In this technology driven world, Software market is blooming at the rapid rate. As the market blooms there is an increasing need to secure the network. Network security is now the next step which to help the software market. Data being transferred from offshore location to the onsite location over a thin metal wire in backend increases the demand to secure the network. It is said that the most secured computer is the one which is unplugged and thus making it useless for anything.
Network security is not just a demand but it has been an important necessity for all users. Different business user demands different type of security and of different level. Keeping in mind some of the impact of data breach and other cyber-crimes, government of different countries has made different laws as per the impact is done which is considered as a good move. Mainly there are two types of security over the network. First is to prevent the network from external intruders and second is determining the culprit through forensic analysis. This mainly illustrates the forensic of network security.
Network Security is defined as the protection of computer network from unauthorised modifications, disclosure and destruction. In today’s world for all company users , one need to have full access to the data and at the same time we need to provide the security for those data so that it cannot be breach able by external agents. They also need to secure the data both from internal access and external access. The security over the external access (WWW) is a task which needs to be mastered upon. Here comes the role of firewall which creates a protective layer for the software so that it cannot be intruded.
The security from the internal access is the toughest task. Here more than securing the data managers need to keep an eye on the flow of information too and then identify possible moles inside. Before providing access to the internal data , users are made clear and signed not to misuse the data and information which are critical for the company. If found guilty doing such things, it is a punishable offence under the court of law. Some of the security breaches and attacks are – Data Manipulation, Unauthorised access, virus attacks and Destruction of information.
All of these data are present in the system in form of a log files which can be accessed by the authorised user of the file. Reading and making sense out of these files need high manual brain and professional experience. So in order to monitor these logs , we have something called Log monitoring which creates sense of these files and make it understandable. This is required as no matter how much defensive is the security to your system but it requires something to read the logs and make meaning of it. So to make sure the information and data is flowing properly with perfect security we need to keep eye over the users using the application either manually which is quite impossible or through data log files.
