Network security is one of the top priorities of the IT units in different companies, and this importance comes from the importance of the network itself, as the presence of a network is necessary for data transfer between different company sections, and between company and other companies. For the previously mentioned importance of the networks, you need to be aware about the best types of network security to protect companies.
What are the best types of network security for companies?
To protect the security of your company’s networks, there are a number of technologies and practices that constitute the types of network security, which in turn provide comprehensive protection for the network, and protect your data and information transmitted via the network. The best types of network security procedures that can protect your company’s networks are as follows:
- Next-Gen Firewalls: It is one of the most important network security procedures that are used in companies, as it is analyzing data flow via the network, blocking suspicious traffic, and detecting threats to the network. Examples of premium corporate firewalls include Fortinet FortiGate, Cisco Firepower, and others.
- Cloud firewalls: It is a special type of firewalls that is designed to protect cloud operating systems. Cloud firewalls are provided by the companies providing cloud services. Examples of these firewalls are AWS Shield and Azure Firewalls.
- Zero Trust Network: It is a network technology based on the principle of not to trust any devices or users to pass through the network without verifying their identity. There are a number of applications that provide zero-trust networks, such as the Microsoft Zero Trust Framework, which is integrated with Azure AD.
- Intrusion prevention and intrusion detection systems: These systems are divided into intrusion detection systems, which is designed to detect attacks in the real time, and send notifications to the users, and intrusion prevention which is designed to prevent different types of cyber attacks. Examples of these systems are the Darktrace program, which uses AI to detect security threats and prevent them.
- Centralized security monitoring systems. These systems are dedicated to monitor various parts of the network, and collect information from various sources to detect attacks from various locations, such as IBM QRadar, which is suitable for large enterprises, and Microsoft Sentinel, which is suitable for cloud systems.
- Endpoint Detection and Response, They are the systems that are dedicated to monitor different types of peripheral devices to prevent different types of attacks. An Example on these systems is Microsoft Defender for Endpoint, which can integrate with Windows operating systems.
- Cloud security applications: They are responsible for cybersecurity security of the cloud operating systems. Examples of these applications are AWS Shield and Microsoft Defender for Cloud، which can integrate with Azure cloud operating system.
- Network segmentation techniques: it is one of the most important techniques in network security. Via These applications the network within a company is divided into sections for the purpose of reducing intrusion, such as virtual local area networks (VLANs), which are used in local networks within companies, Zero Trust Architecture technologies, and other network isolation technologies.
- Virtual Private Network and Encryption techniques: these techniques are different, but they rely on the same principle, the encryption. VPN networks encrypt connections between users, which can help save the security of these connections, especially distant connections. Examples of these include OpenVPN, Tailscale, NordLayer, and others. Encryption is one of the basic techniques of network security, as data that is stored or transmitted is encrypted using technologies such as SSL/TLS, which is used to encrypt communications, or BitLocker, which is used for storage.
- Identity and access management solutions. These solutions allow companies to verify user privileges and ensure that only authorized users have access to the network. Networks use applications such as Microsoft Azure AD, which is designed to control access on Windows systems. Some companies also use multi-factor authentication to protect highly sensitive and sensitive data.
- Backup and disaster recovery: it is one of the most important security systems within companies. It involves periodically backing up data to restore it in the event of data loss in emergencies or ransomware attacks or any other emergency situation. Companies use applications, such as Veeam Backup or Acronis Cyber Protect to periodically back up and maintain their data.
- Email security applications: these applications can help secure your Email, in order to save it from Phishing attacks and malware.
In companies, you need to have a network to perform all your required activities, and to have a network you need to secure it and protect it from any threat. So, knowledge about the best types of network security is mandatory, to get a highly certified network.
