NEW QUESTION # 31
A recent penetration test discovered that several employees were enticed to assist attackers by visiting specific websites and running downloaded files when prompted by phone calls. Which of the following would best address this issue?
- A. Blocking all scripts downloaded from the internet
- B. Increasing training and awareness for all staff
- C. Disabling all staff members' ability to run downloaded applications
- D. Ensuring that malicious websites cannot be visited
Answer: B
Explanation:
Explanation
Increasing training and awareness for all staff is the best way to address the issue of employees being enticed to assist attackers by visiting specific websites and running downloaded files when prompted by phone calls.
This issue is an example of social engineering, which is a technique that exploits human psychology and behavior to manipulate people into performing actions or divulging information that benefit the attackers.
Social engineering can take many forms, such as phishing, vishing, baiting, quid pro quo, or impersonation.
The best defense against social engineering is to educate and train the staff on how to recognize and avoid common social engineering tactics, such as:
Verifying the identity and legitimacy of the caller or sender before following their instructions or clicking on any links or attachments Being wary of unsolicited or unexpected requests for information or action, especially if they involve urgency, pressure, or threats Reporting any suspicious or anomalous activity to the security team or the appropriate authority Following the organization's policies and procedures on security awareness and best practices Official References:

NEW QUESTION # 32
Which of the following is the BEST option to protect a web application against CSRF attacks?
- A. Set a server-side rate limit for CSRF token generation.
- B. Avoid the transmission of CSRF tokens using cookies.
- C. Configure the web application to only use HTTPS and TLS 1.3.
- D. Update the web application to the latest version.
Answer: B
Explanation:
CSRF tokens are random values that are generated by the server and included in requests that perform state-changing actions. They are used to prevent CSRF attacks by verifying that the request originates from a legitimate source. However, if the CSRF tokens are transmitted using cookies, they are vulnerable to being stolen or forged by an attacker who can exploit other vulnerabilities, such as cross-site scripting (XSS) or cookie injection. Therefore, a better option is to avoid the transmission of CSRF tokens using cookies and use other methods, such as hidden form fields or custom HTTP headers.

NEW QUESTION # 33
Which of the following is the best reason why organizations need operational security controls?
- A. To supplement areas that other controls cannot address
- B. To limit physical access to areas that contain sensitive data
- C. To assess compliance automatically against a secure baseline
- D. To prevent disclosure by potential insider threats
Answer: A
Explanation:
Operational security controls are security measures that are implemented and executed by people rather than by systems. Operational security controls are needed to supplement areas that other controls, such as technical or physical controls, cannot address. For example, operational security controls can include policies, procedures, training, awareness, audits, reviews, testing, etc. These controls can help ensure that employees follow best practices, comply with regulations, detect and report incidents, and respond to emergencies. The other options are not specific to operational security controls or are too narrow in scope.
