Network Security And The Security

Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also

Provides multi layered security: Security starts from physical layer from protecting against ARP Cache, intruders, vandals and thieves. Physical security is provided based on the needs, maintenance

Attackers attack the network by identifying a weak point in the network and create a network threat. There are four primary classes of threat: Unstructured Threats, Structured Threats, External threats and internal

Patients come to the hospital expecting high-quality treatment and also that their privacy will be respected. Data infiltration costs hospitals over 6 million dollars a year (Fields 2010). Thus, encryption of all data pertaining to both patients and employees is vital: preferably encryption that cannot be turned off 'at will' by careless employees. All employees, regardless of their position in the organizational hierarchy should receive training in best practices about how to manage data, including not opening suspicious emails and not leaving computers on without logging off of their accounts first. IT personnel should monitor organization-wide suspicious activity, such as unusual log-in times or repeated attempts to log in with incorrect passwords. All staff members should be required to frequently change their passwords and use complex combinations of words and letters.

Hospitals are increasing the use of networking through computer systems and devices to easily access electronic health records, medical imaging, asset tracking, communications, vendor software-as-a- service solution, and patient monitoring. It has become an integral part to the lives of medical staff and patients everywhere. With the use of networking in the hospital, it’s becoming a challenge to protect the privacy of patients’ health records and securing electronic data since its vulnerability to a wide variety of security threats. According to a 2017 Cybersecurity news article, healthcare cybersecurity attacks rise 320% from 2015-2016, making the healthcare industry suffer the most cyberattacks that are happening. (1)

Security is a fundamental aspect of any network infrastructure. The goal is to always have the most up to date programs and protocols to ensure the protection of the network. No aspect is too small to over look. That could mean the difference between a secure network and a compromised network. The best way to achieve this is to break down every level and approach each one as a separate entity and secure it. Then you can modify it to suit the needs of your network.

With the increasing use of technology today with computers, there are better ways we can came up with to stop vulnerabilities in a network. As organizations increase their reliance on, possibly distributed, information systems for daily business, they become more vulnerable to security breaches even as they gain productivity and efficiency advantages. Network security is the becoming more important to a business because of the networks and applications. You never know when someone is coming for your business system. Looking at every strategy you have going on for your business. Need to have the set of tools for the security walls to be high. When dealing with hackers or competition all servers not to be access easily. There is a large amount

During this research I will discuss the challenges that the Healthcare Industry face and ways to mitigate these risks. It will also discuss security safeguards that will assist with preventing data breaches, from physical security up to network security. Protecting the organization data is the most important thing in a Healthcare facility. In the Healthcare industry, Health Insurance Portability and Accountability Act (HIPAA) has security rules that were established to protect individuals’ electronic personal health information (ePHI). There has been countless number of data breaches lately in healthcare facilities. They are at a much-much larger risk with the demand of healthcare facilities switching all of the data to an Electronic Health Records system. “Electronic Health Records is an electronic version of a patient’s medical history, that is maintained by the provider over time, and may include all of the key administrative clinical data relevant to that persons care under a particular provider, including demographics, progress notes, problems, medications, vital signs, past medical history, immunizations, laboratory data and radiology reports.” (Centers for Medicare & Medicaid Services, 2012) There has been a rule created called the “Breach Notification Rule” which I will explain in detail.

In the future organization need to take a proactive approach to the network 's security. This strategy of safeguarding the network as well as the patient data, such as scanning and social engineering should be mandatory as opposed to best practices. As the case study shows a major breach had a drastic impact on the healthcare organization and efforts should have been made ahead of time to prevent disaster. Organizations should understand security and risk budgeting and learn how to gain support from the board level for the investment needed to protect data. The industry should push the government to include required annual Health Information Trust Alliance (HITRUST) assessments compared to the current HIPAA [7]. HITRUST is an organization developed by healthcare and IT professionals to help healthcare organizations protect patient information better than HIPAA guidelines. If government mandates shifted towards HITRUST standards the healthcare industry as a whole could benefit across the boards and it can focus more on the patient care and less on the fear of an impending data breach. As mentioned in the previous sections these software and techniques won 't 100\% prevent attacks, but they will definitely help prevent and detect attacks beforehand.

The eighth layer is crucial whether designing an input scheme or troubleshooting network connectivity (Did the eighth layer plug-in and turn on the system?). Within the Open Systems Interconnect (OSI) model, the user is the only part that does not have universal standards, best practices, predictable competencies, and brings free will along with external influences. By abstraction, the user layer is the human element, which makes it responsible for building Cybersecurity systems, developing governance on use, and exercise safeguards to keep systems safe.

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.

Let's analyze the various attacks and threats to which our network can be a victim. For a better understanding I'll start from the most external layer of the network.

According to Kizza (2013), the rapid growth of networking has led to increased security risks. Many of these risks are as result of hacking, improper uses of network resources and network device vulnerabilities. Awareness of the various weaknesses and vulnerabilities is vital to the success of current networks (Kizza, 2013).

You can think of network security as an insurance policy in a dangerous new world. In the good old days of centralized processing, is all you had to do was simply lock the computer room door and restrict entrance access. Those days are long gone in light of decentralized processing, the internet and vast communi-cation networks. Personal data and transaction security through networks is of paramount concern when processing through the expanding networks held by government and private enterprises. Network security in itself refers to a collection of tasks or plans that are implemented to ensure data privacy. An overall plan is enacted with security profiles enacted on a multilevel structure allowing various
