NokiaIPSOOverview·Chapter2 49 Using HTTP/HTTPS The Nokia Network Voyager configuration interface is enabled by default on all IPSO releases and is configured to be accessible over standard HTTP on TCP port 80. Nokia uses the open-source Apache HTTP Server to run the Nokia Network Voyager Web user inter- face. It is possible (and highly recommended) to reconfigure Voyager to be only accessible using HTTPS, and you can also manually change the port number that Apache listens on. These configuration options are thoroughly covered in Chapter 4. W arNiNg Because IPSO uses third-party software for SSH and HTTP/HTTPS servers, you need to be aware that Nokia may not be as quick to adopt security fixes as the vendors of these software packages. It is a good idea to subscribe to the mailing lists provided by the OpenSSH and Apache projects to remain informed of any potential software vulnerabilities. Gaining Console Access
