Subscribe to Cisco Security Notifications, https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-asa-webvpn-LOeKsNmO, Release Notes for the Cisco ASA Series, 9.17(x). Based on a presentation at LocoMocoSec, the following two policies can be used to apply a strict policy: When default-src or script-src* directives are active, CSP by default disables any JavaScript code placed inline in the HTML source, such as this: The inline code can be moved to a separate JavaScript file and the code in the page becomes: With app.js containing the var foo = "314" code. Security Security at every step and in every solution. Security is a system property rooted in hardware, with every component from software to silicon playing a role in helping secure data and maintain device integrity. As of 2015[update] draft of Level 3 is being developed with the new features being quickly adopted by the web browsers. Type of action. The header name Content-Security-Policy should go inside the http-equiv attribute of the meta tag. You could try the following to check the box (warning this does nothing): You can try a CSP Generator if you want an easy way to play with it: Although CSP doesn't prevent web applications from containing vulnerabilities, it can make those vulnerabilities significantly more difficult for an attacker to exploit. The inline code restriction also applies to inline event handlers, so that the following construct will be blocked under CSP: This should be replaced by addEventListener calls: Copyright 2021 - CheatSheets Series Team - This work is licensed under a, CSP is not a substitute for secure development, 2. I prefer women who cook good food, who speak three languages, and who go mountain hiking - what if it is a woman who only has one of the attributes? We have a suite of technologies to build and execute on a defense in-depth strategy, with solutions spanning threat detection, data/content protection, memory protection and more. With a single interface to master, your team spends less time in training. There are no inlines or evals for scripts and style resources. Filter by content type or product. If the Content-Security-Policy header is present in the server response, a compliant client enforces the declarative allowlist policy. A vulnerability in the packaging of Cisco Adaptive Security Device Manager (ASDM) images and the validation of those images by Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker with administrative privileges to upload an ASDM image that contains malicious code to a device that is running Cisco ASA Software. This list allows for granular control of the source of scripts, images, files, etc. Reporting directives deliver violations of prevented behaviors to specified locations. security and efficacy of CETs, such as the responsible development and deployment of cyber-secure and resilient technologies. how should we set ours? The element needs to explicitly declare its type. You may have to add unsafe-eval in some cases as well for this to work. The standard, originally named Content Restrictions, was proposed by Robert Hansen in 2004,[4] first implemented in Firefox 4 and quickly picked up by other browsers. Dynamic content security. Date. Asking for help, clarification, or responding to other answers. CISCO RESERVES THE RIGHT TO CHANGE OR UPDATE THIS DOCUMENT AT ANY TIME. We basically identified what we use and don't use. A vulnerability in the Cisco Cluster Management Protocol (CMP) processing code in Cisco IOS and Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause a reload of an affected device or remotely execute code with elevated privileges. The CSP policy only applies to content found after the meta tag is processed, so you should keep it towards the top of your document, or at least before any dynamically generated content. How does Content Security Policy (CSP) work? Whenever a browser supports report-to, it will ignore report-uri. If the developer is migrating from HTTP to HTTPS, the following directive will ensure that all requests will be sent over HTTPS with no fallback to HTTP: A strict policy's role is to protect against classical stored, reflected, and some of the DOM XSS attacks and should be the optimal goal of any team trying to implement CSP. Version 1 of the standard was published in 2012 as W3C candidate recommendation[5] and quickly with further versions (Level 2) published in 2014. A lack of a CSP policy should not be considered a vulnerability. Providing every legitimate workload with a trusted execution environment for hardware-isolated protection of data in use, scaled to fit workloads of varying sizes. Fetch directives tell the browser the locations to trust and load resources from. Should we burninate the [variations] tag? The Cluster Management Protocol utilizes Telnet internally as a signaling and command protocol between When a user visits a page served over HTTPS, their connection with the web server is encrypted with TLS and is therefore safeguarded from most sniffers and man-in-the-middle attacks. A Content Protection Policy (CSP) is a security standard that provides an additional layer of protection from cross-site scripting (XSS), clickjacking, and other code injection attacks.It is a defensive measure against any attacks that rely on executing malicious content in a trusted web context, or other attempts to circumvent We have a suite of technologies to build and execute on a defense in-depth strategy, with solutions spanning threat detection, data/content protection, memory protection and more. // Intel is committed to respecting human rights and avoiding complicity in human rights abuses. @ebuntu What makes you believe this is not a vulnerability? This includes images (img // Performance varies by use, configuration and other factors. The meta support is handy when you can't set a HTTP response header, but in most cases using a HTTP response header is a stronger approach. [31], The W3C Web Application Security Working Group considers such script to be part of the Trusted Computing Base implemented by the browser; however, it has been argued to the working group by a representative of Cox Communications that this exemption is a potential security hole that could be exploited by malicious or compromised add-ons or extensions. A sites security certificate guarantees the connection is safe and secure. CSP reports are standard JSON structures and can be captured either by application's own API[27] or public CSP report receivers. Why is SQL Server setup recommending MAXDOP 8 here? We have a suite of technologies to build and execute on a defense in-depth strategy, with solutions spanning threat detection, data/content protection, memory protection and more. One thing to clear up here is that policy doesn't "have dependencies" on the google links.

When setting up dynamic content, such as mod_php, mod_perl or mod_python, many security considerations get out of the scope of httpd itself, and you need to consult documentation from those modules. How can we build a space probe's computer to survive centuries of interstellar travel? Now that were familiar with the common directives and source values for a Content Security Policy, lets go over some examples of CSPs that address a few common website security scenarios. [28] This behaviour is intended and cannot be fixed, as the browser (client) is sending the reports. One example goal of a policy is a stricter execution mode for JavaScript in order to prevent certain cross-site scripting attacks. I'm storing as much JavaScript as possible in files instead of inline, but by default, WebForms injects a lot of inline scriptsfor things as simple as form submission and basic AJAX calls.
