The Intrusion Detection System (IDS) helps identify patterns in network packets that may indicate an attack on the endpoint.

The Intrusion Detection System (IDS) can help prevent the following well-known intrusions:

Intrusion	Description
Too Big Fragment	A Denial of Service attack where a hacker directs an oversized TCP/UDP packet at a target endpoint. This can cause a buffer overflow, which can freeze or restart the endpoint.
Ping of Death	A Denial of Service attack where a hacker directs an oversized ICMP/ICMPv6 packet at a target endpoint. This can cause a buffer overflow, which can freeze or reboot the endpoint.
Conflicted ARP	A type of attack where a hacker sends an Address Resolution Protocol (ARP) request with the same source and destination IP address to a targeted endpoint. The target endpoint continually sends an ARP response (its MAC address) to itself, causing the endpoint to freeze or crash.
SYN Flood	A Denial of Service attack where a program sends multiple TCP synchronization (SYN) packets to the endpoint, causing the endpoint to continually send synchronization acknowledgment (SYN/ACK) responses. This can exhaust endpoint memory and eventually crash the endpoint.
Overlapping Fragment	Similar to a Teardrop attack, this Denial of Service attack sends overlapping TCP fragments to the endpoint. This overwrites the header information in the first TCP fragment and may pass through a firewall. The firewall may then allow subsequent fragments with malicious code to pass through to the target endpoint.
Teardrop	Similar to an overlapping fragment attack, this Denial of Service attack deals with IP fragments. A confusing offset value in the second or later IP fragment can cause the operating system on the receiving endpoint to crash when attempting to reassemble the fragments.
Tiny Fragment Attack	A type of attack where a small TCP fragment size forces the first TCP packet header information into the next fragment. This can cause routers that filter traffic to ignore the subsequent fragments, which may contain malicious data.
Fragmented IGMP	A Denial of Service attack that sends fragmented IGMP packets to a target endpoint, which cannot properly process the IGMP packets. This can freeze or slow down the endpoint.
LAND Attack	A type of attack that sends IP synchronization (SYN) packets with the same source and destination address to the endpoint, causing the endpoint to send the synchronization acknowledgment (SYN/ACK) response to itself. This can freeze or slow down the endpoint.
