The cybersecurity of an SME begins with simple, verifiable and properly maintained measures. Rather than multiplying tools, fragile access must be reduced, exposed components must be corrected, backups must be protected and a realistic response to incidents must be prepared.
Start with access and authentication
Invent admin accounts, remove those that no longer serve and enable multifactor authentication as a priority on emails, cloud tools and technical access. Use a password manager and prohibit the sharing of identifiers between employees.
Update exposed components
Identify websites, servers, posts and dependencies accessible from the Internet. Apply critical fixes, remove unused services and monitor versions at the end of support. A forgotten component often represents more risk than a recently configured tool.
Check backups with a restore
Keep several copies, including one isolated from usual accesses, and set the appropriate retention time. Schedule restoration tests on representative data. A backup present but unusable does not reduce the downtime or loss of activity.
Reduce unnecessarily accessible data
Apply the principle of every privilege and limit the retention of information that is no longer necessary. Encrypt sensitive exchanges and backups, log administrative actions and check access to providers.
Prepare an incident response
Identify contact persons, priority systems and first actions in case of an incident. Prepare a means of communication independent of the usual tools. A short exercise identifies missing decisions before a real situation.
to remember
Accurate scoping, demanding execution and regular measurement reduce the risk of the project. Codin Studio brings together strategy, design and technology to keep this continuity from the first workshop to continuous improvement.
