Types of Network Security Protections
Network security protection includes a variety of tools, configurations, and policies implemented on your network to prevent any intrusion into your security. The fundamentals of network security include detection, protection, and response. Resources are set up to help you analyze traffic on your network and detect any potential threats before they infect your system. Configurations are set in place to protect your network from intruders and provide you with the tools to properly respond to and resolve any problems that are identified.
Firewalls filter the traffic on your network. They work to prevent and block unauthorized internet traffic and manage authorized access within your network.
Network segmentation divides a network into multiple sections, and each section then acts as their own individual networks. The administrator is able to control the access to each smaller network while improving performance, localizing issues, and boosting security.
Access control gives you the ability to grant or deny access to individual users based on their responsibilities within your network. This will define a person or group's access to a specific application and system on the network and prevent any unauthorized use.
Remote Access VPN
A remote access virtual private network (VPN) provides integrity and privacy of information by utilizing endpoint compliance scanning, multi-factor authentication (MFA), and transmitted data encryption. The remote access VPN is typically provided for telecommuters, extranet consumers, or mobile users.
Zero-Trust Network Access (ZTNA)
The Zero Trust Network grants specific access to an individual user based on the exact role they play within the network. Each individual is only granted access to certain processes or applications they need to complete their job successfully.
Email security is set up to prevent users from unknowingly providing sensitive information or allowing access to the network via a malware-infected email. This security feature will warn or block emails containing potentially dangerous threats.
Data Loss Prevention (DLP)
DLP is a network security technology that aids in preventing sensitive information from accidentally being leaked outside of the network by users. It works to prevent the misuse or compromise of data to protect the network from exposure to outside entities.
Benefits of Network Security
Network security is essential for safeguarding client data and information. It maintains the security of shared data, guarantees dependable network performance, and protects against online threats. An effective network security solution keeps overhead costs at a minimum and safeguards businesses from losses brought on by a data breach or other security incident.
Ensuring legitimate access to systems, applications, and data through network security makes business operations smooth and that services and goods are provided to clients in a timely manner.
Network Security Protection Trends
There are several network security developments that have been moving the industry forward. The most current advancements in network security management include:
- Zero-trust security: This is a security model that encourages businesses to take a "never trust, always verify" approach to security, meaning they should not trust any user, entity, device, or application on the network.
- A focus on education: Training staff on cybersecurity best practices, including how to spot vulnerability in network security, is one of the best ways to prevent data breaches.
- Focusing on incident detection and response (IDR): IDR is a proactive security strategy in which businesses are always on the alert for irregular behavior. It is critical to have an incident mitigation plan in place, so that once an event is discovered, you can execute the proper response promptly and efficiently.
Top 5 Network Security Tools & Techniques
The top five network security tools include:
- Wireshark: Wireshark provides an overview of your live network. It is also a very popular packet sniffer, meaning it examines the contents of data packets to identify threats.
- Metasploit: This Rapid7 network security program allows users to scan over 1,500 processes. It also helps businesses perform various safety evaluations and enhance overall network security.
- Nessus: Nessus locates and fixes vulnerabilities found in computers, operating systems, and applications, including those that are missing or lacking patches.
- Aircrack: Aircrack, a set of tools for breaking WEP and WPA encryption, offers powerful, internet-based solutions for mobile device security.
- Snort: Snort is an open-source IDS that works with all hardware and operating systems. It examines protocols, searches data, and identifies attacks.
Network Security Policy
A network security policy outlines an organization's network security environment. It also specifies how the security policies are applied throughout the network. In addition, a network security policy establishes rules for network access.
How a Network Security Policy Management Improves Business Security
The network's integrity and safety are governed by security policies. They include guidelines for connecting to the internet, using the network, adding or changing devices or services, and more. These rules only work when they are put into practice. By ensuring that policies are streamlined, uniform, and enforced, network security policy management helps enterprises maintain compliance and security.
