1.6 SYSTEM SECURITY

1.6 SYSTEM SECURITY

1. Banking system money transfers

   • Block chain technology
     • Rather than one individual or company having your account/leasures many people do in order to look for changes and or errors

2. A bank would charge a small amount of money from an online purchase as would the use of crypto currency one book keeper would be rewarded for the transaction

3. Desk top Machines are used for book keeping

   • these are used in order to heighten their chances of receiving the random award this is known as mining
     • 20000 desktop pc's
       • £500 average per desktop
         • around 500,000 per mine

4. Added electricity cost of fans to stop pc's from over heating as they are in 24/7 use

   • Mines are stored in colder countries in order to try and reduce energy consumption
     • Geo-Thermal Energy is available in countries such as iceland and is much cheaper taking down energy costs saving money due to relocation
       • Around 100,00 Euros per month spent on energy

5. Mines aim to make £10,000,000 a month

   • This is the targeted minimal depending on the month
     • Receiving the random award is very important to the process as without the "mining" would earn them no money and they need profit due to money spent on electricity and desktops

6. When "Mining"You do not take someone else's money new currency is produced as a result of a transaction

7. Forms of attack

   • The Threats Posed To Networks
     • Malware
     • Phishing
     • People as the weak point in secure systems (social engineering)
     • Brute Force Attacks
     • DDOS
     • Data Interception And Theft
     • SQL Injection
     • Poor Network Policy
   • Identifying and preventing Vulnerabilities
     • Penetration testing
     • Network forensics
     • Network Policies
     • Anti-Malware Software
     • Firewalls
     • User Access Levels
     • Passwords
     • Encryption
   • Key Words
     • Malware
     • Viruses
     • Worms
     • Trojan Horses
     • Phishing
     • Social Engineering
     • Data Interception
     • Network Policies

8. Malware

   • Otherwise Known As Malicious Software
   • Software Which Can Be Malicious If Damaging To A Computer Or Network
   • Examples Include: Viruses, Worms And Trojan Horses
     • Viruses
       • Malicious Software Designed To Cause Harm To A Network Or Computer System
       • Attaches Itself To Programs Or Files On A Computer Or Server
       • Can Affect All Components Of An Operating System
       • Around 82,000 Viruses Are Made Each Day
     • Worms
       • Replicates Itself In Order To Spread To Other Computers
       • Often Using A Computer Network
       • in order to achieve this, the worm exploits vulnerabilities across the computer network
       • Unlike a virus, it does not need to attach to a program
     • Trojan Horses
       • Malicious Computer Program
         • Designed To Access A Computer By Misleading Users Of Its Intent
         • Example: Email Appearing to have been sent from a bank asking to download security software which would improve security where in the fact the software intention is to give the unauthorised access to the system

9. Social Engineering

   • Relies On Human Interaction (Social Skills)
   • Commonly involves tricking users into breaking normal security procedures
   • Method Does Not Revolve Around Technical Cracking Techniques Such As Worms Or Viruses
