The dark web is a part of the internet consisting of hidden sites not indexed by conventional search engines. When you envision the dark web, it may conjure up images of hackers trading stolen  Social Security numbers or drug dealers advertising their products online—and that’s not completely wrong. While the dark web can be a helpful tool for sourcing legitimate products or ensuring private communication, it’s also a hotspot for illegal internet activity. The term “dark web" sounds ominous, and there's a reason for that.  The dark web is a part of the internet that's made up of hidden sites you can't find through conventional web browsers.  Instead, you must rely on the  Tor browser—a web browser that anonymizes your web traffic within its internal network—and search engines designed specifically to unearth these hidden sites. Dark websites use  encryption software so their visitors and owners can remain anonymous—it’s why the dark web is home to ...

Data center tiers are a classification system, ascending 1, 2, 3, and 4 – with some operators even pushing for 5  – that are used to evaluate data center facilities, consistently, regarding their potential site infrastructure  availability , also known as  uptime . Specifically, the tier ratings stipulate what a data center can offer in terms of  redundancy  and  resiliency , as well as how much potential  downtime  a customer could experience for a year. As a general rule, the difference between data center tiers is that tier 1 offers no redundancy of any critical system, tier 2 has partial redundancy in their electrical & HVAC systems, tier 3 contains dual redundancy for power & cooling equipment, and tier 4 possesses fully redundant infrastructure. Data centers are commonly rated by the  Uptime Institute , an independent organization, which has issued over 2,500 certifications to data centers in more than 110 countries. The Upt...

The chakra system refers to the energy centers we have in our bodies. There are seven major chakras in a specific location along your spine. Root Chakra The root chakra, or Muladhara, is located at the base of your spine. It provides you with a base or foundation for life, and it helps you feel grounded and able to withstand challenges. Your root chakra is responsible for your sense of security and stability. Sacral Chakra The sacral chakra, or Svadhisthana, is located just below your belly button. This chakra is responsible for your sexual and creative energy. It’s also linked to how you relate to your emotions as well as the emotions of others. Solar plexus Chakra The solar plexus chakra, or Manipura, is located in your stomach area. It’s responsible for confidence and self-esteem, as well as helping you feel in control of your life.  Heart Chakra The heart chakra, or Anahata, is located near your heart, in the center of your chest. It comes as no surprise that th...

  SIEM (Security Information and Event Management) is an important tool for financial institutions because it helps them detect, identify, prevent, and respond to threats quickly. SIEM provides a comprehensive overview of the security environment within a financial institution's network by using real-time analytics to monitor and alert on suspicious activity. It also assists with compliance activities by allowing organizations to meet regulatory requirements through detailed audit trails and reporting capabilities. Additionally, SIEM solutions enable businesses to reduce response time in the event of an attack by streamlining data collection, log management, and incident investigation processes. All of these benefits help ensure the security and stability of a financial institution's networks and systems, thus protecting sensitive customer data and funds. Since SIEM has the capability to detect, identify, prevent, and respond to threats rapidly it is obvious can save a lot of...

  Cyber security is a wide field covering several disciplines. It can be divided into seven main pillars:    1. Network Security Most attacks occur over the network, and network security solutions are designed to identify and block these attacks. These solutions include data and access controls such as Data Loss Prevention (DLP), IAM (Identity Access Management), NAC (Network Access Control), and NGFW (Next-Generation Firewall) application controls to enforce safe web use policies. Advanced and multi-layered network threat prevention technologies include IPS (Intrusion Prevention System), NGAV (Next-Gen Antivirus), Sandboxing, and CDR (Content Disarm and Reconstruction). Also important are network analytics, threat hunting, and automated SOAR (Security Orchestration and Response) technologies.       2. Cloud Security As organizations increasingly adopt cloud computing, securing the cloud becomes a major priority. A cloud security strateg...

  The PCI Digital Security Standard (PCI DSS) is a set of internationally-recognized security standards that exist to protect the sensitive data associated with payment accounts. These standards apply to any organization or other entity that manages cardholder data. As of March 2022, PCI DSS v4.0 is the most current version of these standards, though v3.2.1 will remain valid until the end of March 2024. PCI DSS defines 12 requirements, testing procedures for each requirement and guidance on best practices for implementation.  To be PCI compliant, an organization must implement and maintain security practices that meet or exceed these standards.  Why is PCI Compliance Important? Whether you're a large or small business, if you are a merchant who accepts credit card payments, or are a service provider to merchants, your organization is responsible and must protect payment cardholder data through PCI security standards and PCI services. With security breaches and cyber...
