Security vulnerability is the weakness in the network by which unauthorized access in the network is emphasized. Some of the reasons causing security vulnerability are discussed below:
- Untrained staffs
- Implementation of new software
- Poor access control mechanism
- Poor password policy
- Default setting of operating system
Likewise, there are several ways of monitoring security vulnerability which are discussed below:
Use of port scanner:
Port scanner is a software that probes for open ports. It is used by network administrator to test the network.
Use of Network scanner:
It is used to resolve host name, auto detect internal and external IP address, discover share folders.
Network should be tested regularly by network administrator to find the security vulnerability in the network.
Traffic analysis helps in monitoring the possible security vulnerability in the network.
