Proxy Protocol v2 Initiator
Problem this snippet solves: Proxy Protocol v1 related articles have already been posted on DevCentral, but there is no v2 support iRule code available. A customer wanted to support Proxy Protocol v2, so I wrote an iRule code for supporting v2. Proxy protocol for the BIG-IP (f5.com) How to use this snippet: Back-end server must handle Proxy header prior data exchange. Code : when CLIENT_ACCEPTED { # DEBUG On/Off set DEBUG 0 set v2_proxy_header "0d0a0d0a000d0a515549540a" # v2 version and command : 0x21 - version 2 & PROXY command set v2_ver_command "21" # v2 address family and transport protocol : 0x11 - AF_INET (IPv4) & TCP protocol set v2_af_tp "11" # v2 Address Size : 0x000C - 12 bytes for IPv4 + TCP set v2_address_length "000c" # Get TCP port - 2 byte hexadecimal format set src_port [format "%04x" [TCP::client_port]] set dst_port [format "%04x" [TCP::local_port]] # Get Src Address and convert to 4 byte hexadecimal format foreach val [split [IP::client_addr] "."] { append src_addr [format "%02x" $val] } # Get Dst Address and convert to 4 byte hexadecimal format foreach val [split [IP::local_addr] "."] { append dst_addr [format "%02x" $val] } # Build proxy v2 data set proxy_data [binary format H* "${v2_proxy_header}${v2_ver_command}${v2_af_tp}${v2_address_length}${src_addr}${dst_addr}${src_port}${dst_port}"] if { $DEBUG } { binary scan $proxy_data H* proxy_dump log local0.

Introduction Note: This article applies to SSL Orchestrator versions prior to 11.0. If using version 11.0 refer to the article HERE This use case allows you to insert F5 WAF functionality as a Service in the SSL Orchestrator inspection zone. WAFaaS is the ability to insert ASM profiles into the SSL Orchestrator Service Chain for Inbound Topologies. This configuration is specific to a WAF policy running on the SSL Orchestrator device. WAF and SSL Orchestrator consume significant CPU cycles so care should be given when deploying both together. It is also possible to deploy WAF as a service on a separate BIG-IP device, in which case you’d simply configure an inline transparent proxy service. The ability to insert F5’s WAF into the Service Chain presents a significant customer benefit. This guide assumes you already have WAF/ASM profile(s) configured, licensed and provisioned on BIG-IP and wish to add this functionality to an Inbound Topology. In order to run WAF and SSL Orchestrator on the same device you will need an LTM license with SSL Orchestrator as an add-on option. You cannot add a WAF license to an SSL Orchestrator stand-alone license. SSL Orchestrator does not directly support inserting F5 WAF policies into the Service Chain. However, the F5 platform is flexible enough to handle many custom use cases. In this case, the ICAP service configuration exposes a framework that is useful for any number of specialized patterns, including adding a WAF policy to an SSLO service chain. We will configure an ICAP Service and attach the WAF policy to it. Steps: Create ICAP Service Disable Strictness on the Service Disable TCP monitor for the ICAP Pool ICAP Adapt profiles removed from the Virtual Server Application Security Policy enabled and a Policy assigned under Security Step #1: Create ICAP Service Note: These instructions assume an SSL Orchestrator Topology and Service Chain are already deployed and working properly. These instructions simply add WAFaaS to the existing Service Chain. It is entirely possible to create the WAFaaS during the initial Topology creation, in which case you would create the service during the workflow, then make the necessary changes after the topology has been created. From the SSL Orchestrator Guided Configuration click Services then Add Scroll to the bottom, select Generic ICAP Service and click Add Give it a name, WAFaaS in this example For ICAP Devices click Add on the right Enter an IP Address, 198.19.97.1 in this example and click Done. Note: the IP address you use does not have to be the one above. It’s just a local, non-routable address used as a placeholder in the service definition. This IP address will not be used. IP addresses 198.19.97.0 to 198.19.97.255 are owned by network benchmark tests and located in private networks. Scroll to the bottom and click Save & Next. The next screen is the Services Chain List. Click the name of the Service Chain you wish to add WAF functionality to, ssloSC_ServiceChain in this example. Note: The order of the Services in the Selected column is the order in which SSL Orchestrator will pass decrypted data to the device. This can be an important consideration if you want some devices to see, or not see, the actions taken by the WAF Service. Select the WAFaaS Service and click the right arrow to move it to Selected. Click Save. Click Save & Next Click Deploy You should receive a Success message Step #2: Disable Strictness on the Service From the SSL Orchestrator Configuration screen select Services. Click the padlock to Unprotect Configuration. Note: Disabling Strictness on the ICAP Service is needed to modify it and attach the WAFaaS policy. Strictness must remain disabled on this service and disabling strictness on the service has no effect on any other part of the SSL Orchestrator configuration. Click OK to Unprotect the Configuration Step #3: Disable tcp monitor for the ICAP Pool From Local Traffic select Pools > Pool List Select the WAFaaS Pool Under Active Health Monitors select tcp and click >> to move it to Available. This removes the Pool’s Monitor because otherwise it would be marked as down or unavailable. Click Update Note: The Health Monitor needs to be removed because there is no actual ICAP service to monitor. Step #4: ICAP Adapt profiles removed from the Virtual Server From Local Traffic select Virtual Servers > Virtual Server List Locate the WAFaaS ICAP service that ends in “-t-4” virtual server and select it Set the Request Adapt Profile and Response Adapt Profile to None to disable the default ICAP Profiles Click Update Step #5: Application Security Policy enabled and a Policy assigned under Security For the WAFaaS-t-4 Virtual Server click the Security tab Set Application Security Policy to Enabled Select the Security Policy you wish to use. Click Update when done Note: In specific versions of SSL Orchestrator there is one extra configuration item that needs to be modified. This is NOT required in other versions. If this change is made, when performing an upgrade it is not necessarily required to back out this change. Required versions: SSLO version 5.9.15 available on TMOS 14.1.4 SSLO versions 6.0-6.5 available on TMOX 15.0.x Navigate to “Local Traffic ›› Profiles : Other : Service” Select the Service profile named “ssloS_WAFaaS-service” Change the “Type” from “ICAP” to “F5 Module” Conclusion The configuration is now complete. Using the WAFaaS this way is functionally the same as using it by itself. There are no known limitations to this configuration.Get Started with BIG-IP and BIG-IQ Virtual Edition (VE) Trial

Introduction In current times of cyber vulnerabilities, data theft is the ultimate objective with which attackers monetize their presence within a victim network. Once valuable information is identified and collected, the attackers can package sensitive data, bypass perimeter defences, and finalize the breach. Exfiltration (MITRE ATT&CK Tactic TA0010) represents a critical stage of the adversary lifecycle, where the adversaries focus on extracting data from the systems under their control. There are multiple ways to achieve this, either by using encryption and compression to avoid detection or utilizing the command-and-control channel to blend in with normal network traffic. To avoid this data loss, it is important for defenders to understand how data is transferred from any system in the network and the various transmission limits imposed to maintain stealth. This article walks through the most common Exfiltration techniques and how F5 solutions provide strong defense against them. T1020 - Automated Exfiltration To exfiltrate the data, adversaries may use automated processing after gathering the sensitive data during collection. T1020.001 – Traffic Duplication Traffic mirroring is a native feature for some devices for traffic analysis, which can be used by adversaries to automate data exfiltration. T1030 – Data Transfer Size Limits Exfiltration of the data in limited-size packets instead of whole files to avoid network data transfer threshold alerts. T1048 – Exfiltration over Alternative Protocol Stealing of data over a different protocol or channel other than the command-and-control channel created by the adversary. T1048.001 – Exfiltration Over Symmetric Encrypted Non-C2 Protocol Symmetric Encryption uses shared or the same keys/secrets on all the channels, which requires an exchange of the value used to encrypt and decrypt the data. This symmetric encryption leads to the implementation of Symmetric Cryptographic Algorithms, like RC4, AES, baked into the protocols, resulting in multiple layers of encryption. T1048.002 – Exfiltration Over Asymmetric Encrypted Non-C2 Protocol Asymmetric encryption algorithms or public-key cryptography require a pair of cryptographic keys that can encrypt/decrypt data from the corresponding keys on each end of the channel. T1048.003 – Exfiltration Over Unencrypted Non-C2 Protocol Instead of encryption, adversaries may obfuscate the routine channel without encryption within network protocols either by custom or publicly available encoding/compression algorithms (base64, hex-code) and embedding the data. T1041 – Exfiltration Over C2 Channel Adversaries can also steal the data over command-and-control channels and encode the data into normal communications. T1011 – Exfiltration Over Other Network Medium Exfiltration can also occur through a wired Internet connection, for example, a WiFi connection, modem, cellular data connection or Bluetooth. T1011.001 – Exfiltration Over Bluetooth Bluetooth can also be used to exfiltrate the data instead of a command-and-control channel in case the command-and-control channel is a wired Internet connection. T1052 – Exfiltration Over Physical Medium Under circumstances, such as an air-gapped network compromise, exfiltration occurs through a physical medium. Adversaries can exfiltrate data using a physical medium, for example, say a removable drive. Some examples of such media include external hard drives, USB drives, cellular phones, or MP3 players. T1052.001 – Exfiltration Over USB One such circumstance is where the adversary may attempt to exfiltrate data over a USB connected physical device, which can be used as the final exfiltration point or to hop between other disconnected systems. T1567 – Exfiltration Over Web Services Adversaries may use legitimate external Web Service to exfiltrate the data instead of their command-and-control channel. T1567.001 – Exfiltration to Code Repository To exfiltrate the data to a code repository, rather than adversary’s command-and-control channel. These code repositories are accessible via an API over HTTPS. T1567.002 – Exfiltration to Cloud Storage To exfiltrate the data to a cloud storage, rather than their primary command-and-control channel. These cloud storage services allow storage, editing and retrieval of the exfiltrated data. T1567.003 – Exfiltration to Text Storage Sites To exfiltrate the data to a text storage site, rather than their primary command-and-control. These text storage sites, like pastebin[.]com, are used by developers to share code. T1567.004 – Exfiltration Over Webhook Adversaries also exfiltrate the data to a webhook endpoint, which are simple mechanisms for allowing a server to push data over HTTP/S to a client. The creation of webhooks is supported by many public services, such as Discord and Slack, that can be used by other services, like GitHub, Jira, or Trello. T1029 – Scheduled Transfer To exfiltrate the data, the adversaries may schedule data exfiltration only at certain times of the day or at certain intervals, blending the traffic patterns with general activity. T1537 – Transfer Data to Cloud Account Many a times, exfiltration of data can also be through transferring the data through sharing/syncing and creating backups of cloud environment to another cloud account under adversary control on the same service.
