Which task can you perform to log all packets that are dropped by the firewall on your computer?
The Workload Security stateful firewall configuration mechanism analyzes each packet in the context of traffic history, correctness of TCP and IP header values, and TCP connection state transitions. In the case of stateless protocols like UDP and ICMP, a pseudo-stateful mechanism is implemented based on historical traffic analysis. Packets are handled by the stateful mechanism as follows: Show
To create a new stateful configuration, you need to:
When you're done with your stateful configuration, you can also learn how to
Add a stateful configurationThere are three ways to define a stateful configuration on the Policies > Common Objects > Other > Firewall Stateful Configurations page:
Enter stateful configuration informationEnter a Name and Description for the configuration. Select packet inspection optionsYou can define options for IP, TCP, UDP and ICMP packet inspection, end enable Active or Passive FTP. IP packet inspectionUnder the General tab, select the Deny all incoming fragmented packets to drop any fragmented packets. Dropped packets will bypass fragmentation analysis and generate an "IP fragmented packet" log entry. Packets with a total length smaller than the IP header length are dropped silently. Attackers sometimes create and send fragmented packets in an attempt to bypass Firewall Rules. The Firewall Engine, by default, performs a series of checks on fragmented packets. This is default behavior and cannot be reconfigured. Packets with the following characteristics are dropped:
TCP packet inspectionUnder the TCP tab, select which of the following options you would like to enable:
FTP OptionsUnder the FTP Options tab, you can enable the following options: The following FTP options are available in version 8.0 and earlier agents.
UDP packet inspectionUnder the UDP tab, you can enable the following options:
ICMP packet inspectionUnder the ICMP tab, you can enable the following options: ICMP stateful inspection is available in version 8.0 or earlier agents.
Export a stateful configurationYou can export all stateful configurations to a .csv or .xml file by clicking Export and selecting the corresponding export action from the list. You can also export specific stateful configurations by first selecting them, clicking Export and then selecting the corresponding export action from the list. Delete a stateful configurationTo delete a stateful configuration, right-click the configuration in the Firewall Stateful Configurations list, click Delete and then click OK. Stateful configurations that are assigned to one or more computers or that are part of a policy cannot be deleted. See policies and computers a stateful configuration is assigned toYou can see which policies and computers are assigned to a stateful inspection configuration on the Assigned To tab. Click on a policy or computer in the list to see their properties. How does a firewall prevent unauthorized access to a computer system?A firewall can help protect your computer and data by managing your network traffic. It does this by blocking unsolicited and unwanted incoming network traffic. A firewall validates access by assessing this incoming traffic for anything malicious like hackers and malware that could infect your computer.
What type of firewall inspects network traffic at a higher level in the OSI model than a traditional stateful packet inspection firewall does?A proxy firewall (aka application-level gateway) inspects packets at the application layer of the Open Systems Interconnection (OSI) reference model.
Where are users Kerberos tickets and other security related information stored?Where are the user's kerberos tickets and other security-related information stored? Local security authority.
How can you encrypt the contents of the C :\ Data folder so that Kate and Rodney are the only authorized users?How can you encrypt the contents of the C:\Data folder so that Kate and Rodney are the only authorized users? Instruct Rodney to log on to his computer, edit the properties of the C:\Data Folder, and enable encryption. Add Kate as an authorized user for each file in the C:\Data folder.
