Whether the stream-events are added as counters as well. Similar to the decoder-events option, the stream-events option controls To change the naming of the decoder-events from decoder. To address this withoutД«reaking existing setups, a config option decoder-events-prefix was added This lead to a fair amount of decoder-eventД¬ounters not being shown in the EVE.stats records.

In 4.1.x there was a naming clash between the regular decoder counters and The decoder events that the decoding layer generates, can create a counter perД®vent type. Not useful due to how threads are synchronized internally. Statistics can be enabled or disabled here. #decoder-events-prefix: 'decoder.event' # Add stream events as stats.

Is a possibility to change the order of priority. The most important signatures will be scanned first. They will be processed in a different order. Rules will be loaded in the order of which they appear in files. Inline/IPS can block network traffic in two ways. Like any other non-threatening packet, except for this one an alert If a signature matches and contains alert, the packet will be treated Inline/IPS mode, the offending packet will also be dropped like with There are two types of reject packets that This is an active rejection of the packet. Suricata generates an alert for this packet. Receive a message of what is going on, resulting in a time-out Signature that matches, containing drop, it stops immediately.

Packet and skips to the end of all rules (only for the current If a signature matches and contains pass, Suricata stops scanning the Happen when a signature matches and contains one of those Actions: This one determines what will happen when a signature All signatures have different properties.
