The Singapore Cloud Server firewall is the first line of defense for network security and plays a very critical role in helping the Singapore Cloud Server reduce potential risks and threats and protect the network and the Singapore Cloud Server from malicious activities. There are many types of firewalls in Singapore cloud servers. Different types of protection walls provide different levels of security protection and different types of threats they protect against. Common Singapore cloud server firewall types mainly include the following categories!

　　Network layer firewall

　　This kind of firewall is located at the boundary of the network and filters the data traffic in and out of the server. It can control traffic based on source and destination IP addresses, ports and protocols, as well as defend against DDoS attacks and more.

　　Host firewall

　　A software firewall running on a server to protect a single host or server. It monitors and controls network communications for specific applications, blocking unwanted access.

　　Web application firewall (WAF)

　　Specific firewall for web applications, used to protect applications from web attacks, such as SQL injection, cross-site scripting attacks (XSS), etc.

　　Intrusion detection system (IDS) and intrusion prevention system (IPS)

　　IDS monitors server traffic and detects potential attacks. IPS can proactively block and respond to attacks, providing more active protection.

　　Cloud firewall

　　Firewall designed for cloud environments to protect cloud infrastructure and virtual machines from network attacks.

　　Application isolation technology

　　Use containerization or virtualization technology to isolate different applications in independent environments to reduce the attack surface.

　　Anti-virus and malware protection

　　The protection wall integrates anti-virus and malware detection functions to prevent the spread of malicious code.

　　Packet filtering

　　According to predefined rules, filter the data packets entering and leaving the server to block unnecessary or potentially malicious data traffic.

　　DNS firewall

　　Monitor and filter domain name resolution requests to prevent DNS hijacking and domain name spoofing attacks.

　　The correct use of firewalls can protect the Singapore cloud server network from attacks, control access to the Singapore cloud server, implement security policies, block malicious traffic, intrusion detection and prevention, application control, network segmentation and isolation, and defense against network attacks. Log monitoring and more. Users need to choose the appropriate firewall type or combination based on the characteristics and application scenarios of the Singapore cloud server to ensure the security and reliability of the Singapore cloud server. Regularly maintaining and updating firewall rules to ensure they can adapt to changing security threats is also an important measure.
