Network Security is a simple process of protecting the networks against the known intent of the cyber criminals to harm; they can do this in a variety of ways, such as deactivating the primary security of the networking firewalls or through forced intrusion. Either way, when the system is compromised, the hackers can retrieve particular parts of the critical user and enterprise data that they like and continue to create havoc as they please. 

Network security is all about preventing this from happening; it focuses on ensuring endpoint security that mainly focuses on individual devices and how these connect with each other to perform dedicated tasks. Network security is a comprehensive way that is all about protecting the networks from unauthorized access and also preventing it from misuse, malfunction, destruction, modification, or improper disclosure of the software systems to unauthorized personnel.

Basics of Network Security

There are basically the 3 basics for the network security, and all the professionals indulged within the labyrinth of network security should fully understand the know-how and detailed working of these basics.


You should configure your work systems as correctly as possible to make sure that all the effects are appropriately maintained, and your system, in turn, is safe from the terrors of illegal hacking or gaining access from unauthorized sources.


You must be able to understand or speculate any changes within your core networking systems. This way, you will know when a recent change has been made within the core of the networking system or if some unauthorized personnel has tried to gain access without authorization.     


After that, you have speculated some problems within the core of your networking systems; you must respond to them as soon as possible. You can begin with understanding the core of the problem and trying to manifest dedicated solutions to eradicate the issue once and for all.

Think of your network as not a single point or a single aspect of technological walls and systems but a territory. This way, even if a hacker has gained access to the secured systems or some part of your networking systems, you can regroup and expel these illicit cybercriminals out of your networking array. These are the various basics of network security.

Network Security Methods

After you have speculated a change within your network, and you want to implement the customized changes within your networking array, some specialized tools and techniques are using which you can comprehend the changes efficiently. This corresponds to the various networking security methods used all over the globe within IT-based industries to emulate changes accurately;

Access Control

You must be able to filter or screen your networking systems for the incoming and outgoing traffic at all times. Even if some unauthorized personnel make their way within your networking array, you must be able to terminate their access right away. Also, you must regulate the users with a minimum number of resources for which they are permitted to work with.


Viruses, malware, or other spyware systems are the coded scripts used by hackers to cripple the working mechanisms of the server systems and penetrate deep within the networking systems by weakening the firewall systems in the first place. Your anti-malware systems must be strong enough to sniff out all such malware lurking freely within your networking array and block the spread or infiltration of these systems any further.

Data Loss prevention

One of the most sensitive and essential network security method is data loss prevention. Data can be lost very easily if its storage is not regulated via dedicated protocols or standards. Staff members can become the most substantial link of unintentionally deleting or sending the data elsewhere, such as outside of the network barriers where it can be used by cyber attackers as they well please.

Email Security

Network security can't be promised until unless the email system is not fully secured from the outside threats and intrusions from the unauthorized sources. Phishing is one of the most common ways, which still, to this date, is being entertained dearly by the cyber attackers to introduce virus/malware to the networking systems and gain access to the secured user/company data. Email security parameters can help to block such emails from the beginning and restrict the infected sources completely to safeguard the on-board data within the network.


Firewalls act as the primary line of defense that works over the instructions provided by the network administrators. Firewalls act as the speculation units for each and every packet of data that reaches your network. These data packets are then filtered and or speculated by the help of firewalls and are not allowed to pass if anything found out of the ordinary. Firewalls act as the border, which restricts the entry of unauthorized data/users within your secured networking system.

Intrusion Detection and Prevention

These are the most advanced technological systems as they work by identifying the data packets reaching the network and correlating their network activity signatures with the database of the known attack vendors or techniques.

Network Security Jobs and Salaries

If you have decided to pursue the career of the network security, then you are in luck because there is an abundance of employment opportunities present for such professionals to work on, such as network security analyst, network security engineer, ethical hackers and the penetration testing experts. The security analysts earn the best which is around $90 to $150K a year. Next, come the security engineers, which without any doubt, make an average of $80-82K a year.

There are a variety of network training courses present online for you to search from and then start learning about the fundamentals of the network security and what re the various best practices that are widely in demand these days. Earn your CEH certification online by applying for learning about the course material and how you can best prepare the exam. After earning the certification, simply unlock your way towards a bright and better future within the networking security and its related systems.
