MITRE ATT&CK Framework: A Deep Dive into Adversary Tactics The MITRE ATT&CK Framework is a globally recognized knowledge base that systematically documents the behavior, tactics, and techniques of cyber adversaries. It’s not just a reference guide, but a tool that empowers security professionals to build and enhance their detection, response, and mitigation strategies by understanding how attackers operate. This framework is indispensable for organizations aiming to defend their networks against sophisticated and evolving threats. What is the MITRE ATT&CK Framework? The MITRE ATT&CK Framework catalogs every phase of an adversary's lifecycle, helping cybersecurity teams understand how real-world attacks unfold. By breaking down the complex behavior of cybercriminals, MITRE ATT&CK gives defenders an edge in anticipating and preventing attacks. The name ATT&CK stands for Adversarial Tactics, Techniques, and Common Knowledge , representing the key compo...

CEH Hacking Methodology (CHM) The Certified Ethical Hacker (CEH) Hacking Methodology provides a structured approach for ethical hackers to identify and exploit vulnerabilities in systems and networks. This methodology not only helps in executing successful penetration tests but also ensures that ethical hackers can provide valuable insights into security improvements. The methodology is composed of several critical phases, each playing a vital role in the overall hacking process. 1. Reconnaissance Reconnaissance is the first step in the hacking process and serves as the foundation for the rest of the methodology. It involves gathering as much information as possible about the target before any direct interaction. This phase is further divided into two types: passive and active reconnaissance. Passive Reconnaissance Passive reconnaissance involves collecting information without directly engaging with the target. This method reduces the risk of detection and can often yield signi...

Information Security Overview 1. Elements of Information Security Information Security encompasses various elements that collectively protect sensitive data and maintain the functionality of systems. The main elements include: Confidentiality Ensures that sensitive information is accessible only to those authorized to have access. Mechanisms to ensure confidentiality include: Data Encryption: Transforming data into a coded format that can only be decoded by those who possess the key. Access Control: Implementing policies that restrict access to data based on user roles. Authentication: Verifying the identity of users attempting to access sensitive information. Integrity Integrity guarantees that information is accurate and unaltered during its lifecycle. Key methods to maintain integrity include: Hashing: Generating a fixed-size string representation of data that changes if the data is modi...
