Description: Virtual network security involves implementing security measures to protect virtual networks from unauthorized access and attacks. This is achieved through various techniques and tools that ensure the integrity, confidentiality, and availability of the data circulating in these networks. Key features include the use of firewalls, which act as barriers of protection between internal and external networks, and network segmentation, which divides the network into smaller subnets to limit access and contain potential security breaches. Virtual network security is crucial in environments where virtualization technologies are used, as these allow the creation of multiple virtual networks over a shared physical infrastructure. This not only optimizes resource usage but also poses new security challenges, as each virtual network can be a potential target for attackers. Therefore, it is essential to implement robust and updated security policies that adapt to the specific needs of each organization, thus ensuring a secure and reliable environment for the operation of its services and applications.
