Whisper of Aids
Samantha Blum Comp 1 Mrs. L-P 20 January 2012 ââ¬Å"The Whisper of AIDSâ⬠is an incredible discourse. Mary Fisher composed an extremely powerful discourse; one that would change a great deal of Americanââ¬â¢s sees on AIDS. This discourse activated feelings and delivered an issue once in a while discussed in that season of the world. Mary Fisherââ¬â¢s central matter was to freed the generalizations of individuals who gotten the explicitly transmitted malady, AIDS. Fisher was a Caucasian female. She was not poor, not African American, and not gay. She didn't contract AIDS from being with numerous accomplices; she got it from her husband.Fisher needed individuals to realize that AIDS can transpire. In her discourse she stated, ââ¬Å"It [AIDS] couldn't care less whether you are Democrat or Republican; it doesn't ask whether you are dark or white, male or female, gay or straight, youthful or old. â⬠In this discourse, she was conversing with the Republican National Conve ntion. By looking at the two totally different ideological groups (Republicans and Democrats), it shows that genuinely anybody can be survivors of this ailment. Fisher truly made individuals think when she expressed, ââ¬Å"Though I am white and a mother, I am unified with a dark baby battling with tubes in a Philadelphia hospital.Though I am female and gotten this sickness in marriage and appreciate the warm help of my family, I am unified with the forlorn gay man protecting a glimmering flame from the virus wind of his familyââ¬â¢s dismissal. â⬠She utilized a strategy known as ââ¬Å"pathosâ⬠, which is utilizing feelings to persuade a group of people in what you are stating. By an ordinary lady contrasting herself with the commonplace generalizations of AIDS, Fisher opened eyes about this sickness. Numerous individuals thought just African Americanââ¬â¢s could contract AIDS in light of the fact that the sickness is supposed to be begun from Africa and the infectio n was notable there. Fisher was known to be very wealthy.This likewise helped individuals acknowledge itââ¬â¢s not simply the poor it can happen to. Fisher additionally discussed President Bush Sr. ââ¬â¢s family supporting her through this time. This is intriguing in light of the fact that Republicans are known as the ââ¬Å"conservativeâ⬠party versus the Democrat party, so normally democrats would have been bound to acknowledge AIDS scourge. I trust Fisher raised President Bush to make Republicans progressively open to the possibility of ââ¬Å"normalâ⬠individuals contracting AIDS. At the point when Fisher told individuals from the earliest starting point that she got gotten her STD from her significant other, she was consequently thought of as honest.It was beneficial for her to be known as fair since then the crowd confided in her and truly put stock in what she needed to state. Fisher utilized tenderness commonly in this discourse. At the point when she began d iscussing her family, she truly hit home to numerous Americans. Each and every individual who had youngsters could identify with her by then. She expressed, ââ¬Å"My child Max, presently four, will take the proportion of his mom. My child Zachary, presently two, will figure out his recollections. I may not be here to hear their decisions, yet I know as of now what I trust they are. I need my youngsters to realize that their mom was not a victim.She was an envoy. I don't need them to think, as I once did, that boldness is the nonattendance of dread. â⬠In my supposition this was the most contacting piece of her discourse. Discussing her youngsters was extremely passionate to peruse and by her expressing that she probably won't be there to hear her decisions caused individuals to understand that this malady is not kidding and destructive. Her last articulation, ââ¬Å"To all inside the sound of my voice, I bid: Learn with me the exercises of history and of elegance, so my kids w on't be hesitant to state the word ââ¬Å"AIDSâ⬠when I am gone.Then, their youngsters and yours should not have to murmur it by any stretch of the imagination. God favor the kids, God favor every one of us. Goodnight. â⬠demonstrated America that AIDS isn't something to be embarrassed about and not something that should be covered up. Mary Fisher worked admirably at affecting peopleââ¬â¢s contemplations about AIDS. In this time and day, AIDS is notable and itââ¬â¢s not something individuals are humiliated to discuss. She made it her objective to tell individuals AIDS can happen to anybody and cautioned individuals to be wary of it. Fisher changed the lifeââ¬â¢sââ¬â¢ of numerous and what we look like at AIDS today.

How important is an intellectual property right (IPR)? IPR protects the creator or inventorââ¬â¢s benefits, so that it stimulates the interest of innovation. According to United States Patent and Trademark Office (USPTO), the number of patent application has been increased over 450% from 1980 to 2010. It shows that people now are more concern about copyright issues. Although owners have the patent application, the violating of copyrights and patents are still happening all over the world.

Exploration Of Oil And Gas Resources Essay - 1715 Words
Introduction With the continued depletion of conventional oil and gas resources, the oil industry is now more than ever faced with exploration of unconventional and challenging oil and gas reserves. Such reserves call for novel drilling techniques and also require drilling fluids that can fulfil such drilling requirements. In most cases itââ¬â¢s OBM that can provide hole stability and it is also the best choice for drilling highly sensitive wells. But as these OBMs are being used, operators must strike a balance between their desired high performance standards and environmental concerns of their regulators and local communities. These stringent environmental concerns have led to research and development of many water based drilling muds but these muds still donââ¬â¢t offer the desired drilling performances like OBMs. We shall now look at the advantages and disadvantages of both OBMs and WBMs Advantages of WBM: WBMs pose a comparably minimal risk to the environment, thereââ¬â¢s a lower logistical challenge as compared to OBMs in terms of transporting of the liquid phase, For WBMs disposal doesnââ¬â¢t require high transportation cost like OBMs especially for off shore operations that might require shipment to shore for treatment and disposal, Viscosity and Density are easily controlled, for low pressure formations, WBMs are a good choice, easier removal of drill cuttings at shakers and Less of a need for cuttings washing and drying.

The World Wide Web Free Essays
string(64) " stream between LDAP client and the server \(Sheresh B, 2001\)\." Introduction The World Wide Web makes available so much information; only unfortunate is the fact that there were no tools to query such information to its fullest extent. The world needed an acceptable method for searching for and using resources over computer networks. Resources may take the form of computers, businesses, schools and users hence a Directory Access protocol. We will write a custom essay sample on The World Wide Web or any similar topic only for you Order Now A directory is a huge collection of well organized and indexed records or specialized databases that are optimized for a direct lookups (Barber B., et al. 2009). Some directories that can be accessed by LDAP server include the Active Directory (AD) and the Domain Name Service (DNS). The Directory services are categorized into two distinct groups; the local service and the global service group The local service has its service on a single machine while the Global service however has its data spread across many machines and provides its service on a bigger and broader scale that is to the World Wide Web. All these directories on the global directory services cooperate to provide the directory service. A typical example of this global service group is the Domain Name Systems. LDAP as an acronym for Lightweight Directory Access Protocol is a series of interconnected databases located in different locations on the internet and is an open standard lightweight version of a Directory Access Protocol. It is a protocol that runs over TCP/IP protocol and its data is optimized more for reading than for updating. The way of getting out this structured information from diverse sources in an efficient manner is what LDAP concerns itself about. LDAP is based largely on Directory Access Protocol. The Directory Access Protocol is designed for communication between directory servers and clientââ¬â¢s complaint to the x.500 standard. The X.500 standard defines a protocol for a client application to access the X.500 directory. The X.500 directory service is an LDAP-enabled directory service that provides the capability to look up and search for information almost like the yellow pages services (Nancy, C., 2003). DAP is one of the X.500ââ¬â¢s directory client access protocols that supports the search and lookup feature of the X.500 but DAP had some performance problems. Some problems of the DAP includes the size. The DAP was very large, complex and difficult to implement (Howes, T., et al, 2003). The LDAP was then introduced as it is faster and simpler without the performance problems DAP posed. The LDAP is based on a client-server model. In this system, there are LDAP servers that host public directory service and the clients that connect to the LDAP servers to search for results. LDAP clients are inbuilt into many address book applications today including some email clients like the Microsoft outlook. The Lightweight Directory Access Protocol employs the following operations. 1. Binding to server 2. Searching for an entry 3. Comparing entries 4. Adding an entry 5. Modifying existing entries 6. Removing an entry Of all the operations LDAP deploys, the binding process is the one that involves authentication and it is here that LDAP security becomes of much value. An LDAP client initiates a connection with the LDAP server by sending a bind operation. This bind request may contain the user authentication information. 1. LDAP SECURITY FEATURES This bind feature is captured under the security model of the LDAP models and it provides a mechanism for clients to authenticate themselves before they can access data from the LDAP server (Howes T., Smith, M. 1997). It is commonly done with the use of userID and password logons. The knowledge of these authentication credentials guarantees that the user is indeed genuine since LDAP is a connection-oriented, message based protocol (Carter, D. 2003). The number of times a login attempt can be made is totally configurable. The diagram shown below shows the process of binding to the server in much clearer view. Figure i (Adopted from: http://technet.microsoft.com/en-us/library/ee690469.aspx) The process whereby an LDAP client is authenticated by the LDAP server is known as BINDING(David, N., et al 2001). When a client is successfully authenticated, he is allowed access to the server based on his authentication privileges. T he different kinds of authentication includes Anonymous Authentication Basic Authentication Authentication over Transport Layer Security. Authentication via Secured Socket Layer Simple Authentication and Security Layer Access control List 1.1 ANONYMOUS AUTHENTICATION It is noteworthy to say that the Lightweight Directory Access Protocol supports anonymous access. This means anyone can have access to information provided by the LDAP server for some applications without the need to provide a DN and password. A DN is a unique name for an entry in the LDAP directory services. An LDAP server authenticates a user as anonymous if a bind operation is not sent with an initial bind operation. So, for security reasons, the ldap anonymous authentication should be disabled. An anonymous authentication feature can be disabled with the ââ¬Å"disallow bind_anonâ⬠parameter (Carter, G. 2003). Figure ii. Screenshot of an openldap anonymous authentication. 1.2 BASIC/SIMPLE AUTHENTICATION The basic authentication is sometimes referred to as simple authentication method and it is a kind of authentication system used by web browsers like the internet explorer, Mozilla Firefox, Netscape web-browser and some client based application programs to connect to the server. This kind of authentication sends authentication credentials across to the LDAP server in clear text. These credentials usually take the form of a user authentication like the username and password. This type of authentication system is vulnerable to potential exploiters as the unencrypted authentication data is sent in the clear. Figure iii : Screenshot of a basic simple authentication. Obviously, an authentication method that will not permit eavesdropping is required. The developers then chose to incorporate an authentication framework called Simple Authentication and Security Layer ââ¬â SASL (Howes T. et al, 2003). 1.3 SIMPLE AUTHENTICATION AND SECURITY LAYER The SASL is a powerful means of providing secure communications using Kerberos and a variety of other methods in LDAP v.3 by encrypting the entire data stream between LDAP client and the server (Sheresh B, 2001). You read "The World Wide Web" in category "Essay examples" The SASL option is needed when a The LDAP server provides a set of supported authentication mechanism and the client decides which of them to use. It is the mechanism that describes the flow of information that needs to occur to support a particular authentication method. (Howes T et al, 2003). Some of the mechanisms includes the Challenge-Response Authentication Mechanism Message Digest 5 (CRAM-MD5) ââ¬â This is an algorithm which uses MD5 hash for client authentication, GSSAPI ââ¬â This supports Kerberos authentication, SKEY ââ¬â This employs a Message Digest (MD4) algorithm. Kerberous_v4 ââ¬â which involves a Kerberos encryption algorithm (Anderson R. et al. 2002). With this more secured basic authentication, the message transfer is encrypted all through the server-client data exchange. Microsoft Windows NT LAN Manager (NTLM) ââ¬â The NTLM is simply an authentication protocol like the Kerberos that improves authentication, integrity and confidentiality to users by hardening protocol against many spoofing attack. It is a challenge-response authentication protocol (Lefkovitz W., Wade W., 2001) that ensures that a user is indeed who he says he is by answering correctly the challenge that the LDAP server generates in three steps. * Negotiate_Message * Challenge_Message * Authenticate_Message. 1.4 AUTHENTICATION OVER TRANSPORT LAYER SECURITY This mode of encryption and authentication is closely related to the SSL, a Secure Socket Layer encrypts the data connection over which a simple password is transmitted. This protects data from packet sniffing by anyone with physical access to the network. SSL uses a certificate-based method for an SSL security to work. Like SSL, TLS also uses a certificate-based method of authenticating users. TLS provides proof of a server identity and protection of data in transit. The Access Control list is also a security feature supported by LDAP and this prevents data from being seen and modified by unwanted people. Figure iii showing TLS 1.5SECURED SOCKET LAYER SECURITY FEATURE This is an LDAP Administration and security tool developed by Netscape for creating secured connection between a client and server over the internet using port 636. According to Bialaski T et al,(2001), a secured LDAP connection is accomplished from client-side SSL. This mode of authentication is based on issuance of signed digital certificates from trusted authorities. In accordance to Bialaski T.,(2002), the mechanism for identity using SSL is the digital certificate. Figure iv LDAP client ââ¬â server binding using SSL (Adopted from: http://sqltech.cl/doc/oas10gR3/core.1013/b25209/ssl_intro.htm). The two aspects of security using SSL are the identification and the encryption 1. Identification. ââ¬â It checks to make sure that the client is indeed genuine by checking the digital certificates. 2. Encryption. ââ¬â Encrypts data sent from one the client computer to the server and it is a security tool uses a secured TCP/IP port 636. 2. ACCESS CONTROL SECURITY FEATURE OF LDAP. An Access Control List is simply a list of permissions attached to an object (Reisman, B. and Ruebush, M., 2004). As the directory gets populated with data of varying importance, controlling the kinds of access to the directory and records in the directory becomes more vital. Permission as to who has a read, write or no access at all is used to grant or refuse a user or group of users (OU) a specific action (Reisman, B. and Ruebush, M. 2004). Each entry in a LDAP directory contains a special set of attributes which describes who is allowed access information within that entry denoted by DN. Distinguished names. The type of access granted a user determines the operations that can be performed. Most LDAP servers provide a set of access levels operations such as: ââ¬â Add an entry ââ¬â Delete and entry ââ¬â Access an entry ââ¬â Read an attribute ââ¬â Modify an attribute ââ¬â Search an attribute. An LDIF (Lightweight Directory Interchange Format) is a plain text data interchange format for representing LDAP directory content. It used mostly to construct a directory information tree, add an entry into the ldap directory, Delete an entry, export a directory and edit a directory (Zytrax, 2008). According to Carter G. (2003), The slapd.conf file is the central source of configuration information for the OpenLDAP standalone server (Slapd) The slapd,conf is the configuration file for slapd which is a stand-alone LDAP daemon that handles the connection management, access control and protocol interpretation. The configuration file is found in the /etc/openldap/slapd.conf. It is screenshot and displayed below. Figure v: Screenshot of anonymous user authentication in slapd.conf file Figure V above allows authenticated users to change their own passwords. Allows un-authenticated users to authenticate and prevents all other access to the user Password and it permits read access to everything else. 2.1SECURITY AUDITING FEATURES FOR LDAP As a network grows, it experiences a huge flow of user logons and even huge security problems. As an administrator, it is important to monitor the LDAP server activity The directory server comes with three types of log files. Access logs, Error logs and audit logs. ldap logging option in slapd.conf logs to a slapd-log file when configured. The type of information we require slapd-log to store is defined in the level option in slapd.conf file and it represented by a number which is shown in table 3.1 below. -1 Log all information 0No logging 1Trace function calls 2Packet-handling debugging 4Heavy trace debugging 8Connection management 16Packets sent and received 32search filter processing 64Configuration file processing 256Statistics of connections 512Print entry debugging Table 3.1 OpenLDAP logging levels Analysing the /var/log/slapd-log file gives a good idea on what kind of entries are being searched as well as the frequency of access on the ldap server. The downside to this is that the logfiles get very bulky with time. 2.2BRUTE-FORCING IN LDAP According to Radhamani, G. and Radha K. (2007), a brute force attack is a method of defeating an authentication scheme by trying very many possible combinations. The syslog is an essential tool in logging system events. When a user attempts an invalid logon attempt, the event is logged. Bruteforce attack login attempts are no different as they are conspicuous on the syslog file because multiple unsuccessful login attempts will be made.. To decrease the chances of a successful brute force login attack, the following steps should be taken. Length of authentication characters should be increased. : The user authentication credentials should be made more complex. The higher the number of characters in The I.P address from which the brute forcing is done be locked out after a certain period of attempts. Delay timing is implemented in between failed authentication attempts. CONCLUSION A directory, being a collection of well organized and indexed records optimized for direct lookups (Barber, B. et al. 2009) are very essential to our everyday information sourcing. It therefore requires that the records in this directory be secured. The following options list methods that can be employed for these records to be secured. Ensuring a secured communication between the LDAP client and server to checkmate sniffing. Access control listing must be configured properly and double checked for complexities in its setup that may lead to a loophole in ldap security. Login activities must be logged. Once these security features are put in place, the world of a more structured information sourcing would be a better place.

Hail to the King by Avenged Sevenfold free essay sample
After a three-year hiatus, Avenged Sevenfold is back with their long-awaited album ââ¬Å"Hail to the King.â⬠Rather than trying to reinvent the wheel, the group decided to strip things down and go for a simpler approach, a major risk in the music industry. However, their efforts were not in vain, as ââ¬Å"Hail to the Kingâ⬠may just be Avenged Sevenfoldââ¬â¢s best album to date. Diehard fans wonââ¬â¢t be disappointed, because while the band has gone for a simpler, harder rock feel, every element of their style has been maintained. The album kicks off with ââ¬Å"Shepherd of Fire,â⬠featuring a slow, almost orchestral opening, followed by the classic Sevenfold style fans have come to love. From there, things only get hotter with the title track, ââ¬Å"Hail to the King.â⬠ââ¬Å"Doing Time,â⬠ââ¬Å"This Means War,â⬠and ââ¬Å"Requiemâ⬠follow, each presenting a variety of riffs, rhythms, and guitar solos sure to induce instant head-banging.

This stands out ââ¬â the lyrics are beautiful and the overall feel is somber and almost sweet. Then the album spirals back to classic Sevenfold with ââ¬Å"Heretic,â⬠ââ¬Å"Coming Home,â⬠and ââ¬Å"Planets.â⬠As with the first four songs, each is varied yet maintains Avenged Sevenfoldââ¬â¢s style. At the last spot on the album, but far from the least, we have ââ¬Å"Acid Rain.â⬠This track will turn the heads of most listeners. Instead of embracing a hard-rock vibe, ââ¬Å"Acid Rainâ⬠is a slow, piano-based song. While itââ¬â¢s not the style Sevenfold fans have come to know and love, itââ¬â¢s beautiful and more than worth spamming the replay button for. ââ¬Å"Hail to the Kingâ⬠had monumental standards to live up to, especially after the long wait. However, it far exceeds all expectations from the moment you hit the play button. Every track is a new piece of amazing music, from the heavy-riff-based ââ¬Å"This Means Warâ⬠to the melodic and orchestral ââ¬Å"Requiemâ⬠and the gorgeous ââ¬Å"Acid Rain.â⬠Avenged Sevenfold has created another musical masterpiece; ââ¬Å"Hail to the Kingâ⬠deserves every bit of praise it receives. I strongly recommend it to any Sevenfold fan, or rock fan in general, as the variety will appeal to all kinds of audiences. This is an absolute must-have.
