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.

The exponential increase use of the Internet to communicate, conduct business transactions, access personal banking, healthcare, education at confront of being anywhere has become an everyday lifestyle for many people around the globe. This reliance on computers, laptops, devices and other Internet of Things to access the Internet means, organizations, businesses and the government have also seen an increase occurrence of sophisticated attacks.

Several procedures can be included in this policy including the importance of responding immediately to any intrusions that are detected, utilizing secure encryption for any internal or external messages, instituting regular audits to make sure security precautions are followed, implementing all vendor supplied security update patches, logging activity to detect any unusual events, and following news and computer information reports about new threats being circulated (Haring,

Regardless of the organization’s size, there should be a comprehensive security plan in place. This ensure that personnel will understand regulations and follow protocols. Be sure to require that all employees successfully complete an annual security refresher course, such as through a webinars or online training module. It will also help management successfully respond to and resolve IT emergencies. Security plans should be customized to fit the needs of every organization. There are many security plan ideas and templates available online.

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

The senior management of the company is committed to achieving a superior security governance by treating INFOSEC as a crucial business component. The aim of the policy is to create a security conscious environment and to exhibit to all parties, internal and external, the application of fundamental security principles notably taking responsibility for information security, applying security controls in relation to the risks and individual accountability.

The Internet of Things offers many opportunities for businesses to enhance the efficiency of their services and products, find new streams of revenue, slash their operating costs and complete their digital transformation. However, as the number of connected devices increases, unprepared organizations may find themselves overwhelmed by the need to step up their cybersecurity game and become more proactive when it comes to protecting their data and systems. Companies manufacturing smart devices are blazing new trails in the technology world, and as is true for all innovative technology, there are still many things that have yet to be

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.

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.

Security policy: Firms need a formal security program which must be accompanied by formal executive support. This lays the groundwork for a successful information security program. Firms must also consider security policy as a living document that is subject to adjustments as the organization evolves.

Smart and IoT devices range from mobile phones, televisions, cars, heart monitors and refrigerators. Each of these devices empowers us to simplify and make our lives more convenient. These devices allow us easier access and share data but comes with a certain amount of risk. The increase of smart devices has also increased the number of cyber threats and attacks. The cyber threats that plague these devices are consistently getting more advanced and harder to detect but they consist of Trojans, viruses, botnets, and advanced manipulative devices. Cyber security is an emerging field of Information Technology (IT) that requires a lot of attention but with the growing threats IT professionals need to be well versed in the threats that could

Today we live in a world where new technology is no stranger to our everyday lives and as technology continues to grow, security needs to evolve with it. Security is one of the most important aspects of a company needed to succeed. The internet as we know can be the chance for opportunity for a business to constantly make money whether it’s the day or the night but the internet also holds the opportunity for an unwanted guest or an intruder to access the company networks. There is a need for a clear cut relationship between techniques and technologies that ensures protection to the company and allows the company to continue its daily services.

The forecasts point that then number of Internet of Things devices by 2020 will be around 25 billion, which is an exponential growth compared to 5 billion devices connected at this moment, while these systems are still considered weak on security measures. The reasons why security is not strong enough rely on their poor management design and services offered and other known security flaws.

The human and technological aspects of cyber threats changed dramatically in the past year. Witnessing innovative techniques blended with the outmoded, resulting in highly evasive attacks. Recently we have seen sizeable business, corporations, governmental agencies, and banking institutions, which we perceive as extremely secure, broken into. Vulnerabilities, uncovered by hackers who in turn exploit them in out-of-date infrastructure standards and developments such as the Internet of Things (IoT) have emerged to present an entirely new set of infrastructure challenges.

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.
