What isPerimeter Security

Perimeter security refers to the use of traffic monitoring and filtering to protect a network from external threats. It establishes a barrier between an organization’s network and other networks, such as the internet. Traditional methods of perimeter security include firewalls, intrusion detection systems, and virtual private networks.

Securing Your Network Perimeter with Traffic Monitoring and Filtering

Network protection through traffic monitoring and filtering is known as perimeter security. The barrier between a network of an organization and the other networks it borders is referred to as a network perimeter (notably the Internet). Many conventional techniques for protecting a network perimeter include:

What is Perimeter Security?

Perimeter security refers to the security measures taken to safeguard an organization’s network perimeter against unauthorized access and cyber attacks. This security measure is critical for organizations which operate online and have to connect with the internet.

Why is Perimeter Security Important?

The Internet is a vast network that provides a lot of convenience in accessing and sharing information. However, it also opens up networks to potential vulnerabilities and cyber attacks, which can lead to data breaches, network disruption, and other cyber risks. Therefore, securing your network perimeter is essential to protect your data from unauthorized access, cyber attacks, and to keep your network functioning optimally.

What are the Conventional Techniques for Network Perimeter Protection?

There are several conventional techniques for protecting a network perimeter, including:

Firewalls:

Firewalls are the most common perimeter security tools used to filter network traffic. They work by examining incoming and outgoing traffic against a set of predefined rules, allowing or blocking traffic based on the rules.

Virtual Private Network (VPN):

A virtual private network is a security protocol that allows remote access to a network with a secure and encrypted connection. This technique is commonly used to secure remote workers or to provide secured access to a network to authorized personnel.

Intrusion Detection and Prevention Systems:

Intrusion detection and prevention systems (IDP) detect and respond to network attacks by monitoring network traffic, flagging anomalies, and taking action to prevent attacks from penetrating the network.

Antivirus and Anti-Malware Software:

Antivirus and anti-malware software are designed to protect against malware, which can operate unnoticed within the network perimeter.

The bottom line

Securing your network perimeter is crucial for the protection of your organization’s data and network. With traffic monitoring and filtering, you can limit access to your network, detect and prevent unauthorized access, and mitigate the risk of cyber attacks. Using conventional techniques such as firewalls, VPN, IDP, and anti-malware software gives you comprehensive perimeter security.
