Network Security: Types, Merits, and Demerits

The network architecture of today's time is complex, with a security environment that is continuously changing and adversaries that are always seeking for and exploiting flaws. The contexts in which these defects can appear include devices, data, programs, users, and places.

There are various layers to consider when it comes to network security in a business.

Let us discuss the different types of Network Security and how are they used in securing the Network of an organization.

Network Segmentation

The establishment of network segmentation imposes limitations on resources within the network when those resources share a task, risk, or responsibility within an organization. 

Remote VPN Access

Internet-based VPN access for remote access using a VPN, individual hosting or customers can have remote and in-person access to a corporate network, including telecommuters, users of phone devices, and extranet subscribers. 


Incoming network traffic is controlled by firewalls using predetermined protection rules.Firewalls are an essential component of everyday computing. Firewalls, especially Next-Generation Firewalls,intended to stop ransomware and application-layer threats, are the mainstay of network security.

Access Management

Access control identifies the users, groups, and devices that can communicate with two systems or applications, preventing unauthorized access and potential risks.

In addition to the above, network security are segmented into various types including

Email Security

Zero Trust Network Access (ZTNA)


Intrusion Prevention Systems

Data Loss Prevention

Cloud Network Security

Advantages of Cyber security 

Networks can occasionally be either public or private, like those found inside of businesses. Let's examine a few advantages of network security.

Provides protection from cyberattacks

The bulk of network attacks originate on the internet. In this industry, there are experts, and then there are ransomware attacks. If they are careless, they might interfere with several data networks. 

Levels of Access

The security software is accessible to different users at different levels. The authorization strategy is used after the authentication procedure to decide if the customer is allowed access to particular resources.You may have noticed that, for security purposes, some collaborative papers are password-restricted. Who has access to which resources is understood by the software with clarity.

Safeguard your data

As was already mentioned, network security stops unauthorized access. A network holds a lot of sensitive data, including private client information. Anybody who gains access to the network could endanger this private information. Network security needs to be able to safeguard them as a result.

Updates are centralized

Antivirus software must be updated at all times. An outdated version might not offer sufficient defense against attackers. It is not guaranteed that every network operator will abide by it strictly, though. Even without users' knowledge, a centralized network security solution offers the benefit of timely upgrades.

Unified Management

Network anti-malware is controlled by a single person known as the network administrator, unlike PC encryption software. The latter can thwart hackers before they can do any damage, but the former is susceptible to malware and virus attacks. This is because the program was set up on a computer without an internet connection.

Disadvantages of network security

Users can greatly benefit from network security in protecting the security of their data. While there are benefits and merits, there are also certain disadvantages of network security. Let's examine a couple of the disadvantages of network security

Setup is Expensive

A network security solution installation could be expensive. It can be expensive to buy, install, and maintain software, particularly for smaller networks. Here, we're not talking about a single computer, but instead a network of devices that can hold huge amounts of data.

As a result, it will surely cost more because security is the top priority. At no cost should it be disregarded.

Time Consuming

Many of the software programs installed on some systems are difficult to operate. It prevents unauthorized use of two passwords, which are required each time you modify a text, to ensure double security. Additionally, passwords must be unique and contain alphanumeric, special, and numeric characters. Before choosing a password, the client will need to enter a number of example passwords, which could take some time.

Need for Skilled Personnel

It is not particularly easy to build big networks this way. It requires highly skilled professionals who can handle any potential security issues. Hiring a network administrator is necessary to ensure that the network functions properly. To meet the demand, he needs to receive the proper training.

Unskillful Administration

It is understandable for the administrator to occasionally act carelessly after the largest setup is finished and all necessary tasks have been done. He is accountable for regularly checking the logs to look out for potentially harmful users. However, there are times when he simply relies on the system, and this is when an attack takes place. As a result, it is crucial for the administrator to constantly be on guard.


Data and client information are protected by network security. By reducing wasteful costs and expensive setbacks from data breaches, it secures shared storage, offers security against viruses, and enhances network speed. Because there will be less downtime due to unwanted attackers or viruses, it can ultimately save businesses money.

Everything around us has become smart, like smart infrastructures, smart cities, autonomous vehicles, to name a few. The innovation of smart devices makes it possible to achieve these heights in science and technology. But, data is vulnerable, there is a risk of attack by cybercriminals. To get started, let’s know about IoT devices.

What are IoT devices?

The Internet Of Things(IoT) is a system that interrelates computer devices like sensors, software, and actuators, digital machines, etc. They are linked together with particular objects that work through the internet and transfer data over devices without humans interference.

Famous examples are Amazon Alexa, Apple SIRI, Interconnected baby monitors, video doorbells, and smart thermostats.

How could your IoT devices be vulnerable?

When technologies grow and evolve, risks are also on the high stakes. Ransomware attacks are on the continuous increase; securing data has become the top priority.

When you think your smart home won’t fudge a thing against cybercriminals, you should also know that they are vulnerable. When cybercriminals access our smart voice speakers like Amazon Alexa or Apple Siri, it becomes easy for them to steal your data.

Cybersecurity report 2020 says popular hacking forums expose 770 million email addresses and 21 million unique passwords, 620 million accounts have been compromised from 16 hacked websites.

The attacks are likely to increase every year. To help you secure your data of IoT devices, here are some best tips you can implement.

Tips to secure your IoT devices

1. Change Default Router Name

Your router has the default name of make and model. When we stick with the manufacturer name, attackers can quickly identify our make and model. So give the router name different from your addresses, without giving away personal information.

2. Know your connected network and connected devices

If your devices are connected to the internet, these connections are vulnerable to cyber attacks when your devices don’t have the proper security. Almost every web interface is equipped with multiple devices, so it’s hard to track the device. But, it’s crucial to stay aware of them.

3. Change default usernames and passwords

When we use the default usernames and passwords, it is attackable. Because the cybercriminals possibly know the default passwords come with IoT devices. So use strong passwords to access our IoT devices.

4. Manage strong, Unique passwords for your IoT devices and accounts

Use strong or unique passwords that are easily assumed, such as ‘123456’ or ‘password1234’ to protect your accounts. Give strong and complex passwords formed by combinations of alphabets, numeric, and not easily bypassed symbols.

Also, change passwords for multiple accounts and change them regularly to avoid attacks. We can also set several attempts to wrong passwords to set locking the account to safeguard from the hackers.

5. Do not use Public WI-FI Networks

Are you try to keep an eye on your IoT devices through your mobile devices in different locations. I recommend you not to use the public WI-FI network to access them. Because they are easily accessible through for everyone, you are still in a hurry to access, use VPN that gives them protection against cyber-attacks, giving them privacy and security features, for example, using Express VPN.

6. Establish firewalls to discover the vulnerabilities

There are software and firewalls like intrusion detection system/intrusion prevention system in the market. This will be useful to screen and analyze the wire traffic of a network. You can identify the security weakness by the firewall scanners within the network structure. Use these firewalls to get rid of unwanted security issues and vulnerabilities.

7. Reconfigure your device settings

Every smart device comes with the insecure default settings, and sometimes we are not able to change these default settings configurations. These conditions need to be assessed and need to reconfigure the default settings.

8. Authenticate the IoT applications

Nowadays, every smart app offers authentication to secure the accounts. There are many types of authentication methods like single-factor authentication, two-step authentication, and multi-factor authentication. Use any one of these to send a one time password (OTP) to verify the user who logs in the smart device to keep our accounts from falling into the wrong hands.

9. Update the device software up to date

Every smart device manufacturer releases updates to fix bugs in their software. These security patches help us to improve our protection of the device. Also, update the software on the smartphone, which we are used to monitoring the IoT devices to avoid vulnerabilities.

10. Track the smartphones and keep them safe

When we connect the smart home to the smartphone and control them via smartphone, you need to keep them safe. If you miss the phone almost, every personal information is at risk to the cybercriminals. But sometimes it happens by accident, makes sure that you can clear all the data remotely.

However, securing smart devices is essential in the world of data. There are still cybercriminals bypassing the securities. So make sure to do the safety measures to avoid our accounts falling out into the wrong hands. I hope these steps will help you all to secure your IoT devices.

If you have any, feel free to share them in the comments! I’d love to know them.

How Networks Can Support A Zero Trust Architecture

With more people working from home, companies have started to rely on VPNs to grant secure access to users. However, VPNs aren’t the only way for businesses to guarantee a secure connection for workers.

Network World mentions a protocol known as a zero trust architecture, which only grants users the bare minimum of access to a network. Whatever access a user’s job requires is what the **zero-trust architecture **will allow the user to have.

Zero trust works by verifying every single device’s connection to the network. It uses an identity-management system that only allows specific access to certain parts of the network for particular devices. Authorized users no longer have access to any and all parts of the network. They can only get into the specific locations they need to perform their jobs. Zero-trust is an overarching architecture, but certain elements apply to networks, specifically. This article intends to demystify those elements and show how networks can be used to support zero trust.

The Principle of Least Privilege

Beyond Trust tells us that the principle of least privilege states that access rights for every account, user, or device accessing the network has limited access based on what they need to perform their duties. One way that networking professionals can ensure least-privilege access is via network segmentation. When a device or a user logs into a network, he or she is granted access only to the segment of the system where pertinent data is stored.

Networks can quickly implement this using a simple switching technique. By placing different segments in areas that are unreachable from each other, they limit the incidence of a breach. If a user or device is compromised, their limited access reduces the damage to the overall organization. Any applications or data on the compromised machine is limited to where the user or device has access.

Network segmentation can also be performed physically. Different networks can be located in different locations or separate server points, each with their own dedicated server. Suppose the malicious user is trying to hijack a central server. In that case, this setup ensures that only one of the company’s servers becomes compromised, while the rest of the business’s systems intact and safe.

SecOps Teams Wrestle with Manual Processes, HR Gaps

Only about half of enterprises are satisfied with their ability to detect cybersecurity threats, according to a survey from Forrester Consulting – with respondents painting a picture of major resource and technology gaps hamstringing their efforts to block cyberattacks.

According to the just-released 2020 State of Security Operations survey of 314 enterprise security professionals, enterprise security teams around the world feel that they struggle with the growing pace, volume and sophistication of cyberattacks. A whopping 79 percent of enterprises covered in the survey have experienced a cyber-breach in the past year, and nearly 50 percent have been breached in the past six months.
