With everyone living online these days, web traffic to the online channels is on the upsurge. However, if you delve into the traffic, you’ll see that most of the traffic is not from legitimate users. Only less than half of the traffic is actual humans, the rest are bots including both good and bad bots.
In the early days, the bots were used only for spamming or small scraping attempts. Today, bot operators are taking advantage of automation at scale to perform malicious activities. Such activities include taking over user accounts, abuse APIs, perform DDoS attacks, scrape unique pricing information, competitive data mining, web scraping, digital fraud, financial data harvesting, transaction fraud, brute-force login, and many more.
Despite serious impacts, Are organizations adopting an effective bot management approach? The answer is, No.
Many businesses are still trying to block bots with traditional solutions, putting security at risk. So why does the traditional WAF approach for bot mitigation fail?
Let’s look into the reasons behind the failure of WAF in bot management and the benefits of Advanced WAF protection.
To understand the importance of Advanced WAF for bot detection and mitigation let’s explore the common security measures taken by businesses to block bot attacks and why they’re ineffective.
Though Next-generation firewalls (NGFW) claim to be application-aware, they still rely on basic bot mitigation capabilities like blocking IPs, users generating repetitive requests, or fingerprinting the browsers. They examine the first few bytes of the payload, as a result, next-generation bots, which use modern techniques remain undetected.
The WAF technologies undergo several improvements, but it depends on the filter-based approach to detect malicious payloads that have proven inadequate against blocking bots and other automated threats.
Further, managing WAF policies compiled with operational complexity have caused several companies to leave web apps unprotected. In several cases, a known vulnerability was exploited because the targeted enterprise couldn’t patch the vulnerabilities quickly enough.
Combining these challenges, the easy availability of bots for hire and innovations in automation technologies has made bot detection and mitigation much harder.
To deploy effective bot management and protection, organizations need Web application firewall technology, which evolves and fine-tunes itself automatically to detect the most sophisticated bots and delivers continuous security. The good news is, Advanced WAF like AppTrana employs effective measures to detect and stop evolving botnets.
In the case of Advanced WAF protection, the combination of WAF technology and behavior analysis, which detects malicious bot activity makes it easier to spot bot traffic without human intervention.
Bot detection of Advanced WAF includes components like:
With proactive bot defense, advanced WAF tracks attackers beyond their IP address, detects the nature of the user and differentiate legitimate bots from malicious one. It also eliminates the impact to the UX (User Experience) connected with CAPTCHA challenges.
Besides the out-of-box fully managed WAF features that block attacks, companies can create their own custom policies and rules to block bot attacks, which they’re receiving or that they fear they may receive.
For instance – it is possible to make a rule to block access to the password reset request on the website if repetitive requests are made from the same IP within a short span.
With a threat intelligence database, which holds details of all the recent attacks, associated IP address, locations, whether those attacks were machine or man generated. This database is updated all the time. If any request is made from any suspicious IP address, that address will be blocked automatically.
Security Capabilities | Traditional WAFs | Advanced WAF |
Protection from OWASP Top 10 Vulnerabilities | Yes | Yes |
Protection from Simple bots | Yes | Yes |
Customized actions against suspicious bot types | No | Yes |
Collective bot intelligence (behavioral patterns, fingerprints, & IP) | No | Yes |
Risk of false positives | High | None |
Detection of sophisticated bot attacks | No | Yes |
Mitigation of dynamic IP | Limited | Yes |
Fingerprinting of malicious devices | Yes | Yes |
HTTP Traffic Inspection | Yes | Yes |
Web applications are targeted around the clock and the hackers are figuring out new ways to breach the website and cause chaos. Onboarding Indusface fully managed cloud based WAF, AppTrana you are not only reducing the risks of botnets, but also minimizing the processing loads on your infrastructure by blocking malicious bot traffic.
