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 […]

Orange Money deal with Airtel in West Africa part of expansion plan

Orange’s move to work with Airtel to offer mobile money transfer between the Ivory Coast and Burkina Faso is just one step in an effort to expand its services throughout Africa.Orange Money customers in the Ivory Coast can now send and receive money to or from Airtel customers in Burkina Faso. Orange Money has over 13 million customers in 12 African countries, including Jordan. The partnership with Airtel, which runs its Airtel Money service in 16 African countries, is likely to trigger more internetwork and mobile money transfers.In West Africa, Orange Money International Transfer already serves users in Senegal, Ivory Coast and Mali, but the pact with Airtel fills a gap in the region.To read this article in full or to leave a comment, please click here

Yahoo’s reported willingness to pay $11M for ‘insurance’ was the real March Madness

You may recall that last year around this time Yahoo, Warren Buffett and Quicken Loans teamed up to offer this challenge: If anyone could pick the winner of every single game in the NCAA’s 64-team, six-round March Madness basketball tournament, he or she would win a billion dollars.No one met the challenge, or came close. In fact, the tournament wasn’t even half over before the final perfect bracket sheet was no longer perfect. This came as no surprise to anyone, in large part because the odds against completing the challenge successfully were one in 9 quintillion or one in 128 billion, depending on who’s doing the math, according to this explanation in Slate.To read this article in full or to leave a comment, please click here

Remote port-mirroring in Junos

Information on remote port mirroring on Junos routers doesn’t seem to be very easy to come by for some reason – there is quite a lot of information about doing this on EX switches (a bit like RSPAN in Cisco’s IOS), which wasn’t what I needed.  Various other sources of information (such as Cluepon) say this can be done using a GRE tunnel, but that the capturing device needs to be a server that terminates the GRE tunnel – which all seemed a bit complicated.

I needed to remotely mirror a port on an MX to a second MX where a windows-based Wireshark was connected, so getting GRE working to a Windows host sounded like a non starter.

So I had to work it out myself – and hopefully this write-up will prove useful to someone else in the future.

An additional requirement for the customer was that the captured interface should be in a VRF, so the test-bed I set up below has production traffic flowing through a VRF, and the mirrored traffic in a GRE tunnel which is running in the global routing table.

Here’s the write-up I did for the customer:

Kenya becomes second country in East Africa to enjoy free Wi-Fi

Kenya has become the second country in East Africa after Rwanda to offer free Wi-Fi to the public, thanks to an initiative by Liquid Telecom and the Kenyan government.As in Rwanda, the free Wi-Fi connection will give users open access to the Internet with the exception of unlawful activities such as streaming or downloading offensive content or content that violates copyright.The move is expected to raise the demand for Wi-Fi-enabled handsets in the country. In Southern Africa, only South Africa so far is enjoying free access to public Wi-Fi, also provided by Liquid Telecom.In Kenya, Rwanda and South Africa, Liquid Telecom has put in place outdoor nodes designed to withstand harsh climatic conditions to offer uninterrupted connectivity and stable bandwidth.To read this article in full or to leave a comment, please click here
