i liked Yaser 's example as simulating the process of securing like the physical protection defense  approaches ...l always think about this in the same way

تابعوا الحلقة علشان تعرفوا اكتر عن منحة مبادرة "بناة مصر الرقمية" والفرصة اللي بتقدمها للحصول على ماجستير مهني من جامعة عالمية مجانًا بالكامل، وإزاي بيتم إعداد قادة من شبابنا على مستوى عالمي
وكمان لو عندكم أسئلة أو إستفسارات عن المبادرة اكتبوها في التعليقات على البوست عشان نرد عليها

حيكون معانا الدكتورة هدى بركة مستشار وزير الاتصالات وتكنولوجيا المعلومات لتنمية المهارات التكنولوجية

Information Security
 1. Introduction
  ○ Security by obscurity
   § Steganography
    □ Hiding data inside another form of data, like using non-used bits in image to hide a message
     § Cool, but not practical.
     § Disadvantages
      ◊ Algorithm secrecy vs. key secrecy
  ○ Cryptography is everywhere and yet if done right, you can barely see it.
  ○ Goals: 
   § Confidentiality
    □ Secrets stay secret.
   § Integrity
    □ Data is not tampered with.
   § Non-Repudiation
    □ No party can deny sending messages.
   § Authentication
    □ Each party can ensure that the sender is what they expect.
  ○ Cryptography
   § Hashing
   § Encryption
   § Signing
   § Protocols
  ○ Random Number Generators
   § Extremely important, almost all encryption/hashing strength is affected by how random the random number generator is.
   § Don't use simple random number, use a cryptographic random number generator with a sophisticated source of entropy.
   § Pseudorandom number generator
   § Dual_EC_DRBG random generator backdoor
 2. Body
  ○ Hashing (one Way)
   § Properties
    □ Fixed length output no matter what size the input was
    □ Very easy to compute the hash of a given message, however very hard to compute from a hash the corresponding input.
    □ Mathematically infeasible to generate a message that has a given hash
    □ Any modification to a message produces a completely different hash that has no relationship to the original message's hash.
    □ It is mathematically infeasible to find two messages with the same hash. Hash Collision
   § Hashing Functions
    □ Provides data integrity, however lacks authentication
    □ Examples
     ® MD5 
      ◊ Considered Insecure
     ® Secure Hash Family SHA-X, Sha-1, Sha-2 [Sha256, Sha512], Sha-3
      ◊ Sha-1 is considered insecure.
      ◊ Sha-1, Sha-2 designed by NSA
      ◊ Sha-3 is not designed by NSA, Competition winner.
    □ Attacks
     ® Brute force
      ◊ CPU's are getting faster and cheaper every day.
      ◊ GPU's are getting faster and cheaper every day.
      ◊ Special Hash calculating hardware is becoming more available especially with the BitCoin push.
     ® Rainbow table attacks
      ◊ Pre-Calculated tables where you can reverse lookup a hash to a value
      ◊ Try www.crackstation.net
   § Hash Message Authentication Codes (HMAC)
    □ Adds authentication to integrity
    □ Can be used with all previous algorithms, HMACMD5, HMACShA1, HMAC256 … etc.
   § Salted Hash
    □ Adds random salt to mitigate rainbow table
    □ Salts are unique per record, and not a secret.
   § Password Based Key Derivation Function (PBKDF2)
    □ RSA Public Key Cryptographic Standard PKCS #5 Version 2.0
    □ Internet Engineering Task Force RFC 2898 Specification
     ® Adds a lot of iterations to slow it just enough to mitigate brute force (default 50,000 iterations)
     ® Adds random salt to mitigate rainbow table
    □ Disadvantage: It can be easily implemented with hardware which makes it vulnerable to bruteforce even with high number of iterations
   § Bcrypt
    □ Password Hashing function
    □ State of the art password hashing
   § Usages
    □ Integrity Check
Password Storage

- Quick history
  ○ Distance learning
  ○ Open educational resource movement
  ○ MOOC coined in 2008 by Dave Cormier
  ○ Khan Academy, P2PU, and Udemy
  ○ Udemy has tools for pros to create courses and publish (also attracting corporate trainers to create courses for enterprises)
  ○ Udacity growing out of Stanford CS courses by Sebastian Thrun
  ○ Coursera growing out of Stanford's Andrew Ng and Daphne Koller
  ○ MITx launched by MIT in response to commercialization of MOOC, then joined by Harvard and renamed edX
 - Cost
  ○ Content is free
  ○ edX offers certificate for 100$ for most courses
  ○ Coursera have some quizzes and grading exercises only for paying students
  ○ Udacity has nano-degrees with projects reviewed only for paying students
 - Interdisciplinary learning
  ○ Importance
  ○ Examples
 - For credit leaning
  ○ Georgia Tech masters 2013 with Udacity
  ○ edX have MicroMasters which offers for credit courses and earn 25% credit of on campus masters

محمد محسن - أغاني تملى الحى

حوار شيق مع المهندس احمد عصام و رحلته في مجال التكنولوجيا و البرمجيات من البداية في القاهرة مرورا بمراحل مختلفة في اوروبا و الولايات المتحدة الأمريكية و حتى المرحلة الحالية من العمل في شركة Apple

	• What defines ethical? -- * 
	• Failing and realizing why it happened.
	• Respect your own capabilities with consideration of (is it hard enough?)
	• What do you do at work?
	• You as a brand, what message do you want to deliver? "What you do is perceived as who you are"
	• Dare to disrupt your life, When nothing is happening for while it is important to look on what have you done for the next step, what you are doing and the next months is basically the present (it is planned and determined and probably the outcome of it is known)
	• The need to explore other areas to empower the current moment.
	• Are you ready to answer all questions in a meeting? 
	• Do you intentionally mislead people with subtle language/words?
	• Starting a startup and how much I wasn't ready for it, how bad I treated people and how much effort did I have to work on my attitude?
	• Are you really as good/bad as you think you are?
	• Let's discuss "There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self." - Ernest Hemingway
	• Opinions and Facts, the critical need to distinguish both from each others.
	• Where/Who/What you are doesn't define you, Anything is subject to change and none should be defining your future.
	• Assuming (good intention)/(Positive attitude) when listening to people changes how people perceive you as ally or adversary
	• Why good language matters at work.
	• What is the difference between pushing the limits and (breaking the law / respecting others / etc)
	• Your values and what drives you.
	• Let's see why greedy will fall short to help you achieve your targets.
	• The multi modes for writing code, communicating and looking back.
	• What do you do while your work is compiling.
	• The balance of listening to others and going your own way. 
	• Picking up answers from Stack overflow. -- * 
When it works, do you know why it works? -- *
