In 2022, IoT security features

IoT security features

The IoT allows us to connect to what is important to us personally or professionally. Regardless of where we are or what we are doing.

  • For example, one can remotely unlock their home to let in a neighbour while on vacation, or track pets or loved ones.
  • From a business perspective, IoT connectivity allows you to track global asset usage, cost, and performance, lowering costs and improving customer satisfaction.

Aside from the various advantages of such a huge connection, one major concern is security.

Until recently, online security was a hot topic, and as we learn more about connectivity, it is becoming more of a problem.

This blog will examine some of the risks associated with M2M projects.

The IoT security market.

It’s vital. New devices and technologies create new security problems for enterprises and hardware vendors when deploying M2M devices globally.

LoT security features

First, consider a physical security scheme that precludes illegal remote device access. A remote access security protocol that allows

  • Use specific SIM cards.
  • Disable SIM cards remotely in the event of a security compromise.

Using remote devices to send and receive messages is risky. They could be intercepted because they use public networks.

However, using public networks to communicate sensitive data demands extra caution.

EMnify recommends constructing private networks and APNs on security procedures to protect sensitive data.

The complexity of maintaining these devices and the data they exchange can be overwhelming. A system like this requires multi-layered security and authentication.

A management system hack might compromise the entire deployment of devices and their sensitive data.

We advocate a set of firewall settings and protocols that can automatically detect breaches or hacking attempts because having many devices makes security monitoring tough.

The following is a list of security features that we recommend using before any deployment:

IMEI security.

Most mobile devices have an IMEI number.

An IMEI lock protocol prevents a SIM card from being removed and used in another device.

Secure data transfer.

Use a private APN accessed over a VPN to ensure optimum data protection across devices.

An access point connects a device to a mobile network (3G, 4G, etc.) and the Internet. To be a private gateway, each device must be segregated from other mobile users.

A VPN is a private network that uses the Internet. Using this to access a private APN keeps all data off the public network.

Firewall on the web.

A firewall protects data sent from a point to the network.

Because M2M devices have limited computing power, they can not operate firewalls.

A network-based firewall removes the burden of packet filtering from the device, guaranteeing that harmful data never reaches the device or enters the network.

A firewall can be configured to monitor and prevent specific items or functionality. It can also detect intrusions or hacking attempts that defy pre-set rules.


Even though businesses are responsible for using secure systems to transmit customer and company data, manufacturers of connected products are also obligated to do so.

Using an embedded SIM card for GSM IoT connectivity, for example, helps secure a device’s data.

It’s also critical to keep your device’s security and connectivity systems updated, preferably automatically. Using a SaaS platform ensures automatic adoption of new management and security features.
