When visiting an office adjacent to the server room, you discover the lock to the window is broken. Because it is not your office you tell the resident of the office to contact the maintenance person and have it fixed. After leaving, you fail to follow up on whether the windows was actually repaired. What affect will this have on the likelihood of a threat associated with the vulnerability actually occurring? If the window is repaired, the likelihood of the threat occurring will increase. B. If the window is repaired, the likelihood of the threat occurring will remain constant. C. If the window is not repaired the, the likelihood of the threat occurring will decrease. D. If the window is not repaired, the likelihood of the threat occurring will increase.

If the window is repaired, the likelihood of the threat occurring will increase.
If the window is repaired, the likelihood of the threat occurring will remain constant.
If the window is not repaired the, the likelihood of the threat occurring will decrease.
If the window is not repaired, the likelihood of the threat occurring will increase.

Correct Answer

A. If the window is not repaired, the likelihood of the threat occurring will increase.

Explanation

In this scenario, the broken window serves as a vulnerability that could potentially be exploited by a threat. If the window is not repaired, the vulnerability remains, and the likelihood of the threat occurring increases because there is still an avenue for unauthorized access or security breaches. Failure to address and mitigate known vulnerabilities can lead to an increased risk of threats being realized. For -> ( Reference: Security + (SYBEX) page 87 )

A company consists of the main building with two smaller branch offices at opposite ends of the city. The main building and branch offices are connected with fast links so that all employees have good connectivity to the network. Each of the buildings has security measures that require visitors to sign in, and all employees are required to wear identification badges at all times. You want to protect servers and other vital equipment so that the company has the best level of security at the lowest possible cost. Which of the following will you do to achieve this objective?

Centralize servers and other vital components in a single room of the main building, and add security measures to this room so that they are well protected.
Centralize most servers and other vital components in a single room of the main building, and place servers at each of the branch offices. Add security measures to areas where the servers and other components are located.
Decentralize servers and other vital components, and add security measures to areas where the servers and other components are located.
main building. Because the building prevents unauthorized access to visitors and other persons, there is no need to implement physical security in the server room.

Correct Answer

A. Centralize servers and other vital components in a single room of the main building, and add security measures to this room so that they are well protected.

Explanation

For -> ( Keep in mind that cost and best level of security is asked for. To keep all the servers in one room along with the vital components with a security measure added to the room will provide what is asked for.)

You are explaining SSL to a junior administrator and come up with the topic of handshaking. How many steps are employed between the client and server in the SSL handshake process?

Five
Six
Seven
Eight

Correct Answer

A. Six

Explanation

For -> ( Graphical explanation of 6 steps to Digital Handshake for SSL ) For -> ( Note: The handshake begins when a browser connects to an SSL-enabled server and asks the server to send back its identification, a digital certificate that usually contains the server name, the trusted certifying authority, and the server public encryption key. The browser can contact the server of the trusted certifying authority and confirm that the certificate is authentic before proceeding. The browser then presents a list of encryption algorithms and hashing functions (used to generate a number from another); the server picks the strongest encryption that it also supports and notifies the client of the decision. In order to generate the session keys used for the secure connection, the browser uses the server public key from the certificate to encrypt a random number and send it to the server. The client can encrypt this data, but only the server can decrypt it: this is the one fact that makes the keys hidden from third parties, since only the server and the client have access to this data. The server replies with more random data (which doesn’t have to be encrypted), and then both parities use the selected hash functions on the random data to generate the session keys. This concludes the handshake and begins the secured connection, which is encrypted and decrypted with the session keys. The SSL handshake allows the establishment of a secured connection over an insecure channel. Even if a third party were to listen to the conversation, it would not be able to obtain the session keys. The process of creating good random numbers and applying hash functions can be quite slow, but usually the session keys are cached, so the handshake occurs only on the first connection between the parties. This process works on top of HTTP, so it's portable to any platform that supports it and is in principle applicable to other protocols as well (Welling 2001, p.334). The process described is part of SSL version 2.0, but version 3.0 is supposed to replace it soon. Another standard, Transport Layer Security (TSL) is still in draft and is supposed to replace SSL in the future.)

You have been alerted to the possibility of someone using an application to capture and manipulate packets as they are passing through your network. What type of threat does this represent? A. DDos B. Back Door C. Spoofing D. Man in the Middle

DDos
Trojan Horse
Logic Bomb
Man-in-the-middle

Correct Answer

A. Man-in-the-middle

Explanation

For -> ( The method used in these attacks place a piece of software between a server and the user. The software intercepts and then sends the information to the server. The server responds back to the software, thinking it is the legitimate client. The attacking software then sends this information on to the server, etc. The man in the middle software may be recording this information, altering it, or in some other way compromising the security of your system.)

A problem with air conditioning is causing fluctuations in temperature in the server room. The temperature is rising to 90 degrees when the air conditioner stops working and then drops to 60 degrees when it starts working again. The problem keeps occurring over the next two days. What problem may result from these fluctuations?

Electrostatic discharge
Power outages
Chip creep
Poor air quality

Correct Answer

A. Chip creep

Explanation

For -> ( The expansion and contraction that occurs during the normal heating and cooling cycles of your system can cause chips and cards, over time, to inch lose from sockets or slots.)

While connected from home to an ISP (Internet Service Provider), a network administrator performs a port scan against a corporate server and encounters four open TCP (Transmission Control Protocol) ports: 25, 110, 143, and 389. Corporate users in the organization must be able to connect from home, send and receive messages on the Internet, read e-mail by beams of the IMAPv.4 (Internet Message Access Protocol version 4) protocol, and search into a directory services database for user e-mail addresses, and digital certificates. All the e-mail relates services, as well as the directory server, run on the scanned server. Which of the above ports can be filtered out to decrease unnecessary exposure without affecting functionality?

25
110
143
389

Correct Answer

A. 110

Explanation

For -> ( Internet Message Access Protocol v4 uses port 143 and TCP for connections. POP3 uses port 110 and TCP for connections and therefore can be filtered out to decrease unnecessary exposure.)
