  • Cloud and mobility call for new network defense tactics

    As network attacks become more sophisticated, IT must equip itself with new network defense tactics. Continue Reading

  • Defending against the digital invasion

    As attackers move beyond “spray and pray” tactics to advanced persistent threats -- having better security than your competitors is no longer enough. Targeted attacks today are often for financial gain through extortion and threats to expose or delete sensitive data, and organizations need to make sure they’re prepared. We cover countermeasures to help organizations defend against evolving attack techniques and detect intrusions faster to minimize the damage. Johannes Ullrich, SANS Institute CTO and head of the Internet Storm Center, outlines the top emerging cyberthreats in 2015, from the Internet of Things and bring your own device to subtle data manipulations that influence business decisions and enterprise ransomware.

    Another big problem with security continues to be social engineering, which we also look at in this issue. Many organizations are moving beyond prevention to detection strategies, including automated breach detection and data-centric security measures. We also look at cybersecurity hiring strategies, employee development and ways to address geographical shortfalls. As some salaries skyrocket after a breach-laden 2014, is cybersecurity hiring in a state of crisis?

    Privacy Professor CEO Rebecca Herold shares her take on third-party security measures with Marcus Ranum. She offers solid advice on ways to hold contractors accountable. Finally, Editorial Director Robert Richardson looks at big data analytics as commercial tools, whose origins can be traced to NSA engineers, start to become available for large enterprises. Continue Reading

  • In denial about DDoS: Defense planning falls short

    Advanced distributed denial-of-service attackers are using a mix of techniques to hit targeted victims in ways all too similar to advanced persistent threats. DDoS defense planning is still lax at many enterprises, but if you do not have mitigation processes in place, it will cost you. Response, brand reputation and opportunity costs quickly add up in major attacks. The primary cost for victims, tied to the length of the outage, is revenue interruption says John Pescatore, director of emerging trends at the SANS Institute. The former Gartner analyst looks at the current denial-of-service landscape and associated costs in his article, “DDoS defense planning falls short.” Adam Rice and James Ringold continue their series on APTs. In their article “Man versus machine data,” the authors outline strategies to implement verbose logging across the enterprise and discuss the promise of big data security analytics to help security professionals track the APT lifecycle. The hard issues around intellectual property protection and the steps enterprises and vendors are taking to address them are also covered this month in Feature Editor Kathleen Richards’ article, “Breaches reignite intellectual property protection.” We also welcome back longtime columnist Marcus Ranum, who starts off the year chatting about metrics with IBM’s Diana Kelley. Security 7 winner Frederick P. Chang, Ph.D., offers his take on what is needed to take cybersecurity education and science to the next level. Continue Reading
