#snsinstitutions #snsdesginthinkers #designthinking A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predefined security rules. It acts as a barrier between a trusted internal network and untrusted external networks such as the internet. Firewalls help protect computers and networks from unauthorized access, malware, hackers, and cyber threats. They can be hardware-based, software-based, or a combination of both. By filtering data packets, firewalls allow safe communication while blocking suspicious or harmful traffic. Firewalls are widely used in homes, businesses, schools, and organizations to maintain cybersecurity and data privacy. Modern firewalls provide advanced features such as intrusion detection, content filtering, virtual private network (VPN) support, and application control. They play an important role in preventing cyberattacks, safeguarding sensitive information, and ensuring secure online activities. Regular updates and proper configuration of firewalls are essential to maintain effective network protection.
