Cyber Security interview questions with detailed answers

Confidentiality, integrity, and availability (CIA) are three fundamental principles of cyber security. Confidentiality refers to keeping information private and limiting access to authorized individuals. Integrity involves ensuring that data remains accurate and uncorrupted. Availability refers to making sure that authorized users have access to data when they need it.

There are several steps you can take to protect your computer from malware and viruses:

• Install a reputable antivirus program and keep it up to date.
• Be cautious when downloading files or clicking links from unknown sources.
• Keep your operating system and applications up to date with the latest security patches.
• Use strong and unique passwords, and enable two-factor authentication where possible.
• Avoid using public Wi-Fi networks for sensitive transactions.

A firewall is a network security system that monitors and controls incoming and outgoing network traffic. It acts as a barrier between a trusted internal network and an untrusted external network (such as the Internet), and can prevent unauthorized access and protect against malicious traffic.

Here's an example of how to set up a basic firewall using iptables in Linux:

iptables -P INPUT DROP
iptables -P FORWARD DROP
iptables -P OUTPUT ACCEPT
iptables -A INPUT -i lo -j ACCEPT
iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
iptables -A INPUT -p tcp --dport 22 -j ACCEPT

The above commands set the default policy to drop incoming and forwarded traffic, allow all outgoing traffic, allow loopback traffic, and allow SSH traffic on port 22.

Encryption is the process of converting plaintext data into a coded form, known as ciphertext, to protect it from unauthorized access. The purpose of encryption is to ensure confidentiality, by making it difficult or impossible for unauthorized individuals to read the encrypted data.

Encryption works by using a mathematical algorithm to transform the original data into ciphertext, using a secret key. The key is needed to decrypt the ciphertext back into the original plaintext. Here's an example of how to encrypt a file using the OpenSSL command-line tool:

openssl enc -aes-256-cbc -in plaintext.txt -out ciphertext.txt

The above command uses the AES-256-CBC encryption algorithm to encrypt the contents of plaintext.txt and save the resulting ciphertext to ciphertext.txt. To decrypt the ciphertext, you would use a similar command with the -d option to indicate decryption mode, and the same key that was used to encrypt the data.

• Use a combination of upper and lower case letters, numbers, and special characters.

Here's an example of a strong password: H#42jLx8@nFg

2. Use machine learning algorithms to identify patterns and anomalies in the files that may indicate potential variants or risks to the organization.
3. Use machine learning algorithms to develop models that can identify known patterns of malware and use them to detect those patterns in the files.
4. Use the insights gained from the analysis to determine the level of risk posed by the malware samples and to take steps to mitigate the risk, such as blocking or quarantining the source of the threat or implementing other security measures, such as firewalls or intrusion detection systems.

To use a UEBA tool to identify potential insider threats and compromised accounts based on system logs and network flows, you can take the following steps:

1. Collect and consolidate system logs and network flows from different sources, such as firewalls, intrusion detection systems, and user activity monitoring tools.
2. Import the logs and flows into the UEBA tool, such as Splunk or IBM QRadar, to analyze the data.
3. Define behavioral patterns and baselines for each user and entity, including user activity, device usage, and network behavior.
4. Use machine learning algorithms to develop models that can detect deviations from normal behavior patterns and identify potential threats.
5. Use visualization tools, such as dashboards and alerts, to provide insights into the data and to make it easier for analysts to identify potential threats.
6. Use the insights gained from the analysis to take steps to mitigate the risk posed by insider threats and compromised accounts, such as revoking user access or implementing additional security controls.

To ensure that the settings in a configuration file for a SIEM system are secure and effective in detecting and responding to cyber threats, you can take the following steps:

1. Conduct a thorough security review of the configuration file to identify potential security vulnerabilities and areas of weakness.
2. Implement security best practices and standards, such as those outlined in the CIS Controls or NIST Cybersecurity Framework, to ensure that the settings in the configuration file are effective in detecting and responding to cyber threats.
3. Use a configuration management tool, such as Ansible or Puppet, to automate the process of implementing and maintaining secure settings in the configuration file.
4. Monitor the SIEM system for security events and incidents, and use the insights gained from the monitoring to continuously improve the security posture of the system.

To use a digital forensic investigation platform to identify the root cause of a security incident and provide evidence for legal proceedings, you can take the following steps:

1. Collect and preserve forensic images and log files from the affected systems and devices, using tools such as FTK Imager or EnCase.
2. Import the forensic images and log files into a digital forensic investigation platform, such as X-Ways or AccessData Forensic Toolkit, to analyze the data.
3. Use forensic analysis techniques, such as file carving, keyword searching, and timeline analysis, to identify potential evidence and clues related to the incident.
4. Use data analytics tools, such as machine learning algorithms or link analysis, to identify potential correlations and patterns in the data.
5. Use visualization tools, such as timelines, graphs, and charts, to provide insights into the data and to make it easier for analysts to identify potential evidence.
6. Document the investigation process and findings, and provide evidence that can be used in legal proceedings, if necessary.
