AWS WAF Bot Control: Defending Against Distributed Proxy-Based Attacks

Security often sits at the top of the list on the agenda of businesses of all sizes. Given the increasing sophistication of cyber threats, it is imperious to have the most state-of-the-art protection to ensure your digital assets remain secure. One such sophisticated cyber threat is the distributed proxy-based attack, which typically involves threat actors using bots for malicious activities.

Today, Application-Wide Web (AWS) Web Application Firewall (WAF) Bot Control, Amazon’s machine learning solution for mitigating distributed proxy-based attacks, offers you protection against such threats. Ai-powered AWS WAF Bot Control now adds a new layer of protection against bots using machine learning techniques without requiring any ML skills or writing any custom rules.

Understanding Distributed Proxy-Based Attacks

Before delving into the defence mechanisms that AWS WAF Bot Control offers, it’s crucial to understand the essence of distributed proxy-based attacks. Threat actors often exploit residential computers or servers that have compromised security. They install botnets (a chain of internet-connected devices, each of which is running one or more bots), granting them the ability to initiate proxy-based attacks.

Using the residential proxy feature, these threat actors can bypass IP reputation checks and custom blocklists. They can rotate IP addresses using automated software to distribute their activities across a broad network of devices. It allows them to send a low volume of requests per IP, effectively evading rate limiting rules formulated to check the number of requests from a single IP address.

Moreover, these threat actors also use global proxies to source traffic, making geo-blocking less effective. Such attacks can disrupt services, compromise security and cause extensive downtime. Therefore, the need for efficient strategies and protective measures against these attacks is paramount.

AWS WAF Bot Control: Your Shield Against Bots

Amazon’s AWS WAF Bot Control is a powerful tool armed with superb features to guard your data against such malicious activities. It adds bot confidence levels to requests that it identifies as being from potential bots, using automated machine learning analysis of your website’s traffic statistics. These confidence levels are tagged as labels indicating high, medium or low bot likelihood.

The incorporation of machine learning (ML) into this security system allows for an efficient and accurate analysis of vast amounts of data to determine the likelihood of a bot. Depending on the bot likelihood level, you can define different enforcement actions providing flexibility in dealing with various threat levels.

This feature thus provides an extra layer of defence by identifying and repelling malicious bot activities while ignoring benign bot activities. It enables AWS WAF Bot Control to maintain high precision in differentiating between malicious and harmless bots by analyzing such behavioral signals as the URLs requested by clients, the time of requests or HTTP headers in the client’s requests.

How AWS WAF Bot Control Works

The functioning of AWS WAF Bot Control is simple yet effective. When a request is made to your web application, AWS WAF Bot Control inspects characteristics that generally indicate whether the request originates from an automated bot or a human. This process is executed by using machine learning algorithms to analyze website traffic data.

The ML model analyzes traffic behaviour and patterns to ascertain the likelihood of a bot’s presence. Internet Protocol (IP) calling patterns, request headers, and aggregate data are some of the elements considered during the analysis.

Once the inspection is complete, AWS WAF Bot Control assigns one of the three bot likelihood labels to the requests – ‘High’, ‘Medium’ or ‘Low’.

These labels, also called bot confidence levels, indicate the likelihood of a request originating from a bot. You can use these labels to apply different enforcement actions. For instance, for requests labeled as ‘high’ bot likelihood, you can block, rate limit, or enable captcha for them.

Setting Up AWS WAF Bot Control

Implementing AWS WAF Bot Control requires minimal effort. The service is fully managed, so there are no agents to install on your application. You don’t need machine learning expertise to use this feature. AWS WAF Bot Control does all the heavy lifting under the hood, freeing you to focus on what matters most to your business.

The setup follows a three-step process:

  1. Define WebACLs: Start by defining a Web Access Control List (WebACL), which is essentially a compilation of rules determining what kind of traffic is allowed.

  2. Add AWS WAF Bot Control Statement: Next, create a rule with AWS WAF Bot Control Bot Statement and add the rule to your WebACL. The Bot Control Statement specifies what to inspect in each web request and what to do when a likely bot is detected.

  3. Associate WebACL with Your Resource: Lastly, associate the WebACL with your resource.

Other Features of AWS WAF Bot Control

  • Visibility and Insights: AWS WAF Bot Control provides visibility into the activities of bots on your websites or applications by delivering detailed traffic reports and charts. It gives you insights into the types of bots that are interacting with your web resources.

  • Bot Category Labeling: Along with the bot confidence label, AWS WAF Bot Control also assigns a bot category label. These categories can include ‘Scraping’, ‘Spamming’, ‘Impersonator’, and others.

  • Scalability: The service is designed to scale with your web traffic volume. Irrespective of the number of requests your web application handles, AWS WAF Bot Control can keep up, ensuring continuous protection.

AWS WAF Bot Control acts as a robust canvas for preventing distributed proxy-based attacks. Integrated with machine learning capabilities, it provides an effective solution eliminating the need for your ML skills or creating custom rules. Remember, the more protected you are, the better the chances of withstanding sophisticated cyber attacks.
