However, the firewall considers this act only as access to an allowed port.Note that: The Security log will report when the firewall identifies and blocks an intrusion.
For example, the ge-0/0/2.0 as ingress (sniff) and the ge-0/0/2.100 as egress interfaces are displayed in the logs to show the source interface as ge-0/0/2.100.
Many computer users have encountered tools that monitor dynamic system behaviour in the form of anti-virus (AV) packages.
While AV programs often also monitor system state, they do spend a lot of their time looking at who is doing what inside a computer – and whether a given program should or should not have access to particular system resources.
A typical attribute of intrusions is their apparent legitimacy and it is difficult to uncover such traffic and filter it simply by traffic rules.
Let us use Denial of Service intrusion as an example — too many connections are established on a port to use up the system resources of the server application so that no other users can connect.
In theory, a computer user has the ability to detect any such modifications, and the HIDS attempts to do just that and reports its findings.
Ideally a HIDS works in conjunction with a NIDS, such that a HIDS finds anything that slips past the NIDS.Besides such activities as dynamically inspecting network packets targeted at this specific host (optional component with most software solutions commercially available), a HIDS might detect which program accesses what resources and discover that, for example, a word-processor has suddenly and inexplicably started modifying the system password database.Similarly a HIDS might look at the state of a system, its stored information, whether in RAM, in the file system, log files or elsewhere; and check that the contents of these appear as expected, e.g. One can think of a HIDS as an agent that monitors whether anything or anyone, whether internal or external, has circumvented the system's security policy.Blacklists may also include IP addresses of legitimate clients or servers.Therefore, you can set the same actions for blacklists as for detected intrusions.The basic IDP configuration involves the following tasks: SRX Series Services Gateways can be deployed in inline tap mode and sniffer mode (only on SRX5400, SRX5600, and SRX5800 devices).
