Cyber Security Vulnerabilities : Information Systems And Network

As basic users, security is one feature that most of us overlook when it comes to operating systems until it is too late. In this paper we will discuss the security flaws within the Windows Operating system, and then discuss countermeasures to fix the system flaw.

The world of cyber security continues to introduce new threats each year against network infrastructures and computer devices. In the recent years, the impact from cyber-attacks has wreaked havoc on many company brands and organizational reputations. As this issue grows so does the technology to prevent and protect against these malicious attacks. It is absolutely crucial for organizations and businesses to shift focus from defense for different types of attacks to improving safeguards to mitigate the loss of sensitive data when an attack occurs. In addition to the traditional security technology used to detect an attack, companies will have to include

As I stated before there are many different types of security vulnerabilities out there which can affect the integrity, availability and confidentiality of a resource. So the question still remains what exactly are these types of vulnerabilities? Especially since they range from software, hardware, networks and the people that use them. Firstly I will discuss the software vulnerabilities, more specifically in terms of web applications. This is because more than half of the current computer security threats and vulnerabilities today affect web applications and that number is ever increasing. (Fonseca, Seixas, Vieira, Madeira, 2014). When considering the programming language used to develop web applications you have PHP which is considered a weak language, on the other hand you have Java, C# and Visual Basic which are considered strong languages. It is important to note that the language used to develop the web applications is very important because although the different programming languages are similar overall, each one has different rules of how data is stored, retrieved, the execution methods, tables and so on. For example when I say how data is stored and retrieve, I am basically regarding to data types and data structures and how the programming language that is being used maps their values into type fields like strings for names, Int for numbers, or even Boolean for true and false statements.

When a computer connects to a network and engages in communication with other computers, it is essentially taking a risk. Internet security involves the protection of a computer's Internet account and files from intrusion of an unknown user. Internet security has become an alarming issue for anyone connected to the net. This research paper argues the need for security over corporate intranets that have been dealing with the lack of security within the internet and the numerous attacks and malware threats that hackers use to breach security measures. A corporation uses a private computer network that uses Internet Protocol technologies to securely share any part of an organization's

DTL Power Corporation is an electricity generating and distributing company headquartered in Santa Fe, New Mexico. Currently, they have 5.4 million electricity customers and 485,000 natural gas customers. Also, DTL Power has full or majority ownership of 14 nuclear reactors in 12 nuclear power plants. Additionally, it has 2 hydropower plants in the Midwest and 5 wind energy centers along the East Coast. Last year, incidents around the world involving nuclear reactors have led the company to increase security and safety regulations at its nuclear plants. Furthermore, the company is also researching additional environmentally friendly opportunities such as geothermal energy.

As such, he introduces a technique of identifying a spectrum of potential vulnerabilities and suggests procedures to deal with them. Systems Specification and High Order Language Implementation are categorized as items of high risk to attacks. Security Policy and Machine Language Implementation are classified as items of moderate risk of being vulnerable to attacks. Circuits Electronics and Device Physics are of low and very low risks respectively. He also discusses potential threats such as deceiving operating systems to grant access to file or data to unauthorized users through direct (overt) and indirect (convert) channels. Walker also says that lack of precise definition of trusted operating systems and the higher cost of building them are the significant drawbacks faced by the vendors. Vendors are concerned that if they build trusted operating systems, they might not be accepted by their customers. The only solution suggested by the author was to have someone or a company builds it, shares the technology used, and convinces the general public on the significance of it. Once it becomes accepted, then there will be a widespread use of trusted computer operating systems.

The common vulnerabilities in a CMS are unpatched or poorly patched plug-ins rather than the core system. Poor patch management represents a large

The purpose of the report is to explore the current vulnerabilities in the information system network and outline potential

Attacks on physical systems: In current days, only organizations are facing the security threat is not the case, even laptops and mobiles are entrusted with the most sensitive of information about the organization. These devices, whether they are company property or personally owned, often contain company documents and are used to log on to the company network. More often than not, these mobile devices are also used during conferences and travel, thus running the risk of physical theft. The number of laptops and mobile devices stolen per year is ever on the increase. Another threat affecting physical security is that of unprotected endpoints. USB ports and DVD drives can both be used to leak data and introduce malware on the network. A USB stick that is mainly used for work and may contain sensitive documents, becomes a security risk if it is taken home and left lying around and other members of the family use it on their home

Software vulnerabilities are the security faults, or shortcoming found in programming or in a working framework (OS) that can prompt security concerns. An illustration of a product blemish is a cradle flood. This is when programming gets to be slow down or crashes when clients open a document that may be "too heavy" for the system to peruse.

The greatest area of vulnerability and potential for damage or data loss of web applications and

There are many risks, some more serious than others. Some examples of how our computer and systems could be affected by a cyber security incident include manmade or natural disasters, improper cyber security controls, or malicious users wreaking havoc.

The software security is very important issue among all the software. All the software’s must have the good security in order to prevent it from the different attacks from the internet like the viruses and many other attacks online which can harm the computer sufficiently. The main purpose of the security of all the software’s is to avoid the malicious attack of the other things. The main thing is the function of the software for which it can be made. All the software’s are made up for the special purposes and they must be used for that purpose only in order to get the best results from them. but if you want to get a task done by a software which is not made for that particular task and that the does not allows you do that particular task, then you have change its code from the software is being made. This is where the software security comes into the consideration that whether the software is secured enough and does not allow the user to do that or it is east for the user to do that task and change the code. If the software security is not good, it means that anyone can change the main purpose of the software task and use it for the illegal tasks. In this way, it will because the problems for the owner of the software as software introduced by the producer must be secured. But if the software is well secured then, the no one will be able to change its main file and the software can only

If attacker have physical access to victim computer could easily copy information from it. An unauthorized user can change coding of operating system to bypass the security check, they could install malware, worms, or harmful viruses. Though system is secured by standard security, they could be able to boot computer using another working programs for boot the system using bootable USB drive or

There are a great number of security risks that could threaten the computer infrastructure. Below are the top 5:
