Misconfigured Domain Controllers (DCs) present a major security risk for Active Directory. To ensure that your Domain Controllers are configured correctly, you will need to closely review the default Domain Controller Policies, create Domain Controller GPOs (Group Policy Objects) and configure Group Policy Settings. Your policy will need to include patching and protecting Domain Controllers, and include an effective DC auditing strategy for monitoring and reporting changes to event logs. … Read more

Unlike an Information Security Analyst, to be a professional IT auditor, you are not strictly required to have an in-depth understanding of your operating system, nor do you need to be a hacker to be able to audit the files, folders and permissions on your network. However, it is imperative that the auditor knows exactly what they are auditing, which does require a high level of technical knowledge. There are … Read more

Attackers are persistent in their pursuit to compromise Active Directory services due to their role in authorising access to critical and confidential data. As organisations expand, their infrastructure becomes increasingly more complex, which makes them a lot more vulnerable to attack as it is harder to keep track of important system changes, events and permissions. It’s also becomes a lot harder for organisations to determine where their sensitive data is … Read more

Configuration drift is a naturally occurring phenomenon whereby configuration items (CIs), such as computers or devices on an organisation’s network, drift towards an inconsistent state. This problem occurs on both private and cloud-based networks. While there are a number of causes of configuration drift, it’s essentially the result of conflicting changes made to device’s, software, services and configuration files, which are not systematically monitored by the IT department. It is … Read more

The overall cost to the UK economy from cyber-crime alone is well over £20 billion, and businesses are the ones that feel the effects the most. Every year we see stories of network attacks, yet it appears that many businesses are still not taking steps to mitigate the risks. Surveys suggest that most companies that face a significant security breach go out of business within a year. The average cost … Read more

In many organizations, servers are managed without any oversight, and this often leads to unwanted configuration changes. Here are three reasons why you should consider implementing change control in your business, no matter how large or small. Change control is a business process that aims to ensure a systematic approach is taken to making configuration changes to IT systems. But many organizations don’t have a process for managing IT change, … Read more

The Active Directory is one of the most important security mechanisms for any Windows network. The Active Directory contains everything from user accounts and password policies, to group policy settings. As such, most organizations put considerable effort into determining which Active Directory settings will best meet the organization’s security requirements. Even so, all of this careful planning can be undone by configuration drift. Configuration drift happens when changes gradually occur … Read more

For many organizations, IT operations are driven by regulatory compliance requirements. Systems containing sensitive data must be secured and maintained in a way that adheres to the regulatory requirements. Industry specific applications, such Electronic Health Records systems, are commonly designed with regulatory compliance in mind. After all, the application vendor knows which industry will use the application, and what the regulatory requirements are for that industry, and can therefore design … Read more

For organizations that use Windows Server, nearly all authentication and access control related tasks are tied to the Active Directory. Additionally, application configuration information is also sometimes stored in the Active Directory. Given everything that the Active Directory does, it would not be a stretch to think of the Active Directory as being the glue that ties all of an organization’s IT resources together. Because the Active Directory is such … Read more

In this post, I’ll explain how Privileged Access Management (PAM) in Windows Server 2016 can be used to protect privileged credentials, and provide an outline of the solution’s architecture. It’s common to find IT staff assigned permanent domain administrator privileges, or others that are local administrators on devices used for managing the domain and sensitive systems, making it easier for malicious users to hack line-of-business systems. Adding users to privileged … Read more
