Determine the added value of multicloud in its management capacity

As part of the first debate, the La Poste group notably highlighted the use of multiple clouds, whether public (Amazon for load overflow, Azure for collaboration, etc.) or private. “For business applications, we are essentially on the private cloud in France to ensure a high level of service”, explained Emmanuel Peyrat, IS manager at La Poste. Why not take the step more frankly towards the public cloud? The reason for preserving data confidentiality coupled with regulatory constraints is put forward. “We must also consider the added value of multicloud in terms of use and whether this simplifies or complicates the burden of IT management,” added Tristan Piron, CDO and head of IT innovation at La Poste. . A question that will probably not remain unanswered as the number of cloud services increases.

Working since 2016 on compliance with the GDPR, Harmonie Mutuelle crossed the milestone of May 25 not without some anxiety: “We experienced the changeover with great pressure due to our particular mutual environment where the question of protection personal data is central,” explained Joris Berthaud, DPO of the mutualist group. “We also had to reassure people internally and raise awareness a notch”. Since October, the group has launched a range of services to meet this challenge: e-learning module, online practical guide, quizzes, displays and kakemonos, etc.

“The GDPR we have been trying to prepare for it since the beginning of 2017, we have a CIL who will be named DPO, this has allowed us to prepare the ground”, indicated Régis Dubrulle, CISO of the Terrena agricultural cooperative which manages notably the poultry brand Père Dodu. “Since May 25, we have received a dozen requests from people to delete their personal data, which was extremely rare before, and all of them invoked the GDPR”. The implementation of a GDPR approach is often a team affair in the company, between the DSI and the legal department but also the RSSI as was the case within the metropolis of Nantes. “My role was to support the DPO on the impact analysis and being ISO 27001 certified since 2015 has helped us to reach a certain maturity on this subject,” said Patrice Renaudineau, CISO of Nantes. Metropolis. “We offer to support local authorities in the implementation of the GDPR with an outsourced DPO service and more than 200 have called on us. The main problem is that in this population there are still a lot of Excel files, lists of names, for example, of the names of children enrolled in school which are used by private schools for canvassing: there are still job to do”, explained his side responsible for the consulting and innovation center of e-collectivities Vendée.

Valves and streetlights connected in Nantes

“We are setting up an infrastructure to collect data from the connected objects of the smart city of tomorrow,” said Nathalie Vincent, director of Nantes Métropole infrastructure and services. By way of illustration, the director notably mentioned connected water valves with SIM cards to monitor overflows, or even connected street lamps to control their ignition and better monitor their electricity consumption. “We launched a POC based on Lora technology and evaluated Sigfox but preferred to start with the first because it was less linked to a proprietary network,” said Nathalie Vincent.

Of note among the intervention slots highly appreciated by Reims IT Tour participants is that of the cybersecurity training firm bluecyforce (rated 9.3/10). After presenting an overview of the types of attacks, issues and means used by hackers to steal (data, money, etc.) and attack (cryptoware, ransomware, etc.) companies, Vincent Riou, CEO of bluecyforce, notably launched in a cyberattack simulation demonstration. Several steps were put forward: domain name typosquatting, exploitation of an unpatched WordPress site vulnerability of the town hall website used for the demonstration and interception of the mayor’s credentials via a redirect on a controlled mirror phishing site by a hacker.

In the context of artificial intelligence projects, the question of the implementation of chatbots for the purpose of automating support or document flows is a burning issue. With the question of the reallocation of human resources on other tasks with higher added value. “We were working on the chatbot to meet internal needs for collaboration, management of requests for information, but also for level 0 and 1 support,” said Emmanuel Peyrat. “The idea is to start getting into more complex topics and provide a seamless switch between automated chatbot processing and a human person for Level 2.” Among the other projects initiated in this area, an HR chatbot to assist with HR requests (holidays, retirement, etc.) and another to better process and give meaning to customer data in a big data context. “Automation and chatbots can be used to more effectively process requests for instruction, town planning, declaration of works, but we must ask ourselves the question of the retraining of agents and also be careful not to increase territorial inequalities because the information highways are still far from covering the entire rural sector,” explained Pierre Sylvestre.

Last debate of the morning: cybersecurity with the intervention carefully followed by the digital security delegate for the Pays de la Loire region of ANSSI, Jean-Sylvain Chavanne. “Many companies have been impacted by ransomware, for example in the food industry with a service company that lost 20 years of its data and another whose labeller was infected and caused 2 weeks of service interruption” . In addition to ransomware infections, the delegate from the National Information Systems Security Agency also pointed out – as in the Grand Est – the lack of site monitoring and the rise of cryptomining that hackers are installing. on the servers of communities that are often overwhelmed in terms of human and financial resources to properly secure their infrastructures. “Among the 42 tips in the digital hygiene guide published by ANSSI, emphasis must be placed on correctly setting up your infrastructures, knowing your assets and the information they contain, monitoring and backing up,” summarized Jean-Sylvain Chavanne.
