    The threat landscape is an ever evolving environment that must be addressed with constant iteration. Since the Cisco Intrusion Prevention System signature configuration has grown over the past few years, the Cisco Security Research and Operations IPS Signature Development Team performed an exhaustive review of the default IPS signature settings currently shipping. As a result of that analysis, the team will be releasing changes to the default signature set via signature updates in a two-phase process over the course of several months.

  • Online Shopping: A Classic Case of Convenience vs Security

    Andrae Middleton
    21 Dec 2011 | 12:28 pm
    It is certainly a new day and age for many aspects of today’s society. One prominent sector that continues to lead by example in this area is the Internet, more specifically the online shopping environment. Note that online shopping is not a simple matter of go to a website, click “buy,” and checkout. That would be too simple. Ironically the purchase aspect itself tends to be the simplest matter here. The crux of the experience begins with the search and research phase. What exactly does one need/want? Is there a particular brand in mind? Is there a popular alternative? The convenience…

  • Taking Part – What Being a Part of L2012 Means for Cisco

    Ian Symes
    27 Jan 2012 | 2:30 pm
    In less than 200 days, the greatest show on earth comes to my country’s capital, London. It’s never happened before in my lifetime and in spite of longer life expectancies, it is probably never going to happen again. Which means not only do I want to savour every moment, share it with my family and friends but I also want to leave a permanent mark in terms of Cisco’s involvement. As a marketer, sponsoring a global event such as London 2012 is incredibly exciting and at the same time a major challenge. With so many other sponsors and the general media noise that builds up around the…

  • The Right ‘Rights’ – Lessons from the Cisco London 2012 Olympics Sponsorship

    Pippa Collett
    9 Jan 2012 | 5:32 pm
    Correctly conceived and creatively executed sponsorship is a powerful marketing tool. Why else would the Fortune 500, along with millions of other businesses big and small, invest precious marketing dollars in the discipline? As mentioned in my previous blog post, the first step in successful sponsorship is having clear objectives, whether those are aimed at brand building, commercial gain or stakeholder engagement. Clearly articulated SMART objectives are a pre-requisite for achieving the second most important aspect of successful sponsorship – securing the right ‘rights’.

  • Google Places is the Place for You

    Ruth White-Cabbell
    2 Dec 2011 | 12:07 pm
    You probably already have a Google Places listing and don’t even know it. Google collects data from multiple sources, some of which may be outdated or incorrect and aggregates these into a Places listing. As an experiment, I checked Google Places listings for several Cisco partners and found that only one out of the 10 listings I checked had been claimed and verified by the partner company. Most had outdated or irrelevant information. Find out why Google Places is important for your business.

  • Sponsorship – Past Its ‘Sell By’ Date?

    Pippa Collett
    6 Oct 2011 | 8:00 am
    In the good old days last century, global sponsorship was the preserve of a select number of companies. Only a handful of sponsorship properties could be considered to have global reach (The Olympic Games, FIFA World Cup, Formula One Racing). A similarly small number of brands were big enough to pay the premium for gaining mass market brand exposure at a fraction of the cost of a global advertising campaign. But technology has changed all that. Exponential growth in computing power, the internet and mobile has created a new environment. Brands are now able to reach customers with individual…

  • Seven Important Takeaways from the 2011 MarketingSherpa B2B Summit

    Ruth White-Cabbell
    4 Oct 2011 | 8:00 am
    The biggest challenges for B2B marketers are 1) generating high-quality sales leads, 2) providing a sufficient volume of leads to sales, and 3) accommodating lengthening sales cycles. No real surprise there. I’m sure all of us experience these challenges. What is surprising is that B2B marketers don’t appear to be adapting new marketing practices that can help to address these challenges.

  • Moving Beyond the Internet of Things in 2012

    25 Jan 2012 | 6:52 pm
    Imagine a world where billions of objects have sensors to detect,  measure, and assess their status, all interconnected over public or  private IP (Internet Protocol) networks. This world of interconnected  objects will have its data regularly collected, analyzed and used to  initiate action, providing a wealth of intelligence for planning,  management, policy and decision-making. Key information will be pushed  out from machines to other machines, to individuals, and to public and  private organizations, allowing them to take action appropriately.

  • Loading an IOS on a switch via Xmodem

    24 Jan 2012 | 8:36 am
    A very good evening to all! There are times when the IOS on a switch may crash and (as a last resort) you need to use the painfully slow Xmodem transfer to save your life. I bought a 3550 a while back and that is precisely what happened with me. Without much else to try, I decided to give Xmodem a shot. I want to share how this can be used and I hope that this may be useful to others. Since the device is in ROMMON, there’s not much that you can do.  There is, however, a method to transfer another IOS using a direct  console connection with a PC (the transfer is over…

  • RE: Top 10 Cisco Wireless “Good to Know”

    27 Jan 2012 | 4:24 pm
    Jeff,     you may want to add what else the dynamic-interface IP comes to play for.  The IP address is checked when you do an intercontroller roam, so that the WLC knows if you did a L2 or L3 roam, and whether to anchor your traffic or to pass the MSCB entry to the new WLC.
