+>Either rsyslog or syslog-ng are required to collect syslog messages. The default syslog daemon on version 5 of Red Hat Enterprise Linux, CentOS, and Oracle Linux version (sysklog) is not supported for syslog event collection. To collect syslog data from this version of these distributions, the rsyslog daemon should be installed and configured to replace sysklog.

 ## TLS 1.2 protocol
 To insure the security of data in transit to Azure Monitor logs, we strongly encourage you to configure the agent to use at least Transport Layer Security (TLS) 1.2. Older versions of TLS/Secure Sockets Layer (SSL) have been found to be vulnerable and while they still currently work to allow backwards compatibility, they are **not recommended**.  For additional information, review [Sending data securely using TLS 1.2](../../azure-monitor/platform/data-security.md#sending-data-securely-using-tls-12).
