Proxy 1.11 – Web Interception Proxy. Developer Tools Mac AppStore Proxy. Proxy is a HTTP, intercepting proxy for Mac OS X. This tool is designed from. Returns a proxy instance for the specified interfaces that dispatches method invocations to the specified invocation handler. IllegalArgumentException will be thrown if any of the following restrictions is violated. All of Class objects in the given interfaces array must represent interfaces, not classes or primitive types.; No two elements in the interfaces array may refer to identical Class. This may take a bit of time and if broken down a bit will be easier to manage for all of us. So here goes we will start with Intercepting Proxies: Intercept Proxies - An intercept proxy is a tool which combines a proxy server (the server in this case is the application not a physical server) with a gateway. It sits between your browser and your. For IPv6 interception use TPROXY version 4. /etc/sysctl.conf Configuration # Controls IP packet forwarding net.ipv4.ipforward = 1 # Controls source route verification net.ipv4.conf.default.rpfilter = 0 # Do not accept source routing net.ipv4.conf.default.acceptsourceroute = 0. Squid Configuration File. Interception Caching packet redirection with Cisco routers using policy routing (NON WCCP) by John Saunders. This works with at least IOS 11.1 and later. If your router is doing anything more complicated that shuffling packets between an ethernet interface and either a serial port or BRI port, then you should work through if this will work for you.
Nowadays, most companies control the Internet access of employees through the use of a proxy.
BlueCoat, recently acquired by Symantec, is a leader company in Web Security Services. Regarding proxy appliances, BlueCoat has no competitors.
One of the biggest advantages offered by proxy appliances is the ability to inspect SSL traffic. This is very useful to detect suspicious payloads in requests, downloads of malicious software, control possible leaks of information, etc
In this post we are going to explain how to configure a ProxySG S400-30 appliance (SGOS 6.7.3.1) to be able to inspect the company SSL traffic. Keycue 9 78.
Create the certificate used to intercept SSL traffic
From the administration web console the first thing we should do is create a new keyring. This keyring is the SSL certificate that will be presented to users when browsing HTTPS sites.
For that, navigate to “Configuration > SSL > Keyrings” and click on “Create”:

Click on the new keyring created and press “Edit”. In the “Certificate Signing Request” section, click on “Create”:
Fill in the data of the certificate that will be shown to the users. It is important to take into account the CN field and the encryption algorithm.
Once the CSR is created, click on Edit again and copy the base64 code to a .txt file and rename it with extension .csr:
Once the CSR is obtained, it must be signed by the Root CA (Certificate Authority) of our company PKI. This is really important because our employees web browsers have to trust in this certificate, since users already trust in our company Root CA they will trust in the proxy certificate if it is signed by the Root CA.
When signing the CSR, we must use the SubCA template because the certificate to be installed in the proxy must be able to issue certificates emulating the certificates of the HTTPS websites visited by the users.
To sign the CSR we can use the following command from our Active Directory Server:
certreq.exe -attrib 'CertificateTemplate:SubCA' -submit <CSR_file> |
Once signed and obtained the inspection certificate, it must be converted to base64 .cer format in order to be imported into the proxy keyring. To convert it to base64 you can use the native Windows “certutil” tool. Ex:
