7 Tips to improve the security of your cloud server


The cloud has completely changed the way companies and organizations store and manage their data. The cloud servers offers a wide range of advantages, such as cost reduction, the scalability and the flexibility.

But in the eagerness to adopt the Cloud Computing, many security criteria are omitted, increasing the associated risks. Therefore, it is crucial to take the appropriate precautions to ensure the security those implemented in the cloud.

In this article, we will discuss several tips to ensure the cloud server security, as in the case of Google Cloud Platform (GCP).


1. Use specific and secure data storage options

GCP offers different options for data storage, What cloud-storage which is a cloud-sql. It is important to choose the option that best suits the needs of the organization and that has sufficient capacity to store the data.

In addition, it is essential to have a specific and secure software to protect stored data. For example, it is recommended to use Cloud Storage to store large files and Cloud SQL for applications that require a relational database. In this way, if an affectation were to occur in the server, the information in the repositories and/or in external instances of databases would not be compromised.


2. Protect data with up-to-date antivirus software

To guarantee the cloud server security, it is essential to protect data with up-to-date antivirus software. He anti virus software it is an essential tool for protecting cloud servers from potential threats, including malware, viruses, and other types of malicious software.

Antivirus software works by scanning your system for known and unknown threats, and removing any malware that is detected. However, it's important to keep in mind that viruses and other malware evolve and change over time, which means antivirus software must be updated regularly to make sure you can detect and eliminate threats most recent.

It is important to choose a good antivirus software that is suitable for the cloud server and the type of data being stored. In addition, it is essential that antivirus software is regularly updated to ensure that it is up to date with the latest threats and vulnerabilities.

Another important measure is to make sure that your antivirus software is properly configured and running regularly. This can include setting up regular automatic scans, running security updates, and setting up alerts to notify the security team of potential threats.

Additionally, in GCP It is possible to use different security tools, such as Cloud Armor, which works at the application layer level of the web services that we have implemented on our server, providing a extra layer of protection against possible threats. On the other hand, intrusion detection tools can be used, such as Cloud IDS, for detect possible attacks before they cause damage.


3. Back up and restore data

Another crucial measure to ensure the cloud server security it is make a security copy which is a data restoration on regular basis. Backups allow companies recover lost or damaged data in the event of a system outage or failure, which can be caused by various reasons, such as a cyber attack, hardware failure, human error, among others.

To ensure adequate data protection, it is important to perform back up frequently. This may depend on the type of data and how often the data is updated, but daily or weekly backups are generally recommended. In addition, it is important to store backup copies in a secure location, outside of the cloud server, to prevent data loss in the event of a system failure.

It is also important to regularly test the restoreability of your backups to ensure that they can be recover data effectively in the event of an interruption or failure. It is essential that the Operations team is trained to restore data efficiently and quickly in the event of an incident.

Also, it's important to note that backups are not a complete security solution by themselves, but rather a preventative measure. It is necessary to adopt other security measures, such as those mentioned above, to prevent failures from occurring in the first place.


4. Use security monitoring and analysis tools

When using a cloud serverIt is important to have tools security monitoring and analysis to detect and prevent possible cyber attacks.

Monitoring tools can help monitor the network traffic and the real time server usage, which can help detect suspicious patterns and potential attack attempts. This may include identifying unusual traffic patterns or detecting malicious activity such as failed login attempts or attempts to exploit known vulnerabilities.

On the other hand, the security analysis tools can help identify vulnerabilities in the system and in applications hosted on the server. This may include penetration testing to identify potential weaknesses in the system, identifying known vulnerabilities in the software used, and conducting code analysis to detect potential security breaches.

GCP offers different tools to monitor activity in the cloud, such as Cloud Logging which is a cloud monitoring. In addition, security analysis tools can be used, such as Cloud Security Scanner, to detect possible vulnerabilities in the different resources implemented as well as the bad parameters applied in our servers.


5. Use updated software

It is important to use cloud-specific software that adapts to the needs of the company and that is updated regularly with the latest patches and security updates. This includes the aforementioned antivirus software.


6. Establish access control policies

It is essential to establish access control policies based on roles (RBAC) and configure the permissions of the users so that they can only access the necessary resources. This can help prevent unauthorized access and reduce the risk of cyber attacks.

In GCP, You can use Cloud Identity and Access Management (IAM) to manage roles and access permissions to cloud resources. IAM allows you assign roles to users and groups, and these roles define the permissions they have to access and manage the resources.

In addition, it is important to keep your server software up to date and regularly apply security updates. GCP offers tools like the system update manager (OS patch management) to help you keep your servers up to date.

It is also advisable to use security monitoring and analysis tools to quickly detect and respond to potential security threats. GCP offers tools like Cloud Security Command Center to monitor and analyze the security of your cloud resources.


7. Traffic of interest

Another important measure to protect cloud servers is to properly configure the network firewalls to limit incoming and outgoing network traffic. The different clouds offer a built-in firewall that allows you to control the incoming and outgoing network traffic of your VM instances.

In these scenarios, the firewall is a security tool that is used to control incoming and outgoing network traffic from a server or a network. In Google Cloud Platform (GCP), you can use the firewall to protect your virtual machine instances (VMs) and other network resources running in the cloud.

The GCP firewall is configured through firewall rules that specify what network traffic is allowed and what traffic is blocked. These rules can be configured at the network level (network-level firewall rules) and at the instance level (instance-level firewall rules).

Firewall rules can be based on different criteria, such as the source or destination IP address, the protocol, and the port used. For example, you can configure a firewall rule that allows HTTP traffic (port 80) from any incoming IP address to your VM instance.

It is important to remember that the firewall is not a complete security solution on its own, and that it must be used in conjunction with other security measuressuch as role-based authentication and authorization, security monitoring and analysis, and regular software updating.
