Network Anti-Virus Protection
Feature
|
 By their nature,
anti-virus products typically require regular, active maintenance on every PC.
When a new virus is discovered, all anti-virus software deployed within an
organization must be updated with the latest virus definition files; failure
to do so severely limits the effectiveness of anti-virus software and disrupts
productive work time. With more than 50,000 known viruses and new virus
outbreaks occurring regularly, the task of maintaining and updating virus
protection can become unwieldy. Unfortunately, many small to medium businesses
don�t have adequate IT staff to maintain their anti-virus software. The
resulting gaps in virus defenses may lead to data loss and decreased employee
productivity.
The widespread outbreaks of viruses, such as "ILOVEYOU" and
Melissa, illustrate the problematic nature of virus defense for small and
medium businesses. Users without the most current virus definition files allow
these viruses to multiply and infect many other users and networks. SonicWALL
Network Anti-Virus prevents occurrences like these and offers a new approach
to virus protection. SonicWALL�s family of
firewall appliances constantly monitors the
version of the virus definition file and automatically triggers download and
installation of new virus definition files to each user�s computer. In
addition, the SonicWALL restricts each user�s access to the Internet until
they are protected, in essence acting as an enforcer of the company�s virus
protection policy. This new approach ensures the most current version of the
virus definition file is installed and active on each PC on the network,
preventing a rogue user from disabling the virus protection and potentially
exposing the entire organization to an outbreak.
Network Anti-Virus Features and Benefits
Network Wide 24x7 Virus Protection.
Based on Network Associates' McAfee VirusScan
technology, SonicWALL Network Anti-Virus automatically and transparently
updates the virus software on every computer on the network, providing
around-the-clock protection from new viruses as soon as the cure is
available.
Enforcement of Virus Policy on All Windows PCs.
Virus protection is enforced for any Windows
computers on the LAN. If a user removes or deactivates the virus protection
software on their computer, it is automatically reinstalled or reactivated
the next time they try to access the Internet.
E-mail Attachment Filtering.
Enables custom rule configuration for filtering
potential virus carrying E-mail attachments. The network administrators can
either delete or disable E-mail attachments based on a centralized list of
file extensions.
E-mail Attachment Filtering Alert Service
E-mail Attachment Filtering Alert Service provides attachment
blocking on inbound SMTP and POP3 e-mail protocols. For example, this
feature can provide Anti-Virus protection for e-mail received via Yahoo or
Hotmail accounts. Additionally, when this service is selected, the SonicWALL
automatically blocks virus-specific attachments during rapid outbreaks, even
before Anti-Virus signature (DAT) files are available.
Reduced Administrative Costs.
Save time and money in installation and
maintenance. It's no longer necessary to manually update anti-virus software
for every computer on your network, allowing your valuable IT resources to
focus on other issues.
Protection Against Viruses from All Sources.
Unlike other anti-virus products that scan files
only at the gateway, SonicWALL Network Anti-Virus provides protection at
both the gateway and the desktop. This method detects and cleans viruses
from all sources including any vulnerable back doors.
Trojan Horse Protection.
"Trojan horse"
viruses appear to be benign files often sent as E-mail attachments, but in
reality are malicious viruses. These Trojans can be used to open a path into
the LAN for the sender, or even take over computers on the network to be
used in attacks on other remote networks. SonicWALL Network Anti-Virus
detects and deletes these Trojans before they can take control of your
network.
Comprehensive Virus Alerting and Logging.
With SonicWALL Network Anti-Virus, the
administrator is kept abreast of newly discovered serious viruses. In the
case of a widespread infection, policies can be put in place to
automatically update anti-virus software to a version with the fix before
the network is infected. When virus alerts are issued, the information is
logged in the SonicWALL Internet security appliance and an E-mail alert is
sent to the administrator with detailed information on the virus.
