Question#2

Users are claiming that a web server is not accessible. A security engineer logs for the site.
The engineer connects to the server and runs netstat -an and receives the following output:

Which of the following is MOST likely happening to the server?

A. Port scanning

B. ARP spoofing

C. Buffer overflow

D. Denial of service

Explanation:
A denial of service (DoS) attack is a malicious attempt to disrupt the normal functioning of a server by overwhelming it with requests or traffic1. One possible indicator of a DoS attack is a large number of connections from a single source IP address1. In this case, the output of netstat -an shows that there are many connections from 213.37.55.67 with different port numbers and in TIME WAIT state23. This suggests that the attacker is sending many SYN packets to initiate connections but not completing them, thus exhausting the server’s resources and preventing legitimate users from accessing it1.

Question#3

A security administrator configured the account policies per security implementation guidelines.
However, the accounts still appear to be susceptible to brute-force attacks.
The following settings meet the existing compliance guidelines:
Must have a minimum of 15 characters
Must use one number
Must use one capital letter
Must not be one of the last 12 passwords used
Which of the following policies should be added to provide additional security?

A. Shared accounts

B. Password complexity

C. Account lockout

D. Password history

E. Time-based logins

Question#4

A software developer created an application for a large, multinational company. The company is concerned the program code could be reverse engineered by a foreign entity and intellectual property would be lost.
Which of the following techniques should be used to prevent this situation?

A. Obfuscation

B. Code signing

C. Watermarking

D. Digital certificates

Explanation:
Obfuscation is a technique used to make the program code difficult to understand or read. It can help to prevent reverse engineering by making it more challenging to analyze the code and understand its structure and functionality, thereby protecting intellectual property.

Question#5

The Chief Security Officer (CSO) requested the security team implement technical controls that meet the following requirements:
* Monitors traffic to and from both local NAS and cloud-based file repositories
* Prevents on-site staff who are accessing sensitive customer Pll documents on file repositories from accidentally or deliberately sharing sensitive documents on personal Saa$S solutions
* Uses document attributes to reduce false positives
* Is agentless and not installed on staff desktops or laptops
Which of the following when installed and configured would BEST meet the CSO's requirements? (Select TWO).

A. DLP

B. NGFW

C. UTM

D. UEBA

E. CASB

F. HIPS

Explanation:
DLP, or data loss prevention, and CASB, or cloud access security broker, are the solutions that when installed and configured would best meet the CSO’s requirements. DLP is a technology that monitors and prevents unauthorized or accidental data leakage or exfiltration from an organization’s network or devices. DLP can use document attributes, such as metadata, keywords, or fingerprints, to identify and classify sensitive data and enforce policies on how they can be accessed, transferred, or shared. CASB is a technology that acts as a proxy or intermediary between an organization’s cloud services and its users. CASB can provide visibility, compliance, threat protection, and data security for cloud-based applications and data. CASB can also prevent on-site staff from accessing personal SaaS solutions that are not authorized by the organization.
