Networking models help us understand the ‘lay of the land’ when it comes to protecting the network. In our journey through the Open Systems Interconnection (OSI) framework, we’ve arrived at the last stop in the media group, the OSI network layer. Remember, we’ve gotten here via the OSI data link layer, or the ‘how’ the ze

Peek inside any enterprise security operations center (SOC) today, and you’ll likely see a crowded and high-pressure cybersecurity ecosystem. Over the past few years, as technology evolved rapidly, attackers have developed a growing array of strategies and tactics. In response, security organizations have deployed more and more tools and point solutio

What is a Personal Firewall? May 9th, 2021 No Comments Data Privacy, Data Protection, Firewall, Network Security, Online Privacy, Online Safety, PC security Firewalls are a term many know as protective of their computers from cyberattacks, but not m

Older perimeter-based firewalls aren’t up to the task of safeguarding today’s more distributed networks. But that doesn’t mean the end of the firewall is in sight. On the contrary, businesses and other groups are turning to next-generation firewalls (NGFWs) hosted in the cloud to fulfill their evolving security needs. These ‘virtual&

Is a firewall a thing of the past? People have been questioning the utility of firewalls for years. Columnist and editor Roger A. Grimes wrote that “firewalls need to go away” in May 2012. Grimes reasoned this was because firewalls “have always been problematic, and today there is almost no reason to have one.” Is Grimes right? Is th

pfSense is a very popular free and open source firewall solution. It does not only provide classic firewall services but has plenty of features like VPN server or can offer DNS, DHCP, proxy services… and many more. pfSense is also proposed by some companies as a commercial service with support. That’s why it is used in many organisations. Abo

Firewalls have become a standard aspect of internet security. There’s one built into your home WiFi router for instance, and your computer may use one too. But how did a relatively boring technology get such a cool name? Why is it called a firewall? A name stolen from the construction industry Firewalls have existed for many years, long before the Internet b

Dealing with the aftermath of ransomware attacks is like Russian roulette. Submitting the ransom might seem like it’s the sole option for recovering locked data. But paying the ransom doesn’t mean that your organization will get its affected data back.Let’s not forget that ransomware also continues to evolve as a threat category. Beginning in late November 2

Cisco addresses a critical remote code execution (RCE), authentication bypass, and static default credential flaws that could lead to full router takeover. Cisco has released security updates to address critical remote code execution (RCE), authentication bypass, and static default credential vulnerabilities affecting multiple router and firewall devices.

U.S. Cyber Command believes foreign APTs will likely attempt to exploit the recently addressed flaw in Palo Alto Networks’s PAN-OS firewall OS. Recently Palo Alto Network addressed a critical vulnerability, tracked as CVE-2020-2021, affecting the PAN-OS operating system that powers its next-generation firewall. The flaw could allow unauthenticated n

Palo Alto Networks addressed a critical flaw in the PAN-OS of its next-generation firewalls that could allow attackers to bypass authentication. Palo Alto Networks addressed a critical vulnerability, tracked as CVE-2020-2021, in the operating system (PAN‑OS) that powers its next-generation firewalls that could allow unauthenticated network-based attackers

After 20 years of prominence, distributed denial-of-service (DDoS) attacks may be causing more devastating effects than ever. The first DDoS attack occurred way back on July 22, 1999 when a network of 114 computers infected with a malicious script called Trin00 attacked a computer at the University of Minnesota, according to MIT Technology Review. The infect

The two programming languages, Java and Python, are affected by serious FTP Injection flaws that can be exploited by hackers to bypass any firewall. Attackers can trick Java and Python applications to execute rogue FTP commands that would open ports in firewalls The unpatched flaws reside in the way the two programming languages handle File Transfer Protocol

As we approach Thanksgiving in the U.S., the one thing I look forward to the most — aside from turkey and spending time with my family — is football. As I watch the games, the security geek in me can’t help but notice some parallels between football and network security, particularly firewalls and intrusion prevention.
