Importance of Cyber Security Engineer

  • Protection against Cyber Threats

By proactively discovering and addressing vulnerabilities and preventing cyberattacks, cyber security engineers are essential to protecting an organization’s digital assets, including

a) Sensitive Data and

b) Intellectual Property.

  • Compliance and Regulatory Requirements

They help the company avoid the legal and financial repercussions connected with non-compliance by ensuring that the business conforms with industry-specific rules and data protection laws.

  • Business Continuity

Engineers in cyber security contribute to the continuity of operations by averting disruptions brought on by cyber incidents. Through their work, organizations are able to maintain customer service and accomplish their goals despite cyber threats.

  • Reputation Management

A cybersecurity incident can harm a company’s brand and decrease consumer and partner trust. By preventing these occurrences, cyber security engineers support the upkeep of the company’s credibility and reputation.

  • Cost Savings

Dealing with the fallout from a successful cyberattack is frequently more expensive than early detection and mitigation of cyber threats. By proactively defending against breaches and events, cyber security engineers help to lessen their financial toll.

Top 10 Important Questions for Cyber Security Engineer

  1. What is Cryptography?

In order to secure communication and data from unauthorized access or alteration, cryptography is the science and practice of putting information into a code or cipher. Information is encrypted and decrypted using mathematical methods and keys to ensure its

a) Secrecy,

b) Integrity, and

c) cyber security engineer.

2. What is the difference between Symmetric and Asymmetric encryption?

Symmetric encryption is faster but requires secure key distribution because it utilizes the same key for both encryption and decryption. Asymmetric encryption is slower but does away with the necessity for safe key exchange because it uses a pair of public and private keys.

3. What is the difference between IDS and IPS?

The IDS (Intrusion Detection System) scans network traffic for any suspicious behavior and sends out notifications when it finds anything that could be a threat.

IPS (Intrusion Prevention System) is a proactive protection system that not only recognizes threats but also automatically blocks or prevents them from compromising the network.

4. Explain the CIA triad.

A key idea in information security and cybersecurity is the CIA triad:

  • Confidentiality: It speaks about safeguarding private data from illegal access or exposure. ensuring that confidential data can only be accessed and seen by approved people or systems.
  • Integrity: This entails maintaining the data’s accuracy and dependability and making sure that no unauthorized individuals have tampered with or altered it.
  • Availability: In order to avoid disruptions or downtime, it makes sure that information and resources are constantly accessible and available to authorized users as needed.

5. How is Encryption different from Hashing?

Hashing and encryption are both cryptographic methods, however, they have different applications:

a) Encryption: Data is converted into a ciphertext using an encryption algorithm and a key in the reversible process of encryption. The same key can be used to decrypt the same data and restore it to its original state.

Data confidentiality is protected via encryption, which also makes sure that only people with permission can access the original data.

b) Hashing: Using a hash function, the one-way process of hashing reduces data to a fixed-length string of characters called a hash value. Since hashing is irreversible, it is impossible to recover the original data using the hash value.

Both password storage and data integrity verification use it. Hashes can be used to securely store and validate passwords without saving the actual passwords or to check if data has been altered (integrity).

6.  What is a Firewall and why is it used?

A firewall is a piece of hardware or software used in network security that creates a barrier between a trusted internal network and a network that is externally untrusted (such as the Internet).

Based on established security criteria, it is used to monitor and manage incoming and outgoing network traffic.

By blocking unwanted access, filtering malicious traffic, and guarding against cyberattacks, firewalls improve network security, ensuring the safety of

  1. Confidentiality,
  2. Integrity, and
  3. Availability of Data and Resources.

7. What is the difference between VA(Vulnerability Assessment) and PT(Penetration Testing)?

Both penetration testing and vulnerability assessment are security testing techniques, however, they have different goals:

a) Vulnerability Assessment (VA): A system, network, or application is evaluated systematically to find and evaluate any potential weaknesses.

Finding known vulnerabilities, often entails the use of automated scanning technologies, however, manual verification may also be present.

The main objective is to compile a list of vulnerabilities that must be fixed.

b) Penetration Testing (PT): PT, also referred to as ethical hacking, simulates actual intrusions on a system or network in order to identify vulnerabilities and gauge their potential consequences.

In contrast to VA, PT takes things a step further by actively exploiting flaws to see if they may be utilized to compromise the security of the system.

The main objective is to give a thorough review of a company’s security posture and identify any vulnerabilities that could be used by bad actors to their advantage.

8. What is a three-way handshake?

A connection between a client and a server is established via the TCP (Transmission Control Protocol) three-way handshake process. There are three steps to it:

a) SYN (Synchronize): To start the connection request, the client sends a SYN packet to the server.

b) SYN-ACK (Synchronize-Acknowledge): The server replies with a SYN-ACK packet to acknowledge the request and indicate that it is prepared to establish the connection after receiving the SYN packet.

c) ACK (Acknowledge): In order to acknowledge the server’s response, the client then sends an ACK packet. The client and server can now exchange data because the connection is deemed to be established.

9. What are the response codes that can be received from a Web Application?

Different HTTP response status codes can be returned by web applications to show how a client’s request was handled. Here are a few typical HTTP response status codes:

a) 200 OK: The server has provided the requested content as a result of the request’s success.

b) 201 Created: A new server resource, such as a new webpage or record, has been created as a result of the request.

c) 204 No Content: Although the request was successful, the body of the response contained no data.

d) 400 Bad Request: Due to a syntax error or other client-side problems, the server was unable to comprehend or process the client’s request.

e) 401 Unauthorized: To access the specified resource, the client must supply legitimate authentication information.

f) 403 Forbidden: The request has been understood by the server, but it cannot be fulfilled for a variety of reasons, including insufficient permissions.

g) 404 Not Found: The server did not have the requested resource.

h) 500 Internal Server Error: An all-purpose error message stating that something went wrong on the server while handling the request.

i) 502 Bad Gateway: The upstream server the server accessed to fulfill the request provided an incorrect response while serving as a gateway or proxy.

j) 503 Service Unavailable: Due to maintenance or overload, the server is momentarily unable to process the request.

10. What is traceroute? Why is it used?

A network diagnostic tool called a traceroute is used to track the path that data packets follow as they go from a source device to a server or destination device. It estimates the round-trip time (latency) to each node and assists in identifying the intermediary network nodes (routers) via which the packets pass.

In order to improve network performance and address connectivity difficulties, Traceroute is used to identify

a) Network Bottlenecks,

b) Pinpoint Bottlenecks, and

c) Fix Routing Issues.
