How Internet Background Noise Makes Cybersecurity Hard?

Internet background noise is the result of scanners and crawlers that are looking for vulnerabilities, as well as malicious actors who are trying to take advantage of those vulnerabilities.

While some internet noise is simply the result of automated systems doing their job, there is also a significant amount of noise that is generated by people who are trying to exploit weaknesses in systems. This can include everything from scanners that are looking for open ports to malicious actors who are trying to exploit websites vulnerabilities during a reconnaissance phase.

The sheer volume of unsolicited traffic specifically designed to probe for weaknesses in cybersecurity defenses is a challenge for any organization. The average organization using cybersecurity tools like a SIEM will see tens of thousands of unique IPs in a given day, with the vast majority of them being malicious. And, because each IP can generate hundreds or even thousands of events, the number of potential security threats can quickly become overwhelming. To make matters worse, many of these attacks are automated and can run 24/7, making it nearly impossible for security teams to keep up.

Good. One common source of internet noise is shodan, which is a search engine that allows users to find devices connected to the internet. censys is another common source, which is a database that contains information on devices connected to the internet. Palo Alto Networks is also a source of internet noise. Furthermore, since 2001 we also see more Universities and researchers constantly scanning the internet to have a picture of the World Wide Web.
