Q531. Joe analyzed the following log and determined the security team should implement which of the following as a mitigation method against further attempts?
Host 192.168.1.123
[00:
00: 01]Successful Login: 015 192.168.1.123 : local
[00:
00: 03]Unsuccessful Login: 022 214.34.56.006 : RDP 192.168.1.124
[00:
00: 04]UnSuccessful Login: 010 214.34.56.006 : RDP 192.168.1.124
[00:
00: 07]UnSuccessful Login: 007 214.34.56.006 : RDP 192.168.1.124
[00:
00: 08]UnSuccessful Login: 003 214.34.56.006 : RDP 192.168.1.124
A.
Reporting
B.
IDS
C.
Monitor system logs
D.
Hardening
Answer: D
Explanation:
We can see a number of unsuccessful login attempts using a Remote Desktop Connection (using the RDP protocol) from a computer with the IP address 192.168.1.124. Someone successfully logged in locally. This is probably an authorized login (for example, Joe logging in). Hardening is the process of securing a system. We can harden (secure) the system by either disallowing remote desktop connections altogether or by restricting which IPs are allowed to initiate remote desktop connections.
Q532. A software developer is responsible for writing the code on an accounting application. Another software developer is responsible for developing code on a system in human resources. Once a year they have to switch roles for several weeks.
Which of the following practices is being implemented?
A. Mandatory vacations
B. Job rotation
C. Least privilege
D. Separation of duties
Answer: B
Explanation:
A job rotation policy defines intervals at which employees must rotate through positions.
Q533. Which of the following implementation steps would be appropriate for a public wireless hot-spot?
A. Reduce power level
B. Disable SSID broadcast
C. Open system authentication
D. MAC filter
Answer: C
Explanation:
For a public wireless hot-spot, you want members of the public to be able to access the wireless network without having to provide them with a password. Therefore, Open System Authentication is the best solution.
Open System Authentication (OSA) is a process by which a computer can gain access to a wireless network that uses the Wired Equivalent Privacy (WEP) protocol. With OSA, a computer equipped with a wireless modem can access any WEP network and receive files that are not encrypted. For OSA to work, the service set identifier (SSID) of the computer should match the SSID of the wireless access point. The SSID is a sequence of characters that uniquely names a wireless local area network (WLAN). The process occurs in three steps. First, the computer sends a request for authentication to the access point. Then the access point generates an authentication code, usually at random, intended for use only during that session. Finally, the computer accepts the authentication code and becomes part of the network as long as the session continues and the computer remains within range of the original access point. If it is necessary to exchange encrypted data between a WEP network access point and a wireless-equipped computer, a stronger authentication process called Shared Key Authentication (SKA) is required.
Q534. Which of the following security account management techniques should a security analyst implement to prevent staff, who has switched company roles, from exceeding privileges?
A. Internal account audits
B. Account disablement
C. Time of day restriction
D. Password complexity
Answer: A
Explanation:
Internal account auditing will allow you to switch the appropriate users to the proper accounts required after the switching of roles occurred and thus check that the principle of least privilege is followed.
Q535. Key cards at a bank are not tied to individuals, but rather to organizational roles. After a break in, it becomes apparent that extra efforts must be taken to successfully pinpoint who exactly enters secure areas. Which of the following security measures can be put in place to mitigate the issue until a new key card system can be installed?
A. Bollards
B. Video surveillance
C. Proximity readers
D. Fencing
Answer: B
Explanation:
Video surveillance is making use of a camera, or CCTV that is able to record everything it sees and is always running. This way you will be able to check exactly who enters secure areas.

Q536. Which of the following was based on a previous X.500 specification and allows either unencrypted authentication or encrypted authentication through the use of TLS?
A. Kerberos
B. TACACS+
C. RADIUS
D. LDAP
Answer: D
Explanation:
The Lightweight Directory Access Protocol is an open, vendor-neutral, industry standard
application protocol for accessing and maintaining distributed directory information services over
an Internet Protocol (IP) network. Directory services play an important role in developing intranet
and Internet applications by allowing the sharing of information about users, systems, networks,
services, and applications throughout the network. As examples, directory services may provide
any organized set of records, often with a hierarchical structure, such as a corporate email
directory. Similarly, a telephone directory is a list of subscribers with an address and a phone
number.
A common usage of LDAP is to provide a "single sign on" where one password for a user is
shared between many services, such as applying a company login code to web pages (so that
staff log in only once to company computers, and then are automatically logged into the company
intranet).
LDAP is based on a simpler subset of the standards contained within the X.500 standard.
Because of this relationship, LDAP is sometimes called X.500-lite.
A client starts an LDAP session by connecting to an LDAP server, called a Directory System
Agent (DSA), by default on TCP and UDP port 389, or on port 636 for LDAPS. Global Catalog is
available by default on ports 3268, and 3269 for LDAPS. The client then sends an operation
request to the server, and the server sends responses in return.
The client may request the following operations:
StartTLS — use the LDAPv3 Transport Layer Security (TLS) extension for a secure connection
Q537. A software developer wants to prevent stored passwords from being easily decrypted. When the password is stored by the application, additional text is added to each password before the password is hashed. This technique is known as:
A. Symmetric cryptography.
B. Private key cryptography.
C. Salting.
D. Rainbow tables.
Answer: C
Explanation:
Salting can be used to strengthen the hashing when the passwords were encrypted. Though hashing is a one-way algorithm it does not mean that it cannot be hacked. One method to hack a hash is though rainbow tables and salt is the counter measure to rainbow tables. With salt a password that you typed in and that has been encrypted with a hash will yield a letter combination other than what you actually types in when it is rainbow table attacked.
Q538. Pete, the compliance manager, wants to meet regulations. Pete would like certain ports blocked only on all computers that do credit card transactions. Which of the following should Pete implement to BEST achieve this goal?
A. A host-based intrusion prevention system
B. A host-based firewall
C. Antivirus update system
D. A network-based intrusion detection system
Answer: B
Explanation:
A host-based firewall is installed on a client system and is used to protect the client system from the activities of the user as well as from communication from the network or Internet.
Q539. Which of the following allows Pete, a security technician, to provide the MOST secure wireless implementation?
A. Implement WPA
B. Disable SSID
C. Adjust antenna placement
D. Implement WEP
Answer: A
Explanation: Of the options supplied, WiFi Protected Access (WPA) is the most secure and is the replacement for WEP.
