How embarrassing! It turns out there was a security hole lurking in Linux's netfilter firewall program.
Learn about some of the best-known open-source firewalls based on Linux to protect networks and computers from cyber security threats.
IPFire 2.27 Core Update 161 has been released as a new maintenance update to the hardened open-source GNU/Linux distro that primarily performs as a router and a firewall. The release brings exFAT support to IPFire and boosts the intrusion prevention system's performance.
Generating much excitement back in 2018 was bpfilter for the potential to better Linux's firewall and packet filtering by making it more robust and performance. Recently work on this BPF-based firewall solution was renewed and the performance potential over iptables and nftables is looking very good for the future with more feature work planned around new matches and targets, containers integration, in-place upgrades support, privilege separation, and BPF code optimization support.
The tiny ATtiny85 chip doesn’t look like the next big cyberthreat facing the world, but sneaking one on to a firewall motherboard would be bad news for security were it to happen. Learn more in an interesting Naked Security article:
Raluca Ada Popa found a fix for one of cybersecurity’s most fundamental challenges: securing computer systems without employing firewalls to keep hackers out.
DNS protection could prevent approximately one-third of the total losses due to cybercrime – which translates into billions of dollars potentially saved.
Security researchers have uncovered a swathe of serious vulnerabilities in a firewall system developed by CUJO which has been designed to prevent cyberattackers from infiltrating home networks.
A firewall is a set of rules. When a data packet moves into or out of a protected network space, its contents (in particular, information about its origin, target, and the protocol it plans to use) are tested against the firewall rules to see if it should be allowed through.
It will take a dramatic reimagining of security to dedicate focus to the areas where company data actually resides. It starts with tearing down the firewall.
On April 21, Michael Tremer announced that a new maintenance release for IPFire, a Linux distribution that can be used by beginning and experienced system administrators alike to deploy a firewall, proxy server, or VPN gateway on their infrastructure without too much hassle, is available for download.
Late last year, CSO Online reported on a vulnerability in Drupal that could have left thousands of websites compromised. Last week, researchers examined the attack in more detail, measuring the time it would take to compromise a website completely.
Phil Cummings says network firewalls will continue to be a critical piece of Health Information Technology Services -- Nova Scotia security portfolio for one simple reason: nothing's come along to replace them.
Once, firewalls were useful for certain types of attacks. Now they're more trouble than they're worth -- and create a false sense of security into the bargain
Sourcefire is moving into the firewall business, bringing its experience in intrusion prevention systems (IPS) such as Snort to offer a more context-aware platform that can better adapt to modern security threats than traditional firewalls, according to the firm.
It's no doubt that one of the leaders for network equipment is Cisco Systems. Newer Cisco devices are starting to use what Cisco calls its "IOS-XE" operating system, which is a customized flavor of GNU/Linux. Yes, GNU/Linux, which should not come as any surprise as GNU/Linux is used on countless high level appliances and security devices.
The IPFire project development team has announced the first beta release of an ARM port of version 2.11 of its open source firewall. IPFire is a Linux server distribution that can be booted from a CD or USB drive, or installed to a computer's internal drive.
Fwbuilder is a unique graphical firewall tool that allows the user to create objects and then drag and drop those objects into firewalls, to build a powerful security system for a single PC or a network of PCs. Fwbuilder supports a wide range of firewalls (Cisco ASA/PIX, Linux iptables, FreeBSD's ipfilter, OpenBSD's pf, and more), so its rules can be deployed on multiple platforms.
Some of the most commonly-used firewalls are subject to a hacker exploit that lets an attacker trick a firewall and get into an internal network as a trusted IP connection.
Traditional firewalls might not be enough, argues Palo Alto Networks founder Nir Zuk. The world is very different from the days when email ruled the roost and Yahoo, not Google, was the first search engine name that rolled off your tongue.
