Domain Name System (DNS) Security Threats

DNS Security Threats The Domain Name System (DNS) is a service used on both the Internet and private networks to translate Internet Protocol (IP) addresses to Fully Qualified Domain Names. Example, this service allows someone to type a FQDN like www.zymitry.com to reach the Zymitry web site instead of having to type in the domains IP address. Regarding… Read More »

Basics of Security Awareness: Users are the Weakest Link

Basic Principles of Security Awareness. Security experts consider system users the weakest link in information security. User skill levels and experience can greatly vary, and unlike automated controls, human users can be subject to fatigue, or be distracted, which can lead to mistakes resulting in vulnerabilities. Security awareness training is often a user’s first experience with information security.… Read More »

Mitigating Insider Security Threats

Threats from within an organization. Insider security threats are the most significant threat to today’s information systems. Insiders often have elevated access within an organizations information systems which often gives them a level of authorized access that can cause a lot of damage if misused intentionally, or unintentionally. In the SANS Reading Room article; Insider Threat Mitigation Guidance,… Read More »

Computer Incident Response Teams & Incident Response Policy

Computer Incident Response Teams (CIRTs or IRTs) play a crucial role in information security incident response. An effective Incident Response Policy is essential for guiding the team in handling incidents and ensuring a coordinated and efficient response. This policy should outline the steps, tasks, and procedures that need to be followed during incident response. It covers various aspects, including communication, escalation, incident tracking, reporting and documentation, investigation checklists, remediation checklists, evidence collection, forensics investigation, data retention, and more. Additionally, the article emphasizes the importance of proper security architecture, baselines, and processes for incident identification. It also highlights the containment, eradication, and recovery phases of incident response, emphasizing the need for caution, evidence gathering, problem correction, and system restoration. By following a well-defined incident response policy and learning from each incident, organizations can improve their incident response capabilities and better protect their systems and data.

Roles in Database Security

Roles play a crucial role in enhancing database security by granting and denying permissions to groups of users based on their job responsibilities. By effectively managing user access and privileges, roles reduce the security workload for administrators. This article explores the concept of roles in database security, including their benefits, types, and assignment methods. Discover how roles can streamline user access management, improve data protection, and contribute to a more secure database environment.

Guidelines for Media and Data Sanitization: Protecting Confidentiality

Media sanitization is a critical process that organizations must undertake when retiring or repurposing information systems. The goal is to ensure that sensitive data stored on media remains protected throughout the retirement process. NIST Special Publication 800-88 provides valuable guidance on media sanitization, emphasizing the need to safeguard the confidentiality of recorded information. There are two primary types of media: hard copy and electronic. Each requires specific measures to render data inaccessible. The process of sanitizing media involves three categories: Clear, Purge, and Destroy. Clear employs logical techniques to protect against simple data recovery methods, while Purge utilizes physical or logical techniques to make data recovery infeasible. Destroy involves techniques that deform or destroy the media, preventing any future use for data storage. Cryptographic Erase (CE) is an effective method when encryption is involved, rendering the data unrecoverable without the encryption key. Physical destruction techniques such as bending, drilling, cutting, shredding, and thermal destruction provide a robust defense against data recovery. By following these guidelines, organizations can effectively protect the confidentiality of sensitive information throughout the retirement process, mitigating the risks associated with data exposure and unauthorized access.

Building an Effective Red Team for Penetration Testing

Developing an Effective Red Team is crucial for organizations to assess and improve the security of their systems. Penetration testing, or pen-testing, allows simulated attacks to identify vulnerabilities and exploits. However, it requires skilled individuals who can think like attackers and bypass controls effectively. A qualified Red Team must have technical expertise, a malicious mindset, and proficiency in penetration testing tools. The Red Team leader should possess both technical knowledge and business acumen to identify opportunities and quantify threats. With an effective Red Team in place, organizations can uncover vulnerabilities and enhance their system’s security against real-world attacks
