Threat Injection
A1
Injection flaws, such as SQL, NoSQL, OS, and LDAP injection, occur when untrusted data is sent
to an interpreter as part of a command or query. The attacker’s hostile data can trick the
interpreter into executing unintended commands or accessing data without proper authorization.
Controls: Parameterize queries, Validate all inputs
Threat Broken Authentication
A2
Application functions related to authentication and session management are often implemented
incorrectly, allowing attackers to compromise passwords, keys, or session tokens, or to exploit
other implementation flaws to assume other users’ identities temporarily or permanently.
Controls: Implement identity and authentication controls
Threat Sensitive Data Exposure
A3
Many web applications and APIs do not properly protect sensitive data, such as financial,
healthcare, and PII. Attackers may steal or modify such weakly protected data to conduct credit
card fraud, identity theft, or other crimes. Sensitive data may be compromised without extra
protection, such as encryption at rest or in transit, and requires special precautions when
exchanged with the browser.
Controls: Implement appropriate access controls, Protect data, Encryption protection of sensitive data, Error and exception handling
Threat XML External Entities (XXE)
A4
Many older or poorly configured XML processors evaluate external entity references within XML
documents. External entities can be used to disclose internal files using the file URI handler,
internal file shares, internal port scanning, remote code execution, and denial of service attacks.
Controls: Validate all inputs
Threat Broken Access Control
A5
Restrictions on what authenticated users are allowed to do are often not properly enforced.
Attackers can exploit these flaws to access unauthorized functionality and/or data, such as access
other users’ accounts, view sensitive files, modify other users’ data, change access rights, etc.
Controls: Enforce access controls
Threat Security Misconfiguration
A6
Security misconfiguration is the most commonly seen issue. This is commonly a result of insecure
default configurations, incomplete or ad hoc configurations, open cloud storage, misconfigured
HTTP headers, and verbose error messages containing sensitive information. Not only must all
operating systems, frameworks, libraries, and applications be securely configured, but they must
be patched and upgraded in a timely fashion.
Controls: Web server configuration hardening
Threat Cross Site Scripting (XSS)
A7
XSS flaws occur whenever an application includes untrusted data in a new web page without
proper validation or escaping, or updates an existing web page with user-supplied data using a
browser API that can create HTML or JavaScript. XSS allows attackers to execute scripts in the
victim’s browser which can hijack user sessions, deface web sites, or redirect the user to
malicious sites.
Controls: Encode data
Threat Insecure Deserialization
A8
Insecure deserialization often leads to remote code execution. Even if deserialization flaws do not
result in remote code execution, they can be used to perform attacks, including replay attacks,
injection attacks, and privilege escalation attacks.
Controls: Verify for security early and often
Threat Using Components with Known Vulnerabilities
A9
Components, such as libraries, frameworks, and other software modules, run with the same
privileges as the application. If a vulnerable component is exploited, such an attack can facilitate
serious data loss or server takeover. Applications and APIs using components with known
vulnerabilities may undermine application defenses and enable various attacks and impacts.
Controls: Take advantage of security frameworks and libraries
Threat Insufficient Logging and Monitoring
A10
Insufficient logging and monitoring, coupled with missing or ineffective integration with incident
response, allows attackers to further attack systems, maintain persistence, pivot to more systems,
and tamper, extract, or destroy data. Most breach studies show time to detect a breach is over
200 days, typically detected by external parties rather than internal processes or monitoring.
Controls: Error and exception handling, Implement logging and intrusion detection

Which of the following application settings used to prevent malware incidents will help stop phishing and spyware delivery?
Blocking Web browser pop-up windows
Filtering spam
Filtering website content
In a distributed computing environment, replicated servers could have negative impact on what?
Scalability
Which of the following security principle balances various variables such as cost, benefit, effort, value, time, tools, techniques, gain, loss, risks, and opportunities involved in a successful compromise of security features?
Work factor
Which of the following is similar to security certification and accreditation?
Quality control
What is true when dealing with security principles for securing an application environment?
Data-hiding techniques should be practiced during program testing and software maintenance.
Design for protection mechanisms should be simple and small in size.
Information security functions should be isolated from non-security functions.
Big bang software application testing approach
a testing approach where all the individual components or modules of a software application are tested together, often in a single, comprehensive testing phase. Unlike other testing methods that involve incremental integration and testing of components, Big Bang Testing focuses on evaluating the entire system’s functionality as a whole.
This approach is typically employed after the individual units or modules have undergone unit testing. Once these units are ready for integration, they are combined in a “big bang,” and testing is carried out on the complete system.
Finite State Machines are used in what phase?
Initiation
