Reinforcement of Cybersecurity within the Presidency

The project aligns with the national strategy SNC2022 to increase the security posture of companies and institutions within Senegal. SNC2022 is a vision from the President to improve the cyberspace quality of our country. We realized this goal by implementing many tools in our network, practicing a defense-in-depth strategy, and by elaborating a security policy related to the utilization of our data. I coordinated the realization of our identity and access management policy.

VPN Connection with Multiple Sites

I was in charge of implementing a site-to-site VPN using a complex architecture. This solution helps our external services access our internal solution. I used the Fortinet firewall, and the authentication was done using IKE and IPsec. Fortinet allows us to check the solution permanently.
