    Popular media is filled with stories of computer hackers —young, male, nerdy college dropouts who are not very social—and their hacking activities.

    by John Linkous on December 26, 2014

    As we look forward to 2015, this is a good time to take stock of how the information security threats and attack landscape have been changing. Let’s see: major data breaches at global, brand-name organizations, state-sponsored hacking activity, revelations of our own government's attempts to access personal data. It would be easy to proclaim 2014 as the "Year of the Security Threat," but that's…

  • Network Intrusion: Methods of Attack

    by Robert Moskowitz on December 25, 2014

    A network intrusion is any unauthorized activity on a computer network. Detecting an intrusion depends on the defenders having a clear understanding of how attacks work.

  • Keeping the Lights On, Networks Safe

    by Fahmida Y. Rashid on December 1, 2014

    December is a month for looking back at all the things that happened this year and for looking ahead to what is in store next year. For many information security professionals, it is also a month of long hours as organizations rely on skeleton staff to defend the network. Criminals frequently launch their campaigns over holidays, weekends, and late at night when IT staff has a skeleton crew in…

    If SSL is the emperor’s new clothes, then Ivan Ristic in Bulletproof SSL and TLS has shown that perhaps the emperor isn't wearing anything at all. There is a perception that if a web site is SSL secured, then it’s indeed secure. Read a few pages in this important book, and the SSL = security myth is dispelled.
