Monitor and control incoming and outgoing network traffic based on predefined security rules. Its purpose is to prevent unauthorized access to a system and protect data from external threats.
Firewall sangat penting untuk melindungi sistem dari akses yang tidak sah, menyaring lalu lintas berbahaya, dan berfungsi sebagai garis pertahanan pertama dalam keamanan jaringan. Firewall juga membantu memantau aktivitas jaringan secara real-time, mencegah kebocoran data, dan mengontrol akses berdasarkan kebijakan tertentu. Memastikan bahwa hanya lalu lintas yang diizinkan yang dapat masuk atau keluar dari jaringan.
Firewall rule management and periodic tuning to ensure optimal performance and security.
Real-time firewall monitoring and incident handling to protect networks from cyber attacks.
Provide periodic security reports for audits and ensure compliance with industry standards.
Regular firmware updates, patching, and health checks keep your firewall reliable and up-to-date.
The firewall receives incoming or outgoing traffic and determines the source and destination zones (e.g., WAN, LAN, DMZ). It identifies the interface where the packet entered the network.
The packet is checked against configured firewall rules. The firewall evaluates parameters such as source IP, destination IP, port numbers, protocols, and user identity (if applicable).
Next-Generation Firewalls (NGFW) perform deep packet inspection (DPI) to detect malware, block unauthorized applications, and enforce content filtering or SSL decryption as needed.
The firewall makes a decision to allow, block, or reject the traffic. Actions are logged for auditing and, if configured, alerts are sent to administrators or SIEM systems for further analysis.
