Which of the following is a disadvantage of host based IDS Mcq?

What is a disadvantage of a host-based IDS?

Although monitoring the host is logical, it has three significant drawbacks: Visibility is limited to a single host; the IDS process consumes resources, possibly impacting performance on the host; and attacks will not be seen until they have already reached the host.

What are the characteristics of host-based IDS?

A host-based IDS is an intrusion detection system that monitors the computer infrastructure on which it is installed, analyzing traffic and logging malicious behavior. An HIDS gives you deep visibility into what’s happening on your critical security systems.

What is an advantage of a network-based IDS?

Benefits • NIDS identify and prevent security threats from compromising secure networks. The deployment of NIDS has little impact on network performance. NIDS are usually passive devices that listen on a network without interfering with the normal operation of a network.

What is a disadvantage of a host-based IDS quizlet?

– The IDS can have a high cost of ownership and maintenance. – The IDS must have a process on every system you want to watch. – The IDS is ineffective when traffic is encrypted. The IDS is ineffective when traffic is encrypted.

What is a major advantage of a host-based IDS and host based logging over a network-based IDS and network level logging?

The main advantage of using a host based prevention system is that since the protection system is integrated with the host itself, it is very easy to point out whether the actual attack has been successful or not.

What is the disadvantage of an IDS producing a high number of false positive results?

With too much traffic to process, an IDS may drop packets and be unable to detect attacks. 2. Sending to the IDS non-attack packets that are specially crafted to trigger many signatures within the IDS, thereby overwhelming the IDS’s human operator with false positives or crashing alert processing or display tools. 3.

What are strengths of the host-based IDS?

A host-based Intrusion Detection System resides on the system being monitored and tracks changes made to important files and directories with ability to monitor events local to a host. One of the advantages of host-based IDS is that it does not have to look for patterns, only changes within a specify set of rules.

Which of the following can be classified under advantages and disadvantages of OFB mode?

Which of the following can be classified under advantages and disadvantages of OFB mode? Explanation: Advantages: More resistant to transmission errors. A bit error in a ciphertext segment affects only the decryption of that segment.

What is not advantages of host based IDS *?


Host based IDSs are not well suited for detecting network scans or other such surveillance that targets an entire network. Host-based IDSs can be disabled by certain denial-of- service attacks.

Which of the following is a drawback of network-based IPS?

Possibly the biggest drawback to network-based monitoring is that as networks become larger (with respect to bandwidth), it becomes more difficult to place network IPS at a single location in the network and successfully capture all the traffic.

What is the role of a host based firewall in network defense?

A host-based firewall is a piece of firewall software that runs on an individual computer or device connected to a network. These types of firewalls are a granular way to protect the individual hosts from viruses and malware, and to control the spread of these harmful infections throughout the network.
