Dive in with them as they demonstrate how to set bidirectional quality of service, utilize Catos Zero Trust Network Access (ZTNA) capabilities, and deep dive into bandwidth management and analytics. Jerry shows how easy it is when you use the right DNS settings, making sure that access is enforced correctly, unaffected by IP address changes.

That’s why True Origin is a major step forward for every ISP carrying a significant volume of Internet-sourced content. What is True Origin?

In this post, we will explore the benefits of embedded caching for internet service providers (ISPs) and discuss various strategies for optimizing the deployment of embedded caches in their networks. Movie Open Connect is unique among the CDNs since they do not rely on the DNS system to direct the end user to the suitable cache.

When the Cato Sockets arrive at your locations, you will be ready to connect them to the Internet and the Cato Cloud. Catos firewall-as-a-service offers both an Internet and WAN firewall for external and internal traffic and operates in the Cato PoPs, removing most of the requirements for on-premise firewalls.

In a typical deployment, memcached would be accessed only by internal application components, however, it appears that thousands of memcached instances are exposed to the Internet at large. In this way, it’s very much like DNS and NTP services that have been abused this way in the past. That makes for massive attack potential.

In one form or another the question: how can SD-WAN deliver the same reliability and redundancy as MPLS when it uses the public Internet? SD-WAN + public Internet alone cant. In fact, reliability is often used as justification for the high price of MPLS bandwidth. My response? You have to have a private backbone. The result?

These attacks aim to overwhelm a service’s bandwidth capabilities with prohibitively high traffic volumes. The attacker can spoof IP addresses, DNS, HTTPS headers, and more to deceive users into interacting with compromised applications. There are three main types of DDoS attacks: Volume-based. Protocol-based.

Now that it’s apparent that neglect of basic security has created so many Internet vulnerabilities, we can expect attackers to be like producers rushing to emulate hit shows. During the attack, we were live with customers who could observe spikes of DNS traffic going out-of or through their networks but saw no reason to do anything about it.

Security meant protecting the companys central Internet access point and deploying endpoint security on clients. With MPLS that would normally mean connecting a location with an active MPLS line and a passive Internet connection thats only used for an outage. With SD-WANs use of tunneling, running active/active is not an issue.
