 Network
Security
We implement a number of security features to protect your Web site
and data including:-
Firewalls
A Firewall is a security system that acts as a protective
boundary between a network and the outside world by filtering
information coming from the Internet into our computer systems.
If an incoming packet of information is flagged by the filters
it is not allowed through. For example, we could instruct the firewall
to block any packet with the word "X-rated" in it. A
firewall can also implement security rules.
Without a firewall in place all of our computers
would be directly accessible to anyone on the Internet. A person
who knows what he or she is doing could probe and
access our computers. Virus Protection
Probably the most well-known threat is the computer virus. A
virus is a small program that can copy itself to other computers.
This
way it can spread quickly from one system to the next. Viruses
range from harmless messages to erasing all of your data.
Email virus scanners have been installed on each of our servers.
Virus scanners will scan all incoming and outgoing email, and will
inform
the recipient and sender of an infected message. Intrusion Detection (ID)
ID is the art of detecting
inappropriate, incorrect, or malicious activity by individuals
attempting to access and
manipulate information and
cause computer systems to be unreliable or unusable.
Sometimes, a distinction is made between misuse and intrusion detection.
The term intrusion is used to describe attacks from the outside.
Misuse is used to describe an internal attack. Port Scanner
Blockers
Hackers
may try to identify possible security problems in our operating
systems, and the applications running on
them, using
Port
Scanners. Port Scanner Blockers prevent hackers from identifying
and exploiting such weaknesses.
RAID1
RAID 1, also called Disk Mirroring, is installed on our servers
in case there is a disk crash. Basically we write all
of your data to two separate hard
disks
installed
on
the
server.
One
is
a mirror of the other. Should the primary
disk experience a hardware failure, the mirror disk will continue
operations as if nothing had happened. All of your data is protected.
We also have backups that can be restored if the RAID1 fails.
