RE: How to choose an IDS/FW MSS provider

A managed solution still presents the same problems that an IDS/IPS solution would do in house, but also gives a scary amount of control to the MSS vendor as to what they consider dangerous, or not. Only with a full internal network audit and assessment of all nodes can the accuracy of an IDS be improved, and this is where local knowledge is a must. One would be crazy if you just thought you could buy an IDS/IPS black-box solution, stick it on the perimeter of your network, and expect blanket coverage. Although ISS have a great SOC, and world-reknowned XForce team, they do not have the resource to visit each and every customer to ensure the accuracy of their managed solution, as is the same with most other large, multinational MSS providers. In fact, a lot of the time, an incident will occur, the MSS will flag it, alert the client, the client will work out whether or not it's a false positive, and maybe 12 hours or so later, the anomaly will be identified, by which time if it was malicious than the damage would already have been done, or if benign, time wasted, so I sometimes fail to see the value a managed IDS service can provide (unless it's done PROPERLY, but the true cost of this is often prohibitive). This is where local expertise is a must - I would favour a small, local MSS that could give me instant support during a crisis, rather than from someone who only offers a SOC hundreds of miles away...

When selecting a MSS provider (IDS/FW alike) of course you must be convinced that the use the right tools/products. Some providers use commercial ones like Netscreens, CP, ISS,...... others use there own spin-offs or open source. More importantly is almost how they provide there services, the SLA and operational procedure agreements, there incident handling capability and of course the security experience they bring to your company. For example ISS is strong as a product vendor but is just moving to the market for delivering services. When selecting a MSS also normal classic outsourcing aspects must be considered. Since you are outsourcing part of your security monitoring and incident handling process special care should be taken here. For example there are large companies or product vendors who "also do security services", but there are also dedicated MSS companies. Often small specialized companies but with a large insight in the issues that really matter. Remember, it's no t just the product that you buy, it's about the service and quality of the monitoring and incident handling that protects your company assets. Everyone will sooner or later get (there own) products working, that's not the issue here. Smaller companies can also better control who is monitoring your networks and systems. Big MSS providers just have a pool of people monitoring, maybe even from different SOCs. However some customers require that they must be convinced that only a limited number of persons are involved providing the service. My company for example only works with top-level screened security staff. Therefore we are able to guarantee who is doing what, when and how. And what about incident handling and response? If something might happen is your MSS there for Protect & proceed or Pursue & prosecute? Product vendors or normal IT companies entering the MSS market often lack this experience. Global market presence is often only limited needed since MSS is only providing a small part of the total infrastructure. Therefore small MSS companies may just pickbag on already in place service structures. The MSS services themselves are completely independent of location. Author works at a highly specialized dedicated Forensic and MSS company providing services to global customers and law enforcement. -------------------------------------------------------------------------- Test Your IDS Is your IDS deployed correctly?
