Cisco eap fast is not installed, what should I do? Cisco program: what is it? Why do you need the Cisco Leap Module, Cisco Peap Module program? Network EAP or Open Authentication with EAP

“Cisco LEAP Module - what is this program?” — a request that identifies you as a person who actively uses network equipment. In this particular case, we mean Cisco products. Moreover, it is not necessarily iron. Maybe you just installed some of the software supplied by this particular company.

Cisco is a company whose clear specialization is network equipment. It was founded in 1984 by a married couple: Leonard Bosak and Sandra Lerner. It all started with the production of network routers. It’s impossible to call the company a pioneer in the industry. But it is worth noting that Cisco is the first company that was able to make a multi-user router commercially successful.

Serious changes overtook the company in 1990. Investors took the reins into their own hands, after which the company's founders left it. For this, Bosak and Lerner received $170 million. In their place came professional managers who were supposed to give a new impetus to the development of Cisco. Over time, the company's economic indicators really began to rise, and the spouses who founded it divorced.

Initially, the company was called Cisco (with a small letter). It was formed from an abbreviation of the name of the city of San Francisco. There is even a legend that initially the company was supposed to be called San-Francisco Systems, but due to some absurd accident during registration, the title page was torn, and the owners considered this a sign, so they decided to call the company simply Cisco, and with a small letter.

Of course, the company was later renamed Cisco Systems with a capital letter at the beginning. Now no one remembers the original name. As a logo, it was decided to choose the Golden Gate Bridge, for which the city, the birthplace of the Cisco company, is famous.

In addition to hardware, Cisco Systems is actively involved in software development, and one of its products is the Cisco leap module, which allows users to log in to access a Wi-Fi network.

So, in our article we tried to clearly talk about what kind of Cisco LEAP Module program this is, and about the company that gave it to the world.

Today we will look at:

When working on a computer running Windows, the user must always monitor what is happening on his computer. This operating system is considered the most popular in the world, so countless programs, viruses and tools have been developed for it to penetrate software onto your computer. In particular, today we will consider the situation when you noticed the Cisco LEAP Module program in the list of installed programs or processes on your computer.

If you saw unfamiliar software on your computer, then it could get onto your computer in three ways: you installed it yourself, but do not remember it, another PC user did it for you, or during the installation of the program the checkboxes that answer were not unchecked in time for installing additional software.

Naturally, having noticed the Cisco LEAP Module program on your computer, two questions arise: what kind of program is it, and also whether it is a virus.

A little about Cisco

Cisco is a fairly well-known American company that develops and sells network equipment. In our country, users rarely know about this company, but abroad, almost any American company or home has a Cisco router and other network equipment and software.

What is the Cisco LEAP Module program?

Actually, the Cisco LEAP Module program is only part of a software package that is aimed at setting up authentication protocols in Cisco Wi-Fi networks.

If we talk specifically about Cisco LEAP Module, the program stands for Lightweight Extensible Authentication Protocol and is a module of a lightweight extensible authentication protocol.

Is this program necessary?

No, unless you are a user of Cisco network equipment.

What is the best way to remove a program from your computer?

This tool must be uninstalled from the computer along with other Cisco programs. You can carry out this operation in the standard way through the “Control Panel” menu, but it will be better if you use the Revo Uninstaller program for uninstallation, which is aimed at completely removing programs from the computer.

Removing Cisco LEAP Module via Control Panel

Uninstalling Cisco LEAP Module Using Revo Uninstaller

We recommend uninstalling programs using Revo Uninsaller for the simple reason that, in addition to standard uninstallation, the program will additionally scan the system for remaining files, folders and registry entries. This tool will allow you to remove programs from your computer as efficiently as possible, eliminating the possible occurrence of conflicts and increasing system performance.

If necessary, download Revo Uninstaller from this link and then install your computer. Launch the program. As soon as the list of installed software is displayed on the screen, find the Cisco LEAP Module program, right-click on it and select “Uninstall”. Complete the uninstallation procedure following the system instructions. At the scanning stage, we recommend selecting the “Full” option, since this is the only way the program can most thoroughly scan the system.

Check the list for availability and . They will need to be removed using the same principle.
Restart your computer for the system to finally accept the changes.

That's all on the topic.

A company that produces network equipment such as communicators, routers, screens, modems, routers, servers and much more. It is also a major manufacturer and leader in computer and networking technologies.

Cisco

This is an American company that develops and sells network equipment. The main motto of the company is to provide the opportunity to purchase all network equipment only from Cisco Systems.

In addition to manufacturing equipment, the company is the world's largest high-tech enterprise. You also ask: “Cisco - what is it?” At the beginning of its activities, the company produced only routers. Now it is the largest leader in the development of technologies for the Internet. Created a multidisciplinary certification system for network specialists. Cisco professional certifications are very valuable, at the expert level (CCIE) and are highly respected in the computer world.

The name Cisco itself comes from the city of San Francisco in California. The logo is a replica of the Golden Gate Bridge. The company has existed in Russia, Ukraine and Kazakhstan since 1995. In 2007, greatly increased sales volume in the information security field amounted to approximately $80 million. And since 2009, there has been a research and development center in Russia.

This company is at the forefront of building extensive and very reliable indoor networks. The Aironet series uses security, high-precision controllability, and security when building a Wi-Fi network. This series has five access points, as a result, it helps in solving many problems. Such a network supports three standards: a, b, g, as well as 802.11n, so that it can increase as much as possible

You can change rights, add and remove users in a network of two or three access points manually. But if it’s more, then you need to use a device such as a controller. This intelligent mechanism not only monitors the operation of the network, but also, by analyzing the operation of access points, distributes the load equally among the access points in the network. There are two controller models: 2100 and 4400.

Cisco Academy Program

In the context of a progressive technology economy, knowledge in the field of networks and the Internet is provided by the network program of the Cisco Academy.

Of course, you want to know: Cisco - what is it? It includes materials from the Internet, practical exercises, and assessment of students' knowledge. This program was founded in 1997 in 64 educational institutions. And it has spread to 150 countries. Program specialists prepare future teachers at Training Centers (SATS). Then the teachers teach regional teachers, and they teach local ones, and the locals teach the acquired knowledge to students. Upon completion of training, students receive certificates “Network Specialist” (CCNA) and “Network Professional” (CCNP). At this time, in addition to these certificates, cadets can also take courses in various areas. Over time, the program continually adapts to high standards.

Cisco Unified Computing System (UCS)

Currently, business requires a quick response, so people are increasingly paying attention to the Cisco Unified Computing System (UCS). So, Cisco - what is it?

The world's first platform where you can create data processing centers. It provides an intelligent, programmable infrastructure that simplifies and accelerates the right class of applications and services on the cloud you need. The system unifies model-based management, allocates appropriate resources, and supports migration to make applications faster and easier to deploy. And all this thereby increases the level of reliability and safety. What does this platform ultimately do:

combines different network resources and Cisco servers into one system;
increases application availability and performance;
minimizes services for operational work;
Optimally distributes data center capabilities to reduce cost of ownership.

Record-breaking application performance is achieved using the Cisco Unified Computing System.

Cisco Eap

Everyone wants to know: Cisco Eap - what is it? Let's say it's an advanced authentication protocol. Wireless packets of information are translated into packets that are transmitted over wires and sent to the authentication server and back. If necessary, such a system is used with a passive role as an access point. There are EAP methods:

LEAP;
EAP (PEAP)-MS-(CHAP) version 2;
PEAP Generic Token (GTC);
EAP over Secure Tunnel (FAST);
EAP tunnel of carelessness (TLS);
EAP-Tunneled TLS (TTLS).

EAP runs under iOS. He especially feels verbal attacks, not new types of attacks. You just need to develop a strong password and change it periodically. Now let's look at Cisco Eap Fast - what is it?

EAP-FAST is a program developed by Cisco Systems. An EAP method such as Leap has proven itself well among IP phones and is supported by FreeRADIUS. Ask: Cisco Leap Module - a program for authorizing Wi-Fi users. Vulnerable when calculating lists of MD5 password bundles.

Cisco Peap Module

We are interested in: Cisco Peap Module - what is it? A very simple, at first glance, program for timely cleaning Windows from various outdated and unnecessary registries. This cleaning improves system performance. Supported by different OS like Windows Vista/7/8/Server 2012.

This article provides an example configuration for EAP (Extensible Authentication Protocol) authentication of wireless users against a local RADIUS server database on an access point running Cisco IOS®.

Due to the passive role that the access point plays in EAP (it converts wireless client packets into wired packets and forwards them to the authentication server, and vice versa), this configuration is used with almost all EAP methods. These methods include (but are not limited to) LEAP, Protected EAP (PEAP)-MS Mutual Authentication Protocol (CHAP) version 2, PEAP Generic Token Card (GTC), EAP Flexible Authentication over Secure Tunnel (FAST), EAP Security Protocol transport layer (TLS) and EAP-Tunneled TLS (TTLS). You must configure the authentication server appropriately for each EAP method. This article contains only information on setting up an access point.

Requirements

When setting up, you may need the following knowledge:

Understanding the Cisco IOS GUI or CLI.
Understanding the concept of EAP authentication.

Components used

Cisco Aironet access point running Cisco IOS.
Virtual LAN (VLAN), let's assume that there is only one of it in the network.
RADIUS authentication server that successfully integrates into the user database.

Cisco LEAP and EAP-FAST support the following authentication servers:

Cisco Secure Access Control Server (ACS)
Cisco Access Recorder (CAR)
Funk Steel Belted RADIUS
Interlink Merit

Microsoft PEAP-MS-CHAP version 2 and PEAP-GTC support the following authentication servers:

Microsoft Internet Authentication Service (IAS)
Cisco Secure ACS
Funk Steel Belted RADIUS
Interlink Merit
Authorization can be performed by any other Microsoft authentication servers.

Note:

It is necessary to consult with the manufacturer of the equipment installed at the client to clarify under what conditions authentication servers using the EAP-TLS, EAP-TTLS and other EAP methods are supported by their products.

The information presented in this document was obtained on testing equipment under specially designed laboratory conditions. Only data obtained from devices with default configuration was used in writing this document. In a production network, you need to understand the consequences of executing all commands.

Settings

This configuration involves setting up EAP authentication on an access point running IOS.

Like most password-based authentication algorithms, Cisco LEAP is sensitive to dictionary attacks. This is not a new type of attack or a new Cisco LEAP vulnerability. To mitigate dictionary attacks, it is necessary to develop a strong password policy. This includes using strong passwords and changing them periodically.

Network EAP or Open Authentication with EAP

With any authentication method based on EAP/802.1x, you may wonder what the differences are between network EAP and open authentication with EAP. This applies to the values in the Authentication Algorithm field in the management and binding packet headers. Most wireless client device manufacturers set this field to 0 (open authentication) and then indicate whether they want to perform EAP authentication later during the association process. In Cisco products, this value is set differently, namely from the beginning of the association with the EAP network protocol flag.

If the network has clients that are:

Cisco customers - must use network EAP.
Third party clients (including CCX compliant products) must use open authentication with EAP.
A combination of Cisco and third-party client devices—you must select both network EAP and open authentication with EAP.

Defining the Authentication Server

The first step in configuring EAP is to identify and communicate with the authentication server.

1. On the Server Manager access point tab (menu item Security > Server Manager), you must perform the following steps:

Enter the IP address of the authentication server in the Server field.
Specify the shared secret key and ports.
Click Apply in order to create a definition and populate the drop-down lists.
Set the server IP address in the Default Server Priorities > EAP Authentication type > Priority 1 field.
Click Apply.

AP# configure terminal

AP(config)# aaa group server radius rad_eap

AP(config-sg-radius)# server 10.0.0.3 auth-port 1645 acct-port 1646

AP(config-sg-radius)# exit

AP(config)# aaa new-model

AP(config)# aaa authentication login eap_methods group rad_eap

AP(config)# radius-server host 10.0.0.3 auth-port 1645
acct-port 1646 key labap1200ip102

AP(config)# end

AP# write memory

2. The access point must be configured on the authentication server as an AAA client.

For example, on a Cisco Secure Access Control Server, this is configured on the Network Configuration page, which defines the access point name, IP address, shared secret password, and authentication method (RADIUS Cisco Aironet or RADIUS Cisco IOS/PIX). For information on authentication servers that are not classified as access control servers, refer to their manufacturer's documentation.

You must ensure that the authentication server is configured to use the desired EAP authentication method. For example, for a Cisco Secure Access Control Server that uses LEAP, you must configure LEAP authentication on the System Configuration - Global Authentication Setup page. Click System Configuration, then press Global Authentication Setup. For information on non-access control authentication servers or other EAP methods, consult the manufacturer's documentation.

The following figure shows how Cisco Secure ACS is configured to use PEAP, EAP-FAST, EAP-TLS, LEAP, and EAP-MD5.

Defining client authentication methods

Once the access point determines where to send the client authentication request, it must be configured to use the following methods.

Note: These instructions are for WEP-based installations.

1. On the Encryption Manager access point tab (menu item Security > Encryption Manager) you must perform the following steps:

Specify usage WEP encryption.
Indicate that the use of WEP is mandatory Mandatory.
Make sure the key size is set to 128-bits.
Click Apply.

You can also run the following commands from the CLI:

AP# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

AP(config)# interface dot11radio 0

AP(config-if)# encryption mode wep mandatory

AP(config-if)# end

AP# write memory

2. Perform the following actions on the SSID Manager access point tab (menu item Security > SSID Manager):

Select the desired SSID.
In the "Authentication Methods Accepted," checkbox Open and using the drop-down list select With EAP.
Check box Network-EAP if you have a Cisco client card.
Click Apply.

You can also run the following commands from the CLI:

AP# configure terminal

Enter configuration commands, one per line. End with CNTL/Z.

AP(config)# interface dot11radio 0

AP(config-if)# ssid ssid labap1200

AP(config-if-ssid)# authentication open eap eap_methods

AP(config-if-ssid)# authentication network-eap eap_methods

AP(config-if-ssid)# end

AP# write memory

Once the core functionality has been confirmed to work correctly with the basic EAP setup, additional functionality and key management can be added. Place more complex functions on top of the functional base to make troubleshooting easier.

Examination

This section contains information that can be used to verify that the configuration is working.

Some commands show supported by the tool Output Interpreter Tool(only for registered users), which allows you to view an analysis of the command output show.
show radius server-group all– Lists all configured RADIUS server groups on the access point.

Troubleshooting

Troubleshooting Procedure

To troubleshoot your configuration, you must follow these steps:

A new profile or connection must be created in the client-side utility or software with the same or similar parameters to ensure that nothing has been corrupted in the client settings.
To ensure that RF interference does not interfere with successful authentication, you must temporarily disable authentication using the steps below:
Execute commands from the CLI no authentication open eap eap_methods, no authentication network-eap eap_methods and authentication open.
From the GUI on the SSID Manager page you need to uncheck Network-EAP, check the box Open and set the dropdown list back to No Addition.

You must ensure that shared secret passwords are synchronized between the access point and the authentication server.
From the CLI, select the line radius-server host x.x.x.x auth-port x acct-port x key .
From the GUI on the Server Manager page, re-enter the shared secret key for the corresponding server in the "Shared Secret" field.

Remove all user groups from the RADIUS server. Sometimes there may be conflicts between the user groups defined by the RADIUS server and the user groups on the underlying domain. Check the RADIUS server log entries for failed attempts and the reasons why those attempts failed.

Troubleshooting Commands

Some commands show supported by the tool Output Interpreter Tool(only for registered users), which allows you to view the results of the command show.

Chapter Debugging Authentication contains a significant amount of detail on how the output of EAP-related debugging commands can be collected and interpreted.

Note: Before you run commands debug, you need to read the section Important information about debugging commands.

debug dot11 aaa authenticator state-machine– Outputs the main sections (or states) of the negotiation between the client and the authentication server.
Note: In Cisco IOS software releases prior to 12.2(15)JA, the command syntax is debug is as follows debug dot11 aaa dot1x state-machine.
debug dot11 aaa authenticator process– Displays single records of negotiation dialogues between the client and the authentication server.
Note: In Cisco IOS software releases prior to 12.2(15)JA, the debug command syntax is as follows: debug dot11 aaa dot1x process.
debug radius authentication– Outputs RADIUS negotiations between the server and client bridged to the access point.
debug aaa authentication– Outputs AAA negotiations for authentication between the client device and the authentication server.
