Network Security Visibility, Control and Response
Today’s organizations need more than a perimeter defense to secure their network. A comprehensive security solution should encompass the entire security lifecycle. There are three main building blocks of network security: Visibility, Control & Response. Each of these building blocks is crucial to support a full Security Automation & Orchestration solution that can shorten the time from threat detection to threat containment. The first step toward realizing an effective solution is complete endpoint and network visibility – discovering and identifying all the endpoints that may be vulnerable to attack as well as all networking infrastructure devices that enable network access.
As enterprises embrace the enhanced productivity gained from mobile devices, virtualization and cloud technologies, IT security teams face the evolving challenge of securing an increasingly complex and dynamic network.
Bradford Networks offers unparalleled network visibility into enterprise networks. Network Sentry enables organizations with complete endpoint and network visibility that can be leveraged in a variety of ways to enhance security via device profiling, network lockdown, and built-in analytics.
In summary, comprehensive endpoint and network visibility is the first step towards implementing a defensible security posture to protect an organization’s network. The next step towards the same goal is the ability to apply proper contextual information to implement various controls in accessing the network. Read about the second step in our Control section.
Network Sentry provides full control of every network connection to enforce regulatory compliance, implement dynamic network access control and enable scalable onboarding and guest management.
The second of the three crucial components for creating a complete Security Automation and Orchestration solution is the ability to control and enforce network access polices based on user, device, applications and network connections – essentially, the contextual information tied to an attempted network connection.
With the growth of Bring Your Own Device (BYOD) and the mobile workforce, the number of devices accessing corporate networks has increased substantially – creating a need for provisioning and onboarding large number of internal and external users on the network while keeping it safe from unwanted intrusions. At the same time, enterprises must now monitor and enforce network access policies with high volumes of traffic, enforce endpoint compliance and provide context to contain security breaches
Automated threat response shortens containment time & reduces costs Automated threat response is the third building block that is crucial for comprehensive Security Automation and Orchestration. Each of the three building blocks, Visibility, Control and Response, work in tandem to quickly contain malicious or suspicious access to your network.
With the large volume and sophistication of today’s cyber-threats, security teams must respond quickly to threats. Security and network teams need to collaborate to share information to effectively protect against threats – essentially bridging the gap between Security Operations Centers (SOC) and Network Operations Centers (NOC).
Automated threat response simplifies and streamlines your network security solution. Today’s organizations are benefiting from automated threat response that includes security events triage and correlation, ticketing systems integration and endpoint containment. In a recent Ponemon Institute study, participants averaged 17,000 weekly malware alerts, of which 19% were found to be reliable. Sadly, it also found that only 4% are investigated. [i] The Ponemon Institute further extrapolates that is costs the organization that participated in the study approximately $1.27 million a year in wasted time responding to security alerts.[ii] Clearly, automated threat response is crucial to lower these costs and effectively contain security threats.
Implementing these three steps will provide visibility into all devices accessing the network, contextual information tied to every network connection, and ability to automate threat response to shorten containment time.
