In recent years, IoT has been on the rise, with billions of new devices getting connected each year. The increase in connectivity is happening throughout markets and business sectors, providing new functionalities and opportunities. As devices get connected, they also become unprecedently exposed to the threat of cyberattacks. While the IoT security industry is still shaping, the solution is not yet clear. In this article, we will review the latest must-know about IoT visibility & security and we will dive into new approaches to secure the IoT revolution.
IoT visibility & security in 2019:
1. IoT endpoint security vs network security
Securing IoT devices is a real challenge. IoT devices are highly diversified, with a wide variety of operating systems (real-time operating systems, Linux-based or bare-metal), communication protocols and architectures. On top of the high diversity, comes the issues of low resources and lack of industry standards and regulations. Most security solutions today focus on securing the network (discover network anomalies and achieve visibility into IoT devices that are active in the network), while the understanding that the devices themselves must be protected is now establishing. The fact that IoT devices can be easily exploited makes them a very good target for attackers, aiming to use the weak IoT device as an entry point to the entire enterprise network, without being caught. Besides that, it’s important to remember that network solutions are irrelevant for distributed IoT devices (i.e., home medical devices), that has no network to protect them.
Manufacturers of IoT devices are therefore key for a secure IoT environment and more and more organizations are willing to pay more for built-in security into their smart devices.
2. “Cryptography is typically bypassed, not penetrated” Shamir’s law
In recent years we see a lot of focus on IoT data integrity, which basically means encryption & authentication. Though very important by itself, it’s important to understand that encryption doesn’t mean full security. When focusing mainly on encryption & authentication, companies forget that the devices are still exposed to cybersecurity vulnerabilities that can be used to penetrate the device and receive access into the decrypted information, thus bypassing the authentication and encryption entirely. In other words, what’s known for years in the traditional cyber industry as Shamir’s law should now make its way to the IoT security industry: “Cryptography is typically bypassed, not penetrated” and therefore companies must invest in securing their devices from cyber attacks and not just handle data integrity.

According to a study by LogicMonitor, the number of applications hosted on-premises will decrease by 10%, to 27%, by 2020. In comparison, the number of cloud-native, more specifically serverless hosted applications, like AWS Lambda, Google Cloud and Microsoft Azure, will increase to 41%.
The trend to cloud, specifically serverless, and away from on-prem, is not new and of no surprise, as serverless hosted applications provide developers with a faster speed to market and allows for them to release new functionality on a more frequent basis. In addition, it can save organizations bundles in infrastructure costs. It has however left DevSecOps and security teams in a quandary. While they don’t want to impede development efforts, they are left with no choice but to place the security of serverless applications in someone else’s hands.
To alleviate this issue, there are several serverless security best practices that must be put in place in order to properly secure serverless apps launched by the developer.
Amazon Web Services (AWS) offers a huge variety of benefits for businesses, and organisations are increasingly opting for cloud solutions for their data, website, and applications. However, there are still some businesses using AWS that have not put the proper cyber security controls in place. Here we take a look at ten great tips to improve your AWS cyber security.
- Understand your responsibilities
When you work with any kind of web services provider you need to understand what you are responsible for and what will be managed by the provider. This is absolutely true in terms of AWS – where Amazon runs its so-called ‘shared responsibility model’. In this model AWS is responsible for protecting the infrastructure of the AWS cloud system including hardware, software, and networking.
On the other hand, you as the customer is responsible for customer data, identity and access management, firewall and anti-virus configuration, and issues such as data encryption. It can sometimes be necessary to work with outside agencies to manage your own cyber security.
Cybercrime affecting businesses has become so widespread that IT and network security professionals are always thinking about that next breach and the costs of recovering from it. This increased risk has also raised the demand for better virtual defenses to prevent the loss of sensitive organizational data such as personal consumer details and internal communications.
There is a substantial need for cybersecurity training. It’s something that many businesses are interested in, but implementing the right system isn’t easy. Physical labs are expensive, require significant time and resources, and aligning everyone’s schedules is often impossible.
Virtual labs are a great way for you to provide your customers and partners with access to the latest cybersecurity product demos and training. These labs are accessible from anywhere, customers can engage with them on their terms, they cost less, and increase the overall quality of the training.
