As more and more businesses move their operations to the cloud, it’s important to make sure that your network is secure. Azure provides a number of features to help you secure your network, and this article will discuss some of the best practices for using those features.

Azure network security best practices

Azure network security best practices:

1. Use network security groups to control inbound and outbound traffic.
2. Use Azure Firewall for centralised filtering of traffic.
3. Use Azure DDoS Protection to protect against denial of service attacks.
4. Use Azure Private Link to securely access Azure PaaS services.
5. Use Azure Bastion to provide secure RDP and SSH access to VMs.

How to keep your Azure network secure

Azure networking provides many features to help keep your network secure. You can control access to your network using network security groups and Azure Firewall. You can also encrypt data in transit using VPNs and ExpressRoute. Lastly, you can monitor your network activity using Azure Monitor and Azure Log Analytics.

Best practices for securing an Azure virtual network

Best practices for securing an Azure virtual network include:

1. Restricting network access to only trusted users and devices. This can be accomplished by implementing network security groups and access control lists.

2. Configuring Azure Firewall and other security features to monitor and control inbound and outbound traffic.

3. Keeping the virtual network architecture simple and flat to reduce the attack surface.

4. Implementing multi-factor authentication for accessing the Azure portal and other resources.

5. Keeping the Azure environment up to date with the latest security patches and updates.

Azure VPN security best practices

Azure VPN security best practices:

1. Use a strong encryption algorithm: Azure VPN uses the AES256 encryption algorithm by default, which is very strong. However, you can further increase security by using an even stronger algorithm, such as AES512.

2. Use a strong authentication method: Azure VPN supports both password-based and certificate-based authentication. Password-based authentication is less secure than certificate-based authentication, so it is recommended that you use a certificate if possible.

3. Use a strong VPN gateway: Azure VPN gateway uses a 2048-bit SSL/TLS certificate by default, which is very strong. However, you can further increase security by using an even stronger certificate, such as 4096-bit.

4. Use a strong VPN protocol: Azure VPN supports both the IKEv2 and SSTP protocols. IKEv2 is more secure than SSTP, so it is recommended that you use IKEv2 if possible.

5. Use a strong VPN server: Azure VPN server uses a 2048-bit RSA key by default, which is very strong. However, you can further increase security by using an even stronger key, such as 4096-bit.

Azure Network Security Groups

Azure Network Security Groups (NSGs) provide a way to control network traffic to and from Azure resources. NSGs can be used to allow or deny traffic based on various criteria, such as source and destination IP addresses, ports, and protocols. NSGs can be applied to individual subnets or virtual machines (VMs), and can also be applied to an entire virtual network (VNet).

NSGs can help to prevent Denial of Service (DoS) attacks, data breaches, and other types of malicious activity. They can also be used to segment networks and limit the spread of malware. NSGs can be configured to allow only specific types of traffic, and can be updated as needed to adapt to changing security requirements.

When configuring NSGs, it is important to consider the desired security posture and the specific needs of the application or service. NSGs can be configured to allow only specific traffic flows, or they can be configured to block all traffic except for specific flows. In some cases, it may be necessary to allow all traffic and then use NSGs to block specific traffic flows. The decision of how to configure NSGs will depend on the specific security requirements.

Azure DDoS protection

Azure DDoS protection defends against distributed denial-of-service (DDoS) attacks in the cloud. It helps protect your applications from internet traffic that intends to disrupt service. DDoS attacks can come from a single source or multiple sources. Azure DDoS protection is available for both Azure Resource Manager and classic deployments.

DDoS protection is important because it can help keep your applications and services available during an attack. DDoS attacks can cause your applications and services to be unavailable to legitimate users. Azure DDoS protection can help minimize the impact of these attacks.

There are two types of Azure DDoS protection: basic and standard. Basic DDoS protection is included with all Azure services at no additional cost. Standard DDoS protection is a paid service that offers more comprehensive protection.

Azure Application Gateway

Azure Application Gateway is a web traffic manager that provides performance, security, and scalability for web applications. It is a layer 7 load balancer that routes traffic to back-end servers based on HTTP headers, cookies, and other data. Application Gateway can also perform URL path-based routing and SSL offloading.

Azure Load Balancer

Azure Load Balancer is used to distribute traffic across multiple servers. This helps to improve performance and availability of applications. Load balancing can be used to distribute traffic across different regions, or to balance traffic between different types of servers.
