    Extending Enterprise Security with Mobile Security Services

    Mobile computing is well beyond a fad for e-mail enablement; enterprise organizations are undertaking mobile computing initiatives for new business processes and creative applications that reach employees, customers, and even business partners. When mobile devices were first implemented, CIOs turned to Mobile Device Management (MDM) platforms to onboard and manage devices, but MDM really doesn’t protect employees when they use mobile browsers or applications on the devices themselves. As mobile computing evolves, CISOs are implementing their own mobile security solutions for malware protection and application controls. Cloud-based mobile security solutions that integrate with traditional MDM are becoming popular choices for these requirements.

    Security Professionals to Washington: Less Talk, More Cybersecurity Action

    Since the term “cyber Pearl Harbor” was first coined during the Clinton administration, the U.S. government has warned about cybersecurity dangers but done little to protect the nation. Earlier this year, President Obama issued an executive order to address cybersecurity, but others in Washington view this as a political move and remain cynical about any real cybersecurity threat. Is the cyber threat real and if so, what should the U.S. Federal Government do about it?  To answer this question, ESG surveyed 315 security professionals working at U.S.-based enterprise organizations (i.e., 1,000 or more employees). This well-informed group of cybersecurity “insiders” is much more certain than DC pundits, think tanks, and legislators—they firmly believe that cybersecurity threats are real and want to see more from Washington in response.

    Addressing APTs and Modern Malware with Security Intelligence

    APTs first came on the scene in 2010, creating a wave of fear, hype, and activity. Many organizations increased their spending on information security and believed they were making progress, but ESG research indicates that nearly half of enterprise organizations are still regularly compromised by modern malware. While there is no single solution to this problem, CISOs can improve the efficacy of their threat defenses and security operations by integrating security intelligence into their security technologies and infrastructures. Webroot, a security intelligence leader, is partnering with a number of security device vendors to offer a strong combination of modern malware defenses and integrated security intelligence.

    Malware and the State of Enterprise Security

    The malware threat landscape is getting worse and many large organizations continue to suffer security breaches as a result. Why? Enterprises often lack the right security skills and their current defenses and security analytics are no match for increasingly sophisticated and stealthy targeted attacks. Fortunately, large organizations recognize these gaps and are increasing security budgets to bolster malware prevention, detection, and response. To benefit from these investments as soon as possible, CISOs should improve malware knowledge, invest in security analytics, and deploy modern anti-malware technologies on networks and hosts.

    Advanced Malware Detection and Prevention Trends

    The primary objective of this ESG research study was to survey security professionals working at enterprise organizations (i.e., 1,000 employees or more) in order to better understand their opinions, experiences, and skills as they pertain to modern malware. Furthermore, ESG wanted to understand how large organizations are preventing, detecting, and responding to malware attacks on a regular basis and what, if anything, is changing.
