Over the last five years, some players have appeared, others have disappeared, partnerships have been built and solutions have continued to evolve. All these elements indicate a market that is still in the process of consolidation.<\/p>\n<figure id=\"post-15466 media-15466\" class=\"align-none\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-15466 size-full\" src=\"https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/3.png\" alt=\"\" width=\"1066\" height=\"544\" srcset=\"https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/3.png 1066w, https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/3-374x191.png 374w, https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/3-71x36.png 71w, https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/3-768x392.png 768w\" sizes=\"auto, (max-width: 1066px) 100vw, 1066px\" \/><\/figure>\n<p style=\"text-align: center;\"><em>Figure 3: Our market knowledge<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<h3>Actors with different approaches<\/h3>\n<p style=\"text-align: justify;\">As might be expected in such a diverse market, different approaches to the sales model emerge. Some players put more emphasis on their product as such, while others emphasise its integration in their catalogues of services (threat intelligence, SOC, CSIRT&#8230;) or complementary products. These approaches naturally influence the contact between the players and their customers: the more the offer emphasises a service, the more the player will seek to have direct contact with his customer.<\/p>\n<p style=\"text-align: justify;\">\n<h2 style=\"text-align: justify;\">Our vision of the field: a need for maturity<\/h2>\n<h3>Our feedback<\/h3>\n<p style=\"text-align: justify;\">At least initially, we recommend focusing on critical sites and processes for reasons of time, cost and skill savings. Moreover, in order to offer relevant behavioural detection, the probes require a significant learning time depending on the site on which they are deployed (identification of false positives, false negatives, accumulation of data for learning&#8230;). In addition to this time, significant human resources are required during this learning phase, but also later during the daily use of the product (mainly alert management). It will also be important to link the probe management teams and the incident response teams in order to deal with incidents detected by the probe and then confirmed.<\/p>\n<p style=\"text-align: justify;\">Prior to deployment, the positioning of the probes should be studied. Indeed, it will be the key to both a complete mapping and an optimal detection surface. These initial considerations must address important points such as hardware compatibility (switches, for example) with the probes and the architecture of the site (on which the number of probes may depend). In addition to providing a real-time inventory, mapping can help implement or review network segmentation, an essential step in a security project. The qualification phase should also make it possible to check that the chosen probe will understand all the industrial protocols used and to discuss the processing of encrypted flows, if any.<\/p>\n<p style=\"text-align: justify;\">Finally, of course, this type of project cannot be carried out without the integration, from the outset, of the OT teams.<\/p>\n<p style=\"text-align: justify;\">A number of our clients stop at the test phase, but others have started to deploy probes on their critical sites or even on their entire industrial information system. The reasons given for not deploying probes are mainly related to costs, charges and required skills. The sovereignty of a detection probe can also be an important issue in certain environments.<\/p>\n<h3>Identified limits<\/h3>\n<p style=\"text-align: justify;\">In addition to the above points, technical limitations may also arise. Issues of bandwidth and network overload, induced by the collection of logs, can be anticipated. Moreover, an OT probe is by nature limited to network exchanges, its results (detected threats, security level evaluation&#8230;) are therefore to be put into perspective in relation to the resources at its disposal.<\/p>\n<p style=\"text-align: justify;\">Finally, the probes ensure detection. On the other hand, the reaction must be carried out by other means, human or technological. More generally, with their many interesting functionalities, the probes are complementary to good security practices such as: the installation of antivirus and firewall, the implementation of a well of logs and adequate collection configurations, the construction of network documentation, the establishment of dedicated SOC and CSIRT teams&#8230; All these practices remain in force and will allow the full exploitation of the probes&#8217; capacities.<\/p>\n<figure id=\"post-15464 media-15464\" class=\"align-none\"><img loading=\"lazy\" decoding=\"async\" class=\"aligncenter wp-image-15464 size-full\" src=\"https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/4.png\" alt=\"\" width=\"995\" height=\"602\" srcset=\"https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/4.png 995w, https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/4-316x191.png 316w, https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/4-64x39.png 64w, https:\/\/www.riskinsight-wavestone.com\/wp-content\/uploads\/2021\/04\/4-768x465.png 768w\" sizes=\"auto, (max-width: 995px) 100vw, 995px\" \/><\/figure>\n<p style=\"text-align: center;\"><em>Figure 4: Our main feedback on the deployment of an OT probe<\/em><\/p>\n<p style=\"text-align: justify;\"><em>\u00a0<\/em><\/p>\n<h2 style=\"text-align: justify;\">Conclusion<\/h2>\n<p style=\"text-align: justify;\">The probes offer a range of functionalities that meet real needs. Our meetings indicate that the market players continue to take into consideration the needs that have been brought to their attention in order to improve their product. Despite a consolidating market, the players seem to be technically converging towards extremely similar end products. Differences will be played out on ergonomic details, on the approaches adopted by each and on costs.<\/p>\n<p style=\"text-align: justify;\">Our initial feedback shows the importance of the load and the skills required to use a probe. While they may be useful in an immature context, in order to help with system knowledge and the implementation of good network hygiene, they only really reveal their potential once they are fully integrated into the arsenal of detection and incident response teams, which corresponds to a highly mature context. Thus, it would seem to be a higher priority to follow the good practices outlined above in order to gain in maturity and then to consider deploying a probe in a second phase.<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: justify;\"><em>1: See <\/em><a href=\"https:\/\/en.wikipedia.org\/wiki\/Purdue_Enterprise_Reference_Architecture\"><em>https:\/\/en.wikipedia.org\/wiki\/Purdue_Enterprise_Reference_Architecture<\/em><\/a><\/p>\n<p style=\"text-align: justify;\"><em>2: See https:\/\/en.wikipedia.org\/wiki\/Port_mirroring<\/em><\/p>\n<p style=\"text-align: justify;\"><em>3: See <\/em><a href=\"https:\/\/en.wikipedia.org\/wiki\/Network_tap\"><em>https:\/\/en.wikipedia.org\/wiki\/Network_tap<\/em><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Among the needs identified by our industrial customers are the mapping of OT systems (Operational Technology) and the detection of attacks.
