Securing and Protecting Information Essay Example for Free

Securing and Protecting Information Essay The specific purpose of this paper is to describe the authentication process and to describe how this and other information security considerations will affect the design and development process for new information systems. The authentication process is a necessity for safeguarding systems against various forms of security threats, such as password-cracking tools, brute-force or wordbook attacks, abuse of system access rights, impersonation of attested users, and last but not least reply attacks just to name a few. In addition, it is imperative that authentication policies are interchangeable with the organizations in which information is being exchanged if resources are being shared between alternative organizations. Authentication in definition is simply proof that something is real or what it is meant to be. Public networks as well as private networks to include the internet use passwords as authentication to authorize logins. Data is required and is filtered through the password database if an effort to ensure that the user is authentic. Also, before anyone is allowed to access an organization’s intranet they must first be registered by someone that has the appropriate credentials to authorize them to gain access. There are plenty of businesses and alternative in the need of additional authentication methods and one method worthy of mentioning is the utilization of digital certificates issued and verified by a Certificate Authority or as commonly used the acronym CA. This process includes the creation of a strong password and an account lockout policy is created, logon hours are assigned, a ticket expiration policy is created, and clock synchronization tolerance to prevent replay attacks is set just to name some of what this process consist of. There are some things that must be taken into  consideration when a new system is design. Securing and Protecting Information When a team is appointed to designs a new system, that team must understand that all systems are not the same and that they all have their own unique attributes in their own way but the thought process must be the same in regards to security. It is quite challenging to insure that the application integration setting functions properly in a way that does not compromise the security needs. Security is especially necessary in applications that require systems in a company to be streamlined. Integration services might lead to security breaches because of the integrated systems and the holes that may exist during the integration process. To try to alleviate this from occurring, data security should be integrated into the System Development Life Cycle (SDLC) from its beginning phase. This focuses directly on the knowledge security sections of the Syetsm Development Life Cycle. First, an outline of the key security roles and responsibilities should be addressed to insure that everyone involved knows what is expected. Second, ample data concerning the System Development Life Cycle is provided to permit anyone who is unfamiliar with the System Development Life Cycle method in order that they may grasp the connection between data security and also the System Development Life Cycle There are several ways exist that could be employed by a corporation to effectively develop a data system. A conventional System Development Life Cycle is known as a linear sequent model. The linear sequent model assumes that the systems are going to be delivered at a point near the top of its life cycle. Another SDLC technique uses the prototyping model that is commonly accustomed to development and understanding of a system’s needs while not really developing a final operational system. Complicated systems need continuous additional constant development models. Securing and Protecting Information Information system policies address security threats that may be harmful to a company. Sadly, there is no way to alleviate the numerous amounts of threats that haunt networks and computers worldwide. The foundation and framework for choosing and implementing countermeasures against them are very important. A written policy is vital in helping to  insure that everyone within the organization understands and behaves in an appropriate manner with regards to the fact that sensitive data and the security of software should be kept safe. When a security policy is developed, it should be well defined and the information in it should be clear and plainly understand and the objectives should be well defined so that there will be no confusion. Conversely, a data system with security policies is probably going to have an assortment of countermeasures that address a range of threats. Policies, standards, guidelines, and coaching materials that are known to be obsolete and not enforced could be dangerous to a corporation due to the data being outdated. As a result, management is basically drawn into thinking that security policies do exist within the organization when actually that is not the case. Counter measures which are outdated does not do an organization any good because without the appropriate patches in place, the organization’s network could have holes which would leave them extremely vulnerable. All organizations need to be compelled to actively put their security systems to the test and in addition they could even go as far as hiring an outside firm to ping the system to see if any holes appear that could leave the company’s system vulnerable. Of course there are preventive roles and measures that could and should be taken. Data security should be a crucial area of concern for small business owners. Knowledge of security compliance is no longer merely an area of financial concern Securing and Protecting Information As more and more data moves out of the file cabinet and into the electronic space, Information Technology departments will play an integral role in complying with all of the security policies. Once you take into account all the necessary information stored from economic records to customers data, it is not difficult to discover why only a single breach could seriously affect a business. With a number of basic steps and a few sensible on-line habits, youll prevent yourself from turning into simply another victim of cyber crime. (Ratha, Connell, Bolle, 2001) Some of the preventive roles and measures mentioned above are as follows: implementing sturdy strong passwords, use a mixture of capital and lower-case letters, symbols, and numbers and create it eight to twelve characters long, acquire  anti-virus/anti-malware software package, and last but not least, ensure your personal computer (PC) is properly patched and updated. It is important to mention that there is very little purpose in installing a very effective software package if it is not going to be properly maintained. As Watchinski explains, â€Å"while applications arent 100% fool-proofs, its necessary to frequently update these tools to assist in keeping users safe. It is also worthy of mentioning that scheduling regular backups to AN external drive, or within the cloud, may be painless thanks to make sure that all of your knowledge is kept safely. It must also be mentioned that it is not uncommon for an unsuspecting worker to click on a link or transfer an attachment that they believe is harmless just to realize later that the link contained malicious software that has compromised the company’s network. It is extremely important to teach your staff to practice safe on-line habits and beieing proactive with defense is crucial. Employees have a crucial role to play to keep your business and its knowledge secure. Securing and Protecting Information To touch on systems and devices in reference to security, security refers to providing a protection system to ADPS resources such as the central processor, memory, disk, software package programs, and most significantly data/information keep within the ADPS. As a part of the data systems security management, there are square measures peripheral devices installed so that the regulated community so to speak will listen. These peripheral devices will create an unseen threat (insider/third party threat). (Workman, Bommer, Straub, 2008) There are certain devices that appear to be harmless but could prove to cause issues such as USB devices (commonly known as flash/thumb drives), USB patch cords with mini/micro connectors, and Electronic notebooks just to name a few. In conclusion, security authentication is extremely necessary and relevant in the protection of an organization’s information.

Grandpa - The Life of a Golfer and Great Man :: Biography Biographies Essays

Grandpa - The Life of a Golfer and Great Man As I got to know my husband's family, I knew golf was the one thing I eventually was going to have to learn. To them golf is more than just a sport, it is a way of life. Every summer they gather on the golf course for at least one round of golf a week and it always made me wonder, what is it about the game that has got them this hooked? Is there something about it I am just not getting? Every holiday, birthday or major occasion, there is always someone who will happily accept any gift related to golf. So one day, I began to ask questions, and eventually I found out the person they have to thank for this wonderful vice is Grandpa Luke. Luke Sutton is an 80 year old man who has played many roles. As you see him standing on the green, you see a man covered with the suntan of many summers spent outside playing golf. You see big rough hands, worn down from years of factory work, and the grey hair and many wrinkles he has earned. But you also see the twinkle in his eyes and the great big smile on his face that always invites you to come and talk with him for a while, since he has many stories to tell. I would like to tell you the story of how he became the golfer that he is, since it is an accomplishment of his no one knows much about. Luke Sutton was born in 1915 and grew up during the Depression Era in Henry, Illinois, a small suburb of Chicago. At age 9 he and his older brother found jobs as caddies at the Ravisloe Country Club. He was two years younger than the age limit for caddies, but he persuaded management to allow him to caddie for the ladies in the club. He was such a small boy and their golf bags were not as heavy as the men's golf bags. He was paid one dollar for each round played and when it was time to go home, he would walk the four miles back home. "Don't break the dollar for bus fare," his mother would say. It was a rough time financially and every little bit helped the whole family. It was through caddying that he developed his love for the sport.

Review of Mobile Presence Services in Social Network Applications

REVIEW ON MOBILE PRESENCE SERVICES IN SOCIAL NETWORK APPLICATIONS Abstraction—Today broad scopes of nomadic devices are available. As the use and engineering of nomadic devices additions, societal web applications are going popular. An indispensable constituent of this societal web application is nomadic presence service, which maintains each nomadic user’s presence information. The presence information means the current position, GPS location of nomadic user and besides updates the user’s online friend’s information. As the update occur often, figure of message distributed by presence waiter may take to scalability job.To specify this job, scalable waiter architecture called PresenceCloud is defined.In cosmopolitan nomadic telecommunication system ( UMTS ) , the presence service is performed by IP multimedia nucleus web subsystem ( IMS ) .A weak consistent scheme is used to cut down the presentment traffic. Presentment clip means clip needed to advise the presence information to other users. This paper makes a reapprais al on work outing buddy list hunt job.The consequence shows that PresenceCloud achieves public presentation addition in the hunt cost without compromising hunt satisfaction. Keywords—social web ; nomadic presence service ; presence information ;I. IntroductionMobile computer science is human-computer by which a computing machine is expected to be transported during normal use. This involved nomadic communicating, hardware etc. Chiefly nomadic calculating describes about communicating among client to server, client to other terminal user, waiter to server etc. Today as the engineering and use of cyberspace additions, societal web application/services ( illustrations are Facebook [ 1 ] , Twitter [ 2 ] , buddycloud [ 3 ] , Google latitude [ 4 ] , foursquare [ 5 ] ) go popular in worldwide. Many communications like confab, online concern, informations sharing etc can be done utilizing societal web application/services. Hence, it is inevitable that societal web services will be the following coevals of nomadic cyberspace application. Mobile presence service is one of the of import component in societal web application. Mobile presence service means maintain up-to day of the month presence information of all nomadic user. Presence information includes location, position, activity etc about the nomadic users. Each nomadic user has a list of friend’s list which we can name as buddy list. On the other manus, we can state that buddy list contains the contact information of the user he/she needs to pass on. Each nomadic user in the societal w eb application gets information about their on-line friends/buddies via the presence information. The nomadic user’s position is broadcast automatically to the buddy list whenever the user moves from one position to another. So presentment is an of import portion in societal web application. Most presence services use server bunch engineering, to maximise hunt velocity and minimise the presentment clip. The waiter involved in this communicating, keeps up-to day of the month path of all these presence information sing the nomadic user. There are so many issues in nomadic computer science. Some are deficient bandwidth, require careful usage of practical private web, cell phone signals may do wellness jobs, signal jobs during going, more power ingestion during less signal strength etc. In cosmopolitan nomadic telecommunication system ( UMTS ) , the presence service is performed by IP multimedia nucleus web subsystem ( IMS ) .Here a weak consistent scheme is used to cut down the presentment traffic. Hence presentment clip can be cut downing. Presentment clip means clip needed to advise the presence information to other users. Instantaneous message provides communicating ( online confab ) between two or more users over cyberspace. Microsoft courier, yahoo courier are some of the illustrations for the instant message. Overview of the available characteristics, maps, architecture, protocols used in these popular populace IM web are described. Besides discuss advantages and disadvantages of these IM webs. In societal web application an efficient and scalable server-to-server sheathing architecture called PresenceCloud is used to better the efficiency of nomadic presence services for large-scale societal web. A quorum-based server-to-server architecture is used for efficient buddy list seeking. The comparing consequence shows that PresenceCloud achieves public presentation additions without giving hunt satisfaction. Search satisfaction is defined as the clip it takes to seek for the geting user’s buddy list.II. Different engineeringsThis subdivision describes assorted method or engineerings used in different systems. Here, foremost describes about different characteristics and maps supported by three most popular IM systems: AIM, Microsoft MSN and Yahoo! Messenger. Second describes, in cosmopolitan nomadic telecommunication system ( UMTS ) web architecture, to cut down the presentment traffic a decrepit consistent strategy called delayed update can be used. Third describes about chord which provide a scalable peer-to-peer search service for internet application. Finally, an efficient and scalable waiter architecture called PresenceCloud is defined. In [ 6 ] describes different maps and characteristics of three IM systems such as AIM, Microsoft MSN and Yahoo Messenger. Instant messaging can be specify a public confab etc. In extra some provide file transportation, webcam use, voice confabs session etc. Here the writer comparing three IM systems ( AIM, Microsoft MSN and Yahoo Messenger ) .All of these IM systems uses client-server architecture. Supporting immense figure of user is an of import issue in these IM systems. Two methods are available: 1 is symmetric and other is asymmetric. Each waiter performs indistinguishable maps in symmetric method and in asymmetric method each waiter execute peculiar activity assigned to it like log in, detecting other users, maintain chat room etc. For normal operation AIM uses client-server architecture and for voice confabs session uses peer-to-peer attack. Therefore two clients communicate straight without utilizing a confab room. For normal and voice confabs YMSG uses client-server architecture. Through centralised voice chat server YMSG voice traffic is routed. One advantage of utilizing this attack is that within the same confab room it can back up multiple users and each user can stipulate their ain voice specification. For normal operation MSN uses client-server architecture and for voice confabs session uses peer-to-peer approach.MSN voice chat session is limited to two individuals. Most of the IM systems have techniques for keeping list of friends. They are called buddy list, allow list and block list. Buddy list contain peoples that a user demand to pass on and supervise their presence. Block list contains peoples that a user demand to barricade communicating with them, it’s besides called black list. Allow li st contains people that a user needs to pass on. MSN, AIM and YMSG contains buddy list and block list.MSN and AIM besides contain allow list. Many web protocols like TCP and IP have used binary representation of informations in byte order. Application bed protocol ( HTTP and SMTP ) have used text-based attack. The advantage of utilizing bye order is that it supports efficient usage of infinite in the web. The advantage of text-based attack is that the representation is closer to human position information and debugging is easier.AIM and YMSG utilizations binary representation for their header.AIM contains two-level binary representation called FLAP and SNAC packages. Fixed length heading and variable length day of the month in FLAP packages. SNAC packages are subtype of FLAP packages that contains fixes length Fieldss followed by a variable information constituent. Fig.1.AIM FLAP and SNAC package format YMSG has individual degree construction for fixed Fieldss followed by variable length Fig.2.YMSG package format One of the of import job in IM suppliers are user send informations at inordinate rate, inundation caused in the web because of useless traffic.TCP provide some protection mechanism against this through congestion control.AIM has a complex algorithm for solve this, but it has different rate ( rates are based on a clip window ) bounds based on message type. The user will be warned, if the client exceeds the rate and if this continues, the waiter will get down dropping message and will unplug the client. YMSG has a bound of three IM per seconds. Another method to minimise the burden is by acquiring rid of idle clients. Each system in IM maintains a keep-alive pulse message: the connexion may be terminated if the client does non supply pulse message or response to the question. In AIM the client must direct this keep-alive message in every minute to the waiter. YMSG contains two types of pulse petition: a primary and a secondary.MSN has client and waiter pulse message. In [ 7 ] paper, to cut down the presentment traffic a decrepit consistent scheme is used. In IP multimedia nucleus web subsystem ( IMS ) , the presence waiter is responsible for advising an authorised spectator of the updated presence information. Presence service provides service to entree other user’s presence information such as the user position, activities and so on. In cosmopolitan nomadic telecommunication system ( UMTS ) web architecture, a user with user equipment entree presence service in IMS. When the user provides information to the presence waiter, so user play the function as presentity and the user accesses other user’s information so it act as a spectator. In IMS, control signaling is carried out by call session control map ( CSCF ) .The presence service process is defined by 3rdcoevals partnership undertaking ( 3GPP ) The presence waiter instantly notifies other users in the contact, when the presence information of a user alterations. If the updates occur more often, so the figure of presentment messages increases. To cut down the presentment traffic a decrepit consistent strategy called delayed update can be used. In delayed update, when the presence waiter receives the updated presence information, the presence waiter starts a delayed timer with a period T. This period is called delayed threshold. Within the period T, if the presence information is updated, so old information is replaced by the new information. When the timer expires, the presence waiter notifies the spectator of the presence information. Therefore, the presentments for the updates in T are saved. In [ 8 ] mentioned about chord which provide a scalable peer-to-peer search service for internet application. A cardinal job that challenges peer-to-peer application is turn uping the node that store a peculiar information point. This paper presents a solution for this by showing chord. The chord provides one operation: given a key, it maps the cardinal onto a node.In peer-to-peer system, the application is distributed without any cardinal control, where the package running equivalent in functionality at each node. The corresponding node is responsible for hive awaying a value associated with the key. Chord uses hashing to delegate keys to allow chord nodes. Each chord node needs merely a few other nodes routing information. Because the routing tabular array is distributed to other nodes. If N-node presented in a system, so each node maintain information merely approximately O ( log N ) other nodes. The chord maintains its routing information as the nodes articulations and leaves a s ystem. In [ 9 ] paper, an efficient and scalable waiter architecture called PresenceCloud is defined. PresenceCloud solve the scalability job called buddy list hunt job. Buddy list hunt job can be defined as the scalability job occurs when presence service is overloaded with buddy hunt message. The PresenceCloud can be used to expeditiously question the system for buddy list hunt. In PresenceCloud design, it consists of three constituents: PresenceCloud waiter sheathing, one-hop caching scheme and directed buddy hunt. When the nomadic user get into the PresenceCloud, the user authenticate to the nomadic presence service. Then the nomadic user opens a TCP connexion to one of the presence waiter. The nomadic user sends a petition to the presence waiter for buddy list hunt. PresenceCloud returns the presence information of the brothers. PresenceCloud is based on grid-quorum system ( size is vn?vn. When a presence waiter joins into the PresenceCloud, it gets an Idaho in the grid and obtains its presence waiter list. Presence server node can take one column and one row of entries. This entry is called the presence waiter list. In the fig: 3, the figure of presence waiter n=9.The PresenceCloud is arranged in grid-quorum with v9?v9 size. The presence waiter node 8 has presence server list { 2,5,7,9 } and 3 has { 1,2,6,9 } . PresenceCloud uses a hoarding scheme to retroflex presence information of each user to better the efficiency of the searching operation. Each presence server node maintains presence information of the affiliated users. When the neighbour establishes a connexion to presence waiter, the cache is updated. When a presence waiter receives a query/request from the nomadic user, it can react non merely from the lucifers from its ain list, but besides provide lucifers from its caches. Fig:3 PresenceCloud Server Overlay The figure of presentment messages increases when the nomadic user often changes its presence information. This buddy list hunt job can be solved by utilizing an algorithm called directed buddy hunt algorithm. This algorithm uses bipartisan sheathing and one-hop caching scheme. This helps PresenceCloud to supply fleet responses for big figure of nomadic user. The algorithm is defined in [ 9 ] .III. ComparisonIn mesh based design, all the presence information at each node is replicated to other nodes. Hence its hunt cost is merely one message. In distributed hash tabular array ( chord based ) , no reproduction ; presence information of a user is merely stored in one presence waiter. Here, each brother must be searched one by one. In PresenceCloud, its hunts buddy list from ain node list and cache list. Besides notifies other users about the new presence information. Simulation consequence is mentioned in [ 9 ] .This paper shows graphical representation of their consequence. Findingss from that graphical representation are: ( I ) As the reaching rate of nomadic user additions, the figure of presence message is really low in PresenceCloud. Hence PresenceCloud outperforms all other design. ( two ) As the reaching rate of nomadic user additions, the mean seeking messages/user is low in PresenceCloud. That means PresenceCloud requires least message transmittal. ( three ) Average message transmittal of PresenceCloud additions bit by bit with the figure of presence waiter. ( four ) Average message transmittal of PresenceCloud is non impacted by the figure of brothers. When analysing hunt satisfaction in waiter architecture, the findings are ; ( I ) Buddy seeking latency grows with the figure of presence waiter in PresenceCloud. Here mesh-based design performs better. ( two ) When the figure of brothers additions, buddy hunt latency is really low in mesh-based design. but suffer to a great extent communicating cost.DecisionFrom the analysis and survey, it’s found that PresenceCloud achieves low hunt latency & A ; shows better public presentation than others. PresenceCloud solve brother list hunt job. Overall, PresenceCloud support a scalable nomadic presence service in big graduated table societal web services.Mentions[ 1 ] Facebook, hypertext transfer protocol: //www.facebook.com.
