From Barricades to Booths, Balancing Convenience and Security

Low tech can play an essential security role in protecting many critical infrastructure sites.

For example, the United States Department of the Interior’s Bureau of Reclamation uses swing beam barricades (Delta Scientific) to protect the nation’s water diversion, delivery, storage and hydroelectric generation projects. The bureau installed the anti-terrorist barricades at many of the nation’s best-known damns to close off one or two lanes of a roadway and provide counter terrorist level protection against vehicle attack. Crash tested, such barricades stop a 15,000-pound (66.7 kN) vehicle traveling 50 mph (80 kph) with zero penetration, equivalent to 1.2-million foot pounds of kinetic energy.

In another application, fifty custom-design bullet-resistant guard booths, K4-rated swing gates, barriers and bollards have been installed as part of the refurbishment of the San Ysidro (Calif.) Landed Port of Entry, the busiest land port in the world. Located between San Diego and Tijuana, the port processes an average of 50,000 northbound vehicles per day, the most of any landed port in the world. The majority of the traffic lanes will ultimately have two stacked bullet-resistant inspection booths for northbound traffic, effectively doubling the capacity of the 24 existing booths. The highly energy-efficient structures have a photovoltaic and Ethylene Tetrafluoroethylene (ETFE) roof structure that shades cars and officers. It also provides for rain and sun protection for the officers in booths. Because of its translucent nature, it allows for natural light thereby requiring no artificial lighting during the day.

Virtualization and Data Center Security: What You Need to Know for 2014

Data centers are increasingly becoming the center of the enterprise, and data center and cyber security is following the same path for security departments. According to Justin Flynn, a consultant at the Burwood Group, the virtualization of data centers allows enterprises to scale more easily and faster, with a smaller footprint.

However, hosting enterprise data in the cloud can make intrusion detection more difficult – how can enterprise security leaders team up with other departments to keep aware of cyber risks and traffic, and physical and data compliance during the virtual transition? How can CISOs and CSOs discuss cyber threats with the C-Suite to get the resources they need? And how can the proper infrastructure test and verify possible malicious attacks?
