The Mirai botnet was first discovered back in 2016, but has continued to persist and abuse common vulnerabilities and exposures (CVEs) on IoT devices, including home routers and many other network-connected devices. These addresses were apparently port scanning IP addresses that belonged to the company sending the letter.

As application traffic is increasingly carried over HTTP(S), traditional, port-based methods of identifying application traffic are not always effective. Different network protocols have different functions and present varying security risks. What is Application Awareness?

In some cases, network scanners will use port scans and in other cases ping sweeps. The University of Pennsylvania, for example, uses network scanning in the study of global trends in protocol security. This can be easily done by configuring Remote Port Forwarding in the Cato management console. What is Network Scanning?

A converged solution enables doing this in a holistic manner that covers all traffic (ports, protocols, IPs, sources and destinations), applications (Private, Public, Cloud and Web), security capabilities (FWaaS, IPS, NGFW, ZTNA, CASB, DLP) and directions (WAN, Internet, Cloud) for all users, IoT, apps and devices.

The CDN and the ISP peers over an IXP, the volume drives port upgrades, and private connections are impossible. Removing traffic from the edge will save money on transit and IXP port fees and lower the risk of congestion. The first two scenarios are straightforward. More on what to consider when building the business case later.

However, the dynamic nature of cloud computing, the security challenges posed by mobile users , and IoT (Internet of Things) have blurred the lines that define network perimeters and created new attack surfaces. The premise is intuitive enough: if you secure the perimeter strongly enough, the entire network is secure.
