SECURITY OF NETWORK

Question 1:
The problem with relying on IDS/IPS solutions are as follows:
i) Noise can rigorously limit the intrusion detection the effectiveness of system (Nigam,
Minero & Haenggi, 2014).
ii) Bad packets created from the bugs of software.
iii) corrupt the DNS data.
iv) They cannot see into the encrypted packets.
The example of a good host based IDS that is HIDS is SolarWinds Log & Event
Manager. Now it has renamed to Security Event Manager. It contains similar capabilities as
previous along with some new facilities. It is all in one tool kit of SIEM also the pros of
security used to make simpler detecting and examining the issues of security by the data of
event log.

It contains similar capabilities as previous along with some new facilities that will be
helpful for the user. This software can identify also respond to the threats rapidly. Also it can
see the value quickly and ease the compliance audits and reporting. It has the hundreds pre
made connectors to collect logs from the several sources, parse the data also put this into the
mutual readable layout, generating the central location for user to investigate easily the
potential threats, store the logs and prepare for the audits.
The example of the network based ISD that is NIDS is Snort. It is the open source
NIDS made by the Martin Roesch. It is the packet sniffer which in the real time, monitors the
network traffic, inspecting every packet strictly for detecting the doubtful anomalies or risky
payload. It is centred on the libpcap that is to capture the library packet, used in the traffic
sniffers also analysers of the TCP/IP.
