integrity. IPSec is typically used with a VPN.

The Windows operating systems implements a default set of authentication protocols-Kerberos, NTLM, TLS/SSL, Digest, and PKU2U-as part of an extensible architecture. In addition, some protocols are combined into authentication packages such as the Credential Security Support Provider (CredSSP), Negotiate, and Negotiate Extensions. These protocols and packages enable authentication of users, computers, and services; the authentication process, in turn, enables authorized users and services to access resources in a secure manner. Windows authentication protocols are conventions that control or enable the connection, communication, and data transfer between computers in a Windows environment by verifying the identity of the credentials of a user, computer, or process. The authentication protocols are security support providers (SSPs) that are installed in the form of dynamic-link libraries (DLLs). Negotiate Microsoft Negotiate is an SSP that acts as an application layer between the Security Support Provider Interface (SSPI) and the other SSPs. When an application calls into SSPI to log on to a network, it can specify an SSP to process the request. If the application specifies Negotiate, Negotiate analyzes the request and selects the best SSP to handle the request based on the configured security policy. Currently, the Negotiate SSP selects either the Kerberos or NTLM protocol. Negotiate selects the Kerberos protocol unless it cannot be used by one of the systems involved in the authentication or if the client application did not provide a target name as a service principal name (SPN), a user principal name (UPN), or a NetBIOS account name. Otherwise, Negotiate will select the NTLM protocol. A server that uses the Negotiate SSP can respond to client applications that specifically select either the Kerberos or NTLM protocol. However, a client application must first query the server to determine if it supports the Negotiate package before using Negotiate. (Negotiate is supported on Windows operating systems beginning with Windows Server 2003 and Windows XP.) A server that does not support Negotiate cannot always respond to requests from clients that specify Negotiate as the SSP Kerberos :The Kerberos version 5 (v5) authentication protocol provides a mechanism for authentication-and mutual authentication-between a client and a server, or between one server and another server NTLM The NTLM version 2 (NTLMv2) authentication protocol is a challenge/response authentication protocol. NTLM is used when exchanging communications with a computer running Windows NT Server 4.0 or earlier. Networks with this configuration are referred to as mixed-mode. NTLM is also the authentication protocol for computers that are not participating in a domain, such as stand-alone servers and workgroups. Negotiate Extensions NegoExts (NegoExts.dll) is an authentication package that negotiates the use of SSPs for applications and scenarios implemented by Microsoft and other software companies. Pku2u.dll is one of the supported SSPs that is installed by default, and developers can create custom providers. PKU2U The PKU2U protocol in Windows 7 and Windows Server 2008 R2 is implemented as an SSP. The SSP enables peer-to-peer authentication, particularly through the Windows 7 media and file sharing feature called Homegroup, which permits sharing between computers that are not members of a domain. Credential Security Support Provider Windows Vista introduced a new authentication package called the Credential Security Support Provider (CredSSP) that provides a single sign-on (SSO) user experience when starting new Terminal Services sessions. CredSSP enables applications to delegate users' credentials from the client computer (by using the client-side SSP) to the target server (through the server-side SSP) based on client policies TLS/SSL The TLS/SSL protocols are used to authenticate servers and clients, and to encrypt messages between the authenticated parties. The TLS/SSL protocols, versions 2.0 and 3.0, and the Private Communications Transport (PCT) protocol are based on public key cryptography. The secure channel (Schannel) authentication protocol suite provides these protocols. All Schannel protocols use a client/server model and are primarily used for Internet applications that require secure Hypertext Transfer Protocol (HTTP) communications Digest The Digest authentication protocol is a challenge/response protocol that is designed for use with HTTP and Simple Authentication Security Layer (SASL) exchanges. These exchanges require that parties requesting authentication must provide secret keys.

Internet protocols or web protocols provide a basis of data volumes across a wide range of networks. This includes the security of data transported or routed, authenticating client servers, ensuring data integrity and securing data privacy.

Casinos have strict security protocols in place to prevent robberies and theft. For instance, they use an advanced network of security cameras at all times. Highly trained security guards are readily available to combat any threat. Other security measures are in place, too.
