Introduction to cisco-secure-client-linux64-5.0.05040-predeploy-k9.tar.gz Software
The cisco-secure-client-linux64-5.0.05040-predeploy-k9.tar.gz file contains Cisco’s enterprise-grade VPN solution for 64-bit Linux systems, designed for centralized deployment in organizational networks. As part of Cisco Secure Client 5.0 release series (formerly AnyConnect Secure Mobility Client), this predeployment package enables IT administrators to distribute VPN configurations and security policies through automated software management systems.
This Q2 2024 maintenance release focuses on hardening cryptographic implementations while maintaining backward compatibility with Cisco ASA 5500-X series firewalls (9.12.4+) and Firepower Threat Defense (FTD) 7.2.1+ platforms. The 5.0.05040 build corresponds to Cisco’s April 2024 security advisory bundle addressing CVE-2024-20356 vulnerability in DTLS session handling.
