Disgruntled employees Spyware Accidents Theft Human Error Copying data onto storage devices. Trojans Roles and Responsibilities: Data Controller ACME LEARNING Ltd must appoint a Data Controller who is there to deal with the data which is about their customers on a computer and also in a filing cabinet. The Data Controller must: 1: Obtain and process the information fairly. 2: Keep it only for what is it was needed for. 3: Use it for and it should only be given out for a specified purpose. 4: It must be kept safe and secured. 5: The information must be kept up to date and correct. 6: Make sure the data is adequate, relevant and not excessive. 7: It must not be kept for any longer than it is needed for. 8: Give a copy of his/her personal data on their request. Every Employee that works for ACME LEARNING LTD has to be given training on how to use and handle the data. Rules for:1. Data storage: Data on hard drives cannot be deleted. The data has to be stored on the network drive where the I.T department can back it up when they need to. Data that is on paper has to be kept in a safe place. Data has to be protected by strong passwords. All data has to be stored on the server and data has to in a safe location. The Data Controller and only the people who need to access the data are allowed to look at it. Servers and computers that have data have to be protected by a firewall and security software. Data on CDs or DVDs has to be locked away. The servers have to have different sites in case one site goes offline. Data should not be saved on laptops or other mobile devices. There will be two different databases for both staff and students information. The data cannot be stored locally have it in a place where it can be backed up every night. Data has to be backed up every night. The usb ports on all the machines have to be disabled. Every computer in the building has to be rebooted every night at a certain time. There are two databases one for staff and the other for students information. Users have to logout of their computer to make the data stays safe. The person that looks at the data should be able to see the quantity of the data and the duplication. 2. Data use When looking at data on a computer all employees must have their computer locked when they are away from their desk. Employees cannot make a duplicate of any data on a file. When data is being transferred electronically it has to be encrypted. 3. Data accuracy: ACME Learning LTD must keep the data up to date and accurate. Data that is inaccurate should be updated to the correct data by someone that is allowed to edit the data. There are staff that are allowed to edit the data and other staff who are only allowed to read the data. 4.

This method will pollute the air.   The data on the tapes can be degaussed. The company can get someone to come in and do it to witness that the tape has been degaussed properly.

Virus, Worms and Hackers :: Computers Technology Essays

Virus, Worms and Hackers Computer viruses were first widely seen in the late 1980s. They were caused due to several reasons. The first factor was rapid growth of personal computers. Before this decade personal computers were not seen in many houses. They only computers used were expert computers which were locked in laboratories around the world. During the 1980’s Computers started to sell to several smaller business’s and homes after the release of the IBM PC in 1982 [1]. After its launch, personal computers slowly started spreading to businesses, homes and universities around the world. The second reason was bulletin boards where users could dial up a bulletin board with a modem and download different programs [2]. The most popular programs were games. Users also downloaded simple word processors and spreadsheets. Bulletin boards led to the precursor of the virus which is know today as the Trojan horse. Trojan horse is a program which can trick the user in to downloading it. This can be done very easily changing the name of the file. When a Trojan program is downloaded on a local computer it can do a lot of harm to it. It can potentially erase all the contents of the hard disk on the computer. Trojan horses hit a small number of people because they are discovered easily. Either the bulletin board would erase the file from the system or the people would send out messages to warn one another. The third reason was growth of floppy disks. Many programs could fit into a single floppy disk. Most computers did have hard disks so computers would just load everything off the floppy when switched on including the operating system. Computer viruses can be very mysterious and grab our attention. Viruses can show us how vulnerable we are to attacks. A well engineered virus can have a very harmful effect on the internet. An example of this is the worms we have seen in the last few years. MyDoom worm which infected a quarter million computers in a single shook the whole internet community. In March 1999 the Mellisa virus was so powerful, it forced many large companies including Microsoft to completely turn off their email systems until the virus could be contained. The ILOVEYOU worm in 2000 had a similar effect. The most astonishing thing is that these worms were very simple in their implementation. Worms usually exploit some sort of security hole in a piece of software or operating system.

Comparative Paper on the Princess Bride and Copper Sun Essay

Even though the two heros in Princess Bride and Copper Sun have many similarities, they also have an abundance of differences. Amari is the protagonist of the book Copper Sun, which talks about her life as an abused slave. Wesley is the lead character of the movie Princess Bride; in the movie, he leaves his beloved Buttercup to make enough money to support them and has to come save her when she is about to marry Humperdinck, the prince and the man she does not love. These two stories may seem completely different but they have more in common than what meets the eye. Both Amari and Wesley survive their quests with determination and they fight for what they believe is important. A good example of when Amari shows determination is when she comes upon a river that lies between her and freedom, â€Å"We come too far to stop now† (Draper 84%). She is so close to her goal she is unwilling to stop now just like when Wesley is on the verge of death and he still forces himself to get up and fight for Buttercup, â€Å"I told you I would always come for you† (The Princess Bride). However, they have multiple differences, one of which is how Amari is not afraid to show emotion and Wesley’s emotion is in absence when he is the Man in Black. Both protagonists are very comfortable and secure in their hometowns, but they are both briskly ripped away from their comfort zone when they are obligated to start their quests. Amari lives in a relatively poor area of Africa and Westley lives on a farm in his medieval universe. These courageous heroes must find their way through a dangerous quest; their journeys have similarities and differences but the importance is what compels them to complete their quest. Amari and Westley’s heart and soul was shaped by this quest. The scars left behind by the quest will not heal and the memories will be burning in the back of their minds forever. Both of these strong willed characters went through impossibly difficult conditions and tests to accomplish their goal. Just in the beginning of the story, Amari has endured a gr eat deal of pain; she has been stripped from her village and family and the white men have treated her horribly, â€Å"This day she wanted to die† (Draper 2%). Another example is when Amari is reminded of her past and all she has left in her is shame this proves that not only has she gone through horrible memories but all that will never be forgotten. Wesley has started this quest with his own choice. Amari was taken abruptly and unlike Wesley. In conclusion they had their own reasons to start their incredible journeys. Risking your life just to find the lost is not something you do without motivation. Both of these exciting heroes have found themselves in the need to find either their lost true love or their perished freedom. Throughout these intriguing stories both Amari and Wesley have fought for what they thought deserved a battle. Wesley has swung his sword and punched his enemies and now he has finally came to the point where he has found Buttercup, â€Å"I told you I would always come for you† (The Princess Bride). Wesley is reassuring buttercup that no matter the risks he will always come, fight for her and that she is his mo tivation to put his life on the line. â€Å"You know, certain people are chosen to survive. I don’t know why, but you are one of those who must remember the past and tell those yet unborn. You must live† (Draper 13%). Motivation is the force that pushes and pushes the characters to continue with strength and this force is prominent in both Amari and Wesley. These quests have a rope slowly burning but finally the rope has come to an end and all that is left are the ashes. In the burning village that Amari used to call home, she had friends and family but once she was left to live and serve at the Derby farm she thought a friendship would never be something she could achieve. After a long time spent at the Derby farm, Amari and Polly have now realized that their lives are stringed together from then on. This came to a shock as Polly and Amari try to hide the fact that Mrs. Derby has had an affair with a slave situated at the farm as well, â€Å"She realized then how deeply her life was entangle with those of the slaves she had once so despised† (Draper 51% ). Polly has been with Amari through one of the worst and unpleasant journeys a character could have gone through, Polly no longer judges Amari by her skin nor does Polly think of slaves as filthy animals. Wesley has always had Buttercup’s love and even after his quest he still has her love, compared to Amari that no longer has Besa or his love. Wesley is trying to explain to Buttercup that their love is unbreakable, â€Å"Do you think this happens every day† (The Princess Bride). Amari had once eternal love but all was stripped away from her with every slash of the whip and every unbearable night spent with disgusting men. Many dangers and obstacles have been in the characters paths but now they survive with all that is left, the effects, results and memories. If the lost had never been misplaced then there would be no found or any quests. A quest starts with a loss of any sort, in this particular case it was freedom and love. Amari was just the matchstick that started the fire from within Polly and that lead to the roads made of gold in Fort Mose. Wesley just had to find Buttercup to keep his fire going. However, they all went through inexplicable danger and horror but all this just started as a quest to find what they thought was needed. Works Cited Draper, Sharon M. Copper Sun. Illus.

rochester castle essays

rochester castle essays Was Rochester Castle an Important Military Site in the Middle Ages Rochester Castle was built in 1088, by the Bishop of Rochester - Gundulf. It was known that the Bishop owed the King - King William Rufus, a sum of 100. To settle the dispute the King ordered Gundulf to build a motte and bailey castle at Rochester. Th cost was 60, and the money came from Gundulf. The structure of the castle consisted simply of a single stone wall. In 1122, a square stone keep was built inside the bailey, by John of Worcester. In 1230 a cross wall was built. It divided the Bailey into two parts - the outer bailey and the inner bailey. This information was extracted from the Textus Roffensis - Register of Rochester castle. During it's existence, Rochester Castle was sieged three times. Once in 1088, then 1215 and finally in 1264. The siege in 1088 was against King William II, as his brother, Robert and his uncle, Odo, wanted to overthrow him and place Robert on the throne. The plan failed and Robert remained king. The siege in 1215 was against King John because he refused the nomination of Simon Langton as Archbishop of Canterbury. Langton became Archbishop, and was appointed to 'look after the castle', but the king asked for it to be returned himself as the agreement to which this adhered to had expired. Langton refused the order and so a siege took place. According to Roger of Wendover, the king undermined the east tower and set fire to it. This shows that the King valued the castle a lot as he was prepared to fight for it. In 1264 another siege occurred. There was a civil war between he king and his subjects, so they capture Rochester Castle. However when they heard that the king was returning to Rochester accompanied by his son, they abandoned the siege and fled. I think that the reason for the abandonment of the siege was that they did not think that they had a chance against the king and his son. From each of these sie...

Programming SQLite in C Tutorial Two

Programming SQLite in C Tutorial Two This tutorial is the second in a series on programming SQLite in C. SQLite stores a collection of tables in a single file database, usually ending in .db. Each table is like a spreadsheet, it consists of a number of columns and each row has values. If it helps, think of each row as being a struct, with the columns in the table corresponding to the  fields in the struct. A table can have as many rows as will fit on a disk. There is an upper limit but its huge 18,446,744,073,709,551,616 to be precise. A table can have up to 2,000 columns or if you recompile the source, you can max it to an awesome 32,767 columns. The SQLite API To use SQLite, we need to make calls to the API. You can find an introduction to this API on the official Introduction to SQLite C/C Interface web page. Its a collection of functions and easy to use. First, we need a handle to the database. This is of type sqlite3 and is returned by a call to sqlite3_open( filename, **ppDB). After that, we execute the SQL. Lets have a slight digression first though and create a usable database and some tables using SQLiteSpy. (See the previous tutorial for links to that and the SQLite Database Browser). Events and Venues The database about.DB will hold three tables to manage events at several venues. These events will be parties, discos, and concerts and will take place at five venues (alpha, beta, charlie, delta, and echo). When you are modeling something like this, it often helps to start with a spreadsheet. For simplicities sake, Ill just store a date not a time. The spreadsheet has three columns: Dates, Venue, Event Type and about ten events like this. Dates run from 21st to 30th of June 2013. Now SQLite has no explicit date type, so its easier and faster to store it as an int and the same way that Excel uses dates (days since Jan 1, 1900) have int values 41446 to 41455. If you put the dates in a spreadsheet then format the date column as a number with 0 decimal places, it looks something like this: Now we could store this data in one table and for such a simple example, it would probably be acceptable. However good database design practice requires some normalization. Unique data items like venue type should be in its own table and the event types (party etc) should also be in one. Finally, as we can have multiple event types at multiple venues, ( a many to many relationship) we need a third table to hold these. The three tables are: venues - holds all five venueseventtypes - holds all three event typesevents - holds the date plus venue id plus event type id. I also added a description field for this event eg Jims Birthday. The first two tables hold the data types so venues have names alpha to echo. Ive added an integer id as well and created an index for that. With the small numbers of venues (5) and event types (3), it could be done without an index, but with larger tables, it will get very slow. So any column that is likely to be searched on, add an index, preferably integer The SQL to create this is: The index on the events table has date, id-event, the event type, and venue. That means we can query the event table for all events on a date, all events at a venue,all parties etc and combinations of those such as all parties at a venue etc. After running the SQL create table queries, the three tables are created. Note Ive put all that sql in the text file create.sql and it includes data for populating some of the three tables. If you put ; on the end of the lines as Ive done in create.sql then you can batch and execute all the commands in one go. Without the ; you have to run each one by itself. In SQLiteSpy, just click F9 to run everything. Ive also included sql to drop all three tables inside multi-line comments using /* .. */ same as in C. Just select the three lines and do ctrl F9 to execute the selected text. These commands insert  the five venues: Again Ive included commented out text to empty tables, with the delete from lines. Theres no undo so be careful with these! Amazingly, with all the data loaded (admittedly not much) the entire database file on disk is only 7KB. Event Data Rather than build up a bunch of ten insert statements, I used Excel to create a .csv file for the event data and then used the SQLite3 command line utility (that comes with SQLite) and the following commands to import it. Note: Any line with a period (.) prefix is a command. Use .help to view all commands. To run SQL just type it in with no period prefix. You have to use double blackslashes \\ in the import path for each folder. Only do the last line after the .import has succeeded. When SQLite3 runs the default separator is a : so it has to be changed to a comma before the import. Back to the Code Now we have a fully populated database, lets write the C code to run this SQL query which returns a list of parties, with description, dates and venues. New to SQL? Read What is SQL? This does a join using the idvenue column between the events and venues table so we get the name of the venue not its int idvenue value. SQLite C API Functions There are many functions but we only need a handful. The order of processing is: Open database with sqlite3_open(), exit if have error opening it.Prepare the SQL with sqlite3_prepare()Loop using slqite3_step() until no more records(In the loop) process each column with sqlite3_column...Finally call sqlite3_close(db) Theres an optional step after calling sqlite3_prepare where any passed in parameters are bound but well save that for a future tutorial. So in the program listed below the pseudo code for the major steps are: The sql returns three values so if sqlite3.step() SQLITE_ROW then the values are copied from the appropriate column types. Ive used int and text. I display the date as a number but feel free to convert it to a date.​ Listing of Example Code

The American Navy in The War Of 1812 Essay Example | Topics and Well Written Essays - 750 words

The American Navy in The War Of 1812 - Essay Example In fact, the war of 1812 broke out because Britain, France, Naples, Spain, and the Netherlands were all engaged in capturing more and more American ships and the number of captured American ships over the thirty year period from the Revolutionary War to 1812 was nearly 1500. That means an average of more than 30 ships in a year. It seems that they were all trying to exploit the vulnerability of the first democratic nation in the world that was young in all stages of development. It was this situation that made America declare war against Britain despite its much smaller Navy as compared to that of Britain. At this juncture, it seems useful to look into the history of the most prominent figures of the 1812 war. One of them was Isaac Hull who was the commander of USS Constitution. Admittedly, USS Constitution was a well-built ship, and it increased the number of guns on board to 50 during the war under the guidance of Hull. As a result of its better hull strength, broadside weight, and better gun power, the USS Constitution under the command of Hull effectively withstood the British attack, and returned heavier firepower, thus resulting in considerable loss to the British Navy. In August 1812, the USS Constitution captured the British Guerriere’s with this superior firepower. Another such prominent figure was Master Commander Oliver Hazzard Perry who was sent to face the British in control of Lake Erie. The British had better guns and bigger and stronger ships as compared to the vessels in the US fleet.

The presidency of Andrew Jackson and the Bank War Research Paper

The presidency of Andrew Jackson and the Bank War - Research Paper Example However, renewal of character could still be possible after the then current charter could expire in the year 1836. Thus to prevent this he rolled out a strategy that was aimed at crippling the bank economically. While acting against the advice of the Congress and cabinet members, President Andrew replaced resistant Secretaries to the Treasury and ordered that federal funds should be deposited into other banks other than the second bank of the United States. Following the president’s directive, the second bank’s president made a countermove in the economy to let people feel the need for the second Bank of America. By so doing, Nicholas Biddle the central bank president created a financial crisis that led to heated debate in the Congress, the press and the public. Businessmen being the most affecting, protested, asking the president and the bank’s management to end the bank war (Rothbard, 510). After people had learned of the dangers of the central bank, there were minimal needs for the renewal of the charter, hence leading to its closer in the year 1836 which was a victory for President Andrew
