Role : Development
Description: Since the number of public IP's is limited, we use NAT to provide internet to all the
corporate network machines. We use of restricted cone and dense NAT implementation to support more
than 64k connection for NAT-IP. When restricted cone NAT is not possible we do Port Translation to
make the connection possible.
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing
* Bugs fixing and testing
3) Application layer Gateways(ALGS) for IPv4 in SMP Environment
Product : iGateway Software
Role : Development
Description: Applications like File Transfer Protocol (FTP), Session Initiation Protocol (SIP),
Trivial File Transfer Protocol (TFTP), Real Time streaming Protocol (RTSP) etc., uses two different
connections namely Control connections and Data connection. These applications will exchange
dynamically which port they will be using for data connection in the control packets ALGS will
process those packets and create holes in the firewall in order to allow data connections. If in
Control packets internal IP's are exchanged the packets are modified with the NAT-IP's. Application
level attack checks are done and generate log messages accordingly.
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing
* Bugs fixing and testing
4) Proxy Transport (Pseudo Transport layer) in SMP Environment
Product : iGateway Software
Role : Development
Description: It is an intermediate layer which acts as the mediator between Firewall and ALGS. ALG
require the full packet for processing, when packets are coming in fragments Proxy transport will
take care of buffering the packets and deliver the packets to ALG accordingly. Proxy Transport also
maintains timers to retransmit the packets which are not delivered
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing
* Bugs fixing and testing
5) Pinhole Module in SMP Environment
Product : iGateway Software
Role : Development
Description: Pinhole is a type of associations in which some of the five tuple information's are
unknown. This is used by ALGS when ever it wants to create pinholes in Firewall to allow data
connections to go through the box.
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing ,Bugs fixing and testing
6) Port Trigger Feature
Product : iGateway Software
Role : Development
Description: Some applications divides the connections in two half's one is control and other is
data. In these applications administrator knows before hand which port and protocol is used for
control and which port and protocol is used for data. So Administrator is required to create two
different filters to allow control and data. In this case administrator need to create a port
trigger record instead of two filters, which make use of pinhole module and create pinhole in the
firewall for the data connection once the control connection is initiated
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing
* Bugs fixing and testing
7) NATPT(Network address translation and Protocol translation)
Product : iGateway Software
Role : Development
Description: When ever IPv6 Machine want to communicate with IPv4 Machine, administrator is required
to configure the NATPT record and a prefix.When packet come to Firewall NATPT will convert the IPv6
address to the corresponding IPv4 address and send the packet out and do vice versa.
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing
* Bugs fixing and testing
8)Firewall IPv6 in SMP environment
Product : iGateway Software
Role : Development
Description: After receiving the packets from net filters, Firewall applies required actions
according to the filter records that are configured in the firewall. Does Stateful Packet Inspection
of different protocols such as TCP, UDP, and ICMP. Applying all the firewall level attack checks
such as SYN flood attack, Port Scans, Sequence Number checks, Header length checks etc. Maintains
the intermediate databases such as Associations, Selectors etc which are used for Stateful packet
inspection. And also logging log messages where ever necessary.
Responsibilities:
* Understanding the Present Design
* Implementing the enhancements
* Code reviewing
* Bugs fixing and testing
