Movate Network Security Interview Questions, Process, and Tips

RSA stands for Rivest-Shamir-Adleman, a widely used encryption algorithm for secure communication.

• RSA is a public-key cryptosystem used for secure data transmission.

• It involves generating a public key and a private key for encryption and decryption.

• RSA encryption is based on the difficulty of factoring large prime numbers.

• It is commonly used in secure communication protocols like HTTPS.

• RSA can be used for digital signa

Basic principles of security management involve risk assessment, access control, incident response, and security awareness.

• Risk assessment: Identifying and evaluating potential risks to the organization's security.

• Access control: Implementing measures to control who has access to sensitive information or resources.

• Incident response: Developing plans and procedures to respond to security incidents effectively.

• Security a...read more

OWASP stands for Open Web Application Security Project, a non-profit organization focused on improving software security.

• OWASP provides resources such as tools, documentation, and guidelines for web application security.

• It publishes a list of the top 10 most critical web application security risks.

• OWASP also offers training and conferences to educate professionals on security best practices.

3 way hand shaking is a process in TCP/IP communication where three packets are exchanged to establish a connection.

• Three packets are involved: SYN, SYN-ACK, ACK

• SYN packet is sent by the client to the server to initiate the connection

• SYN-ACK packet is sent by the server to the client as a response

• ACK packet is sent by the client to the server to confirm the connection

The OSI Model is a conceptual framework that standardizes the functions of a telecommunication or computing system into seven layers.

• The OSI Model stands for Open Systems Interconnection Model.

• It helps in understanding how data is transferred between devices in a network.

• Each layer has specific functions and communicates with the adjacent layers.

• Examples of layers include Physical, Data Link, Network, Transport, Sessio

TCP is connection-oriented, reliable, and slower, while UDP is connectionless, unreliable, and faster.

• TCP is connection-oriented, meaning it establishes a connection before sending data, while UDP is connectionless.

• TCP is reliable as it ensures all data is received in order and without errors, while UDP does not guarantee delivery.

• TCP is slower due to the overhead of establishing and maintaining connections, while UDP ...read more

A firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules.

• Acts as a barrier between a trusted internal network and untrusted external network

• Filters traffic based on rules set by the network administrator

• Can be hardware-based or software-based

• Examples include Cisco ASA, Palo Alto Networks, and pfSense

Prioritizing and remediating vulnerabilities using OWASP Top 10

• Start by identifying the vulnerabilities that pose the highest risk to the organization

• Use the OWASP Top 10 as a guide to prioritize vulnerabilities

• Consider the likelihood and potential impact of each vulnerability

• Remediate vulnerabilities based on their priority level

• Perform regular vulnerability assessments to stay up-to-date on new vulnerabilities

• Example...read more

Malware refers to malicious software designed to disrupt, damage, or gain unauthorized access to a computer system.

• Viruses: self-replicating programs that infect other files on a computer

• Worms: standalone malware that spreads across networks

• Trojans: disguised as legitimate software to trick users into installing them

• Ransomware: encrypts files and demands payment for decryption

• Spyware: secretly gathers information about...read more

The first step would be to isolate the infected machine from the network to prevent further spread of the infection.

• Isolate the infected machine from the network to prevent further spread of the infection

• Identify the type of malware or virus that has infected the machine

• Run a full system scan using antivirus software to detect and remove the malware

• Update the operating system and all software to patch any vulnerabiliti...read more

Designing HA in active passive environment involves ensuring redundancy and failover mechanisms.

• Identify critical components and services that require high availability

• Implement redundancy by setting up a secondary system that can take over in case of failure

• Ensure automatic failover mechanisms are in place to minimize downtime

• Regularly test the failover mechanisms to ensure they work as expected

• Consider load balancing...read more
