In a world with constantly changing and increasingly complex attacks on web applications, security practices are evolving to stay ahead of the threats. Dave Shackleford, IANS Research application security faculty member, and Bala Venkat, Cenzic CMO, explain how government agencies can benefit from continuous security monitoring.
These are the slides from "Continuous Monitoring for Web App Security," a Cenzic and IANS webinar that originally aired on 10 September 2013. The video recording is available at info.cenzic.com (free, registration required).
In the webinar, Dave and Bala discuss the types of attacks currently seen in the wild, what attackers are focused on, and how they are compromising web applications, systems and data. We'll explore the most pressing compliance and regulatory challenges for government agencies and commercial businesses. Finally, we'll show how continuous monitoring tactics and tools can improve your security posture.

Risk Management &
Continuous Monitoring
! Continuous Monitoring only follows sound
risk management practices & control
selection as outlined in NIST 800-53 and
800-37
! Not replacing traditional risk assessment
and security authorization
! The final step in the RMF (a key component
in back-end security, as defined by NIST)

Lots of Changes to Federal IT
Security and Compliance
! Before: Go through C&A, get an ATO
! Acronyms: Certification & Accreditation (C&A),
Authority to Operate (ATO)
! FISMA specifies:
! Periodic Risk Assessments
! Periodic Testing & Evaluation
! Annual Security Review
! Annual Reporting

Conducting a thorough point-in-time assessment of the
security controls in an organizational information system is a
necessary but not sufficient condition to demonstrate security
due diligence…The ultimate objective of the continuous
monitoring program is to determine if the security controls in
an information system continue to be effective over time in light
of the inevitable changes that occur in the system as well as the
environment in which the system operates.

In other words…
! Moving from:
! To:
Those security controls that are volatile or critical to
protecting the information system are assessed at
least annually. All other controls are assessed at
least once during the information system s three-
year accreditation cycle.
A continuous monitoring program allows an organization to
maintain the security authorization of an information system
over time in a highly dynamic environment of operation with
changing threats, technologies and missions/business
processes. Continuous monitoring of security controls
using automated support tools facilitates near real-time risk
management and promotes organizational situational
awareness with regard to the security state of the
information system.

More on SCAP
! Multiple standards for assessing configuration
and vulnerabilities, and reporting them
! CVE (Vulns)
! CVSS (Vuln scoring or rating)
! CCE and CPE (Enumeration)
! XCCDF and OVAL (Configs and Reporting)
! Intended to provide standards for scanners,
local system assessment, and reporting
! Cross-tool correlation and monitoring/alerting is a
critical function, too

Tying Web assessment to
event monitoring
! Specific Web app scanning details to correlate:
! Vulnerability details
! Open ports and running/listening services
! Risk ratings for vulnerabilities
! System/application details
! Correlation Examples:
! System/application details: Correlate with current
inventory
! Open ports: Correlate with configuration details to
determine whether unauthorized changes were made or
services are vulnerable
! Vulnerability details: Correlate with configuration
details to determine whether unauthorized changes
were made or services are vulnerable

• System and application inventories can be
leveraged for a number of reasons
– Determine whether systems or applications are
approved
– Enforce license compliance
– Determine whether systems or applications need
upgrades

Continuous Monitoring + CAG:
Assets/Inventory
! Specific elements we want to learn with scanning:
! System and asset names
! Platform and application details (what is installed,
versions, patches applied, etc.)
! Asset IP/MAC addresses
! License status and details (maybe)

Continuous Monitoring + CAG:
Assets/Inventory
! Correlation Examples:
! System/application details: Correlate with
configuration details and remediation plans to ensure
consistency
! Asset IP/MAC addresses: Ensure system addresses
have not changed
! License status/details: Correlate with system
configuration to ensure applications are authorized and
licensed

So…How s all this work?
! A huge amount of application and
vulnerability detail needs to be collected in
today s Federal IT environments
! All public-facing and critical apps need to be monitored
continually
! These data sets should be aggregated, correlated and
used to create meaningful alerts
! Assessment and reporting should follow
consistent formatting
! SCAP is the emerging standard
