OWASP & Cybersecurity Essentials: Threats, Tools, and Defenses

The Open Web Application Security Project (OWASP)

The Open Web Application Security Project (OWASP) is a non-profit foundation providing guidance on developing, purchasing, and maintaining trustworthy and secure software applications. It's an online community that produces free articles, methodologies, documentation, tools, and technologies in IoT, system software, and web application security.

Key Aspects of OWASP

• Origin: Started by Mark Curphey on September 9, 2001.
• Leadership: Jeff Williams was the volunteer Chair from late 2003 to September 2011. As of 2015, Matt Konda chaired the Board. Bill Corry was an OWASP Foundation Global Board of Directors officer in February 2023.
• Goal: To provide tools, resources, and guidelines to developers, businesses, and security professionals.
• Features: OWASP is open source, community-driven (combining work from experts and volunteers), and offers educational resources.

OWASP Top 10: Critical Web Application Risks

The OWASP Top 10 is a list of the 10 most critical security risks affecting web applications, based on consensus among the developer community. Its purpose is to educate developers, designers, architects, and business owners about common web application security vulnerabilities. The list is revised every few years to reflect industry and risk changes. The first version was published in 2003, with updates in 2004, 2007, 2010, 2013, 2017, and the most recent in 2021.

OWASP Top 10 (2021) List

• Broken Access Control: Does not restrict user access to certain areas.
• Cryptographic Failures: Flaw in encryption or decryption mechanisms.
• Injection: Invalid data sent into an application by a hacker.
• Insecure Design: Flaw in the design of the application.
• Security Misconfiguration: Wrong configuration of software or hardware.
• Vulnerable and Outdated Components: Software not patched with the latest updates.
• Identification and Authentication Failures: Identification or authentication not done properly.
• Software and Data Integrity Failures: Integrity of data compromised.
• Security Logging and Monitoring Failures: Failure to log or monitor events like login attempts.
• Server-Side Request Forgery: Attacker manipulates an application to send unauthorized requests to other systems.

Common Attack Vectors & Cyber Threats

Common attack vectors include phishing, insider threats, brute force attacks, and misconfiguration.

Types of Cyber Attacks

• Phishing: Uses email or SMS to trick insiders into clicking malicious links, leading to network access.
• Insider Threats: Employees, contractors, or other insiders leaking or destroying data, selling company secrets, or breaking IT resources.
• Brute Force Attacks: An attacker attempts to guess login credentials.
• Misconfiguration: Incorrectly configured software (e.g., firewalls) leading to data breaches.
• Viruses: Designed for easy transmission, corrupting data, interfering with security, generating spam, or deleting content.
• Computer Worms: Spread by sending themselves to user contacts and their contacts.
• Trojans: Malicious software inserted into legitimate programs, often voluntarily allowed by users through trusted emails or advertisers.
• Bogus Security Software: Tricks users into believing their system is infected, then provides fake fixes that cause the problem.
• Adware: Tracks browsing habits and causes advertisements to pop up, sometimes without consent.
• Spyware: Intrusion that steals sensitive data like passwords and credit card numbers.
• Denial-of-Service (DoS) Attack: Hackers overload a website with traffic, making it inaccessible.
• Distributed Denial-of-Service (DDoS) Attack: A more aggressive DoS initiated from multiple servers simultaneously, harder to defend against.
• SQL Injection Attacks: Infiltrate cyber vulnerabilities in data systems using malicious code, leading to data theft, alteration, or destruction.
• Man-in-the-Middle Attacks: A third party intercepts and manipulates communication between two private entities, potentially altering information or creating false data.
• Rootkits: Tools allowing remote and illegitimate access to computer systems, abusing resources, introducing malicious software, and compromising data.
• Cross-Site Scripting (XSS) Attacks: Malicious scripts injected into trusted websites, leading to sensitive data theft.
• Supply Chain Attacks: Attackers target trusted vendors to compromise their products or services, introducing malware, backdoors, or vulnerabilities.
• Session Hijacking: An attacker steals or predicts session tokens to gain unauthorized network access.
• Other Attack Vectors: Compromised credentials, weak credentials, missing or poor encryption, ransomware, and domain hijacking.
• Eavesdropping Attacks (Sniffing or Snooping): Theft of information transmitted over a network.
• MAC Spoofing Attacks: Changing a network device's MAC address to redirect data and gain access.
• Sybil Attacks: A malicious user creates multiple fake identities to gain influence and perform unauthorized actions in a network.
• Desynchronization Attacks: Disrupts the normal sequence of messages between endpoints, causing repeated message transmission and wasted energy.
• FTP Bounce Attacks: Exploits the FTP protocol's PORT command to request indirect access to ports through a victim machine.
• SMTP Smuggling Attacks: Attackers exploit inconsistencies in how email servers interpret end-of-message code to inject malicious emails with forged sender addresses.
• HTTP Flood Attacks: Overwhelming a server with HTTP GET or POST requests to exhaust its resources.
• Jamming Attacks: Attackers disrupt network connections by jamming signals.
• Bluejacking Attacks: Hackers send unsolicited messages to Bluetooth-enabled devices.
• Piggybacking Attacks: Unauthorized users access a network without permission.
• Rogue Access Point (AP) Attacks: Hackers connect an unauthorized access point to a network.
• Evil Twin Attacks: Hackers mimic an authorized access point to trick devices into connecting.
• Insecure Direct Object Reference (IDOR): Occurs when developers fail to implement authorization requirements, allowing attackers to access resources by simply changing an identifier.

Passive Attack Vector Exploits

• Attempts to gain access or use information without affecting system resources (e.g., typosquatting, phishing, social engineering).

Active Attack Vector Exploits

• Attempts to alter a system or affect its operation (e.g., malware, exploiting unpatched vulnerabilities, email spoofing, man-in-the-middle attacks, ransomware).
