The Challenges of Computer Security

             Computer and Network security is both very complex and interesting. Let’s list some sort of challenges;
       I.            Computer and Network security is not simple as it seems; Most of the computer related words can be explained easily, likewise we discussed above Integrity, Availability and Confidentiality. Those words can be explained easily, understand easily. But when it comes to working, those things are quite complex.

    II.             When developing such security system, Developer should always be aware of potential threats. Most of the times successful attacks were designed and attacked by looking complete different way of the problem, So the attacker could identify weak and vulnerable points of security algorithm.

 III.            If we lock up security too hard, then also there will be consequences, such as accessing problems, so it will be a violation of Availability, and also in fact, Integrity. So the security developer has to watch both ends, without loosing either.  The security mechanism should be complex to face various attacks, but not to override CIA triad.

 IV.            Decide, design and place. We should exactly know where to place our security program, otherwise both physically and logically our security mechanism will be vulnerable to third parties, and attackers.

    V.            The most advanced security systems involve more than one person or one company, and also involves more than single particular algorithm or protocol. It is a challenge to connect those parties in a secure way. In purpose of that, Security developers use an encryption key to authorize the access. For example, if the proper functioning of the security mechanism requires setting time limits on the transit time of a message from sender to receiver, then any protocol or network that introduces variable, unpredictable delays that useless.

 VI.            Computer and Network security is commonly known as an endless struggle between security developer and the attacker. But the thing is, if the attacker find a single hole in security chain, attacker can jeopardize the entire security algorithm and, security developer has to reconstruct all the things again.

VII.            There are some modern trends of challenges of Computer security;

§  Defense against botnets
§  Application software security
§  Web services security
§  Electronic payment
§  Electronic passports

Unity Scene - Hierarchy Window A key area of the Unity interface is the Hierarchy Window, which is tied to the Scene View. When you click on a GameObject in the Hierarchy Window, it becomes active in the Scene View.  The Hierarchy Window lists all the objects in your game (like characters, music, effects, etc.) in alphabetical order. But you can also group certain objects together by creating a hierarchical order and assigning Parent and Child categories. What is Hierarchy Window? The  Hierarchy  window contains a list of every GameObject (referred to in this guide as an “object”) in the current Scene. Some of these are direct instances of Asset files (like 3D models), and others are instances of Prefabs, which are custom objects that make up most of your game. As objects are added and removed in the Scene, they will appear and disappear from the Hierarchy as well. By default, objects are listed in the Hierarchy window in the order they are made. You can re-order the o

Kotlin -  Taking advantage out of Kotlin At I/O 2017, Google  announced official support for Kotlin  for developing Android apps.  Kotlin  is a language developed by  Jetbrains , with a quickly growing developer base because of its concise, elegant syntax, and 100% interoperability with Java. I, who am developing android apps for a time was using java for Android Studio IDE language. After android studio 3.0 release, Jetbrains brought Kotlin support. Let's get stared with Kotlin. What You're gonna need, Android Studio 3.0 An Android device or emulator to run the app on The sample code (If you want, I got one below ) Basic knowledge of developing Android apps in the Java language What You're take out of this, How to use the Android Studio's Java to Kotlin converter. How to write code using Kotlin syntax. How to use Kotlin  lambda expressions  and  extension functions  to reduce boilerplate code and avoid common errors. How to use bui

Examples for Integrity, Availability and Confidentiality    Integrity -    As examples for integrity, We can take ATM machines and our VISA cards. There should be integrity in ATM related transactions, so that we could use banking system more trustworthy. As for a example, Say that We use our VISA card for check our account balance, we check from one  ATM and it shows some amount. After we use another ATM to check balance, if it show another amount, There is a lost of integrity.  High integrity            - ATM machines, On-line Banking services Moderate integrity    -     2. Availability -    Availability is accessing data, right time and right people. let's take a system that controls national security the authorized people should always have access, therefore there is no Availability. If an an attacker attacks and blocks availability, Then there is a national security issue.  That count as High availability . If we consider a university website that have access to
