Believe it or not, but your business is under constant attack from cybercriminals. Whether you’re a small business or a large enterprise, you need to have a network security model in place to protect your data and keep your systems safe. In this blog post, we’ll take a look at some of the most common network security models and how they can help you protect your business. Stay safe out there!
How Network Security Models Can Help Protect Your Business
The Network Security model is an arrangement of hardware, software, process, and policies used to support a network’s protection. The network security model protects a network from unauthorized access or attacks. This model uses different security measures like firewalls, encryption, access control, etc. It is an important part of the overall Information Security Architecture.
The network analyst or CISO (Chief information security officer) performs the security analysis. The impact analysis will help to understand the possible risks. Also, it affects the confidentiality, integrity, and availability of data due to any potential attack.
Prevention Model
The prevention model includes implementing security controls at different levels like network, host, and application levels. Hence, the preventive controls can be technical controls like firewalls, IDS/IPS, or non-technical controls like policy-based security controls, etc.
Detection Model
The detection model refers to methods used to detect an attack or intrusions in the system before it causes any damage. So, the detection models can be either technical means or non-technical means.
Response Model
It includes the methods used to respond to an attack after detecting it. Also, this model also includes the process of recovering from any incident and resuming normal operations. So, the response model may include several procedures like incident response plan, incident log management, etc.
Prevention, Detection, Response Model
The term “critical infrastructure” has been defined by the U.S. Department of Homeland Security (DHS) as: “systems and assets, whether physical or virtual. So, vital to the United States that the incapacity or destruction of such systems and assets would have a debilitating impact on security.” As well as in the “national economic security, national public health or safety, or any combination thereof.”
Hardware and Software Infrastructure
Critical infrastructure can be defined as hardware and software systems. It controls the essential services which make modern society function. Such systems include communications, power generation/distribution, transportation/logistics, and financial services.
This definition is similar to that used by NATO and the European Union. Some sectors of society like telecommunications, energy and financial services are critical infrastructures in their own right. Others like transportation, healthcare, and education depend on critical infrastructures for their functioning.
Network Security Model Summary
Network cybersecurity is a huge topic. Many different models of network security have been developed and implemented over the past decades. A network security key is your Wi-Fi password — it’s the encryption key that protects your internet.
So, it’s super important to keep your network security key as safe as possible. Remember, the stronger the encryption key, the better your network security will be. The third generation of the perimeter security model is also called Network Security Model (NSM).
Moreover, this means that today’s networks face a greater threat than ever before. This means they need more effective defenses than ever before. That’s why we need to be aware of all three network models.
Thus, we can build an effective network security architecture for our organization. It’s recommended to combine all three models to make your network secure.
