Network Security: Definition, Types of Network Security

JSMedia – System network security become very important for computer devices. No wonder because poor security poses a threat to computer devices. Cyber ​​Security Venture predicts that in 2021 at least cyber crime will cost the world’s finances up to $6 trillion.

This prediction is not without reason. Given the current number of cyber crimes is also increasing every year. To keep the business you run safe, you need security on the network. Ensure that the security used is optimal and getting better all the time.

What is a Network Security System?

What is a Network Security System?

Network security refers to systems, security policies and security tools designed to prevent, monitor, and respond to network disturbances that should not occur. It also protects digital assets, including network traffic.

Network security can be in the form of software or hardware specifically designed to respond to various potential cyber attacks targeting the network. There are three different controls on this security system, namely:

1. Physical

Security on physical networks is designed to prevent unauthorized personnel from gaining physical access to certain networks. For example, such as cable cabinets, routers, and so on.

2. Technical

This technical security control is needed so that data stored on the network or data that is in transit can be properly protected.

3. Administrative

This security control consists of policies that regulate user behavior such as user access levels, authentication steps required to how IT staff implement changes to network infrastructure.

Network Security Type

Network Security Type

Irresponsible parties can implement various types of attacks to threaten the development of your business. Therefore, you must have a defense on the network. Here’s the type of security you need:

1. Access Control

You should block unauthorized users and devices from trying to access your network. If an unauthorized user fails to log on to the network, the damage caused can be reduced.

Access control also allows users to increase network protection by restricting user access. For example, you can give the administrator full network access but deny access to certain folders.

2. Antimalware Software

Antimalware and antivirus software can also protect companies from various malicious software. Examples such as ransomware, trojans, worms, to ordinary viruses. Use anti-malware that continuously scans and tracks files on the network automatically.

3. Application Security

Applications that are not officially registered are often used by hackers to access private networks. By using a security system in the application, you can protect any application that has to do with security on the network that is being used.

4. Behavioral Analytics

You just need to know normal network behavior to easily identify anomalies in the network. Network anomaly detection engines allow users to analyze the network, so that when there is a violation users can receive notifications.

5. Data Loss Prevention

Humans are at the forefront of the system network security. Therefore, you must use data loss prevention tools so that sensitive data is not lost, accessed by irresponsible users or misused by certain parties.

6. Email Security

Email security is important because users are often the target of phishing email attacks. By taking advantage of this type of security, it helps you to identify malicious emails and block attacks.

7. Firewall

A firewall acts as a barrier between an untrusted external network and the internal network you are using. Administrators generally configure specified rules to block or allow certain network traffic.

8. Intrusion Prevention Systems

This is a security system which is also called intrusion detection. Its function is to scan and analyze network traffic or packets, so that various types of attacks can be easily identified by the system.

9. Virtual Private Network

A tool used to authenticate communication between networks and devices. A VPN works by creating a secure, encrypted tunnel so that devices can connect to the internet. By using a VPN, you are protected from prying eyes.

10. Web Security

Web security is a security measure needed so that users can ensure safe use of websites when connected to internal networks. Web security helps to prevent attacks on websites that use a browser as a network entry point of access.

Network security become very important for website users so that the security of accessing the network is guaranteed. Use any of the security listed above to optimize the network.
