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...

Introduction to RAM Forensics RAM forensics, or memory forensics, focuses on analyzing a computer's volatile memory (RAM) to extract information about what happened on the system during its operation. RAM can provide key insights that aren't available through disk forensics, such as running processes, network activity, malicious code injection, and more. Volatility: is one of the most popular open-source tools used to perform RAM forensics. It is platform-agnostic, supporting Windows, Linux, and macOS memory analysis. Prerequisites Before starting with Volatility, make sure you have the following: Memory Dump (Memory Image): You need a memory dump from the system you want to investigate. There are various tools you can use to capture a RAM image, such as: FTK Imager (Windows) DumpIt (Windows) WinPMem (Windows) LiME (Linux) Volatility Installed: Volatility can be installed using: Python Package: Install via pip i...

Ethics In Cybersecurity A - Security Ethics Guidelines for making appropriate decisions as a security professional. B - Ethical Principles in Security 1. Confidentiality 2. Privacy Protections  3. Laws 1. Confidentiality As a security professional, you'll encounter proprietary or private information, such as PII. It's your ethical duty to keep that information confidential and safe. For example, you may want to help out a coworker by providing computer system access outside of properly documented channels. However, this ethical violation can result in serious consequences, including reprimands, the loss of your professional reputation, and legal repercussions for both you and your friend. 2. Privacy Protections For example, imagine you receive a personal email after hours from your manager requesting a colleague's home phone number. Your manager explains that they can't access the employee database at the moment, but they need to discuss an urgent matter with that...

Frameworks, Controls And Ethics. Security Frameworks: Guidelines used for building plans to help mitigate risk and threats to data and privacy  Purpose of security frameworks: Protecting PII  Security financial information  Identifying security weaknesses  Managing organizational risks  Aligning security with business goals Four core components of frameworks: 1. Identifying and documenting security goals (e.g. EU general data protection regulation GDPR: A data protection law established to grant European citizens more control over their personal data.) 2. Setting guidelines to achieve security goals, e.g. when implementing guidelines to achieve GDPR compliance, your organization may need to develop new policies for how to handle data requests from individual users. 3. Implementing strong security processes. In the case of GDPR, a security analyst working for a social media company may help design procedures to ensure the organization complies with verified ...

The Eight CISSP Security Domains. 1. Security and Risk Management  => Defines security goals and objectives, risk mitigation, compliance, business continuity, and the law 2. Asset Security => Secures digital and physical assets.  It's also related to the storage, maintenance, retention and destruction of data  3. Security Architecture and Engineering  => Optimizes data security by ensuring effective tools, systems, and processes are in place.  4. Communication and Network security => Manage and secure physical networks and wireless communications.  5. Identity and access management  => keeps data secure, by ensuring users follow established policies to control and manage physical assets, like office spaces, and logical assets, such as networks and applications. 6. Security assessment and testing  => Conducting security control testimng, collecting and analyzing data, and conducting security audits to monitor for r...

The history of cybersecurity. Past Malware Attack examples: Brain virus 1980 Morris worm 1988 Loveletter 2000  Equifax breach 2017 Common types of malware attacks: Viruses: Malicious code written to interfere with computer operations and cause damage to data and software. A virus needs to be initiated by a user (i.e., a threat actor), who transmits the virus via a malicious attachment or file download. When someone opens the malicious attachment or download, the virus hides itself in other files in the now infected system. When the infected files are opened, it allows the virus to insert its own code to damage and/or destroy data in the system. Worms: Malware that can duplicate and spread itself across systems on its own. In contrast to a virus, a worm does not need to be downloaded by a user. Instead, it self-replicates and spreads from an already infected computer to other devices on the same network. Ransomware: A malicious attack where threat actors encrypt an organization's...

The first module of foundation of cyber, You study the following:  1. Common cybersecurity terminology 2. General Glossary terms in IT security  3. Technical cybersecurity analyst skills 4. Transferable cybersecurity analyst skills Common cybersecurity terminology Compliance is the process of adhering to internal standards and external regulations and enables organizations to avoid fines and security breaches. Security frameworks are guidelines used for building plans to help mitigate risks and threats to data and privacy. Security controls are safeguards designed to reduce specific security risks. They are used with security frameworks to establish a strong security posture. Security posture is an organization’s ability to manage its defense of critical assets and data and react to change. A strong security posture leads to lower risk for the organization. A threat actor , or malicious attacker, is any person or group who presents a security risk. This risk can relate to c...
