What kind of threats do crawling attacks pose to websites?

Mehmet Ali Erdin, CTO of Emlakjet.com, discusses web crawling attacks—a major internet threat—on Wise TV. He shares critical insights on the risks involved, such as data theft, the publication of stolen data on the Dark Web, and HTML-based attacks, as well as the necessary preventive measures.

Web crawling represents one of the most significant threats to websites exposed to the internet. The risks include the theft of data and the subsequent dissemination of that stolen information across various platforms, such as the Dark Web, where it is passed on to other users. Beyond this, there is also the need to address and prevent HTML-based attacks targeting websites. To mitigate these risks, security measures must be implemented at the front end—such as firewalls—to protect the user interface. On the back end, where APIs operate, it is essential to enforce request limits and implement authentication protocols, ensuring that requests are accepted only after proper authentication has been verified.

The Importance of Web Security

With the widespread adoption of the internet, websites and applications face increasing threats every day. Foremost among these threats is the theft of website data and its subsequent use for malicious purposes. The sharing of such data—particularly on platforms like the Dark Web—can cause serious harm to both users and businesses. In this article, we will examine the importance of web security and the measures that should be taken in detail.

Crawling and Data Theft

Crawling is a process that automatically scans and indexes website content. However, malicious actors can exploit this technology to steal data from websites. This data may include sensitive information such as user details, financial records, or trade secrets. To prevent such data theft, websites must strengthen their security measures.

Use of Firewalls

A firewall is a security barrier used to protect a network. Positioned at the front end of a website, it monitors incoming and outgoing traffic and blocks potentially harmful requests. This protects the website against external threats.

API Security

APIs are interfaces that enable web applications to communicate with other systems. However, these interfaces can also be vulnerable to attacks. Ensuring API security requires implementing request limits and authentication mechanisms. This ensures that only authorized users can access the APIs.

Authentication and Authorization

Implementing authentication and authorization mechanisms is crucial for enhancing website security. These mechanisms verify user identities and ensure that only authorized users can access specific data. This helps prevent data theft and unauthorized access.

Security Testing and Monitoring

To ensure website security, regular security tests must be conducted and systems monitored. These tests help identify potential vulnerabilities and facilitate their remediation. Additionally, monitoring systems enable the rapid detection of and response to anomalous activity.

Conclusion

Web security is of great importance in today’s digital world. Measures such as the use of firewalls, API security, authentication, and authorization should be implemented to protect against threats like crawling and data theft. Furthermore, website security must be continuously maintained through regular security testing and monitoring systems. In this way, user and business data can be kept secure, and potential damage can be prevented.
