Basic Interview Questions

Sample Answer:

Advantages

Disadvantages

It can be used to foil security attacksIt creates massive security issues
To plug the bugs and loopholesGet unauthorized system access
It helps to prevent data theftIt helps to prevent data theft
Hacking prevents malicious attacksViolating privacy regulations

 

Sample Answer:

Asymmetric encryption

Symmetric encryption

Asymmetric encryption uses different keys for encryption and decryption.Symmetric encryption uses the same key for both encryption and decryption.
Asymmetric on the other hand is more secure but slow. Hence, a hybrid approach should be preferred.Symmetric is usually much faster but the key needs to be transferred over an unencrypted channel.

 

Sample Answer:

ARP poisoning is a type of network attack that can be resolved through these techniques:Using Packet filtering: Packet filters can filter out & block packets with clashing source address data.

Keeping away from trust relationship: Organizations ought to develop a protocol that depends on trust relationship as little as they can.

Utilize ARP spoofing software: Some programs assess and certify information before it is transmitted and blocks any information that is spoofed.

Sample Answer:

Footprinting is nothing but accumulating and revealing as much as data about the target network before gaining access into any network. Open Source Footprinting : It will search for the contact data of administrators that will be utilized for guessing password in Social Engineering Network Enumeration : The hacker attempts to distinguish the domain names and the network blocks of the target network Scanning : After the network is known, the second step is to spy the active IP addresses on the network. For distinguishing active IP addresses (ICMP) Internet Control Message Protocol is a functioning IP addresses Stack Fingerprinting : the final stage of foot printing step can be performed, once the hosts and port have been mapped by examining the network, this is called Stack fingerprinting.

Sample Answer:

Sample Answer:

A firewall could be a device that allows/blocks traffic as per outlined set of rules. These are placed on the boundary of trusted and untrusted networks.

 

Sample Answer:

Hacking, or targeting on a machine, should have the following 5 phases :
Surveillance : This is the principal stage where the hacker endeavours to gather as much data as possible about the target

Scanning : This stage includes exploiting the data accumulated amid Surveillance stage and utilizing it to inspect the casualty. The hacker can utilize computerized devices amid the scanning stage which can incorporate port scanners, mappers and vulnerability scanners.

Getting access : This is where the real hacking happens. The hacker attempts to exploit data found amid the surveillance and Scanning stage to get access.
Access Maintenance : Once access is gained, hackers need to keep that access for future exploitation and assaults by securing their exclusive access with backdoors, rootkits and Trojans.

Covering tracks : Once hackers have possessed the capacity to pick up and maintain access, they cover their tracks and to keep away from getting detected. This likewise enables them to proceed with the utilization of the hacked framework and keep themselves away from legitimate activities.
