Building A More Secure System

Although the local authority takes the lead on safeguarding children and young people, and have an all-encompassing responsibility for safeguarding and promoting the welfare of all children and young people in their local area, safeguarding is everyone's responsibility when coming into contact with children and young people. All local agencies, including the police, health service and schools, have clearly defined roles and responsibilities under the Children Act 2004. They must not only promote the well-being of children but ensure that they safeguard children whilst carrying out their day-to-day functions. They must cooperate with local authorities in doing this

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.

Papa (2011), indicated to combat these issues administrators must consider protective measures for both internet and technology use (p.198). Protocols for teaching students how to use the internet appropriately must be put in place (Papa, 2011, p. 198). Antivirus and protection software must also purchased to “prevent extensive damage to existing computer systems” (Papa, 2011, p.198). Regrettably, despite our best efforts to maintain network security we must still face the possibility of people or physical threats such as:

Reasonable precautions should be taken in order to ensure the safety of personal files that may be on the user’s computer as they navigate through the Internet. Each situation is different.

When installing any operating system regardless of whether it is a Linux or windows based operating system it is essential that steps are taken to ensure the security of the operating systems. Ensuring the security of an installed operating system before for it is put into use is known as system hardening. System hardening is done by taking known vulnerabilities in an operating system and making security enhancement to mitigate these vulnerabilities. Thus, it is important to know the vulnerabilities which are posed by each operating system and the ways in which they can be mitigate. Below are three common vulnerabilities in windows operating system and recommendations on how to mitigate them.

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 article, which addresses security loopholes in modern computing environments, by Loscocco et al highlights what is and has been being done security wise in the past and how secure these implementations were and going forward what should be done to ensure in depth security which guarantees system wide security (1998). The article first explains features of secure operating system and why current systems implemented under the notion of application space security ultimately failed to safe guard the integrity and confidentiality of our assets. The article then continued with general examples of access control and cryptography implemented in the application space with no or little support from operating system and showed their vulnerabilities to attacks such as tampering, bypassing and spoofing. The article supplied real-life examples to support the evidence that building security in the application space without secure operating system is meaningless. The article raised concrete examples on mobile code security, Kerberos network authentication service, IPSEC and SSL network security protocols and firewall. The paper finally put an interesting remark that security implemented in application space without secure operating system is like “building a house in a pile of sand” and it also emphasized that secure operating system without better security on the

As soon as you buy a computer, Tablet or Cell Phone, The IT industry acts as if it is so proficient in instructing the buyer on how to stay safe on the internet. They recommend, certain software; that you can download, and then purchase, to maintain the security of your personal computer.

Computer viruses are minute program which is “embedded inside an application or within a data file which can copy itself into another program“(Adams et al, 2008 ) for the sole determination of meddling with normal computer operations. The consequences may range from corruption and deletion of data; propagation of virus on to network and deployment through attachments through emails in order to further creating havoc to all associated computing devices.

Lawton, G. (2008). Is it finally time to worry about mobile malware? Computer, 41(5), 12-14.

To understand the business of malware, one must understand how malware has evolved in the past twenty-five years. Malware, which includes all kinds of malicious software, was originally created to show the weaknesses of computers. The first type of malware, created in 1986, was a virus called “Brain.A. Brain.A was developed in Pakistan, by two brothers - Basit and Amjad. They wanted to prove that PC is not secure platform, so they created virus that was replicating using floppy disks” (Milošević). Even today malware is still used to check the security of machines.

This paper will discuss three main operating systems, Windows, Linux, and OS X. All three of these operating systems have features which are unique unto themselves. Although there may be arguments as to which one of these three operating systems is better it really all comes down to what features are needed for each user. This paper will describe the features that each of these operating systems has to offer.

This report will outline that it would be useful for our company to subsidize free distribution of anti-virus software to our home users. There will be analysis of the connection between the company 's network and home users and how this will help our company 's problems with viruses. I will discuss the other issues besides providing free software to home users that affect the network security of our firm. Additionally, I will describe the roles of top management/non-IT management, IT professionals, and end-users in maintaining network security. Finally, I will bring out the role that Robert Vamosi envisions for corporate customers relative to free antivirus software based on his article, “Antivirus software must be free,

Answer: Information Security is the practice of defending (guiding) information by considering the CIA Triad Principles which are Confidentiality (Authorize access), Integrity (Accuracy and Completeness) and Availability.

Many types of computer virus has been spreading in computers since 1960. The first a computer virus discovered in 1970 and called The Creeper virus on Arpanet browser (anon, 2013)
