Security hardening
In short
FiveM security comes down to two things: server convars that shut whole classes of abuse, and scripts that never trust the client.
| Convar / command | Suggested | Effect |
|---|---|---|
sv_scriptHookAllowed | 0 | Refuses clients running Script Hook V |
sv_pureLevel | 1 or 2 | Blocks modified game files (level 1 allows audio and known graphics mods) |
sv_entityLockdown | strict or relaxed, after testing | strict: clients cannot create entities; relaxed: client-created script entities are blocked |
sv_filterRequestControl | 1–4 | Blocks control requests for entities controlled by players |
sv_enableNetworkedSounds | false | Stops routing NETWORK_PLAY_SOUND_EVENT, a common abuse vector |
sv_enableNetworkedPhoneExplosions | false (default) | Keep phone explosion events disabled |
sv_enableNetworkedScriptEntityStates | false if unused | Stops routing SCRIPT_ENTITY_STATE_CHANGE_EVENT |
setr sv_stateBagStrictMode | true | Only the server can change state bags on networked entities |
sv_endpointPrivacy | true | Hides player IPs from public server output |
rcon_password | unset | RCON stays disabled |
block_net_game_event | Events you never use | Drops a game event on the server |
In scripts, validate every server event: who sent it (source), whether they may do it (job, ACE, distance), whether the values make sense (types, ranges) and how often they call it. Never accept money, prices or item counts from the client. Patterns and code: secure server events.
- Keep the server key, webhooks, bot tokens and store secrets in an
exec’d file or server-only convars — never in client files. - Restrict txAdmin to known IPs and give every staff member their own account.
- Update artifacts and resources; old versions have publicly known exploits.
- Buy from reputable sellers — leaked resources often ship with backdoors.
- Log admin actions and economy changes somewhere staff cannot edit.
