  • Enhancing the security of access layer switches

    Enhancing the security of access layer switches

    By enabling ACLs on your Layer 3 switches, you can control which devices and users can access your network resources and block unwanted or malicious traffic. Access control lists (ACLs) are rules that filter traffic based on source and destination IP addresses, protocols, and ports. Modern switches offer several security mechanisms—such as port security, BPDU guard, root guard. Cisco SwitchIn today's interconnected world, enterprise networks face constant threats from cyberattacks. Here are. The short answer: IOS software updates are not required to maintain compliance with SOC2, ISO 27001, or PCI DSS on Cisco access-layer switches. Compliance is achievable — and fully defensible in an audit — through deliberate LAN configuration hardening: enforcing least privilege, strong. At the same time as providing simple uncomplicated network access for users, the access layer provides the first line of security defense for the network, provide service differentiation based upon management policies and, providing power to support the deployment of specialized devices.
