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.

An important part of this training will involve communicating key parts of the security policy so that employees will have an adequate understanding of potential threats and their remedy.

A security policy will be in affect starting today. As a set of new rules are to be abided by that will protect our organization from cyber theft and harm. We will cover an area that where are lacking in strength to protect our company from computer viruses. These areas will protect us from virus and spyware, firewall, and intrusion prevention.

Defense in depth is a practical strategy for achieving information assurance in today’s highly networked environments, as defined by the NSA, which first applied the long-standing military strategy to network security. The basic premise of defense in depth is that layering security controls within a computing environment helps slow down an attacker’s progress should she/he gain access (K. Teitler, 2016). The defense-in-depth strategy that was created by the NSA is very practical in finding information. The steps and processes that are taken into consideration are for each system to draw out any vulnerability that may be present. Each step has a different job that delivers different results than the rest. What the NSA Information Assurance based defense-in-depth strategy is they

Previous studies showed that the more an organizations’ top leadership engage in creating the information security environment, the more employees are willing to be compliant with the policies (Chen, Ramamurthy, Wen, 2012). This is because more commitment, monitoring and training are being in place with respect to information security policy and preparation. Therefore, in this study the three hypotheses will be a positive relationship between management engagement, regulation and training of information security and employees compliance with these policies.

Webster characterizes "policy" as a "high-level overall plan embracing the general goals and acceptable procedures". It is, by and large acknowledged that an organization's information security policies should be the premise of its information security program. Particularly in case of global organizations, the requirement for sensible policies and the issues intrinsic in creating them are exceptionally critical. This paper serves as a dialog of some of the most common data security strategy-related matters that are common to global organizations and offer some approaches to resolving them.

Defense-in-layers is an approach that advocates for applying security measures in overlapping layers to ensure that the whole security posture is covered. The security layers are to complement each other by ensuring that an unmitigated vulnerability at one layer is mitigated by another control available within another layer. Figure 1 illustrates how the defense-in-layers approach works.

Security policy must be created and train personnel against attack like not opening suspicious or unidentified emails, keep restriction on unsecured websites etc.

A current trend in cyber security, known as the internet of things (IoT), covers the boundaries of the net to include an extensive range of computing devices. Linking a wide array of IoT devices to the Internet presents many challenges. Due to the gathered data being exposed to a widespread amount of internet users, the main challenge is security. Most IoT devices on the market are low-tier and have limited functionality, because of this, many standard security strategies cannot be implemented to secure IoT systems. This leaves a door wide open for exploits and attacks both towards services of IoT and the whole internet itself. Most of these security issues can be resolved by following a unified IoT framework that runs on all IoT devices.

There is a revolution underway that has the potential to be staggeringly transformational and, at the same time, highly disruptive; it is currently called the Internet of Things (IoT) trend. IoT (also referred to as “Internet of Everything”) devices have embedded network, computing and other information processing capabilities, which allow these devices to be interconnected. The number and types of devices that are being manufactured with these built-in IoT features are increasing rapidly. It is imperative to take notice of the IoT trend because it has a strong potential to redefine the Security risk equation within many enterprises.

Internet of Things is a new technology that delivers communication among billions of smart devices via the Internet such as smart car, vending machine, smart house, health system and business system, etc. Nearly 50 billion devises and sensors will be connected to the Internet by 2020 and most of them will perform their duties without having security. In addition, the critical mission of a massive interconnected devices are security and interoperability. Hackers will use more complex tools and techniques to breach the network system. Hence, companies should establish strong security countermeasures and the best approach to provide superlative is security by deploying multilayer security method which is called defense in depth. Defense in depth is considered as a vital part for securing the Internet of Things because defense in depth eludes a system from facing single point of failure. This paper discusses the seven core layers of defense in depth approaches which are policy, procedures and awareness, application security, data security, physical security, host and server security, network and perimeter security, and wireless security.

As networks continue to increase with industry growth, information security demands more and more attention. Security breaches are triggering a lack of trust among patrons and loss of revenue to many businesses. Protecting an organization’s data is the responsibility of any user who accesses a network or maintains a network. Employees—usually those outside the IT team—require proper training and a sense of urgency to prevent attacks.

Fundamentally the security viewpoint characterize as security set of courses of action and its innovations that permit the holders of the assets in the framework to security dependably control who can get to which of these assets and The who alludes to the individuals and bits of programming thus on that type of the set of on-screen characters in the framework who can have a security character and security and experts regularly allude to such has the performing artists as the same principals. Its assets are the framework parts that are viewed as touchy and those to security viewpoints get to that ought to must be controlled, for example, the subsystems and information components and operations that are access to the assets are

Our goal is to analyze the network security problems of the Internet of Things and to find a possible solution for the problem.

Security is one of the major concerns of the internet of things. As billions of objects will be connected to it in the future. There has been an ever increasing need to address the security issues related to the IoT. The data transmission across the networks need to be monitored and protected from thefts and unauthorized malicious attacks. Different types of protocols and security measures are available in the existing internet scenario but most of them have limited applicability in the domain of IoT.
