As we look ahead to 2022, we should pause to reflect on the trends of the past year. Ransomware and supply chain attacks have become two of the top concerns for organizations following a series of high-profile attacks, such as those conducted against Colonial Pipeline, SolarWinds and Kaseya. In 2021, our Project Memoria revealed close to 100 different vulnerabilities in common TCP/IP stacks, affecting hundreds of operational technology (OT) vendors.

On November 10, 2021, Palo Alto Networks released advisories for eight different vulnerabilities affecting the company’s VPN firewall products. The vulnerabilities’ criticality ranges from ‘medium’ to ‘critical,’ with the most severe vulnerability, CVE-2021-3064 (CVSSv3.1 of 9.8), allowing for unauthenticated remote code execution, or RCE.

When was the last time you thought about all of the devices running on your network? Think of your home network and how deceptively simple it appears. A full inventory of that network would probably surprise you, as it would show all of the devices that you may have forgotten about as well as a few of the neighbor’s devices that are piggy-backing off of your Wi-Fi. This visibility is often shocking to many people.

There’s a lot of upside to becoming an application-centric business. You can increase collaboration, work more effectively with your data, deliver an optimal customer experience, and much more. One major downside, though, is that your network and security operations teams are under intense pressure to provision new applications both quickly and securely.

Networks form a critical core for our modern-day society and businesses. People, processes, and technologies should be in place for monitoring, detecting, logging, and preventing malicious activities that occur when an enterprise experiences an attack within or against their networks.

CISA recently released a set of playbooks for the Federal Civilian Executive Branch (FCEB) to provide improved cybersecurity incident response (IR) and vulnerability response. As was demonstrated by the SolarWinds SUNBURST attack in December 2020, coordination and reporting across the FCEB continues to be a challenge. Adding to this challenge is the situation where agencies have differing playbooks on how to handle confirmed malicious cyber activity where a major incident has been identified.

'Email is dead. It's a thing of the past.' In the IT industry, this statement, or something like it, is said regularly — usually corresponding with the rise of a new communication or collaboration platform. Each time this happens, it's prudent to remember a general rule around tools: as long as they retain specific advantages for the human beings using them, they generally endure.

Networks form a critical core for our modern-day society and businesses. These networks are comprised of many types of components that make up the networks’ infrastructure. Network infrastructure devices can be physical or virtual and include things such as routers, switches, firewalls, and wireless access points.
