A network device may install a new receive encryption key, and may start a timer associated with deleting an old receive encryption key. The network device may provide, to another network device, a message identifying the new receive encryption key, and may determine whether packet counts, successfully decrypted with the old receive encryption key, have changed. The first network device may determine whether the timer has expired, and may determine whether the new receive encryption key has successfully decrypted a packet. The first network device may delete the old receive encryption key from the first network device based on the new receive encryption key successfully decrypting a packet.

In some implementations, a device may obtain a log file that includes a plurality of log entries. The device may identify a sequence of log entries, of the plurality of log entries, that are associated with a resource. The device may process the sequence of log entries to generate a sequence of log templates. The device may process the sequence of log templates to identify an anomaly associated with the sequence of log templates. The device may determine, based on the anomaly associated with the sequence of log templates, an anomaly associated with the sequence of log entries. The device may perform, based on the anomaly associated with the sequence of log entries, one or more actions.
