Nowadays, network security becomes more and more significant. Thus, this post mainly talks about network security. You can know the definition, types, and the software of it from this post. Besides, you can know what it protects. Now, keep on your reading.
Overview of Network Security
What is network security? It is the prevention of any additional and existing activities that protect the network and data. Network security includes both hardware and software technologies and it targets a variety of threats. It stops them from entering or spreading on your network. Besides, it covers various computer networks used in daily work, including public and private computers.
Now, let’s see the types of network security. It can be divided into several types. Details are as follows:
The firewall establishes a barrier between your trusted internal network and an untrusted external network (such as the Internet). The firewall can be hardware, software or both. They allow or block traffic by using a set of defined rules. Maybe you are interested in this post – How to Allow or Block a Program Through Firewall Windows 10.
2. Antivirus and Antimalware Software
Antivirus refers to Antivirus software (AV software), and you can call it as anti-virus software or anti-malware. It is a computer program that prevents, detects, and takes action to remove viruses and malware.
If you are looking for a place to keep your Windows devices safe, you should first run the best antivirus software- Windows Defender. Let’s see more details.
3. Data Loss Prevention
Data loss prevention (DLP) is a technique to make sure that end-users don’t send sensitive or critical information outside the corporate network. It aims to identify, monitor and protect your data.

4. Intrusion Prevention Systems
Intrusion prevention system (IPS) scans network traffic to actively prevent attacks. It not only blocks malicious activities but also tracks the progress of suspicious files and malware throughout the network to prevent outbreaks and reinfection.
The virtual private network (VPN) usually encrypts the connection from the endpoint to the network through the Internet. Typically, remote-access VPN uses IPsec or Secure Socket Layer to verify communication between the device and the network.
6. Wireless Security
Wireless networks are less secure than wired networks. To prevent the exploitation of vulnerabilities, you need products specifically designed to protect wireless networks.
7. Web Security
Web security solutions will control your employees ’web usage, block web-based threats and deny access to malicious websites. Maybe this post – How to Remove the “Internet Security Alert” Pop-up Scam is helpful to you.
What Does Network Security Protect
What does network security protect? You can refer to the content below:
Virus: The virus is a malicious, downloadable file, it can be dormant, and you can copy other computer programs by using your code to copy yourself. Once spread, these files will be infected and may spread from one computer to another, and/or destroy or destroy network data.
Worms: It may slow down the speed of the computer network by occupying bandwidth and slow down the efficiency of data processing by the computer.
Trojan: Trojan viruses can delete files, activate other malware (such as viruses) hidden in the computer network and steal valuable data.
Spyware: It is a computer virus that can collect information about individuals or organizations without its explicit knowledge, and can send the collected information to third parties without your consent.
Adware: It can redirect search requests to advertising sites and collect marketing data about you in the process.
Ransomware: This is a Trojan network software designed to make money on personal or organizational computers that make them unusable by encrypting data, thereby preventing access to user systems.
Virus is undeniably the leading threat to computer security, so I think it is necessary to give a brief introduction to the common types of computer virus.
Network Security Software
Network security software is software designed to enhance network security. Many different types of network security software can help protect data in transit, data at rest, and other elements of network settings.
