cayodey:
I've been pondering over this for some time that why is security not captured in System Development Life Circle (SDLC) Phase not until resent despite how vital it is.... I will like to know the reason for this and perhaps if its introduction have shown any significant difference.
Thanks.

I once read an article online about the major reason why security has become so big an issue. The most insightful observation the writer made and talked about was that software development organisations usually consider security as an after thought. something you can always incorporate after getting the software up and running. There is always an oversight on security in the development stages and this over the years has proven to be extremely costly.

Security has to be a critical part and equally important a goal as getting the software running.

After loosing almost countless billion dollars for this mistake, software engineers have come to terms with this important aspect of every phase as it is not a phase in itself, but a part of every stage of the development phases.

This is a sample inventory management system.

Count the number of Duplicates

In any Programing Language, Write a function that will return the count of distinct case-insensitive alphabetic characters and numeric digits that occur more than once in the input string. The input string can be assumed to contain only alphabets (both uppercase and lowercase) and numeric digits.

Example

"abcde" -> 0 # no characters repeats more than once
"aabbcde" -> 2 # 'a' and 'b'
"aabBcde" -> 2 # 'a' occurs twice and 'b' twice (bandB)
"aA11" -> 2 # 'a' and '1'

# PYTHON program

# this function handles the counting of the number of
# occurrence of each letter.
def countOccurrence(word):
WordSet = set([])
myDict = {}

for c in word:
WordSet.add(c)

for letter in WordSet:
myDict.update({letter : word.count(letter)})

return myDict


# Example words.
word1 = 'hippopotamus'
word2 = 'hippopotomonstrosesquipedaliophobia'
word3 = 'pneumonoumtramicroscopicsilicovocanokoniosis'

# create different dictionary type variables that takes the
# dictionary returned from the method call.
dict1 = countOccurrence(word1)
dict2 = countOccurrence(word2)
dict3 = countOccurrence(word3)

print (dict1, '\n' )
print (dict2, '\n' )
print (dict3, '\n' )


# the following allows the user to enter the word they want the
# number of occurrence of each letter computed.

# this will prompt the user to enter a word.
new_word = input ("Enter a word: " )

new_dict = countOccurrence(new_word)
print (new_dict, '\n')
