Internet Security And Malware Protection - L3Harris Narda SignalShark User Manual

Internet security and malware protection

A high standard of safety and security is a given at Narda Safety Test Solutions GmbH. This
naturally also applies to IT security.
The SignalShark is based on an X86 processor architecture running the Windows 10
operating system. The device can be compared to a portable PC, and it supports an Internet
connection as well as the use of external storage media.
As with any PC, we also recommend that you perform a regular virus scan when using the
SignalShark to protect it from malware. At the very least, you should perform a virus scan if
any of the following applies:
• The SignalShark was connected to an "unsafe" network, such as the Internet.
• The SignalShark was connected to an external storage medium such as an SD card or a
USB memory card.
• The SignalShark was made available to other people as a demo unit or as an exhibit at a
trade fair, for example.
Depending on the anti-virus software used, a virus scan can load the system quite heavily,
which is why Windows Defender is deactivated ex-works to ensure maximum real time
performance when making measurements.
There are several ways of performing a virus scan:
• Temporary activation of Windows Defender: See Activating windows defender below.
• Installation of antivirus software: The software should be set to on demand scan when
making measurements to avoid impairing measurement performance.
• Scanning from a USB stick: Some software manufacturers provide antivirus solutions
that can be installed on a USB stick and executed from there. If this is done, please note
that the SignalShark uses a UEFI boot loader.
Please observe the following points:
Before connecting instruments to your company's network, consult your organization's IT-
department or system administrator to ensure compliance with your company policies.
Make sure you update the antivirus program to the latest virus definitions before running a
scan.
Perform an antivirus scan regularly.
Do not connect SignalShark to an unsafe network (e.g. the Internet) without first activating
antivirus protection and the firewall.
Please take care to observe the manufacturer's conditions of use when using antivirus
software.
