![]() ![]() This is a record on the CVE List, which provides common identifiers for publicly known cybersecurity vulnerabilities. Necessarily indicate when this vulnerability wasĭiscovered, shared with the affected vendor, publicly The CVE ID was allocated or reserved, and does not The list is not intended to be complete.ĭisclaimer: The record creation date may reflect when IPNetSentryX cannot be removed completely from Mac, there are still some files and components leaving on the computer. Firewall and intrusion detector for Mac OS X includes Ethernet bridging, AirPort configuration, detailed logging and bandwidth accounting. Note: References are provided for the convenience of the reader to help distinguish between vulnerabilities. You can also specify relative offsets (+/-) from the start of the previously matched text.Sustworks IPNetSentryX and IPNetMonitorX allow local users to sniff network packets via the setuid helper applications (1) RunTCPDump, which calls tcpdump, and (2) RunTCPFlow, which calls tcpflow. IPNetSentryX supports flexible text matching for data content filtering. The tools included with IPNetSentryX can be used to examine network traffic to identify packet characteristics for filtering. IPNetSentryX's URL keyword matching feature can restrict web access to a collection of related web sites or pages that don't easily correspond with any server address.īlocked web pages are indicated explicity in the users web browser. Preliminary testing shows ".edu" web sites come up normally, while others are blocked by IPNetSentry. So we might first search for packets to port 80 (HTTP) with the keyword "GET" in the first few bytes, and then block requests that do not have URL keyword ".edu". Using the TCP Dump tool (with TCP Flow selected) shows a typical web page access looks like this: To monitor network traffic, IPNetSentryX includes a tiny server application named 'LoadNKE' that must run as suid root. So you need to first separate packets that are URL references, and then check for URL keyword ".edu". IPNetSentryX takes the personal computer view that the user should normally be in control of their computer, so tries to minimize the disruption of asking the user to prove they are authorized to perform the requested operation. If you just blocked all HTTP traffic that didn't contain the URL keyword ".edu" that would be too much because many packets are not URL references. IPNetSentryX and IPNetMonitorX, network monitoring tools from Sustworks, contain flaws that could allow an unauthorized local user to sniff the network or. A public student terminal might allow access only to web sites from the ".edu" top level domain for example. Suppose you wanted to restrict access to a specific collection of web sites and block all others. ![]() ![]() ![]() This is particularly important for Mac users who have cable modem, DSL, or another high-speed Internet service where connections can be maintained and left unattended for hours (or days) at a time. You might choose URLs with the keyword "xxx", or keywords for servers that supply website advertising images. IPNetSentryX overview IPNetSentry is a simple and intelligent security application which protects your Mac from outside Internet intruders. I picked "/music/store/" as a harmless example to demonstrate the concept. Notice by matching with the relationship "a=A", we can match upper or lower case letters. You can now access most of Apple's web site normally, but when you hit pages with "/music/store/" in the URL, your web browser will display an image similar to the following: You could specify a set of rules like this: You notice that such pages have URLs of the form: Suppose you wanted to block access to a set of web pages about the Apple Music Store. IPNetSentryX's URL Keyword feature allows you to specify web pages by matching keywords in the referring URL. If you wanted to block access to a specific web server, you could specify the corresponding IP address, but what if you want to block access to a collection of related web pages that may not correspond to a single server? You would like to block access to certain web pages. Application Note 1005 Using IPNetSentryX to Block Web Page Access ![]()
