Adversaries may attempt to take advantage of a weakness in an Internet-facing computer or program using software, data, or commands in order to cause unintended or unanticipated behavior. The weakness in the system can be a bug, a glitch, or a design vulnerability. These applications are often websites, but can include databases (like SQL)(Citation: NVD CVE-2016-6662), standard services (like SMB(Citation: CIS Multiple SMB Vulnerabilities) or SSH), network device administration and management protocols (like SNMP and Smart Install(Citation: US-CERT TA18-106A Network Infrastructure Devices 2018)(Citation: Cisco Blog Legacy Device Attacks)), and any other applications with Internet accessible open sockets, such as web servers and related services.(Citation: NVD CVE-2014-7169) Depending on the flaw being exploited this may include Exploitation for Defense Evasion.
If an application is hosted on cloud-based infrastructure and/or is containerized, then exploiting it may lead to compromise of the underlying instance or container. This can allow an adversary a path to access the cloud or container APIs, exploit container host access via Escape to Host, or take advantage of weak identity and access management policies.
For websites and databases, the OWASP top 10 and CWE top 25 highlight the most common web-based vulnerabilities.(Citation: OWASP Top 10)(Citation: CWE top 25)

| identity_aware_proxy | Identity Aware Proxy | technique_scores | T1190 | Exploit Public-Facing Application |
Comments
When an application or resource is protected by IAP, it can only be accessed through the proxy by principals, also known as users, who have the correct Identity and Access Management (IAM) role. IAP secures authentication and authorization of all requests to App Engine, Cloud Load Balancing (HTTPS), or internal HTTP load balancing.
With adversaries that may try to attempt malicious activity via applications, the application Firewalls may be used to limit exposure of applications to prevent exploit traffic from reaching the application.

Comments
Once this control is deployed, it can detect known vulnerabilities in various Linux OS packages. This information can be used to patch, isolate, or remove vulnerable software and machines. This control does not directly protect against exploitation and is not effective against zero day attacks, vulnerabilities with no available patch, and other end-of-life packages.

Comments
Often used by adversaries to take advantage of software weaknesses in web applications, Palo Alto Network's vulnerability signatures are able to detect SQL-injection attacks that attempt to read or modify a system database using common web hacking techniques (e.g., OWASP top 10).
Although there are ways an attacker could leverage web application weaknesses to affect the sensitive data and databases, this technique was scored as significant based on Palo Alto Network's advanced threat detection technology which constantly updates to detect against the latest known variations of these attacks.

Google Cloud Armor security policies protect your application by providing Layer 7 filtering and by scrubbing incoming requests for common web attacks or other Layer 7 attributes. Google Cloud Armor detects malicious requests and drops them at the edge of Google's infrastructure.

Comments
Chronicle triggers an alert based on suspicious behavior, such as exploitation attempts against web servers and/or applications (e.g., F5 BIG-IP CVE 2020-5902).
This technique was scored as minimal based on low or uncertain detection coverage factor.

Comments
Using Web Security Scanner, SCC is able to detect and provide guidance for web application security risks (e.g., Cross-Site Scripting, SQL injection, Server Side Request Forgery, Insecure Deserialization). Adversaries may exploit these web app weaknesses in a cloud-based environment to compromise the underlying instance or container. This technique was graded as significant due to the high detect coverage against varying forms of this attack.

Comments
VM Manager can apply on-demand and scheduled patches via automated patch deployment. This can remediate OS and software vulnerabilities that could otherwise be exploited. Since VM Manager doesn't directly prevent exploitation of active vulnerabilities (including zero day vulnerabilities) this control has resulted in a score of Partial.
