Security is a major concern for IT admins and if you’re responsible for important workloads hosted in Azure, you need to know your security is as tight as possible. In this free webinar, presented by Thomas Maurer, Senior Cloud Advocate on the Microsoft Azure Engineering Team, and Microsoft MVP Andy Syrewicze, you will learn how to use Azure Security Center to ensure your cloud environment is fully protected.
There are certain topics in the IT administration world which are optional but security is not one of them. Ensuring your security knowledge is ahead of the curve is an absolute necessity and becoming increasingly important as we are all becoming exposed to more and more online threats every day. If you are responsible for important workloads hosted in Azure, this webinar is a must!

Cisco announced a major update to their CCNA, CCNP and CCIE certification program at Cisco Live last week, with the changes happening on the 24th February 2020.
The 10 current CCNA tracks (CCNA Routing and Switching, CCNA Cloud, CCNA Collaboration, CCNA Cyber Ops, CCNA Data Center, CCNA Industrial, CCNA Security, CCNA Service Provider, CCNA Wireless and CCNA Design) are being retired and replaced with a single ‘CCNA’ certification. The new CCNA exam combines most of the information on the current CCNA Routing and Switching with additional wireless, security and network automation content.
A new Cisco Certified DevNet Associate certification is also being released to satisfy the increasing demand in this area.
The current CCENT certification is being retired. There hasn’t been an official announcement from Cisco yet but rumours are saying that we might be seeing new ‘Foundations’ certifications which will focus on content from the retiring CCNA tracks.
Different technology tracks remain at the CCNP level. CCNP Routing and Switching, CCNP Design and CCNP Wireless are being consolidated into the new CCNP Enterprise, and CCNP Cloud is being retired. A new Cisco Certified DevNet Professional certification is also being released.
Only two exams will be required to achieve each CCNP certification – a Core and a Concentration exam. Being CCNA certified will no longer be a prerequisite for the CCNP certification.
If you pass any CCNP level exams before February 24 2020, you’ll receive badging for corresponding new exams and credit toward the new CCNP certification.

The format of the CCIE remains largely the same, with a written and lab exam required to achieve the certification. The CCNP Core exam will be used as the CCIE Written exam though, there will no longer be a separate written exam at the CCIE level. Automation and Network Programmability are being added to the exams for every track.
All certifications will be valid for 3 years under the new program so you will no longer need to recertify CCIE every 2 years.
If you’re currently studying for any Cisco certification the advice from Cisco is to keep going. If you pass before the cutover your certification will remain valid for 3 years from the date you certify. If you pass some but not all CCNP level exams before the change you can receive credit towards the new certifications.

In our previous article we explained how a Netflow Analyzer can help you gain visibility into your user traffic, application traffic and data flows while at the same time analyze traffic patterns, detect unusual traffic, verify bandwidth availability, detect Quality of Service (QoS) problems and a lot more.
In this article we will introduce Network Analyzer - a bandwidth and traffic analysis tool that helps you monitor the bandwidth utilization in your network and analyze the who, when, what of your network traffic. It uses flow technology to give you real time visibility into your network and supports all major flow formats such us netflow, sflow, jflow, IPFIX, and appflow.
Network Analyzer helps you to drill down into interface level details to discover traffic patterns and monitor device performance, recognize and classify Non-Standard Apps that hog your network bandwidth, and detect security threats. Using a network bandwidth monitoring tool like NetFlow Analyzer allows you to monitor all these critical parameters in real-time.
Here is what we'll be covering in this article:

Linux:
Note: During installation if you get an error message stating that the temp folder does not have enough space, try executing this command with the -is:tempdiroption parameter where is the absolute path of an existing directory:
./ManageEngine_NetFlowAnalyzer_xxxx.bin -is:tempdir
For non-x11 machines, use the following command:
./ManageEngine_NetFlowAnalyzer_xxxx.bin -console
Follow the instructions as they appear on the screen to install NetFlow Analyzer on to your machine successfully.
Once you have successfully installed NetFlow Analyzer, start the NetFlow Analyzer server by following the steps below.
Network security scanning is now possible on all versions of Acunetix Web Vulnerability Scanner, making this much easier and much more efficient to run both web security scans and network security scans at the same time. This is possible thanks to the seamless integration of Acunetix with the powerful OpenVAS security solution. There are many advantages of running network security scans in Acunetix - Click here to find out more.
Additional features supported by the latest version include:
For those interested, Acunetix is available as a free download.
Monitoring network traffic & bandwidth usage via Netflow is mandatory for any type and size network. Gaining visibility into user traffic, application traffic and data flows allows network engineers, administrators and security specialists detect bottlenecks – network congestion, unusual traffic patterns, monitor SLA agreements with providers, verify bandwidth availability, detect Quality of Service (QoS) issues, Wi-Fi Network monitoring, plus much more.
Here’s what we’ve got covered in this article:

Netflow is a network protocol developed by Cisco used to collect IP traffic information and monitoring network traffic. It’s used and supported in almost any network and has become the de-factor industry standard.
Other vendors support similar flow technologies, here are a few examples:
IT infrastructure has become much more sophisticated in the last decade and equally complicated. With the market growing every day, customer expectations are higher than ever. Networks are no more limited within a firewall. Now it extends to public and private clouds, and SaaS. This makes it more important for network admins to ensure faster connectivity between the user, and the public and private clouds or data centres.
The primary objective of bandwidth analysis is to monitor the performance of your network, and this can include different types of bandwidth utilization such as application traffic, wireless network, Wide Area Network (WAN) or Local Area Network (LAN) utilization, etc., where every device, service, and individual user is competing for their share of bandwidth. While the immediate solution for traffic congestion could be increasing your bandwidth capacity, the challenge is in realizing if your enterprise even requires that extra bandwidth. And in case you find yourself unable to provide sufficient bandwidth to users based on their needs or unable to control non-business traffic, you are not alone.
Network admins cannot manually keep track of everything going on in your network 24x7, and according to reports and surveys conducted by Packeteers, at least sixty to seventy percent of network managers don’t know what is traversing their networks. Your network is prone to various attacks, and congestions or spikes in your network could be caused by internal or external threats that can vary from DDoS attacks to your own business-critical applications.
As we can appreciate, it is extremely important the network tools used are capable of providing enough information and visibility so we can monitor, identify and troubleshoot effectively and efficiently as possible.
A common question is what capabilities should the bandwidth monitoring tool provide?
