Separation of duties (SoD) – also referred to as “Segregation of duties” – is a critical, yet often overlooked area of IT security. Essentially, the purpose of SoD is to help organisations protect themselves from fraudulent behaviour by ensuring that no single individual can act alone to subvert a critical process for their own personal gain. SoD is an area that comes under close scrutiny during compliance reviews, and will … Read more

Auditing file and folder accesses on Windows File Servers enables you to see whether any users are accessing or trying to access resources without authrization. A large proportion of organisations are not making the most of file server auditing, choosing to stick to native auditing processes which can be both time-consuming and complex. At Lepide, we recommend deploying a third-party solution (obviously…), such as LepideAuditor. With an increasingly mobile workforce … Read more

People generally think that auditing and monitoring are the same thing and, in some ways, they are. The differences between them are subtle, but important none-the-less. In short, auditing is done by auditors, and it is the auditors responsibility to make use of the available technology to aggregate and present the log data in a way that that can be understood and “monitored” by administrators and managers. While most modern … Read more

In every organization, Active Directory administrators need to be able to produce detailed reports on user access, object modification, privileged user activities and more. The reason for this may be down to external compliance requirements, IT security, litigation purposes or a combination of all three. Depending on the requirement, the urgency of such reports may vary. For example, if you are tracking Active Directory activities in order to maintain network … Read more

Many IT Administrators find it difficult to implement an in-depth and pro-active File Server Audit strategy. If an important event happens and you want to investigate, you may have to wade through gigabytes of event logs on the Windows devices; which can often be like finding a needle in a haystack. Event logs stored on Windows File Systems are so verbose that deriving meaningful information from them can be very … Read more

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

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

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
