NSA urges businesses to adopt zero trust for network security
The National Security Agency this week detailed recommendations for businesses to secure their network infrastructure against attacks, giving safe configuration tips for commonly used networking protocols and urging the use of basic security measures for all networks.
The NSA's report highlighted the importance of zero trust principles for network security, but the bulk of it covers specific steps network administrators should take to keep their infrastructure safe from compromise. Configuration tips for network admins include the use of secure, frequently changed passwords for all administrative accounts, limiting login attempts, and keeping potentially vulnerable systems patched and up-to-date. The report also describes safe configurations for SSH (secure shell), HTTP and SNMP (simple network management protocol).
