You are reviewing a rule within your organization’s IDS. You see the following output: Based on this rule, which of the following malicious packets would this IDS alert on?
A. A malicious outbound TCP Packet

B. A malicious outbound packets

C. A malicious inbound TCP Packet

D. A malicious inbound packets

C. A malicious inbound TCP Packet

OBJ-3.3: The rule header is set to alert only on TCP packets based on this IDS rule’s first line. The flow condition is set as “to_client, established,” which means that only inbound traffic will be analyzed against this rule and only inbound traffic for connections that are already established. Therefore, this rule will alert on an inbound malicious TCP packet only when the packet matches all the conditions listed in this rule. This rule is an example of a Snort IDS rule. For the exam, you do not need to create your own IDS rules, but you should be able to read them and pick out generic content like the type of protocol covered by the signature, the port to be analyzed, and the direction of flow.

(Sample Simulation – On the real exam for this type of question, you would have to fill in the blanks by dragging and dropping them into place.) Using the image provided, select four security features that you should use with a workstation or laptop within your organization? A. CAT5e STP, Location Tracking, Host Based firewall, Remote Wipe B. Host Based firewall, Network Sniffer, Cable Lock, CAT5e STP C. Cable Lock, Network Sniffer, Host Based firewall, Remote wipe D. Remote Wipe, Location Tracking, Host Based firewall, CableLock

B. Host Based firewall, Network Sniffer, Cable Lock, CAT5e STP OBJ-3.5: Host-based firewall, Network sniffer, a Cable lock, and CAT5e STP cables are appropriate security features to use with a corporate workstation or laptop. Using a host-based firewall (such as Windows Firewall), you can configure the workstation or laptop to block incoming or outgoing data from the device's network connection. If you install a network sniffer, you will be able to capture any network traffic used on the network for later analysis. If you use a cable lock, it will lock the workstation or laptop to a desk and prevent theft of the device. If you use a CAT 5e STP cable for your network connection, you will minimize EMI risk and reduce data emanations.

By using cellular data, your users will be able to avoid connecting to WiFi networks for connectivity. Remote wipe enables the organization to remotely erase the device's contents if it is lost or stolen. Location tracking uses the smart phone’s GPS coordinates for certain apps, location-based authentication, and to track down a device if it is lost or stolen. Mobile device management (MDM) programs enable the administrators to remotely push software updates, security policies, and other security features to the device from a centralized server.
