Network Security

Network Security

1. Network Prevention Methods

   • Anti-Malware Software
     • protects against infections caused by many types of malware, including all types of viruses, as well as rootkits, ransomware and spyware.
   • Firewalls
     • protect (a network or system) from unauthorised access with a firewall.
   • User Access Levels
     • Network managers can set up groups of users with different levels of access to the network.
   • Password Strength Checker
     • Substitution is very typical by people who think they're making passwords stronger – hackers know this though so it's one of the first things hacking software uses to crack a password
   • Data encryption
     • It makes sure that if someone hacks onto your account they can't see your stuff

2. Network vulnerabilities and risks

   • Malware
     • Designed to disrupt, damage, or gain authorised access to a computer system
       • And it's a computer virus that is designed to reproduce its self and spreads from one file or program to another
   • Phishing
     • It's some sort of engineering that is designed to steal sensitive information from computers
       • Cyber criminals can do this by installing malicious software
   • Ransomware
     • designed to block access to a computer system until some money is paid.
       • But still files could be deleted so it's blackmail
   • Trojan horse
     • Used to break the security system
       • Users are typically tricked by some form of social engineering into loading and executing Trojans on their systems.
   • Brute Force Attack
     • Used to decode encrypted data.
       • Crackers are sometimes used in an organisation to test network security, although their more common use is for malicious attacks
   • Denial of Service
     • It's an interruption in an authorised user's access to a computer network, typically one caused with malicious intent.
   • Social Engineering
