All the options mentioned such as using digital signatures, configuring trusted repositories and a review process for configuration changes will prevent from software and data integrity failures

The best solution to address this vulnerability is “All of the above.” This includes using strong hashing algorithms like bcrypt, scrypt, or Argon2 to securely store passwords, which prevents rainbow table and brute-force attacks. Additionally, applying proper input validation and sanitation when handling file uploads helps prevent attackers from exploiting vulnerabilities to access sensitive files. Finally, adopting secure coding practices ensures the overall security of the application. All these measures combined provide a robust defense against such attacks.

Correct Answer: Conversational AI-powered attacks

Conversational AI-powered attacks leverage advancements in deep learning and natural language processing (NLP) to automate social engineering campaigns and create hyper-realistic, personalized phishing messages. These attacks use AI models to analyze a target’s communication style, preferences, and social context, crafting phishing messages that appear genuine and tailored to the recipient.

Explanation of other options:

1. Botnet hijacking: This involves taking control of a network of compromised computers (botnets) to launch various attacks, such as DDoS or spam campaigns. It does not specifically leverage deep learning or NLP for social engineering.
2. Cloud-based malware delivery: This refers to using cloud infrastructure to host or distribute malware but is not related to deep learning or NLP-based social engineering techniques.
3. Zero-knowledge proof encryption: This is a cryptographic technique that allows one party to prove they know certain information without revealing the information itself. It is unrelated to social engineering or phishing attacks.

The best solution is “All of the above.”

Here’s why each measure is important for preventing this type of broken authentication attack:

1. Enable MFA (Multi-Factor Authentication): Adding an additional layer of security, such as MFA, significantly reduces the risk of unauthorized access even if an attacker cracks a user’s password.
2. Account Lockout: Implementing an account lockout mechanism after a certain number of failed login attempts helps prevent brute-force attacks, as attackers can’t endlessly try different password combinations.
3. Monitoring and Anomaly Detection: Continuous monitoring of user behavior and detecting anomalies, such as unusual login patterns or large fund transfers, can help identify and stop suspicious activities before damage is done.

By combining all these measures, the application can effectively prevent brute-force attacks and protect user accounts from unauthorized access.

Even with constant monitoring and installation in a high-security environment, software may still be vulnerable to zero-day attacks. Zero-day attacks exploit vulnerabilities in software that are unknown to the vendor and, therefore, have no available patches or fixes. Attackers discover and exploit these vulnerabilities before developers are aware of them, making it challenging for organizations to defend against such attacks until a security update is released. To mitigate the risk of zero-day attacks, organizations should focus on proactive security measures, including robust intrusion detection systems, threat intelligence, and rapid response capabilities. Regularly updating and patching software also remain crucial to address known vulnerabilities and reduce the attack surface.

The security concept that involves designing web applications with security in mind from the outset, considering potential vulnerabilities and threats throughout the development process

Fuzzing with AI/ML can pose a threat by potentially enhancing the capabilities of attackers to discover and exploit software vulnerabilities more efficiently. Artificial Intelligence (AI) and Machine Learning (ML) techniques applied to fuzzing can enable automated and adaptive generation of malicious inputs, increasing the chances of discovering previously unknown vulnerabilities. Attackers leveraging AI-powered fuzzing tools may find it easier to identify and target weaknesses in software, leading to more sophisticated and effective cyber attacks. The use of AI/ML in fuzzing introduces a new dimension of automation and intelligence to the threat landscape, emphasizing the need for robust cybersecurity measures to counter evolving attack techniques.

The attack that targets outdated and unpatched web application components like plugins or frameworks, often exploiting known vulnerabilities, is Supply chain attack

Enforcing strong password policies and implementing Multi-Factor Authentication (MFA) is a security best practice that can help secure web application sessions and prevent unauthorized access even if attackers steal a user’s password. MFA adds an additional layer of authentication beyond just a password, making it more difficult for attackers to gain unauthorized access even if they obtain the user’s credentials.

Correct Answer: Web application firewalls (WAFs)

Web Application Firewalls (WAFs) are specifically designed to monitor, filter, and analyze HTTP/HTTPS traffic between web applications and the internet. They help identify and block suspicious activity and potential attacks on a web application, such as SQL injection, Cross-Site Scripting (XSS), and other web-based threats.

Explanation of other options:

1. Firewalls: Traditional firewalls control network traffic based on predetermined security rules but do not have the specific capability to inspect and identify threats targeting web applications at the application layer.
2. Penetration testing: Penetration testing is an assessment technique that simulates attacks to find vulnerabilities. While it identifies weaknesses, it is a point-in-time activity and does not provide continuous monitoring of suspicious activities.
3. Patch management: This involves keeping systems up to date with the latest security patches. While essential for security, it does not provide real-time monitoring or detection of attacks on web applications.

Quantum computers have the potential to solve certain mathematical problems, such as factoring large numbers, much more efficiently than classical computers. This capability could be used to break widely used encryption algorithms, like RSA, which rely on the difficulty of factoring large numbers for their security. The increased processing power of quantum computers in performing such tasks could undermine the security of current encryption methods.

The correct answer is “XSS (Cross-Site Scripting).”

XSS vulnerabilities occur when attackers inject malicious HTML or JavaScript into web applications, which can then be executed in a user’s browser. The development team’s decision to restrict HTML input suggests they are trying to mitigate the risk of XSS, where malicious scripts could be injected into web pages viewed by other users.

1. CSRF (Cross-Site Request Forgery) involves tricking a user into performing unintended actions on a web application.
2. SQL Injection targets the database by injecting malicious SQL queries.
3. Command Injection exploits vulnerabilities to run system commands on a server.

Since the focus is on preventing HTML input, XSS is the most likely issue.
