Cybersecurity Technical Questions!

These are the continuation of the technical interview questions from last week's blog. Some important technical interview questions that might come up in a technical interview are as follows:

1) What is a traceroute? Why is it used?

Traceroute is a tool that shows the path of a packet. It lists all the points (mainly routers) that the packet passes through. This is used mostly when the packet is not reaching its destination. Traceroute is used to check where the connection stops or breaks to identify the point of failure.

2) What is the difference between HIDS and NIDS?

HIDS(Host IDS) and NIDS(Network IDS) are both Intrusion Detection Systems and work for the same purpose i.e., to detect intrusions. The only difference is that the HIDS is set up on a particular host/device. It monitors the traffic of a particular device and suspicious system activities. On the other hand, NIDS is set up on a network. It monitors traffic of all devices of the network.

3) Explain SSL Encryption

SSL(Secure Sockets Layer) is the industry-standard security technology creating encrypted connections between a Web Server and a Browser. This is used to maintain data privacy and to protect the information in online transactions.

4) What are some of the common Cyberattacks?

Following are some common cyber attacks that could adversely affect your system.
