The Embedded Linux Security Handbook

Welcome to the Cyber Security Landscape

Cue up the music. Welcome to the Jungle. The cyber security landscape is ever-changing and evolving. One could easily compare it to the mercurial New England weather patterns in the Northeast of the United States. Such weather can be dangerous for a hiker; similarly, such changes in cyber threats can be devastating for a technology solution.

In the coming chapters, we will dive deeper into the realm of Linux-embedded systems (or embedded Linux systems, also known as Linux appliances, or simply appliances) and exactly how you can apply this new knowledge to secure your solutions. We’ll make this journey together, and at the end of the tunnel, you will be best positioned to build a better appliance.

This chapter is here just to set the foundation of Linux-embedded systems before we dive deeper. In this chapter, we will cover the following topics:

  • What is a Linux-embedded system?
  • How are Linux-embedded systems used?
  • ...

What is a Linux-embedded system?

It’s probably safe to assume that if you’re reading this book, you may have some knowledge of what your company defines as a Linux-embedded system. To truly have a rich understanding of this subject, let’s review the appliance model for creating sellable solutions.

The appliance model provides solutions and services that an organization (or individual) cannot easily build for themselves. This also addresses another limitation; oftentimes, users of these appliances have little to no access to any technologists who would take on ownership of the care of said solution. The appliance model is most prevalent in home consumer electronics but touches every known vertical in the industry.

Most appliances leverage purpose-built hardware and have unique form factors that best enable their usage. These solutions are all around us every day. Some easily identifiable consumer appliance examples would be your home’s Wi-Fi router...

How are Linux-embedded systems used?

Linux-embedded systems are everywhere. Most people don’t give it a second thought. I venture the guess that you reach for one of these things when you first wake up in the morning and engage with it countless times every day. Your smartphone is a Linux-embedded system and, in my opinion, is an awesome example of one.

Embedded Linux systems surround us; some with stealth, others with pure elegance and entertainment, with all the beauty and grace their builders have instilled in their design. These appliance solutions run a massive range of use cases. Some are a complete solution and others are but a simple component to a greater ecosystem or solution.

Most, when successfully designed and implemented, provide services to their user community seamlessly without the user even having to think about what is happening under the covers. Much of this must be credited to how resilient, lightweight, and flexible Linux solutions can be. A Microsoft...

Why is securing Linux-embedded systems so important?

Why is securing Linux-embedded solutions systems (appliances) so important? Well, this answer truly has multiple aspects depending on who you ask.

The most obvious answer would simply be to prevent liability and loss of credibility in the marketplace. Lately, it seems that there’s an ever-growing list of companies whose offerings have become compromised and, as a result, their customers are grievously impacted.

The impact of such a breach can be the loss of personal information for the users (insert gasp here!) or even worse, unauthorized access to systems or data without the knowledge of those running the systems. Each year, these breaches result in billions of dollars in correlated losses and open these companies to legal action by their user base. The image impact on one’s brand can last far longer in people’s minds than you’d think.

It’s highly documented that data leaks, breaches,...

Summary

In this first chapter, you will have gained a solid understanding of how an embedded Linux system is defined. We’ve shown you some wide-ranging examples of where embedded Linux systems are leveraged today. Most importantly, we’ve reviewed some critical reasons why having these devices delivered to their customers as securely as possible is mandatory for those building such solutions. In the next chapter, we’ll dive deep into why security starts with a great design.

Can I download the code files for Early Access titles? Chevron down icon Chevron up icon

We try to ensure that all books in Early Access have code available to use, download, and fork on GitHub. This helps us be more agile in the development of the book, and helps keep the often changing code base of new versions and new technologies as up to date as possible. Unfortunately, however, there will be rare cases when it is not possible for us to have downloadable code samples available until publication.

When we publish the book, the code files will also be available to download from the Packt website.

How accurate is the publication date? Chevron down icon Chevron up icon

The publication date is as accurate as we can be at any point in the project. Unfortunately, delays can happen. Often those delays are out of our control, such as changes to the technology code base or delays in the tech release. We do our best to give you an accurate estimate of the publication date at any given time, and as more chapters are delivered, the more accurate the delivery date will become.

How will I know when new chapters are ready? Chevron down icon Chevron up icon

We'll let you know every time there has been an update to a course that you've bought in Early Access. You'll get an email to let you know there has been a new chapter, or a change to a previous chapter.
