Defining A Firewall
A Firewall is designed to prevent unauthorized access to
a computer or network connected to the Internet. It is a system
or a combination of systems that enforces a virtual boundary
between two or more networks.
Typically, firewall software works by 'hiding' your computer
from unknown users, via ports connecting to the Internet.
Firewall software provides stealth capability to your computer
on the network, hiding it from hackers who scour the Internet
looking for vulnerable computers that they can gain access
to.
Packet Filtering - Packets (small chunks of data)
are analyzed against a set of filters. Packets that make it
through the filters are sent to the requesting system and
all others are discarded.
Proxy Service - Information from the Internet is retrieved
by the firewall and then sent to the requesting system and
vice versa.
Stateful Inspection - A newer method that doesn't
examine the contents of each packet but instead compares certain
key parts of the packet to a database of trusted information.
Information traveling from inside the firewall to the outside
is monitored for specific characteristics, then the incoming
information is compared to these characteristics. If the comparison
yields a reasonable match, the information is allowed through.
Otherwise it is discarded.

eConceal Firewall
eConceal Firewall is a comprehensive software firewall developed
to prevent unauthorized access to a computer or network that
is connected to the Internet. It enforces a boundary between
two or more networks by implementing default or user-defined
access-control policies (rules) between two or more networks.
Your system becomes vulnerable to unauthorized access when
you connect to a public network like the Internet. eConceal
is designed to protect you from unauthorized access by people
designed to disrupt or destroy your personal and/or business
data functions, often stealing valuable information like your
Identity, account numbers, other personal information, confidential
information or proprietary business related data among other
things.
How eConceal Works?
eConceal works by allowing or blocking different kinds of
Internet access based on default and user created rules. These
rules function as filters by analyzing data packets to see
if they fulfill the filter criteria and then allow or block
the access accordingly.
eConceal firewall provides a set of pre-defined rules that
a user can choose from. Rules that are appropriate to the
security needs of the organization can be chosen and added
to the system. Some the pre-set rules are: ARP, DHCP &
BOOTP, DNS, E-mail, WWW, News, NetBios, FTP, ICMP, ICQ, Telnet
& SSH, IRC, MSN, and VPN. These Rules are based on various
applications and protocols involved in Internet access, in
one form or the other.
Features
- NetWork Data Filtering - Continuously monitors
and filters network IP and Non-IP Traffic.
- Filtering Level - Supports Application and Packet
Level filtering. Application Level helps you set up rules
for a particular Application. Packet Level provides filtering
for incoming and outgoing data packets
- User-defined Rules - Provides a powerful traffic
filtering system with user-defined processing rules. Users
can define rules according to their requirements and implement
customized traffic filtering.
- Preset Rules - Offers a set of pre-defined rules
users can choose from, in order to enforce access control.
The different types of rules are ARP, DHCP & BOOTP,
DNS, E-mail, WWW, News, Net Bios, FTP, ICMP, ICQ, Telnet
& SSH, IRC, MSN, and VPN.
- Network Traffic Monitor - Shows current data traffic
on your system, including information regarding open programs
and ports used in communication.
- Port Monitoring - All communication between your
system and the outside world take place through ports. A
port is 'virtual slot' in your TCP along with a UDP stack.
A UDP stack is used to map a connection between two hosts,
and also between the TCP/UDP layer and the actual applications
running on the hosts. eConceal prevents scanning of these
ports and alerts you of any such attempts from unauthorized
users and attackers.
- Stealth Mode - Surf the Internet invisibly, without
letting other online users see you. When online, your computer
constantly receives and responds to information requests
from other computers. In stealth mode your computer will
not respond to this flow of queries and requests.
- Webpage Scanning - Provides Parental Control by
blocking offensive and pornographic websites. Enterprises
can stop non-business websites in office, to prevent wastage
of Bandwidth and accelerate productivity.
- Pop-Up Blocking - Stops all kinds of Pop-ups to
save bandwidth and system resources. Option is available
for Whitelisting specific websites.
- Multiple Network Adapter Support - Supports configuration
of multiple network adapters.
- Comprehensive Logs - Stores log information detailing
programs involved in outgoing/incoming traffic, Communication
Protocols used, Source and Destination IP addresses, direction
of traffic, and action taken depending on rules in force.
In addition, it maintains an Event Log detailing user events
- e.g. changing security levels, loading rules, firewall
shutdown etc .
- Real-time Traffic Monitoring Reports - It provides
clear, concise graphical and non-graphical reporting on
internal and external traffic. Various reports based on
Application, Expert Rule, Zone Rule, IP and Date are available
along with graphs of different styles like Bar, Pie, Line
and alike .
- Password-protection - Ensures security by implementing
password protection for the Firewall in order to prevent
unauthorized access to its settings.
- Easy Installation and Configuration - eConceal
is easy to install and configure. It does not affect Windows
system files and does not require any additional libraries
(DLLs).
