Do not allow COM port redirection in RDP is the name of a security setting stated in Windows servers CIS benchmarks/STIGs. A COM port is an I/O interface that enables the connection of a serial device to a computer. In some cases COM ports are called “serial ports”. Most computers are not equipped with COM ports anymore but there are many serial port devices still used in computer networks.

In 2014 and with extensive community involvement NIST Cybersecurity Framework was created for private sector organizations in the United States. It is also aligned with other NIST standards and guidelines, such as NIST 800-53 and FedRAMP. NIST Cybersecurity Framework (CSF or Framework) is intended to be a living document that is refined and improved over time and was updated in 2018 and called CSF 1.1. We will be discussing NIST CSF 2.0.

The cybersecurity landscape is witnessing a phenomenon that has come to be known as the “Great Resignation” among Chief Information Security Officers (CISOs). The challenges faced by CISOs in coping with ever-increasing regulations, compliance mandates, and the need for skilled resources have reached a tipping point. Coupled with a lack of cooperation from the C-suite, these factors have led to a surge in burnout among CISOs.

The Center for Internet Security (CIS) team continuously release updates about cybersecurity best practices for new technologies. As of March 2023 all CIS Windows Server and Windows Workstation Benchmarks will be updated once a year to align with Microsoft’s update schedule. Major version updates that CIS will release (i.e., updating from v1.12.0 to v2.0.0) will account for significant changes in the operating system.

CIS Critical Security Control, known now as CIS Controls have recently been updated and revised in the CIS Controls v8 released by the Center for Internet Security (CIS). The CIS Controls are a collection of industry-recognized best practices for businesses dealing with data security risks. Such measures were created to make things easier and keep the IT operations and security teams attention on crucial tasks. In v8, CIS changes a little the perspective around baseline security and system hardening.

In the ever-evolving landscape of cybersecurity, organizations strive to safeguard their systems and data against emerging threats. Amidst this pursuit, CIS Benchmarks emerge as an indispensable resource, offering a wealth of knowledge and practical recommendations. But what exactly are CIS Benchmarks, and why are they highly regarded across industries?

South Korean cyber security organisation AhnLab has identified a breach in Microsoft SQL servers allowing deployment of Trigona ransomware. The attacks were threat actors using brute-force or dictionary attacks with obtained or guessed credentials to infiltrate externally accessible MS-SQL servers.

We recently engaged in a conversation with our team of experts regarding their ongoing server hardening project. We inquired about the obstacles encountered during manual hardening procedures and asked if they’d be willing to explain the underlying reasons for issues that arise when automation is not employed. Their latest encounter with a client provided a valuable opportunity to further expound on strategies to mitigate these challenges.

Sysctl is a command-line utility in Unix-like operating systems that allows users to view and modify kernel parameters at runtime. These parameters, also known as “tunable” or “kernel” parameters, control various aspects of the operating system’s behavior, such as network settings, memory management, file system behavior, and more. Each of these operating systems has their own implementation of sysctl, with slightly different options and syntax.

Digitally Encrypt Secure Channel Data is a security setting used for digitally securing the data that’s transmitted over the secure data channel network. The data transmitted between the domain member and the domain controller must be encrypted and secured with the latest technology to ensure that no unauthorized user gets access to the confidential data.
