What are the 7 security tips of GCP network security? GCP implements comprehensive security standards to ensure and preserve the security of its infrastructure. The GCP network security blog delivers a list of 7 security tips to help protect your GCP network. Read below.
7 Security Tips of GCP Network Security
A Strong Firewall
GCP strictly enforces network security rules. Also, the network firewall is an important component of security protection.
The GCP network firewall is in the form of a Linux Kernel Packet Filter (Netfilter) function. It separates the Internet port of the GCP network from the internal network.
Strict control is over all packets that enter or exit the GCP network through specific ports and protocols. You can also implement your firewall with GCP.
IP address filtering
GCP strongly protects its IP address space. Only IP addresses from assigned subnets are to access GCP services. This is through IP address filtering on GCP’s edge routers.
Only the GCP network firewall is to access the GCP network and connect to internal IP addresses. Therefore, only trusted IP addresses can access the GCP network.
If an IP address is for malicious purposes, we will invalidate it immediately. The firewall does not allow traffic from invalid IP addresses to enter or exit the GCP network through it. The firewall is a key part of the security protection of GCP.
A Secure Transport Mechanism
GCP uses a combination of software and hardware to protect the transport layer, including encryption and compression technologies such as TLS, SSH, and SSL/TLS. This ensures that confidential information is not compromised in transit, whether it is to or from GCP.
Encryption is to protect data in transit, including traffic between the GCP network and your computer, and traffic between GCP services. Encryption is on a digital certificate signed by a trusted certificate authority.
The certificate is to an IP address of the GCP network edge routers. Also, the encryption key used is set to be at regular intervals each time the certificate is renewed.
A Secure Transport Mechanism
The GCP network uses a secure transport mechanism to ensure that traffic between GCP services is encrypted and authenticated. The following are the supported protocols:
- Encrypted Transport Layer Security (TLS)
- Secure Shell (SSH)
- Secure Socket Layer/Transport Layer Security (SSL/TLS)
- Transport Layer Security (TLS)
- Secure Copy Protocol (SCP)
Use Multiple Authentication Methods
GCP uses a combination of software and hardware to protect the authentication layer, including two-factor authentication (2FA) and smart cards. 2FA is the 2nd authentication method.
The second factor is generally a mobile phone. So, the security operations center sets up a one-time password on your account, which you must enter before accessing your account.
A Centralized Access Control Mechanism
All GCP users are to use a GIP to access the GCPD network. This mechanism protects the security of your account.
Access control is through the centralized access control mechanism. Only authorized users can access GCP services through network access points.
Strong Password Policy
Passwords are the most common and also the easiest way to steal user identity information. Therefore, GCP strictly enforces strong password policies.
The GCP network allows only alphanumeric characters, with a minimum length of 6 characters and a maximum length of 16 characters. Also, the password must be at least once every 90 days. enforcement of the GCP account password policy
Conclusion
To sum up, we recommend that you enable the firewall, use multiple authentication methods, and use strong passwords. This enables you to protect GCP against unauthorized access and malicious attacks.
