Penetration Testing, or "pen testing," is an offensive security practice where a simulated cyberattack is conducted against a system, network, or application to identify vulnerabilities that could be exploited by malicious attackers. It involves identifying potential weaknesses, misconfigurations, and other security flaws that could lead to a security breach. Pen testing can be manual or automated, and it often employs various tools and techniques used by real-world attackers.
2. Application Security AssessmentApplication Security Assessment (ASA) is a detailed evaluation of the security controls within an application to ensure it is protected against known and emerging threats. ASA includes reviewing the application's source code, architecture, design, and its implementation to identify and rectify vulnerabilities. Some areas that are assessed include:
A Red Team consists of security professionals who simulate real-world attacks on an organization’s infrastructure, often without prior knowledge of the system's defenses. Their goal is to test how well the organization can defend against a sophisticated, determined adversary.
Red Team exercises involve a comprehensive, multi-vector approach, mimicking actual attack patterns to test not only technical defenses but also incident response, security monitoring, and threat detection.
In a Purple Team setting, the two teams work together to refine defensive measures and learn from offensive strategies, aiming to improve detection, response times, and mitigation strategies.
Offensive security refers to the proactive and aggressive approach to protecting systems and networks by simulating real-world attacks to identify and fix weaknesses. It encompasses practices like penetration testing, Red Team operations, and exploit development. Offensive security professionals think and act like attackers, understanding the tools, techniques, and methodologies that adversaries use.
Mobile Application Security involves protecting mobile apps from threats and vulnerabilities that could compromise user data or system integrity. With the rise of mobile usage, ensuring security in both iOS and Android applications is critical. Mobile applications often face unique challenges due to platform-specific vulnerabilities, insecure communication methods, and improper data storage.
Network Security focuses on protecting the integrity, confidentiality, and availability of data as it moves across or is stored on networks. It includes a wide range of practices, tools, and technologies to prevent unauthorized access, misuse, or theft of data within a network.
Core elements of network security include:
Web Application Security focuses on securing web applications by finding, mitigating, and preventing vulnerabilities that could lead to unauthorized access or data breaches. Since web applications are accessible over the internet, they are often a prime target for attackers.
Common web application vulnerabilities include:
Web application security assessments involve testing the application for such vulnerabilities, ensuring proper input validation, secure session management, and the use of encryption for sensitive data.
10. Information SecurityInformation Security, or InfoSec, is the broad practice of securing all forms of sensitive information, whether it's in physical or digital form. The primary goal is to maintain the confidentiality, integrity, and availability (CIA) of data. InfoSec encompasses all the sub-disciplines mentioned above, with a focus on protecting data from unauthorized access, theft, or destruction.
