The various suspicious patterns for which the Cisco Tetration platform looks in the current release are:
+ Shell code execution: Looks for the patterns used by shell code.
+ Privilege escalation: Watches for privilege changes from a lower privilege to a higher privilege in the process lineage tree.
+ Side channel attacks: Cisco Tetration platform watches for cache-timing attacks and page table fault bursts.
Using these, it can detect Meltdown, Spectre, and other cache-timing attacks.
+ Raw socket creation: Creation of a raw socket by a nonstandard process (for example, ping).
+ User login suspicious behavior: Cisco Tetration platform watches user login failures and user login methods.
+ Interesting file access: Cisco Tetration platform can be armed to look at sensitive files.
+ File access from a different user: Cisco Tetration platform learns the normal behavior of which file is accessed by which user.
+ Unseen command: Cisco Tetration platform learns the behavior and set of commands as well as the lineage of each command over time. Any new command or command with a different lineage triggers the interest of the Tetration Analytics platform.

Dynamic ARP inspection (DAI) is a security feature that validates ARP packets in a network. It intercepts, logs, and discards ARP packets with invalid IP-to-MAC address bindings. This capability protects the network from certain man-in-the-middle attacks. After enabling DAI, all ports become untrusted ports.
