Throughout this article, the following types of servers are grouped into a single category called application enumeration servers: Web Interface 2. In Version 1. To mitigate this risk: Always use HTTPS between the client and the application enumeration server to prevent an attacker from intercepting the ticket as it travels from server to client.

Reduce the ticket time-to-live as much as possible to reduce the amount of time an attacker would have to transfer the ticket from Machine A to Machine B.

A : During normal operation, a ticket must travel the following four segments of the network: From the STA to the application enumeration server From the application enumeration server to the client From the client to the Secure Gateway server From the gateway to the STA The first and last segments exist only between servers in your DMZ and the STA on your trusted network, meaning that an intruder would need to have access to your network to intercept the ticket along those lines.

To secure the second segment, put a certificate on your application enumeration Web server and allow clients to connect only if they use HTTPS. The third segment is always secured with SSL. To meet the requirements of the third bullet item, the CA root certificate needs to be installed on the Secure Gateway server and on the application enumeration server. Take care when installing the root certificate: You cannot simply double-click a root certificate file and run the certificate import wizard.

When asked which certificates to manage, select Computer account and then Local Computer. Browse to select your CA root certificate and complete the import wizard. Open Internet Services Manager. Right-click Default Web site and view the Properties. On the Web site tab, change the TCP port number from 80 to Click OK. The preceding change also affects any other resources you published from the STA Web server. The following is an example of how you would create a new Web site on port 81 for the STA.

View the properties of your new web site and change the TCP port to For Secure Gateway Version 1. Consider the following scenario: A user logs on to Web Interface and clicks the Outlook icon. The user connects through Secure Gateway and presents the ticket for admission. The gateway validates the ticket and allows the user to connect to a XenApp Server hosting Outlook. After working for a few minutes, the user returns to the application list on the Web Interface page and clicks the Excel icon.

Before connecting to a new server for Excel, the ICA Client first checks to see if any existing servers to which the client is already connected have the Excel published application available. The second ticket requested by Web Interface is never used because a second ICA session was not necessary. By default, the ticket times out after seconds. Logging is enabled in CtxSta.

For many years we have operated an incentive-based swimming skills scheme — the STA International Learn to Swim Programme ILSP and millions of children worldwide have learned to swim using this system.

As part of our commitment to improving the standards of swimming teaching and water safety worldwide we have, after consultation with our members and experts within the industry, developed ILSP, the comprehensive approach to teaching swimming. The ILSP recognises that pupils learn to swim at many different ages and progress at varying paces.

It also appreciates that swimming teachers use different techniques and have different levels of experience and that pool managers have diverse requirements.

But at the same time, both parties recognise that at no stage should safety, quality standards or consistency be compromised. The ILSP consists of five progressive schemes which are interlinked. There is a standalone scheme for people with disabilities, supporting awards for the more competent swimmer and diver and an introduction to the First Aid award. Home Travel Industry News.
