We are living in an Internet age now. Organizations nowadays are more carefully progressed than any other time in recent memory. And Business now more concern about their network security of their informations. And with the improvement in technology, organizations have focused more on their security postures and working to enhanced as well.

In this blog post on network security will discuss briefly on below topics, and will give you a good clarity on Network Security.

What Is Network Security?

There are many network hackers who attempt to damage our business network, violate our privacy and make it impossible to the Internet services. Attackers that are always trying to find and exploit vulnerabilities. Network Security is a protocol designed and developed to protect the network. It is designed to protect usability and integrity of your network and data.

It is developed and rely on both hardware and software technologies. And it helps to target a variety of threats

Network Security Types

There are several ways an Organization can adopt to secure their network as well as data. So below are Network security types which helps to keep our network secure. There are several types but here will take few important types.

Firewall

It a barrier between your Inbound and outbound traffic on your network. They use a set of defined policies and rules to allow or block traffic in your network. A firewall can be hardware, software, or both. It monitors incoming and outgoing network traffic and permits or blocks data packets based on a set of security rules.

Anti-virus and anti-malware software

When you install a malicious software, it includes viruses, worms, Trojans, ransomware, and spyware which affects the network as well your local system. Sometimes malware will infect a network but lie dormant for days or even weeks. The  anti-malware softwares not only scan for malware upon entry, but also continuously track files to find viruses and remove them, and fix damage.

Access control

If you want to keep your network safe and to keep out potential attackers, you need to recognize each user and each device available on your network. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC).

DLP

Use Data loss prevention (DLP) policies to help identify and protect your organization’s sensitive information. For example you can set up policies to help make sure information in email and docs isn’t shared with the wrong people. It may be with internal as well as external users. DLP also helps top stop people from uploading, forwarding, or even printing critical information in an unsafe manner.

VPN

VPN networks are normally used within the commercial enterprise international. It both allow employees and  and different authorized employees to set up a connection to the company’s servers. From a remote location or to connect two of the company’s separate, private networks into one wide vicinity network (WAN). Once connected through a VPN, personnel or branch offices get an inner IP address, and have get admission to do something that they could typically access if they have been physically plugged in to the private network. Typically, a remote-access VPN uses IPsec or Secure Sockets Layer to authenticate the communication between device and network.

Wireless security

If you have configure Wireless network in your environment keep in mind, Wireless networks are not much secure than wired network. Without stringent security measures, installing a wireless LAN can be like putting Ethernet ports everywhere. To prevent an exploit from taking hold, you need products specifically designed to protect a wireless network.

Web security

This is a very major part for keeping our network environment secure. A web security solution will control the surfing of web for your employees.Setup of web security helps to block web-based threats, and deny access to malicious websites. It will also protect your web gateway on site or in the cloud. “Web security” also refers to the steps you take to protect your own website.

How do you get benefit from network security being a business and single user ?

In this digital age if you want to run a smooth business and satisfy your customer being a digital service provider you must take care of your network security. Every organization that wants to deliver the services that customers and employees demand must protect its network. Network security also helps you protect proprietary information from attack. It also protects your reputation.

What is Network Security Attack ?

In very simple word when Network security attack happens by a hacker or so it means of unauthorized actions against private, corporate or governmental IT assets and sensitive information in order to destroy them, modify them or steal. A network security attack also means to perform other malicious activity.

There are two main types of network attacks:

  • Passive: Attackers gain access to a network and can monitor or steal sensitive information, but without making any change to the data, leaving it intact. But it does not affect system resources.

  • Active: Attackers not only gain unauthorized access to your network but also modify data, either deleting, encrypting or otherwise harming it.
Network Protection Best Practices

Below are the few best practices being a network administrator you can follow.

Segregate Your Network : This can be done using subnets within the same network, or by creating Virtual Local Area Networks (VLANs). It is a best way and basic part of network security is dividing a network into zones based on your business requirements.

Configure Security Devices Correctly : If you have a big network environment configure a firewall at every point of network zones, not just at the network edge. If you can’t, deploy full-fledged firewalls everywhere, use the built-in firewall functionality of your switches and routers and systems. Deploy anti-DDoS devices or cloud services at the network edge. 

Use NAT : Network Address Translation (NAT) lets you translate internal IP addresses into addresses accessible on public networks. You can use it to connect multiple computers to the Internet using a single IP address. This provides an extra layer of security. Because any inbound or outgoing traffic has to go through a NAT device, and there are fewer IP addresses which makes it difficult for attackers to understand which host they are connecting to.

Monitoring Network Traffic : Make sure you have a very good network monitoring system configured to keep track of incoming, outgoing and internal network traffic. With the ability to automatically detect threats, and understand their context and impact.

Combine data from different security tools to get a clear picture of what is happening on the network, recognising that many attacks span multiple IT systems, user accounts and threat vectors.

Conclusion

Every organization, whether its a small, big or mid , industry or infrastructure, requires a degree of network security solutions. Network security helps to protect it from the network hackers, malwares. So that you will have non headache digital business move on.
