Functions

WAF helps you protect services from various web security risks. The following table lists the functions of WAF.

Function

Description

Service configuration

Protection for IP addresses and domain names (wildcard, top-level, and second-level domain names)

WAF offers the cloud and dedicated modes to protect websites. You can add either domain names or IP addresses to WAF. Before you start, get familiar with the following differences:
  • Cloud mode: protects your web applications on or off the cloud through domain names.
  • Dedicated mode: protects your web applications on the cloud through domain names or IP addresses.

HTTP/HTTPS service protection

WAF can protect HTTP and HTTPS traffic for a website.

WebSocket/WebSockets

WAF can check WebSocket and WebSockets requests, which is enabled by default.

Non-standard port protection

In addition to standard ports 80 and 443, WAF also supports non-standard ports.

Web application security protection

Basic Web Protection

With an extensive preset reputation database, WAF defends against Open Web Application Security Project (OWASP) top 10 threats, vulnerability exploits, web shells, and other threats.

  • General Check

    WAF defends against attacks such as SQL injections, XSS, file inclusions, Bash vulnerabilities, remote command execution, directory traversal, sensitive file access, and command/code injections.

  • Web shell detection

    WAF protects against web shells from upload interface.

  • Precise identification
    • WAF uses built-in semantic analysis engine and regex engine and supports configuring of blacklist/whitelist rules, which reduces false positives.
    • WAF supports anti-escape and automatic restoration of common codes, which improves the capability of recognizing deformation web attacks.

      WAF can decode the following types of code: url_encode, Unicode, XML, OCT, hexadecimal, HTML escape, and base64 code, case confusion, JavaScript, shell, and PHP concatenation confusion

CC attack protection rules

WAF can restrict access to a specific URL on your website based on a unique IP address, cookie, or referer field, mitigating CC attacks.

Precise protection rules

WAF enables you to combine common HTTP fields (such as IP, path, referer, user agent, and params) to configure powerful and precise access control policies. You can configure precision protection rules to protect workloads from hotlinking and block requests with empty fields.

Blacklist and whitelist rules

You can configure blacklist and whitelist rules to block, log only, or allow access requests from specified IP addresses.

Geolocation access control rules

You can customize these rules to allow or block requests from a specific country or region.

Web tamper protection rules

You can configure these rules to prevent a static web page from being tampered with.

Website anti-crawler protection

WAF dynamically analyzes your website service models and accurately identifies crawler behavior based on data risk control and bot identification systems.

Information leakage prevention rules

You can add two types of information leakage prevention rules.

  • Sensitive information filtering: prevents disclosure of sensitive information (such as ID numbers, phone numbers, and email addresses).
  • Response code interception: blocks the specified HTTP status codes.

Global protection whitelist rules

This function ignores certain attack detection rules for specific requests.

Data masking rules

You can configure data masking rules to prevent sensitive data such as passwords from being displayed in event logs.

Traffic identifier for a known attack source

WAF allows you to configure traffic identifiers by IP address, session, or user tag to block possibly malicious requests from known attack sources based on IP address, Cookie, or Params.

PCI DSS/PCI 3DS compliance certification and TLS checks

  • TLS has three versions (TLS v1.0, TLS v1.1, and TLS v1.2) and seven cipher suites. You can select the one best fits your business needs.
  • WAF supports PCI DSS and PCI 3DS compliance certification check.

Configuring a traffic identifier for a known attack source

WAF allows you to configure traffic identifiers by IP address, session, or user tag to block possibly malicious requests from known attack sources based on IP address, Cookie, or Params.

Advanced settings

PCI DSS/PCI 3DS compliance certification and TLS checks

  • TLS has three versions (TLS v1.0, TLS v1.1, and TLS v1.2) and seven cipher suites. You can select the one best fits your business needs.
  • WAF supports PCI DSS and PCI 3DS compliance certification check.

Configuring a traffic identifier for a known attack source

WAF allows you to configure traffic identifiers by IP address, session, or user tag to block possibly malicious requests from known attack sources based on IP address, Cookie, or Params.

Configuring connection timeout

  • The default timeout for connections from a browser to WAF is 120 seconds. The value varies depending on your browser settings and cannot be changed on the WAF console.
  • The default timeout for the connection between WAF and an origin server is 60 seconds. You can manually set the timeout on the WAF console.

Event management

  • WAF allows you to view and handle false alarms for blocked or logged events.
  • You can download events data over the past five days.
  • You can use Log Tank Service (LTS) to record all WAF logs, including attack and access logs.

Notifications

You can enable notification for attack logs. If this function is enabled, WAF sends attack logs to you by the method you configure.

GUI-based security data

WAF provides a GUI-based interface for you to monitor attack information and event logs in real time.

  • Centralized policy configuration

    On the WAF console, you can configure policies applicable to multiple protected domain names in a centralized manner so that the policies can be quickly delivered and take effect.

  • Traffic and event statistics

    WAF displays the number of requests, the number and types of security events, and log information in real time.

High flexibility and reliability

WAF can be deployed on multiple clusters in multiple regions based on the load balancing principle. This can prevent single points of failure (SPOFs) and ensure online smooth capacity expansion, maximizing service stability.
