A general-purpose hardware security module is a cryptographic device that complies with standards and employs strong encryption, physical security measures, and logical security controls to safeguard sensitive data. A hardware cryptographic module (HCM), secure application module (SAM), or personal computer security module (PCSM) are further names for an HSM.
User and entity behavior analytics (UEBA) is a cybersecurity system that uses algorithms and machine learning to detect anomalies in the behavior of corporate network routers, servers, and endpoints. UEBA aims to identify any unusual or suspicious behavior—instances where there are deviations from routine daily patterns of use. UEBA does more than just observe human behavior; it also observes machines. One day, a server in one branch office may receive thousands more requests than usual, indicating the beginning of a potential distributed denial-of-service (DDoS). It is possible that the IT administrator will not detect this sort of behavior, but UEBA will recognize it and take appropriate action.
Virtual machines (VMs) are displayed to the outside world in a manner similar to that of a physical machine. They typically run a full operating system and are connected to a network. It is not possible for the hypervisor to make several intercessions on behalf of the virtual machine because of the built-in separation between the guest and its host.
The most crucial element of your virtual environment is unquestionably the Hyper-V host. All of the systems under its purview are immediately at risk if it is compromised. But a computer system is what the Hyper-V host is first and foremost. It must be treated like any other computer system before being treated as a computer that is running a hypervisor. Of course, specific considerations are necessary because it will operate as a hypervisor.
As 2019 came to a close, organizations all around the world underwent a significant transformation in how they carried out their business. Nearly every corporation was impacted by the COVID-19 pandemic, and each one struggled to maintain operations while also introducing a new work culture known as remote work or work from home. Remote work became the new normal for many organizations with many analysts predicting that remote work is the future and it is here to stay.
The foundation of conventional networks is based on hardware devices that are used to route data between various nodes in a network. Malicious adversaries, on the other hand, take advantage of these network devices’ security misconfigurations to launch various network attacks, such as Distributed Denial of Service attacks. With the introduction of software-based networking, organizations have been able to lower the network attack surface through the use of automated security provisioning, improved network visibility, scalability of resources, and centralized control over the enterprise network. This article discusses the essential concepts of Software-Defined Networking, how it differs from the traditional networking approach, and how it can be leveraged to provide greater network security.
Cybersecurity breaches are prevalent, and numerous occur in corporations on a daily basis. While some incursions may be considered modest, many are severe with minimal monetary or data damage. Some are even disastrous. Network security monitoring is a technique that automatically analyses network devices and traffic for security flaws, threats, and suspicious activity. It can help organisations discover and respond to cybersecurity incidents fast.
Kerberos is a network authentication protocol based on client/server architecture. This protocol does not require users to provide their passwords; instead, it relies on tickets and keys for authentication. Kerberos is a commonly employed authentication protocol in Active Directory. Because of its popularity, it has drawn the attention of hackers worldwide attempting to exploit its security weaknesses and crack the protocol. This article goes over some of the most common Kerberos attacks, how to carry them out, and how to defend against them.
Servers need particular security implementations, because obtaining the information stored on the servers is the most profitable objective for an attacker. This blog post will help you secure your servers with simple and clear guidelines.
A web shell is a script that can be uploaded to a web server to facilitate remote machine administration. Internal or Internet-facing web servers can be infected, and the web shell is used to pivot to internal hosts.
It is essential to understand what is normal in order to recognize what is not normal, such as a connection to port 443 with cleartext traffic. It is not possible to examine hundreds of thousands of packets per day at a workstation. Should malicious traffic traverse our hunting grounds, we should have access to a variety of enterprise products, including open-source software, that will assist us with this task and, ideally, capture a substantial amount of it. In this article, we will discuss how to identify normal network traffic when analyzing packets. The purpose of this article is to train your eye should you ever be required to inspect live or saved network traffic (PCAP).
The network operating system (NOS) is a software-based networked environment that allows many workstations and computing devices to share resources. In 1990, Microsoft released Windows NT 3.0 that featured a NOS environment. Many aspects of the LAN Manager protocols and the OS/2 operating system were merged in this product. Over the next few years, the Windows NT NOS slowly evolved into Active Directory that was first formally deployed in Windows Server 2000.
Web application firewalls are some of the most recent developments in the field of firewall technology (WAFs). In this blog post, we will define what a web application firewall is, how it functions. We will also cover some of the benefits of using a web application firewall.
In this blog post we are going to make an introduction to how to secure wireless intrusion detection and prevention systems. Let’s start with a quick definition of IDPS as a refresher.
SMTP stands for Simple Mail Transfer Protocol. This protocol allows email messages to be sent from one computer to another. The Internet was originally designed to allow computers to communicate directly with each other, without human intervention. In order to send emails, you need to know the address of the recipient (the person or company who receives the message).
Security Information and Event Management (SIEM) is a software system that combines Security Information Management (SIM); an automated process of collecting data of log files into a central archive, and Security Event Management; a type of computer security that monitors, correlates and notifies users of events as they occur in a system; to collect, analyze and report on all security-related events happening in an organization. The goal is to provide real-time monitoring of security devices such as firewalls, antivirus software, intrusion detection systems, and other network-based systems for potential threats. This post will explore the benefits of implementing a SIEM in your business by highlighting some of its most important features.
People frequently pause to consider how the internet works. Along with the benefits of using the internet, there are drawbacks and risks. But what happens when you browse the internet? You could be using a proxy server at work, on a Virtual Private Network (VPN), or you could be one of the more tech-savvy people who always uses some kind of proxy server.
Perimeter Security technologies offer a wide range of security services, from basic firewall protection to end-to-end network and business security. In essence, perimeter security is a defense system built around your network to prevent malicious attacks from entering.
A DMZ network connects a company’s secure perimeter to unsecured external networks like the internet. Web servers and other externally facing systems can be located in the DMZ without jeopardizing the security of internal resources. This blog post will explain what DMZs are and why they are important components of traditional network security architectures. Even if best practices are followed, DMZs are not perfect security solutions. We will demonstrate how modern security solutions based on Zero Trust are better suited to the way businesses operate today.
Peer-to-peer networks are vulnerable. There are several ways that malicious code can spread from user to user. For example, some P2P networks rely on file-sharing programs called BitTorrent. These programs automatically download new files from other users. If a virus infects the program, it can spread rapidly. How can you defend against malicious content as a P2P user?
If you’ve ever used a Windows device, you’ve probably encountered updates frequently — just before shutting down your computer. Your device may occasionally prompt you to install critical updates. There are also six yearly feature updates that are required! What exactly are these Windows Updates? What is the distinction between various types of Windows Updates? Let us now examine them. Before we get there, let’s distinguish between Windows Updates and Microsoft Updates.
TCP/IP has innate flaws. It was meant to run on a government network with a small number of hosts that trusted each other. Security was not a priority for the creators. However, now the network has been expanded worldwide, our most critical concern is security. Therefore, some extra measures were required to protect conversations via the Internet. In this blog, we will explain what Internet Protocol Security is and how it can offer protection over networks.
Several approaches for creating a safe and authenticated channel between hosts have been presented. Finally, a better replacement to the SSL protocol was created which is TLS. In this blog we will make an introduction to Transport Layer Protection (TLS) protocol.
In this blog post, we are going to explain what Secure Sockets Layer (SSL), and Secure-HTTP (HTTP-S) protocols are and how they differ from each other.
