Network Engineer

Responsibilities:

• Updating the entire WAN infrastructure and installing and configuring the network security monitoring software. This software greatly simplifies and streamlines the work of the System Administrators by allowing them to easily view what is happening in real time on the entire network with a few simple mouse clicks. Instead of administrators having to connect to each specific workstation to monitor network activity, the monitoring software automatically monitors and logs network activity. Some of the capabilities of this software are:
• Logging all keystrokes, the window they are typed in, with the time stamps of all user input activities.
• Monitor and log all emails sent and received by employees. All SMTP and POP3 messages are recorded for later viewing.
• Surveillance, monitoring, and logging of all internet sessions made on any PC on the network. This includes all FTP, HTTP, POP3, Chat Messenger, and any other TCP connections.
