Network Security

Network Security

Protect your business with reliable, intelligent, and cost effective network security solutions.

With ever growing threats to organisations through technology, Network Security is essential to every organisation. Network Security not only involves protecting your IT department, but your whole business through deciding network security policies, close IT monitoring and keeping up-to-date with any emerging new attacks as well as implementing a business continuity strategy.

Attacks can be made through various means, including email, employees, corrupt files. Being connected to a network such as the Internet or a VPN comes with risks. It takes only a single computer and/or user to be the weakest link throughout your whole organisations network, which provides criminals with the loophole they require to access your private network, systems and data.

QDos IT provides a wide range of Network Security Solutions to ensure complete security for your IT and business to protect you from:

  • Virus - Malware that inserts malicious code into existing documents or programs, and then spreads itself by various means
  • Trojan horse - A malware attack that disguises itself as something innocent, such as a media file
  • Spam - Unsolicited (Junk) emails or coordinated spam attacks which intentionally consume bandwidth to cause the network to crash
  • Spoof - Use of fake ID to access private data without permission
  • Denial of Service - Large amounts of traffic is sent to hosts to hog bandwidth and deny normal services
  • Replaying - Repeating network traffic which should only happen once
  • Password Cracking - Break into authorised users accounts or use sniffers to capture passwords, or through IP-spoofing, and Trojan horses
  • Break Encryption - Theft of encryption keys and decrypting protected data
  • Phishing - Spam emails designed to steal account information through misleading recipients to insecure websites and requesting private data
  • Packet sniffers - Packet sniffers capture data streams over a network in an attempt to capture private data
  • Maliciously-coded Web sites - These take many forms, from installing Trojan horses to redirecting users to an unrequested site
  • Hardware Loss and Residual Data Fragments - Theft of data from hardware (e.g. computers) through purchasing old IT equipment from businesses that have not cleared the data
  • Zombie Computers - A 'zombie' computer is simply a computer infected with malware that causes it to act as a tool of a spammer by silently sending out thousands of emails from the owner's email address
