Operating System Security Flaws Essay Example for Free

Operating System Security Flaws Essay 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. We will first look at some known flaws in Windows 7 and Windows 8. An Information Security Engineer at Google had decided to reveal a flaw that affected two of Microsoft’s newest operating systems that allowed attackers to obtain higher privileges on an unpatched computer. The vulnerability was caused due to an error within the ‘win32k.sys’ when it processes certain objects and it can be exploited to cause a crash or perform arbitrary code with kernel privilege. A more recent flaw in Windows has been identified as the Zero-Day Vulnerability; the Microsoft Windows Object Linking and Embedding (OLE) package manager remote code execution vulnerability (CVE-2014-4114) permits attackers to embed OLE files from external locations. CVE-2014-4114 flaw can be exploited to download and install malware on to the target’s computer. This vulnerability affects all versions of Windows to include; Windows Vista Service Pack 2, Windows 8.1 and Windows Server versions 2008 and 2012. The Microsoft technology allows rich data from one document to be embedded in another document or link to a document. The OLE is usually used for embedding locally stored content but this flaw allows the unprompted download and execution of external files. The attackers send the targeted individuals or corporations a spear-phishing email that contains a malicious PowerPoint (PPT) file attachment; this email is detected by Symantec as Trojan.Mdropper. The sent file contains two embedded OLE documents containing URLs. If the targeted individual opens the PPT file, the URLs are contacted and two files are downloaded which in turn will install the malware on the computer. When the malware is installed on the victim’s  computer, this creates a back door that allows the attackers to download and install other malware; the malware can a lso download updates for itself to include an information stealing component. Microsoft is advising customers that there is no patch currently available for this vulnerability; they have supplied a fixit tool that decreases the attacks. While the present exploits are using PowerPoint files to deliver the malware, given the type of flaw, they may start using different office files such as word documents or excel spreadsheets. The second zero-day vulnerability is CVE-2014-4113, which is a local elevation of privilege vulnerability; this flaw has been seen in attacks against Windows Server 2003/R2, 2008/R2, Windows 2000, Windows Vista and Windows XP SP3. This flaw cannot be used on its own to compromise a victim’s security. The attacker would need to gain access to a remote system running any of the above lists operating systems before they could execute code within the context of the Windows Kernel. (Sandworm Windows Zero-Day Vulnerability Being Actively Exploited In Targeted Attacks, 2014). Microsoft’s security advisory states the company is vigorously working to provide broader protections to their customers; the company states that the resolution of the issue may include providing a security update through a monthly patch update or providing an unscheduled security update. As stated above Microsoft issued a temporary fixit tool that can be applied to 32-64 bit versions of PowerPoint 2007, 2010 and 2013. This can be used until an official patch is released. Also another countermeasure to avoid downloading malware on to your operating system is not open any PowerPoint Presentations or documents from unknown parties, even mail from known addresses should be avoided unless you can confirm with the sender that the email was intentionally sent. Many emails are compromised because some individuals make their passwords to easy or they have downloaded spyware and the attacker gets that information and uses their email to send out their virus to other users. I have received emails from my mother when I didn’t expect them and I would inform her that her email had been hacked. Many are not aware that this has happened unless they are told, References: Google Engineer Finds Critical Windows 7 / 8 Security Flaw. (2001-2014).

Extended Breastfeeding: Is It Healthy? :: Breastfeeding vs. Formula

Is it unusual when the cover of TIME magazine depicts a young child being fed by the breast of his mother? Believe it or not, there are mothers who breastfeed their children up to the age of six. This trend can be classified as attachment parenting. Attachment parenting, as explored by TIME’s Kate Pickert, is a controversial issue that has been the topic of discussion for decades. Thus, whether attachment parenting is acceptable or not has been long debated, and its controversy can lead to some oppositions. Firstly, the cover’s title, â€Å"Are you mom enough?,† which advertises this parenting style, is questionable to working mothers. For instance, what does it even mean to be mom enough? Secondly, a major criticism of this parenting style is that it could lead to dependent and spoiled children. Then, Dr. Bill Sears, an advocate for this style of parenting, suggests to mothers that attachment parenting prevents bullying. Based on these objections, it appears to some people that there are more positive benefits associated with weaning a child off of breastfeeding before they reach a certain age. The cover of TIME magazine uses pathos to invoke acceptance as a child stands clinging on to his mother’s breast, along with the words, â€Å"Are you mom enough?† This assertion can empower some women to do the accepted thing; yet, offend other women, who don’t agree, at the same time. A mother’s primary role is to nurture and guide the growth of her family. The woman, in particular, displays this role in which, â€Å"her charge [is] to oversee her child’s physical, intellectual, and spiritual development† (Plant 2010). However, there are many ways to manage a child’s well-being, aside from breastfeeding up to the age of six. Therefore, the cover can imply that mothers. who don’t practice attachment parenting, are not woman enough. Moreover, it doesn’t necessarily make a mother a bad parent if she doesn’t attend to her child’s every cry, sleep beside him at night, or breastfeed him throughout his entire adol escence. The World Health Organization (WHO) recommends that infants should be exclusively breastfed for the first six months of life. Afterwards, their studies suggest that the child â€Å"should receive complementary foods that are nutritionally adequate (providing sufficient calories, protein as well as micronutrients needed for proper growth) and safe while continuing to breastfeed for up to 2 years or more† (Children’s Health). Based on their study, there is a positive correlation between weaning a child completely off of his mom by two and his level of independence into toddlerhood.

The Little Rock Nine

The movie â€Å"The Little Rock Nine† is based on an event that happened in the 1950’s. The movie is based on the first time that a school allowed black students into an all white school. This event happened in Little Rock, Arkansas when a school allowed nine black teenagers into their school. In this essay you will read about the respect that the black students got at the beginning of the movie and the respect they got at the end, how society has changed today, how this relates to the Hebrews experience, how this relates to moral values, and my personal experience on this theme. In the movie the nine black students got no respected at all. The students were treated the same as every other black person at this point in time. The black students took abuse and bullying that no other person would be able to take. They got pushed, threatened, excluded from events and even spit on. This was the respect they got when they first came to the school. The guards stationed around the school didn't even do much at times. They were afraid at times, because if they tried to retaliate they knew things would only get worse. Even people outside the school tried to get the students out of the school. There were rallies and marches, mostly led by parents, to get rid of the nine black students. Then things got even worse when bomb threats started coming in. Finally on of the students named Minnijean Brown started to fight back. Minnijean Brown was the first of the students to be targeted to recieve the most abuse. It started one day when she was just heading to class and a group of girls blocked the door to her next class. She asked them politly to move and when they didn't she tried to move in between them, but she got pushed out of the way. That was the start of the incidents. Eventually Minnijean was expelled for dumping a bowl of chili on students head that was blocking her way and refused to move. Minnijean was upset by this because the white people of the community got exactly what they wanted. The next target was Ernest Green. Ernest was targeted next because he was a senior and, if he made it, would be the first black student to graduate from Central High School. The white students and parents did everything they could to prevent him from graduating. One female student even tried to get him to like her so she could say he â€Å"harassed† her,but Ernest graduated 1958. These two students are probably the most recognized two of the Little Rock Nine becausse of what happened to them. Society has changed alot since 1958 in many ways. The Central High School in Little Rock is now 50% black students. The story of the Little Rock Nine relates to the Hebrews when they are in Egypt because they are being treated just like the nine black students. They were forced into labor every day and were beaten and spat on as well. This relates to moral values because everybody should be treated equal. Alot of people back then were Catholic, but they treated people diffrently, when everyone was actually the same. This relates to my personal experience because me and a friend of mine went through a little bit of this last year. It wasn't as bad as the Little Rock Nine, but it hurt. My friend and I were excluded from games some games in P. E. , we took alot of hateful phrases, and other things. Then around graduation they stopped and things went back to normal. The Little Rock Nine is a good example of what black peolpe had to go through in that point in time. I think the Little Rock Nine was and still is a great example of how racism can destroys people and their self esteem. And It also shows how brave some people were during the Civil Rights Movement. I also think it is very important that three of the Little Rock Nine graduated from Central High School which I think this is a great accomplishment. It also proves that blacks were able to do the same school work as whites.

Women and their Involvement in World War II Essay - 787 Words

Women and their Involvement in World War II Women had a huge role in the World War II that so many do not recognize. Women were involved in many different jobs that allowed them to step out of the ordinary norm as the â€Å"typical housewife†, and dive into fierce hardworking jobs that until then only a man could do. Women jumped into the factories and many different roles that contributed to World War II, because the need for more American workers was crucial. A few roles of women prior to the World War I consisted of cooking, cleaning, and caring for the children.

The number of working women rose from fourteen point six million in nineteen forty one to nineteen point fo ur million in nineteen forty four. â€Å"Women were not just motivated by wages or patriotism; but buy the feeling of independence that they gained from the work,† (Hughes 2). Without women laborers the US economy would have never been able to produce military hardware to be successful in the war. Even though women played a huge role in the work force during the World War II, they also played an even bigger role in the war itself. Women played several different roles in the actual war. â€Å"A few of women’s roles in the actual war of World War II would be army nurses, spies, pilots and entertainers,† (Scott3). Women served as army nurses during World War 11, there were than seven thousand active nurses on duty when the United States entered the war. â€Å"Women also served as pilots, on September tenth nineteen forty two, Nancy Harkness Love, with the support of th U.S. Air Transport Command, organized twenty five women pilots into the Women’s Auxili ary Ferrying Squadron (W.A.F.S),† (Scott3). Women pilots were used to serve non- combat flights, to free the men for combat flights. â€Å"Women spies of the World WarII , they were often successful and unsuspected since people suspected women that women’s properly roles were solely domestic,† (Scott3).
