Firewall traffic analysis (FTA) is a network security operation that grants visibility into the data packets that travel through your network’s firewalls. Cybersecurity professionals conduct firewall traffic analysis as part of wider network traffic analysis (NTA) workflows. The traffic monitoring data they gain provides deep visibility into how attacks can penetrate your network and what kind of damage threat actors can do once they succeed.

Firewall monitoring is an important part of maintaining strict network security. Every firewall device has an important role to play protecting the network, and unexpected flaws or downtime can put the entire network at risk. Firewall monitoring solutions provide much-needed visibility into the status and behavior of your network firewall setup. They make the security of your IT infrastructure observable, enabling you to efficiently deploy resources towards managing and securing traffic flows.

The A10 Networks threat research team has investigated the HTTP/2 rapid reset vulnerability ( CVE-2023-44487), which has been identified in recent days and has advised customers on the best ways to mitigate it in their network.

The landscape of cyberthreats is continuously evolving, and to keep pace organizations employ robust network security strategies. This involves creating, executing, and maintaining a set of guidelines, or network security policies, on how the organization’s network should be protected from external threats. This process is termed network security policy management (NSPM) and it’s instrumental in maintaining the integrity of the network.

According to a recent Yerbo survey, 40% of IT professionals are at high risk of burnout. In fact, and perhaps even more alarming, 42% of them plan to quit their company in the next six months. And yet, according to Deloitte, 70% of professionals across all industries feel their employers are not doing enough to prevent or alleviate burnout. CIOs should take this statistic seriously.

Network segmentation or segregation is a network architecture practice used by network security personnel to divide an organization’s computer network into smaller subnets. Each subnet or network segment forms its own smaller network. By segmenting an organization’s network, personnel can better control the traffic flow between subnets, improve security policies, and make it more challenging for unauthorized users to access sensitive data and critical parts of the network.

Many enterprises have a variety of aspects that make up their networks, like Windows Defender Firewall, GPOs, and an AD infrastructure. Vulnerabilities in any part of the network can have a domino effect; once the first domino falls, the entire trail will go down with it, which can cause irrevocable damage to your network.

Cisco has released a Product Security Incident Response Team (PSIRT) advisory regarding a zero-day vulnerability in the web UI feature of Cisco IOS XE software. Cisco has stated that the web-based user interface should never be accessible through the public internet, yet research indicates that more than 10,000 Cisco devices have been exploited by an unknown threat actor. This critical vulnerability is being tracked as CVE-2023-20198 and is currently undergoing investigation for active exploitation.
