  • SSL Encryption: Keep Your Head in the Game
    Enterprises should establish security policies with regard to traffic inspection, and implement the right mix of SSL decryption and traffic inspection systems that don’t introduce latency or business disruption.
  • Out-of-Band TAPs Are an NSA Nightmare
    For the NSA, one of the hardest things to hack against is a network with out-of-band TAPs—which enable the continuous monitoring of network activity by sending copies of packets to security inspection and analytics devices.
  • Data Loss Prevention: Make It Work
    DLP provides a range of business benefits, including compliance support and intellectual property protection. The concept isn’t a new one, but the ability to put it to use in an easier, more viable manner is.
  • Security Challenges of SDN and Cloud: The Critical Role of Visibility
    Visibility into all inter-SDN traffic gives security and performance management technologies the best statistical chance of surfacing embedded malware and anomalous patterns.
  • To Improve Security Effectiveness, Look Inside
    While complex threats are an easy place to lay blame, lack of visibility is the real culprit. Turning your eyes inward to detect where compromises occurred sooner rather than later has the potential to limit your risks substantially.
  • Sometimes It's Hard To Get Rid Of An Old Flame
    On the whole, with only about 1000 machines infected today out of millions worldwide, the probability to exposure remains low, but just to be sure this old Flame doesn’t come knocking, there are precautions you can take as part of your security update regimes.
  • Security Automation: Is an 'Open' Mindset Your Best Path to Higher Security?
    How can you defend against a new generation of threats and attackers that are leveraging automation and outpacing alerting mechanisms and manual-access controls?
  • Firewalls for BYOD, Hacktivism and Today’s Highly Distributed "Network"
    IT managers aren’t the only ones aware of this BYOD trend – attackers are too. Whether their aim is to promote a cause (hacktivism) or turn a profit, our mobile devices constitute perhaps the easiest way to do so.
  • Enterprise Firewalls' Top Requirement: Scalability
    Second in a series on evaluating new firewalls. This week Johnnie explains how the highest security for your environment is to have technology that can sustain its protections through network growth and scale.
  • Firewall Wars 2.0 - Are You Armed?
    If you are ready to upgrade your firewalls you will have tons of choices but you’ll also need to conduct considerable research and gain an understanding of what those choices mean in terms of benefits and trade offs for your network.
  • Bewitched by 4G/LTE? Security Might Break That Spell
    4G/LTE networks are based on entirely new infrastructure. Naturally, 4G/LTE all IP infrastructure will extend the attack surface. While technologies like firewalls, intrusion detection sensors, encryption tools and subscriber protection suites can ameliorate some of the risks, the question now is: What’s available to you from your provider and for your chosen device?

  • What Makes for a Winning AV Strategy for Your VMs? What Choices Do You Have?
    We know by now that virtualized data centers and cloud deployments require more than the traditional physical security measures. To protect your data center, you must run antivirus scans on your virtual machines (VMs). It’s the right thing to do. It’s more so a question of how to do this right thing the right way.
  • How Vulnerable Are You to Cell Phone Hacks?
    Enterprises use smartphones and mobile devices in some manner to improve mobility and productivity, as do government agencies and even small-to-medium sized businesses. These organizations must protect their network and their users – and their devices, whether corporate owned or a user’s personal mobile device – from loss, theft and exploit.

    The private sector usually leads the way in technological advancement, but might we be witnessing a shift, where the government could begin to outpace the private sector? Has Vivek Kundra’s effort to reduce waste, improve efficiency, and save $18.8 billion through data center consolidation landed the U.S. Government on the cutting edge of technology?
  • PCI Security Standards Council Provides Further Guidance on Virtualization and the Cloud
    New guidance on virtualization from the PCI Council is here. So what if you’re a business readying to deploy a private cloud, where you’ll be storing cardholder data? Or what if you’re thinking of a move to a public cloud? What can you take from the new guidance?
  • What Does the Sony PlayStation Network Breach Teach Us about Cloud Security?
    When it comes to any security—though especially cloud security—there are several areas in which protections have to be applied. While we may not ever know exactly what happened at Sony, we can conclude that the right way to reduce the chances of such a breach happening again is to install as many layers of access protection and traffic visibility as possible.
