IT Security: Network Troubleshooting

Six proven steps to figuring out what’s wrong with your IT infrastructure

Step Six: In the event that your basic and moderate IT troubleshooting efforts do not prove successful, there may be a need to deploy advanced technical tools such as port scanners, sniffers and network traffic management devices. Many of these devices may require advanced support from industry professionals, and may include placing a support call to a third-party provider. One of the major differences that you will see from vendors that provide advanced network diagnostics are that they quite often will be highly trained experts, who can provide secure remote connectivity (if your company permits), and perform diagnostics directly on your system.
