Bare-metal switches poised to take off in data centers

Bare-metal switches that can be programmed like Linux servers aren’t just for big Web companies anymore. They may show up in a lot more average enterprises in the next few years.Cloud-based service providers like Facebook and Google have been building data-center networks out of generic hardware and homegrown software for years. Now vendors including HP and Dell are beginning to sell switches much like they do bare-metal servers. They may pre-load an operating system and provide ongoing support, but that OS is open and their customers will have much more freedom with this new kind of gear than they do with traditional switches from vendors like Cisco Systems.To read this article in full or to leave a comment, please click here

China discloses cyberwarfare unit, no one surprised

It came as a shock to just about no one in the cybersecurity industry that China has a cyberware unit, which was acknowledged by the government there this week.While the Chinese government has long denied attacking U.S. targets, U.S. businesses and government agencies have complained for years about attacks originating from China.The Chinese government noted the existence of the country’s cyberwarfare unit in “The Science of Military Strategy,” a publication put out by a research institute of the People’s Liberation Army, according to news reports this week. The U.S. military has acknowledged its own cyberwarfare capabilities for over a decade.To read this article in full or to leave a comment, please click here

Monetizing medical data is becoming the next revenue stream for hackers

The personal information found in health care records fetches hefty sums on underground markets, making any company that stores such data a very attractive target for attackers.“Hackers will go after anyone with health care information,” said John Pescatore, director of emerging security trends at the SANS Institute, adding that in recent years hackers have increasingly set their sights on EHRs (electronic health records).With medical data, “there’s a bunch of ways you can turn that into cash,” he said. For example, Social Security numbers and mailing addresses can be used to apply for credit cards or get around corporate antifraud measures.To read this article in full or to leave a comment, please click here

Routing on the CCIE Data Center Lab – How Deep Do We Need to Go?

Every time I teach NX-OS the same question often arises, “How good do we need to be at routing in order to pass the lab exam?” My first inkling is always to say ‘learn it all,’ but we all know that isn’t always possible. There is a ton of information to learn within the scope of this lab exam, so in order to fully understand this question, we need to look towards Cisco’s almighty guide, the blueprint!

They have gone pretty easy on us in terms of routing, but in their defense, they do have an entire lab dedicated to routing and switching. If we scan down the blueprint to Section 1.2, we see the category we are looking for:

While that comprises that entire section, I would also err on the side of caution and include Section 1.4a grouped within the L3 category, those being first-hop routing protocols such as HSRP, GLBP, and VRRP.

Look at what they ask us for here, and lets analyze it. They ask for BASIC EIGRP and OSPF, Bi-directional forwarding detection, and equal-cost multi-pathing. ECMP isn’t really its own ‘protocol’, rather something that most L3 protocols support. We will see that Continue reading

Net neutrality rules: Separating fact from hype

The net neutrality debate in the U.S. over the past year has been filled with hyperbole, speculation and questionable claims, coming from both sides of the debate.Let’s look at some of the hype and compare it to what we know from the U.S. Federal Communication Commission’s net neutrality order, released last week, and from other information.Four million people in favor of the rulesThere seems to be a misconception, driven as much by media coverage as actual statements by net neutrality advocates, that nearly all of the 4 million comments filed with the FCC in the proceeding were in favor of strong net neutrality rules. There’s some debate over analysis done on the final numbers, but we do know that a substantial number of comments came from people opposed to new rules.To read this article in full or to leave a comment, please click here

New attacks suggest leeway for patching Flash Player is shrinking

Cybercriminals are exploiting newly patched vulnerabilities faster, a sign that users and companies need to improve their software updating habits.Researchers from both Malwarebytes and FireEye reported Thursday that drive-by download attacks using the Nuclear Exploit Kit target a vulnerability that was patched last week in Flash Player.The flaw, which is tracked as CVE-2015-0336, was fixed by Adobe on March 12. It affects all Flash Player versions older than 17.0.0.134 on Windows and Mac, 11.2.202.451 on Linux and 13.0.0.277 ESR (extended support release).To read this article in full or to leave a comment, please click here

Wireless router from Huawei hints at new ways to speed up LTE

In the hunt for more spectrum to offer higher wireless broadband speeds, mobile operators and equipment vendors are showing a growing interest in a new candidate.Huawei Technologies has laid the groundwork for speeds up to 220Mbps using LTE-Advanced at 3.5GHz. On Friday, the company said it has launched the world’s first device, a wireless router, that combines the speedy network technology with that frequency band.The amount of spectrum is one of the things that determines what speeds a network can offer. The 3.5GHz band is an ideal candidate for offering high speeds because it has a lot of spectrum available, according to Huawei. What the vendor does not mention is that using the higher band also means worse coverage than what mobile operators can offer with current networks.To read this article in full or to leave a comment, please click here

Cisco NAT Cheat Sheet

I’ve always had a difficult time when attempting to remember how to implement the different types of NAT available on ASA and IOS devices. It doesn’t help that between the two device families, there are three different syntax versions used in the configurations. I created the PDF linked below as a quick reference sheet. It […]
