Network Security

1. Network Prevention Methods

   • Anti-malware software- software program designed to prevent, detect and remove malicious software.This stops malware attacks
   • Firewalls-protects a network or system from unathorized access from attackers. This stops Brute force attacks
   • User access levels- different levels of access given to different people to make sure the network remains secure. This stops social engineering and ransomeware attacks
   • Password Strength Checker-checks the strength of your password and if its easily guessable. This stops brute force attacks
   • Data Encryption-data encryption translates data into a code so that only people with a password or decryption key can read it. This prevents packet dropping and malware attacks
   • Storage Device Virus Scanning-scans your storage device and files for viruses and malware.This stops malware attacks
   • Penetration Testing- also called pen test is the practice of testing a computer system, network or web application to find vulnerabilities that an attacker could exploit. This stops malware attacks
   • Network Forensics-is the recording and analysis of network events in order to discover the source of the attacks. This stops data interception and brute force attacks
   • Network Security Policies- a formal document that outlines the principles to enforce security on a computer network. This stops all attacks that include dowlnoading and adding things to your files

2. Network Vulnerabilities and Risks

   • Malware- software which is designed to disrupt, damage or gain access to a computer system to steal infomation
   • Phishing- phishing is where an attacker sends an email to someone that distributes links or attachments that can perform a variety of functions including the extraction of logins and other infomation
   • Ransomware- software designed to block access to a computer system until a sum of money is paid
   • Trojan horse- a malicious computer program which misleads users of its true intent
   • Brute force attack- is a trail and error method used to obtain information such as pin numbers. software is used to generate a large number of consecutive guesses to try.
   • Denial of Service- a cyber attack where the attacker makes a machine or network resource unavailable
   • Social Engineering-manipulating people to give out there infomation
   • Man in the Middle is where an attacker secretly relays and alters the communication between two parties who believe they are in direct communication
   • Data Interception- the auauthorized interception or taking of infomation.
   • Eavesdropping/packet dropping- unauthorised interception of a private conversation
   • Message Tampering-illegally making changes to something you should not.
   • SQL Injection- a computer attack in which code is embedded in a poorly designed application. the data then produces database query results or actions that should never have been executed.
