Firewalls are used to restrict traffic entering or leaving a network by creating rules that determine what is permitted. Intrusion detection systems identify suspicious activity on a network by monitoring traffic patterns. Authentication protocols verify user identities before allowing access to resources. Encryption scrambles data so it is unreadable without the proper key. VPNs create secure connections between computers over an insecure public network such as the internet. Antivirus software scans files for known viruses and blocks them from entering the system. Honeypots are decoy systems designed to attract attackers away from critical resources while recording their attempts at entry or attack. Access control lists define who can access specific resources on a network and what they can do with them once they gain access.
These and other security features are necessary in today's world where cyber attacks are becoming increasingly commonplace. Organizations must take steps to protect their valuable assets and data from malicious actors by implementing robust network security measures that utilize these features when possible.
