Answer No 1:

Security technologies called intrusion detection systems (IDS) are created to identify and address security risks in a network. The following are some benefits and drawbacks of utilizing IDS as a network security tool:

Advantages:

Real-time detection: IDS can identify security risks as they develop, allowing administrators to stop an attack right away.

Wide coverage: IDS is a useful tool for identifying threats throughout the entire network since it can keep an eye on a lot of network devices and traffic.

Compliance: By keeping an eye out for specific traffic patterns or activities that are against the law, IDS can assist enterprises in meeting compliance obligations.

Network visibility: IDS can give administrators in-depth knowledge of network activity, enabling them to spot patterns and trends that could be signs of possible security risks.

Limitations:

False positives: IDS may issue alarms for traffic that is not dangerous, which may necessitate pointless inquiry and resource usage.

Limited ability to respond: IDS is only capable of detecting threats and producing alerts; it is unable to take action to thwart attacks or lessen their effects.

Failure to recognize novel threats: Since IDS relies on recognized signatures and patterns to identify threats, it could fail to recognize novel or unidentified threats.

Impact on network performance: IDS may have an adverse effect on network performance by using up network resources, especially in contexts with high traffic.

Answer No 2:

By adhering to the following best practices, organizations can most effectively use intrusion detection systems (IDS) to improve their overall network security posture:

Determine which network assets need to be monitored: Organizations should determine which critical network assets, such as servers, databases, and other sensitive data, need to be monitored. As a result, the IDS is directed toward the network's most important nodes.

Create specialized rules: Organizations should create specialized IDS rules based on the network assets being watched. This makes sure that the IDS is concentrated on identifying and notifying users of a particular sort of traffic that may be a threat to those assets.

Ensure IDS software is current: Organizations should make sure the IDS software is current with the newest security patches and updates. By doing so, you can increase the IDS's capacity for spotting and combating contemporary threats.

setup the IDS to provide alerts to the proper personnel: Organizations should setup the IDS to send alerts to the proper personnel when a security danger is discovered. Because of this, the company is better able to respond to threats swiftly and lessen their potential effects.

IDS alerts should be routinely reviewed and analyzed by organizations, who should also do so. This makes it possible for the company to take preventative action to reduce security threats by identifying trends and patterns that may point to potential dangers.
