Securing Devices -Passwords Passwords are the first layer of securing devices. As computing power has increased, the ability of bad actors to more quickly brute force passwords. A previously compromised password is always considered instant for brute force attack. What do we do? Never reuse passwords. Change passwords that have been compromised immediately. Where possible, use 2-factor authentication. Specifically - use hard tokens or soft tokens. SMS is the least secure 2FA. Verizon confidential and proprietary. Unauthorized disclosure, reproduction or other use prohibited.
Securing Devices -Access Control In addition to passwords/accounts, limiting access to systems from specific resources is critical. Limiting device control to specific interfaces is a best practice. Access Control Lists (ACLs) are used in network elements to assign access based on source IP addresses, ports/protocols. ACLs will secure network elements directly by limiting access to the management of the device. ACLs applied against the control plane or management interface. ACLs can also secure networks by limiting the type(s) of traffic that are allowed through the network. ACLs applied to interfaces to permit/deny specific traffic.
