Network Security Threats

Network Security Threats

1. Malicous Software

   • Trojan Horse
     • They enter appearing as a harmless file to bypass the firewall and once they are in the hacker can any data they want from the computer system or use it as ransom if they want their computer back
   • Worm
     • It enters your computer through emails or USB's and sends a malicious email containing another worm
   • Keyloggers
     • They track your keyboard actions in a search of details such as: bank card details,personal details and phone numbers
   • Viruses
     • Normally enters through a download and is linked to a file or through either a USB,CD or DVD.They also enter through opening emails containing a virus or links.

2. Passwords

   • When a password is bypassed it gives access to who ever has bypassed meaning their data could be taken or removed
   • A way to help stop this is to have a alpha numeric mix in a password so it's much harder to get through with a computer program than scans and try's to detect passwords because it has capitals and numbers in the password

3. No anti-virus,anti-malware or firewall

   • Anti-virus stops viruses entering a computer via scanning them before allowing it through if it detects a virus it'll ask the user what to do it either allow it,quarantine it or burn it
   • Anti-malware stops malicious software entering the system it performs this by scanning the files frequently and will ask the user what to do with it allow it,quarantine it or burn it
   • Firewalls are part of the computer that either allows access for files or programs the enter the system under the permission of the user.If the user doesn't allow it it will bounce it and not allow it in

4. Common sense

   • If the user is giving all their details out and their IP address they are putting themselves in a high risk catergory.This is because anyone who knows the access details can login into anything they want and do what they want
   • If the user learns some online rules and safety guidelines they would be safe and no longer a threat to themselves online
