Organizations are increasing their use of various solutions to address communication needs across their infrastructure. As file systems are an integral part of collaboration, this article will dive into one of the most widely used protocols necessary for many systems. We will learn more about the SMB protocol, Port 139, Port 445, how it works, the risks associated with it, and remediation steps to provide a more secure communication channel.

The Get-Mailbox cmdlet is a key command in the Exchange Management Shell (for Exchange Server) and in the Exchange Online PowerShell module (for Office 365). It is used to retrieve information about mailboxes in an Exchange environment.

You’re working late Thursday evening as a contractor for a powerful government agency. You stumble across classified documents uncovering a surveillance program that invades the privacy of millions of citizens. Your heart races as you decide to expose this to the masses and enlist the help of a few journalists. But you also know the organization you work for monitors emails (and other forms of communication). If your emails hit the wrong eyes, you could face severe penalties.

Windows Task Scheduler enables users to schedule tasks to run at a specific date and time, on a defined schedule, or when triggered by certain events. This built-in tool of Windows operating systems helps improve efficiency and ensure reliable execution of repetitive tasks. In this blog, we will show you how to run a PowerShell script from Task Scheduler and how to create scheduled tasks using PowerShell.

Let’s face it. Managing and securing IT networks is far more complex today. Beyond securing endpoints, sensitive data, and the network perimeter, security teams must also focus on identity security, access management, and regulatory compliance. They not only have to create password policies but protect those passwords and access privileges. Twenty years ago, no one had to worry about things such as cloud identity. Today, a different world demands a different set of tools.

PowerShell is one of the most popular platforms for malicious actors. To protect your critical data and systems, it’s vital to implement strategies for blocking and detecting attacks that exploit PowerShell. However, you should not assume those security measures are airtight — adversaries are constantly looking for ways to bypass your defenses. Let’s explore three of those techniques, so you can build an even more robust strategy for defending your data and your business.

Administrators can perform all typical Windows registry operations using either the old-good regedit user interface or the reg.exe utility. But there is another option — PowerShell. PowerShell can dramatically streamline the work of managing the registry, either on the local machine or remotely.

If your organization runs on Microsoft Active Directory, you rely on one or more domain controllers to keep AD operations going. On the surface, Active Directory seems to run on a peer-to-peer models in which every domain controller (DC) has the authority to create, modify, and delete AD objects. That is because every domain controller holds a writable copy of its domain’s partition, the only exception being read-only DCs.

Effective user management allows people to access resources while protecting the security and integrity of data and IT infrastructure. With the rise of remote work and cloud-based applications and infrastructure, user management is a foundational security measure. User management also streamlines the process of creating, controlling, and deleting user accounts, lightening the administrative burden on your IT team.

When intruders want to break into an establishment, they look for an opening. An open port is one of the openings that a hacker or threat actor looks for to access a digital network. That open port may be on a firewall, a server, or any network-connected computing device. Just as a single unlocked door can jeopardize your privacy and grant access to a physical building, a single open port can provide a point for hackers to breach your systems, exposing you to their malicious intents.
