Nowadays, people like to send messages, talk to friends, watch TV and movie, and share information with others through Internet by ubiquitous mobile devices. Telecom service providers also deploy next generation of network system with more high speed and large capacity for such demand from subscribers.

On the other side, with versatile type of information on Internet, internet threats inside enterprises and cyber fraud in society become more and more rampant. Impact of such cybercrimes is more significant to economic and political situation of state. No matter in enterprises for cyber security or in telecom IDC for lawful interception, the deployment of network forensic systems will be more complicated and multiplicity in order to intercept target traffic extensively.

In reality, we have also helped build up such distributed deployment of network forensic systems for several clients from enterprises and law enforcement agencies in several states. From technical viewpoint, as solution provider, we deeply hope the architecture of implemented systems is as simple as possible. Actually, in customer network environment with high speed and large capacity traffic, we must adopt distributed deployment to balance traffic loading in accord with performance of network forensic systems.
Under such distributed deployment requirement, how to coordinate and manage all distributed systems for major network forensic task is very critical to customer business i.e. centralized management on all involved systems.

“We know how customers expect and manage these highly integrated systems,” said Casper Kan Chang, CEO of Decision Group “so we enhance the capability of centralized management with industrial standard technology – SNMP management in order to provide more stable solution with high degree of integrity for customer mission critical task, no matter for cyber security or lawful interception.”
The current distributed deployment Decision Group provided is with 3 tier architecture:

1. Tier-1: in this layer, there are all front-end data collection and protocol analyzer systems, such as E-Detective, ED2S, iMediator and Wireless-Detective systems.
2. Tier-2: in this layer, there are data retention system and provision data system.
3. Tier-3: in this layer, there are centralized management system and secondary data analysis systems.

The above 3 tier systems form a complete solution for dedicated customer operation, i.e. lawful interception or ITSM.
The SNMP management support in Decision Group Centralized Management System is at 2 different levels:

1. Coordination and management among different systems – in highly distributed deployment, there are many systems with different roles and functions: some are data collection systems from network devices, some are data retention systems, some are data filtering and scoping management systems, and some are data analysis systems. Thus, coordination and management for seamless processes among different systems is very important.
2. Integration with SOC or NMS system – basically all deployed network forensic systems are not aliens to other network devices in the same IDC site. How to manage all network forensic systems under the same governance scope is very important. So, integrate with SOC or NMS system is the fundamental requirement for network forensic system to be deployed in customer network environment.

By such requirement, Decision Group has provided system management capability by SNMP support in some projects since 2013 on few network forensic products. As the distributed deployment becomes more popular in 2014, we decide to enhance SNMP support to our full spectrum of product and also add SNMP manager in our Centralized Management System.
This enhancement will not only provides strong system coordination and management capability among Decision Group network forensic solutions, but it also provide high integration capability with other backend SOC and NMS for more IT government and ITSM support.
