What is Cryptography? Part A: Theoretical Cyber Security Interview Question 1.
The basic goal of using cryptography is to safeguard data from third parties for whom it was not intended. Cryptography is the practise and study of ways for securing information and communication.
- What distinguishes symmetric encryption from asymmetric encryption?
- How do IDS and IPS differ from one another?
The administrator must take charge of stopping the incursion once the IDS, or intrusion detection system, only discovers them. Contrarily, in an IPS, or intrusion prevention system, the system not only detects the intrusion but also takes steps to stop it.
- Describe the CIA trio.
Confidentiality, Integrity, and Availability is referred to as CIA. A model called CIA is intended to direct information security policy. It is one of the models that businesses utilise the most frequently.
Only authorised personnel should be able to access and view the information. It shouldn’t be available to anyone not authorised. Strong encryption should be used to protect the data just in case someone decides to hack into it.
ensuring that no unauthorised party has altered the data. Integrity guarantees that unauthorised individuals cannot corrupt or modify data. The data should be reverted back and should not be altered if an authorised person or system tries to edit it but is unsuccessful.
The user should have access to the data anytime they need it. It is important to take care of hardware maintenance, regular upgrades, data backups and recovery, and network bottlenecks.
- What distinguishes encryption from hashing?
The process of transforming readable data into an unreadable format uses both encryption and hashing. The distinction is that while the hashed data cannot be converted back to the original data, the encrypted data can be decrypted to return to the original data.
- What exactly is a firewall and how does it work?
A firewall is a type of network security device that is installed on a system’s or network’s perimeter and is used to monitor and manage network traffic. Firewalls are primarily used to safeguard systems and networks from malware, worms, and other threats. Firewalls can also be used to block content filtering and remote access.
What distinguishes penetration testing from vulnerability assessment (VA)?
Finding vulnerabilities on a system is called vulnerability assessment.
What sets encryption apart from hashing?
Both encryption and hashing are used to convert readable data into an unreadable format. The difference is that whilst the encrypted data can be decoded to get back to the original data, the hashed data cannot be converted back to the original data.
What is a firewall actually, and how does it operate?
A firewall is a sort of network security device used to monitor and control network traffic. It is situated on the perimeter of a system or network. In order to protect systems and networks from viruses, worms, and other dangers, firewalls are largely employed. Additionally, content filtering and remote access can be hindered by firewalls.
What separates vulnerability assessment (VA) from penetration testing?
- Describe traceroute. Why is it employed?
A tool that displays a packet’s path is called traceroute. It lists every location the packet passes through, primarily routers. This is typically used when a packet doesn’t get to its destination. To find the point of failure, Traceroute is used to look at where the connection drops or breaks.
- How do HIDS and NIDS differ from one another?
Both HIDS (Host IDS) and NIDS (Network IDS) are intrusion detection systems that serve the same objective—that is, to find intrusions. The HIDS is configured on a specific host or device, which is the only distinction. It keeps an eye on suspicious system activity and the traffic of a certain device. NIDS, on the other hand, is established on.
What does traceroute mean? What is its purpose?
The tool called Traceroute displays a packet’s journey. It includes a list of every location the packet passes through, primarily routers. This is mainly employed when a packet fails to arrive at its destination. In order to determine the point of failure, Traceroute is used to check where the connection drops or fails.
What distinguishes HIDS and NIDS from one another?
Both the HIDS (Host IDS) and NIDS (Network IDS) intrusion detection systems provide the same function, namely the detection of intrusions. The sole distinction is that the HIDS is configured on a specific host or device. It keeps track of suspicious system activity and a specific device’s traffic. However, NIDS is established on.
How do you configure a firewall?
The steps to install a firewall are as follows:
Username/password: Change a firewall device’s default password
Remote management: Disable the remote administration feature.
Forwarding of ports For some applications, such a web server or FTP server, to function effectively, configure the required port forwarding.
Server for DHCP: In the absence of disabling the firewall’s DHCP, installing a firewall on a network that already has a DHCP server will result in conflict.
Logging: Ensure that logging is enabled and learn how to view logs in order to fix firewall problems or potential assaults.
Security policies: Establish strong security policies and make sure the firewall is set up to enforce them.
Explain SSL Encryption in detail.
Secure Sockets Layer)
Layer) is the widely used security technique that establishes secure connections between a browser and a web server. This is done in order to safeguard online transaction information and guarantee data privacy. The following are the steps to setting up an SSL connection:
A browser tries to connect to a web server that is SSL-secured.
A copy of the browser’s SSL certificate is sent to the browser.
The SSL certificate’s trustworthiness is verified by the browser. If it is reliable, the browser notifies the web server that it wants to create an encrypted connection.
In order to establish an SSL-encrypted connection, the web server sends an acknowledgment.
Communication between the browser and the web server is SSL-encrypted 14. What actions are you going to a server secure?
