Security Enhanced Linux (Selinux) Essay Security Enhanced Linux (Selinux), Chroot Jail, and Iptables Three of the most important types of Linux security technologies are Security Enhanced Linux (SELinux), chroot jail, and iptables. This security measures aide in the subversion of theft and malicious activity. We will discuss these items in depth to address who created them and for what reason. Along with how these technologies changed the operating system to enforce security, and the types of threats that these security systems are design to eliminate. Security Enhanced Linux was released in December of 2000 from the National Security Agency (NSA), under the GNU general public license. SELinux is not a Linux distribution; it is a set of kernel modifications and tools that can be added to a variety of Linux distributions. SELinux is currently a part of Fedora Core, and it is supported by Red Hat. Incarnations of SELinux packages are also available for Debian, SuSe, and Gentoo. Security-enhanced Linux is a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible Mandatory Access Control (MAC). The Chroot system call was introduced during the development of Version 7 Unix in 1979, and added by Bill Joy on 18 March 1982, a year and a half before 4.2BSD was released in order to test its installation and build system. A chroot on a UNIX based operating systems, like Linux, is an operation that changes the apparent root directory for the current running process and its children. A program that is run in such a modified environment cannot name or access files outside the designated directory tree. On a web server, it is very useful for the security of shared hosting accounts. Without a chroot jail a user with limited file permissions can navigate to the top level directories. Although that user does not have permission to make changes, they can invade the files and access information. An important use of chroot is it’s utilization within virtual environments. In a Virtual Private Server, the user has a complete operating system within a chroot directory. This user has root privileges for his or her own account, but can’t access higher directories or be aware of their existence. Virtualization is great for test environment that can be set up in the chroot for software that might be too risky to deploy on a production system. Virtual environments are often used for compatibility issues. Legacy software or software using a different interface must sometimes be run in a chroot because their supporting libraries or files may otherwise clash with those of the host system. Also chroot is often used for recovery purposes. A chroot can be used to move back into a damaged environment after bootstrapping from an alternate root file system. Elevated Privileges in iptables are required for operation, and root user must be used or iptables will not function. With most Linux systems, iptables is installed as /usr/sbin/iptables and documented in its man page, which can be opened using man iptables. There is a set of user interface tools that can be used to manage your system’s security profile in a more user friendly manner. The user interface firewall management tools include Bastille, and GUI tools with like KDE’s Guard dog. There are Linux distributions whose main purpose is to provide a GUI front end to iptables with a variety of configurations. Iptables allows the system administrator to define tables containing chains of rules for the treatment of packets. Each table is associated with a different style of packet processing. Packets are processed by sequentially traversing the rules in chains. A rule in a chain can cause a goto or jump to another chain, and this can be repeated to whatever level of nesting is desired and every network packet arriving at or leaving from the computer traverses at least one chain.

â€Å"Blood In†¦Blood Out† Bound By Honor.   Ã‚  Ã‚  Ã‚  Ã‚   In the movie â€Å"Blood In†¦Blood Out,† there are three young Chicano teens just trying to survive in a white man’s world. First, you have Paco, a rebellious teen that loves a fight, and is in a small East Los Angeles street gang called â€Å"Vatos Locos.† Then, there is his half brother Cruz, he is trying to stray away from the gang life by painting, however, he still is and hangs with the Vatos Locos. Lastly, with blonde hair, blue eyes, and white skin, there is Miklo the cousin of Cruz and Paco, who ran away from his white father to reconect with his Mexican roots. The only problem is Miklo does not look Chicano, and the Mexican community, including Paco, have a hard time accepting him into the world he so much wants to be a part of. His friends call him names like â€Å"white boy† or â€Å"guero† to make fun of his skin. Miklo though, is determined to gain the respect of his peers, he decides that he too wants to be a â€Å"Vato Loco,â₠¬  which doesn’t sit very well with Paco. He tells Miklo, â€Å"Do white boys get VL placas (tattoos)? No, it doesn’t happen. Unless†¦Ã¢â‚¬  and that’s where it all starts. Paco decides that his cousin can be part of the Vatos Locos, but since he is half white, he will have to prove himself to the group, by doing something big for them. Miklo quickly obliges, and bashes out the window of a rival gang called â€Å"Tres Puntos.† With that Miklo gets to be in the â€Å"in crowd† as he always wanted to be. Tres Puntos not agreeing with this, takes it out on Cruz, and thus starts a gang war. Things become even worse when at a war between the two gangs, Miklo shoots and kills the head member Spider. This brings on even bigger problems then Miklo can imagine: San Quentin Prison. Suddenly, everything Miklo learned in the street gang becomes obsolete, and he is back to being an outsider with no one to turn to. The AV’ers, a clique of white males in prison, want Miklo to side with them, but Miklo does not want any part of them. Instead, he wants to hang with the Mexican clique, La Onda, which do not want anything to do with this â€Å"guero† (white boy in Spanish). They pick on him, call him names, and do not want him within their sight.

Definition paper on the word “Strength” Essay

Strength is more then just a physical word. It is a word of high stature. Strength can be used in three ways; physical, mental, and spiritual. Strength is the quality of being physically strong, capacity to sustain the application of force without yielding or breaking, effectiveness, and concentration. Strength is a word that is a greatly misinterpreted from time to time. To some, strength is only in physical form, but for others strength comes with emotions and spirituality. Physical strength is a good thing to have for your personal benefit. To be physically fit is good for your health and for the protection of you and others. To have physical strength is a great asset, but for some a mere burden. For the bully who abuses his physical strength, it could lead to anguish and pain for him and others. Is a man strong when he hits his wife or is a man strong when he offers comfort? That’s were mental strength comes into play. Mental strength can be one of the best things to have. To be able to control a situation is a great thing. When we get older we gain more mental strength, because our minds gain more knowledge. Karate teaches self defense, but their main focus is on mental strength. The instructors  teach their students to only use karate as self defense. That it takes more strength to not use karate then it does to actually use it. In a relationship mental strength is the top quality. â€Å"It takes a lot of mental strength to focused and stay married for twenty-nine years.†(John Hart) Teaching anything and everything involves a lot of mental strength (patience). For some having attractive features can lead to over confidence, niaveness, and broken relationships. For others having beauty is not taken lightly and put it to good use by being faithful to their mates which takes mental strength by choosing not to be a rover. Spiritual strength takes a lot of self assurance. Strength in the religious world comes from within. Faith and trust are the strong reminders for those in their beliefs. Is a pastor strong because he stays in a church that is conspiring against him and lost their ability to hear the word of God through their Pastor, or is he strong when he chooses to leave? I would have to say that a Pastor has to be wise and listen to God telling him its time to go and be a fresh voice to others. It takes strength to discern from what the Devil wants us to believe and the truth. Spiritual strength can come in hard times as well as good. Consider a mans thoughts when he suffers a tragic fall and becomes a paraplegic and has to spend the rest of his life looking up to short people, having to ask for the simplest of help (wheel chair getting stuck in a small hole), or simply having to behave or else. Spiritual weakness can come in the form of  cursing God for our misfortune and asking him why Spiritual strength is accepting that the Bible tells us there is a reason for all things. To some spiritual strength is doing good deeds and keeping a record of them. I have seen people of strong spiritual strength who never seem to waiver in challenging times. Job was a man of spiritual strength and I know personally I would not want to suffer as much or the way he did. Job was a man of all three strengths, physical, mental and spiritual.

The Shutdown Of Public Mental Health - 1614 Words

In recent years, evidence and studies have proven that the shutdown of various mental health facilities across the nation has caused a dramatic increase in the number of incarcerations for people who suffer from mental illness. In 2006, the Bureau of Justice Statistics calculated that there were approximately 705,600 mentally ill adults incarcerated in state prisons, 78,800 mentally ill adults incarcerated in federal prisons, and 479,900 mentally ill adults incarcerated in local jails (â€Å"Mentally Ill†). In response to the increase in the number of incarcerations and news stories, people around the nation developed harmful stigmas towards mentally ill people. According to Sarah Glazer’s article entitled Prisoners and Mental Illness, the state governments do not allocate enough spending to mental health care. In the hopes of reducing funding and saving money, many state governments across the nation forced the shutdown of public mental health facilities, which led to an increase in crimes committed by mentally ill people. According to Dr. Marie E. Rueve and Dr. Randon S. Welton’s article entitled â€Å"Violence and Mental Illness†, society believes that mentally ill people are worthless and violent, which is a negative impact of the increase in crimes committed by mentally ill people. In response to the stigma created by society, many people believe that the mentally ill deserve incarceration in order to keep them from harming other members of the community.

Sonnet 29 Essay Example For Students

Sonnet 29 Essay Word Count: 370Sonnet #29Despite popular belief, William Shakespeare was considered a great poet before a great playwright. He accomplished writing at least 154 sonnets and other poems of love. In this paper, I will analyze one of his greatest sonnets. One of the most famous of his sonnets is number XXIX. This sonnet is one long sentence, but it still follows the usual Shakespearean pattern of three quatrains (four line sections) and a couplet. It also follows the traditional rhyme scheme for Shakespearian sonnets: ababcdcdefefgg. The first quatrain tells how the narrator is feeling. From reading these four lines, you sense his loneliness and sense of abandonment by fate, G-d, love, and other men. I believe the key line in this quatrain is line 3 (When, in disgrace with fortune and mens eyes,). Here I feel Shakespeare is saying that this person who isvery depressed, is crying out for help to others, but he is such an outcast that not even deaf heaven, meaning God and the angels of heaven or listening to his cries. The second quatrain starts off with a line that shows the narrator wishes to be more optimistic. He realizes that in order to achieve his goals, he must believe in himself first and stop being so depressed. The second half of the quatrain shows he is envious of other mens possessions and riches when he says, Desiring this mans art and that mans scope, With what I most enjoy contented least. Moving into the third quatrain, you see that the speaker begins to reflect on himself and starts to compare himself with his friends. You know this when Haply I think on thee, and then my state, is said. Just as you start to think the speaker is going back into a state of self-pity, you realize the speakers inspired sprits are rising like the lark at break of day. Sonnet XXIX ends with a couplet that has an uplifting message. One the speaker remembers the love of his friend and what great things he has, it makes him happy with his life. So happy he wouldnt even consider swapping his place with a king.
