Deploying IPSec for enhanced security in IoT connectivity

Internet of Things (IoT) devices have become increasingly prevalent in domestic environments as well as in different industries around the world. The current trend strongly indicates that it won’t be long before IoT devices outnumber end-user ones by four to one.

IoT technology has already been applied to facilitate and enable many industry processes and IoT devices can now also be found in smart homes, smart cities, agricultural applications, healthcare scenarios and a host of industrial settings. Their popularity also means, however, that ensuring their security is of utmost importance.  

Changing passwords, using strong encryption, disabling unnecessary features, and constantly monitoring your network do not cut it anymore. As a pioneer in the IoT industry, melita.io offers IPsec as the best & widely deployed protocol to facilitate IoT device protection and network communication security.

IPsec or Internet Protocol Security is a sophisticated protocol suite used to secure communications over IP networks. It provides authentication, integrity, and confidentiality for IP packets by encrypting and decrypting them. IPsec can be used in a variety of scenarios, including site-to-site VPNs (Virtual Private Networks) and to secure communications between IoT devices and their respective server networks.  

As with any device that is connected to the internet, IoT devices are vulnerable to various types of security threats such as tampering and denial of service attacks, but by using IPsec from melita.io to encrypt and authenticate their communications, the connectivity between IoT devices and the respective cloud-based servers can be protected.

IPsec incorporates several technologies and methods to encrypt data. In truth, it is a complex web of routes and processes but to put it simply it involves the following five steps:

1. Identifying interesting traffic
2. Establishing a secure connection
3. Building an IPsec tunnel
4. Funnelling data through the encrypted tunnel
5. Deleting or timing out the tunnel

In addition to all this, several protocols such as Authentication Headers (AH), Encapsulating Security Payloads (ESP) and Internet Security Association and Key Management Protocol (ISAKMP) play vital roles in establishing the desired security levels.

With strong encryption, authentication, and integrity, as well as wide availability, compatibility and cost-effectiveness, IPsec from melita.io provides the most effective solution for secure connectivity with IoT devices.
