In today's highly developed information technology, information security has become an aspect that enterprises attach great importance to.
According to IDG statistics, 97% of the world's top 500 enterprises have had network security incidents. The losses caused to the global economy by network security problems reached 450 billion US dollars, an increase of 18% over the previous year, and it is estimated that this figure will reach 1 trillion US dollars by 2021. Therefore, no matter large or small enterprises, once they suffer from network attacks, their consequences and losses will be huge. So set firewall Protecting the security of corporate networks has become an effective choice for enterprise security because:
1) Firewall can effectively prevent unnecessary network attacks
After the firewall filtering, only those data packets that meet the security policy can enter and exit the company network. Any other invalid or attack packets are blocked outside the firewall, effectively protecting the security of the company network.
2) Firewall can prevent internal information leakage
By using the firewall to divide the internal network, the key network segments of the internal network can be isolated, thus limiting the access to sensitive data, and avoiding the loss of enterprise intellectual property rights caused by the leakage of internal data information.
3) Monitor and audit network access and access
Through the firewall's audit log, you can effectively monitor and monitor abnormal access, thus preventing improper access behavior.
Firewall is the security guarantee of enterprise network, and its effectiveness is based on the establishment of a set of firewall security policies to meet the business needs of enterprises.
In IT outsourcing services, the application policy based firewall (NGFW) is gradually used and has a good effect because of its application and content filtering function.
