Meltdown and Spectre

While many have already seen something on these two, this is the best set of articles I’ve found on these vulnerabilities and the ramifications.

Meltdown and Spectre exploit critical vulnerabilities in modern processors. These hardware bugs allow programs to steal data which is currently processed on the computer. While programs are typically not permitted to read data from other programs, a malicious program can exploit Meltdown and Spectre to get hold of secrets stored in the memory of other running programs. This might include your passwords stored in a password manager or browser, your personal photos, emails, instant messages and even business-critical documents. —meltdownattack.com

Windows, Linux, and macOS have all received security patches that significantly alter how the operating systems handle virtual memory in order to protect against a hitherto undisclosed flaw. This is more than a little notable; it’s been clear that Microsoft and the Linux kernel developers have been informed of some non-public security issue and have been rushing to fix it. But nobody knew quite what the problem was, leading to lots of speculation and experimentation based on pre-releases of the patches. —ARS Technica

You don’t have to worry if you patch. If you download the Continue reading

IoT: A vulnerable asset but also a recovery tool in disasters

If you think the proliferation of mobile devices changed the concept of the network edge, get ready for the emerging Internet of Things (IoT), where a network-connected sensor could be located on top of a mountain, in a corn field or even in the ocean.So, how does an enterprise incorporate IoT into its disaster recovery plan? In one sense, IoT creates a unique challenge because it is far-flung and vulnerable. But it can also become part of a DR solution, helping to protect the business in the event of a disaster, according to experts.+Also on Network World: REVIEW: 4 top disaster-recovery platforms compared; Review: Microsoft Azure IoT Suite+To read this article in full, please click here

Fortinet FortiGate-VMX and NSX use cases

Fortinet FortiGate-VMX NSX is an extensible platform; other vendors security solutions can be added to it by means of the Northbound REST API, and two private APIs: NETX for network introspection, and EPSEC for guest introspection. Fortinet’s FortiGate-VMX solution uses the NSX NETX API to provide advanced layer 4-7 services via service insertion, also called service chaining.  This enables... Read more →

Fortinet FortiGate-VMX and NSX use cases

NSX is an extensible platform; other vendors security solutions can be added to it by means of the Northbound REST API, and two private APIs: NETX for network introspection, and EPSEC for guest introspection.

Fortinet’s FortiGate-VMX solution uses the NSX NETX API to provide advanced layer 4-7 services via service insertion, also called service chaining.  This enables the additional inspection of VM traffic prior to that traffic reaching the vSwitch.  This enhances micro-segmentation where there is need for greater application recognition, anti-malware, and other Next Generation Firewall features.  The scale-out nature of NSX is maintained as NSX handles the instantiation of FortiGate service VMs on the hosts within the deployed cluster retaining its operational advantages, if the cluster grows additional FortiGate-VMX service machines will be created as needed.

 

 

One of the primary advantages to FortiGate-VMX is the availability of VDOMs for multi-tenancy in a service provider or enterprise environment – this enables segmenting traffic by organization, business group, or other construct in addition to application.  The segregation includes the administration, VDOMs are managed independently of one another, this can also be used to split the different security functions such as anti-virus, IPS, and application control into isolated units or only Continue reading

VMware AppDefense & CB Defense Demo

As you may have heard, VMware and Carbon Black have come together to deliver best-in-class security architected for today’s data centers.

In this demo, you’ll see an example of how CB Defense and VMware AppDefense combine to enforce known good application behavior and detect threats using industry leading detection and response technology.

For this demo, we’ll show how an advanced security breach can come in under the guise of an innocuous application (Powershell) and often go undetected.  We’ll walk through the steps that security teams can now take to respond and address the attack all in one application.

BrandPost: Deciphering the SD-WAN buzz and predictions

We were excited to participate in the November MEF 17 conference in Orlando, one of the industry’s most informative service provider events of the year. There is a lot of buzz and interest in managed SD-WAN services. It was a key focus area of MEF’s new SD-WAN initiatives and for this year’s conference agenda.Silver Peak Founder and CEO David Hughes delivered a CEO perspective: “SD-WAN From Software-Defined to Self-Driving.” David presented a vision for how SD-WAN technologies that leverage AI and automation can further accelerate the development of managed, customized SD-WAN services. David’s presentation also explored the future of SD-WAN and its impact on the broader software defined networking space.To read this article in full, please click here

SDN with Big Data Analytics for an Intelligent Network

Software, cloud computing and IOT are rapidly transforming networks in a way, and at a rate, never seen before. With software-as-a-service (SaaS) models, enterprises are moving more and more of their critical applications and data to public and hybrid clouds. Enterprise traffic, that never left the corporate network, is now shifting to the Internet, reaching out to different data centers across the globe. Streaming Video (Netflix, Youtube, Hulu, Amazon) accounts for an absurdly high percentage of traffic in the Internet and content providers have built out vast content distribution networks (CDNs) that overlay the Internet backbone. Higher resolutions (HD and UHD) will increase the traffic further, and by some accounts, will be over 80% of the total network traffic by 2020. More and more businesses are being created that reach their customers exclusively over the Internet (Spotify, Amazon, Safari, Zomato, etc). Real-time voice and video communications are moving to cloud-based delivery and network operators are challenged to deliver these services without impacting user quality of experience. And if this was’nt enough, with the advances being made in IOT, we have more devices than ever, lively communicating and chatting in real time over the Internet.

Security becomes a prime concern as Continue reading
