Data Hardening Quiz

What is data hardening?

• The process of backing up data to prevent loss

• The process of compressing data to save storage space

• The process of encrypting data to make it unreadable

• The process of securing data by implementing various measures to protect it from unauthorized access, modification, or destruction.

What are some common encryption techniques used in data hardening?

• MD5, DES, SSL

• RC4, Diffie-Hellman, ECC

• AES, RSA, SHA

• SHA-256, HMAC, Blowfish

What is an Intrusion Detection System (IDS) and how does it contribute to data hardening?

• An Intrusion Detection System (IDS) is a network device that helps optimize data transfer speeds. It contributes to data hardening by improving network performance and reducing latency.

• An Intrusion Detection System (IDS) is a software that helps protect against physical attacks on data centers. It contributes to data hardening by providing physical security measures such as biometric access control.

• An Intrusion Detection System (IDS) is a security tool that monitors network traffic and system activities to identify and respond to potential security threats or attacks. It contributes to data hardening by providing real-time monitoring and alerting capabilities, helping organizations quickly detect and respond to security incidents.

• An Intrusion Detection System (IDS) is a tool used to encrypt sensitive data and prevent unauthorized access. It contributes to data hardening by ensuring data confidentiality and integrity.

What are some secure coding practices that can enhance data hardening?

• Using weak passwords, not encrypting sensitive data, not implementing access controls, not updating software regularly

• Ignoring input validation, not using secure coding libraries and frameworks, not encrypting sensitive data, not updating software regularly

• Implementing weak access controls, not using secure coding libraries and frameworks, not encrypting sensitive data, not updating software regularly

• Input validation, using secure coding libraries and frameworks, implementing proper access controls, encrypting sensitive data, and regularly updating and patching software.

Why is backup and recovery strategy important in data hardening?

• Backup and recovery strategy is not important in data hardening.

• Backup and recovery strategy only adds unnecessary complexity to data hardening.

• Backup and recovery strategy is important in data hardening to ensure data integrity and minimize the impact of data loss or corruption.

• Data hardening can be achieved without backup and recovery strategy.

What is symmetric encryption and how is it used in data hardening?

• Symmetric encryption is a type of encryption where the encryption and decryption keys are randomly generated. It is used in data hardening by encrypting sensitive data to protect it from unauthorized access or tampering.

• Symmetric encryption is a type of encryption where the encryption key is different from the decryption key. It is used in data hardening by encrypting sensitive data to protect it from unauthorized access or tampering.

• Symmetric encryption is a type of encryption where different keys are used for encryption and decryption. It is used in data hardening by encrypting sensitive data to protect it from unauthorized access or tampering.

• Symmetric encryption is a type of encryption where the same key is used for both the encryption and decryption of data. It is used in data hardening by encrypting sensitive data to protect it from unauthorized access or tampering.

What is the difference between a host-based IDS and a network-based IDS?

• A host-based IDS is installed on network infrastructure and monitors the network traffic flowing through it, while a network-based IDS is deployed on individual hosts and monitors the activities and events occurring on that specific host.

• A host-based IDS and a network-based IDS are the same thing and can be used interchangeably.

• A host-based IDS only monitors network traffic, while a network-based IDS only monitors activities and events on individual hosts.

• A host-based IDS is installed on individual hosts and monitors the activities and events occurring on that specific host, while a network-based IDS is deployed on the network infrastructure and monitors the network traffic flowing through it.

What are some common vulnerabilities in software that can be mitigated through secure coding practices?

• Cross-site scripting (XSS), Cross-Site Request Forgery (CSRF), Denial of Service (DoS), Encryption, Firewall, Input Validation, Secure Socket Layer (SSL)

• buffer overflows, SQL injection, XSS, CSRF, insecure direct object references, security misconfigurations, unvalidated input

What are the key components of a backup and recovery strategy for data hardening?

• regular backups, offsite storage, encryption, testing and validation, and documentation

• regular backups, offsite storage, no encryption, no testing or validation, and no documentation

• regular backups, onsite storage, no encryption, no testing or validation, and no documentation

• infrequent backups, onsite storage, no encryption, no testing or validation, and no documentation

What is asymmetric encryption and how is it used in data hardening?

• Asymmetric encryption is a cryptographic method that uses two different keys, a public key and a private key, to encrypt and decrypt data. It is used in data hardening to protect sensitive information by encrypting it with the recipient's public key.

• Asymmetric encryption is a method that uses a public key and a private key to encrypt and decrypt data, but the keys are interchangeable.

• Asymmetric encryption is a method that uses the same key to encrypt and decrypt data.

• Asymmetric encryption is a method that uses a single key to encrypt and decrypt data.
