Network Security : A Huge Problem

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.

Hacking is among one of the many things that all users have to deal with in technology of the current times. It has been an issue for some time and is only getting worse there are ways to attempt to fight off the attempts that will eventually happen. Some of these methods involve software that is able to be purchased online or in a physical store. Other methods involve software that is able to be downloaded via the internet and installed on a computer. The question is which ones are the best to use and offer the best defense against the possible cyber-attacks from potential hackers? This and more will be explained over the course of this paper in the next few paragraphs. The take away from this should be more methods that can be used to fight against the hackers that will target many end users in the world. The defense of the end users are one of the only things that can protect these end users from harm to the computers that are owned.

This rise in connected devices creates a greater need for cyber security in order to defend these devices and the personal data they contain. Mobile phones are now common place at most households in the United States with as many as 68% of US adults owning one as of 2015, according to Pew Research (Anderson). These devices contain a plethora of personal information ranging from credit card numbers, pictures, bank account information, and much more. Mobile phones are connected through various forms of communication such as cell networks, Wi-Fi, Bluetooth, etcetera. Mobile phones have vast amount of data and many access routes for criminals to access this data. Cyber Security experts, now more than ever, need to work towards protecting these devices and stopping criminals from accessing them. Another form of technology that has been on the rise are so called IoT devices, or Internet of Things. These are everyday devices that in the past, would not have been connected to the internet such as fridges, coffee makers, and thermostats, that are now becoming connected devices. These devices often are not protected by strong forms of security or any security at all. These devices provide easy access into their users lives and can in some cases be very dangerous if not protected properly. According to an article written for Forbes magazine the number of interconnected IoT devices could reach upwards of 30 billion devices by the year 2030 (Press). If these devices are not brought up to the security standards of modern laptops and desktops, then home and office networks alike will be at risk of attacks from hackers and criminals. More devices are being connected to the internet every day and as this number grows cyber security will become ever more important to ensure that these devices stay secure and safe for their

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.

It’s no secret that IoT, BYOD and mobile access have made these endpoints one of the most concerning network security gaps. As these devices continue to saturate the market, organizations are struggling to balance the productivity gains these devices deliver, against the security risks. There is no place where this risk is more pronounced than in organizations that are part of a nation’s critical infrastructure.

Protecting information and critical infrastructure in a cohesive way that quantifies policies and procedures is imperative for implementing a proactive privacy risk management plan. In doing so, you gain the necessary framework and principals to share essential operational data for use in cybersecurity while focusing on policy cohesiveness between intra government agencies, the private sector, and securing critical infrastructures. (Claffy & Kenneally, 2010).

The overall security for the networked environment is weak, and the team was able to move quickly through the information system and gain system level access on most of the attached hosts, within the scope of the penetration test. Had the organization been equipped with a firewall, the ability to conduct the following test would have become a more difficult task. However, because packets can move freely, the systems provide more data than they should. Secondly the team identified the requirement to segment the network. In its current configuration, Appendix B, the organization is easily exploitable. Coupled with a firewall, a segmented Local Area Network, and firewall to filter the local area traffic, the organization becomes a more

Networking security the process of taking physical and software preemptive evaluations to protect the underlying network foundation from unauthorized admittance, misuse, glitch, modification, demolish, imprudent revelation, thereby creating a secure platform for computers, users and programs to implement their permitted critical functions within a secure environment. Network security has become significant due to the patent that can be obtained through the Internet. There are essentially two different networks, data networks and synchronous network composed of switches. The Internet is considered to be a data network. Since the prevailing data network resides in computer based routers, information can be accessed by special programs, such

With a multitude of changes occurring in the technology field, it is critical that hospitals maintain the highest levels of security for their internal network as well as their public access network. Hospitals contain vital information about patients, treatment styles, employees and staff, as well as pharmaceuticals that are kept on the premises. The importance of protecting this information cannot be understated and a breach in security could cause a breakdown in all areas of the network, having a catastrophic effect on the entire hospital.

Technology is constantly advancing, which causes a need for mobile and wireless networks. However, the creation of mobile and wireless networks causes a need to increase security protocols and measures. Cell phones are now being used for sensitive work information, as well as laptops. Many people have the capability of working from home by using laptops issued by their employers. Using a home or public network is not always safe, it does not have the security and systems to monitor the network and access. Before any work is done on these devices the proper security needs to be in place such as firewalls, pop-up blockers, and private network connections. However, there are both advantages and disadvantages to the use of wireless networking and what is will be like in the future.

It is important for ABC Corporation to bring the network up to current security standards. Attempts to breach networks are becoming more sophisticated and difficult to defend against, as more powerful hardware is introduced and new security defenses become available leaving older measures unreliable. Aging networks that are improperly secured are more at risk than ever. It is not only important to ensure you have the proper defense at the perimeter but also internally on wired and wireless infrastructure. When considering network security controls, acceptable risk is often considered but needs to be minimized to provide the smallest attack surface for an attacker to exploit.

Securing Bring Your Own Device (BYOD) & Internet of Things (IoT) devices are currently two of the most challenging areas of network security. BYOD has been a trend for a number years now, yet many companies are still struggling to successfully secure these endpoint devices. Organizations are grappling with different security approaches. While some organization have not taken steps to secure these endpoints yet, other organizations have added Enterprise Mobility Management (EMM) technologies such as Mobile Application Management (MAM), Mobile Device Management (MDM), Mobile Content Management (MCM) and Mobile Information Management (MIM), or a

System security comprises of the procurements and approaches received by a system executive to avoid and screen unapproved access, abuse, change, or dissent of a workstation system and system available assets. System security includes the approval of access to information in a system, which is controlled by the system head. Clients pick or are appointed an ID and secret word or other verifying data that permits them get to data and projects inside their power. System security blankets a mixture of machine systems, both open and private, that are utilized as a part of ordinary employments directing transactions and interchanges among organizations, government orgs and people. Systems could be private, for example, inside an organization, and others which may be interested in community. System security is included in associations, endeavors, and different sorts of organizations. It does as its title clarifies: It secures the system, and additionally ensuring and managing operations being carried out. The most well-known and straightforward method for securing a system asset is by relegating it a special name and a comparing watchword.

Challenges using personal devices arise as the popularity of these devices increase by time. A recent survey claim that 69% of employees use their personal mobile/tablet devices to access company networks. The same survey says that even though 86% of employees make efforts to erase all contents from their devices prior to selling them, over 50% still contains big amounts of personal data. Some of the main challenges in BYODs are summarized in the following sub-sections [1].

In today’s world Network Security plays a vital role to protect the underlying network infrastructure from unauthorized access, malfunction, modification and improper disclosure. Network security helps to create a security platform for users, programs, and computers. Security became a major concern with the explosion of the public internet and e-commerce, private computers and computer networks. This white paper outlines the overview of network security threats and its solution which protects you and your organization from threats and malware and confirms that data travelling across your network is safe.
