Let's get to know the different types of network security for your organization's benefit!

Network security in offices is an effort made to protect office networks from unauthorized access and other threats. This involves various techniques that can improve network security, such as setting up firewalls, using data encryption, controlling access to the network, and ensuring that all systems on the network are updated with the latest security patches.

Network security is important for an office because it protects sensitive information, files and data stored on the network. Keeping network connections safe from cyber attacks, malware, and other threats helps keep information confidential and prevent unauthorized access to networks. This also helps guarantee that data stored on the network is accessible only by authorized persons and that the information is safe from unauthorized accessers.

There are many forms of network security that are designed according to their function and purpose. In general, certain types of network security are popular and frequently used, but there are also systems that we are not familiar with. The following are examples of network security that are common for organizations:

1. Email Protection

Email needs to be protected from cyber attacks, theft of personal data or important information. This is why email security is designed to prevent attacks. Email protection usually comes with useful anti-spam software to protect users.

2. Protection on the Web

This type of security is useful for protecting activities on websites, especially online stores that are full of customer data. Internet security usually takes the form of installing a Secure Socket Layer certificate to enhance website security. Websites with an SSL certificate installed are marked with a padlock in the browser's address bar.

3. Wireless Protection

Wireless networks (wireless network) are more vulnerable to attack, because the configuration system and the type of encryption are quite low. Wireless security is useful for preventing this attack so that it can be accessed more securely. An example is Wi-Fi Protected Access (WPA).

4. Endpoint Protection

The device you use can be a target for hackers to steal data. Endpoint Security is useful for protecting personal devices such as printers and fax machines that are connected to the corporate network.

5. Application Security

Not only websites, applications can also become hotspots for customer data theft. To prevent this, organizations must install application security to ensure that their applications are protected from attack.

6. Firewalls

This network security system acts as a protector of internal computer networks against suspicious external networks. Firewalls check network traffic against several protocols and then block potentially harmful traffic.

7. Content Filtering

Content filtering is a Firewall component that is useful for filtering inappropriate websites or emails. Examples include violent, pornographic, self-destructive (suicidal) content, or hate speech.

8. Data Loss Prevention

Data Loss Prevention, or DLP for short, is a tool to protect sensitive data from incidents of loss or theft by unauthorized persons. DLP is designed to work automatically in monitoring and controlling information in computer networks.

9. Behavior Analysis

As the name suggests, this network security system is designed to detect strange and abnormal activity or behavior on computer networks. One of the tools, namely ADE (Anomaly Detection Engines) is useful for analyzing the network and then informing network users when a violation occurs.

10. Virus and Malware Protection

Antivirus is useful for identifying and removing embedded viruses or viruses sent by intruders. Anti-malware, on the other hand, is software that detects malware. Did you know that malware is more dangerous because this attack can take down a network for up to several weeks?

11. Access Control

This type of network security is designed to prevent unknown devices from accessing your network. This can limit the possibility of tampering with your network. In addition, access control is useful for limiting and controlling network user access to certain files or folders.

12. Security Information and Event Management (SIEM)

SIEM works by providing information about activities or records that occur in computer networks and the company's IT environment. Thanks to this SIEM, you can detect the threat and take the necessary action.

13. Network Segmentation

Network segmentation increases network security by dividing the network into several parts. It is designed to enable computers to manage different types of network traffic and exposure to network threats.

14. Virtual Private Network (VPN)

These tools are useful as authentication tools for communication between computers and network devices. How it works VPN creates a path in the form of an encrypted and secure "tunnel" to connect our devices to protect them from threats or network interference.

15. Intruder Alarm System

Another term is Intrusion Detection and Prevention System (IDPS). This system monitors all online activities and then analyzes malicious and suspicious activities. Subsequently, IDPS took steps to suppress the attack.
