The SecOps Group CAP Exam With Confidence Using Practice Dumps

The Same-Origin Policy (SOP) is a fundamental security mechanism in web browsers that restricts how a document or script loaded from one origin can interact with resources from another origin. An origin is defined by the combination ofprotocol,host, andport. Two pages have the same origin if their protocol (e.g., host (e.g., ), and port (default is 80 for HTTP) match exactly. The given URL is which uses HTTP, host and the default port 80.

Option 1 ("http://www.example.com/dir/other.html"): Matches the protocol (http), host ( ), and port (default 80), so it is in the same origin.

Option 2 ("http://www.example.com:81/dir/other.html"): Differs in port (81 vs. default 80), so it is a different origin.

Option 3 ("http://www.example.com/dir/other.html"): Identical to Option 1, matching protocol, host, and port, so it is in the same origin. However, since it’s a duplicate of Option 1 in the list, it doesn’t add a new page.

Option 4 ("http://en.example.com/dir/other.html"): Differs in host (en.example.com vs. ), so it is a different origin.

Since the question asks which pages are in the same origin, and only Option 1 (and its duplicate Option 3) matches, the correct answer is A ("1 Only"), considering unique pages. The CAP syllabus covers SOP under "Client-Side Security" and "Cross-Origin Resource Sharing (CORS)."References: SecOps Group CAP Documents - "Same-Origin Policy," "Browser Security Models," and "OWASP Client-Side Security" sections.

Let’s evaluate the two statements about NoSQL injection:

Statement A: NoSQL databases (e.g., MongoDB, Cassandra) are designed for scalability and flexibility, often sacrificing strict consistency for performance (e.g., eventual consistency in distributed systems). Unlike traditional SQL databases, they do not enforce rigid relational constraints, which simplifies scaling but does not eliminate the risk of injection attacks. Even without SQL syntax, NoSQL databases are vulnerable to injection if user input is not sanitized (e.g., in MongoDB, injecting $where or $ne operators). This statement is true.

Statement B: NoSQL database queries are typically written in the application’s programming language (e.g., JavaScript for MongoDB), using a custom API (e.g., MongoDB’s query API), or formatted in standards like JSON, XML, or LINQ. For example, a MongoDB query might look like db.collection.find({ "key": input }), where input is a JSON-like structure. This statement accurately describes how NoSQL queries are constructed and is true.

Option A ("A is true, and B is false"): Incorrect, as both statements are true.

Option B ("A is false, and B is true"): Incorrect, as both statements are true.

Option C ("Both A and B are false"): Incorrect, as both statements are true.

Option D ("Both A and B are true"): Correct, as both statements accurately describe NoSQL databases and their vulnerability to injection.

The correct answer is D, aligning with the CAP syllabus under "NoSQL Injection" and "Database Security."References: SecOps Group CAP Documents - "NoSQL Injection Vulnerabilities," "Database Query Security," and "OWASP Top 10 (A03:2021 - Injection)" sections.

When multiple domain names (e.g., and ) resolve to the same IP address (e.g., 1.3.3.7), a web server hosting multiple applications on that IP must determine which application to serve. This is achieved using theHTTP "Host" header, which is part of the HTTP/1.1 protocol. The client (browser) includes the requested domain (e.g., Host: in the request, allowing the server to route the request to the appropriate virtual host or application configured for that domain. This is a standard practice in virtual hosting.

Option A ("The web server inspects the HTTP 'Host' header sent by the client"): Correct, as the Host header enables the server to distinguish between applications on the same IP.

Option B ("The web server inspects the cookies sent by the client"): Incorrect, as cookies are used for session management or personalization, not for identifying the requested application.

Option C ("The web server inspects the client's SSL certificate"): Incorrect, as SSL certificates are used for encryption and authentication, not for application routing (though they may include the domain name for validation).

Option D ("The web server uses a reverse DNS lookup of the client's IP address"): Incorrect, as reverse DNS lookup resolves an IP to a domain, which is irrelevant for the server determining the requested application.

The correct answer is A, aligning with the CAP syllabus under "Web Server Configuration" and "HTTP Protocol Security."References: SecOps Group CAP Documents - "HTTP Headers," "Virtual Hosting," and "OWASP Web Security Testing Guide" sections.
