• Network Security

Pentesting methodology is a systematic approach used to identify and exploit vulnerabilities in a system to improve security.

• 1. Reconnaissance: Gather information about the target system.

• 2. Scanning: Identify open ports and services on the target system.

• 3. Gaining access: Exploit vulnerabilities to gain access to the system.

• 4. Maintaining access: Maintain access to the system for further testing.

• 5. Covering tracks: Rem...read more

OWASP is a standard used for security testing of APIs and Web Applications

• OWASP Top 10 is a widely recognized standard for web application security

• OWASP API Security Top 10 provides guidelines for securing APIs

• OWASP ZAP (Zed Attack Proxy) is a popular tool for testing web application security

White hat hackers are ethical hackers who use their skills to improve security, while black hat hackers are malicious hackers who exploit vulnerabilities for personal gain.

• White hat hackers are ethical hackers who work to improve security by finding and fixing vulnerabilities in systems.

• Black hat hackers are malicious hackers who exploit vulnerabilities for personal gain or to cause harm.

• White hat hackers may be hired ...read more

Blue team focuses on defense and prevention, while red team simulates attacks to test defenses.

• Blue team is responsible for defending against cyber threats and implementing security measures.

• Red team simulates real-world attacks to test the effectiveness of the blue team's defenses.

• Blue team works proactively to prevent security breaches, while red team works reactively to identify vulnerabilities.

• Blue team focuses on ...read more

Authentication verifies a user's identity, while authorization determines what actions a user is allowed to perform.

• Authentication confirms the user's identity through credentials like passwords or biometrics.

• Authorization controls access to resources based on the authenticated user's permissions.

• Example: Logging into a system with a username and password is authentication, while being able to view or edit specific fil

Secure authentication methods are crucial for protecting sensitive information.

• Use multi-factor authentication (MFA) to add an extra layer of security

• Implement strong password policies, including regular password changes

• Utilize biometric authentication such as fingerprint or facial recognition

• Employ single sign-on (SSO) for centralized authentication management

• Monitor and analyze authentication logs for suspicious acti

Hashing is one-way function for data integrity while encryption is two-way function for data confidentiality.

• Hashing is irreversible and used for data integrity verification.

• Encryption is reversible and used for data confidentiality protection.

• Hashing produces a fixed-length output (hash value) while encryption output length can vary.

• Example: Hashing - MD5, SHA-256; Encryption - AES, RSA

LFI allows an attacker to include files on a server through the web browser, while RFI allows an attacker to execute arbitrary code on a server.

• LFI stands for Local File Inclusion, where an attacker can include files on a server using a vulnerable script.

• RFI stands for Remote File Inclusion, where an attacker can execute arbitrary code on a server by including a remote file.

• LFI is limited to files that are already pres...read more

Mitigations for SQL injection include input validation, parameterized queries, stored procedures, and least privilege access.

• Implement input validation to ensure only expected data is accepted

• Use parameterized queries to separate SQL code from user input

• Utilize stored procedures to encapsulate SQL logic and prevent direct user input execution

• Follow the principle of least privilege to restrict database access rights

Blind based SQL injection is a type of SQL injection attack where the attacker sends SQL queries to the database and observes the result without actually seeing the output.

• Attacker sends SQL queries to the database and observes the behavior of the application to determine if the query was successful or not.

• No error messages are displayed to the attacker, making it harder to detect.

• Time-based blind SQL injection involve...read more

Password spraying is a type of cyber attack where attackers try a few common passwords against many usernames.

• Attackers use common passwords to try and gain access to multiple accounts.

• Unlike brute force attacks, password spraying involves trying a few passwords against many accounts.

• Attackers aim to avoid detection by not triggering account lockouts.

• Organizations can defend against password spraying by enforcing stron...read more

Implement account lockout, use strong passwords, and implement CAPTCHA

• Implement account lockout after a certain number of failed login attempts

• Encourage users to use strong passwords with a combination of letters, numbers, and special characters

• Implement CAPTCHA to prevent automated brute force attacks

• Consider implementing rate limiting to restrict the number of login attempts within a certain time frame

End goal is more important as it drives the overall direction and success of a project.

• End goal provides a clear vision and purpose for the project

• Procedures are important for achieving the end goal efficiently

• Flexibility in procedures may be necessary to adapt to changing circumstances

• Examples: In cybersecurity, the end goal of protecting sensitive data may require constantly evolving procedures to combat new threats
