10.
Why Security DevOps?
» Keep up with rollout pace in agile projects
» Automate certain checks as best as possible within
the build-chain
» Early feedback to Devs
» Solution that scales across the company
» Does not remove the manual pentest requirement!
» Aims to free pentesters’ time to hunt more
high-hanging bugs

11.
Different levels of "Security DevOps" integration…
» Security DevOps Maturity Model (SDOMM)
» Can be seen as some automation tips within
OpenSAMM’s security practices
» Verification: Security Testing
» Verification: Code Reviews
» Allows to define a RoadMap for projects

Four different axes

15.
Let’s explore these axes …
» … by showing how to implement this
with OpenSource solutions used in the
Security & Development domains.

16.
Axis of "Dynamic Depth"
How deep are dynamic scans executed
within a Security DevOps CI chain?
i.e. "where" are dynamic
security tests applied?

17.
Axis "Dynamic Depth": Level 1
Scanning of public attack surface (pre-auth):
» Spidering of UI layer
» No requirement to authenticate scanner with target
» Easy integration of scanner(s) in nightly build as
post-step
» "Throw tool at it (in CI-chain) and see what it
generates…"

18.
Zed Attack Proxy (ZAP)
"OWASP ZAP" features:
»passive scanning (Proxy / Spider)
»active scanning (Proxy / Spider)
»manual payload delivery (Intercepting Proxy)
»Spider (classic & AJAX)
»Fuzzing
»Plugins
»…

19.
Request/Response History (Proxy)

20.
Active Scanning…

21.
OWASP ZAP

22.
ZAP in SecDevOps?
"OWASP ZAP" features
relevant for Security DevOps integration:
»Headless operation mode / daemon
»REST-API
»Highly scriptable
»CLI

23.

26.
ZAP + Jenkins = SecDevOps?
"OWASP ZAP" (spider & scanner) + Jenkins plugin “ZAProxy"
» Allows us to "Spider & Scan" as step in build job
via Jenkins plugin "ZAProxy"
» Point plugin config to URL of integration system to test
» Plugin saves HTML-report in project’s job for inspection
» Best as separate Jenkins job to run during nightly build
(duration)
– Use different ZAP proxy ports for different builds to allow
parallel execution of different project build jobs

27.
Jenkins Plugin "ZAProxy": ZAP Startup

28.
Jenkins Plugin "ZAProxy": ZAP Scan

29.
Arachni in SecDevOps?
"Arachni Scanner" features relevant for Security
DevOps integration:
» Passive & active scanning (Proxy / Spider)
» Uses internally a headless browser-cluster
(for apps with lots of JS)
» Automation?
– direct CLI + RPC-API (with CLI)
» Web-UI (helpful when permanently
running as server)

30.
Arachni + Jenkins = SecDevOps?
"Arachni Scanner" + Jenkins CLI step in build
» Start in build job as CLI step and point to URL
of system under test
» Generate HTML report and place into
workspace for inspection
» Better execute within nightly build job
(due to duration)
» Alternatively:
Start remote (also via CLI) to run async

31.

33.
BDD-Security in SecDevOps?
BDD-based framework for functional and technical security tests:
» Technical security tests
(i.e. check against XSS, SQL-Injection, XXE, etc.)
– uses ZAP as scanning engine (among others)
» Functional security tests
(i.e. check UserA can’t access data from UserB)
» Tightly integrates with Selenium based app navigation workflows
» Uses JBehave for G/W/T stories & reporting
» Can run within CI (Jenkins, etc.) due to JBehave
or as JUnit tests

34.
BDD-Security Story: Scan for XSS

35.
HTML report of BDD-Security
Bildquelle: BDD-Security

36.
Gauntlt in SecDevOps?
BDD-based framework for executing many security tools/
scanners:
» Integrates scanners like Arachni, ZAP, sqlmap, etc.
– Easy to integrate "your custom scanner tool" with
Gauntlt as well
» Allows to call different scan polices via BDD-stories (G/W/T)
» Integration with Jenkins (or other build servers) by either
– Linking Gauntlt’s HTML report to build, or by
– modifying how Gauntlt calls Cucumber to produce
JUnit output

37.
Other dynamic scanners exist also…
Some have different focus
» Nikto
» w3af
» IronWASP
» Nessus
» Mittn (BDD-based)
» Gauntlt (BDD-based)
» Minion (integration framework)
» OWTF (integration framework)
» good commercial ones
» etc.

38.
Axis "Dynamic Depth": Level 2
Scanning of authenticated parts (= "post-auth")
via UI layer
» Properly maintaining sessions
» Logout-detection & automatic re-login
» Different users / roles
» Spider & scan post-auth
Handling of hardening measures of application under test
» CSRF-Tokens, etc.

39.
Guide ZAP into Post-Auth in CI
Use ZAP manually (1x) to configure "Context": Auth, RegExps for
Logged-In/Out Indicators, Users etc.
– save as "ZAP Session-File" (could be in code repo)
– use that "Session-File" from code repo as starting point of scan
(loaded as ZAP session during build job).
Note: Current version of ZAP has a bugfix pending for loading creds from session file
One can set these auth values and/or additional data via ZAP’s REST-API
during each build before scan starts (from Jenkins/Maven/…)
– use that to define current active session etc. during spider & scan
Also Scripts in JavaScript or Zest can be registered in ZAP context
to programmatically give authentication to ZAP

40.
Login config example within ZAP

41.
ZAProxy Jenkins Plugin: ZAP session use

42.
Guide Arachni into Post-Auth
Give authentication infos to Arachni
(Auth, Logged-In Indicators, Users)
» Use Arachni "autologin" plugin to specify via command line
– Login URL, formfield names, credentials, logged-in
indicator, excludes
» Alternatively write custom ruby script for "login_script" plugin
– Individual custom login logic possible
– Logged-In indicators (RegExp) to know when to re-login

43.
./arachni
--plugin=autologin:
url=https://example.com/login.action,
parameters='j_username=foo&j_password=bar',
check='Logout'
--scope-exclude-pattern=logout.action
https://example.com/
Login config example
within Arachni (used in CI)
Or individual ruby script if more custom login logic required…
Eventually also --session-check-url & --session-check-pattern
>> Easier to achieve Post-Auth Scan with Arachni (compared to others)
>> Can also be ordered via CLI remote/async during build (nightly) or scheduled (WebUI)

44.
Arachni Web-UI:
Scan scheduling
Bildquelle: Arachni Scanner

45.
Guide BDD-Security into Post-Auth
Use Selenium to navigate through the login process
» Based on excellent integration of BDD-Security with Selenium
» Separate app navigation code (Selenium) from Security
testing code
» Use Selenium class (that handles login) within BDD stories
» Perform further spidering & active scanning (through ZAP)
post-auth

46.
public class ShopApplicationScanHelper
extends WebApplication implements ILogin {
// ... integrates with BDD-Security via parent class & interface ...
}

47.
public class ShopApplicationScanHelper
extends WebApplication implements ILogin {
@Override
public void openLoginPage() {
}
@Override
public void login(Credentials credentials) {
}
@Override
public boolean isLoggedIn(String role) {
}

48.
public class ShopApplicationScanHelper
extends WebApplication implements ILogin {
@Override
public void openLoginPage() {
driver.get(Config.getInstance().getBaseUrl() + "customer/login");
verifyTextPresent("Login");
}
@Override
public void login(Credentials credentials) {
UserPassCredentials creds = new UserPassCredentials(credentials);
driver.findElement(By.id("username")).clear();
driver.findElement(By.id("username")).sendKeys(creds.getUsername());
driver.findElement(By.id("password")).clear();
driver.findElement(By.id("password")).sendKeys(creds.getPassword());
driver.findElement(By.name("_action_login")).click();
}
@Override
public boolean isLoggedIn(String role) {
if (driver.getPageSource().contains("My Account")) {
return true;
} else {
return false;
}

49.
What about CSRF-Tokens?
ZAP can handle CSRF-Tokens
» Can be individualised via configuration
BDD-Security uses (among others) ZAP for scanning
Arachni can also handle CSRF-Tokens

50.
Apply targeted delta scanning:
• Developer teams maintain "scope delta files" in SCM
• like "what parts of the application have changed during this sprint"
(= URL patterns)
• could’ve been recorded in proxy-based tools (like ZAP) by Devs
• DAST Scanner uses it to scan only this during onCommit or nightly CI run
• Feed this delta information as argument to scope definitions
Arachni: --scope-include-pattern / --scope-exclude-pattern
ZAP: Include/Excludes in Context (via Session-File or REST-API)
BDD-Security: maintain as "table file" of RegExps as scope
If scanning takes too long? (1/2)

51.
If scanning takes too long? (2/2)
Train spiders about the structure of application to reduce scan
redundancy and avoid scanning static resources
• ZAP: use RegExp "Exclude from scanner" rules to prevent
redundant scans in data-driven applications (i.e. scan only one
instance of it)
• Arachni: --scope-redundant-path-pattern / --scope-auto-redundant
as well as --scope-exclude-pattern="logout.|.js|.css|.jpg|.png"
Don’t forget to scan complete application at least on nightly or weekly run
• Only apply full scan, if simple smoke-tests are green

52.
Axis "Dynamic Depth": Level 3
Separate scanning of different application layers / backends
• Scan internal WebServices (e.g. SOAP / REST) = directly scan backends
• Detect and scan parameter positions within XML, JSON, …
• Scan from "within" the different application’s layers
• IAST with distributed agents & instrumentation aims into that direction
• At least one simple step in that direction:
• Use the proxy also between your backend service calls

53.
Backend scans with ZAP
How to achieve this with ZAP?
• ZAP operates as proxy server: place it between backend calls
• ZAP can inject payloads in observed XML tags/attributes & JSON fields
• Capture service call traffic in integration test during CI while either
A. frontend UI tests execute service backend calls indirectly, or
B. executing service tests that directly access the service endpoint
• Automatically scan as new requests are seen: "ATTACK Mode"
Also keep an eye on an alpha-level SOAP-Scanner ZAP addon

54.
Backend scans with Arachni
How to achieve this with Arachni?
• Arachni can also operate as proxy: place it between backend
calls
• Use passive proxy plugin to "train" Arachni of the XML / JSON
requests
• New addition in v1.1 to extract XML / JSON input vectors
from it
• Use that collected input vector data to feed the active scan for
the observed requests

55.
Axis "Dynamic Depth": Level 4
Targeted scanning of individual forms / wizards (UI)
and service layers
» More individualised workflow coverage
(not just simple spidering)
» Business-logic compliant usage patterns & inputs
– "fill shopping cart followed by checkout process"
– "access backend WebServices in special order to test
workflow", etc.
» Custom coded security tests tailored to the application

56.
ZAP with special workflows (1/3)
Many ways exist…
The simplest one could be:
Re-use existing UI tests (Selenium, …)
» Proxy this traffic through ZAP in
“ATTACK-Mode" (in security test phase of build)
» Optionally use ZAP Attack-Policies to specify/limit
certain attack types

57.
ZAP with special workflows (2/3)
A more customised handling of individual workflows can
be achieved:
Re-use & enhance existing "UI test code" at the desired
workflow steps with calls to ZAP’s (REST)-API ordering attacks
» Basically it’s like Unit-Test code that uses Selenium along
with ZAP-Calls at the proper positions in application workflow
» Type of "ordered attacks" can again be defined via policies
» Start ZAP as Daemon from Jenkins via plugin

58.

(optionally define parameter excludes via API
or ZAP "input vector scripts" if custom input format) */
}
@Test
public void testBillingAddressStep() {
}
}

62.
See https://github.com/continuumsecurity/zap-webdriver
for a great working example of Selenium ZAP integration
public class ShopApplicationTest { // = regular JUnit unit test
@Before
public void setup() {
// 1. start new proxy session in running ZAP (via REST-API call)
// 2. create Selenium driver (proxying through running ZAP)
}
@Test
public void testShippingAddressStep() {
// 1. use Selenium to fill shopping cart
// 2. use Selenium to proceed to checkout
// 3. use Selenium to provide reasonable shipping address data
// 4. set attack policy (types & strength) in running ZAP (API)
/* 5. call ZAP (API) to actively scan the last seen URL
(optionally define parameter excludes via API
or ZAP "input vector scripts" if custom input format) */
}
@Test
public void testBillingAddressStep() {
// same idea as above ... just continue with the pattern
}
}

63.
ZAP with special workflows (3/3)
Alternatively "train" ZAP about the workflow by
recording Zest scripts
»Keep an eye on "Sequence Scanning"
alpha-level ZAP AddOn
–Still alpha-level (as of June 2015), but
interesting approach

64.
BDD with special workflows
Use Selenium to further drive BDD-Security initiated checks:
» Selenium-based test code navigates application workflows
» This code is integrated with BDD (via Java interfaces),
so that:
– BDD-Security stories can use that code to navigate
and generate traffic
– This generated traffic will be scanned by ZAP via BDD

65.
public class ShopApplicationScanHelper
extends WebApplication implements ILogin {
// ... already covered login handling code
// in BDD-Security example ...
public boolean fillShoppingCartAndCheckout() {
// custom Selenium (recorded) code
// to drive certain use cases (like shopping) ...
}
}

66.
Use this navigation method inside BDD-Security scenario:
...
Given a new scanning session
And the page flow described in the method:
fillShoppingCartAndCheckout is run through the proxy
...

67.
If no Selenium test code exists?
Simply give developer teams access to ZAP to (at least)
pre-seed the scanner:
» Developer teams use browser to navigate app workflows while proxying
– Thereby seed the ZAP session(s) with navigation nodes/workflows
– Save the ZAP session(s) and check-in into SCM (Git, SVN, …)
» Point the Jenkins ZAP plugin to the saved ZAP session(s) as starting
point
» Devs can add to this list of URLs for ZAP with each new UI
BTW: ZAP is also available as Docker image…

68.
Sometimes it’s useful to have programmed unit-tests directly
calling a business API
• Test directly at the API-level (i.e. Java code level)
• Utilise fuzzing values from popular sources like "fuzzdb"
and/or generate on-the-fly with fuzzer "radamsa"
• Check the API method’s response
(like regular unit test, but seeking for signs
of successful attack tests)
Security-UnitTests for APIs (1/2)

69.
Security-UnitTests for APIs (2/2)
Leverage the benefit of direct API-level testing
(i.e. testing "from within")
• Place "probes" into the application to watch out for successful
attack tests
• Check some OWASP AppSensor detection points for
potential attack triggers (RASP-like)
• Error logs are good candidates to check also
• Mock objects (Mockito, etc.) or weave aspects (AOP)
collecting data (i.e. method calls and arguments, etc.)

70.
Axis of "Static Depth"
How deep is static code analysis performed
within a Security DevOps CI chain?
i.e. "where" are static
security tests applied?

71.
Axis "Static Depth": Level 1
Assurance that no third-party code with known
vulnerabilities is used
» Check application’s server-side dependencies
– For Java applications: JAR files, etc.
» Check application’s client-side dependencies
– JavaScript frameworks, etc.
Useful even for projects not currently under development
» New vulnerabilities could become public:
Build regularly to check

72.
Java libs: OWASP Dependency-Check
Scans all dependencies (even transitive ones)
against CVE list
» Available as Maven plugin and Ant task
» CLI version also available
» Jenkins plugin for nice reporting
(and build breaking thresholds)
» Not false-positive free
– regularly needs some time to triage findings

73.
Reporting in Jenkins

74.
Findings (CVE-Details)

75.
JavaScript libs: retire.js
Scans application’s JavaScript files against list
of known vulnerable ones
» Available also as Maven Plugin …
» … and as CLI
(point it to your folder containing .js files)

76.
Axis "Static Depth": Level 2
Scan important parts of source code
for vulnerability patterns
» At least important parts of applications’ codebases are
scanned
– like in-house reused code & custom developed
frameworks
– for big multi-project Maven projects:
at least frontend and backend projects
– or code of changed modules within a sprint

77.
Java: FindSecurityBugs
Plugin for FindBugs with enhanced checks for security issues
in Java code
» Runs within FindBugs, so that it can execute in Maven and/or Sonar
» Generates XML-file with potential findings
» Jenkins plugin for representing results
(also possible to display in Sonar)
– Integrates with Jenkins "Static Code Analysis" as part of FindBugs
– Delta reporting of new (and fixed) findings & trends

78.
FindBugs in Jenkins: Trends, etc.

79.
in Sonar: Vulnerability & Code-Pointer

80.
JavaScript: ScanJS
Scans JavaScript code for vulnerabilities
» Most importantly DOM-based XSS (Cross-Site Scripting)
» Flags also "Usage of sensitive API" issues
» Executable as CLI from within Jenkins build steps
» Optional Web-UI (running as local server)

81.
ScanJS Findings as HTML: DOM-XSS

82.
Ruby on Rails apps: Brakeman
Scans RoR code for vulnerabilities
» CLI based
» Nicely integrates with Jenkins
– Rendering scan results and trend analysis
» Allows to compare scan results (delta detection)
– "What has been fixed and what was newly introduced?"

83.
Other static scanners exist also…
Some have different focus
» PrimeJS (like ScanJS for JavaScript DOM-XSS etc.)
» PMD (for Java code regarding API safety issues)
» good commercial ones
» etc.

84.
Axis "Static Depth": Level 3
Scan the complete applications’ source code
for vulnerability patterns
» Just like "Level 2", but now for the complete codebase
(no excludes)
– i.e. all projects of a multi-project Maven project
– best via parent or corporate pom.xml
For FindSecurityBugs this means:
» pre-compile even all JSPs (if you have any)
to scan them

85.
Axis "Static Depth": Level 4
Scan code of (important) third-party dependencies
used in application
» If the component is open-source:
– include it in regular scanning activities
» If the component is closed-source:
– consider using code scanners that operate on binaries
• FindBugs (hence its FindSecurityBugs plugin) can also
scan Java binaries, since it operates on Bytecode

86.
Axis of "Intensity"
How intense are the majority of the
executed attacks within a Security
DevOps CI chain?
i.e. "what" is being checked for?

87.
Axis "Intensity": Level 1
Dynamic checks: Only passive scanning
» Simply proxy testcase generated traffic through passive operating
scanners
» Quick-win for using existing testcase code (i.e. Service- or UI-tests)
» Can execute within existing tests that execute on every commit
– No requirement for a separate nightly CI job
(i.e. doesn’t slow down build)
Static checks: Just scan the code along with other code metrics
» Use the default rules of the scanners and integrate them into CI

88.
Axis "Intensity": Level 2
Use lightweight active scanning options for dynamic checks
» ZAP: active scanning of observed URLs (proxied or spidered)
– perform an "active scan": For Jenkins ZAProxy Plugin
provide a ZAP policy with desired active scan intensity
(or via ZAP’s REST-API during build for other setups)
» Arachni: enable "active scan" during spidering
» BDD-Security stories can call ZAP with policy files defining
attack strength
Better to execute in separate (nightly) build job due it’s to duration
Think of resetting databases (+ more environment) prior or after
test execution

89.
Axis "Intensity": Level 3
Use heavyweight scanning options on important parts of application
Dynamic checks: create "riskier" custom attack profiles
ZAP:
– set "Threshold" to "Low" / "Strength" to "High" (or selectively "Insane")
– enable more scanning rules via Policy Files (could be maintained &
used via SCM)
– use ZAP’s "Advanced SQLInjection Scanner" extension (or directly
call sqlmap)
Arachni:
– Enable the more aggressive "audit flags" like --audit-forms, …
Static checks: FindSecurityBugs: set "Threshold"
to "Low" / "Effort" to "Max"

90.
Axis "Intensity": Level 4
Use customised rule sets for dynamic checks
ZAP
(which is very extensible via custom scripts, recored and
customised Zest, or plugins):
» Custom coded scan scripts as active & passive scan rules for
company-individual checks
» Security regression tests (in Zest) against previous found
vulns (also logic flaws)
» Custom input vector scripts: e.g. define certain injection
points in custom encoded params
» Proxy scripts: for example for generic request/response
modifications

91.
Scripting possibilities in ZAP

92.
… and for static code scans?
Use customised rule sets for static checks
FindSecurityBugs
» Custom coded rule files (in Java) to check for wrong usages of
server-side inhouse frameworks (or alike)
ScanJS
» Custom rule files (in JSON) to check for wrong usages of
client-side inhouse frameworks (or alike)

93.
Axis of "Consolidation"
How complete is the process of handling
findings within a Security DevOps CI chain?
i.e. "how" are the results used?

94.
Axis "Consolidation": Level 1
Generate human-readable (HTML) reports from tools and link
them in Jenkins
» All relevant mentioned static and dynamic scanners generate
HTML reports
» Collect and publish them in Jenkins build: via Jenkins
"HTML Publisher Plugin"

95.
Jenkins "HTML Publisher Plugin":
Configuration of HTML reports to link

96.
Jenkins "HTML
Publisher Plugin":
Result in build

97.
HTML report of ZAP scan

98.
Axis "Consolidation": Level 1 (cont.)
Use simple criteria to "break the build" on heavy findings
(ok, at least "unstable")
» Most scanners have capabilities to automatically flag the build
» Dependency-Check (Severity Threshold),
» BDD-Security (with the JBehave-stories),
» FindSecurityBugs (via Sonar when rated as blocker),
» Arachni (via Gauntlt execution with BDD-like stories),
» etc.
» For others: at least do a simple log parse from
Jenkins "Log Parser Plugin" to flag the build as
unstable and/or broken

99.
OWASP Dependency-Check:
Thresholds to break build

100.
FindSecurityBugs:
IDE support & Collaboration
FindBugs (with FindSecurityBugs) has good Jenkins & IDE integration
Additionally consider placing the FindBugs generated XML report file
within Jenkins
» Developers can load the XML report file into FindBugs IDE plugins
(Eclipse, IntelliJ, NetBeans, …)
» Developers & Security Analysts can collaborate on bugs
via the IDE plugins
– See https://code.google.com/p/findbugs/wiki/FindBugsCloudTutorial
for more details
• Consider installing it as your private "FindBugs"-Server
on-premise to keep results only on your servers…

101.
FindSecurityBugs Eclipse Perspective
with Collaboration View + Remediation

102.
Axis "Consolidation": Level 2
Custom logic to make build unstable and/or broken
depending on
» Type of vulnerability (CWE or WASC or …)
» Severity ranking (high risk)
» Confidence level (firm vs. tentative)
Provide useful remediation info to developers
Respect suppression mechanisms to rule out
false positives

103.
Flagging builds from reports
How (from within a CI job)?
» Most scanners also emit XML reports that can be parsed
– Often a simple XPath count is just fine
» Alternatively fetch the results by accessing the scanner’s API
» Be sure to only break build with findings of
high severity and high confidence !!!
– Less is more (when it comes to automation)…
» When new check introduce many findings:
Baseline-Approach: Only break on new findings

104.
Providing useful info to Devs
Lookup CWE-ID (provided by most scanners) in vulndb:
» https://github.com/vulndb/data
(currently 65+ vulns described)
» Useful if the messages from scanners are too generic
or don’t help much
» Maps vulnerability to useful remediation messages
» Possibility to extend that repository locally with
company-individual texts (mapping to the technology
stack) —> that’s where it pays off…

105.
Suppression of false positives
Custom finding list (from XML reports):
filter out according to list from code repo
BDD-Security: Use false positive tables in story files
(i.e. text files checked in SCM)
FindSecurityBugs: Use exclusion lists in config (XML filter files)
& annotation @SuppressWarnings on false positive code lines
Dependency-Check: XML file of suppressions
(checked-in along with the project)
retire.js: "ignore file" parameters on CLI
(cloud be loaded in CI from code repo)

106.
Axis "Consolidation": Level 3
Consolidation goals:
» Consolidate & de-duplicate findings from different
scanner reports (with better false positive handling)
» Push consolidated findings into established bug-tracker
(known to devs)
» Delta analysis & trends over consolidated data sets

107.
ThreadFix as result consolidator
Use a local ThreadFix server, which imports native scanner outputs
• does the heavy lifting of consolidation & de-duplication
