This topic walks you through how to combine dedicated WAF instances and layer-7 load balancers to protect your services over non-standard ports that cannot be protected with WAF alone. For ports supported by WAF, see Ports Supported by WAF.
WAF provides three anti-crawler policies, bot detection by identifying User-Agent, website anti-crawler by checking browser validity, and CC attack protection by limiting the access frequency, to comprehensively mitigate crawler attacks against your websites.
After you authorize WAF to access Log Tank Service (LTS), you can use the WAF logs recorded by LTS for quick and efficient real-time analysis, device O&M management, and analysis of service trends.
