jnxJsScreenMonSynAttk OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The SYN (TCP connection request) attack is a common denial
of service (DoS) technique characterized by the following
pattern:
- Using a spoofed IP address not in use on the Internet,
an attacker sends multiple SYN packets to the target machine.
- For each SYN packet received, the target machine allocates
resources and sends an acknowledgement (SYN-ACK) to the source
IP address. This can cause the target machine to allocate
resources for more than 3 minutes to respond to just one i
SYN attack, hence wasting resources.
This attribute records the number of SYN attacks."
::= { jnxJsScreenMonEntry 3 }
jnxJsScreenMonTearDrop OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Teardrop attacks exploit the reassembly of fragmented IP
packets. In the IP header, one of the fields is the fragment
offset field, which indicates one of the fields is the fragment
offset field. It indicates the starting position of the data
contained in a fragmented packet relative to the data of the
original unfragmented packet. When the sum of the offset and
size of one fragmented packet differ from that of the next
fragmented packet, the packets overlap. The server attempting
to reassemble the packet can crash, especially if it is running
an older operating system that has this vulnerability.
When this option is enabled, the security device detects this
discrepancy in a fragmented packet and drops it and this
attribute counts the number of packets dropped."
::= { jnxJsScreenMonEntry 4 }
jnxJsScreenMonSrcRoute OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"IP source route options can be used to hide their true address
and access restricted areas of a network by specifying a
different path. The security device should be able to either
block any packets with loose or strict source route options
set or detect such packets and then record the event for the
ingress interface.
This attribute records either the loose source route option or
strict source route attack packets."
::= { jnxJsScreenMonEntry 5 }
jnxJsScreenMonPingDeath OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The maximum allowable IP packet size is 65,535 bytes,
including the packet header (typically 20 bytes long).
An ICMP echo request is an IP packet with a pseudo header,
which is 8 bytes long. Therefore, the maximum allowable
size of the data area of an ICMP echo request is 65,507
bytes.
However, many ping implementations allow the user to specify
a packet size larger than 65,507 bytes. A grossly oversized
ICMP packet can trigger a range of adverse system reactions
such as denial of service (DoS), crashing, freezing, and
rebooting.
When the Ping Death option is enabled, the device detects and
rejects such oversized and irregular packet sizes even when
the attacker hides the total packet size by purposefully
fragmenting it.
This attributes counts the ping of death attack packets."
::= { jnxJsScreenMonEntry 6 }
jnxJsScreenMonAddrSpoof OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"One method to gain access to a restricted network is to insert
a bogus source address in the packet header to make the packet
appear to come from a trusted source. This technique is called
IP spoofing. The mechanism to detect IP spoofing relies on
route table entries.
For example, if a packet with source IP address 10.1.1.6 arrives
at port eth3, but the device has a route to 10.1.1.0/24 through
port eth1. IP spoofing checking notes that this address arrived
at an invalid interface as defined in the route table. A valid
packet from 10.1.1.6 can only arrive via eth1, not eth3. The
device concludes that the packet has a spoofed source IP address
and discards it.
This attribute records the address spoofing attack packets."
::= { jnxJsScreenMonEntry 7 }
jnxJsScreenMonLand OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A combined SYN attack with IP spoof is referred to as
Land attack. A Land attack occurs when an attacker sends
spoofed SYN packets containing the IP address of the victim as
both the destination and source IP address. The receiving
system responds by sending the SYN-ACK packet to itself,
creating an empty connection that lasts until the idle timeout
value is reached. Flooding a system with such empty connections
can overwhelm the system, causing a DoS.
This attribute records the land attack packets."
::= { jnxJsScreenMonEntry 8 }
jnxJsScreenMonIcmpFlood OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An ICMP flood typically occurs when ICMP echo requests overload
its victim with so many requests that it expends all its
resources responding until it can no longer process valid network
traffic. With the ICMP flood protection feature enabled, and a
threshold set. If the threshold exceeded, the system invokes the
flood attack protection feature.
The default threshold value is 1000 packets per second. If the
threshold is exceeded, the security device ignores further
ICMP echo requests for the remainder of that second plus the
next second as well.
This attribute records the ICMP flood attack packets."
::= { jnxJsScreenMonEntry 9 }
jnxJsScreenMonUdpFlood OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"UDP flooding occurs when an attacker sends IP packets containing
UDP datagrams with the purpose of slowing down the victim to the
point that it can no longer handle valid connections. With the
UDP flood protection feature enabled, a threshold can be set which
once exceeded, the system invokes the UDP flood attack protection
feature.
The default threshold value is 1000 packets per second.
If the number of UDP datagrams from one or more sources to a
single destination exceeds this threshold, security device
ignores further UDP datagrams to that destination for the
remainder of that second plus the next second as well.
This attribute records the UDP flood attack packets."
::= { jnxJsScreenMonEntry 10 }
jnxJsScreenMonWinnuke OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"WinNuke is a DoS attack targeting any computer on the internet
running Windows. The attacker sends a TCP segment, usually to
NetBIOS port 139 with the urgent (URG) flag set, to a host with
an established connection. This introduces a NetBIOS fragment
overlap, which causes many machines running Windows to crash.
This attributes counts the netbios attack."
::= { jnxJsScreenMonEntry 11 }
jnxJsScreenMonPortScan OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A port scan occurs when one source IP address sends IP packets
containing TCP SYN segments to a defined number of different
ports at the same destination IP address within a defined interval.
The purpose of this attack is to scan the available services in
the hope that at least one port will respond, thus identifying
a service of the target. The device should internally log the
number of different ports scanned from one remote source.
This attribute records the port scan attempt attack packets."
::= { jnxJsScreenMonEntry 12 }
jnxJsScreenMonIpSweep OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"An address sweep occurs when one source IP address sends a
defined number of ICMP packets to different hosts within a
defined interval. The purpose of this attack is to send ICMP
packets, typically echo requests, to various hosts in the
hope that at least one replies, thus uncovering an address of
the target. The device internally log the number of ICMP packets
to different addresses from one remote source.
This attributes records the address sweep attemp attack packets."
::= { jnxJsScreenMonEntry 13 }
jnxJsScreenMonSynFrag OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"IP encapsulates a TCP SYN segment in the IP packet that initiates
a TCP connection. The purpose is to initiate a connection and to
invoke a SYN/ACK segment response. The SYN segment typically does
not contain any data since the IP packet is small and there is
no legitimate reason for it to be fragmented. A fragmented SYN
packet is anomalous and is suspectful. To be cautious, it might
be helpful to block such these fragments from entering the
protected network.
When the syn fragmentation check is enable, the security device
detects and drops the packets when the IP header indicates that
the packet has been fragmented while the SYN flag is set in the
TCP header.
This attributes records the detection of the SYN fragments."
::= { jnxJsScreenMonEntry 14 }
jnxJsScreenMonTcpNoFlag OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A normal TCP segment header has at least one flag control set.
A TCP segment with no control flags set is an anomalous event.
Operating systems respond to such anomalies in different ways.
The response, or even lack of response, from the targeted device
can provide a clue as to the target's OS type.
When this option is enabled, if the device discovers such a
header with a missing or malformed flags field, it drops the
packet.
The attribure records the detection of TCP without flag set packets."
::= { jnxJsScreenMonEntry 15 }
jnxJsScreenMonIpUnknownProt OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"According to RFC 1700, some protocol types in IP header are
reserved and unassigned at this time. Precisely because these
protocols are undefined, there is no way to know in advance
if a particular unknown protocol is benign or malicious. Unless
your network makes use of a non-standard protocol with reserved
or unassigned protocol number, a cautious stance is to block
such unknown elements from entering your protected network.
When the Unknown Protocol Protection SCREEN option is enabled,
the security device drops packets when the protocol field
contains a protocol ID number of 137 or greater by default.
This attribute records the detection of Unknown protocol
IP packets."
::= { jnxJsScreenMonEntry 16 }
jnxJsScreenMonIpOptBad OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"IP protocol specifies a set of eight options that provide
special routing controls, diagnostic tools, and security.
These eight options can be used for malicious objectives.
Either intentionally or accidentally, attackers sometimes
misconfigure IP options, producing either incomplete or
malformed fields. The misformatting is anomalous and
potentially harmful to the intended recipient.
When the Bad IP Option Protection SCREEN option is enabled,
the security device detects and blocks packets when any IP
option in the IP packet header is incorrectly formatted.
This attributes records the detection of the IP bad option
packets."

These options appear after the destination address in an IP packet
header. When they do appear, they are frequently being put to
some nefarious use. Record option is one of these options that an
attacker can use for reconnaissance or for some unknown but
suspicious purpose
When record IP option is received, the security device
flags this as an network reconnaissance attack and records
the event for the ingress interface.
This attribute records the detection of IP record option

DESCRIPTION
"ICMP provides error reporting and network probe capabilities.
ICMP packets contain very short messages, there is no legitimate
reason for ICMP packets to be fragmented. If an ICMP packet is
so large that it must be fragmented, something has gone amiss.
With the ICMP Fragment Protection SCREEN option enabled, the device
should be able to block any ICMP packet with the More Fragments
flag set, or with an offset value indicated in the offset field.
This attribute counts the ICMP fragment packets."
::= { jnxJsScreenMonEntry 24 }
jnxJsScreenMonIcmpLarge OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only

DESCRIPTION
"ICMP packets contain very short messages, there is no legitimate
reason for ICMP packets to be fragmented.
If an ICMP packet is unusually large, something is wrong. For example,
the Loki program uses ICMP as a channel for transmitting covert
messages. The presence of large ICMP packets might expose a
compromised machine acting as a Loki agent. It might also indicate
some other kind of shifty activity.
When the the Large Size ICMP Packet Protection SCREEN option is enabled,
the device drops ICMP packets with a length greater than 1024 bytes.
This attribute records the detection of large ICMP packets."

jnxJsScreenMonTcpSynFin OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"Both the SYN and FIN control flags are not normally set in the
same TCP segment header. The SYN flag synchronizes sequence
numbers to initiate a TCP connection. The FIN flag indicates
the end of data transmission to finish a TCP connection. Their
purposes are mutually exclusive. A TCP header with the SYN and
FIN flags set is anomalous TCP behavior, causing various
responses from the recipient, depending on the OS.
When block both syn and fin option is enable, the device
drops the packet when it discovers such a header
This attribute records the TCP syn fin both set packet
dropped."
::= { jnxJsScreenMonEntry 26 }
jnxJsScreenMonTcpFinNoAck OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"A FIN scan sends TCP segments with the FIN flag set in an
attempt to provoke a response and thereby discover an active
host or an active port on a host. The use of TCP segments
with the FIN flag set might evade detection and thereby help
the attacker succeed in his or her reconnaissance efforts.
This attributes records the detection of the TCP fin set
without ack bit set packets."

::= { jnxJsScreenMonEntry 28 }
jnxJsScreenMonLimitSessDest OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"The user can limit the number of concurrent sessions
to the same destination IP address. A wily attacker can
launch a distributed denial-of-service (DDoS) attack using
'zombie agents'. Setting a destination-based session limit
can ensure that device allows only an acceptable number of
concurrent connection requests, no matter what the source,
to reach any one host.
The default maximum for destination-based session limit is
128 concurrent sessions.
This attribute records the number of session connection based
on the destination source IP address that exceeds the specified
limit."
::= { jnxJsScreenMonEntry 29 }
jnxJsScreenMonSynAckAck OBJECT-TYPE
SYNTAX Counter64
MAX-ACCESS read-only
STATUS current
DESCRIPTION
"When an authentication user initiates a Telnet or FTP connection,
the user sends a SYN segment to the Telnet or FTP server. The
device intercepts the SYN segment, creates an entry in its
session table, and proxies a SYN-ACK segment to the user. The
user then replies with an ACK segment. At that point, the initial
3-way handshake is complete. The device sends a login prompt to
the user. When a malicisou user does not log in, but instead
continue initiating SYN-ACK-ACK sessions, the firewall session
table can fill up to the point where the device begins rejecting
legitimate connection requests.
When the SYN-ACK-ACK proxy protection option is enabled, after
the number of connections from the same IP address reaches the
SYN-ACK-ACK proxy threshold, the device rejects further
connection requests from that IP address. By default, the
threshold is 512 connections from any single IP address.
The attribute records the detection of SYN ACK ACK attack."

DESCRIPTION
"As packets travels, it is sometimes necessary to break a packet
into smaller fragments based upon the maximum transmission unit
(MTU) of each network. IP fragments might contain an attacker's
attempt to exploit the vulnerabilities in the packet reassembly
code of specific IP stack implementations. When the victim
receives these packets, the results can range from processing
the packets incorrectly to crashing the entire system.
When the block IP framentation flag is enabled, the device blocks
all IP packet fragments that it receives at interfaces bound to
that zone.
This attribute counts the number of block IP fragment packets."
