Frequently Asked Questions

What is network security?

Network Security protects your network and data from outside threats. It is comprised of a variety of hardware and software solutions as well as processes or rules and configurations relating to network use, accessibility, and overall threat protection.

Network security involves a variety of tools and technologies for protecting computer networks from cyber attacks. These include access control, virus and antivirus software, application security, network analytics, types of network-related security (endpoint, web, wireless), firewalls and VPN encryption.

What are the benefits of network security?

Network security is a vital component in protecting an organization's data and information, ensuring reliable access to systems and networks as well as protection from cyber threats. A well designed network security solution reduces overhead expenses, safeguards organizations from costly losses that occur from data breaches or other security incidents and ensures legitimate access to systems, applications and data.

What type of network security do I need?

Firewall

Firewalls are used to prevent unauthorized access to your network. They keep out unfriendly traffic and are a necessary part of daily computing. Firewalls are crucial to network security, especially next-generation firewalls that focus on blocking malware and application-layer attacks.

Email Security

Email security refers to any processes, products and services designed to protect your email accounts and any sensitive content from external threats. Most email service providers have built-in email security features, but these may not be enough to stop cybercriminals from accessing your information.

Network Segmentation

Network segmentation is a security strategy that defines boundaries between network segments where assets have a common function, risk or role within an organization. For instance, the perimeter gateway segments a company network from the Internet. Potential threats are prevented from entering the network, ensuring that an organisation’s sensitive data remains inside. Organisations can further define internal boundaries within their network for improved security and access control.

Access Control

Access control restricts access to network applications and systems to authorised users and devices, thereby preventing unauthorised access. Integrations with Identity and Access Management (IAM) products can strongly identify the user, and Role-based Access Control (RBAC) policies ensure that the person is authorised access to the asset.

Intrusion Prevention Systems (IPS)

IPS technologies can prevent, detect and block network security attacks. These attacks include brute force attacks, Denial of Service (DoS) attacks and the exploitation of known vulnerabilities in software systems. An exploit is an attack that leverages a vulnerability in a software system to gain control of that system. When a vulnerability is announced, there is often a window of opportunity for attackers to exploit that vulnerability before the security patch is applied. An Intrusion Prevention System can be used in these cases to quickly block these attacks.

Data Loss Prevention (DLP)

Data loss prevention (DLP) is a cybersecurity methodology that combines technology, policies, and procedures to prevent the exposure of sensitive information outside of an organisation.

Zero Trust Network Access (ZTNA)

The zero trust security model states that a user should only have the access and permissions that they require to fulfill their role. This is a very different approach from that provided by traditional security solutions, like VPNs, that grant a user full access to the target network. A zero-trust network access (ZTNA) solution also known as software-defined perimeter (SDP) is a network security architecture using computer software to implement security measures on an organization's networks. The term "zero trust" refers to the practice of granting limited access for users based on their identity or actions rather than allowing them open access as with other security models.

How are networks managed?

A centralised network management solution is responsible for monitoring the state of the network and taking action to improve security and performance.

A network management platform monitors the state of a network by periodically polling the devices on it for information. After collecting this data, the management station processes it to determine the current state of the network as a whole and the individual devices connected to it. Based on this information, the network management platform can take action to correct issues or otherwise ensure the performance and security of the network.

Network management solutions play a key role in bridging the gaps between network environments and vendors, as well as communicating with all systems on the network. They use vendor-neutral protocols like the simple network management protocol (SNMP) to gather information from an agent installed on the device.
