The following types of logs are provided:

Attack event log: Events detected by attack defense functions, such as IPS, are recorded. You can modify the protection action if traffic is improperly blocked. For details, see Modifying the Protection Action of an Intrusion Prevention Rule. For details about how to modify the protection action of antivirus, see Modifying the Virus Defense Action for Better Protection Effect.
Access control logs: All traffic that matches the access control policies are recorded. For details about how to modify a protection rule, see Managing Protection Rules. For details about how to modify the blacklist or whitelist, see Editing the Blacklist or Whitelist.
Traffic logs: All traffic passing through the firewall is recorded.

If improper blocking is recorded in access control logs, check whether your protection rules, blacklist, and whitelist configurations are correct.
If improper blocking is recorded in attack event logs, your normal workloads may be blocked by IPS.
- If the traffic from an IP address is improperly blocked, add it to the whitelist.
- If the traffic from multiple IP addresses is blocked, check logs to see whether it is blocked by a single rule or multiple rules.
  - Blocked by a single rule: Modify the protection action of the rule. For details, see Modifying the Action of a Basic Protection Rule.
  - Blocked by multiple rules: Modify the protection mode. For details, see Adjusting the IPS Protection Mode to Block Network Attacks.
