Enterprise networks are now more complex than ever. Cloud computing, connected devices, and highly mobile workforces put a ton of pressure on security teams to keep networks and data protected. At the same time, the tools and techniques used by cybercriminals to target enterprise data continue to evolve rapidly.

Network bandwidth requirements are doubling every 18 months owing to rapid growth of IoT devices, big data, virtualization, cloud storage, and SaaS applications. Network throughput is critical. Enterprises need security that keeps up with the pace of their business. The problem is compounded by the proliferation of point security products embedded across the distributed network. The tendency as networks become more complicated is to add new security devices to an already overburdened wiring closet.

Vendors are adapting to extend visibility and control over software-as-a-service (SaaS)-based services, which can be easily adopted by employees through their mobile devices to support file sharing and collaboration.

Rapid advances in analytics and machine learning are quickly changing the security landscape. Security managers having problems detecting malicious events should invest in security analytics to enable better threat detection and higher security staff productivity.

Network security analytics tools collect, process, correlate, and analyze meta data up and down the OSI stack in real time and for retroactive remediation over periods of time. These details are important when it comes to piecing together an entire sequence of events to determine what happened and when.

While network security analytics tend to scrutinize internal network data, many tools are also tightly integrated with threat intelligence to provide an outside-in perspective on network threats.

As enterprise security departments are asked to extend their protection capabilities to operational technology and the Internet of Things, new security models must emerge to provision and manage trust at scale.

The evolving enterprise network and its transition to a digital business model is one of the most challenging aspects of network security. As significant trends in computing and networking continue to drive changes across infrastructures, enterprises are looking for innovative network security solutions to embrace those changes.

Network monitoring is rapidly becoming a hot topic for enterprises because they cannot afford to lose access or control of the corporate network they rely on so heavily. But with the addition of new features and tools built around the Internet of Things (IoT), big data, and the cloud, ensuring network security is no easy feat for an IT department. A problem considering that network outages or slow performance - especially for critical functions such as credit card transactions, Internet access, email, and unified communications - can have a direct impact on the success of an organization.

And the larger the company, the greater is the network complexity. This brand of security hinges on visibility, which can uncover network blind spots. In essence, you cannot defend against what you cannot see and detect. But with visibility, it is simple to identify network hiccups and outages before they impact your business.

A strong visibility architecture requires four basic components to be effective - access to the network; monitoring middleware functionality; advanced monitoring functions; and connectivity of monitoring tools. A visibility architecture exposes the hidden locations where danger, problems, and inefficiencies may lurk, so you can address people, processes, and technology issues.

However, not all monitoring tools are created equal. Without a network packet broker, your monitoring tool may be getting overloaded with the wrong data, which reduces its efficiency and accuracy. A network monitoring tool is just the beginning of an effective visibility architecture.

Once implemented, one will see significant business, architectural, process, and technical improvements, for instance, the ability to deliver an enhanced user experience or greater visibility into both physical and virtual network traffic. It also ensures tools get all the data they need for true end-to-end visibility and insight as the network scales. Further, simplified management through easy integration with existing network management systems and programmatic controls offer automatic adjustments for dynamic issues and threats. Lastly, it helps leverage investments in existing monitoring and security tools, even while migrating the network to higher speeds.

The last step is to combine the visibility architecture with security architecture, creating network security resilience that resists attacks while supporting self-healing capabilities such as inline security tools, real-time responsiveness to security threats, SSL decryption, as well as application intelligence and filtering. The end goal is to get the right information to the right tool at the right time. This allows for access to deep insight into what is, and what is not, happening in the network.

Networks are currently undergoing dramatic change. Organizations are simultaneously wrestling with issues, such as BYOD, IoT, virtualization, SDN, cloud, the proliferation of applications, big data, and the expectations of the next generation of employees to blend their work and personal lives on a single device of their choosing, with instant access to any data, at any time, from any location. This has exponentially increased the attack surface that organizations need to be concerned with.

The response to increasingly complicated networked environments needs to be simplicity. Securing these evolving environments requires three things - collaborative intelligence, segmentation, and universal policy.

Fortinet has introduced its new security fabric architecture. It is designed to integrate security technologies for the endpoint, access layer, network, applications, data center, content, and cloud into a single collaborative security solution that can be orchestrated through a single management interface.

The Fortinet security fabric is designed to provide scalability, awareness, security, actionable intelligence, and open API strategy the organizations need to secure their evolving digital business. It enables the security, flexibility, performance, collaboration, adaptability, and manageability demanded across physical, virtual, and cloud environments, from IoT to the cloud.
