As noted in the document that Tagir shared, "Scanning Threat Detection can optionally react to an attack by shunning the attacker IP. This makes Scanning Threat Detection the only subset of the Threat Detection feature that can actively affect connections through the ASA."
So we can prevent the traffic from establishing bogus connections via the syn flood method using the command:
Assuming you mean "SYN flood" then yes - the Cisco IPS sensor covers that attack type. Here is a specific link documenting the IPS signature that covers that attack. When you say "etc" that could mean just about anything so I can't answer that precisely.
Please note that the classic Cisco IPS sensor module for the older ASA 5500 series is no longer sold (since last year).
Cisco will sell you a classic IPS module for the new 5500-X series if you really insist on one but you would be much better served by the ASA with Firepower Services, an option when purchasing or configuring an ASA 5500-X series. That includes the superior Next Generation IPS services acquired last year when Cisco purchased Sourcefire.
(And, yes, the IPS license there will also prevent SYN flood attacks.)
