Protect Screens

RECOMMENDED PREVENTATIVE ACTION
Back up the NSA configuration file before you make
major configuration changes.
Use the Genie Backup Manager.
Use anti-virus software on your computer.
Create regular snapshots (recommended for volumes
with data that changes often).
Use anti-virus software on your computer to scan files
from others before saving them on the NSA.
You can also use anti-virus software on your computer
to scan the NSA for viruses.
Use RAID.
Back up data to another NSA or computer or an external
USB hard drive.
Place the NSA behind a hardware-based firewall. Ideally
the firewall should include deep packet inspection, IDP
(Intrusion Detection and Prevention), and anti-virus (like
ZyXEL's ZyWALL USG products for example).
Configure strong user passwords and Access Control
List (ACL) settings. See Chapter 8 on page 173
details.
Use HTTPS for Web Configurator access to the NSA
(see Section 11.4 on page 237).
Store sensitive data in encrypted NSA volumes (see
page Encrypted Volumes on page
9
for
126).
