Computer Virus
A computer virus is a computer program that can copy itself
and infect a computer without permission or knowledge of the
user. However, the term "virus" is commonly used,
albeit erroneously, to refer to many different types of malware
programs. The original virus may modify the copies, or the
copies may modify themselves, as occurs in a metamorphic virus.
A virus can only spread from one computer to another when
its host is taken to the uninfected computer, for instance
by a user sending it over a network or the Internet, or by
carrying it on a removable medium such as a floppy disk, CD,
or USB drive. Additionally, viruses can spread to other computers
by infecting files on a network file system or a file system
that is accessed by another computer. Viruses are sometimes
confused with computer worms and Trojan horses. A worm can
spread itself to other computers without needing to be transferred
as part of a host, and a Trojan horse is a file that appears
harmless until executed.

Firewall A firewall's basic task is to
regulate the flow of traffic between computer networks of
different trust levels. Typical examples are the Internet
which is a zone with no trust and an internal network which
is a zone of higher trust. A zone with an intermediate trust
level, situated between the Internet and a trusted internal
network, is often referred to as a "perimeter network"
or Demilitarized zone (DMZ).
A firewall's function within a network is similar to firewalls
with fire door in building construction. In former case, it
is used to prevent network intrusion to the private network.
In latter case, it is intended to contain and delay structural
fire from spreading to adjacent structures.
Without proper configuration, a firewall can often become
worthless. Standard security practices dictate a "default-deny"
firewall ruleset, in which the only network connections which
are allowed are the ones that have been explicitly allowed.
Unfortunately, such a configuration requires detailed understanding
of the network applications and endpoints required for the
organization's day-to-day operation. Many businesses lack
such understanding, and therefore implement a "default-allow"
ruleset, in which all traffic is allowed unless it has been
specifically blocked. This configuration makes inadvertent
network connections and system compromise much more likely.
IT IS CRITICAL for some you to have a firewall in place if
you are networked or connect to the internet. Without a properly
configured firewall your private data is exposed to the outside
world. Call SwiftTech today for an

Data Backups
In information technology, backup refers to making copies
of data so that these additional copies may be used to restore
the original after a data loss event. These additional copies
are typically called "backups." Backups are useful
primarily for two purposes. The first is to restore a computer
to an operational state following a disaster (called disaster
recovery). The second is to restore small numbers of files
after they have been accidentally deleted or corrupted. Backups
are typically that last line of defense against data loss,
and consequently the least granular and the least convenient
to use.
Since a backup system contains at least one copy of all data
worth saving, the data storage requirements are considerable.
Organizing this storage space and managing the backup process
is a complicated undertaking. A data repository model can
be used to provide structure to the storage. In the modern
era of computing there are many different types of data storage
devices that are useful for making backups. There are also
many different ways in which these devices can be arranged
to provide geographic redundancy, data security, and portability.

offers onsite, offsite, and online backup solutions. We can
recommend and setup a backup system and disaster recovery
plan or with an existing system. No matter what amount of
data or accessability we can get your data secured. Call us
