The Core Layers Of Defense

Defense in depth identifies the need for many security layers to be utilised in defense of the system from the bottom as physical security to the top as Data security.

While IoT devices holds much promise, there are still many security issues that need to be addressed. These security issues can have a significant impact on everyday life, such as causing damage, disruption to business operations, and in some cases even loss of life. Having all your devices interconnected using IoT such as lighting, thermostats, doors, and elevators, seems convenient but in fact this poses a great security risk. If these risks are exploited it could disrupt power or lighting which could lead to a loss of life if it were something like a hospital. Addressing these security risks will lead to more efficient and safer to use IoT devices but companies will have to identify them in their devices first (Tankard, 2015).

The idea behind defense in depth is to manage risk with diverse defensive strategies, so that if one layer of defense turns out to be inadequate, another layer of defense will hopefully prevent a full breach. This principle is well known, even beyond the security community; for example, it is a

"Something that has been mentioned indirectly a few times already is the concept of defense in depth. The concept of defense in depth originated from the military and was seen as a way to delay rather than prevent an attack. As an information security tactic, it is based on the concept of layering more than one control. These controls can be physical, administrative, or technical in design. We have looked at a variety of physical controls in this chapter such as locks, doors, fences, gates, and barriers. Administrative controls include policies

When computer security experts discuss their trade, the term “air-gapped computer” may crop up. To be “air-gapped” is to be not connected to any network in any way, thereby preventing remote access. With ordinary computing devices such as laptops and smartphones, this is a viable, easily usable, and powerful option. Conversely, and by design, Internet of Things devices operate only when communicating with the Internet, and, as such, this common dependence is their most critical weakness. Because constant connectivity has such severe consequences, especially when considering essential utilities, the U.S. Department of Homeland Security considers “IoT security … [to be] a matter of homeland security.” In the Department’s “Strategic Principles for Securing the Internet of Things (IoT),” six best practices are suggested for all producers: Incorporate Security at the Design Phase, Advance Security Updates and Vulnerability Management, Build on Proven Security Practices, Prioritize Security Measures According to Potential Impact, Promote Transparency across IoT, and Connect Carefully and Deliberately. While these procedures would certainly help alleviate the negative impact the IoT is likely to have, capitalism’s frantic speed makes it unlikely. Because of strict deadlines, many technology devices suffer from

Because IoT is creating its own ecosystem, the biggest challenge for the industry is how companies secure and manage the exponential growth of decentralized endpoint devices. Unfortunately, most security experts only know how to defend against attacks from a centralized perspective. Most Chief Information Security Officers (CISO) only understand centralized networks and depend on choke points or linear cyber kill chains that focus on traditional perimeter and inbound security protocols to defend against malware, viruses, and other attacks that inevitably overwhelm networks and damage servers, devices, and workstations. One of the potential

It has been demonstrated that a number of interoperable systems must be implemented to fully protect a network; a strategy known as Defense in Depth. Due to the multitude of security devices and device categories available, it can be very difficult to identify the correct tools for meeting security

The entire cyber security industry is in a period of growth. As both corporations and private consumers are becoming aware of vulnerabilities with their online presence cyber security firms, have learned how to offer in-demand solutions for a wide variety of customers. Within the field of cyber security, there are several different types. These different types of services range from protection on the Internet of Things to producing devices to protected connected cars or phones. Each of these areas are expected to grow by the year 2020 with some being more in demand than others. In the article, “Cybersecurity Market Reacher $75 Billion in 2015, Expected to Reach $170 Billion by 2020,” Steve Morgan notes that, “the hot areas for growth are security analytics / SIEM (10%); threat intelligence (10% +); mobile security (18%); and cloud security (50%)” (2015) . Additionally, the Internet of Things has seen new cybercrime which has driven spending up in this area. Morgan comments that the Internet of Things security market will expand to $29 billion by 2020 (2015). Firms that offer these demanded services are in the best possible position going forward. In addition to the existing services, firms must strategize around future security issues.

Internet of Things (IoT): With many more devices in use in the enterprise, many of which IT may not be aware of, there are many security vulnerabilities that are added to

This executive summary will focus on the “Defense in Depth” which is a comprehensive security strategy that helps prevent, respond and formulate processes to strengthen IT security.

In this paper, I discuss some of the security challenges that the IoT architecture has to address. I also compare the challenges that were inherited from the technologies related to the internet and those that appear in IoT from present networks.

The Internet of Things is a vision of a global network that connects various physical world objects to the IT infrastructure. This vision has been inspired by the success made in emerging technologies such as Radio-Frequency IDentification (RFID), wireless sensor networks, and mobile communication. The realisation of such a global object network will allow seamless interaction and cooperation between the real and logical world.

Abstract: The presence of smart things around us is growing rapidly. The world as we speak now is filled with crores of smart things, collecting rich amount of data. This paper is a general survey of all the security issues existing in the Internet of Things (IoT) along with an analysis of the privacy issues that an end-user may face as a consequence of the spread of IoT. The survey is mostly focused on the security loopholes arising out of the information exchange technologies used in Internet of Things. Countermeasures are discussed for only some of these security drawbacks in this paper.

The Internet of Things is a complex, innovative system rooted in the idea of connectivity. Individual artifacts that transmit data and information amongst each other ensure a smooth and coherent experience based off their ability to communicate through internet connection, sharing the same network to create incomparable efficiency and convenience. The Internet of Things is constantly developing to work in new areas and scenarios, further securing its essentiality in the domain of the technological future

The nature of security makes its implementation more difficult, since users are not security oriented by default, not deliberately but instinctively. Defense against attacks should be deployed on end-systems as well as LAN-wide boundary controllers. In addition, it better to specify a white-list of hosts that should never be blocked. The white-list is a simple means to prevent spoofing attacks from tricking the defense into blocking essential services (ÖNDER 2007).
