Network Access Control – Network access control solution
Ready to get acquainted with the new generation of Network Access Control solutions?
In the modern threat map, retinal visibility of organizational endpoints is critical. Any device and device on the network can be a source of possible attack and therefore constitutes a landmark that needs to be identified, monitored and secured.
A modern NAC Network access control solution enables full visibility that significantly reduces cyber attacks.
Organizations today are facing an increasing level of cyber attacks and in particular of malware. The corporate network no longer sits within four secure walls; It extends to wherever users are located, as well as wherever the data moves.
Network access control is a fast growing market. In 2017, revenue grew 23.7% to $ 942.3 million. Analysts Frost and Sullivan report expecting an annual growth rate of 16.9% from 2017 to 2022.
The mobility, digitization and Internet of Things (IoT) are changing the way we live and work. The result is that communication networks are expanding and as a result, the complexity of resource management and the various security solutions is increasing. The high growth rate and size of the NAC market requires the development and implementation of a modern solution that will meet the needs of the modern network configuration. It is necessary to establish a leadership position in the Network access control market with a company that is able to think outside the box.
Network security with Network Access Control solution
Network access control (NAC Network access control) is a basic protection in network security. The basic premise of network access control is the security principle that end users / endpoints can be provided with policy-based access to various parts of the network and if there is an indication of danger (IOC) or exposure to vulnerabilities, blocking, closure or redirection will occur. However, enterprise networks have long since expanded beyond the “traditional” endpoints of servers, PCs, or virtual desktops (VDIs) and have evolved toward working with tablets, smartphones, and IoT and OT devices.
The IoT and BYOD (Bring your own device) trends are potential threat vectors that organizations need to deal with. According to analyst Frost & Sullivan by 2023 there will be 45.4 billion connected devices worldwide, most of them IoT devices. The rapid growth trend of IoT poses a serious challenge to enterprise networks as these often do not comply with the 802.1X standard.
Not only the number of devices but also the variety of operating systems and device types poses a challenge. Most IoT devices cannot implement an agent, so security-free security technology is required. As the quantity and variety of devices and operating systems increase, so does the organization’s ability to see and control devices and devices.
What does it take for organizations to overcome the challenge?
- Organizations need to develop visibility throughout the footprint of enterprise IT systems: campus, data center, private cloud, public cloud and OT networks.
- Other protocols in addition to 802.1X should also be supported.
Organizations face more and more challenges as IT and OT systems become unified. In the past, OT networks were isolated, but today they are undergoing rapid metamorphosis into IIoT (Industrial Internet of Things) and are no longer physically separated from IT networks. As a result, the threats move fluidly and freely between the cyber dimension and the physical dimension. Alongside this difficulty, there is the difficulty due to the fact that it is difficult to apply a patch to most of the OT devices.
Organizations are shifting workloads to the cloud, whether public, private or hybrid cloud and support is becoming necessary for platforms like AWS, Azure and other cloud computing platforms. Network administrators must deal with multiple device locations and access points.
The management of the corporate networks is usually decentralized because they are usually in a heterogeneous, multi-vendor environment.
The next generation of NAC solutions – Network access control
While Network access control is a powerful security tool, traditional NAC solutions have so far been based on very complex and difficult-to-implement technology. Unlike the previous generation of NAC, which was invasive and restrictive, NAC vendors today must focus on facilitating deployment and management and providing full visibility to all endpoints in the expanding networks of enterprise IT arrays.
Misconceptions about NAC solution
Next-generation features in NAC systems
The complexity of deployment and management of traditional network access control systems, combined with a severe shortage of professional and skilled security professionals, makes IT organizations need better security tools and automation systems to overcome limitations in the field.
The level of expertise required of a network engineer is very high and while organizations have invested in many and varied security technologies, improving the orchestration and integration of a variety of security solutions such as NGFW platforms, SIEM systems for managing security events or threat intelligence applications will naturally increase network access control efficiency. The investment in this type of platform.
It is best to stay away from inflexible policies of either authorizing or preventing
- A modern system based on flexible controls, based on the connection between users and devices and smart automation of the logical connections of the various network inputs
- To provide a high user experience and minimal disruption to the organization, the solution must integrate with other IT systems as well
- Smart automation and integration of other enterprise control systems reduces the vulnerability window by controls and operations
