Network Security

Security breaches and network security issues can cost your company exorbitant amounts of money due to data or time loss, for example. Ensuring your network is as highly secure as possible is a necessity.

Keeping your network secure allows your employees to focus on their job duties without interruption. Breaches in security can bring down entire networks, damage software and hardware, as well as cause you to lose critical data. Companies and their clients are becoming more vulnerable as personal data is being readily shared over the internet. Digital data collection allows companies to be more versatile and have a broader customer base, but also opens up the possibility of a security breach.

Security breaches can be caused by external threats such as:

  • phishing attempts: defrauding account holders by posing as a legitimate company
  • hoaxes: purposefully masking the truth 
  • attacks from hackers
  • eavesdropping: interception of data
  • identity theft: use of a individual’s private information
  • spoofing attacks: using the address of a trusted computer to gain access to other computers
  • malware: viruses, Trojan horses, worms, adware, spyware, etc.

“Unintentional threats can happen when employees fail to guard their passwords.”

Internal threats, intentional or unintentional, pose a significant problem to businesses as well. Unintentional threats can happen when employees fail to guard their passwords, use easily guessed passwords, or remain logged into the system when their work station is unattended. Employees can fall prey to scams by responding to phishing emails or accidentally giving out sensitive information to crafty individuals.

Some threats may be intentional. For example, unhappy employees may attempt to destroy data or release sensitive information to a competitor. Terminated employees with a grudge already know the infrastructure of your company and may try to login to systems using their old credentials.

Breaches in security such as loss of client data, for example, can decrease client satisfaction and reduce trust in your company and cause you to lose business. Having multiple layers of security is the best way to combat these issues and ensure you have the most secure network possible.


Strong network security protocols include measures such as:

  • Intrusion Detection Systems (IDS) or Intrusion Protection Systems (IPS): An IDS, or IPS, helps to ward off computer intrusions and detect attacks. They monitor connections and provide alerts in the event of intrusion.
  • Firewall: A firewall provides a border or perimeter defense to block outside traffic. It prevents unauthorized access to your private network and can be implemented in hardware, software, or both.
  • Anti-Malware software and scanners: Anti-malware software detect malicious software such as viruses, worms, and Trojan horse and clean the system in case of attack.
  • Secure Socket Layer (SSL): SSL is a group of protocols used to provide security between a web browser and a web site. It creates a secure channel for the exchange of information and provides authentication of clients by using certificates.
  • Virtual Private Networks (VPN): VPNs provide secure access to users outside the LAN. Remote users can perform necessary functions without compromising network security.

These components combined work together to minimize system maintenance and ensure improved network security. JKS can help determine your network security needs and design and implement a system to help you protect your company from possible threats.
