It is designed to monitor all incoming and outgoing network traffic and protect your computer from all types of network based attacks. eScan includes a set of predefined access control rules that you can remove or customize as per your requirements. These rules enforce a boundary between your computer and the network. Therefore, the Firewall feature first checks the rules, analyzes network packets, and filters them on the basis of the specified rules. | + | <p class=MsoNormal align=center style='margin-top:12.0pt;margin-right:0in; |

- | By default, the firewall operates in the '''Allow All''' mode. However, you can customize the firewall by using options like '''Limited Filter''' for filtering only incoming traffic and '''Interactive Filter '''to turn off and block all. The eScan Firewall also allows you to specify different set of rules for allowing or blocking incoming or outgoing traffic. These rules include Zone Rules, Expert Rules, Trusted Media Access Control (MAC) Address, and Local IP list. | + | |
- | This page provides you with options for configuring the module. You can configure the following settings to be deployed to the eScan client systems. | + | |

Firewall module is designed to monitor all incoming and outgoing network traffic and protect your computer from all types of network based attacks. eScan includes a set of predefined access control rules that you can remove or customize as per your requirements. These rules enforce a boundary between your computer and the network. Therefore, the Firewall feature first checks the rules, analyzes network packets, and filters them on the basis of the specified rules. When you connect to the Internet, you expose your computer to various security threats.
<img border=0 width=578 height=350 id="Picture 107" src="eScan_Corporate360_UserGuide_revised_files/image171.jpg">
The Firewall feature of eScan protects your data when you:
• Connect to Internet Relay Chat (IRC) servers and join other people on the numerous channels on the IRC network.
• Use Telnet to connect to a server on the Internet and then execute the commands on the server.
• Use FTP to transfer files from a remote server to your computer.
• Use Network Basic Input Output System (NetBIOS) to communicate with other users on the LAN connected to the Internet.
• Use a computer that is a part of a Virtual Private Network (VPN).
• Use a computer to browse the Internet.
• Use a computer to send or receive email.
By default, the firewall operates in the Allow All mode. However, you can customize the firewall by using options like Limited Filter for filtering only incoming traffic and Interactive Filter to monitor incoming and outgoing traffic. The eScan Firewall also lets you specify different set of rules for allowing or blocking incoming or outgoing traffic. These rules include Zone Rules, Expert Rules, Trusted Media Access Control (MAC) Address, and Local IP list. This page provides you with options for configuring the module. You can configure the following settings to be deployed to the eScan client systems.
Allow All – Clicking Allow All disables the eScan Firewall i.e. all the incoming and outgoing network traffic will not be monitored/filtered.
Limited Filter – Clicking Limited Filter enables eScan Firewall in limited mode which will monitor all incoming traffic only and will be allowed or blocked as per the conditions or rules defined in the Firewall.
Interactive - Clicking Interactive enables eScan Firewall to monitor all the incoming and outgoing network traffic and will be allowed or blocked as per the conditions or rules defined in the Firewall.
Following tabs are available:
Zone Rule
Expert Rule
Trusted MAC Address
Local IP List
Application Rule
Zone Rule
This is a set of network access rules to make the decision of allowing/blocking of the access to the system. This will contain the source IP address or source Host name or IP range either to be allowed or blocked.
Buttons (to configure a zone rule)
Add Host Name – This option lets you add a "host" in the zone rule. After clicking Add Host Name, enter the HOST name of the system, select the zone (Trusted/Blocked) and enter a name for the zone rule. Click OK to create the zone rule.
Add IP – This option lets you add an IP address of a system to be added in the zone rule. After clicking Add IP, enter the IP address of the system, select the zone (Trusted/Blocked) and enter a name for the zone rule. Click OK to create the Zone Rule.
