The Quick Wins of DevSecOps

Hello and welcome to my DevSecOps post. Here in Germany, it’s winter right now, and the forests are quiet. The snow slows down everything, and it’s a beautiful time to move undisturbed through the woods.

Here you can pursue your thoughts, and I had to think about a subject that customers or participants at conferences ask me repeatedly.

The question is almost always:

What are the quick wins or low hanging fruits if you want to deal more with the topic of security in software development?

And I want to answer this question right now!

Let’s start with the definition of a phrase that is often used in the business world:

Make or Buy

Even as a software developer, you will often hear this phrase during meetings with the company’s management and sales part.

The phrase is called; “Make or Buy.” Typically, we have to decide if we want to do something ourselves or spend money to buy the requested functionality. It could be less or more functionality or different so that we have to adjust ourselves to use it in our context.

But as a software developer, we have to deal with the same question every day. I am talking about dependencies. Should we write the source code by ourselves or just adding the next dependencies? Who will be responsible for removing bugs, and what is the total cost of this decision? But first, let’s take a look at the make-or-buy association inside the full tech-stack.

What is Python?

Python is an interpreted, object-oriented, high-level programming language with dynamic semantics. Its high-level built in data structures, combined with dynamic typing and dynamic binding, make it very attractive for Rapid Application Development, as well as for use as a scripting or glue language to connect existing components together. Python's simple, easy to learn syntax emphasizes readability and therefore reduces the cost of program maintenance. Python supports modules and packages, which encourages program modularity and code reuse. The Python interpreter and the extensive standard library are available in source or binary form without charge for all major platforms, and can be freely distributed.

what is Natural Language Processing in python?

Natural language processing (NLP) is a field that focuses on making natural human language usable by computer programs. NLTK, or Natural Language Toolkit, is a Python package that you can use for NLP. A lot of the data that you could be analyzing is unstructured data and contains human-readable text.


Libraries for Working with Human Languages in Popular  Python

  1. gensim

Gensim is a Python library for topic modelling, document indexing and similarity retrieval with large corpora. Target audience is the natural language processing (NLP) and information retrieval (IR) community.

Installation

This software depends on NumPy and Scipy, two Python packages for scientific computing. You must have them installed prior to installing gensim.

It is also recommended you install a fast BLAS library before installing NumPy. This is optional, but using an optimized BLAS such as MKL, ATLAS or OpenBLAS is known to improve performance by as much as an order of magnitude. On OSX, NumPy picks up its vecLib BLAS automatically, so you don’t need to do anything special.

Install the latest version of gensim:

    pip install --upgrade gensim

Or, if you have instead downloaded and unzipped the source tar.gz package:

    python setup.py install

For alternative modes of installation, see the documentation.

Gensim is being continuously tested under all supported Python versions. Support for Python 2.7 was dropped in gensim 4.0.0 – install gensim 3.8.3 if you must use Python 2.7.

2.  Langid.py

langid.py is a standalone Language Identification (LangID) tool.

The design principles are as follows:

  1. Fast
  2. Pre-trained over a large number of languages (currently 97)
  3. Not sensitive to domain-specific features (e.g. HTML/XML markup)
  4. Single .py file with minimal dependencies
  5. Deployable as a web service

All that is required to run langid.py is >= Python 2.7 and numpy. The main script langid/langid.py is cross-compatible with both Python2 and Python3, but the accompanying training tools are still Python2-only.

langid.py is WSGI-compliant. langid.py will use fapws3 as a web server if available, and default to wsgiref.simple_server otherwise.

langid.py comes pre-trained on 97 languages (ISO 639-1 codes given):

af, am, an, ar, as, az, be, bg, bn, br, bs, ca, cs, cy, da, de, dz, el, en, eo, es, et, eu, fa, fi, fo, fr, ga, gl, gu, he, hi, hr, ht, hu, hy, id, is, it, ja, jv, ka, kk, km, kn, ko, ku, ky, la, lb, lo, lt, lv, mg, mk, ml, mn, mr, ms, mt, nb, ne, nl, nn, no, oc, or, pa, pl, ps, pt, qu, ro, ru, rw, se, si, sk, sl, sq, sr, sv, sw, ta, te, th, tl, tr, ug, uk, ur, vi, vo, wa, xh, zh, zu

The training data was drawn from 5 different sources:

  • JRC-Acquis
  • ClueWeb 09
  • Wikipedia
  • Reuters RCV2
  • Debian i18n

Example workflow

Example

This example trains a classifier on adjectives mined from Twitter using Python 3. First, tweets that contain hashtag #win or #fail are collected. For example: "$20 tip off a sweet little old lady today #win". The word part-of-speech tags are then parsed, keeping only adjectives. Each tweet is transformed to a vector, a dictionary of adjective → count items, labeled WIN or FAIL. The classifier uses the vectors to learn which other tweets look more like WIN or more like FAIL.

from pattern.web import Twitter
from pattern.en import tag
from pattern.vector import KNN, count

twitter, knn = Twitter(), KNN()

for i in range(1, 3):
    for tweet in twitter.search('#win OR #fail', start=i, count=100):
        s = tweet.text.lower()
        p = '#win' in s and 'WIN' or 'FAIL'
        v = tag(s)
        v = [word for word, pos in v if pos == 'JJ'] # JJ = adjective
        v = count(v) # {'sweet': 1}
        if v:
            knn.train(v, type=p)

print(knn.classify('sweet potato burger'))

Pattern: A Web Mining Module for Python

Pattern

Pattern is a web mining module for Python. It has tools for:

  • Data Mining: web services (Google, Twitter, Wikipedia), web crawler, HTML DOM parser
  • Natural Language Processing: part-of-speech taggers, n-gram search, sentiment analysis, WordNet
  • Machine Learning: vector space model, clustering, classification (KNN, SVM, Perceptron)
  • Network Analysis: graph centrality and visualization.

It is well documented, thoroughly tested with 350+ unit tests and comes bundled with 50+ examples. The source code is licensed under BSD.

Example workflow

Example

This example trains a classifier on adjectives mined from Twitter using Python 3. First, tweets that contain hashtag #win or #fail are collected. For example: "$20 tip off a sweet little old lady today #win". The word part-of-speech tags are then parsed, keeping only adjectives. Each tweet is transformed to a vector, a dictionary of adjective → count items, labeled WIN or FAIL. The classifier uses the vectors to learn which other tweets look more like WIN or more like FAIL.

from pattern.web import Twitter
from pattern.en import tag
from pattern.vector import KNN, count

twitter, knn = Twitter(), KNN()

for i in range(1, 3):
    for tweet in twitter.search('#win OR #fail', start=i, count=100):
        s = tweet.text.lower()
        p = '#win' in s and 'WIN' or 'FAIL'
        v = tag(s)
        v = [word for word, pos in v if pos == 'JJ'] # JJ = adjective
        v = count(v) # {'sweet': 1}
        if v:
            knn.train(v, type=p)

print(knn.classify('sweet potato burger'))
print(knn.classify('stupid autocorrect'))

Installation

Pattern supports Python 2.7 and Python 3.6. To install Pattern so that it is available in all your scripts, unzip the download and from the command line do:

cd pattern-3.6
python setup.py install

If you have pip, you can automatically download and install from the PyPI repository:

pip install pattern

If none of the above works, you can make Python aware of the module in three ways:

  • Put the pattern folder in the same folder as your script.
  • Put the pattern folder in the standard location for modules so it is available to all scripts:
    • c:\python36\Lib\site-packages\ (Windows),
    • /Library/Python/3.6/site-packages/ (Mac OS X),
    • /usr/lib/python3.6/site-packages/ (Unix).
  • Add the location of the module to sys.path in your script, before importing it:
MODULE = '/users/tom/desktop/pattern'
import sys; if MODULE not in sys.path: sys.path.append(MODULE)
from pattern.en import parsetree

Pattern: A Web Mining Module for Python

Pattern

Pattern is a web mining module for Python. It has tools for:

  • Data Mining: web services (Google, Twitter, Wikipedia), web crawler, HTML DOM parser
  • Natural Language Processing: part-of-speech taggers, n-gram search, sentiment analysis, WordNet
  • Machine Learning: vector space model, clustering, classification (KNN, SVM, Perceptron)
  • Network Analysis: graph centrality and visualization.

It is well documented, thoroughly tested with 350+ unit tests and comes bundled with 50+ examples. The source code is licensed under BSD.

Example workflow

Example

This example trains a classifier on adjectives mined from Twitter using Python 3. First, tweets that contain hashtag #win or #fail are collected. For example: "$20 tip off a sweet little old lady today #win". The word part-of-speech tags are then parsed, keeping only adjectives. Each tweet is transformed to a vector, a dictionary of adjective → count items, labeled WIN or FAIL. The classifier uses the vectors to learn which other tweets look more like WIN or more like FAIL.

from pattern.web import Twitter
from pattern.en import tag
from pattern.vector import KNN, count

twitter, knn = Twitter(), KNN()

for i in range(1, 3):
    for tweet in twitter.search('#win OR #fail', start=i, count=100):
        s = tweet.text.lower()
        p = '#win' in s and 'WIN' or 'FAIL'
        v = tag(s)
        v = [word for word, pos in v if pos == 'JJ'] # JJ = adjective
        v = count(v) # {'sweet': 1}
        if v:
            knn.train(v, type=p)

print(knn.classify('sweet potato burger'))
print(knn.classify('stupid autocorrect'))

Installation

Pattern supports Python 2.7 and Python 3.6. To install Pattern so that it is available in all your scripts, unzip the download and from the command line do:

cd pattern-3.6
python setup.py install

If you have pip, you can automatically download and install from the PyPI repository:

pip install pattern

If none of the above works, you can make Python aware of the module in three ways:

  • Put the pattern folder in the same folder as your script.
  • Put the pattern folder in the standard location for modules so it is available to all scripts:
    • c:\python36\Lib\site-packages\ (Windows),
    • /Library/Python/3.6/site-packages/ (Mac OS X),
    • /usr/lib/python3.6/site-packages/ (Unix).
  • Add the location of the module to sys.path in your script, before importing it:
MODULE = '/users/tom/desktop/pattern'
import sys; if MODULE not in sys.path: sys.path.append(MODULE)
from pattern.en import parsetree
