Recently, and given everything that has happened this year, great importance is being placed on the development and improvement of cybersecurity. For this reason, we're going to write a post about the Cybersecurity in Software-Defined Networks (SDN).
SDN: What Is It, and What Are Its Benefits?
Se basa en la cloud computing and in virtualization technologies, using what are known as data planes and in-network programming. Numerous tests have been conducted, and so far, everything has been a success.
For this reason, we want to broaden our horizons and set our sights on much greater and more distant challenges: we want to plan a Large-scale network operation using SDN. We also intend to place a strong emphasis on internal cybersecurity.
Experts have conducted a study to analyze the Overflow Protocol y así describir el uso de la security at the Transport Layer Security (TLS) level. It does not have a default standard in place, and as a result, many providers do not use it. It runs the risk of being attacked and of fraudulent rules being created or modified that compromise the overall security of the system.
Ciberseguridad en SDN
La ciberseguridad en SDN It is based on five fundamental pillars: confidentiality, availability of information, authentication, non-repudiation, and integrity. Professionals who work with these systems must be able to protect data and devices and communicate over a secure network.
The first architecture that emerged as the basis for the SDN In 2006, it was based on a controller that was responsible for the autenticación, both at the host level and at the policy level. In that case, the proposal was rejected because it required a major change in the estructura de red y en los host which the company was required to install at the communication's end point. This could have caused a major problem for companies, as it would have required them to make significant changes to their structure.
Next, a new approach emerged, based on the previous one but using a centralized controller to enforce a global security policy and use switches that redistribute packets based on flow tables. This allows the company to manage fewer endpoints and thus better segregate data. The problem with this architecture is that if the main host is compromised, it can cause problems for the other endpoints.
En la actualidad, la arquitectura SDN allows the use of applications that, for example, help with Virtualization of Network Functions. The challenges facing developers and analistas de red These primarily involve the management and implementation of data and the existing interfaces between the different layers.
Cybersecurity in Software-Defined Networks (SDN) has tremendous potential in terms of network usage. For this reason, intelligent intrusion detection processes are beginning to be developed (IDS), intrusion prevention systems (IPS) and a scheduled analysis of the network itself. The systems will achieve a very high level of resilience against attacks by cybercriminals in a very short time, and we'll be there nosotros to provide the best service.
