Q571. Which of the following is an important implementation consideration when deploying a wireless network that uses a shared password? 

A. Authentication server 

B. Server certificate

Q572. Which of the following can Joe, a security administrator, implement on his network to capture attack details that are occurring while also protecting his production network? 

A. Security logs 

B. Protocol analyzer 

C. Audit logs 

D. Honeypot 

Answer:

Explanation: 

A honeypot is a system whose purpose it is to be attacked. An administrator can watch and study 

the attack to research current attack methodologies. 

According to the Wepopedia.com, a Honeypot luring a hacker into a system has several main 

purposes: 

The administrator can watch the hacker exploit the vulnerabilities of the system, thereby learning 

where the system has weaknesses that need to be redesigned. 

The hacker can be caught and stopped while trying to obtain root access to the system. 

By studying the activities of hackers, designers can better create more secure systems that are 

potentially invulnerable to future hackers. 

There are two main types of honeypots: 

Production – A production honeypot is one used within an organization's environment to help 

mitigate risk. 

Research – A research honeypot add value to research in computer security by providing a platform to study the threat. 

Q573. Which of the following can BEST help prevent cross-site scripting attacks and buffer overflows on a production system? 

A. Input validation 

B. Network intrusion detection system 

C. Anomaly-based HIDS 

D. Peer review 

Answer:

Explanation: 

Input validation is a defensive technique intended to mitigate against possible user input attacks, such as buffer overflows and fuzzing. Input validation checks every user input submitted to the application before processing that input. The check could be a length, a character type, a language type, or a domain. 

Q574. Pete, the system administrator, wishes to monitor and limit users’ access to external websites. 

Which of the following would BEST address this? 

A. Block all traffic on port 80. 

B. Implement NIDS. 

C. Use server load balancers. 

D. Install a proxy server. 

Answer:

Explanation: 

A proxy is a device that acts on behalf of other(s). In the interest of security, all internal user interaction with the Internet should be controlled through a proxy server. The proxy server should automatically block known malicious sites. The proxy server should cache often-accessed sites to improve performance. 

Q575. Which of the following can a security administrator implement on mobile devices that will help prevent unwanted people from viewing the data if the device is left unattended? 

A. Screen lock 

B. Voice encryption 

C. GPS tracking 

D. Device encryption 

Answer:

Explanation: 

Screen-lock is a security feature that requires the user to enter a PIN or a password after a short period of inactivity before they can access the system again. This feature ensures that if your device is left unattended or is lost or stolen, it will be difficult for anyone else to access your data or applications. 

Q576. Which of the following malware types is MOST likely to execute its payload after Jane, an employee, has left the company? 

A. Rootkit 

B. Logic bomb 

C. Worm 

D. Botnet 

Answer:

Explanation: 

This is an example of a logic bomb. The logic bomb is configured to ‘go off’ or when Jane has left the company. A logic bomb is a piece of code intentionally inserted into a software system that will set off a malicious function when specified conditions are met. For example, a programmer may hide a piece of code that starts deleting files should they ever be terminated from the company. Software that is inherently malicious, such as viruses and worms, often contain logic bombs that execute a certain payload at a pre-defined time or when some other condition is met. This technique can be used by a virus or worm to gain momentum and spread before being noticed. Some viruses attack their host systems on specific dates, such as Friday the 13th or April Fool's Day. Trojans that activate on certain dates are often called "time bombs". To be considered a logic bomb, the payload should be unwanted and unknown to the user of the software. As an example, trial programs with code that disables certain functionality after a set time are not normally regarded as logic bombs. 

Q577. The Chief Technical Officer (CTO) has tasked The Computer Emergency Response Team (CERT) to develop and update all Internal Operating Procedures and Standard Operating Procedures documentation in order to successfully respond to future incidents.

Which of the following is an application security technique that can be used to identify unknown weaknesses within the code? 

A. Vulnerability scanning 

B. Denial of service 

C. Fuzzing 

D. Port scanning 

Answer:

Explanation: 

Fuzzing is a software testing technique that involves providing invalid, unexpected, or random data to as inputs to a computer program. The program is then monitored for exceptions such as crashes, or failed validation, or memory leaks.

A. To ensure proper use of social media 

B. To reduce organizational IT risk 

C. To detail business impact analyses
