Making IP Video Cyber Secure

How financial institutions should be implementing video surveillance on their networks

Financial institutions have been historically slow to adopt IP video surveillance citing concerns about possibly compromising network security. But, in fact, there are steps institutions can take to harden network access through the camera so that the risk is no higher than any other devices attached to the company’s super information highway. Furthermore, the economic and operational advantages of going digital—from centralized storage to authorized real-time access through the cloud to remote diagnostics and remote maintenance—make a strong case for migration.

For the transition from analog to digital surveillance to go smoothly, however, corporate security officers need to work closely with their IT counterparts to better understand and align themselves with current network policies and standards. They need to convey bandwidth requirements for any new technology so that the network infrastructure can be designed to accommodate IP video traffic. And they need to work closely with manufacturers to understand the security features of the products they intend to install so that they can limit potential vulnerabilities to cyber threats.

Cyber Security: A Process Not a Product

Technology and features are important, but they won’t eliminate all risks or threats. According to a report issued by Trustwave Security, more than 90 percent of successful breaches are due to human error, poor configuration and poor maintenance, which is why it is so important to understand and rigorously adhere to corporate IT standards and policies when deploying any solution or device on the corporate network. This first line defense includes:

  • Strong password management:requires everyone to use strong or complex passwords with multiple characters, numbers and special symbols.
  • Common sense IT storage policies: restrict offloading sensitive files to unsecure locations like DropBox.
  • Timely patch downloads, consistent system upgrades and continuous virus protection updates.
  • Company-wide security education: embraces a security culture that teaches users to be more cautious and automatically report suspicious behavior.

With active cyber threat analysis, corporate security officers can identify potential risks and determine what steps should be taken for protection. Whether opportunistic or a targeted attack, it’s impossible to eliminate all risks. So it’s imperative to identify the institution’s “critical assets” and take aggressive measures to make their protection a priority.

While corporate policies and procedures for cyber security are all well and good, without someone to take ownership of their implementation they’re just empty words. It would be like putting a lock on the door and then leaving the key in it. Furthermore, instituting cyber security measures isn’t a one-and-done task. Systems need to be constantly audited to ensure everyone continues to adhere to cyber security measures and that those measures adapt to changing threats and risks. Risk and threat assessments need to be the standard and not an exception. In an environment that’s constantly changing, these processes need to be evaluated on a regular basis to ensure new potential threats have not emerged.

Video Cyber Security: Part of an Integrated Protection Strategy

Network cameras don’t determine the level of security on an institution’s network. They integrate into the security settings already in place. Therefore a corporate security officer should consider a number of factors when choosing an IP camera.

  • Security is a priority: The manufacturer should have a reputation for providing cameras with minimal exploitable flaws. The firmware and interfaces need to be robust and resilient. All components should be quality assurance validated. And the manufacturer should be keeping abreast of cybersecurity trends and updating their products in response.
  • Built on a standard platform: The camera and features should easily align with the organization’s infrastructure and IT policies. The platform kernel and services should be constantly monitored and updated when vulnerabilities and flaws come to light.
  • Ongoing support: The manufacturer/ integrator should provide assistance in configuring, managing and maintaining the camera for optimal benefit. As corporate security dives deeper into camera features and capabilities they should examine how they can be used to harden network protection. For instance, out of the box cameras come with default passwords and default settings. If left as is, they would certainly provide an exploitable path to the network.

As a standard level of protection, corporate security should review and establish configuration standards that should be implemented. This would include changing those defaults to strong passwords and implementing customized network settings for their specific network environment. They should also set the date and time parameters to establish an audit trail for any setting changes. Some of the other hardening measures network cameras should support include.

  • HTTPS encryption for network traffic
  • 802.1X protection against port hijacking.
  • Unique VMS/client account credentials.
  • Backup admin account credentials.
  • Disabling services that aren’t being used to prevent malware insertion
  • An IP address filter to precisely define what IP traffic can be received and sent by the router.
  • A remote syslog for auditing purposes
  • Certificates of authority for managing and authenticating permissions to access video .
  • Advanced compression algorithms like H.264, H.265 and Zipstream to minimize bandwidth consumption and storage.
  • Edge storage encryption for installations where recorded video needs to reside incamera for an extended length of time.
  • In the not-too-distant future, we’ll likely see IP cameras integrating with other common network security features such as: Active Directory for authenticating and authorizing who can access, install or update network camera settings.
  • Lightweight Directory Access Protocol (LDAP) for accessing and maintaining distributed director information services over the IP network. network[WU1].

Creating a Cyber Secure Ecosystem

A cyber secure ecosystems relies on the coordinated efforts of physical security and IT. If corporate security managers adhere to IT guidelines and best security practices when implementing their IP video surveillance system their solution won’t introduce any more vulnerability to the institution’s network than any other device attached to the backbone.

Bringing surveillance into the digital age provides significant advantages to both corporate security and the organization as a whole. First is the adoption of a technology based on open standards that can create greater long term value. In an analog technology world, video systems and sites usually operate as independent silos which require extra manpower to manage and retrieve information. These proprietary systems have limited scalability and don’t easily integrate across locations or with other security technologies such as fire detection and access control. As a result, unlike IP-based systems, their investment value tends to diminish as the institution grows and expands its portfolio of security tools.

With IP video, corporate security becomes a seamless part of the institution’s digital world and can be more agile and responsive to threats. IP video provides a security solution that easily scales and adapts as the business grows and the landscape of cyber threats continues to evolve.
