They often retain a legacy data center firewall for East-West traffic protection, alongside an SSE solution for North-South traffic protection. Figure 1 – WAN Firewall Policy Using the centralized Cato Management Application (CMA), it is simple to create a policy based on a zero-trust approach. See Figure 1 below.

Additionally, policy rules can be further refined based on application context including application (custom applications too), application categories, service, port range, domain name, and more. Catos WAN Firewall provides granular control of traffic between all connected edges.

At the beginning of the month, Microsoft released an advisory and security patch for a serious Windows Server Message Block (SMB) vulnerability called the Windows SMBv3 Client/Server Remote Code Execution Vulnerability (AKA Windows SMBv3 RCE or CVE-2020-0796). This would solve the problem for SMB servers but not SMB clients.

In the light of recent ransomware attack campaigns against Microsoft RDP servers, Cato Research assessed the risk network scanning poses to organizations. In some cases, network scanners will use port scans and in other cases ping sweeps. As for SQL Servers, it seems like the hunt for databases still exists.

SASEs built-in SD-WAN functionality offers network optimization, while the integrated security stack including Next Generation Firewall (NGFW), Secure Web Gateway (SWG), Zero Trust Network Access (ZTNA), and more secures traffic over the corporate WAN. According to Gartner (that coined the term), SASE is the future of network security.

The top five observed threat types include: Network Scanning : The attacker is detected testing different ports to see which services are running and potentially exploitable. As a result, it seems logical that creating firewall rules blocking traffic to and from these countries would dramatically improve a companys security posture.

Kentik’s NPM solution goes beyond typical NetFlow traffic analysis in that it is enabled through the installation of an nProbe application on Linux based servers. Well, as the probe is installed on the server itself, it is privy to information which NetFlow devices are not. Network latency per client/server/application (ms).

Since most firewall configurations allow HTTP and TLS to any address, many bots use these protocols to communicate with their targets.

And it’s not like the network teams had to worry about fixing failed line cards or erroring ports. Fifteen years ago you couldn’t launch a new business or even run a school without having a server, a switch, and a router sitting in a rack somewhere. So we asked hundreds of questions to try and understand what was going on.
