Practical guides

The essential steps, in the order to apply them.

  1. Install system and software updates, then switch them to automatic.
  2. Check that the antivirus is active and up to date.
  3. Lock the session with a password and turn on automatic locking after five minutes.
  4. Uninstall unused software.
  5. Encrypt the disk (BitLocker, FileVault) on laptops.
  6. Back up your documents to storage approved by your IT department.

  1. List critical accounts: e-mail, administration, remote access, bank accounts.
  2. Prefer an authenticator app or a hardware key over SMS.
  3. Enable two-factor authentication for administrators first, then for everyone.
  4. Plan a recovery procedure in case a phone is lost.
  5. Tell users before switching it on.

  1. Isolate affected machines from the network without shutting them down.
  2. Alert the crisis team and your incident response provider.
  3. Do not pay any ransom or contact the attackers.
  4. Record every action and its time: this log will help the investigation.
  5. Prepare internal communication, then external communication if personal data is affected.
  6. File a complaint with the competent authorities.

  1. Apply the 3-2-1 rule: three copies, two media, one offline or off-site.
  2. Automate backups and monitor that they complete.
  3. Separate backup administration accounts from the rest of the network.
  4. Test a full restore at least once a quarter.
  5. Document the restore procedure and the order in which services restart.
