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 operatingsystem.
Fortinet has refreshed its branch office firewalls, adding power and features to its next-generation FortiGate G-series devices. FortiManager lets customers create and deploy security policies across multiple firewalls, simplifying administration in large, distributed enterprises, according to Fortinet.
Tighter integration between Fortinet's SASE and SD-WAN offerings is among the new features enabled by the latest version of the company's core operatingsystem. FortiOS version 7.4 also includes better automation across its Security Fabric environment, and improved management features.
Each EX4000 12-, 24-, and 48-port model also offers an additional 2 x 1GbE/10GbE SFP+ ports to support Virtual Chassis connections, which can be reconfigured for use as network ports, according to Juniper.All models support IEEE 802.3bz, which defines Ethernet speeds of 2.5GbE and 5GbE over twisted pair copper cabling.
Firewalls have come a long way from their humble beginnings of assessing network traffic based on appearance alone. Here are six predictions for the future of the firewall. Convergence also is happening in different formats; now security convergence is happening in appliances, virtual machines, cloud-delivered services, and containers. Convergence
FortiOS is the vendor’s operatingsystem for the FortiGate family of hardware and virtual components. FortiOS implements Fortinet Security Fabric and includes network security such as firewalling, access control, and authentication in addition to SD-WAN, switching, and wireless services. FortiOS 7.2,
“It allows users to navigate the filesystem, upload new files to the machine, as well as regular file operations like copying, moving and renaming files.” Firewalld is a commonly used Linux firewall service while notables provides filtering and classification of network packets.
Network slicing Network slicing can make efficient use of carriers’ wireless capacity to enable 5G virtual networks that exactly fit customer needs. It includes the operatingsystem, programming languages, database and other development tools.
First era of network security: The stateful firewall In the beginning, networking was created on the principle of trusting everyone and connecting everything as fast as possible. In the mid-1990s, the industry’s response was to create the stateful firewall, designed to control access to private networks.
To prove how dangerous it can be to use old and deprecated operatingsystems without any antivirus program, firewall or routers in 2024, YouTuber Eric Parker performed a proof-of-concept experiment by setting up a Windows XP virtual machine with an unsecured internet connection.
It can also encompass a constantly growing laundry list of additional features such as firewall as a service (FWaaS), browser isolation, sandboxing, data loss prevention (DLP), and web application firewall (WAF). Open Systems focuses on multinational small and medium-sized enterprises with 1,000 to 10,000 employees.
The SFN8722 OCP offers 10GbE performance, which is critical for today’s data centers where ultra scale dominates the market, supports 1000s virtual NICs and dual 10 GbE ports, and provides up to 30 million of packets per second and ultra-low latency under one microsecond. These include leading edge cloud service providers, Web 2.0
Server virtualization can do the trick for you if you also struggle to scale your applications to meet growing demands without breaking the bank. Server virtualization is a game-changing technology that has revolutionized the way organizations deploy and manage their IT infrastructure.
So, in a nutshell, least privilege says that every object in a system – whether a user, a process, or an application – must be able to access only the information and resources that it needs, and no more. It is essential to create standard, secure builds for your operatingsystems that eliminate unnecessary bloatware, plug-ins, and protocols.

Hardware based firewall – Filtering packets in both directions at a record rate of 250 nanoseconds, offering the fastest filter execution available on the market. Marty Meehan. These include leading edge cloud service providers, Web 2.0
While firewalls and other “perimeter” security defences remain critical for protecting and organisation and its assets, there has been a renewed focus placed on the importance of endpoint defences, because it is that individual’s vulnerability that is too often the easiest thing to exploit.
However, employees working outside the corporate firewall and other network protections pose some big security challenges, especially for large enterprises. CIOs and CSOs still have to ensure that employees outside of the corporate firewall can do their work securely. IT admins cannot secure assets that they can’t see.
When you place your resources in the cloud utilizing Microsoft as a provider of public cloud, your network which is situated in the cloud can be termed as a n Azure virtual network (Vnet). Your virtual network can be configured in a similar way as your internal on-premises network; i.e, You can select from various operatingsystems.
2] In this arena, desktop virtualization and cloud technologies will play starring roles. Notably, businesses are adopting virtual desktop infrastructure (VDI) as a way to keep data secure, teams collaborative, and staff productive while reducing costs. Additionally, VDI can reduce operational costs in two ways.
I try to keep the information linked to data center technologies like networking, storage, virtualization, and the like, but occasionally other items slip through. Ranga Maddipudi ( @vCloudNetSec on Twitter) has put together two blog posts on vCloud Networking and Security’s App Firewall ( part 1 and part 2 ). Virtualization.
Tom Nolle asks the question , “Is virtualization reality even more elusive than virtual reality?” This post by Ranga Maddipudi shows you how to use App Firewall in conjunction with VXLAN logical networks. I talked before about the difference between network virtualization and SDN, so no need to mention that again.
The second vulnerability (CVE-2023-1966) allows an attacker to execute code remotely at the operatingsystem level, potentially enabling them to change settings, configurations, software, or access sensitive data on the affected product. This vulnerability affects instruments with UCS v2.x x and has a CVSS v3 base score of 10.0,
VMI stands for Virtual Mobile Infrastructure and basically, it provides end users with a highly effective and an efficient way to have access to delicate mobile applications and information without much hassle. It creates virtual versions of mobile applications and sends them to a vast collection of devices.

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. For reasons that I won’t go into here (maybe later), I was recently pointed toward the vcluster project (for running virtual Kubernetes clusters in a namespace of an actual cluster).
OperatingSystems/Applications. I’m not sure if this falls into storage or virtualization, but we’ll place it here in the Storage section. Virtualization. It will be nice when the virtualization industry converges on some common set of disk formats for virtual machines. Want to install ESXi 5.5
The browser isolation technique considers non-whitelisted websites unreliable and isolates them from the local machine in a virtual environment. However, conventional solutions such as antivirus, firewalls, and other detection and blocking tools can only offer a limited level of security.
As the name clearly suggests, a vulnerability scanner scans systems and networks to identify and report back on open ports, active IP addresses and log-ons, software, OSs (OperatingSystems) etc. You could use them to scan servers, workstations, network devices, BYOD devices, virtual machines, databases etc.
