Securing the Network

Effective network security is crucial for protecting data and resources in any organization. It involves a multi-layered strategy where different technologies work in concert to defend against various cyber threats. At the forefront of this strategy are the key elements of firewalls, access control lists (ACLs), intrusion detection systems (IDSs) and intrusion prevention systems (IPSs), and security information and event management (SIEM).

Within the network, firewalls act as the first line of defense, monitoring and filtering incoming and outgoing network traffic. They use an ACL in which the only default rule is “deny all.” Allow rules need to be created to allow any traffic through. While ACLs act as barriers based on specific criteria, IDSs and IPSs further enhance security by detecting and preventing suspicious activities in real time. The ACL, IDS, and IPS technologies work together to create a robust security perimeter.
