SecureWALL comprises of several independent
systems working together in unison. Each system is based on
Best-of-Breed technology and plays an essential role
in enforcing one or more aspects of the acceptable Use and anti-virus
policies. |

With
its unique Dual-Firewall and Intrusion Detection System (IDS) combination,
SecureWALL delivers 360 degree perimeter security, to check and
intercept covert attempts to access the system from outside the
organisation or from within!. Any attempt to scan or penetrate
the SecureWALL, will raise an immediate alarm and in the event
of an malicious attack, it can instigate counter measures to neutralise
the attack. |

A
mine of invaluable information and resources it may be, but the
web is also a source of undesirable material from a business
liability perspective. SecureWALL takes each user's request
for information and checks whether the destination requested or
the resulting web page contains suitable material for the user
to receive. If not, it immediately blocks the source of the material
and informs the user that it is not allowed. This ensures a more responsible
and productive Internet use by employees. |

No
one could envisage life without email. But how much time do we
spend each day trolling through junk (spam) email distractions.
Clearing user mail boxes of offensive, bandwidth consuming spam
and other non-work related mail, will free up valuable time for
the real work at hand. SecureWALL will ensure email sent or received,
will be free from viruses and attach a legal
disclaimer footer to all outgoing mail. The content of all
incoming and outgoing email and attachments will also be screened
for offensive remarks, jokes etc. An email filtering system may
also be used to ensure confidential information cannot be mailed
out of the organisation without the proper approval. |

As
part of it's role, SecureWALL acts as a gateway for all incoming
and outgoing Internet traffic and email. As this information passes
through SecureWALL, it is vigorously screened for viruses, worms
and Trojans, so you never receive, or inadvertently send, your
customers a potentially harmful virus. |

As well as providing anti-virus protection for all internet
traffic entering or leaving your network, you should also protect
your network servers and workstations. Network Administrators
need to lock-down client PCs
so users cannot alter or disable their
anti-virus software.
SecureWALL provides an optional * Desktop Anti-Virus Management System
that will deploy and install the anti-virus software on to each
individual PC, without any end user interaction. Regular updates
to the anti-virus software are also discreetly pushed onto each
PC, again without any user involvement

Every
company has a one or more individuals who believe that restrictions
or company rules do not apply to them.
It has been known for such misguided individuals to try and circumvent
company restrictions using commonly available hacking
and scanning utilities. Such tools cause harm and disruption
to internal servers and systems. SecureWALL employs the same Firewall
and Intrusion Detection technology as used on the Internet, to protect
and monitor activity on your internal private network. Once detected,
details of an offending PC or user, are sent to the system administrator.

Even
with proper policing there will be times when legitimate users
can inadvertently abuse their privileges, such as a user sending
or receiving large attachments who may ‘hog the highway’ for
all other users and reduce Internet traffic to a crawl. Occasional
checks on Internet usage will help ensure no one monopolises the
facility unduly. Therfore in conjunction with our manged service
an Activity Report is sent directly to the systems administrator,
detailing who been going where for what
and when. |

SecureWALL uses a dedicated monitoring system to keep a constant
check on the status of its core systems, and other essential
services such as email, web hosting and communication links.
Should a core system or monitored service shut down unexpectedly,
SecureWALL’s internal monitoring system would automatically
detect and restart it, alerting the Administrator as necessary.

For
many users, Internet access and email is provided as a perk of
the job, so long as it is not abused and does not interfere with
their work. Deciding who can
access the Internet, when they
can access it and where they
are allowed to go is controlled by SecureWALL's User Management
System. For example, you may decide that by default every network
user should be given access for browsing purposes but not for chat
rooms, instant messaging, streaming video, mp3 sites or newsgroups.
decide that everyone can have a 'courtesy' browse between 12 and
1 over lunch but only selected individuals will get full daily
access.

Many
(perhaps the majority) of companies who have encountered security
issues, have so from the 'inside'. Although this may seem unlikely
at first, it is actually the most common reported abuse. With
the focus clearly on external security and intrusion detection
via the front door, the back door can often be left unlocked
and unchecked!
As you read this paragraph, there may well be several PCs, Laptops
etc on your network that currently holding sensitive information,
such as salary structures, redundancy shortlists, confidential
documents etc, which could be exposed to the rest of the network
via a Windows drive or directory 'share', possibly even a undetected
Trojan Horse infection.

Could you honestly say all your employees would be 100% loyal and
trustworthy when faced with rumours of redundancies, 'down-sizing',
lower
than expected pay rises, overlooked for promotion, or perhaps a new
job with
new loyalties!. It doesn't take much to go from being loyal to untrustworthy
and suddenly you may have an possible 'enemy within' looking to steal
confidential customer or company information.
SecureWALL's optional 360° Vulnerability
Monitoring System can perform
a
full Security Scan of every Server, PC, MAC and Laptop on the network
and
produce a detailed report on what vulnerabilities exist and what
should be
done to correct them i.e. drive and directory shares, backdoors,
weak
passwords and other 'holes' etc.
As part of the Managed Service, an optional Quarterly Vulnerability
Assessment can be performed on your internal network and on external facing
systems to ensure your security remains effective and is shown to be
so.
This may be particularly important for reassuring customers or as part
of a
BS-7799 compliance procedure.
