Network security is a collection of technologies and processes used to protect computer networks and their data. It can be used to protect systems against internal and external threats and can be implemented in various ways depending on the needs and resources available.

Why Network Security is important?
Network security is an essential part of assuring the safety and security of computer networks. It protects systems against internal and external threats and can be enforced in various ways depending on the requirements and resources available. It can range from the most introductory measures, similar as installing antivirus software and keeping networks clean of malware, to the most complex strategies, such as designing, building, and managing secure network infrastructures and securing sensitive data through data encryption. Eventually, it’s the network security analyst’s job to understand the risks and vulnerabilities associated with a network, design and implement a result to alleviate those risks and monitor the solution to ensure it’s operating as intended.
How does it work?
Securing a network is the set of actions that organizations use to ensure that information stored on their network is kept private and inaccessible to unwanted people. This process aims to protect data so that it is not accessible to other people or systems unless authorized. The process begins with the prevention of unlawful intrusion and the prevention of unauthorized disclosure of data. It also involves maintaining information and establishing and maintaining passwords, access rights, and file permissions.
Types of Network Security Protections
Firewalls are security devices that stop or mitigate unauthorized access to private networks connected to the Internet, especially intranets. Firewalls sit at the front line of a network and act as a communications liaison between internal and external devices, allowing only traffic defined by firewall policies to pass through them.
Network Access Control
To protect your network from attack, comprehensive access control policies are demanded by both users and devices. Network access control can be set at the most granular level by restricting administrators’ access to specific confidential folders or preventing their personal devices from joining the network.
Cloud Network Security
Cloud network security refers to the methods used to protect a cloud, or network of clouds, against attacks that could expose or use sensitive data in them. Cloud network security helps protect the confidentiality, integrity, and availability of data and communications across the borderless internet.
Intrusion Detection Systems
Intrusion detection is an important component of most organizations’ security infrastructure. This primer explains intrusion detection and the role it plays in defending against network attacks. It details how to select, configure and manage intrusion detection systems for a specific organization’s environment.
SSL (Secure Sockets Layer) encryption and its more modern replacement, TLS (Transport Layer Security), protect data sent over the internet or a computer network. This prevents attackers from accessing sensitive data exchanged between two nodes—typically a user’s web browser and a web/app server. Most website owners and operators have an obligation to implement SSL/TLS to protect their websites and users from unwanted intruders.
Career In Network Security
The network security job market is good. According to the Bureau of Labor Statistics, jobs in Network Security Analysts will grow by 28% from 2016 to 2026. The BLS also states that there are almost 400,000 positions available throughout the United States. If you want to invest your time in education or advancement in a field that is growing rapidly and offers employment opportunities for those who will succeed, network security is definitely a career path worth taking.
