Admins with firewalls from Palo Alto Networks should make sure the devices are fully patched and the management interface blocked from open internet access after the discovery this week of a zero-day login authentication bypass in the PAN-OS operating system. Palo Alto Networks published its advisory the same day.
The various agencies have each approached the challenge of securing the network edge from a different angle, releasing their reports on Tuesday. Foreign adversaries routinely exploit software vulnerabilities in network edge devices to infiltrate critical infrastructure networks and systems.
For example, Palo Alto Networks has integrated PQC into its VPNs and next-generation firewalls to protect data in transit against quantum threats. Ensure quantum-ready hardware: Require that new infrastructure device purchases, such as routers and firewalls, have quantum-resistant or upgradable firmware.
From customers to experts to standards bodies, a consensus is building that says continuous monitoring will vastly improve the security of our networks and critical infrastructure. A typical enterprise can collect logs and events from firewalls, routers, servers, PCs, and more. So what is it?!
We’ve migrated to a userid-password society; as we’ve added layers of security, we password-protect each layer: PC (and now device), network, enclave, application, database, and storage (encryption). Over time, our use of devices and network resources will form a pattern; no two people should have the same behavioral patterns.
In our organization, we tend to isolate IoMT devices from the rest of the network. We only allow IoMT devices onto our network when they pass through our firewall. We’ve built our cybersecurity framework according to NIST and CIS guidelines, which serve us well in meeting regulatory compliance requirements.
Versa Networks has classified this as a privilege elevation flaw, as it was primarily used to harvest credentials from users logging into the system. Versa Networks has responded to the threat by: Releasing patches for affected versions of Versa Director; Advising customers to upgrade to version 22.1.4 and 22.1.3.
The rise of personal gadgets, the shift towards remote work, the BYOD trend , and advances in AI have all contributed to home networks becoming an extension of companies' cyber defense perimeters. However, many end-users do not recognize their home networks as extensions of their company's security boundaries.
Every organization follows some coding practices and guidelines. Non-curated solutions The most challenging but lucrative feature of a SAST can be to evolve as per the patterns of an organization’s code. Also, most of them have a set of secrets, variables and redundant strings in the code. This is where AI is going to create an impact.
If malware is detected on workplace computers, these devices must be promptly disconnected from the network to prevent further spread. This includes physically unplugging Ethernet cables and disabling Wi-Fi and Bluetooth connections to ensure complete network isolation. Introduce MFA for all corporate accounts.
Users’ firewalls configuration and intentional or unintentional throttling of bandwidth. UDP and TCP transport protocols are the most common means of data transfer across networks. Bandwidth, as we’ve just discussed, determines how much data the network can send or receive, and is beyond our control. Users’ internet quality.
As CIOs we spend a great deal of our time attempting to secure the company’s networks from the bad guys because we understand the importance of information technology. This activity takes on a whole host of different forms: firewalls, end user training, security sweeps, etc. Image Credit: Carl Jones. What Do The Rules Say?
Well, let’s see…stuff on Envoy, network automation, network designs, M1 chips (and potential open source variants!), Networking. Ivan Pepelnjak shares some links and thoughts on configuring the NSX-T firewall with a CI/CD pipeline built on GitHub Actions and Terraform Cloud. Servers/Hardware.
We use templates for network devices, workstations, laptops, and servers so that all of our devices match our security templates. Network Device Configurations. For network devices, we should consider using RADIUS/TACACS+ for authentication purposes, not a shared user account. How do we do this kind of monitoring?
The challenge: How are you going to secure your network when it has expanded to remote employees? Countless organizations made tough decisions regarding their networks, and what we’ve seen is that getting a remote workforce connected quickly took precedence over getting them connected securely. How to address this challenge.
Networking. Tor Anderson has an article on using IPv6 for network boot using UEFI and iPXE. has a great blog series going called “Hey, I can DevOps my Network too!” We all know that security is more than just a host-based firewall, but a host-based firewall can be part of an overall security strategy.

If your organization handles either of these sensitive data types, you must follow guidelines to keep your systems secure. While their requirements differ slightly—and may change annually—both PCI DSS and HIPAA require organizations to build and maintain a secure network and systems using the following security measures: System auditing.
This includes monitoring network traffic, logs, and endpoints for suspicious activity, as well as implementing intrusion detection and prevention systems. An MSSP collects and analyzes security-related data from various sources, including network logs, endpoint logs, and other security tools. What is SOC 2?
White hat hackers, also known as ethical hackers or security researchers, are individuals who use their computer programming and networking skills to help organizations protect themselves from cyber threats. These individuals are often highly skilled and have a deep understanding of computer systems, networks, and cybersecurity principles.
Moreover, compromised IoT devices can be used to launch large-scale attacks on other devices or networks, creating a ripple effect that can cause significant damage. Malware: Malware can be introduced into IoT devices, which can then spread to other devices on the same network, causing widespread damage.
But conversely, trying to prohibit the use of and blocking of AI at the firewall would be akin to being considered a Luddite from the Stone Age – you simply cannot prevent access to AI and be a player in the 21 st century. And that’s why in October, the White House issued its guidelines on regulating AI in government agencies.
Networking. Tyler Christiansen recently published a post on a network automation workflow that was based on a presentation he gave at the SF Network Automation meetup. This article by Russell Bryant is a great overview and update of the work going on with Open Virtual Network (OVN). Cloud Computing/Cloud Management.
Yesterday we talked about the audio-only social network Clubhouse , which found itself at the center of controversy after failing to take action or even make a public comment after users began to experience harassment within the app. Of course, it’s easy to laugh at some of the puritanical content guidelines TikTok has established.
Facebook bans a violent Boogaloo network. It was just a few days ago that I wrote this column about how the Boogaloo movement — a loose-knit collection of anti-government types, some of whom are agitating for a second civil war — had hijacked social networks to spread. for 5G networks. It also raised a fresh $100 million.
The most intense app bans happen at the network level, blocking any communication between the targeted servers and users in the country. That’s the approach taken by China’s Great Firewall, and it’s how India enforces its recently implemented TikTok ban. TikTok doesn’t have the same vulnerabilities as Huawei or ZTE.
