Software-defined security (SDS) is a security model in which specialized software controls and manages information security in a computing environment. In software-managed, policy-driven, and governed security, most critical security controls, secure remote access are automated and monitored by software, such as intrusion detection, network segmentation, and access control.
According to the market database, Software-defined security typically finds applications in IT environments with minimal or no hardware-based security dependency, such as cloud computing and virtualization environments. Each new device created within the environment is automatically covered and controlled by the base security policy. Additionally, this ensures that the security reach and scalability of the underlying environment can grow with the infrastructure/environment resources. A software-defined and managed security environment can also be moved or migrated between other data centers/IT facilities without affecting the security policy and controls implemented.
A key concern is how to implement and introduce advanced security mechanisms to protect their assets and networks. An organization’s security approach today entails identifying the potential threat such as a Distributed Denial-of-Service (DDoS) or malware attack. It then calculates the likelihood of the threat and its impact on the company and subsequently implements some control mechanisms that can detect the attack and mitigate it when it occurs.
A Software-Defined Networking (SDN) controller has the capability of knowing the network topology and infrastructure. It also provides visibility into the traffic. As SDN logic and its architecture have evolved, controllers now offer integrated security functions as well. Among these functions are routing, firewall policies, and service chaining. These are implemented through the controller and controlled by software and applications.
According to the market database, this approach might utilize Network Functions Virtualization (NFV) concepts as a complementary approach. With the application of service chaining, the SDN controller may direct traffic flows dynamically to the appropriate network elements if and as needed. Security-Defined Software (SDS) is the overall model.
In the transition to SDN and NFV, networking practices and security architecture are evolving in profound ways. As implementation models, they realize the benefits of programmability, automation, and adopt the Software-Defined Security approach, to respond in a more dynamic, efficient, and intelligent way to the continuously rising threats they face today.
Secure Remote Access
When the COVID-19 pandemic hit the country, Connect Digital Security, a U.K.-based managed security services provider, had an advantage with secure remote access technology. As a result, the employees could pick up their machines, walk out the door, and work from home the next day. They could do anything remotely that they could do sitting at their desks in the office.
Secure remote access technology connects geographically dispersed enterprise users to the resources they need to perform their jobs without endangering network security. According to Gartner, organizations enabled remote access only to a handful of IT administrators and fewer business users before relatively recently. Almost every employee needs secure remote access since the global pandemic shook the enterprise.
According to the market database, to prepare for possible future crises and to support the post-pandemic hybrid workforce, addressing these demands will remain an enterprise priority in the future. According to the market database, by 2022, 67% of employees will have the capability of working remotely.
Enterprise Strategy Group (ESG), a division of TechTarget, explained how to secure remote access to support workers anywhere. As employee mobility and device hopping increase, security leaders must ensure sensitive data isn’t compromised. The Software Defined Security market and its 10-year business outlook can be understood using Global Market Database.
