An informative article by Mr. Dinesh Malkani, President, Cisco India & SAARC. The Internet of Everything is the intelligent connection of people, processes, data and things. Citizens, companies and governments around the world are embracing it and turning to digitisation for more efficiency. Cisco believes digitisation of a country will depend on five key areas: visionary leadership, global open standards, smart regulation, public-private partnerships and a new ecosystem and India can play a powerful role in the Internet of Everything worldwide..... READ MORE

For those just starting your careers as new IT graduates, recent MBA’s, or others in the early season of your professional life, Mark Yolton, Vice President of Digital, Cisco Marketing, offers the following collection of thoughts as he reflects back on 30+ years, some of which you might find relevant & valuable....READ MORE

According to the Cisco Global Cloud Index, while today 73% of data is still mostly stored on PCs, by 2019 51%, or the major share of data storage, will shift to mobile devices, including phones, tablets and machine-to-machine (M2M) modules. As the amount of data inevitably escalates, the demand for cloud storage will rise. In fact, it won’t even take until 2019, as Cisco estimates that smartphone traffic will reach 201 exabytes a year by 2017, more than the 179 exabytes that can be stored on the phones, a major inducement to adding cloud storage.....READ MORE

Attackers Exploit Defensive Gaps: Adversaries are committed to continually refining or developing new techniques that evade detection and hide malicious activity. Security teams must adapt their approach to protecting the organization and users from increasingly sophisticated campaigns....READ MORE

As Cisco’s core product lines of routers and switches become more programmable through software, there may be an opportunity to deliver them through licensing or subscription arrangements as well, Robbins said....READ MORE

Instead of having one large layer 2 network, VLANs are used to segment a switch -- or network of switches -- into multiple, logical layer 2 networks. Broadcast messages sent and received are contained within each smaller VLAN. Thus, if you have a network of 1,000 end devices and create 4 VLANs of 250 devices each, each logical network must only have to deal with 250 devices of broadcast overhead, as opposed to all 1,000 if they were on the same layer 2 network...READ MORE

IOS XR is found primarily in Cisco’s high-end service-provider routers, including core routers, and Cisco claims it has more than 50,000 IOS XR devices running live in networks....READ MORE

Given that the video was TCP-based, I suspected packet loss. There was a WAN involved for some sites, and for the remaining remote sites there was shared LAN media in a fiber-driven loop path through daisy-chained sites (geography and cost-driven design)....READ MORE

Developing security awareness in staff, growing security professionals and equipping CIOs to monitor security remain vital components to a successful security management strategy. Annual training and computer based testing is a key part of our practice to equip our staff with the skills to detect and avoid phishing and similar information security threats....READ MORE

I had showed my topology in the above snap, As you can see I have a router that acts as the DHCP server and a Kali linux 2.0 machine which is connected to the same network. The same steps can be followed to hack a Windows or a Linux DHCP server also. This is how my router's DHCP binding looks before the attempt.... READ MORE

The quote "The more you know, the more you realize how much you don't know. The less you know, the more you think you know," is attributed to David T. Freeman. I discovered the truth of this as I began digging deeper. The trigger to this phase was when I realized that IPv6 was clearly not IPv4 with 128 bits. When did that happen? ....READ MORE

Enterprises will need to build out key pieces of their IT infrastructures to support a flood of devices, data, and decision-making tools. The following building blocks will help organizations get started on a path for successful IoT implementations......READ MORE

I recently came across a design in which GRE tunnels were built utilizing HSRP VIP addresses. At first I was unsure of how well this would work so as usual I decided to lab it up. It turns out that this is an excellent counter design to having to place metrics or do any type of fancy route manipulation to run a backup path.....READ MORE

OSPF will listen to neighbors and gather all link state data available to build a topology map of all available paths in its network and then save the information in its topology database, also known as its Link-State Database (LSDB). Using the information from its topology database. Then, it will calculate the best shortest path to each reachable subnet/network using an algorithm called Shortest Path First (SFP) ....READ MORE

This report takes research, insights and perspectives from Cisco and other security experts such as Level 3 Threat Research labs. Topics covered are Threat Intelligence IE trends in web attack vectors, web attack methods and vulnerabilities , Industry Insights IE how the industry is doing, Security capabilities Benchmark Study IE security professional’s perceptions of the state of security and Looking Forward, which covers some case studies and updates on on research targeting reducing time to detection of threats....READ MORE

Once OSPF is enabled on a router interface, a Link State Database (LSD) is established and all interfaces running OSPF are added to this table to be used in Link State Advertisements (LSAs), OSPF then the begins neighbor discovery and forming adjacency process. we’ll now take a closer look at both, neighbor discover and adjacency forming process....READ MORE

This HSRP election is based on a priority value (0 to 255) that is configured on each router in the group. By default, the priority is 100. The router with the highest priority value (255 is highest) becomes the active router for the group. If all router priorities are equal or set to the default value, the router with the highest IP address on the HSRP interface becomes the active router. In this post, we are going to make our Kali machine a HSRP participant and to become the active router by setting the highest priority to it. Yersinia tool (in built in Kali) helps us to perform this test with ease. For more information on HSRP, please refer RFC 2281 .....READ MORE

As more enterprises move toward digital transformation there is no better time than now to make sure your network is fit for the future. January is the month when health club memberships spike as people commit themselves to a healthier lifestyle. Why not take the opportunity to use the list below to ensure your own network’s fitness (without even leaving your desk)? ....READ MORE

One final question I put to the group was, “What is the one piece of advice you have for the CCNA-certified worker with just a few years of work experience?” The following list offers the top 10 pieces of advice that drew the most agreement and passion from this expert and experienced group.....READ MORE

First, attackers have become bolder and more coordinated. They’re sharing information. They’re moving and innovating very very rapidly. We’re watching the malicious actor teams embrace legitimate techniques like strong infrastructure and the use of virtual hosting—almost similar to IT teams that would be running any other business-critical service if it were legitimate. Now driven by financial gain, the attackers are looking for the most effective—and just like every other “business”—lowest-cost way to steal as much information as possible......READ MORE
