"The key to securing against this threat lies in a common metaphor-if a ship has a hole, it is better to patch the breach than bail the water Network World | Oct 21, 2016 4:00 AM P"

"Nmap is a great security scanner. Many systems and network administrators use it for tasks such as network inventory, managing service upgrade schedules, and monitoring host or service uptime. In this article, I'll guide you through how to use Nmap commands."

"In this article we will explain what TCP wrappers are and how to configure them to restrict access to network services running on a Linux server. Before we start, however, we must clarify that the use of TCP wrappers does not eliminate the need for a properly configured firewall."

"... By experimenting with pings and various levels of load on his Internet connection, he discovered that latencies were often four to 10 times larger than what should have been expected. He termed the phenomenon, "bufferbloat." His conclusion was that critical data packets were trapped in buffers that were excessively large. ..."

"Today we will walk through iptables and firewalld and we will learn about the history of these two along with installation & how we can configure these for our Linux distributions."

"Jul 4, 2016 09:33 GMT · By Marius Nestor · Share: Today, July 4, 2016, Ronald Henderson has announced the release of a new version of the Fedora-based Network Security Toolkit (NST) Linux distribution for network security analysis and monitoring."

"In this article we shall discuss about two powerful Linux utilities that are used for sharing file/folder to network computers that are scp and rsync"

"©2016 Chris Binnie On a continually changing network it is often difficult to spot issues due to the amount of noise generated by expected network traffic. Even when communications are seemingly quiet a packet sniffer will display screeds of noisy data. That data might be otherwise unseen broadcast traffic being sent to all hosts willing to listen and respond on a local network. Make no mistake, noise on a network link can cause all sorts of headaches because it can be impossible to identify trends quickly, especially if a host or the network itself is under attack. Packet sniffers will clearly display more traffic for the busiest connections which ultimately obscures the activities of less busy hosts."

"What Is Speed? Many non-technical people will say "I want to have a fast Web site." From a technical perspective, however, that's not a very useful statement, because it neither differentiates between the different types of speed, nor does it consider the multiple layers involved in a modern Web application, nor does it take into consideration multiple people and the crunch that comes from a sudden surge of interest in the site. "

"File transfer between Linux systems (and perhaps all POSIX systems in general) is in some ways a neglected subject. The arcane protocols in common use are far from secure, and the SSH replacements offer too much power and complexity. Servers holding highly sensitive data... "

"ONOS is building a better network The Open Network Operating System (ONOS) is a software defined networking (SDN) OS for service providers that has scalability, high availability, high performance and abstractions to make it easy to create apps and services. The platform is based on a solid architecture and has quickly matured to be feature rich and production ready. The community has grown to include over 50 partners and collaborators that contribute to all aspects of the project including interesting use cases such as CORD."

"The Internet is a big, scary place, and so we must protect our small business networks with strong, reliable firewalls. Firewalls can range from a simple gadget that keeps bad data packets out of networks to sophisticated multi-function gateways. "

"I came across Salt while searching for an alternative to Puppet. I like puppet, but I am falling in love with Salt :). This maybe a personal opinion but I found Salt easier to configure and get started with as compared to Puppet. Another reason I like Salt is that it let's you manage your server configurations from the command line, for example:"

"st, an independent IT-security institute, is well-known for testing Windows antivirus solutions, and the lab's findings are well respected, but this time AV-Test tested 16 Linux antivirus solutions to discover how well they did against Windows and Linux malware. "

"We know how administrators love free tools that make their life easier. Here are 20 of the best free tools for monitoring devices, services, ports or protocols and analyzing traffic on your network. Even if you may have heard of some of these tools before, we're sure you'll find a gem or two amongst this list - and if you know of any others, leave us a comment below!"
