What is Network Security?

Network security refers to all actions to prevent and protect access, use, and integrity of the network and corporate data.

Digital transformation is already a reality in companies. All companies must protect their data to:

• Guarantee operation continuity, preventing multi-million losses.
• Protect customers’ information.
• Prevent damage to their reputation if their security is compromised.

Network security includes specific protection controls added to a network. However, these controls have evolved (and will continue to do so), as networks do, and the methods come to use by hackers to try to breach security.

Likewise, to guarantee that the best protection controls have been added, we must first understand the environment of threats and vulnerabilities on the network and which controls are available, the solutions, and the correct configurations for your network.

How Does Network Security Work?

 Network security combines multiple layers of defense at the perimeter and on the network, where each layer implements policies and controls. This way, authorized users have access to network resources while malicious users are blocked to prevent, for example, DDoS attacks.

DDoS attacks are still a widely used technique to affect resources and exert pressure on organizations that tend to monetize such attacks. Thus, companies need to have comprehensive network protection strategies.

 Types of Network Security

There are different specialized techniques and types of network security to implement this type of defense in depth:

• Access Control:

It blocks unauthorized users and devices from the network. It only allows access to users and devices identified as authorized.

• Antimalware:

This type of network security focuses on the prevention of infections. It aims to stop viruses, Trojans, and worms.

• Application Security:

If your network tends to access third parties or your own applications, it is essential to protect them to prevent intruders from filtering through them. Protection must be implemented both in hardware and software.

• Data Loss Prevention:

Because humans are the weakest link in security, it is necessary to implement technologies and processes to ensure employees do not send confidential data outside of the network, whether intentionally or not.

• E-mail Security:

Pishing is one of the most common ways to access a network. That is why it is essential to have security tools that allow the blockage of incoming messages and the output of confidential data.

• Firewalls:

They are in charge of building a barrier between your internal, trusted network and external, non-trusted networks, including the Internet. This type of network security uses a set of rules defined to block or allow traffic. Firewalls have significantly evolved; the so-called “new generation” firewalls integrate threat intelligence with other features to offer greater protection to companies.

• Intruder Detection and Prevention:

These network security systems scan network traffic to identify and block attacks.

• Security Information and Event Management (SIEM):

These products gather information from different network tools to provide the data needed to identify and respond to threats.

• VPN:

It is a tool that authenticates communication between a device and a secure network. A VPN for remote access usually uses IPsec, or a layer of secure sockets, to perform this authentication.

• Web Security:

It aims to control the use of the Internet by internal staff. That is why it controls web use by the team, blocking threats and access to malicious websites.

The best way to go about network security is always to be aware that your company is exposed to being hacked or being a victim of DDoS attacks, which may interrupt or knock over our network and connections, affecting our company’s operations.

NGIN Services’ Network Security solution is a new and revolutionary defense against attacks that enhances network security. It offers real-time line-rate detection and mitigation on a vast scale. Likewise, it always takes advantage of package-level supervision, automated machine analysis, and infrastructure-based application of all network elements.
