Deep packet inspection (DPI) refers to the method of examining the full content of data packets as they traverse a monitored network checkpoint. Whereas conventional forms of stateful packet inspection only evaluate packet header information, such as source IP address, destination IP address, and port number, deep packet inspection looks at fuller range of data and metadata associated with individual packets.
How does the fourth-largest network security company by revenue hold up against the first cybersecurity firm certified by the U.S. Department of Homeland Security? Fortinet's appliances and next generation firewalls (NGFW) have made it a category leader in unified threat management (UTM); let's see how they stack up against FireEye's comprehensive suite of enterprise security solutions.
Traditional firewalls have been around for decades. But NGFWs, uninhibited by the same technology limits, take advantage of significant advancements in storage space, memory, and processing speeds. The feature set for NGFWs build upon traditional firewall features by including critical security functions like intrusion prevention, VPN, and anti-virus, and even encrypted web traffic inspection to help prevent packets containing malicious content from entering the network.
If you think you’re having a bad day, you should see what happened to a group of Greek merchants crossing the Black Sea, 2,400 years ago. Providing a stark perspective on the vastness of history, their ship has just been discovered under 2km of water.
Many businesses that have allowed employees to continue working from home for the foreseeable future are aware that they need to update their cybersecurity. It’s likely that they have allocated some budget and IT resources to make those necessary changes. However, IT budgets are finite. Given the economic disruption of the pandemic, enterprises must strategically decide where to invest their cybersecurity budget most effectively.
When it comes to security, practitioners have to keep a lot they need to keep top of mind. The Open Systems Interconnection (OSI) model provides the fundamentals needed to organize both technical issues and threats within a networking stack. Although information security is shifting to a cloud-first world, the OSI model still continues to prove its relevance. We’ll cover four key reasons why the OSI model still matters and how you can operationalize it in today’s world.
Finding the right network security tools to secure your sensitive data can be a significant challenge for any organization. Choosing a firewall may seem like a simple task, but companies can get overwhelmed by the different firewall types and options. Making the distinction between a firewall and other security solutions can also pose challenges. Here are the answers to some of the most common firewall questions.
In previous blogs on the Netskope NewEdge network, we’ve discussed concepts including Secure Access Service Edge (SASE) architecture and why counting data centers alone is meaningless when trying to understand cloud service coverage. Now that we’ve laid the foundation it seems like a good time to get into what’s needed in terms of architecting the actual network and the connections required.
The old security model, which followed the “trust but verify” method, is broken. That model granted excessive implicit trust that attackers abused, putting the organization at risk from malicious internal actors and allowing unauthorized outsiders wide-reaching access once inside. The new model, Zero Trust networking, presents an approach where the default posture is to deny access.
