In retrospect, you have learned about host-based intrusion detection systems (HIDS) and network-based intrusion detection systems (NIDS). Read this article on intrusion detection systems and note the strengths of HIDS and NIDS, and the overall pros and cons of intrusion detection systems.

4. PROS AND CONS OF INTRUSION DETECTION SYSTEMS

Pros of IDS are as follows:

    • Detects external hackers and network-based attacks.
    • Offers centralized management for correlation of distributed attacks.
    • Provides the system administrator the ability to quantify attacks.
    • Provides an additional layer of protection.
    • Provides defense in depth.

Cons of IDS are as follows:

    • Generates false positives and negatives.
    • Require full-time monitoring.
    • It is expensive
    • Require highly skilled staffs.

Advantages and disadvantages of HIDS

Advantages:-

  1. Verifies success or failure of an attack: Since a host based IDS uses system logs containing events that have actually occurred, they can determine whether an attack occurred or not.
  2. Monitors System Activities: A host based IDS sensor monitors user and file access activity including file accesses, changes to file permissions, attempts to install new executables etc.
  3. Detects attacks that a network based IDS fail to detect: Host based systems can detect attacks that network based IDS sensors fail to detect. For example, if an unauthorized user makes changes to system files from the system console, this kind of attack goes unnoticed by the network sensors.
  4. Near real time detection and response: Although host based IDS does not offer true real-time response, it can come very close if implemented correctly.
  5. Lower entry cost: Host based IDS sensors are far cheaper than the network based IDS sensors.

Disadvantages:-

  1. Host based IDSs are harder to manage, as information must be configured and managed for every host.
  2. The information sources for host based IDSs reside on the host targeted by attacks, the IDSs may be attacked and disabled as part of the attack.
  3. Host based IDSs are not well suited for detecting network scans or other such surveillance that targets an entire network.
  4. Host-based IDSs can be disabled by certain denial-of- service attacks.

What is a disadvantage of using an IDS?

The disadvantage to host-based IDS is its inability to discover network threats against the host. On the other hand, network-based IDS utilizes network sensors strategically placed throughout the network, allowing the system to detect reconnaissance attacks.

What are the advantages of host

Benefits • HIDS can detect attacks that cannot be seen by a Network-Based IDS since they monitor events local to a host. HIDS can often operate in an environment where network traffic is encrypted. HIDS are unaffected by switched networks.

What is the disadvantage of anomaly based IDS?

The disadvantage here is that many non-malicious behaviors will get flagged simply for being atypical. The increased likelihood for false positives with anomaly-based intrusion detection can require additional time and resources to investigate all the alerts to potential threats.

What is an advantage of a host

439) What is an advantage of a host-based IDS? A. It can reduce false-positive rates.

What is the advantage of using a network

The host-based intrusion detection system can detect internal changes (e.g., such as a virus accidentally downloaded by an employee and spreading inside your system), while a network-based IDS will detect malicious packets as they enter your network or unusual behavior on your network such as flooding attacks or ...
