The issue may also be the analyst/administrators. Were they of sufficient skill to admin the IDS/IPS products (really Aditya's items 2 through 4) and were they knowledgeable enough to actually "monitor and analyze IDS/IPS logs and reports"? If an analyst is not sure of the impact of a possible event the likelihood that it would be reported up the food chain is nill. Should it actually be reported up the food chain, if the analyst is not able to verbalize the impact, the report will only make it one level up and nothing will be done with it. All too often an org will minimize cost at the personnel level by leveraging staff already on board but maybe not qualified for the role. I would also make the conjecture that there was limited buy in of the need for IDS/IPS in the environment. But, Aditya makes the point, "what are you protecting"? The President or ... the junior analyst =) Maybe they did not need it in that environment. I am assuming a "large telecom" has many segments in their network, some of which would absolutely need IDS/IPS. Others... maybe not so much. jk -----Original Message----- From: listbounce () securityfocus com [mailto:listbounce () securityfocus com] On Behalf Of aditya mukadam Sent: Wednesday, March 04, 2009 7:55 AM To: focus-ids () securityfocus com Cc: Ravi Chunduru Subject: Re: ROI on IDS/IPS products It was felt that they did not find enough ROI to
justify 2 dedicated personnel to monitor and analyze IDS/IPS logs and reports. It apperas that no major incidents were detected by network IPS devices. i also was told that these IPS devices are from industry leaders.
I read the above with below example : A residential building has a gate,wall and few security personnel for safety against theft etc. In two years, there was no major theft or issues and hence the residents decided to remove the building gate, security personnel ! Oh yes, the security guards were black cat commandos ! Your discussion with the security administrator was very interesting however it would be good to know: 1) How and were are the IPSs placed in the network ? 2) What Signature profile are they using for these IPSs ? Many IPSs comes with default settings for low detection. 3) Did they tune the IPSs as per their own requirement ? 4) How often they patched the IPSs ? Lastly, are the IPSs purchased because they were needed *or* the company was fooled to buy it or had budget/ policies/ vendor commitment to buy it ? It all depends what are you safe guarding ! For example: A common man's residential building will have 1 security guard however the President's residence will have range of security gadgets, various check points, many many security guards !!!

I was talking to a junior security administartor working for a big telecom company. He said something which is worrying. After few years of IPS deployment in particular department, they decided to remove IPS devices. It was felt that they did not find enough ROI to justify 2 dedicated personnel to monitor and analyze IDS/IPS logs and reports. It apperas that no major incidents were detected by network IPS devices. they felt that signature coverage is either poor or not timely. i also was told that these IPS devices are from industry leaders. Can you share your experiences? Any examples of successful detection and prevention of major attacks and penetration by IPS devices. Thanks Ravi
