Bog'liq Research on firewall technology and its applicatio4. Application of firewall technology in
computer network security policy
Network security policy refers to the sum of a series of
preventive measures taken in a specific environment to
protect the network from hazards. In addition to strict
management, legal constraints and security education,
advanced technologies like firewalls are relied upon to ensure
system security, mainly including two aspects of technical
means and management measures. Firewall can achieve
access permission, denial, monitoring, by filtering insecure
services, allowing or denying access to certain hosts in the
network, providing access logs, monitoring access, and
achieving centralized security management for the internal
network without the need to set up separate security policies
on each computer, and its application mainly has the
following six points.
4.1. Composite technology applications
Composite technology combines the advantages of both
proxy and packet filtering firewalls, incorporating a number
of security technologies such as IDS and log monitoring,
combined with the actual situation of network security
operations, to ensure that the computer network can respond
quickly when attacked, provide defense services, effectively
stop external attacks, and proactively monitor internal
network information security. Its defense mechanism is the
network security in the form of authentication, using dynamic
filtering to achieve the security of information exchange.
4.2. Monitoring log application
In the process of defending against external network
attacks, the firewall opens full logs and obtains relevant threat
information, categorizes various viruses and Trojans that may
threaten the security of computer networks, and stores them
in the database. Through configuration log, management log,
connection log and view log, analyze the error interception
information in the monitoring log, set default log options,
reset and upgrade the firewall, and intelligently enhance the
interception behavior of the firewall to further improve the
security performance of the computer network.
